Network traffic doesn’t lie the way an endpoint agent can be blinded or a log source can be tampered with. That’s the pitch behind network detection and response, and in September 2026 three vendors are fighting over who does it best: Darktrace, Vectra AI, and ExtraHop. All three landed as Leaders in the 2026 Gartner Magic Quadrant for NDR, which almost never happens across an entire competitive set in the same cycle. But “all Leaders” doesn’t mean “interchangeable.” Contract data pulled from third-party buyer reports this year shows a median Darktrace deal running around $55,200 a year, while a median ExtraHop RevealX contract lands near $234,000, a gap of roughly $179,000 for organizations comparing the two head-to-head. Vectra AI, meanwhile, just picked up FedRAMP High authorization in August 2026, opening a federal buying lane neither competitor has matched. This comparison breaks down the specs, the pricing, the detection philosophy, and the actual buying decision behind Darktrace vs Vectra AI vs ExtraHop, using vendor disclosures, Gartner recognition data, and third-party contract benchmarks current as of September 18, 2026.

What Network Detection and Response Actually Does in 2026
Network detection and response platforms sit on the wire, or increasingly on a cloud VPC mirror, and watch every packet or flow record that moves across an environment. Unlike endpoint detection and response, NDR doesn’t need an agent installed on every device, which matters enormously for IoT sensors, OT equipment, unmanaged BYOD devices, and legacy servers that can’t run modern EDR software. The category exploded in relevance once attackers started living off the land inside networks rather than dropping obvious malware, because behavior-based detection catches lateral movement and command-and-control traffic that signature-based tools miss entirely.
The category grew out of an uncomfortable reality: most breach investigations find that attackers were inside a network for days or weeks before anyone noticed, moving between systems using legitimate credentials and administrative tools rather than obvious malware. A well-tuned NDR platform is often the first tool to flag that kind of quiet lateral movement, because it’s watching the traffic pattern itself rather than waiting for an endpoint agent to flag a file hash or a SIEM rule to trigger on a known indicator of compromise. That’s also why NDR keeps showing up as a mandatory line item in cyber insurance questionnaires and regulatory frameworks that require continuous network monitoring, not just perimeter firewalls.
Darktrace, Vectra AI, and ExtraHop approach this problem from three distinct technical angles. Darktrace built its reputation on unsupervised machine learning that forms a live model of “normal” for an organization and flags deviations without needing pre-labeled attack data. Vectra AI leans on what it calls Attack Signal Intelligence, a hybrid of supervised detection models trained on known attacker tradecraft plus behavioral analytics that prioritizes which alerts actually matter. ExtraHop takes a cloud-scale approach built around packet and flow-level visibility through its RevealX platform, emphasizing raw network telemetry depth over autonomous decision-making. Buyers researching an EDR vs XDR vs MDR comparison often land here next, because NDR fills the network-layer gap that endpoint-only tooling structurally cannot see.
Darktrace ActiveAI Security Platform: Self-Learning AI Explained
Darktrace markets its current offering as the ActiveAI Security Platform, built around the DETECT and RESPOND modules that made the company’s name in the network security space. The self-learning premise is straightforward in concept: instead of matching traffic against known attack signatures, Darktrace’s AI builds a statistical baseline of how every device, user, and connection on a network normally behaves, then flags anything that deviates from that baseline regardless of whether the technique has ever been seen before. The vendor states its platform detects and contains novel threats an average of eight days before they become publicly disclosed vulnerabilities, a claim built on Darktrace’s own incident telemetry rather than an independent lab test.
In 2026, Darktrace pushed two notable updates into the platform: enhanced agentic AI paired with new endpoint visibility features, closing what the company describes as gaps between network-only and endpoint-only defenses, and separately, automated forensics capabilities that let analysts reconstruct an incident timeline without manually pulling raw packet captures. Darktrace has also branched into email security with Darktrace/EMAIL, which was named a Challenger (not a Leader) in Gartner’s first-ever Magic Quadrant for Email Security Platforms, a useful data point for buyers evaluating whether to consolidate email and network defense under one AI vendor versus keeping them separate.
On the recognition side, Darktrace says it was the only vendor named a Customers’ Choice in the 2025 Gartner Peer Insights Voice of the Customer report for NDR, and it reports 595 verified Gartner Peer Insights reviews as of October 2025 carrying a 4.8 out of 5 average rating, a figure the company says grew past 600 reviews by May 2026. That review volume alone makes Darktrace the most-reviewed NDR product tracked on the Gartner Peer Insights platform, according to the vendor’s own citation of Gartner data.
Vectra AI Platform: Attack Signal Intelligence and the Agentic SOC
Vectra AI positions its core differentiator as Attack Signal Intelligence, a detection layer designed specifically to cut through alert fatigue rather than simply generate more alerts. The company cites an independent IDC study showing customers achieved a 391% three-year return on investment and reduced alert noise by up to 80%, a number that matters more to SOC managers than raw detection counts because analyst burnout from false positives is one of the leading causes of missed real incidents.
The platform ships in two commercial packages: Vectra AI Platform Standard, which covers Network, Identity, and Cloud detection, and Vectra AI Platform Complete, which adds premium support and managed detection and response on top. In 2026 Vectra launched what it calls its next-generation platform alongside Vectra AI Pro, a product aimed at accelerating what the industry now calls the “agentic SOC,” meaning AI agents that triage and in some cases resolve lower-severity alerts without waiting for a human analyst. Vectra AI Pro was showcased at Black Hat USA in Las Vegas starting August 5, 2026.
The bigger 2026 headline for Vectra is federal market access. In August 2026, Vectra AI achieved FedRAMP High authorization through a partnership with Knox Systems, distributed via Carahsoft, which is the government reseller most federal agencies use to procure cleared software. Neither Darktrace nor ExtraHop has a comparable FedRAMP High authorization documented in current vendor materials, which makes Vectra the default answer for U.S. federal buyers who need NDR inside a high-impact environment. Corporately, Vectra AI remains privately held; its last publicly disclosed funding round closed in April 2021 at $130 million, valuing the company at $1.2 billion at the time, with no newer funding, acquisition, or IPO news surfacing in 2025 or 2026 reporting.
ExtraHop RevealX: Cloud-Scale Network Visibility
ExtraHop markets its platform under the RevealX name, split into two delivery models: RevealX 360, a SaaS deployment, and RevealX Enterprise, a self-managed deployment for organizations that need to keep data on-premises for compliance reasons. The company’s 2026 positioning leans hard on the phrase “network visibility for the agentic enterprise,” reflecting the same industry-wide pivot toward AI-agent-aware security that Vectra and Darktrace are also chasing, though ExtraHop’s technical emphasis stays closer to raw packet and flow analytics at scale rather than autonomous response.
ExtraHop was named a Leader in the Gartner Magic Quadrant for NDR for the second consecutive year in 2026, matching Darktrace’s two-year Leader streak. The company also published a 2026 Total Economic Impact report evaluating RevealX’s return on investment, a Forrester-style methodology commonly used by enterprise software vendors to quantify cost savings and risk reduction for prospective buyers. Where ExtraHop pulls ahead structurally is scale: RevealX 360 pricing is driven by discovered devices, daily record ingest capacity, and the record lookback period an organization selects (commonly 30, 90, or 180 days), while RevealX Enterprise is priced on discovered devices alone. That billing model rewards large, high-throughput networks that need deep historical lookback for forensics, but it can get expensive quickly for organizations with large device counts and long retention requirements.
Ownership-wise, ExtraHop has not shown any 2025-2026 signal of a change in its capital structure; it remains privately held under its existing investor group. Buyers evaluating cloud workload protection alongside network visibility frequently pair this research with a CNAPP platform comparison, since ExtraHop’s SaaS-first RevealX 360 model sits closer to how CNAPP vendors price than Darktrace’s module-based licensing does.

Pricing Breakdown: What Each NDR Platform Actually Costs
None of the three vendors publishes a list price, which is standard for enterprise security software sold through direct sales teams and channel partners. That said, third-party contract benchmarking firms have gathered enough anonymized transaction data in 2026 to sketch a real cost picture, and the spread between vendors is significant enough to matter for budget planning.
| Vendor | Entry-level deployment | Mid-market (500-2,000 devices) | Large enterprise / Fortune 500 | Notable cost detail |
|---|---|---|---|---|
| Darktrace | $85K-$180K/year (single-module, ~2,500 users, network DETECT only) | $150K-$500K annual contract value | $1.8M-$4.8M for full multi-module platform deals | Median deal $55,200/year; 75th percentile around $131,000 per Vendr transaction data |
| Vectra AI | $499/month for AI Platform Standard via AWS Marketplace | $150K-$400K annual contract | $1.5M-$3M+ for Fortune 500 platform deals | Per-IP enterprise NDR pricing benchmarked between $8 and $22 per protected IP per year |
| ExtraHop | 30-day RevealX 360 free trial, then quote-based | ~$234,000 median annual contract (3rd-party buyer reports) | Scales with monitored throughput; no published enterprise ceiling | Estimated hidden costs of roughly $5,880 initial setup plus $27,355/year ongoing management |
The practical takeaway: Darktrace’s entry point is the cheapest way into a Gartner Leader-rated NDR product for a small-to-mid enterprise, Vectra’s per-IP enterprise pricing tends to scale more predictably for larger flat networks, and ExtraHop’s device-and-ingest model rewards organizations that need deep retention windows but punishes those with sprawling device counts. Buyers should also budget for the add-on costs that vendor benchmarking firms flag separately from the base license, including sensor hardware or virtual appliance licensing, SPAN/TAP infrastructure, and SOC integration work to feed NDR alerts into a SIEM or XDR platform for correlation.
Gartner Magic Quadrant 2026: How the Three Leaders Stack Up
The fact that Darktrace, Vectra AI, and ExtraHop all landed in the Leaders quadrant of the 2026 Gartner Magic Quadrant for Network Detection and Response is itself the headline story of this comparison year. It’s rare for an entire shortlist of three vendors to cluster in the same quadrant, and it signals that the NDR category has matured past the point where “Leader” alone differentiates a purchase decision. Buyers now need to look past the quadrant placement and into the underlying Ability to Execute and Completeness of Vision axes, along with Gartner’s separate Critical Capabilities report, which scores vendors against specific use cases like hybrid cloud detection, OT/IoT visibility, and threat hunting depth.
Darktrace differentiates on customer satisfaction data specifically. Being named the sole 2025 Gartner Peer Insights Customers’ Choice for NDR is a distinct recognition from Magic Quadrant placement. It’s generated from verified end-user reviews rather than analyst evaluation, and Darktrace’s 595-plus reviews at a 4.8 average give it the largest review sample size of the three vendors by a wide margin. Vectra AI’s standout recognition sits in Gartner’s Critical Capabilities report specifically for signal intelligence, meaning independent analysts scored its noise-reduction and prioritization capability above peers on that particular axis. ExtraHop’s second consecutive year as a Leader shows platform stability rather than a single breakout year, which matters to risk-averse enterprise buyers who worry about vendors falling out of the Leaders quadrant after an acquisition or leadership change.
Detection Philosophy: Self-Learning AI vs Attack Signal Intelligence vs Cloud-Scale ML
The technical argument between these three platforms boils down to a tradeoff between autonomy, precision, and raw visibility depth.
Darktrace’s unsupervised approach
Darktrace’s unsupervised model doesn’t need labeled attack data to function, which theoretically makes it stronger against genuinely novel attack techniques that have never been catalogued anywhere. The tradeoff is a longer learning curve during initial deployment while the AI builds its baseline of “normal,” and a historical reputation (deserved or not, depending on the deployment) for generating more alerts during that ramp-up window before the model stabilizes.
Vectra’s signal-first approach
Vectra’s Attack Signal Intelligence leans toward known attacker tradecraft patterns layered with behavioral scoring, which trades a small amount of theoretical novel-threat coverage for a measurable, IDC-validated reduction in alert volume. For SOC teams already drowning in tickets from a dozen other tools, an 80% noise reduction claim is often worth more in practice than marginal gains in exotic threat coverage.
ExtraHop’s visibility-first approach
ExtraHop’s cloud-scale ML sits closer to a network performance monitoring heritage, which shows in RevealX’s strength at east-west traffic visibility, packet-level forensics, and long lookback retention. Teams that need to answer “show me exactly what this device did over the last 90 days” tend to favor ExtraHop’s approach, even if it means a more analyst-driven workflow than Vectra’s alert-prioritization model.
Encrypted Traffic Analysis and Deployment Architecture
More than 95% of enterprise network traffic now runs encrypted, so every serious NDR vendor has to detect threats without decrypting payloads in most deployments, relying instead on metadata: connection timing, packet size distributions, JA3/JA4 TLS fingerprints, DNS query patterns, and certificate anomalies. Here’s a simplified, illustrative example of the kind of metadata record an NDR sensor extracts from an encrypted session without ever touching the payload itself:
{
"flow_id": "f8c3-91ab",
"src_ip": "10.2.14.87",
"dst_ip": "198.51.100.23",
"dst_port": 443,
"tls_ja3_fingerprint": "e7d705a3286e19ea42f587b344ee6865",
"sni": "update.example-cdn.net",
"bytes_in": 148230,
"bytes_out": 2104,
"session_duration_ms": 3820,
"anomaly_score": 0.87,
"baseline_deviation": "new_destination_for_host"
}That kind of record, multiplied across every connection on a network, is what feeds the ML models behind all three platforms. Darktrace’s deployment spans network sensors plus cloud and OT connectors depending on which modules an organization licenses. Vectra’s packaging separates Network, Identity, and Cloud detection into distinct product lines that can be bought independently or as a bundle. ExtraHop draws the clearest architectural line of the three: RevealX 360 ingests via cloud-hosted sensors and record storage, while RevealX Enterprise keeps everything self-managed on customer infrastructure, a distinction that matters enormously for organizations under data residency or sovereign cloud requirements similar to those covered in comparisons of sovereign cloud providers.
Third-Party Benchmark Data: What Independent Sources Actually Say
Vendor marketing claims mean little without independent confirmation, so it’s worth separating what comes from Gartner, IDC, and third-party contract data trackers from what comes straight from a press release. Gartner’s 2026 Magic Quadrant for NDR is the single most consequential data point in this comparison because it independently placed all three vendors in the Leaders quadrant, a rare outcome that reflects Gartner’s own Ability to Execute and Completeness of Vision scoring rather than anything the vendors self-reported. Underneath that headline placement, Gartner’s separate Critical Capabilities for NDR report broke out signal intelligence and prioritization as a distinct scoring axis, and that’s where Vectra AI’s citation specifically comes from rather than from the broader Magic Quadrant.
IDC supplies the second major independent data point, having conducted the ROI study behind Vectra’s 391% three-year return and 80% alert-noise-reduction figures. IDC studies of this type are typically commissioned by the vendor but conducted with IDC’s own survey methodology across a sample of paying customers, which puts them a step above a vendor’s internal case studies but still short of a fully blind, vendor-agnostic benchmark. ExtraHop’s equivalent is its 2026 Total Economic Impact report, built on Forrester’s TEI methodology, which quantifies cost savings and risk reduction using discounted cash flow modeling rather than simple before-and-after alert counts.
The third major independent data source is contract-level pricing intelligence from firms like Vendr, Vendorbenchmark, and CostBench, which aggregate anonymized transaction data from real buyers rather than relying on vendor-published pricing (none of the three vendors publishes a list price, as established above). Vendr’s transaction data is what produces the $55,200 median Darktrace deal and the roughly $131,000 75th-percentile figure cited earlier, while CostBench’s buyer-report aggregation is the source for ExtraHop’s $234,000 median annual contract. None of the three benchmark firms currently publishes a directly comparable median figure for Vectra AI at the same granularity, which is why this comparison relies on Vectra’s per-IP and tiered contract-range data instead. No independent, vendor-neutral MITRE ATT&CK evaluation results or third-party phishing/BEC-style catch-rate testing for any of the three NDR platforms turned up in 2025-2026 research for this comparison, which is a gap buyers should ask vendors to address directly with a proof-of-concept rather than relying on marketing claims alone.
Real-World Use Cases: Which NDR Platform Fits Which Organization
Beyond the abstract buyer profiles, it helps to walk through how the decision actually plays out across common enterprise environments.
Federal and government agencies
Agencies operating under FedRAMP High requirements have effectively one option among these three today. Vectra AI’s August 2026 authorization through Carahsoft, achieved in partnership with Knox Systems, is the only FedRAMP High-level clearance documented among the three vendors, which makes it the default shortlist entry for any federal SOC or defense contractor bound by that requirement, regardless of how the other two platforms compare on raw detection quality.
Manufacturing and critical infrastructure
A manufacturing operator running programmable logic controllers, SCADA systems, and a mix of legacy Windows and modern IT infrastructure needs visibility across IT and OT without deploying agents on equipment that can’t run them. Darktrace’s module coverage across network, cloud, OT, and email under one self-learning AI baseline is built for exactly this kind of mixed environment, and it avoids the integration overhead of stitching together separate OT-specific and IT-specific tools from different vendors.
Mid-sized SOC teams fighting alert fatigue
A SOC running two to five analysts against a stack of EDR, SIEM, and cloud security tools is exactly the buyer profile IDC’s ROI study describes, where an 80% cut in alert noise translates directly into analyst hours reclaimed for proactive threat hunting instead of ticket triage. Vectra AI’s Attack Signal Intelligence is built specifically to compress a flood of raw detections into a short list of prioritized, high-confidence signals, which is the single biggest lever a resource-constrained SOC has for closing its detection-to-response time gap.
Financial services and healthcare with compliance retention needs
Regulated industries that need to reconstruct exactly what happened on a compromised device 60 or 90 days after the fact, for audit or breach-notification purposes, lean toward ExtraHop’s packet-level forensics and configurable lookback windows. The tradeoff is cost: RevealX’s device-and-ingest pricing model means a large hospital network or bank with tens of thousands of monitored devices should expect to land well above the $234,000 median contract figure once retention and throughput requirements scale up.
Cloud-first companies with minimal on-prem footprint
A company running almost entirely in AWS, Azure, or Google Cloud with a small physical office footprint doesn’t want to manage sensor hardware. ExtraHop’s RevealX 360 SaaS delivery model, plus its 30-day free trial (the only publicly documented trial among the three vendors), makes it the lowest-friction way to pilot NDR without a hardware procurement cycle or a multi-week sensor deployment project.
Organizations standardized on an existing SIEM or XDR ecosystem
Detection quality matters less than integration depth for a team that already has a mature SIEM or XDR deployment absorbing alerts from a dozen other sources. A mismatch here creates the same alert-correlation headaches documented in comparisons like CrowdStrike vs Sophos vs SonicWall for managed detection and response, where the wrong pairing turns a high-fidelity NDR signal into just one more noisy feed the SIEM has to normalize.
Migration Guide: Switching NDR Platforms Without Creating Blind Spots
Ripping out an incumbent NDR platform and standing up a new one is riskier than most software migrations because a gap in coverage during cutover is exactly the window attackers count on. Security teams planning a move between Darktrace, Vectra AI, and ExtraHop, or bringing NDR into an environment for the first time, should follow a staged approach rather than a hard cutover.
- Inventory every SPAN port, TAP, and cloud VPC mirror currently feeding the incumbent tool, and confirm the new vendor’s sensor requirements match your existing network topology before signing a contract.
- Run the new platform in parallel with the incumbent for a minimum of 30 days, since all three vendors’ AI models need a baseline-learning period before detection quality stabilizes.
- Export historical incident and alert data from the outgoing tool for at least 90 days of lookback, since forensic investigations often reference incidents discovered weeks after the fact.
- Map integration points into your SIEM, SOAR, and ticketing systems separately for each platform; Vectra, Darktrace, and ExtraHop use different alert schemas and API structures, so existing correlation rules will need rewriting, not just repointing.
- Re-tune alert thresholds and suppression rules from scratch rather than importing them from the old platform, since each vendor’s baseline scoring model works differently and imported thresholds routinely produce either alert floods or silent gaps.
- Train SOC analysts on the new console and alert taxonomy before cutover day, ideally through the vendor’s own certification path, since misreading a new platform’s severity scoring during a live incident is a common early-migration failure mode.
- Decommission the old sensors only after a full quarter of parallel operation confirms detection parity on at least one simulated or real incident, and keep exported historical data accessible for audit and compliance retention requirements.
- Document the new platform’s data residency and retention configuration immediately, particularly if switching to ExtraHop RevealX 360’s cloud-hosted model from a self-managed deployment, or vice versa.
Ownership and Corporate Stability: Thoma Bravo, Bain Capital, and Vectra’s Funding Story
Corporate ownership rarely makes it into a technical comparison, but for enterprise security software with multi-year contracts, it’s a legitimate risk factor. Darktrace was taken private by Thoma Bravo in 2024, and nothing in 2026 reporting indicates a change to that ownership structure, meaning the company continues operating under private equity ownership rather than as a publicly traded entity. Private equity ownership typically brings tighter cost discipline and product-line consolidation, which can show up as pricing pressure or feature bundling changes for existing customers over a multi-year contract term.
ExtraHop remains under its existing investor group, with no 2025-2026 reporting surfacing a new funding round, acquisition, or ownership change. Vectra AI’s most recent disclosed capital event dates back to April 2021, when it raised $130 million at a $1.2 billion valuation; the company has gone nearly five years without a newer disclosed funding round, acquisition offer, or IPO filing surfacing in current reporting, which for a company competing at this stage of the NDR market is worth noting even though it isn’t necessarily a red flag on its own. None of the three vendors is publicly traded, so buyers evaluating long-term vendor viability are relying on private-market signals like Gartner recognition and enterprise contract volume rather than public financial disclosures.
Pros and Cons of Each Platform
Darktrace ActiveAI Security Platform
Pros: broadest module coverage across network, cloud, OT, email, and endpoint under one AI baseline; largest Gartner Peer Insights review base with a 4.8/5 average; lowest entry-level pricing among the three for single-module deployments; strong fit for mixed IT/OT critical infrastructure environments.
Cons: no FedRAMP High authorization documented, ruling it out for many federal workloads; private equity ownership under Thoma Bravo introduces long-term pricing uncertainty; unsupervised learning model requires a baseline-building period that can generate noisy alerts early in deployment; largest gap between entry pricing ($85K-$180K) and full-platform enterprise pricing ($1.8M-$4.8M) among the three vendors.
Vectra AI Platform
Pros: only vendor of the three with FedRAMP High authorization as of August 2026; independently validated 391% three-year ROI and up to 80% alert noise reduction via IDC study; per-IP enterprise pricing ($8-$22/IP/year) scales predictably for large flat networks; Vectra AI Pro’s agentic SOC features target the exact alert-fatigue problem most SOC teams report as their top pain point.
Cons: no disclosed funding, acquisition, or IPO activity since April 2021, a longer capital-quiet period than either competitor; smaller publicly documented review volume on Gartner Peer Insights than Darktrace; module packaging (Network, Identity, Cloud) can require multiple line items to match Darktrace’s or ExtraHop’s broader single-platform coverage.
ExtraHop RevealX
Pros: only vendor offering a publicly documented free trial (30 days on RevealX 360); clearest architectural split between SaaS and self-managed deployment for data residency needs; deepest packet-level forensics and retention window flexibility (30/90/180-day lookback); second consecutive year as a Gartner Magic Quadrant Leader shows sustained execution.
Cons: highest median annual contract value among the three at roughly $234,000; billing tied to discovered devices and ingest capacity can scale unpredictably for organizations with sprawling device counts; no FedRAMP High authorization documented; estimated hidden costs (~$5,880 setup, ~$27,355/year ongoing management) add meaningfully to total cost of ownership beyond the base license.
The Verdict: Which NDR Platform Wins in 2026
There isn’t a single winner here, and the Gartner data backs that up directly: three Leaders in the same Magic Quadrant cycle means the analyst firm itself sees rough parity in execution and vision across these vendors. The decision comes down to which variable matters most to a given organization’s budget and risk profile.
If the deciding factor is total cost of entry and breadth of coverage across IT, OT, and email under one AI model, Darktrace’s $85K-$180K entry tier and multi-domain module lineup make it the most budget-flexible starting point, provided the organization can tolerate a private-equity-owned vendor and doesn’t need federal authorization. If the deciding factor is alert fatigue and measurable ROI, Vectra AI’s IDC-validated 80% noise reduction and its unique FedRAMP High status make it the strongest choice for SOC teams underwater in tickets or for any organization selling into or operating within federal infrastructure. If the deciding factor is raw network visibility depth, long retention, and deployment flexibility between SaaS and self-managed, ExtraHop’s RevealX platform justifies its higher $234,000 median contract with the only free trial and the deepest packet-level forensics of the three. For most mid-market buyers without a federal mandate, the combination of Darktrace’s entry pricing and its Customers’ Choice satisfaction data makes it the safer default; large enterprises with dedicated SOC teams chasing measurable alert-fatigue reduction should put Vectra AI’s Attack Signal Intelligence in the top slot for a proof-of-concept.
Frequently Asked Questions
What’s the difference between NDR and EDR?
Endpoint detection and response requires an agent installed on each device and watches process, file, and memory activity locally. Network detection and response watches traffic on the wire or in cloud VPC mirrors and doesn’t require an endpoint agent, which makes it the only visibility option for IoT, OT, and unmanaged devices that can’t run EDR software.
Is Darktrace still owned by Thoma Bravo in 2026?
Yes. Darktrace was taken private by Thoma Bravo in 2024, and current 2026 reporting shows no change to that ownership structure. The company continues operating as a privately held, private-equity-owned business rather than a publicly traded one.
How much does Vectra AI cost per year?
Vectra doesn’t publish list pricing. Third-party contract benchmarks put mid-market annual contracts between $150,000 and $400,000, large enterprise and Fortune 500 platform deals between $1.5 million and $3 million or more, and enterprise NDR pricing benchmarked at $8 to $22 per protected IP per year. A smaller AWS Marketplace listing shows Vectra AI Platform Standard starting at $499 per month for limited-scope deployments.
Does ExtraHop offer a free trial?
Yes, ExtraHop offers a 30-day free trial of RevealX 360, its SaaS-delivered NDR product. This is the only publicly documented free trial among Darktrace, Vectra AI, and ExtraHop as of September 2026.
Which NDR vendor has FedRAMP authorization?
Vectra AI achieved FedRAMP High authorization in August 2026 through a partnership with Knox Systems, distributed via the government reseller Carahsoft. Neither Darktrace nor ExtraHop has a comparable FedRAMP High authorization documented in current vendor materials.
Can NDR replace a SIEM?
No. NDR platforms detect and prioritize network-layer threats but don’t replace the centralized log aggregation, long-term correlation, and compliance reporting a SIEM provides. Most enterprise security stacks run NDR as a high-fidelity alert source feeding into a SIEM or XDR platform rather than as a standalone replacement for one.
What is Attack Signal Intelligence?
Attack Signal Intelligence is Vectra AI’s branded detection framework that combines behavioral analytics with models trained on known attacker tradecraft to prioritize which alerts represent genuine threats. Vectra cites an independent IDC study showing customers cut alert noise by up to 80% using this approach.
How is NDR pricing typically calculated?
Pricing models vary by vendor. Darktrace prices per user, mailbox, endpoint, identity, or OT asset depending on which modules are licensed. Vectra AI prices enterprise deployments per protected IP address. ExtraHop prices RevealX 360 based on discovered devices, daily record ingest capacity, and the retention lookback window selected, while RevealX Enterprise is priced on discovered devices alone. All three vendors keep final contract pricing quote-only rather than publishing a fixed list price.
