Deloitte-1 is a CubeSat developed by Deloitte (United Kingdom) in collaboration with Spire Global, based on the Lemur satellite platform. The mission demonstrates on-orbit cyber security technologies using the Silent Shield payload.

The mission serves as a testbed for cyber anomaly detection, mitigation, and simulation of attacks against satellite systems. It supports development of threat tactics and procedures, while also enabling signal collection for applications such as maritime domain awareness and Earth monitoring. An onboard imager provides monochrome Earth observation data.

Deloitte developed the satellite with Spire Global using the Lemur platform. The primary payload, Silent Shield, is a proprietary out-of-band Intrusion Detection System (IDS) that monitors spacecraft data flows across space, link, and ground segments. It operates on isolated hardware with a one-way diode, ensuring it can observe telemetry and communications but cannot inject commands, mitigating trust model vulnerabilities in satellite architectures. Onboard machine learning enables real-time anomaly detection and reduces downlink data requirements.

Deloitte-1 operates at ~500 km altitude. Its imager has a ground sampling distance of 76 m, a swath width of 110 km, and captures VNIR monochrome images at 1440 × 1080 pixels (1.6 MP) and video at 60 fps. The satellite also carries a multi-frequency radio payload for signal collection.

The satellite was launched on a rideshare mission as Deloitte’s first spacecraft.
