Raised $16.4M (announced 2026-03-04) led by Seneca Partners, a modest round for a company with $189M in total funding raised since 1995.
Long-standing defense, intelligence, and enterprise customer base for its cyber-range and readiness platform, per the company.
New investment round closed 2026-03-04 alongside the launch of RangeGPT and Project Ares GEN3 platform updates.
Cyber-range/training-simulation is an established category for Circadence; the AI layer (RangeGPT) is an incremental rather than category-defining update.
Decades of defense and enterprise customer relationships suggest real operational value, though no independent third-party efficacy study was cited.
Cyber readiness training and threat simulation remain relevant, though this is a narrower training/simulation use case rather than a core detection or prevention control.
Why CISOs Should Care
Circadence provides AI-driven cyber readiness, threat modeling, and cyber-range training (Project Ares) so security teams and defense organizations can train for and rehearse response to modern cyberattacks before they happen.
What Makes It Different
A long-established (founded 1995) cyber-range and readiness vendor now layering generative AI into its platform via RangeGPT and Project Ares GEN3, combining decades of defense/enterprise training relationships with new AI-driven simulation capability.
