How they differ

CISO Tribune files Armadin under Breach simulation and automated pen-testing as its primary category. CISO Tribune files Reflex Security under the same primary category, and also under Incident response and forensics and Security awareness training. Armadin describes an agentic AI, continuous offensive security platform that identifies and proves exploitable risk across the entire attack surface. Its platform charts the attack surface, enumerates hosts, profiles people and analyzes defenses, and it combines red team expertise with autonomous AI-driven attacker swarms. Armadin's platform has guardrails for controlled execution and scoped impact, and each validated kill chain comes with prioritized guidance.

Reflex Security sells Reflex, a crisis simulation platform that builds a live crisis from a team's real environment and adapts to each decision the team makes. In a Reflex exercise, the team works a live breach while an adaptive adversary and pressured stakeholders push back in real time. Reflex tests breach coordination across technical, legal and executive teams, and it produces an after-action report the moment the team finishes. So both companies work with simulated attacks, but Armadin's attacker agents probe an attack surface, while Reflex Security's agents play every side of a breach for the responding team.

On funding, Armadin announced on March 10, 2026 that it raised $189.9 million in Seed and Series A funding. On October 1, 2026, Armadin raised an additional $255.5 million in Series B funding, bringing its total funding to $445 million. Jake Seid, co-founder of Ballistic Ventures, led Armadin's seed round and joined the Armadin Board in 2026. Armadin's data agreements include jurisdiction-specific terms for customers in regions such as the EEA, UK, Switzerland, Canada and Australia.
