What Tetra Defense does
Tetra Defense, founded in 2016, was a cyber incident response (IR) firm specializing in first-responder services for major cyber incidents and breaches. The company established a preferred-partner relationship with cyber insurance carriers, providing IR services to policyholders experiencing breaches, and also engaged directly with large enterprise organizations needing specialized breach response expertise. Its service scope spanned threat containment through business restoration, delivered as professional services engagements. The firm operated with 51-100 employees and was headquartered in the United States.
Following its 2022 acquisition by Arctic Wolf Networks Inc., Tetra Defense was rebranded as Arctic Wolf Incident Response and integrated into Arctic Wolf's broader security operations portfolio. Within Arctic Wolf, the IR capability is anchored by the Aurora Superintelligence Platform, which layers AI-driven prevention, detection, and response across endpoint, cloud, and identity surfaces, including the Aurora Agentic SOC and Aurora AI. The combined platform-plus-modules architecture also encompasses Managed Detection and Response (MDR), Cloud Detection and Response (CDR), Exposure Management, Cloud Security Posture Management, Endpoint Security, Security Awareness & Training, Threat Intelligence Plus, the Incident360 Retainer, and risk-transfer products including a Security Operations Warranty of up to $3M, a Cyber Insurance program, and the Cyber JumpStart portal.
Commercially, Tetra operated on a professional services revenue model distributed through direct enterprise sales (a 'Request a Demo' channel) and channel partnerships with cyber insurance carriers who referred policyholders. Pricing was not publicly disclosed. Marketing was channeled through Arctic Wolf's content engine — security bulletins, threat reports, case studies, webinars, and virtual events — across a global, multi-language footprint.
