Adversis

Adversis is a cybersecurity consulting firm that helps growth-stage SaaS companies achieve enterprise readiness — not initial checkbox compliance, but the security maturity that holds up as buyer scrutiny gets more sophisticated. The firm serves companies between $10M–$100M ARR whose early security programs are no longer sufficient for the enterprise customers they're pursuing.

Founded by offensive security practitioners from Capital One, Okta, Bishop Fox, Symantec, and Rivian, Adversis operates as a retained security partner. The team has spent years inside enterprise environments mapping what actually leads to compromise, and brings that pattern recognition to client engagements — identifying where real exposure exists, what to prioritize, and what to skip.

Core services include:

• Security advisory and fractional CISO support for companies whose security team needs strategic direction, not just execution
• Penetration testing with findings prioritized by realistic exploitability and business impact
• Compliance programs including SOC 2, HIPAA, and CMMC readiness, delivered alongside platforms like Vanta, Drata, and Secureframe
• Product security including threat modeling and secure architecture guidance for platforms entering regulated verticals

The team has led vendor security evaluations as enterprise buyers and negotiated over $50M in enterprise contracts from the vendor side. This experience on both sides of the evaluation is what allows Adversis to speak from operational experience rather than frameworks. The team created the Red Team Maturity Model used by Fortune 200 companies and holds certifications including OSCP, OSCE, and GXPN.

Adversis is typically engaged by CTOs, heads of security, or sales leaders at SaaS companies where the security program that got them to $10M won't get them to $100M.
