Adversis is a cybersecurity consulting firm that helps growth-stage SaaS companies achieve enterprise readiness—navigating security reviews, completing compliance certifications, and building security programs designed to withstand buyer-side scrutiny. The firm serves companies typically between $10M–$100M ARR that are selling into enterprise accounts and encountering security requirements for the first time—or hitting friction points their current resources can't address. Founded by offensive security practitioners with backgrounds at Capital One, Okta, Bishop Fox, Symantec, and Rivian, Adversis operates as a retained security partner rather than a transactional vendor. The team works alongside clients' engineering and sales organizations to prepare for and respond to enterprise security evaluations, including questionnaire completion, live calls with buyers' security teams, and penetration testing timed to deal cycles. Adversis provides hands-on support across four service areas: - Security Advisory & Fractional CISO: Architecture review, security questionnaire support, policy and control development, and executive-level security leadership for companies that don't yet have a dedicated security hire—or whose existing team needs specialist reinforcement. - Penetration Testing: Web, API, cloud, and network assessments with findings prioritized by realistic exploitability and business impact rather than generic severity scores alone. Reports are formatted for both technical teams and enterprise buyers reviewing them as part of procurement. - Compliance Programs: SOC 2 Type I/II, HIPAA, CMMC, and GDPR readiness engagements that pair certification achievement with underlying security improvements. Adversis works alongside compliance automation platforms like Vanta, Drata, and Secureframe to fill the gaps those tools don't cover. - Product Security: Threat modeling, authentication and authorization review, and secure architecture guidance embedded within development workflows. What distinguishes Adversis is direct experience on both sides of the enterprise security evaluation. The team has led vendor security assessments as enterprise buyers and negotiated over $50M in enterprise contracts from the vendor side. This background informs how Adversis prepares clients: not just achieving technical compliance, but building a security narrative that addresses what enterprise buyers actually evaluate. The team created the Red Team Maturity Model used by Fortune 200 companies and holds advanced certifications including OSCP, OSCE, and GXPN. Adversis is typically engaged by CTOs, heads of security, or sales leaders at SaaS companies where a specific enterprise deal, compliance requirement, or market expansion is driving the need for security expertise on a timeline that doesn't allow for a full internal build-out.
