An offensive security firm,
with a platform of its own.
Section 31 Security is a team of practitioners with more than two decades of combined experience across offensive and defensive cybersecurity operations. We deliver penetration testing, red team, incident response, and related advisory services to organizations across the private sector. We also build the autonomous penetration testing platform our consultants use alongside their own tooling.
To make rigorous security testing a continuous practice, not an annual ceremony.
The delivery model didn’t fit how teams actually work.
Section 31 was founded by offensive and defensive security practitioners whose backgrounds span national security, financial services, healthcare incident response, and the consulting practices that serve them. The team has run, defended against, and rebuilt from adversary operations in environments where security failures have real consequences.
That experience produced a structural observation: the yearly cadence of penetration testing — months of lead time, weeks of engagement, a report read once and filed — opens a gap between what an organization can verify about its security posture and what an attacker can discover in any given week. The platform was built to close that gap on the engagement side; the consulting practice continues to handle the work that requires direct human judgment.
Where we have done the work.
