Praetorian is an offensive security company headquartered in Austin, Texas, founded in 2010 by CEO Nathan Sportsman. It began as a penetration testing and security services firm and bootstrapped for roughly a decade, reporting profitability before taking outside capital.
Its platform, launched in 2022 as Chariot and now presented on its website as Praetorian Guard, combines automation and agentic AI with the company’s offensive security engineers. It covers attack surface management, vulnerability management, threat intelligence, attack path mapping, continuous penetration testing and breach and attack simulation, and is positioned as a continuous threat exposure management (CTEM) offering. The company continues to publish vulnerability research and an annual offensive security outlook report.
In February 2020 Praetorian closed a $10M Series A with McKinsey & Company and Bill Wood Ventures, alongside a strategic partnership with McKinsey. Crunchbase News reported revenue of $12.4M as of August 2019 and named clients including Zoom, Google, Microsoft and Samsung.
Innovation Matrix Assessment
Moved from services to a platform (Chariot, now Guard) and continues to add AI-driven and autonomous testing features, with frequent research output in 2026.
Pairing continuous discovery with human-validated exploitable findings cuts triage noise and maps directly to CTEM programs and pen-test requirements.
Long-standing enterprise client base and profitable growth, but modest outside funding ($10M in 2020) relative to venture-scale ASM competitors.
Human-plus-platform continuous offensive testing is a strong model but now shared by several ASM, CTEM and PTaaS vendors.
Well-known offensive research team and clients named in press coverage; performance metrics on its site are vendor-stated rather than independently tested.
Continuous exposure validation is becoming a standard program requirement, keeping this approach relevant over the next 3-5 years.
Why CISOs Should Care
Gives security leaders validated, exploitable findings across their external and internal attack surface instead of raw scanner output, and can replace point-in-time penetration tests with continuous testing.
What Makes It Different
Platform findings are backed by an in-house offensive engineering team, combining automated discovery with human-verified exploitation in one managed CTEM offering.
The Matrix Verdict
63/100 — INCREMENTAL INNOVATOR
Praetorian scores 38/60 (63.3), placing it in the Incremental Innovator tier. It is a credible, research-driven offensive security firm whose platform model is solid but increasingly common in the CTEM market.
Editorial Note: Claims vs. Verified Findings
Independently verifiable: 2010 founding, the $10M Series A with McKinsey, 2019 revenue and named clients reported by Crunchbase News and others. Vendor claims: 25-50% spend reduction, 70% faster remediation and reduced low-impact remediation work, stated on its own site without independent testing. Headcount comes from third-party aggregators.
