The adversary you hire before the one you fear shows up.
PRAETORIAN, N. - A cybersecurity firm whose logo is a letter "P" drawn as a maze, a quiet nod to a company of problem solvers. It prevents breaches by thinking like the attacker, then handing clients the map. Photographed here as the square company mark.
Most security vendors sell you a scanner and a dashboard. Praetorian sells you an adversary. The Austin-based firm builds its work around a single premise - that the best way to find out how you would be breached is to have skilled people try, then automate the parts a machine can do faster.
Founded in 2010 by Nathan Sportsman, a University of Texas at Austin electrical and computer engineering graduate who had done tours at Sun Microsystems, Symantec, and McAfee, Praetorian grew for roughly a decade without outside money. It took a single funding round - a $10 million Series A in February 2020 - from McKinsey & Company and Texas venture investor Bill Wood. In an industry that runs on venture capital, that restraint is itself a statement.
The company's mission is stated plainly: "Prevent breaches before they occur." Its people are described as security engineers rather than consultants, recruited from computer science, software engineering, and physics. That distinction shows up in the product. Instead of a report that lands in a drawer, Praetorian embeds with client teams, emulates live attacker techniques, and stays until the compromise path is closed.
Prevent breaches before they occur.
The portfolio splits into a platform and the human expertise that feeds it. The platform is Chariot; the expertise is a red team you can rent, plus open-source tooling anyone can use.
A Continuous Threat Exposure Management (CTEM) and attack surface management platform. It maps exposure from the outside-in like an adversary, cross-checks it inside-out with cloud data, and has red-team experts validate real compromise paths. Available as a managed service or self-managed software.
A machine-learning and regex secrets scanner that finds passwords, API keys, and credentials left in code and config. Benchmarked scanning the Linux kernel's source history on a laptop in about five minutes. Regex capabilities were open-sourced in December 2022.
Penetration testing, red and purple team engagements, assumed-breach exercises, and threat-actor emulation - delivered by engineers who integrate with a client's own security team.
Security testing across software, IoT, mobile, and automotive products - including FDA testing for medical devices - plus cloud penetration testing across AWS, Azure, and GCP.
The perennial problem in security is not too little data - it is too much. Scanners generate thousands of findings, most of which no attacker would ever bother with. Praetorian's pitch is prioritization: use an adversary's outside-in view plus a customer's inside-out cloud data to surface the exposures that actually lead somewhere, and let human red teamers eliminate false positives.
Praetorian works with large enterprises where a breach is an existential event - technology, finance, healthcare, and automotive. Publicly cited clients include Amazon, Google, Microsoft, Netflix, Salesforce, and Stripe. In market terms it sits alongside offensive-security and pentest-as-a-service firms like Bishop Fox, NetSPI, Synack, and Coalfire, and attack-surface-management players such as CyCognito and Randori - but its combination of a homegrown CTEM platform with embedded human red teams is what it uses to stand apart.
Praetorian is B2B. Revenue comes from three overlapping streams: recurring managed security services delivered on retainer, the Chariot platform sold both as a managed offering and as self-managed SaaS, and project-based engagements like penetration tests and red team exercises. The platform-plus-people design means automation scales the margin while human expertise keeps the differentiation.

Praetorian runs on eight stated principles - customer-first, transparency, "Yes, and" innovation, high impact ("Make craters"), humility, transformative over incremental, performance, and following individual passion. The recruiting bar reflects it: computer science, software engineering, and physics backgrounds, hired as engineers rather than consultants.
The logo is a letter "P" drawn as a maze - a deliberate nod to a team of problem solvers.
The name evokes the Praetorian Guard, the elite protectors of Roman emperors.
