Job Description

At Praetorian, our mission is to prevent breaches before they occur. We envision a world where cybersecurity is proactive, not reactive--where organizations shift from an "assume breach" mindset to a prevention-first strategy that keeps them ahead of evolving threats.

Through red team engagements, sophisticated attack simulations, and Chariot--our fully managed continuous threat exposure management platform--we help organizations stay in control of their dynamic attack surfaces. Our human-led, tech-enabled approach allows clients to uncover and remediate exploitable vulnerabilities before they can be leveraged by real-world threat actors.
