What is Praetorian?

Founded in 2010 by Nathan Sportsman and headquartered in Austin, Texas, Praetorian positions itself around 'continuous offensive security.' It pairs traditional consulting with Chariot, a platform combining external attack-surface management, continuous testing, and AI-driven workflow automation to surface exploitable issues on an ongoing basis.

Best for: Tech and regulated enterprises wanting continuous offensive testing folded into a single subscription rather than annual one-offs

Pros

  • Chariot supports continuous, year-round testing rather than annual point-in-time pentests
  • Strong engineering culture with mature internal tooling and automation
  • Bootstrap-grown firm with stable leadership and long consultant tenure
  • Service model designed to satisfy annual testing requirements across multiple frameworks in one program

Things to check

  • Chariot subscription pricing is enterprise-tier with no public list
  • Primarily U.S.-based delivery with smaller international footprint
  • Continuous-testing model is a poor fit for buyers needing only a single compliance pentest
