Praetorian vs Bishop Fox
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.
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

Bishop Fox
Founded in 2005 (originally as Stach & Liu), Bishop Fox positions itself as 'the leading authority in offensive security' and is headquartered in Tempe, Arizona. Beyond traditional consulting it sells Cosmos, a continuous attack-surface management and offensive-testing platform that pairs automated discovery with human operator validation.
Pros
- Cosmos delivers continuous human-validated testing, not point-in-time engagements
- Strong consultant brand and notable open-source releases (Sliver C2 framework)
- Active Bishop Fox Labs research output and conference presence
- Highly tenured consultant base focused exclusively on offensive security
Things to check
- Premium pricing aimed at upper mid-market and enterprise, no public price list
- Cosmos requires meaningful integration and a minimum spend
- Largely U.S.-centric delivery footprint compared with global rivals
