The Red Sentry Story

Alex Thomas

CTO, Founder

Valentina Flores


With a background in hacking and detective work, our founders Alex and Valentina set out to bring a more offensive, modern approach to the outdated, tedious, and reactive process that’s surrounded pentesting for years.

Alex started his career as an ethical hacker, eventually working as a penetration tester, hacking into fortune 500 companies all day long. Valentina began her career as a police detective, assigned to a federal taskforce and eventually landing in cybercrimes.

Though different, these paths led Alex and Valentina towards a mutual frustration of the reactive nature of cyber-security and penetration testing, with so many companies spending millions of dollars just to play defense and respond to threats long after they surfaced.

This is why Alex invented the Red Sentry software platform, a tool that could help people take action before they were victim to a hack. Pairing this software with a team of seasoned pentesters, Red Sentry has created a hybrid approach that allows businesses to get a thorough manual pentest quickly, while also utilizing the Red Sentry software, to ensure year around security.

This new take on the pentesting process has allowed Red Sentry to establish itself as a new leader in the pentesting market, providing manual pentests at a speed and cost never before seen in this space.
