Rethinking Security Culture & Risk - Podcast EP 75 - Valentina Flores, Red Sentry

Valentina Flores, Co-Founder and CEO of Red Sentry, joins hosts Harry Baldwin and Matt Rose for another fantastic edition of The Cyber Security Matters Podcast. Valentina shares her unconventional journey from cybercrime detective investigating human trafficking and child exploitation cases to building a penetration testing company focused on real-world attacker simulation and practical risk reduction.

The conversation dives into why cybersecurity is fundamentally about people and psychology rather than just tools, the critical importance of diversity of thought and background in building effective security teams, and how organisations can move beyond checkbox compliance to proactive, human-centred security practices. Valentina emphasises starting simple, prioritising real risks, and fostering a culture where security is everyone’s responsibility.

Key Topics Covered

• Valentina’s path from SVU detective to cybercrime investigations and the surprising normalcy of hacker motivations
• Why cybercrime is “just like every other crime” - victim psychology, criminal psychology, and real-world attacker behaviour
• Building Red Sentry: pivots, funding, and a non-sales-focused approach centred on teaching and simplification
• Diversity beyond gender/race: the value of neurodiversity, unique backgrounds (including carnival life and law enforcement), and curiosity-driven hiring
• Human-led penetration testing, tabletop exercises, and why third-party ethical hackers uncover what internal teams miss
• Security culture in practice: integrating security into every department, honest adoption of tools, and avoiding tool fatigue
• Advice for new cybersecurity professionals: avoid putting yourself in a box and learn every side of the business
