No Alerts, Still Breached: Understanding Cybersecurity Risks and Ethical Leadership in Healthcare AI'

Send a text

This episode explores ethical leadership and AI governance challenges in healthcare cybersecurity, emphasizing the risks of undetected breaches.'

In this episode of The Signal Room, Chris Hutchins speaks with Guman Chauhan, a cybersecurity and risk leader, about one of the most dangerous conditions in modern organizations: being breached and not knowing it. While dashboards stay green and alerts stay quiet, attackers increasingly operate using valid credentials, normal behavior patterns, and long dwell times—remaining invisible for weeks or months.

Guman explains why “no alerts” is often mistaken for “no breach,” and why silence is one of the most misleading signals in cybersecurity. The conversation unpacks how attackers deliberately avoid detection, why security tools alone do not equal security outcomes, and where organizations create blind spots through untested assumptions, alert fatigue, and fragmented processes.

They explore why undetected breaches are more damaging than known ones, how time compounds risk once attackers are inside, and what separates organizations that mature after incidents from those that repeat the same failures. Guman emphasizes that proven security is not built on policies, certifications, or dashboards—but on continuous testing, validated detection, and teams that know how to act under pressure.

This episode is a practical guide for executives, security leaders, healthcare organizations, and regulated enterprises that need to move from assumed security to proven breach readiness.

Topics Covered

• Why undetected breaches are more dangerous than known breaches
• How attackers use valid credentials to avoid detection
• Why “no alerts” does not mean “no breach”
• Alert fatigue and the signal-to-noise problem
• Security tools vs security outcomes
• Visibility gaps, unknown assets, and logging failures
• External penetration testing and real-world validation
• Cultural and leadership factors in breach response
• Assumed security vs proven security

Key Takeaways

• Silence is not security; it often means you are not seeing the right signals.
• Most breaches go undetected because attackers behave like legitimate users.
• Security tools do not fail—untested assumptions do.
• Alert fatigue hides real risk by normalizing noise.
• Proven security requires testing detection and response end to end.
• Mature organizations treat breaches as learning moments, not events to hide.
• Confidence without validation creates the most dangerous blind spots.
