Security Chaos Engineering for CISOs - The Strategic Edge

Against Modern Threats

By Andres Andreu, CISO and COO, Constella Intelligence

In an age where cyber attackers have become more intelligent, agile, persistent, sophisticated, and
empowered by Artificial Intelligence (AI), defenders must go beyond traditional detection and prevention.
The traditional models of protective security are fast becoming diminished in their effectiveness and
power. In the face of pursuing a proactive model one approach has emerged, security chaos engineering.
It offers a proactive strategy that doesn't just lead to hardened systems but can also actively disrupt and
deceive attackers during their nefarious operations.

By intentionally injecting controlled failures or disinformation into production-like environments, defenders
can observe attacker behavior, test the resilience of security controls, and frustrate adversarial
campaigns in real time.

What is Security Chaos Engineering?

Security chaos engineering is the disciplined practice of simulating security failures and adversarial
conditions in running production environments to uncover vulnerabilities and test resilience before
