Key Takeaways:

- AI changes the economics of attacks, not the fundamentals of defense. Attackers now find vulnerabilities, chain them, and tailor malware faster and cheaper than ever, but the defenses that hold up are the ones you already know. Patching faster won't keep pace; architectural resilience will.

- Design so a single compromise stays small. Segmentation, least privilege, and identity isolation keep one foothold from becoming a company-wide incident. The goal is shrinking blast radius and dwell time, not hoping the perimeter holds.

- De-risking change is a security control. Snapshots, staged rollouts, and tested recovery make patching routine instead of disruptive, and the same investments pay off against ransomware, failed upgrades, and human error. Resilience you can practice beats a plan you've never run.
