Companies keep bolting AI onto their products, and the security bill is coming due
Companies keep bolting AI and LLM features onto their products, and the security results are starting to show a pattern. The vulnerabilities those features create get rated high risk far more often than anything else, and they get fixed slower than anything else. The figures come from Cobalt's AI and Pentesting Pulse Report 2026, built on five years of penetration testing data and a survey of 455 security leaders and practitioners. AI applications stack new weaknesses on top of old ones. READ MORE...
