Enterprise Defenses Recovered at the Edge and Collapsed Inside

Enterprise defenses are tuned to catch the attacks that make noise. This year's data shows attackers winning by making none. According to Picus Labs' new Blue Report 2026, which measured more than 338 million real attack simulations across actual client production environments in the first half of 2026, defenses are having one of their strongest years yet. Average prevention effectiveness

The article reports on enterprise cybersecurity outcomes from Picus Labs’ Blue Report 2026, saying average prevention effectiveness rose to 69% across more than 338 million simulations, while logging reached a four-year high. It also says defenses are stronger at the perimeter than inside the environment, where quiet actions like reconnaissance and credential theft remain weak points. RealGround analysis: this is primarily a security posture and governance issue rather than an AI-specific attack, so the main implication is to validate internal controls, detection engineering, and control effectiveness instead of relying on boundary defenses alone.
