Critical cybersecurity vulnerabilities doubled in 2026, with AI speeding attacks and shrinking response time.

The 2026 Exposure Gap Report by Check Point reveals a doubling of critical cybersecurity vulnerabilities to 42.6%, driven by AI-accelerated attacks that reduce the time defenders have to respond. Despite the surge, fewer than 8% of vulnerability alerts require urgent action, highlighting the need for better prioritization. Phishing attacks also rose sharply, now making up 10.5% of critical exposures. Organizations are closing exposures effectively when prioritization workflows are in place, with some sectors resolving issues within hours. The report emphasizes shifting from detection to exposure management to stay ahead of fast-moving threats.
