Understanding Enterprise Security Risks
In 2025, organizations faced 48,512 vulnerabilities, a 43% increase from the previous year, with more than 130 new CVEs reported daily. The greatest risks came from a smaller group that targeted critical enterprise systems such as identity platforms, VPNs, collaboration tools, ERP applications, and cloud environments.
Many of these CVEs made it possible for attackers to take advantage of trusted systems and navigate networks with minimal visibility by enabling authentication bypass, session hijacking, or pre-authentication compromise.
This whitepaper examines the 10 CVEs that had the greatest enterprise impact in 2025, and the attack patterns organizations must prepare for in 2026.
In this whitepaper, you will learn:
- The top ten CVEs that had a major effect on businesses in 2025
- How attackers exploited identity systems, VPNs, and trusted services
- Why perimeter defenses and MFA are often bypassed
- The growing risk of session hijacking and authentication bypass
- Why east-west and encrypted traffic create major visibility gaps
- Key security priorities organizations should adopt for 2026
