NEW YORK — What happened: Recent penetration testing benchmarks published in September 2026 show that over half of enterprise Zero Trust network architectures can be bypassed due to misconfigured identity and access management (IAM) tokens. Despite heavy corporate investment in perimeter-less security, attackers are successfully hijacking session tokens to move laterally across corporate networks.
Why it matters: Zero Trust relies entirely on the premise that no user or device is trusted by default, requiring continuous verification. However, if the underlying identity provider accepts compromised credentials or issues overly permissive session tokens without adequate hardware binding, the entire security model collapses into a false sense of safety.
Deep dive: The core failure stems from legacy enterprise applications that cannot natively handle modern token-revocation signals. When an employee's device is flagged for suspicious behavior, the identity provider might revoke access at the gateway, but the backend application often continues to honor cached session tokens for hours or even days, allowing persistent unauthorized access.
Report check (claims vs what is verified vs still rumor): Security researchers claim that 55 percent of enterprise IAM setups lack proper token lifecycle controls. While major identity vendors dispute this specific percentage, enterprise security logs consistently show session hijacking as a primary vector in recent high-profile breaches.
Open questions: Can legacy enterprise software be retrofitted to support real-time token revocation, or must organizations accept the risk until those applications are completely rewritten?
