Veza's Over Provisioned Access Score (OPAS) is a modern approach to quantify over-provisioned access and help security teams take actionable, data-driven steps to reduce risk. OPAS scores represent the percentage of access granted to an identity that has not been used recently, providing real-time insights into over-provisioning. By combining OPAS with Veza's Activity Monitoring, security teams gain near-real-time visibility into privilege usage, enabling them to identify and remove excessive permissions, streamline compliance efforts, and enforce least privilege with precision. The solution helps organizations eliminate standing privileges for inactive users and service accounts, reduce excessive access across cloud, SaaS, and on-prem platforms, and shrink the attack surface without disrupting legitimate workflows. OPAS also streamlines access reviews by displaying OPAS scores alongside entitlements, ensuring that permissions are revoked based on usage, not assumptions. By quantifying privilege risks and enabling proactive access reductions, organizations can finally take control of their attack surface and implement the principle of least privilege, significantly reducing risk without disrupting business operations.
