Current Versions of the AnyConnect Client
This page provides an overview of the most recent Cisco AnyConnect Secure Mobility Client releases, along with a short summary of the main improvements, fixes, and changes introduced in each version. Before upgrading, we recommend reviewing the release notes in detail, verifying compatibility with the operating systems in use, and ensuring support for your Cisco ASA or Secure Firewall / Secure Client infrastructure.
For production deployments, always prepare a rollback procedure, test new versions with a pilot group, and verify that critical features — such as authentication, SSO, DNS resolution, and posture checks — behave as expected. You should also validate installer hashes to ensure file integrity.
- Version 5.1.3 – Stability fixes for Always-On VPN environments, improvements to DNS resolution in hybrid networks, and updates to cryptographic libraries used for TLS tunnels.
- Version 5.1.2 – Enhanced SAML/OIDC authentication flows, UI refinements, and extended logging options to help support teams diagnose connection or posture issues.
- Version 5.1.1 – Performance improvements in the tunnel module, automatic MTU detection to reduce fragmentation, and expanded compatibility with various corporate proxy configurations.
- Version 5.1.0 – Major release: updated access policy handling, more granular user-group controls, refreshed client drivers, and an improved installer wizard with additional options for large-scale deployments.
Full details for each version — including specific fixes, known issues, and behavior changes — are available in the official release notes. After upgrading, verify SSO functionality, certificate chains, split-DNS behavior, tunnel performance, and any integrations with monitoring or security tools.
