What’s in this release?


New features, enhancements, and other improvements 

Now in public preview: Continuous Identity Security featuring Duo Identity Security

Our integration with Cisco Identity Intelligence adds value on top of your identity and security investments like Microsoft Entra and Okta. It uses AI to analyze all identity-related activity across all accounts, all devices and IdPs to provide deep visibility into identity infrastructure and continuously inform Cisco Duo enforcement points.


Duo policy default updates for customers with Duo Advantage and Duo Premier editions


LastPass is now compatible with the Duo Universal Prompt

  • The Duo-protected LastPass application will now show that it is Ready to Activate in the Duo Admin Panel after you authenticate to LastPass with the "Use Duo Web SDK when possible" option enabled in your LastPass Duo multifactor settings.


New location for What's New content in the Duo Admin Panel

  • What’s New content has been relocated from the Dashboard to the Help menu, where it offers better navigation experience and is accessible from every page in the Duo Admin Panel.


Improvements to enrollment in the Duo Universal Prompt

  • Updated content to provide clearer instructions to enrolling users.

New and updated applications

Six new named SAML applications with Duo Single Sign-On


Duo Multifactor Authentication for Cisco ISE


Duo Authentication Proxy version 6.4.0 and version 6.4.1 released

  • Version 6.4.0
    • Fixes unnecessarily strict Connectivity Tool validation of ldap_server_auto SSL certificates.
    • Improves logged error messaging for AD DIR_ERROR responses.
    • The Authentication Proxy Manager now displays additional error information in certain failure scenarios.
    • Updates the internal build process to use scoped package names.
    • Upgrade to Cryptography 42.0.5 / OpenSSL 3.2.1 to address CVE-2024-26130, CVE-2023-50782, and CVE-2024-0727.
      • This version of OpenSSL changes the default SSL/TLS security level from 1 to 2. As a result of the default security level change, certificates with key lengths less than 2048 are no longer acceptable for inbound and outbound SSL, LDAPS, or STARTTLS connections to the Authentication Proxy. Our recommendation is that you reissue your certificates with key lengths of 2048 or greater. If you cannot update your certificates now, a workaround is available. Please see Duo KB article 8866 for details.
    • Upgrade Python to 3.11.9 to address CVE-2023-6597 and CVE-2024-0450.
    • Upgrade OpenSSL FIPS module to 3.0.9 to address CVE-2023-1255.
    • Updates various internal dependencies.
  • Version 6.4.1
    • Fixes a resource leak related to failed TLS connections in ldap_server_auto.
    • Please review the information in the 6.4.0 release note. If you experience issues with LDAPS/STARTTLS connections after installing 6.4.1, and your certificate(s) have key lengths less than 2048, see Duo KB article 8866 for a workaround.
