Important Notice: Retirement of Legacy CTI Cloud Endpoints for Zenarmor Versions

[beki]

Dear Zenarmor Community,

To ensure the highest level of network security, performance, and system stability, legacy CTI cloud endpoints serving Zenarmor versions prior to 2.1 will be permanently turned off on October 31, 2026. Systems running pre-2.1 builds will no longer fetch live web categorizations, malware feeds, or real-time domain lookups.

Clarification on Version Support

Please note that versions prior to 2.1 are already out of official support. For instance, on platforms like OPNsense, Zenarmor officially supports only the last two major releases. While CTI cloud lookup services have continued to work on these older builds up until now, those legacy CTI endpoints will be permanently decommissioned at the end of October.

Why You Should Always Run the Latest Version
Running the latest version of Zenarmor isn't just about maintaining connectivity—it is a very important way to protect your network properly. Upgrading to the latest release ensures you benefit from:

• Enhanced Security: Access to our newest machine-learning classification models and immediate protection against emerging zero-day exploits.
• Superior Performance: Ongoing engine optimizations that reduce CPU and memory footprints.
• New Features & Bug Fixes: Immediate access to new dashboard tools, advanced policy controls, and system stability updates.

Impact on Legacy Versions (< 2.1) After October 31, 2026

If your firewall or gateway is still running a pre-2.1 engine after October 31, 2026:

• CTI Cloud Disconnection: Your engine will no longer be able to query Zenarmor cloud threat servers.
• Incomplete Threat Protection: Real-time domain lookups, dynamic malware blocklists, and advanced web categorizations will stop functioning.

Required Action: Upgrade to the latest Zenarmor version

We strongly encourage all users running older builds to update to the latest Zenarmor release well ahead of the deadline.

If you have questions, run into dependency issues during the upgrade, or need technical assistance,  open a ticket through the application or reach out directly to our support team at support@zenarmor.com.

Thank you for your cooperation as we work to keep your networks secure!
