EoS Policy for Cato Clients

Cato Networks maintains supported Cato Client versions to provide customers with the newest features, security updates, vulnerability mitigations, bug fixes, and compatibility with the Cato platform. As the Client evolves, older versions may no longer support the security and platform updates required to maintain a secure and reliable connection.

Each Client version has a defined support period and reaches End of Support (EoS) based on its release date. When a Client version is EoS, Cato no longer provides technical support, bug fixes, or security updates for that version, and customers can't open support tickets for issues specific to that Client version.

In addition, when an operating system vendor declares an operating system End of Life (EoL), the operating system no longer receives security patches or maintenance updates from the vendor. To help maintain a secure environment, Cato may also declare the Cato Client running on that operating system as EoS.

To maintain the latest security protections, platform compatibility, and support coverage, we strongly recommend upgrading to a supported Client version before the EoS date.

For more information about EoS for specific Clients see below. For more Supported Cato Client Versions.

When Cato plans that a Client version for a specific operating system is EoS, an email notification is sent to customers six months before the EoS date. However, if there's a critical issue with an older Client version, the EoS date can be shorter than six months. After the EoS date, Cato doesn't support that version and customers must upgrade the Client before they can contact Support.

For example, on February 1st, Cato announces that Android version 2.3 will be EoS on August 1st and sends email notifications to customers. On August 1st, Android version 2.3 is officially EoS, and customers can't open Support tickets for this Client version.

We recommend that all customers upgrade users who are using Client versions that will soon be EoS before the actual EoS date.

For a list of supported Client versions per device OS, see Supported Cato Client Versions.

For operating systems that are end of life (EoL), Cato will announce the EoS for that operating system 6 months in advance. After the EoL date for the operating system, customers can't open tickets for Clients on hosts and devices that use this EoL version.

For example, Apple announced that the EoL for OS X 10.11 (El Capitan) was EoL on September 2022. In January 2023, Cato announced that the EoS for Clients that are installed on hosts with OS X 10.11 is June 2023.
