End of Life Policy for Cato Clients

  • Updated

This article discusses the support policy for Cato Clients that are defined as End of Life (EoL).

Overview of the Cato Client End of Life (EoL) Policy

Cato Networks supports multiple versions of the Cato Client for each operating system. At some point, new features and security updates for the newest Client are incompatible with an older version and that version is declared as EoL. In addition, when a vendor announces that an operating system is declared EoL, for example iOS version 4.0, Cato will announce when the hosts or devices that are still using that version are End of Support (EoS) for the Client.

When a Client is EoL or an operating system is EoS, Cato no longer supports it and customers can't open tickets for issues with the Client. If you are using a version that is EoL, we strongly recommend that you immediately upgrade to the newest version.

Note: An EoL announcement can include multiple Client versions and operating systems. Cato will also send reminders about upcoming EoLs before the final EoL date.

End of Life (EoL) Policy for the Cato Clients

When Cato plans that a Client version for a specific operating system is EoL, an email notification is sent to customers six months before the EoL date. However, if there's a critical issue with an older Client version, the EoL date can be shorter than six months. After the EoL date, Cato doesn't support that version and customers must upgrade the Client before they can contact Support. There is a brief grace period when users can continue to use the old Client version to connect to the Cato Cloud. After the grace period is over, Clients using this EoL version can't connect to the Cato Cloud.

For example, on February 1st, Cato announces that Android version 2.3 will be EoL on August 1st and sends email notifications to customers. On August 1st, Android version 2.3 is officially EoL and customers can't open Support tickets for this Client version. After about one month, the grace period for Android version 2.3 ends and end users with this version can't connect to the Cato Cloud.

We recommend that all end users upgrade a Client that will soon be EoL before the actual EoL date.

End of Service (EoS) Policy for Operating Systems

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

For example, Apple announced that the EoL for OS X 10.11 (El Capitan) was EoL on September 2018. In January 2019, Cato announces that the EoS for Clients that are installed on hosts with OS X 10.11 is June 2019.

End-of-Life (EoL) Client Versions

To improve security and to support recent and upcoming capabilities, the following Cato Client versions are end-of-life and no longer supported:

  • Windows: 2.1.1.0

    • As of Windows Client 4.5, Cato no longer supports installing the Client on Windows 7

  • macOS: 2.3.0

  • iOS: 1.7.0

  • Android: 2.2.1

  • Linux: 1.2.4.137

    • As of January 1, 2022, Ubuntu 14 is no longer supported

VPN users with these Clients can't log in until the Client is upgraded. We continue to support all Cato Client versions that are newer than these versions.
