## Imperva End-of-Life Support Policy

Imperva has established an End-of-Life Policy for all Imperva customer managed software and hardware products to deal with new software releases that are launched on a regular basis.

During its lifecycle a product will pass through the following milestones until it reaches its final End-of-Life state:

### Software

#### Life cycle milestone definitions:

- #### Release Cadence

New major version releases will be introduced when significant changes occur, such as operating system changes or infrastructure changes.

- #### Versioning

The major version is the first number in the release format. The minor version is denoted by the second digit, and the patch release is denoted by the last digits.

- #### Patch types

Public Patches include new functionalities alongside bug and vulnerability fixes. When a critical vulnerability or significant software issue is found, a Critical Patch is released.

- #### End of Life (EOL) and End of Support (EOS) Milestones

EOL defines a limited support phase before EOS. The minimum EOL period will be 1 year. EOS marks the point at which no support of any kind will be provided.

- #### Minor and Patch Version Cadence

A minor version release will receive support for at least one year from its release date.

- #### Long Term Support (LTS) Cadence

Once a minor release is declared LTS, it will be supported for a minimum of two years prior to entering the End of Life (EOL) phase.
