Imperva products end-of-life policy

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. The introduction of major versions is not tied to a specific timeline but rather to the requirements and changes in the software.

• 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.A new major or minor version might have new features, as well as bug fixes. A new patch release typically includes bug fixes. For example, 14.2.0.xx ⇐ xx is the patch identifier.

• Patch types

  Public Patches, including new functionalities alongside bug and vulnerability fixes, are thoroughly tested before release, and users are recommended to install them on an ongoing basis for software security and functionality. When a critical vulnerability or significant software issue is found, a Critical Patch based on the latest public patch version is released and specifically tested for the scope of the discovered issue, with immediate installation recommended to ensure system integrity. Private Patches, or Debug Patches, are customized for specific issues, acting as temporary solutions or for debugging until a permanent fix is available in a Public Patch. These patches are essential for addressing particular problems and should be installed as advised.

• End of Life (EOL) and End of Support (EOS) Milestones

  EOL is the period during which a release enters a limited support phase before reaching EOS. The minimum EOL period will be 1 year. During limited support, the release will not be available for download, and private patches will be provided based on the latest available minor release or the most recent patch version. 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. After this period, it enters the End of Life (EOL) phase, followed by End of Support (EOS). Software updates may be issued for the latest minor version. The End of Life or End of Support dates will be communicated through our website. Once EOL is announced, the software will be removed and will no longer be available for download.

• Long Term Support (LTS) Cadence

  Once a minor release is declared LTS, it will enter an LTS cadence which is different from the standard minor version cadence. An LTS release will be supported for a minimum of two years prior to entering the End of Life (EOL) phase, followed by End of Support (EOS). During the lifecycle of a major version, there will be at least one LTS release. Patch versions released as part of LTS release will include bug fixes and security patches. New features will not be added to an LTS Patch version. LTS patches will be released as needed. LTS release is designed to be very stable, so there may not be a need for a regular patch cadence.

Hardware

Imperva hardware appliance models reach end of product life due to market requirements, technological innovations, or replacement by products with new, more advanced technology. Imperva reserves the right to revise the policy at any time and customers are requested to stay updated with the latest policy published in the Imperva customer support guide.

To ensure a smooth migration to new Imperva hardware platforms, Imperva will continue to support hardware based on the stated end of life milestone of sixty (60) months after the announced End of Sale date.

Accordingly, the EOL policy for Appliances is:

Milestone 1: Last Order Date (LoD)

• Last Order Date (LoD) defines the period during which customers may continue to purchase the generation of hardware appliances and its addons referenced in the LoD notification. LoD notification is provided to customers 90 days before the End Of Sale (EOS) date.

Milestone 2: End of Sale (EOS)

• This milestone marks the end of the availability for purchase of the hardware appliance and all related addons. After the EOS date, customers will no longer be able to purchase the hardware appliance or its addons.
• Imperva will continue to support a hardware appliance for sixty (60) months after its End of Sale Date.
• During that sixty (60) month period, repair services or replacement parts will be available for an Appliance pursuant to the applicable agreements.
• During that sixty (60) month period, all standard technical support services, including access to the Imperva Customer Support Portal, and to phone support, will be available to customers with existing Support Contracts.

Milestone 3: End of Software Update (EOSU)

• The EOSU milestone defines the last supported software and date for a specific hardware appliance. This final version will be specifically stated in the hardware end-of-life schedule on the Imperva website.
• The appliance will continue to support software versions released prior to the EOSU in accordance with the software end-of-life schedule.
• Between the End of Sale (EOS) and the EOSU, new software versions may be released.
• New features or software releases post-EOSU may require a hardware upgrade.
• After the EOSU, customers will continue to receive releases for the last supported software version.
• These releases will be provided in accordance with the software end-of-life schedule.

Milestone 4: End of Software Maintenance (EOSM)

• Occurs either 4 years after the Last Order Date or at the end of the support period for the latest version supported by the appliance, whichever comes first.
• Marks the end of maintenance support for the software, meaning no new patches or fixes will be released after this date.
• After EOSM, customers will still have access to basic support services. This includes assistance with usage, configuration, and troubleshooting based on the existing software and its last updates.

Milestone 5: End of Support Life (EOSL)

• This milestone marks the end of support life for the appliance.
• It is reached 5 years after EOS, and customers will no longer receive any support for the appliance after this milestone.

Note: The duration and specific milestones mentioned in this policy may be subject to change at the discretion of the vendor. It is recommended that customers regularly review Imperva customer support guide for any updates or changes to the End of Life policy for their hardware appliance.
