After purchasing a specific edition of Cerberus FTP Server, users will be emailed a license code that can be used to turn the trial version of Cerberus FTP Server into a fully licensed and functional Standard, Professional, or Enterprise edition. No new installation is necessary. Each license includes a 1 year Service Agreement that entitles the purchaser to upgrades and support for 1 year from the purchase date. The license code will work with any version of Cerberus released within one year of the purchase date of the license.
Service Agreement options are also available that provide a license code that will work on any version of Cerberus FTP Server for more than 1 year of the license purchase date. These are available at a discounted annual rate. Ask Cerberus Sales about a quote for a multi year support contract.
Note: The software itself never expires, just the ability to update to the latest version expires. When your support period is over you can purchase a new support agreement if you wish to continue receiving support and updates.
