What is the difference between the perpetual and subscription license options?

With the release of OSForensics V8, PassMark has introduced a subscription option. The licensing option best suited to you will depend on your use case, how frequently you use the software and your need to access the latest updates and user support. See below for each license inclusions.


An OSForensics monthly or annual SUBSCRIPTION license includes:


  • Access to the latest version of OSForensics
  • Continual access to major and minor release updates
  • Continual access to priority support and customer service
  • If your subscription is cancelled or expires without renewal, OSForensics will no longer work

An OSForensics PERPETUAL license includes:


  • Non-expiring license of the OSForensics version you purchased
  • Capped 12 or 36 months of support and maintenance
  • If your support license expires, OSForensics will continue to work, but you will no longer receive new version upgrades or technical support

We also offer a complimentary 30-Day Trial Edition for download. This free trial is feature-restricted and will stop working after 30 days from installation.
