Limitations to Consider

The free edition is limited, so it is not a basis for a compliance process
SSD erasure depends on the edition and on the drive's firmware support
Reporting is simpler than enterprise portals, so you may need extra process for audit trails
Independent certification varies by product, so check what the vendor states
You still handle collection, chain of custody and destruction of failed drives

Prefer Not to Run the Software Yourself?

If you only have occasional clearances, or want a ready-made audit trail, it is often simpler to hand the job over. We provide hard drive wiping, SSD wiping, laptop and PC wiping, server and RAID wiping and mobile and tablet wiping, with free secure collection, on-site data wiping where equipment cannot leave your site, and a data erasure certificate for every job.
