Is the trial really free for 30 days?
Yes. No credit card at signup. You get a full license, deploy it on your own infrastructure, and decide afterward.
Do I have to attend the demo to start the trial?
No - your license and download access are sent by email as soon as your request is processed. The demo call is there to help you deploy faster and answer your specific questions.
What if my provider isn't in the list?
tamper works with any storage that speaks the S3 protocol. Pick "Other" and tell us which one - we support 17 providers today and growing.
Where does my data go?
Nowhere. tamper is 100% on-premise. It connects directly to your buckets from your own servers, and logs never leave your infrastructure.
Who builds tamper?
tamper is developed by SIENNA, an infrastructure, cybersecurity, and offline storage services company based in Lille, France, helping SMBs and mid-caps elevate their cyber-resilience. The same team handles demos, deployment, maintenance, and support.
