Trust no one

How many servers, firewalls, services and people do you need to trust...


Having trust issues keeps your passwords secure.


No one who's selling security software will tell you this. All software and hardware have currently active exploitable security vulnerabilities. And even if you have an application that is secure, your data can still be stolen, because there are just too many pieces involved.

There are new flaws in the underlying OS or virtualization discovered every day.

Your network equipment like firewalls, routers and switches from various manufactures may have issues right now.

How many administrators patch and update your systems? How many have made a mistake with one of the zillion configuration possibilities?

What happens if one of your administrators goes rogue?

Psono keeps the necessary trust to a minimum.

100% Server Trust

Application and Database servers hold no sensitive unencrypted data.

100% Administrator Trust

Administrators do not have and will never have access to any unencrypted data.

100% Network Trust

True end-to-end encryption makes network / infrastructure trust irrelevant

100% Application Trust

The server application has no access to any unencrypted sensitive data.

without which we never would have made it.
