True Zero-trust technology

At its core

Tamper-proof, decentralized software-infrastructure, that automates cryptographic-key-management, without compromising security.

It’s time for a different approach

Over $100B invested in cybersecurity, yet privacy breaches soared to over 4.1B records compromised in just 6 months, resulting in $2 Trillion losses in 2020. Accepting & protecting vulnerabilities has proved futile.

A new digital custody solution

At the end of every mass data breach, there’s a compromised key with a lot of privileges. Tide acts as an external custodian of all sensitive keys, with no need to trust a middle man.

Not just privacy protection

The same mechanism guaranteeing privacy, is just as effective for inter-corporate data exchange, devops, or any other digital ownership / access scenario.

Most cybersecurity solutions are based on a false and outdated premise:
“There’s no one better to trust your keys with than yourself.”
But you become the vulnerability exploited.

You no longer need to be a vulnerability
