Piiano Vault affords knowledge safety for delicate private data. With automated compliance controls, it lets you retailer delicate private knowledge in your personal cloud surroundings.

Piiano Vault might be put in inside your system, alongside different databases utilized by the apps. It needs to be used to retailer probably the most delicate private knowledge, akin to bank cards and checking account numbers, names, emails, nationwide IDs (e.g., SSNs), and so on.

The first advantages are:

Dusk

With Dusk customers can uncover what lives at relaxation in your knowledge silos. Dusk scans directories, exports, and backups for delicate knowledge (akin to PII and API keys) utilizing Dusk’s knowledge loss prevention (DLP) APIs. directories. Dusk makes use of machine studying to detect PII, credentials, and secrets and techniques.
