Why data masking matters
Regulation tightens, multiplies the risks.
Sirius shrinks what's exposed, so a stolen query, a leaked backup, or data fed to an AI tool reveals masked, useless values, with the audit evidence regulators expect.
“Every field you leave unmasked is a breach you simply haven't had yet. Plain-text data isn't an asset. It's a liability with your customers' names on it.”
Gartner predicts 50% of organizations will adopt a zero-trust posture for data governance by 2028. Sirius gets you there today: mask by default, reveal only by policy, and hand attackers nothing worth stealing.

The business case
One insider. 200,000 records.
A real 2025 incident at a major fortune 100 institution. Here is the exposure, and what masking at the source would have changed.

Former employee was all it took: no outside hacker. Per-user masking caps even trusted insiders at exactly what they are authorized to see.
Inside job4 days
From dark-web listing to sold. Masking renders a stolen copy worthless, so how fast it leaks stops mattering.

One console, total control
Define a policy once. Enforce it everywhere.
Sirius sits as a transparent proxy in front of your data sources. Every read is inspected, masked and logged in real time. It's all managed visually, with no SDKs and no rewrites.
Dynamic masking, applied live
Edit a policy in the console and it takes effect on the next execution. No server restart, no redeploy, no app change.
Write protection
Protected fields can't be quietly overwritten through the proxy. Updates leave them untouched.
Discovery & audit
Auto-classify PII, PHI and cardholder data, and log every access into a tamper-evident trail.
Stop storing risk. Start masking it.
