Every security product ever built was designed to keep someone out. Blackout was built for when the adversary already has the keys — authenticated, credentialed, invited in, paying them monthly. Blackout OS is the platform that sits between your organization and every vendor in your stack, observing what they actually do with the access you gave them.
Blackout OS gives you a single dashboard for every vendor in your stack — what they're running, what they're accessing, what they're not telling you, and what it costs.
Scan your site and every vendor shows up — risk scored, consent tested, supply chain mapped. Connect your accounts and see what they do from the inside.
600+ vendor signatures. 3-pass consent testing. Pre-consent, post-accept, post-reject.
Connect a vendor account and Blackout observes every outbound API call, every third-party dependency, every undisclosed data flow. Classified automatically: expected, known, undocumented, exfiltration.
Your credentials. Your account. Metadata only — we observe network behavior, never read your business data.

Vendors update their code without telling you. New scripts appear. Data flows shift. Blackout detects every change and alerts you with context: what changed, when, and whether it's documented.
Drift detection across every scan. Behavioral baselines per vendor. Alerts on anomalies.
Not a risk score. Not a severity rating. A number your CFO understands. Data in vs. data out. Contract terms vs. observed behavior. Revenue impact.
Upload your vendor contracts. Blackout cross-references what they're allowed to do against what they actually do. The delta is the finding.
