Stop sensitive data walking out through AI tools.

Four detection layers, one moment

Credentials are matched against known secret formats (API keys, tokens, private keys), so they're blocked outright, with no override available. Contract and policy terms are matched against documents you upload, so Alesia recognizes your specific confidentiality language instead of a generic keyword list. Files and screenshots are scanned for embedded sensitive content before they're attached to a prompt. Confidential documents are matched by fingerprint against your internal repository, so a leaked draft is caught even after the wording has been edited or reformatted. None of these checks depend on the employee remembering a rule or reading a policy document first: the same four layers run automatically on every prompt, on every device, the moment text is about to be sent.

A pasted contract, caught before it's sent

An account manager is troubleshooting a pricing question and pastes a full client agreement into an AI chat tool to ask which clause applies. Alesia recognizes the document against your uploaded contract set, blocks the paste, and suggests copying only the relevant clause instead. The manager gets an answer within a few seconds; the client's full agreement never reaches the model provider's servers, and the organization sees a blocked event tagged 'confidential document,' never the contract text itself. The manager's team lead later sees, in the weekly summary, that this kind of block happens a few times a month for account managers specifically, a signal that maybe a redacted contract-summary template would save everyone the trip.

What changes for your team

Leak prevention stops depending on employees remembering the rules on their own. None of this requires employees to learn new tools or workflows. The protection runs quietly underneath whatever AI chat product they already use. And because detection runs locally, it keeps working even for devices that are only occasionally connected to your corporate network.

• Credentials are blocked outright, no exceptions to manage
• Contract language is recognized, not just keyword-matched
• Blocked and overridden events are logged with a reason
• New sensitive documents can be added without a rebuild
• Works the same across browser, IDE, and CLI surfaces
