You Decide What AI Can Do with Your Data, We Enforce It Automatically

Theodosian finds every sensitive file, stops people and AI from misusing them, and gives your auditors the proof.

One Prompt Can Pull Up Everyone's Salary

That's because assistants and agents work through your people's logins and permissions, most of which were set up years before anyone thought about AI. The same prompt can reach client folders, deal files, and engineering drawings.

Your team is also uploading client files to chatbots nobody approved, not out of malice, but because that's how work gets done now.

Employees Sent Nearly Twice as Much Data to AI Tools in 2025

Enterprise data sent to AI apps rose 93% in a year, to more than 18,000 terabytes (Zscaler ThreatLabz, 2026). Every upload is a decision about your data, and today the person at the keyboard makes it, not your company's policies.

Only 11% of Organizations Actually Enforce Their AI Policies

Nearly half are still building their AI governance programs, and 17% say they're entirely unprepared (Netwrix, 2026).

Two-Thirds of Office Workers Admit to Using AI They Knew Was Banned

Blocking AI isn't the answer, because bans just get routed around (PagerDuty, 2026). You need a way to adopt AI on your terms, securely, with policies that are actually enforced.

The Market Sells Visibility, Theodosian Gives You Control

Discovery tools tell you where your sensitive data is exposed, but the report lands on Monday and the upload to an unapproved AI tool went through on Friday. A report about your exposure is not a reduction of your exposure.

Theodosian acts before the upload, not after the report. It has context on every sensitive file and decides, at the moment of access, whether a person or an AI can upload, download, open, share or modify a file.

Discover & Classify
Continuous, automatic discovery across your cloud data stores (ex. SharePoint, Google Drive, Box, Dropbox); Every file inventoried and labeled: what it contains, where it lives, and which people and AI can reach them.
Protect & Control
Labels drive policy automatically. Set a rule once and it covers every matching file, for both people and AI. The files that must never leak are encrypted automatically so a stolen copy is useless. Test it in simulation mode before turning on enforcement.
Govern & Audit
Every action across all of your data stores are recorded, whether a person or an agent took it, in a log your auditors can verify themselves. Audit prep that took weeks takes minutes.

Built for Organizations Where Security Isn't Optional

For industries handling sensitive or regulated data, such as in defense and aerospace, financial services, legal, life sciences and health, and advanced manufacturing, a single leaked file can cost the contract, the operating license, or the company.

See It in 30 Minutes. Prove It in Two Weeks.

Start with a guided walkthrough. If it holds up, we connect read-only and show you your exposure within days. Test any rule in simulation before it blocks anything to ensure it does not interrupt normal workflow. By day fourteen of the POC, enforcement is live on your own files, with an audit trail you can put in front of your board. No rip-and-replace, no services project.
