Your secrets are one
paste away from a
public AI model.
Sensitive prompts leave through ChatGPT, Claude, and Cursor. Tools your DLP, CASB, and browser controls never see. Themisto runs on every laptop and governs each AI request before it leaves the device. Engineers keep shipping. Security keeps control.
“We don't really have AI usage here.”
Governance at the only place
it can't be bypassed: the device.
AI-bound traffic on managed devices routes through the on-device agent. Every request is attributed to the originating process: chrome.exe, cursor.exe, a rogue script.
Policy is applied per process, per user, per destination model. Sanctioned tools flow. Unsanctioned tools alert or block. Your call, enforced in milliseconds.
Secrets, credentials, PII, and source code are detected by smart AI classification and stopped before egress. The leak never happens, and the audit trail proves it.
Be the employee.
Watch it decide.
Smart AI detection reads intent and content, not just keywords, and acts before a single byte leaves the laptop.
Everything security needs.
Nothing engineers notice.
PII, credentials, secrets, and source code detected by smart AI classification in the prompt itself, before egress. Intent-aware detection built for how people actually paste.
Certificate-based identity between agent and gateway. Lost or offboarded laptop? Revoke the device in one click and it goes dark.
Approve Copilot, alert on random AI wrappers, block the sketchy ones. Per-tool, per-team, per-policy.
Every request mapped to the binary that made it. Browser, IDE, script: you'll know.
Every decision recorded with full context. Built for compliance reviews and incident response.
Employees, devices, tools, destinations. One dashboard over your whole AI surface.
Update policy once; every agent pulls it automatically. No re-imaging, no truck rolls.
Windows & macOS installers, Chrome & Firefox enterprise deployment, offboarding flows.
Browser extensions watch a window.
We govern the machine.

Asked constantly. Answered straight.
[+][-]How can I see which AI tools my employees are actually using?
Not from the firewall, that much we can tell you. Logs show domains, not usage, and surveys just measure honesty. The only place you can really see it is the work laptop itself, where the request starts. That's where Themisto sits. Work devices only, we never touch personal phones, and every AI request gets pinned to the app and the person it came from. You end up with a real inventory instead of a guess.
[+][-]What is shadow AI?
All the AI your company never approved: someone's personal ChatGPT account, a free chatbot they found last week, an AI extension in their browser, a coding assistant on a personal license. Microsoft and LinkedIn found 78% of people using AI at work bring their own tools. The tools aren't the problem. The problem is company data flowing through them under terms nobody read.
[+][-]Does blocking ChatGPT at the firewall stop employees from using AI?
It stops the traffic on your network, sure. The usage just moves to phones and hotspots, where nobody can see anything at all. KPMG found 57% of employees already hide their AI use from their employer, and a ban hands the rest a reason to start. What holds up is handling it on the work device itself: approved tools go through, risky pastes get stopped, and you can always see what happened.
[+][-]How is Themisto different from DLP or a CASB?
DLP watches files and email. A CASB watches your sanctioned SaaS. An AI leak is neither. It's 300 words pasted into a chat box, encrypted and gone in about two seconds. Themisto catches it on the device before it leaves, knows exactly which app sent it, and decides in milliseconds. Works the same whether the laptop is in the office or in an airport.
[+][-]What does the free 7 day AI audit include?
We put Themisto on up to 10 of your machines for 7 days. Nothing changes for the people using them. At the end you get the full picture: which AI tools are in use, how much, from which devices, and what nearly left. Then you decide. If it wasn't useful, we uninstall and part friends.
