Built for the admin who is also the security team.
Every tool a company already pays for watches the network, the mailbox or the files sitting in Drive. The paste into a tab is the one hop nobody is looking at — and it is the one your team does forty times a day without thinking. Capsulla exists for that hop, and for nothing else.
Nobody involved is doing anything wrong
The engineer pasting a config into an assistant is trying to fix a deploy. The support agent pasting an order is trying to answer faster. Treating that as an insider threat is both wrong and useless — what an admin actually needs is to see it happening, decide what matters, and put a stop to the few things that do.
Three decisions we made early and will not revisit
The matching happens on the device, so your text is never collected to be judged. Detection uses no model — patterns, checksums, file types and domains, things you can read and argue with. And there is no agent, no proxy, no certificate and no second browser: it is an extension and a console, or it is not worth deploying.
The people behind Locki
Capsulla comes from the team that built Locki, encryption for team communication in the browser — same kind of company, same kind of admin, the same stubbornness about keeping data on the device. A small team is also why this product is narrow and the price is one number rather than a quote.

You can read what Capsulla cannot do before you talk to anyone: it is Chrome only, managed browsers only, and it will not see data already sitting in your SaaS. Nothing here needs a discovery call, and the trial does not need a card.
