For restricted environments

PDF redaction for air-gapped and offline networks

Some networks never touch the internet — defence programs, courts, investigations, protected health systems. Many online redaction tools need a server. Omitly's redaction does not.

Built to work disconnected

Installs offline

On macOS, the signed, notarised installer carries across on your approved media and installs without a connection. On Windows, the installer needs the Microsoft Edge WebView2 Runtime: Windows 11 includes it. Older Windows 10, and any LTSC, Server or locked-down image without it, must have WebView2 installed before you cross the gap; otherwise the installer tries to download it. No account creation, no activation server.

Runs offline

Your licence is a file, not a phone-home check. Redaction, sealing and verification work fully offline; an RFC 3161 timestamp is opt-in, off by default, and needs a connection to a timestamp authority.

Verifies offline

Anyone with the Omitly desktop app can verify a sealed PDF offline, free and with no licence — the seal carries what the verifier needs.

Why cloud redaction can't follow you in

Upload-based tools are a non-starter on a segregated network — and a hidden dependency everywhere else. If your redaction tool needs someone else's server, your most sensitive workflow has an internet dependency and a third party in it by design.

Updates on your schedule

Releases ship as signed installers you can bring across the gap through your own change process. Nothing forces an online update, and no feature quietly stops working because a server went away.

Redaction that respects the gap

One installer and one licence file. Redaction needs no cloud.
