Contacting the SFO securely

We use Egress email encryption software to securely share confidential information by email and send and receive large files.

Sending encrypted emails and large files with Egress is as easy as sending a conventional email.

We will always send confidential or sensitive material to you using Egress. This is to protect you, the information being sent and the cases we are working on.

Egress is certified by the NCSC.

If you are a victim or witness, Egress will help protect your identity and conversations you have with the SFO.

If you an organisation or person required to provide the SFO with evidence or information, you must use Egress. This is so the evidence and information is protected from the moment you send the email, to the point at which it is received by the SFO.
