Emergency

An incident
in progress?
We step in.

Ransomware, data leak, unauthorised access. We contain the attack, analyse what happened and get you back up and running as fast as possible, preserving the evidence.

No commitment · Everything under NDA from the first message

Sound familiar?

The first hours
decide everything.

Every minute counts, and the wrong reflexes can make things worse or destroy evidence.

Your files are encrypted

A ransom note appears, the business stops. You don’t know how far the attack has spread.

An account has been compromised

Emails go out in your name, suspicious transfers appear, unknown logins connect.

Data may have leaked

You need to know what, how and when — and possibly report it within legal deadlines.

You don’t know who to call

Your usual IT provider isn’t equipped for a security incident, and time is running out.

What we do

Contain, understand,
recover.

A response led by experts used to real crisis situations.
