Infrastructure & engineering

Your IT
run by
engineers.

We operate your infrastructure under contract: monitoring, updates, maintenance and support for your teams, with response times defined in writing.

No commitment · Everything under NDA from the first message

Sound familiar?

IT shouldn’t be
your problem.

It should work, be up to date and be secure, without taking up your time or your team’s.

Updates are waiting

Nobody has time to apply them. Known vulnerabilities stay open for months.

Support depends on one person

When they’re away, everything stops. And what they know isn’t written down anywhere.

Your users find the failures first

A full disk, a stopped service: you find out when someone complains.

Your provider doesn’t think security

They fix things, but nobody checks that the whole stays protected.

What we do

Operate, maintain,
support.

Full management, designed by a cybersecurity firm.

Monitoring

Problems caught before your users notice

Why Security255

Systems engineers
who think like attackers.

Over 23 years on Linux

Systems engineering is where we come from. We don’t discover your systems — we know them from the inside.

Open source and sovereignty

Open, auditable and long-lasting technologies. Your infrastructure doesn’t depend on a vendor’s commercial policy.

Security first

We are a cybersecurity firm. Segmentation, encryption and access control are part of the project, not an option.

Hardware supply: we specify, supply and integrate the hardware required as part of the project.
