Cybersecurity

Someone is watching
while
you sleep.

We monitor your infrastructure continuously, detect threats before they become incidents and act without waiting for your call. You get results, not alerts to decode.

No commitment · Everything under NDA from the first message

Sound familiar?

An attack gives no warning.
It settles in.

Most intrusions go unnoticed for weeks. The problem isn’t having tools — it’s having someone who actually looks.

Nobody watches the alerts

Your systems produce logs and alerts. Nobody has time to read them, let alone interpret them.

You find out too late

A compromised account, a server behaving oddly: too often it’s noticed once the damage is done.

Your IT team is already stretched

They maintain, fix and deploy. Security monitoring always comes after the urgency of the day.

You don’t know where you stand

Without clear indicators, you can’t tell management whether the company is better protected than six months ago.

What we do

Monitor, detect,
act.

A complete service, run by senior engineers, tailored to your actual infrastructure.

01
Monitoring

A permanent view of what’s happening

Collection and analysis of events from your servers, workstations, network and online services. What’s abnormal surfaces, the noise is filtered out.

Our method

Up and running in days,
not months.

01

Scoping

We identify what must be monitored first: critical assets, sensitive access, internet exposure.

02

Deployment

We set up collection and detection rules without disrupting your business.

03

Tuning

In the first weeks we refine the rules so only useful alerts remain.

04

Active monitoring

We watch, we act and we report to you every month.

What you get

What you get.
Not another piece of software.

Analysts, not a robot

Every significant alert is reviewed by a person on the team.

Written procedures

What we do during an incident is defined and approved with you in advance.

Real visibility
