Unwanted login attempts – Protect with 24/7 SOC monitoring

Imagine this: it’s 02:47 a.m. While you sleep, someone tries to access your corporate environment unseen. No notification. No alarm. Only the next morning do you discover that someone has broken in – perhaps too late.

For many Dutch companies, this is not a fictional scenario, but daily reality. Cybercriminals choose precisely the quiet hours to strike. And yet, many organizations still rely on default notifications or basic security within Microsoft 365 or other platforms.

The problem? These detection systems are not always set up to notice suspicious activity immediately. The result: costly downtime, data breaches or even permanent reputational damage.

At ALTA-ICT, we believe that security should never sleep. That’s why our Security Operations Center (SOC) team watches live 24/7. When someone logs in unauthorized, you get a call immediately. No delays, no surprises – just security.

In this blog you will discover:

Exactly what unwanted login attempts are and how they occur.
How Dutch companies can better arm themselves against this threat.
What implementation steps are required for 24/7 monitoring.
What mistakes are often made – and how to avoid them.
How our customers realize demonstrable ROI with proactive security.

Choosing ICT partner – What really counts?

What are unwanted login attempts?

- Definition: brute force, phishing login, credential stuffing.
- Dutch context: mandatory data breach notification (72 hours), role of Personal Data Authority.

Impact: downtime costs an average of €7,500 per hour for SMEs.
Why detection often fails: standard MFA, delayed logging, lack of monitoring.
