Managed SIEM

Blind spot in the network?

An attack is often not discovered until 100+ days later. Without centralized log monitoring, phishing and vulnerabilities remain invisible—an existential risk to DORA compliance and your bottom line.

Managed SIEM

The central monitoring platform that correlates your log data in real time, stores it in an audit-proof manner, and lets experts analyze it.

For decision-makers who want compliance and early attack detection instead of data chaos.

Managed SIEM closes the monitoring gap left open by firewalls and antivirus programs. The application correlates log data across all devices and services, making even complex attack patterns such as phishing or misconfigurations immediately visible. Centralized, tamper-proof log management prevents attackers from erasing their tracks after a breach. As a result, the system delivers not only technical security for IT managers, but also the necessary evidence for C-suite topics such as BaFin audits, DORA reporting obligations, and GDPR requirements.
