Security Information and Event Management (SIEM)

SIEM (Security Information and Event Management) is one of the central components of a SOC (Security Operation Center). It collects event log data from various sources such as operating systems, network components, applications and IT security tools at a central location and evaluates this automatically based on predefined rules (SIEM use cases). Depending on the data collected and the defined use cases, cyber attacks and compliance breaches can be detected almost in real time with the help of a SIEM.

SIEM is much more than a product.

In our view, SIEM is much more than just a product.

A SIEM product supports cyber defense analysts in detecting cyber attacks and compliance violations. A SIEM is useless without cyber defense analysts!

Conversely, it is essential both to feed the right data into a SIEM system and to ask the right questions of this data (SIEM use cases). If this does not happen, your SIEM will not detect cyber attacks or compliance breaches.

Our aim is for you to generate added value from your SIEM.
