The Computer Emergency Response Team

CERT stands for ”Computer Emergency Response Team”, and we, the S-CERT, are the computer emergency response team of the German Sparkassen-Finanzgruppe (Savings Banks Financial Group). S-CERT consists of members drawn from savings banks, Landesbanken and insurers as well as IT service providers affiliated directly with the Sparkassen-Finanzgruppe.

S-CERT is a service of SIZ GmbH. It serves not only members of the Sparkassen-Finanzgruppe, but other German financial institutes too.

S-CERT also provides its international partners with a central point of contact with the German finance industry, and as such, forms an important first point of contact for all IT-security-related issues.

We are available for you!
