Here you find all IGEL Security Notices (ISNs). They inform you of any major vulnerabilities that have been found in IGEL software products and of how to fix or mitigate these. If you have questions or concerns about ISNs, you can contact the IGEL Security Team at If you are an IGEL customer, please open a case on the IGEL Customer Portal.

Besides that, most IGEL software updates fix several minor vulnerabilities. You find information about these in the Release Notes that are published with each release.
