All Barracuda Web Filters, and Web Security Flex utilizing the Web Security Agent.


This issue is due to a well-known incompatibility between non-IFS Layered Service Providers (like the Web Security Agent is using for traffic interception) and recent .NET Framework updates.


Microsoft has put out a fixed .NET 4.5.2 version, which fixes this issue. Please upgrade to this version.
