SerNet integrates a variety of content filters from different vendors and providers to protect and control data traffic between the Internet and web browsers.
SAVAPI Web Gateway
SerNet integrates AVIRA's SAVAPI malware scan engine. All HTTP requests from a Browser are checked on a proxy server und blocked if potentially malicious. More and more web sites only offer encrypted sessions via HTTPS - but attacks with malware from unencrypted HTTP sites are a common threat, so the AVIRA scanner still provides important filtering.
SerNet subscribes the official list of youth-inappropriate content by the German government (BPjM, Bundesprüfstelle für jugendgefährdende Medien) and puts this list into proxy servers upon customer request. Companies using this content filter set are in compliance with an important requirement not to allow minors like interns or apprentices to encounter youth-inappropriate internet content.
Cisco Web Security Appliance
Cisco offers a variety of content filters in hardware and software appliances. Some of them enable the interception of HTTPS encrypted sessions. Because this also qualifies a system administrator to interfere with online banking or e-commerce shops every institution needs careful written user directives and user acknowledgement.
