The experts in Anti-Virus, Malware Protection and Anti-Spam

Utilising security integration partner technology, Tesserent takes a multi layered and multi-engine approach:

  • Kaspersky Lab mail security suite including anti-malware, content filtering and spam-fighting features – including reputation filtering and enforced anti-spam updates service
  • ClamAV antivirus engine designed for detecting Trojans, viruses, malware and other malicious threats. A de facto standard for mail gateway scanning, it provides a high performance mutli-threaded scanning daemon, tools for on demand file scanning, and automatic signature updates.
  • Commtouch’s anti-spam engine, based on their patented Recurrent Pattern Detection (RPD) which blocks spam based on its fundamental characteristics – its mass distribution and repeating patterns.
