Trend Micro said it has updated its InterScan Gateway Security Appliance line with filtering, using its "in-the-cloud" reputation services to identify dangerous websites and email sources.
The InterScan Gateway Security Appliance sits behind an existing firewall or virtual private network (VPN) solution, providing an additional layer to internet gateway security, to filters URLs and spam, viruses and spyware.
Trend Micro is bolstering this defence with its reputation services, which identify malicious websites and sources of spam. The Trend Micro Web reputation technology works by assigning websites a "reputation" based on an assessment of the trustworthiness of a website or URL, derived from an analysis of the internet domain.
Websites that come and go at a very fast rate, for example, are probably involved in activities associated with botnets or spam, and InterScan users have the option of filtering this content out.
"These reputation services are done in Trend's data centres," said Bill Hansy, Trend Micro's product marketing manager.
Trend Micro claims this service protects against web-based threats including zero-day attacks, before they reach the network.
InterScan Gateway Security Appliance, which supports Trend Micro's reputation services, is available in eight models.
