Our appliance uses three different manufacturers to provide a multi-layered, multi-engine approach:
- Award winning Kaspersky Labs
- Clam AVG designed especially for e-mail scanning on mail gateways.
- Just-In-Time (JIT) Anti-Malware technology engine.
These engines transparently analyse all email types (both incoming and outgoing), http and ftp protocols for signs of infection and blocks viruses, worms, Trojans and malicious content at the front door. Even attachments such as .exe and .zip files are scanned. In fact, more than 670 different compression and encoding formats are decoded and scanned. Additionally, external emails from POP3 and IMAP accounts are scanned to ensure that the network is kept safe
Moreover, just-in-time technology allows to apply temporary blocks to as yet unknown viral threats until more permanent solutions have been tested and made available.
Updated in real-time using high speed PUSH technology, each appliance contains a comprehensive signature database of over 5,000,000 signatures identifying and blocking viruses, worms, spyware, Trojans and general malware threats.
For new and emerging threats, the state-of-the-art heuristic analyser uses both cryptanalysis and statistical analysis techniques to block even previously unknown viruses and worms.
- Detection of viruses, worms and Trojans from HTTP, FTP, SMTP, POP3 and IMAP4 sources.
- Incoming and outgoing message protection, with support for large email sizes.
- Support for archived attachments protects against buried threats.
- Security-hardened services, with open-relay protection prevents spread and significantly limits damage.
- Just-In-time and heuristic AV engines block uncharacterised viruses before they have a signature.
