With thousands of new viruses and targeted attacks being created daily, the SECURE Email Gateway provides a number of unique methods to keep your perimeter defences tight.
- The TRUSTmanager IP reputation filter will reject connections from sites that have been distributing viruses and spam.
- Zero-hour anti-malware protection using recurrent pattern detection categorises malware as either confirmed or suspicious so that these messages can be rejected/quarantined for manual inspection.
- Signature based Anti-virus from Kaspersky
- Commonly used file formats such as Microsoft Office, Adobe PDF and OpenOffice feature rich capabilities that are attracting an increasing amount of malware exploits. Clearswift's Active Content Detection inspects for macros, scripts and other such elements that could be used to launch an attack; messages can be quarantined or rejected
- File and Message anomalies are also quarantined by default, as suspicious message encoding, obfuscation, deeply nested files or inconsistent file structures could be used by malware writers to bypass normal detection. A recent example is the Unicode Right-to-Left exploit, even though clever use of Unicode control characters is used to mask the file name, the Clearswift content engine will recognise the file for what it is, typically an Executable.
