Cisco Ironport Email Security Appliances

Sophos is an industry leader in anti-virus filtering, offering consolidated protection against multiple malware threats such as viruses, worms and Trojans. With the highest performance virus scanning technology in the industry and unique denial of service prevention, Sophos anti-virus technology provides a fully integrated layer of virus protection on the IronPort C-Series™ email security appliances.

The IronPort C-Series with Sophos Anti-Virus provides two layers of defense against potential viruses.

Features

Multiple Detection Methods: Protection Against the Widest Variety of Virus Threats

During the scanning process, the Sophos AV engine analyses each message and file, identifies the type and then applies the relevant technique to ensure highest throughput and efficacy. The Sophos AV engine employs multiple detection methods such as:

Sophos' Dynamic Code Analysis™ technology utilizes sophisticated pattern matching techniques and identifies viruses by rapidly analyzing specific code sequences known to be present within a virus. Virus patterns are created to ensure that the engine catches not only the original virus but derivatives within the same virus family.
Advanced emulation technology along with an online decompressor for scanning multi-layer attachments is utilized to detect polymorphic viruses. The robust engine supports multiple scanning modes to optimize performance.
Heuristic techniques are utilized by the engine to ensure that variants of viruses are caught with minimal information available about virus code patterns.

Ease of Management and Usability

Administrators have multiple options to handle virus infected messages thereby allowing customers to tailor their anti-virus policies to suit their network requirements. The IronPort solution detects potentially dangerous messages, giving the administrator full control over how these messages are handled by the system.
Automatic signature updates ensure that your network is protected at all times. IronPort email security appliances automatically download the latest versions of virus signatures at regular intervals and scan incoming and outgoing mail with these updated signatures immediately.

The Only Signature-based Gateway Anti-Virus Technology Integrated With a Preventive Solution

Virus Outbreak Prevention and Protection – During any virus outbreak, there is invariably a period of time between virus detection and when the actual anti-virus identity file is deployed. During this period, administrators can utilize IronPort's Virus Outbreak Filters technology to identify and quarantine viruses based on known patterns and delete or archive the messages until new identity files can be updated. This innovative preventive anti-virus solution is fully integrated with the Sophos AV engine and has the ability to rescan messages automatically when there are new virus signature updates available during an outbreak.
