Security and Multi-Layer Antivirus

No computer network can be 100% protected from threats that the internet and attackers can bring. But with a smart IT security policy and using a layered approach, you can reduce your company's risk to attack.

Viruses today are more blended and have a higher payload than ever before. This means that they are easier to distribute and can do greater damage. Viruses today can attack networks at even the lowest level which means they can bypass desktop and server antivirus software. Software antivirus no longer provides the complete protection that it once did.

So what is layered antivirus and network security and how should you approach it? Simply put, it is like placing a defense barricade at every possible entry point onto your network. A typical layered antivirus solution will include server AV, desktop AV, gateway AV, email AV, and some type of intrusion detection/prevention service (IDS, IPS).


This approach will not only protect from threats that come in at the computer and file system level, but will also protect your network from denial of service and other network level attacks.

A layered approach also helps provide efficiency and load-balancing on your network.
