Network security is the backbone of a healthy IT infrastructure. Every element of your network relies on the transfer of information, which is one of the reasons networks can be vulnerable to malicious attacks. By placing security elements at all critical network checkpoints, you can give the right people access to the resources they need while helping to keep corporate data and IT systems safer.

At the basic level, organisations lack antivirus software on desktops, do not have a centralised firewall, and do not have an internal server for basic network services. As organisations progress through the optimisation model, they begin adding features to make their systems more secure and more efficient.
Some of the challenges IT professionals face in their mission to provide more secure and reliable services include:
 - Preventing the introduction of viruses and malicious content.
If allowed onto the corporate network, computer viruses can cause havoc on computing systems, disrupting operations, infecting data, and even enabling theft of valuable company assets. Regardless of how computer viruses sneak onto the network, the result is often devastating and expensive.
- The increasing use of mobile and wireless devices.
This adds new complexities, costs and potential vulnerabilities in ensuring secure access for mobile users.
- Keeping the network running, available, and accessible.
As a core IT service, the network must be available and accessible. With so many different systems and devices on the network today, access control can be complicated and inconsistent. Solid security tools that offer centralised control can simplify this complexity and increase security without compromising access.
- Balancing access and security.
Distinguishing between threats to your network and legitimate access requests is a key challenge. The most secure system in the world is the one no one can access, but it is also practically useless. Therefore, security threats must be recognized and neutralized without a disruption in service.
