Methodology For Choosing The Best Network Security Software

With so many options to consider, there are certain factors you need to evaluate when comparing network security software services. Use the following factors as a buying guide to help narrow your choices as you’re shopping around.

Malware, Privacy, and Phishing Protection

Malware protection is a crucial component of any network security solution. The software should also be able to fight adware, spyware, and phishing. 

These are fairly basic security standards. But they are the foundation of a good network security system. You’ll need to have them regardless, so it makes sense to get everything from the same provider.


Firewalls are essential for network protection. As the name implies, this feature acts as a barrier between your trusted network and external networks. Generally speaking, a firewall can monitor all of the traffic on a network and prevent harmful access. 

The best firewalls monitor all of the applications running on your network and restrict inappropriate use. They usually keep a closer eye on new or unknown programs running on the network. This helps neutralize any stop suspicious behavior before it becomes a problem. 

Virtual Private Networks (VPNs)

VPNs extend network security to internet connections. It secures your traffic and can even hide details like your IP address and location. 

Not every network security software comes with a VPN out of the box. You may need to get this as an add-on or upgrade to an all-in-one security suite. 

Network Access Control

This feature prevents intruders and attackers from infiltrating your network. You can set up access control policies and rules for users and devices. 

For example, you could give employees full access to your network from work-issued devices but deny network access to their personal devices. This is an important factor to consider for devices in the workplace.
