The way businesses operate has changed dramatically in the last few years. As well as becoming increasingly reliant on technology, the acceptance of flexible working arrangements has seen more employees logging on remotely. While this is a progressive move, it does mean that your business network security faces new threats that need to be addressed to safeguard your assets, finances, and professional reputation.

What is business network security?

A network is a group of computers and other devices that are connected to each other. As it grows in size and complexity, the more vulnerable it becomes, so it’s important to have the right defence framework in place. This involves implementing controls at the edge and centre of your network to prevent unwanted threats from entering, then protecting it from within. While it can be confusing knowing which business network security solutions to consider, a multi-layered approach is the most effective way to keep your systems, apps, and confidential data safe. This can include implementing the following processes:


A firewall monitors the traffic entering and leaving a network, and can come in the form of software, hardware, or both. A firewall in simple form, will filter web traffic based on its source, whereas a more complex option will provide additional levels of control. As well as being installed at the edge of a network, firewalls can be used internally to break it down into subnetworks. This denies hackers access to the whole network if its security is compromised and is under threat. As much as firewalls are effective at supporting business network security, it’s important that the data they produce is interpreted correctly. Any alerts they flag need to be properly understood so that the necessary actions can be taken.

Access control

Business network security begins by limiting access that users have. By regulating who can use or view certain resources, you can minimise the risk of online threats and the damage they cause. Access control can be enforced by asking employees to confirm their identity, so you recognise each user and their device. This can be done by administering a password or login, which will determine what their online privileges are. Depending on their job role, for example, you may decide to restrict their access to certain software to prevent breaches of data. Whatever cyber security policies you enforce, it’s important to recognise that most cyber attacks are successful because of human error, so prioritise training your employees to recognise suspicious looking emails and report unusual activity.

Antivirus and anti-malware software

Malware (malicious software) is a type of software such as a virus or Trojan that is infiltrated into your device. It is the force behind most cyber attacks and causes damage by hacking into networks and destroying and stealing data. Installing the right anti-malware software will support your business network security by scanning for harmful threats, checking for anomalies, and removing any identified malware to minimise potential damage. To make the most of the protection that antivirus and anti-malware provide, a strong frontline defence must be deployed. This can be achieved by regularly updating your software, so it continually monitors threats and recognises the techniques used by hackers.

Virtual private network (VPN)

A VPN is a security tool that enables employees to access their business network safely when they’re outside the office. It does this by masking their identity and location, regardless of whether they’re using a public Wi-Fi connection 1,000 miles away or logging on at home. By creating an encrypted connection, third parties are prevented from tracking online activities or accessing sensitive information such as downloaded files or customer data. Because smartphones and tablets also benefit from the safety controls of VPNs, they are commonly relied on to provide an enhanced layer of privacy. Ultimately, advances in technology have made the world a smaller place, and your business network security protocols need to reflect this shift in the working landscape, and the vulnerabilities that come with it.
