Legacy protection is no longer enough – here’s why

Traditional security and protection tools are no longer adequate to ensure protection – yet many organisations continue to rely outdated systems for security. Find out the biggest vulnerabilities you could face by running legacy protection and how you can protect against them.

Most legacy systems and applications were developed when cyber security was not as greater risk as it is today, and many no longer receive updates from their developers. Despite this, businesses continue to operate traditional tools as their main source of defence from cyber threats.

In today’s digital world, operating up-to-date security solutions is paramount to protecting your business assets and data. We’ve shared the most common tools and how your business can heighten protection.



Ironically, passwords have become one of the weakest links to modern day cyber security. This is usually because users create simple passwords and recycle them across multiple accounts, leaving the door wide open to hackers.

A basic password policy isn’t enough to ensure protection of accounts, devices and networks. Implementing a password management tool and multi-factor authentication is a simple and effective means to tighten security and make it one step harder for hackers to access accounts.



Antivirus software is designed to recognise, flag and remove malware (such as a malicious file) that have entered a network.

The problem is, with over 350,000 new version of malware created every day,* it’s impossible for developers to write antivirus software fast enough to be able to detect and protect against new threats.

Organisations must look to cloud-based antivirus, a modern solution that uses machine learning to detect and isolate malware in the network. Cloud-based antivirus software automatically pushes the latest updates across all devices on the network as soon as a threat is discovered, ensuring all business devices are always up-to-date.



The trusted first line of defence for over 25 years, legacy firewalls were created to protect unauthorised access to networks and systems, by acting as a barrier for incoming traffic. However, traditional firewalls have limited scope and cannot keep up with the high flow of traffic that enters and leaves a network in modern day business.

Next Generation Firewalls (NGFW) should now be deployed to prevent more advanced attacks in today’s landscape. NGFW build on the traditional firewall framework, with additional functionalities such as improved detection of suspicious activity, automated and more efficient response times, and contextual awareness of which assets are most vulnerable.
NGFW is quickly becoming standard for most organisations and is something you should seriously consider for your business if not already in place.


If it ain’t broke, why fix it?

Whilst many legacy tools might continue to work on your network or devices, the risk of doing so is becoming too much of a concern to ignore.

Cyber crime is predicted to cost organisations £6 trillion worldwide by 2021** and migrating away from legacy security tools is the first step to limiting vulnerabilities and reducing risk of an attack on your business.

As organisations continue to undergo the all-important digital transformation, upgrading legacy protection must be taken into account and built into your ongoing strategy. Businesses need to balance the cost of new software against the detrimental impact of an attack – with consequences of a compromise including business downtime, loss of profit, and destruction of reputation.

This is not to say that passwords, antivirus and firewalls shouldn’t be including in your cyber security strategy; they should. A layered approach is the best way to ensure you’re protecting your network and users in the best way you can.


Don’t leave your business unprotected by outdated technology

Prevention is always better than cure and is much more cost effective in the long run.
