The firewall (FW) is probably the most important element of a BDS (breach detection system) network security infrastructure that is used to identify malware activity inside a network once a breach has occurred. And, as technology is changing rapidly and more malicious cyber threats are compromising networks, the robust security infrastructure of every business should include a next-generation firewall (NGFW).

What’s the difference between FWs and NGFWs and why does your business need one? Read on and find out everything you need to know. The number one tech company operating under the ethos of delivering business outcomes and speed to value on IT investment for businesses across Australia – 6YS – has compiled the following detailed guide:

How do FWs Differ from NGFWs?

A next-generation firewall is actually part of the third firewall tech generation. It is a mix of a traditional firewall and other network device filtering options, including intrusion prevention, deep packet inspection, TLS/SSL decryption, website filtering, antivirus inspection, bandwidth management, etc. In other words, it is an advanced version of the traditional firewall.

First and foremost, when speaking of similarities, they both use VPN support and dynamic/ static packet filtering to make sure that all the connections between the firewall, network, and internet are secure. However, they differ in several other ways.

The biggest difference is that next-generation firewalls have deep-filter packets and large-scale control and visibility over applications. Furthermore, NGFWs use signature-based IPs and whitelists to discriminate between secure and unwanted apps. Finally, they also protect against various threats like spyware, malware, malicious URLs, vulnerability exploits, and other APTs (advanced persistent threats).

Why Does Your Business Need an NGFW?

It goes without saying that every employee is using and accessing a number of applications on different devices to complete their work tasks, which has a great impact on security. But, that’s not all! Network security is also affected by data centre expansion, virtualization, cloud-based solutions, and mobility.

In case of a threat, the traditional FW would either try to block all application traffic that impedes business operations or allow full function, putting security at risk. By contrast, NGFWs balance between these two extremes and safely enable apps by considering application identity, type of content, and who is accessing. Thus, we can agree that a next-generation firewall is exactly what your business needs to boost its security.

What are the benefits of NGFW?

There are numerous benefits to enjoy if an NGFW is implemented in your business:

  1. Cyber threat prevention – protects against security breaches and keeps business operations safe.
  2. Automation – works together with other security infrastructure
  3. Comprehensive network visibility – provides contextual awareness and a detailed view of activity.
  4. Versatile management options – fits business distinctive requirements.
  5. Rapid detection – identifies threats in seconds and prioritises alerts.
