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

But, what’s the difference between FWs and NGFWs? Why does your business need one? Read on to find out everything you need to know about them. 6ys - a company delivering business outcomes and speed to value on IT investment for businesses across Australia - has comprised the following detailed guide for you:

How Do FWs Differ from NGFWs?

A next-generation firewall is actually a part of the third firewall tech generation and 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, and more. 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 in order to make sure that all of the connections between the firewall, network, and internet are secure. However, they do differ in many other ways.

The biggest difference between them is that next-generation firewalls can deep-filter packets and have large-scale control and visibility over applications. Furthermore, NGFWs can use signature-based IPs and whitelists to discriminate between secure and unwanted apps. Finally, they can 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 tasks which have 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, traditional FW would just either try to block all application traffic that impedes business operations or allow full function which puts security at risk. Therefore, since NGFWs balance between these two extremes and safely enable apps by considering application identity, type of content, and who is accessing, we can agree that a next-generation firewall is exactly what your business needs to boost security.

What are the NGFW Benefits?

There are numerous benefits your business can experience if an NGFW gets implemented including the following:

  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’s distinctive requirements.
  5. Rapid detection – identifies threats in seconds and prioritizes alerts.
