Why do we need next-generation firewalls?

The work of global networking and security teams has traditionally relied heavily on firewall technology. Traditional firewalls analyze data at the network layer, including IP addresses, ports, and protocols. Since the firewall is unaware of the "status" of the connection, this requires the creation of separate rule sets for incoming and outgoing traffic. Because the "status" of a connection may be monitored by the second-generation (circuit) firewall, engineers need only establish a single set of rules that applies to all bidirectional connections.

The intelligence of the third generation of firewall technology allows it to learn how different protocols function and adapt to their use in real-time. This update marks the debut of the NGFW capability currently in use.

To put it briefly, NGFW (Next-Generation Firewall) can be thought of as adding intelligent firewalls to the border of classic firewalls networking in addition to application layer detection, intrusion prevention system, and other protective layers. Commonplace security for ports and protocols. We'll go through the main advantages of NGFW over conventional firewalls in this article.

Advantages of a Modern Firewall

Security functions such as IDS and IPS

For threat detection and packet blocking, the NGFW works in tandem with Intrusion Detection and Prevention Systems (IDS/IPS). Using these tools, you can fine-tune your packet content filtering strategies. Using user behavior as a baseline, these features can detect and respond to anomalies in activity sets, threat signatures, and smart attacks.

Use of Only One Control Panel Access

In contrast to older firewall technologies, which require manual setup and configuration for each individual firewall, next-generation firewalls are accessible from a central console.

Several Layers of Defence

In a data architecture environment with complex and changing requirements, traditional firewalls' ability to block access through ports (a single layer of protection) may prove ineffective. By inspecting traffic from Layer 2 through Layer 7 and comprehending the precise nature of the data transmission, NGFW offers multiple levels of security. The firewall will only allow the transfer of data if it conforms to the policy, it has been given.

Infrastructure Simplified

There must be a new security device for every new threat. Newer generation firewalls, however, make it simple to manage and update all security protocols from a central location. The complex security infrastructure is simplified, and operational time is saved.

Make the most of your bandwidth capacity

With conventional firewalls, as the number of security protocols and devices grows, network performance suffers. This occurs because the addition of security hardware and software is causing private network speeds to fall short of expectations. Next-generation firewalls, however, make it possible to reliably reach maximum throughput, regardless of the number of connected devices or the type of security protocols in use.

Protection from Viruses, Ransomware, Spam, and other forms of Endpoint Security

To keep sensitive company information safe, NGFW includes anti-virus, anti-ransomware, anti-spam, and endpoint security tools. These features make it unnecessary to use other programs for these tasks. Incorporating NGFW into your security setup will not only save you time and energy but will also make it much simpler to keep an eye on and rein in cyber threats.

Capabilities of Roles Access

Modern firewalls can automatically identify users thanks to this feature. Additionally, it can be set up with multiple user roles to control who has access. With the aid of this function, businesses can control who can see what data and content. Similarly, businesses can choose to share only certain pieces of information with the public while keeping others under wraps.

Conclusion

Overall, NGFW is quite effective. They introduce more sophisticated security methods and the proper topology at the network's edge or within the local area Networking lan, compared to older generations of firewalls. The technological debt incurred from implementing many, disparate security systems can be efficiently aggregated in a single platform using the features of next-generation firewalls (NGFWs), which can then be used to strengthen security, simplify management, and cut costs. Profitability is very high (ROI).
