IT systems security has become a very critical area for most organizations. What with cybersecurity threats, malware attacks and escalated virus attacks. Thus, the IT staff would definitely want to upgrade company network security systems. However, it can be a challenge purchasing the right network firewall with the capability to meet organizational IT security challenges. This network firewall buying guide will assist the IT staff in acquiring the best network security solution.

Be that as it may, most organizations would like to invest in a computer security system that offers visibility into web and application activity as a priority number one. The ability to identify the affected computers, programs or processes is at the center of timely incident response. Following accurate identification and isolation, cleaning should be fast-tracked to avoid prolonged system downtime.

Next, the system should be able to protect the network from threats; not only known but also unknown threats. No organization would risk the loss of data due to a cyber-security attack. Network visibility should help stop infections from spreading, and quicken recovery. Lastly, the solution should offer automated threat detection, isolation, and removal. The firewall depends on different technologies such as exploit detection and deep learning to catch elusive malware. The goal for integrated protection should about achieving maximum benefit from server security, endpoint protection, and the firewall.

Requirements when buying the network firewall

The Intrusion prevention system

Hackers keep upgrading their skills to escape detection during an attack. Therefore, the intrusion prevention technology built into the firewall system should be complex enough to detect attempted breaches. Detecting modern-day malware attacks will require a more sophisticated approach. Because signature-based detecting just cannot cut it. Thus, as this network firewall buying guide recommends a firewall that relies on behavioral analysis technology together with deep learning.

Web security technology

Adequate protection requires the firewall system can detect unwanted apps, bots, and malicious traffic. Above all, web security can only be assured when a system exists to scan DNS addresses and dynamic IPs. Specifically, Web and application firewall technology will be very important for those organizations hosting private servers in-house. The system comes with reverse proxy to harden the server from being attacked.

The best web security firewall should offer protection against common threats like Cryptojacking. As a matter of fact, most firewalls have inbuilt antivirus engines that continuously emulate JavaScript code on browsers. Still, there should be an efficient synchronization between the firewall and the hosts within a network. Efficient synchronization should reveal the health statuses for every endpoint on the network so that timely action can be taken in case one is compromised.

Email security

Most social engineering attacks can be propagated through email. Attackers will likely exploit emails to gain unauthorized entry into a network. Therefore, a good firewall should have a good anti-spam system to protect against network spamming. Also, the firewall should have good anti-phishing technology to protect against password theft and loss of private information. The firewall should automatically subject all incoming emails to thorough scanning including all email attachments.

Additional features in the Network firewall buying guide

The capability for multi-site connectivity

Most organizations would like to have multiple secure connections to different locations. Furthermore, VPNs provide secure tunnels for sharing IT infrastructure resources with branch and remote offices. The network firewall should be able to offer a simple yet reliable remote site VPN connection solution. As a matter of fact, most firewalls with advanced features have the software-defined wide area networking for delivering remote site connectivity.

Firewall installation and deployment

With a similarity to the IP PABX telephone systems, network security firewalls come with different deployment options. To begin with, the firewall system can be purchased as a physical appliance. As a physical appliance, it has to be mounted in a network cabinet inside the server room. Mostly, companies would have in place a physical server room access control.

Secondly, the firewall solution can be implemented as a cloud solution. In this case, there will be no purchase of a physical appliance. All the tools required for network security will still be available as in the hardware form. However, the IT security staff will be able to login to the firewall through the online cloud account.

The firewall performance

Performance remains a key factor when planning to purchase a firewall. The ease with which users can execute various official company tasks will depend on how fast the firewall delivers various services. In particular, cloud services entirely depend on firewall performance. Hence, the IT staff should consider firewall throughput that can not only support the current users but has an allowance to accommodate more people in the future. Additionally, load balancing will also boost WAN performance.

Essential firewall services

Automated response and alert

Network visibility is a feature whose value cannot be underrated. In addition to the rich reporting dashboard, application visibility offer remains an important tool for gathering actionable intelligence. In fact, the firewall should detect and isolate and clean any threats without needing human intervention. And, the logs stored detailing all the action executed; with an option for rollback. At the bare minimum, these features must be present on any firewall.

Integrated protection framework

In as much as firewall offer protection at the gateway level, it should not be able to integrate with endpoint security. Such integration will bring about greater coordinated network protection leading to better identification and isolation of threat. With the improved synchronization between the firewall system and the endpoint protection software, it will be easy to control apps and web activity.

Simpler user interface

Sometimes, firewall installation and configurations can be a very frustrating experience. The very first generation of network firewalls proved to be complex to install. Moreover, firewall installation required an elaborate training session from the vendors. With such complexities, clients could not enjoy all the features built into the firewall system.

However, the firewall solutions of today have easy to understand interface. Most network protection features can easily be enabled and disabled as need be. The simple user interface has enabled user clients to enjoy the full potential of the firewall. Simplicity in configurations, installations, and deployment remain a key factor in network firewall buying guide.

The above network firewall buying guide illustrates the key features that must be available in a good firewall for adequate protection. Contact us today for the best network firewall security solution for small, medium and large enterprises in Kenya.
