8 Key Points to Consider When Purchasing a New Firewall

Firewalls have progressed far beyond the days of two-way network permissions based on their port. However, another important concern arises with these developments: how do you understand that you are choosing a firewall that protects your small business from true cyber security risks and you even know what these dangers are?

In this tutorial, we will explore how firewalls provide the basis for the internal network security of your firm and the advice you need to choose which firewall is the best for your application with good network firewall prices.

What is a firewall for the network?

A firewall works as the key safety barrier for incoming and outgoing traffic on your network in its simplest definition. In order to defend your network from security threats, firewalls are designed to execute various key IT security activities. You do that by reading traffic information from or into your network and assessing, in accordance with preprogrammed definitions, if it is safe.

Why is it critical to have a firewall in your organization?

A firewall is a network security device that continuously monitors incoming and outgoing traffic, deciding whether specific traffic on the basis of a set of security rules is permitted or blocked. A firewall constitutes the first line of perimeter defense for your computer network by creating a protective barrier between safe and controlled internal networks that are trusted and not trusted by external networks like the Internet. Hardware, software, or a combination of both can be a firewall. A good Sangfor next-generation firewall offers a high level of protection and a variety of possibilities with low network firewall prices.

Your applications are visible and controlled:

Traditional port-based firewalls only give your apps and end-users accessing your network little control and visibility. You obviously don’t want everyone to use programs like YouTube or Facebook, but what about your marketing team or teachers who stream a video for a particular lesson? With the correct firewall in place, you can apply policies to select end-users that give access to individuals who have occupations that are relevant to the apps.

What about end-users like guests, or what about your patients when your organization is a hospital? Various end-users can apply different policies to prevent them from accessing particular applications.

Sangfor Next-gen firewalls may also restrict access to some elements of programs. For instance, a user could utilize Facebook calling and texting but can’t put it on his timeline or on a “wall” friend.

High availability built-in:

This is the typical backup option you need if you can’t risk losing your firewall at all. Basically, if your primary firewall stops for any reason, it will cut into a secondary firewall to restart its functionality.

This functionality is not too crucial if you are a tiny organization that can run for a short time without a firewall while it is restored. However, if you are a large service provider with hundreds or thousands of client data, you will require integrated high availability to avoid harmful exposure if your primary firewall stops operating.

Virtual private network:

A virtual private network is a remote access form that enables users to connect to a secure network outside the company. To support remote access, a special sort of firewall is required. Some firewalls include unique VPN software to connect to on-client PC while others have a more generic VPN standard. The number of remote users influences the sort of firewall you need and the cost. In general, you can utilize a more advanced sort of remote access technology instead of a VPN. VPNs are usually used for connecting the site to the site. Security problems might arise for VPNs depending on how they are configured and used.

Data consolidation:

Security-in-depth is a methodology that protects an asset through numerous procedures and devices to limit the chance of compromise. For instance, the SANS Institute suggests that a firewall be complemented by intrusion detection, DPI, and an anti-virus/anti-spam/anti-malware solution. Each aspect of this design individually manages various threat vectors. While firewalls may identify a port scanning assault, a SQL injection operation that can be identified using DPI cannot be noticed.

Technical assistance:

Hardware does not work. Worse still, it doesn’t indicate that a product that is new and fresh from the factory will work well. Check for available technical support 24×7 and complete technical support agreements with the maker of the firewall.

Call the Sangfor technical support team before purchase and ask questions about configuration and deployment. The speed and correctness of the answers you obtain will disclose the service that you receive when the unit malfunctions.

Risk assessment:

Ideally, threat intelligence and risk assessments will inform your decision. You will know which assaults are most common and how adversely your organization could be affected. All of your defenses, including firewalls, should be tailored to defend you best against such serious hazards.

The risk evaluation will also depend on the sensitivity of your firewall-protected data. In order to prevent data infringement or service disruptions, organizations in highly regulated or important areas such as finance or healthcare could need stronger protection.

The total cost of ownership calculation:

Total network firewall ownership costs, whether physical, virtual, or cloud-supplied, comprise the following considerations:

  • Procurement expenses
  • Deployment costs
  • Management costs.
  • Seller or an authorized partner provides annual support and/or services
  • Installation, integration, and continuous maintenance.

If there is one area where many firms underestimate TCO, the management is involved. There is a dearth of experienced and trained security workers in the sector, and all organizations must measure the advantages of manual and humane management against automation savings and flexibility. In any case, companies should take into account the time and resources needed to implement and maintain network firewalls efficiently. A miscalculation of this component can dramatically affect total TCO.
