Be sure to check out the various features before purchasing a firewall system. Firewall tools should have most or all of these features:

Features Of Firewall Software

1. Access Control and Rules Configuration 

Firewall tools are gatekeepers controlling user access between networks and the Internet. A firewall software system can enable you to set permissions and authentication rules that only allow specific users to enter a network. It also controls access to servers or websites unless authorized authorization is given, ensuring stringent and comprehensive security.

2. Customized Restrictions

Antivirus software allows network administrators to specify the websites and servers users can access freely. Administrators can customize the settings to block non-business-related webpages and block IP addresses or servers of any potential threats to data security.

3. Intrusion Detection and Prevention

Firewall system needs to give instant alerts in case of any virtual or physical intrusions. Most firewall systems alert the network administrator in case of any security breach. This helps the administrators identify potential hackers or malware and take preventive measures to prevent network breaches.

4. Task Automation

One of the best functionalities of firewall software tools is automating mundane tasks to save time and increase efficiency.

Invest in the best firewall tools with in-depth reporting features to learn about vulnerable touchpoints and unapproved access attempts.

Things To Consider While Purchasing Firewall Software For Your Organization

Here are some crucial aspects to keep in mind while purchasing enterprise firewall solutions are for your organization:

How To Select Firewall Software

1. Visibility and Control of Applications

Traditional port-based firewall systems provide a limited view of applications and users accessing your private networks.

If you opt for cloud-based firewall software, you can customize policies to allow access to specific applications. Hence, different end-users can have different restrictions that may prohibit them from accessing certain applications. Remember to invest in firewall system that gives you complete visibility and maximum control of applications for streamlined workflows.

2. Device Support

One of the key requirements to consider before investing in a firewall system is device awareness and support. You need to be aware of the number and kind of devices your employees use to access computer networks in your organization.

Device support and awareness enable firewall software to identify, report, and track various devices on your network. It allows administrators to enforce different device policies and ensures stringent security protocols.

3. Size of Firm

It is important to consider your organization’s size and type of industrial domain while purchasing firewall system. If your firm is large, you must ensure that your firewall system can accommodate a high user base. It is also critical to factor in future growth since most firewall systems are not scalable at a later stage.

Ensure your firewall tools are state-of-the-art and do not lack sophisticated features. Discuss system functionality with your service provider and ensure that your firewall solution contains important features such as malware detection, spam filtering, and website blocking.

4. Budget

Your budget will be the deciding factor in getting the best firewall system. Modern firewall tools are more affordable than you think, so scan the market well to be aware of the prevailing price range.

Most service providers are happy to help you invest in firewall software that fits your budget. They may customize the pricing and payment options to suit your business requirements. Lastly, remember not to cut corners, as you do not want your firewall solutions to perform poorly, so consider it a long-term investment that will reap multiple benefits.

Challenges Faced While Implementing Firewall

While adopting a firewall system is one of the best decisions you can make for your organization, you must ensure that it will not backfire. Here are some potential issues that may prove to be challenging while implementing firewall solutions:

Challenges While Implementing Firewall Software

1. Range of Devices

With new trends such as BYOD (bring your own device to work), employees use mobile devices, laptops, personal computers, and tablets. It is often challenging for firewall software to support such an exhaustive range of devices. Hence, it is essential while choosing firewall software to ensure that it covers all possible devices so your organization can continue with practices such as bring-your-own-device.

2. Over Strict Restrictions

Enterprise firewall solutions allow administrators to customize their settings to make them as strict or relaxed as required. However, it is important not to tighten restrictions so much that they may hamper business operations. Administrators may inadvertently restrict entry to some web domains or servers, leading to delays and inhibiting employee productivity. Hence, firewall solutions must be implemented wisely for maximum benefit and to create a supportive work environment.

3. Obsolete Security Measures

Some features of firewall systems, such as port-based rules, are outdated in the current digital age. Most applications and traffic have now switched to SSL or default to an open connection port. Hence hence the old rules are rendered obsolete. While implementing firewall, choosing a system with top-of-the-line latest features is vital for better functionality and operational efficiency.
