A firewall is a device you can set up to monitor and control the flow of information on a network. It keeps hackers and intruders out while allowing legitimate traffic to pass through.
Many small businesses do not have the resources to hire IT staff and manage their firewall systems. Instead, they need something flexible and easy to use. A good router will help secure a network, but it cannot protect against all types of attacks. To find the best firewall for small business, we reviewed dozens of options for different price points and organization sizes. Read on for our recommendations on how to protect your business from cybercrime.
6 Best Firewalls for Small Business

- Cisco ASA is sometimes criticized for being slow and unresponsive.
- A lot of traffic goes through the firewall, which may expose it to attacks from outside the network.
Best for Solopreneurs
McAfee has one of the best software-based firewalls for solo entrepreneurs. It’s not as feature-rich as certain competitors, but it offers reliable protection at an affordable price.
- McAfee products are backed by a strong security engine designed to detect and remove threats that your antivirus can’t. This is why it is considered one of the best firewalls for small businesses.
- The McAfee Premier Business Security software provides complete protection against viruses, spyware, ransomware, and other malware at the click of a button.
- McAfee’s award-winning firewall protects your PC against attacks from hackers, phishing sites, and other malicious websites or emails.
- McAfee’s Total Protection provides comprehensive protection for all your devices — desktop, laptop, and mobile — on both desktop and mobile platforms. It covers up to three devices per subscription (Mac, PC & Android).
- Unlike the paid version, the free version only allows you to scan a single hard drive and lacks many of the more advanced features.
- The free version lacks real-time protection and file repair.
4. Palo Alto
Best for Midsize Organizations
Palo Alto Networks Firewall is best suited for midsize organizations with a mix of high- and low-risk users. The Palo Alto firewall is available in either hardware or virtual form.
- It provides full protection from network attacks by combining packet inspection, application signatures, and VPN connections for remote devices.
- Palo Alto provides network security by blocking incoming and outgoing traffic based on IP address, MAC address, port number, and protocol type (TCP/UDP).
- It supports multiple firewall rules with up to 100 rules per appliance, so you can customize your security package to meet your organization’s specific business requirements and environments (e.g., DMZ or WAN).
- Palo Alto’s primary market is enterprise-level businesses with full-time IT employees. Businesses without a strong IT background may find it difficult to implement and maintain the system.
- It’s difficult to troubleshoot a Palo Alto firewall because there is no common interface for viewing logs, and logs are usually stored in text files that require advanced skills to interpret.

Best for Local Network Protection
Firebox products provide enterprise-level security solutions that also work well with the smaller networks of small and medium-sized organizations. Deep packet inspection prevents intrusion from outside the network. Web blocking functions prevent employees inside the network from opening unauthorized applications.
- Firebox comes pre-configured so you can immediately start to protect your business’s devices from online threats.
- With simultaneous network scanning and real-time blocking of malicious traffic, Firebox protects your entire network in seconds.
- Powerful monitoring tools and quick feedback about your computer’s status mean you’ll always know what’s happening with your network.

- The firewall can respond slowly during heavy traffic periods due to its laggy interface and lack of caching system.
For small networks, consider the WatchGuard Firebox T20 which includes 1 year of standard support.
For medium-sized networks, consider the WatchGuard Firebox M570 which includes 1 year of advanced support alongside the security suite.
Best for Home-Based Businesses
The Norton 360 line of subscription-based products is a good choice to protect your home computer and other networked devices from viruses, spyware, and other malicious software. The two-way firewall protects the system from outside attacks while also preventing a compromised device on the network from sending out unauthorized emails or applications.
- Norton 360 is affordable.
- It has a free trial, so you can test it before purchasing.
- Norton’s firewall solution provides good protection against hackers, viruses, and other threats.
- You can control what websites and programs are allowed to access your computer through the firewall settings.

- The standard limit of protection for five devices may be too small as your business grows.
- The program has a limited number of settings, so it may be difficult to customize the firewall solution for your specific needs.
How to Choose the Best Firewall for Your Small Business
Firewall technology prevents unauthorized access to your network. An effective firewall will protect all the ways that devices connect to your system, and it will block cybercriminals using attack tools like ransomware.
When you buy a firewall, it’s important to compare its features and capabilities to the specific needs of your organization. In evaluating the best firewalls for small businesses, we focused on the following factors:
The cost of a firewall solution depends on its configuration, the size of the network it can protect, and the security services the firewall provides. Even across the same provider, there is a wide range of prices for firewall solutions and threat protection. Small and medium-sized businesses must balance cost with functionality in order to mitigate risk. Determine which security functions are most important for your organization, and then find a solution that meets those needs without breaking the budget.
Number of Available Connections
Large companies may have hundreds or thousands of users on the network at any time. Some users will be at the office working directly with the LAN, and other remote employees will access company servers from outside the network. Small businesses do not need as robust of a network management system as enterprise-level businesses, but they do still need security features like unified threat management and advanced malware protection across the entire network.
Firewall manufacturers will typically indicate the number of users their firewall software can protect. And if you opt for a physical firewall security device, be certain that it has enough ethernet ports to make physical connections with your networked equipment.
Ease of Configuration
Some firewall companies offer out-of-the-box solutions that can protect the network with minimal effort or setup. Automatic setups are great as they can small businesses the cost of bringing in an IT expert. However, generic solutions are not always the right fit for every organization. As you compare firewall options, determine whether your network will require advanced customization.
A Virtual Private Network (VPN) allows you to create a secure connection between two computers over an insecure network such as Wi-Fi or the public internet. If you allow employees at your business to work remotely, they will need a safe way to access your system. Firewalls that include VPN connections will keep your business secure and productive when staff members are out of the office. This feature may be unnecessary for home-based businesses or solopreneurs, but could be crucial for small businesses with flexible working environments.

Firewall Frequently Asked Questions
A firewall is a computer system that monitors and controls network traffic as it passes through the system. Software firewalls are a type of computer program that act as the first line of defense against malicious programs such as viruses, worms, and other network threats.
An intrusion detection system is a software program that identifies attacks on a network by monitoring traffic behavior. If the IDS detects suspicious activity, it can take action to block the traffic or notify the administrator. IDSs use signatures to detect attacks, such as attempts to exploit vulnerabilities in applications or systems or access sensitive data on the network.
Every business owner should have a firewall to protect themselves from attacks that can disable their network or steal sensitive data. Firewalls can be hardware devices or software programs, and they should be configured to block traffic from known malicious IP addresses and websites. The best firewall for small business owners is Cisco Meraki MX given its feature set and approachable pricing.
The cost of a firewall varies dramatically depending on if it is a cloud-based solution or a hardware firewall. A basic software firewall may cost less than $100 per year and cover a dozen devices. Hardware firewalls, on the other hand, cost anywhere from $845 for the Meraki MX to tens of thousands of dollars. The exact price point is determined by network size and exact security needs.
