Researched by: [Capterra](https://www.capterra.com/resources/author/capterra/) Updated on April 1, 2026 Firewall software is a cybersecurity tool that monitors, controls, and filters incoming and outgoing network traffic based on a predetermined set of security rules. It prevents unauthorized access by malware, hackers, and other virtual intrusions that may attempt to infect business systems or networks.  Firewall software solutions are installed on computer systems or servers to provide and maintain network security. They can be installed remotely and generally require a small amount of device storage space, enabling even small businesses to protect multiple company devices at a low initial cost. * * * For more information consult our [Firewall Buyers Guide](#buyers-guide-content) Page 1 of 3 ## Top-rated software of 2026 ### Fill out the form and we'll send a list of the top-rated software based on real user reviews directly to your inbox.

Firewall software can be configured to help your business meet government and industry regulations to avoid legal penalties.  - **Creates a first line of defense against hackers:** Without firewall software, unauthorized third-party users may attempt to hack your company's sensitive information. Firewalls help prevent such intrusions by providing a reliable shield between your business network and the internet. - **Monitors network traffic:** Any data that flows in or out of your business network is susceptible to malicious threats that could compromise your company's data. Firewall software monitors the data flow based on pre-established rules or filters to ensure your business network stays secure.  - **Filters content:** Firewall software can help your business control the type of content employees have access to. The software filters out websites that host malware or contain inappropriate content for the workplace, thereby improving employee security. - **Sends malicious activity alerts:** Firewall software solutions track IPs and signatures to identify users or applications that may threaten your network’s security. When a malicious agent is detected on a computer system, the firewall software notifies you immediately. * * * ## Typical features of firewall software - **IP filtering:** Control or restrict network traffic based on the source and destination of IP addresses, protocols, and ports to block malicious traffic. - **Network monitoring:** Track and collect data on the current health of servers and other network components. - **Reporting/analytics:** Track key metrics such as CPU and memory utilization, number of intrusions detected, and network traffic flow to gain insights into your company's network security.  - **Access management:** Control and manage user authentication and access to company data or resources. - **Alerts/notifications:** Receive alerts and notifications when malicious software is identified within your company's network. - **Content filtering:** Control or restrict access to certain web content or applications to prevent malware from entering your company's network. - **Intrusion detection system:** Receive alerts when security is breached by third parties.  - **Intrusion prevention system:** Monitor network traffic to prevent malicious activities or intruders. - **Log access:** Collect, search, and analyze historical access, audit, and security logs. * * * ## The cost of firewall software Most products in this market are priced as annual subscriptions. Pricing can be divided into three pricing tiers based on the starting prices:  **Price ranges\*:** - $19 - $48 - $48 - $99 - $99+ _\*The pricing included is for the entry-level/lowest-priced offering found on vendor websites on April 12, 2022. These ranges correspond to the 25th, 75th, and 100th percentiles of pricing information gathered from vendor websites of sample products._ * * * ## Considerations when purchasing firewall software - **Compatibility with broader security platforms:** No matter which firewall software solution you choose, it is crucial to check its compatibility with your existing enterprise security stack. You should be able to plug the firewall software into your current security platforms so it can access, analyze, and inform policies on all network activity. - **Number of users:** When purchasing firewall software, be sure to consider the number of users that will need access to the software. If you’re a small business that intends to grow substantially over the next few years, opt for a firewall tool that can not only protect your business networks from malicious users but also accommodate additional user seats as your business grows. - **Installation and troubleshooting support:** Once you have chosen a firewall platform, ensure that it is properly installed. Errors during the firewall setup process can lead to security lags that could be exploited by intruders. Select a vendor that offers guidance on the best approach to set up a firewall as well as provides customer support further down the road. - **Need for a virtual private network (VPN):** A VPN enables users to securely connect to a business network from out-of-office locations. If your company has a large number of remote workers, consider purchasing a firewall program that features a VPN to ensure your network stays secure when establishing remote connections. * * * **Sources** Products evaluated for the pricing calculation were taken from Capterra's [firewall software directory](https://www.capterra.com/firewall-software/), sorted by number of reviews.
