How we chose the best firewalls for small businesses

Small businesses need firewalls that are simple to use, secure, and able to grow with them. We focused on options that offer strong protection without requiring a dedicated IT team.

Each firewall was chosen based on key factors:

• Ease of use: A good firewall should be easy to set up and manage for non-technical teams.
• Strong protection: The firewall must block threats like malware, phishing attempts, and unauthorized access.
• Scalability: As your business expands, the firewall should handle increased network demands.
• Affordability: The cost should fit within small business budgets while providing reliable features.
• Advanced tools: Features like VPN support, cloud integration, and AI-based threat detection were major strengths.

We aimed to find firewalls that strike the right balance between security, usability, and cost. These choices give small businesses the tools they need to stay safe without unnecessary complexity.

Honorable mentions

While the firewalls in this additional list below offer strong features and solid performance, they didn’t fully meet the key considerations for small businesses outlined in this guide. Here’s a closer look at these honorable mentions and why they didn’t make the final list:

Ubiquiti EdgeRouter

The Ubiquiti EdgeRouter is a powerhouse for anyone who loves tweaking network settings and diving into advanced configurations. IT pros swear by it for its top-notch performance and ability to handle complex setups with ease. If you’re running a tricky network and know what you’re doing, this router is a dream.

All that power comes with a steep learning curve. The EdgeRouter isn’t designed for small businesses without IT experts on hand. Setting it up and managing it can feel like solving a puzzle without a picture, and that’s not great if you’re just trying to keep things simple. For teams who need plug-and-play tools, this one’s more work than it’s worth.

Netgate pfSense Plus

Netgate pfSense Plus is like a Swiss Army knife for network security. It’s packed with robust features, highly customizable, and backed by an active community of tech enthusiasts. If you know your way around a firewall and love having control over every detail, this open-source option offers serious value.

The offered flexibility comes at a price—time and expertise. Setting up and managing pfSense Plus takes significant technical know-how, which most small businesses don’t have. While it’s cost-effective, the DIY nature and inconsistent support can make it a challenge for teams without IT help. For most small businesses, simpler options are a better fit.

Cloudflare SSE & SASE Platform

The Cloudflare SSE & SASE Platform is amazing for cloud security. It combines firewall functionality with zero-trust network access, making it a great choice for businesses navigating the challenges of cloud-based environments. It’s scalable, flexible, and packed with tools to protect data and manage access securely.

While it’s impressive, this platform is built with larger enterprises in mind. For small businesses, it can feel like bringing a tank to a bike race—powerful, but more than what’s needed. Its advanced features might be overkill for simpler setups, and managing it can be a bit much for teams without dedicated IT support. If your business is small and scrappy, there are more straightforward options out there.

NordLayer

NordLayer is all about keeping things simple and affordable without skimping on security. It’s known for strong encryption and built-in malware protection, making it a solid choice for businesses that want dependable cybersecurity without a lot of hassle. The user-friendly interface and budget-friendly approach make it appealing for teams who prefer straightforward tools over complex setups.

While NordLayer is great for basic needs, it doesn’t offer the advanced firewall-specific features some businesses require. It’s more of an all-purpose security tool than a dedicated firewall, which might not cut it for small businesses with growing or more complex networks. If simplicity is all you need, it’s worth a look—but for full-scale firewall capabilities, other options are a better fit.

Check Point Next Generation Firewalls (NGFWs)

Check Point NGFWs deliver advanced security features designed to tackle modern cyber threats head-on. They offer tools like intrusion prevention, application control, URL filtering, and real-time threat intelligence. These firewalls provide businesses with strong, multi-layered protection to secure their networks, applications, and data.

While packed with features, Check Point NGFWs are geared more toward enterprises than small businesses. Their complexity and higher price point make them less practical for smaller teams with limited IT resources. For small businesses, they might feel like over-preparing for a threat that simpler, more affordable firewalls can already handle.

Comodo

Comodo is a budget-friendly choice for businesses that need basic firewall protection without a lot of extras. It’s designed to offer affordable, easy-to-use security, making it accessible for companies that want simple tools to get the job done. If you’re looking to cover the basics without overspending, Comodo is a practical option.

While Comodo does the job for minimal security needs, it doesn’t go beyond the basics. For small businesses with more complex networks or a need for advanced features like AI-driven threat detection or cloud integration, it might fall short. It’s a decent choice for startups or microbusinesses, but growing companies may need something with a bit more firepower.

OPNsense (Full Version)

OPNsense is a solid open-source option packed with features like intrusion detection and VPN support. It’s highly customizable and gets regular updates, making it a favorite for users who prioritize security and like having control over their network setup.

Like its cousin, pfSense Plus, OPNsense isn’t for the faint of heart. It takes a fair amount of technical know-how to set up and maintain, which can be a dealbreaker for small businesses without dedicated IT help. The steep learning curve means it’s better suited for tech-savvy users or teams with outsourced IT support.

While OPNsense shines in the hands of the right user, it’s not the best match for small businesses that need something simple, affordable, and scalable. If you’ve got the expertise or a managed service provider to lean on, though, it could still be worth considering.

Why do small businesses need the best firewall?

Small businesses need the best firewall to block cyber threats and protect their data and operations. Cyberattacks are a growing problem, and small businesses are often easy targets. A firewall acts as a digital gatekeeper, keeping harmful traffic out while allowing legitimate activity. Without it, your business could face serious risks, from stolen data to costly downtime and lost customer trust.

What happens without a firewall?

Operating without a firewall almost assures hackers have unmitigated access to your data. They're able to steal sensitive information, install malicious software, or disrupt your systems entirely. These attacks can lead to:

• Customer or employee details, like passwords and credit card numbers, could be stolen.
• Malicious programs could damage your systems or hold your data hostage.
• Your team might be unable to work if systems are compromised.
• Cleaning up after an attack can be time-consuming and costly.
• A single breach can scare away customers who expect their information to be safe.

How a firewall protects your business

A firewall works by blocking harmful traffic and keeping out anyone who shouldn’t access your network. It acts as a barrier, allowing safe connections while stopping threats before they can cause damage.

Modern firewalls offer even more. They can include tools like VPNs to keep remote workers connected securely, AI-powered systems to spot new threats, and features that work with cloud platforms.

Using the best firewall for a small business helps protect your data, keep your network safe, and build trust with your customers. It’s a simple way to avoid problems and focus on growing your business.

Challenges of choosing a small business firewall

Picking the right firewall can feel like navigating a maze of tech jargon and endless options. From figuring out what features you actually need to avoid overpaying for tools you’ll never use, the process can be daunting. Let’s tackle the biggest obstacles and show how to break them down.

How much security do you really need?

The best firewall for small business doesn’t mean the most expensive or feature-packed option. Many small businesses waste money on advanced features designed for enterprises, only to leave them unused. Your security should match your risks—not someone else’s.

Start by identifying your needs. Do you process sensitive data or need secure remote access? Focus on firewalls with tools like VPN support and threat detection. If your setup is simple, go for a straightforward solution that’s affordable and reliable.

Will the firewall fit with my existing network?

The right firewall should work seamlessly with your current systems. If it doesn’t, you could be stuck with delays, technical headaches, and unnecessary costs. Plus, as your business grows, your firewall should adapt to handle more users and devices.

Choose a firewall that’s compatible with what you already have but flexible enough for future needs. Look for multi-device support, easy cloud integration, and scalability. A good fit now should still work a year—or five years—from today.

Is managing this firewall going to be a nightmare?

A firewall that’s hard to manage can create more problems than it solves. Small teams without dedicated IT staff don’t have time to troubleshoot clunky systems or manually update software. Complex setups can leave your network vulnerable simply because they’re too confusing to use.

Pick a firewall with an intuitive interface and features like automatic updates to save time. Many modern firewalls come with mobile apps or cloud-based dashboards, making management simple for non-tech users. If support matters, go with a brand known for responsive help.

Can small businesses afford strong firewalls?

Yes, high-quality firewalls can be budget-friendly. While some businesses overpay for tools they don’t need, others avoid buying a firewall altogether because they think it’s too expensive. Both choices leave you vulnerable to costly attacks that can hurt your bottom line.

Affordable firewalls with scalable pricing are out there. Many solutions offer entry-level plans, free trials, or tiered options that grow with your business. You can protect your network without overspending—just focus on what brings the most value to your operations.

Frequently asked questions

1. Can small businesses afford high-quality firewalls?

Yes, many affordable options offer enterprise-grade features tailored to smaller networks.

2. What’s the best firewall for remote teams?

Look for firewalls with strong VPN support, like the SonicWall TZ Series or Meter's solution.

3. Are hardware firewalls better than software firewalls?

Hardware firewalls are ideal for on-premise setups, while software solutions work well in cloud-based environments.

4. Can a free firewall provide enough security?

Free options exist but often lack advanced protection and updates. Paid options offer more peace of mind.

5. How often do firewalls need updating?

Regular updates are necessary to combat emerging threats. Check for devices with automatic update features.

6. How do I know if my firewall is working?

You can check your firewall’s activity logs or run a network security scan to see if it’s blocking threats. Many firewalls also have dashboards that show real-time protection updates.

7. Can a firewall stop phishing attacks?

Firewalls can block dangerous websites and suspicious traffic, but phishing often relies on people clicking bad links. To fight phishing, combine your firewall with email filters and train your team to spot fake emails.

8. Is switching to a new firewall difficult?

Switching doesn’t have to be hard. Many firewalls offer guides or support to make the process easier. Planning ahead and backing up your settings will help make the change smooth.
