Yes, small businesses need firewall protection. A firewall helps control network traffic and block unauthorized connections. The right setup depends on your computers, office network, and remote workers.
A firewall cannot stop every threat. Use it alongside software updates, multifactor authentication, antivirus protection, backups, and employee training.
How A Firewall Works
A firewall checks incoming and outgoing network traffic against security rules. It allows permitted connections and blocks connections that do not meet those rules.
Depending on its features and configuration, a firewall can help:
- Block unauthorized network connections.
- Limit access between parts of your network.
- Filter access to potentially harmful websites.
- Record network activity for troubleshooting and security reviews.
A firewall cannot guarantee that malware or attackers will never reach your systems.
Choosing Firewall Protection for Your Business
Device firewalls protect individual computers, while a network firewall controls traffic between networks, such as your office network and the internet. These protections can work together.
Ask your IT provider:
- Are firewalls enabled on all business computers?
- Does our office network need a separate firewall?
- How are remote workers protected?
- Who manages updates, security rules, and alerts?
- Is our current equipment still supported by its manufacturer?
Choose protection based on your business’s needs and who will maintain it.
Does a Cloud-Based Business Still Need a Firewall?
Yes. Using cloud services does not remove the need to protect the computers and networks your employees use to access them.
Keep device firewalls enabled on business computers, including those used remotely. Ask your IT provider whether your office network also needs a separate firewall.
Protect cloud accounts with multifactor authentication and appropriate access permissions. A firewall alone cannot prevent someone from signing in with stolen credentials.
Network Visibility and Access Controls
Depending on its features and configuration, a firewall can record network activity and help your IT provider investigate blocked connections or unusual traffic.
Some firewalls also offer website and application filtering. These controls can help enforce your business’s internet-use policy. Ask which features are included in your plan and who reviews the logs and alerts.
Keep Your Firewall Updated
Install manufacturer-recommended updates and review firewall rules when your devices, applications, or staff change. Replace equipment that no longer receives security updates.
Assign someone to manage updates, review alerts, and remove unnecessary access rules. If an IT provider handles this, confirm what maintenance your agreement includes.
