Firewalls – More than what you think

A firewall is the first line of defense on any network. Whether software, virtual, as-a-Service, or hardware-based, this network security component is vital for protecting your network from threats.

What many people neglect about firewalls (refer to the diagram below) is that they do not only protect an internal network from external threats coming from public networks (inbound traffic), but they also protect the outbound traffic from leaving an internal network. For instance, a firewall stops Malware or any application from opening ports and establishing communication to the outside. But it also protects internal networks from unknown and unwanted external traffic.

The firewall monitors both inbound and outbound traffic. It either blocks (discards packets) or allows them to go through using a list of predefined rules. 

Inbound - Outbound Firewall

How to Choose the Right Firewall?

Why Should a Small Business Use a Firewall?

Unfortunately, most businesses implement cybersecurity measurements until it is too late. They suffer from an incident—a data breach, Malware infection, an intrusion, or even a DDoS attack, and thus learn from mistakes. According to the Accenture Cost of Cybercrime report, 43% of the cyber attacks are aimed at small businesses. And what's more surprising is that only 14% are prepared with suitable cybersecurity measures to defend themselves.

And precisely, these stats are what attract hackers to target small offices and remote locations. —they are easy targets, which usually have poor (or no security) measurements.

Which type of firewall should a Small Business go for?

If you are on your quest to purchase a commercial-grade firewall to secure your network, you may have crossed paths on a few alternatives, especially software or hardware-based.

Which one to choose?

Well, it all depends on what assets are you protecting? And from what are you protecting them from?

You can install a software-based firewall to protect your PC or mobile from outside threats. But a software-based firewall will be limited to its host. On the other hand, a hardware firewall protects all devices, including workstations, mobiles, printers, lock systems, IoT devices, or anything connected to the network. Plus, hardware firewalls have a much higher performance than software.

What to Look For in a Hardware Firewall Device?

When looking for a small office home office firewall, consider getting an “entry-level” hardware firewall suitable for 50 endpoints (as a small office network size ranges between 25-50 endpoints). In addition, look for small form factor appliances designed for small spaces. At the basic level, firewalls should always provide packet filtering or stateful inspection.

The following are some additional features, capabilities, or options to look for in modern firewalls:

  • Next-Generation Firewalls (NGFW) perform the standard tasks of a regular firewall but can filter packets at the application layer (7) or DPI. These firewalls have more control and visibility on applications. NGFWs solve certain deficiencies of Unified Threat Management (UTM) platforms.
  • Secure SD-WAN Some innovative firewalls provide secure Software-Defined WAN (SDWAN) to connect branch offices to headquarters and provide additional WAN failover and security at a lower cost.
  • Zero-touch provisioning This feature allows users to simplify and even automate the onboarding of a new firewall.
  • VPN A firewall with VPN capabilities allows creating site-to-site VPN tunnels across the Internet.
  • Cloud services Most modern firewalls work with additional cloud-based services delivered as as-a-Service, SASE, or SD-WAN services.
