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.

The Best Hardware Firewalls for your Small Business

1. Perimeter 81 – GET DEMO

Perimeter81

Perimeter 81 is an advanced security package that is hosted on the cloud. The system offers you the opportunity to fence individual applications as well as sites, which is a good way to deal with the security requirements of businesses that use cloud-based services, such as Microsoft 365 as well as on-site resources.

Key Features:

  • Cloud and On-site Resource Protection: Provides comprehensive protection for both cloud services and on-site resources, addressing the security needs of modern businesses.
  • Malware Filtering: Offers a malware filter for geographically dispersed organizations, ensuring thorough protection against malicious threats.

Why do we recommend it?

Perimeter 81 distinguishes itself as a leading cloud-hosted security package, offering robust protection for both cloud services and on-site resources. Its comprehensive security features, including malware filtering, Zero Trust Access implementation, and secure access service edge (SASE) system creation, make it an indispensable solution for businesses seeking to bolster their security posture. With the ability to scan traffic at Layers 3 and 4, Perimeter 81 ensures thorough protection against a wide range of cyber threats, providing peace of mind to organizations of all sizes. Additionally, its user-friendly interface and flexible deployment options make it easy to implement and manage, further solidifying its position as a top choice for cloud-based security solutions. Our recommendation of Perimeter 81 is rooted in its proven track record of effectively addressing the diverse security needs of businesses, whether they rely on cloud-based services like Microsoft 365 or utilize on-site resources.

The Firewall-as-a-Service module isn’t available in the lowest package of Perimeter 81, but it is offered in the three upper editions. The system works as a security policy enforcement system, which essentially, operates like the access control lists (ACLs) that you implement on routers.

Who is it recommended for?

Perimeter 81 is recommended for businesses across various industries seeking reliable and scalable cloud-based security solutions. Its flexible features cater to the needs of small networks, enterprises, and managed service providers (MSPs), offering tailored security solutions for diverse organizational requirements. Whether you're looking to enhance security for cloud services, on-site resources, or both, Perimeter 81 provides the tools necessary to create a secure and resilient network infrastructure. From safeguarding sensitive data to ensuring secure connectivity for distributed organizations, Perimeter 81 offers comprehensive security features suitable for businesses of all sizes. With its intuitive interface and multi-site management capabilities, Perimeter 81 is an ideal choice for organizations looking to streamline their security operations and mitigate cyber risks effectively.

Pros:

  • Flexible Features: Offers flexible features and packages suitable for both smaller networks and enterprises, catering to diverse organizational needs.

  • Easy Configuration: Object-based configurations make it easy to configure and manage security policies, reducing complexity and administrative overhead.

Cons:

  • Limited Trial Availability: Users express a desire for a trial option rather than a demo, allowing for more extensive evaluation and testing before committing to a purchase.

There are four editions for Perimeter 81. These are:

  • Essentials: $8 per user/month + $40/month per gateway, minimum of 10 users – doesn’t include FWaaS
  • Premium: $12 per user/month + $40/month per gateway, minimum of 10 users
  • Premium Plus: $16 per user/month + $40/month per gateway, minimum of 20 users
  • Enterprise: Custom service with a negotiated price, minimum of 50 users

EDITOR'S CHOICE

Perimeter 81 is our top pick for a small business firewall because it doesn’t require the upfront costs of buying a physical device and you don’t even need to install any software to use this system. The FWaaS isn’t the primary element of the Perimeter 81 package and it isn’t included in the cheapest edition, rather it is an element in a package of tools that let you implement a virtual secure network in a SASE configuration or apply application-level security in a ZTA implementation.
