1. Perimeter 81 FWaaS EDITOR’S CHOICE

Perimeter 81 FWaaS

Perimeter 81 produces a range of edge services, including its Firewall-as-a-Service (FWaaS). The FWaaS concept has many advantages over onsite firewall appliances. You don’t need to house, power, maintain, or protect the Perimeter 81 system – all of the hosting and management of the firewall is taken care of by the Perimeter 81 staff.

Key Features:

  • Enforces traffic encryption
  • Implements Single Sign On and 2FA
  • Covers multiple sites and remote workers
  • Software maintenance included in the price

Why do we recommend it?

Perimeter81 FWaaS is part of a cloud-based package that offers solutions for new strategies for corporate security that combine protection for on-premises applications and SaaS packages with user access control management. This system can also be used to create an SD-WAN and the FWaaS completes the package’s SASE solution.

The FWaaS architecture is an interesting proposition for all sizes and configurations of enterprises. Small businesses probably don’t have a very complicated network and wouldn’t have the expertise on-site to manage a comprehensive firewall. The Perimeter 81 system gives those small enterprises the full protection level experienced by big businesses, without any of the hassles of having to look after a complicated piece of equipment.

Larger businesses would also benefit from the Perimeter 81 FWaaS because it enables the protection of networks on multiple sites to be integrated into one service – watched from one single console. For businesses that prioritize IT service centralization, this is a very interesting option.

Perimeter 81 FWaaS add service


Flexible, innovative businesses that practice a virtual office strategy would be particularly interested in the Perimeter 81 FWaaS. If your business doesn’t operate any premises and uses freelance remote workers, then the task of linking all of those endpoints together into a secure whole can be problematic.

Who is it recommended for?

This system is a platform of tools that is available in four plans. The lowest plan, Essentials provides a corporate VPN package. You need to get one of the three upper plans to access the FWaaS option. The tools in the package allow a number of different system security strategies to be adopted.


  • Flexible features and offers that cater to smaller networks as well as enterprises
  • Multi-site management makes this viable for MSPs
  • Easy-to-use object-based configurations


  • Would like to see a trial as opposed to a demo

The FWaaS is an edge service and it fronts all of your business’s communications with the world, so it is able to present a single entry point to front a distributed workforce. Request a demo to get started.


Perimeter 81 FWaaS is our top pick for a NextGen firewall because it has all of the advantages of a cloud service while fully protecting your endpoints and services no matter where in the world they are located. The FWaaS is located away from your network and protects the link from its base through to your facilities with encryption. This service also manages secure connections between all of your sites, providing one entry point for a distributed business.

Next-gen firewall FAQs

What is the difference between UTM and next-generation firewall NGFW?

A next-generation firewall adds new functions to the traditional firewall tasks of blocking inbound connection requests. These include packet inspection, application layer data examination, threat intelligence, and intrusion detection measures. UTM stands for Unified Threat Management and this is a system that combines the activities of different security tools operating on a network. A firewall will be part of a UTM but it won’t include as many threat protection functions as a next-gen firewall.

Does NGFW have IPS?

IPS stands for “intrusion prevention system.” An IPS is an intrusion detection system (IDS) with added responses to shut down malicious activities. A firewall has IDS capabilities. You wouldn’t expect a firewall to detect a threat and then just let its traffic through and so you can be sure that the firewall will have playbooks to block intrusion. This makes a next-gen firewall an IPS system.

What layer does a NGFW use?

A next-generation firewall is an Application Layer tool, which is Layer 7. This is because a NGFW examines traffic across packets, so it is more than a Network Layer tool that would only be concerned with individual packets. It is also more than a Session Layer tool because it examines the contents of the packets. It is also higher than the Data Layer because the system deals with intent and function rather than just data, so it operates at the top layer of the OSI stack.
