The Best Next-Gen Firewalls

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.

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. 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.

Key Features:

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


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 entrypoint for a distributed business.
