The Best Next-Gen Firewalls

1. Perimeter 81 FWaaS (EDITOR’S CHOICE)

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:

• Traffic Encryption Enforcement: Guarantees the encryption of all traffic for heightened security.
• Unified Access Control: Implements Single Sign-On (SSO) and Two-Factor Authentication (2FA) to streamline and secure user access.
• Comprehensive Coverage: Extends protection across multiple sites and to remote workers, ensuring wide-ranging network security.
• Inclusive Software Maintenance: Offers software maintenance as part of the service package, eliminating additional costs and effort for businesses.

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.

 

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.

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.

2. Fortinet FortiGate
