FWaaS relocates the functions of a traditional firewall (also known as a security gateway appliance) to the cloud.
“As more organizations adopt cloud services and introduce hybrid cloud environments, the traditional network boundary has moved, and the security perimeter must now be extended into the cloud,” says Micki Boland, cybersecurity architect and evangelist in the Office of the CTO at Check Point Software Technologies.

What Are the Advantages of FWaaS Versus a Traditional Firewall?
Given the architecture underlying the modern IT infrastructure, a cloud-based firewall has several advantages over the conventional gateway appliance.
“When employees of state and local governments access data today, a lot of it is in the cloud. It’s no longer on-premises,” says Mike Goldgof, vice president of product marketing at Barracuda. “FWaaS moves the protection to be closer to the data sources.”
Likewise, “hybrid work is the reality today. We connect from anywhere,” Goldgof says. “In that environment, FWaaS moves the firewall protection as close to the user as possible.”
FWaaS is also more flexible than conventional firewalls. It provides “unified enterprise-class security policy with maximum agility,” Boland says. “Unlike physical firewalls limited by geographic constraints, FWaaS can be deployed anywhere due to its cloud-based nature.”
It also offers simplified deployment and management. Shifting the budget from a capital expenditure to an operational expenditure by using a tool that is virtualized and managed in the cloud “eliminates the complex process of purchasing, deploying and configuring physical firewalls,” she says.
A cloud-based approach offers inherent flexibility in response to ever-changing cybersecurity needs.
“FWaaS allows for flexible scaling of firewall resources based on demand. Unlike traditional firewalls, which often have fixed capacity limitations, FWaaS can dynamically adjust to accommodate changes in network traffic and infrastructure size,” Mehat says.
Compared with conventional firewalls, FWaaS also eases the burden on IT teams, because its vendors “are responsible for ensuring the availability, performance, and security of the firewall infrastructure,” she says. “This includes performing regular updates, patches and maintenance activities to protect against emerging threats and vulnerabilities, relieving organizations of the burden of managing these tasks internally.”

How Does FWaaS Benefit State and Local Government?
For government cybersecurity teams that are already are stretched thin, FWaaS offers a number of key benefits.
Managing conventional firewalls “is very complex. The firewall is there to set rules and policies to protect against certain traffic, and when you have traditional firewalls deployed on-premises, you have to make sure that all of those rules are set the right way for every location,” Goldgof says.
With FWaaS, “you are removing complexity that’s involved with managing firewalls,” he says. “FWaaS is easy to use, easy to manage, with one interface for all the applications. Central management capabilities are key. It’s much easier when everything is in the cloud and is managed once, not a hundred times.”
