Firewall as a Service Providers (FWaaS) are pillars of enterprise network security. Security for networks is provided by a firewall. It keeps an eye on both incoming and outgoing network traffic, allowing or blocking data packets in accordance with its security policies.

Its goal is to put up a wall between your internal network and traffic coming from outside networks, such as the rest of the internet. 

This prevents malicious traffic, including that of hackers and viruses.

What is a firewall as a service?

Firewall as a Service (FWaaS) moves firewall functionality to the cloud instead of the traditional network perimeter. 

By leveraging cloud computing, an organization can reap a number of financial, network performance, and security benefits.

Firewalls were initially developed to safeguard local company networks, but as more businesses migrated their data and applications to the cloud, firewalls had to change.

Firewalls can now be provided as a component of a company’s cloud infrastructure due to “firewall as a service,” or FWaaS.

It has some distinct benefits, though, like the capacity to scale almost instantly to accommodate a growing network.

Which services are provided by the firewall?

The firewall provides the following services:

Static-packet filtering

  • It is a firewall with routing capabilities that can filter packets according to the packet’s fields and the rules set up by the administrator.

Circuit-level firewalls

  • It serves as a handshaking mechanism for trusted clients, servers, and untrusted hosts.

Proxy server

  • System for network security that defends application-layer message filtering.

Application server

  • It defends web applications against numerous application layer assaults, including cross-site scripting (XSS), SQL injection, and many others.


  • Many firewalls have a feature called network address translation (NAT) that converts between internal and external IP addresses.

Stateful packet inspection

  • Active connections are monitored by dynamic packet filtering, which chooses which network packets to let pass through the firewall.

Is the firewall IaaS or PaaS?

A platform-as-a-service (PaaS) or infrastructure-as-a-service (IaaS) model is used to run virtual firewalls, which are cloud-based services that are created to run in a virtual data center using your own servers.

In these situations, traffic to, from, and between cloud applications is protected by the firewall application, which is running on the virtual servers. 

IaaS/PaaS allows you to create, provision, and manage your own virtual servers using infrastructure that you rent from a service provider. 

The term “next-generation firewalls” is sometimes used by the industry to describe any advanced firewall system that runs on-premises or in the cloud, though it is not consistently used in that sense.

Frequently Asked Questions

What are the three types of firewalls?

Firewalls are typically your first line of defense against malware, viruses, and attackers trying to access your organization’s internal network and systems, whether they are implemented as hardware, software, or both. 

The way they function is another way to classify firewalls, and each type can be configured as either software or a physical device.
1. Packet Filtering Firewalls

The earliest and most fundamental type of firewalls are packet filtering firewalls.  Firewalls with packet filtering operate in a line at intersections where switches and routers are used. 
2. Circuit-Level Gateways

Circuit-level gateways monitor active sessions and confirm established Transmission Control Protocol (TCP) connections while operating at the session layer. The packets are not personally inspected by them.
3. Stateful inspection firewall

State-aware devices not only examine each packet, but also keep track of whether or not it is a part of a TCP or other network session that has already been established.

Why Do Companies Need FWaaS?

When it comes to security in the cloud, the cloud provider will manage your solution and the hardware infrastructure that powers it.

Because it allows them to grow as needed without worrying about provisioning new hardware, service-based architectures are necessary for many businesses.

Businesses must still provide enterprise firewall capabilities to all users and locations across the organization even as they use cloud infrastructure providers like AWS to increase scalability.

NGFWs go much further, offering extra functionality that makes it possible for a company to detect and thwart attempted cyberattacks more successfully.

With FWaaS, a company can scale security more effectively by connecting its distributed sites and users to a single, logical, global firewall with a unified application-aware security policy.
