10 Best Firewall as a Service (FWaaS) Providers – 2024

Firewall as a Service (FWaaS) is an emerging security model in cloud computing and network security. It represents a shift from traditional, on-premise firewall solutions to cloud-based firewall services.

Firewalls as Service Providers (FWaaS) are pillars of enterprise network security.

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 create a wall between your internal network and traffic 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 several 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 does the Firewall Provide?

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.
  • NAT: Many firewalls have a feature called network address translation (NAT) that converts between internal and external IP addresses.
  • Stateful packet inspection: Dynamic packet filtering chooses which network packets to allow through the firewall while keeping an eye on active connections.

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.

The firewall application, which runs on virtual servers in these circumstances, protects traffic to, from, and between cloud applications.

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.
