Firewall as a Service (FWaaS) Providers: What To Look For

What is Firewall as a Service (FWaas)?

Firewall-as-a-Service, or FWaaS, is a cloud-based security solution that provides firewall functionality and network security to protect an organization’s network infrastructure.

FWaaS offers organizations a flexible, scalable, and cost-effective approach to network security by providing firewall functionality and additional security services through a cloud-based deployment model.

FWaaS is an integral component of the SASE framework and operates in conjunction with other services to provide comprehensive security and networking capabilities.

Firewall as a Service providers offer a range of services to enhance network security and protect organizations from cyber threats.

In this article, we review some of the top FWaaS service providers and how GTT’s FWaaS offering helps organizations expand their security capabilities in line with their evolving networks.

What Do Firewall-as-a-Service Providers Offer?

Firewall as a Service providers offer a range of services to enhance network security and protect organizations from cyber threats.

Here is what is typically featured by FWaaS providers:

  • Firewall configuration & deployment: FWaaS providers deploy comprehensive firewall protection, including edge security, application firewall protection and network firewalls. They configure the firewall infrastructure according to the specific needs of your organization.
  • Traffic monitoring: FWaaS providers use advanced technology to monitor network traffic passing through the FWaaS system or platform. This includes real-time inspection of network packets, session tracking, content filtering and analysis of application-level protocols.
  • Reporting and log management: FWaaS providers collect and store logs generated by the firewall system. The logs include information about network traffic, security events and policy violations. These are analyzed and presented in easy-to-understand report formats or dashboards.
  • Threat detection and protection: FWaaS providers employ intelligent threat detection, intrusion prevention systems (IPS), threat intelligence feeds, behavior analysis and anomaly detection techniques, proactively detecting and blocking malicious traffic.
  • Centralized management: Most advanced FWaaS systems include centralized management and policy control through a web-based interface. They provide a single- pane-of-glass view for rule management, policy enforcement and configuration changes across multiple firewall instances. This simplifies firewall administration and ensures consistent cybersecurity policies across the network.
  • Integrated SASE services: Some FWaaS providers offer integrated services as part of a Secure Access Service Edge (SASE) platform. SASE combines network security and wide-area networking (WAN) capabilities into a unified cloud-based service. These may include:
    • Firewall protection
    • VPN access
    • Secure web gateways (SWG)
    • Data loss prevention (DLP)
    • Cloud access security broker (CASB)
    • Secure DNS
    • Zero-trust network access (ZTNA)
    • Secure email gateways (SEG)

While these are the services most commonly offered by top FWaaS service providers, the specific service features often differ for different FWaaS providers.

It is best to assess your organization’s specific security requirements and match them to the bouquet of services offered by your preferred FWaaS vendor so that there is a tight alignment with your security objectives.

Characteristics of a Quality FWaaS Provider

There are several key characteristics that differentiate an FWaaS provider from traditional on-premises firewall solutions.

Here are some important characteristics of Firewall as a Service providers:

  • Cloud-native architecture: FWaaS is a service-based approach with cloud firewall capabilities delivered by third-party service providers. FWaaS providers leverage cloud infrastructure to provide security, eliminating physical, on-premises firewall appliances. In contrast, traditional firewall service providers offer hardware or software-based solutions that require installation and maintenance within the organization’s network infrastructure.
  • Enhanced security: FWaaS providers offer advanced security features and capabilities beyond traditional firewall solutions. These may include intrusion detection and prevention systems (IDS/IPS), advanced threat intelligence, malware detection, secure web gateways and other security layers. FWaaS providers continuously update their security measures to counter emerging threats effectively.
  • Centralized management and monitoring: FWaaS providers typically provide a centralized management interface to configure, monitor and control firewall settings and security policies from a single dashboard.
    • Traditional on-premises firewall solutions often involve multiple endpoint security devices and disparate firewall appliances, making it difficult to achieve integrated and comprehensive security capabilities that can be centrally managed or viewed as a unified dashboard.
  • Ease of maintenance: FWaaS providers handle the maintenance and updates of the entire firewall infrastructure, applying security patches, installing updates and upgrading to the latest threat intelligence and protection services. Traditional firewall solutions require your IT team to manage maintenance, updates and patches.

By leveraging cloud infrastructure, FWaaS providers offer scalability and cost efficiency with a modern and cohesive approach to network security that differentiates them from traditional on-premises firewall solution providers.
