By harnessing the power of the cloud, FWaaS offers unprecedented scalability, flexibility and centralized management, making it an essential tool for organizations looking to stay one step ahead of cyber attackers. In this blog post, we explore why FWaaS is not just a trend, but the future of cybersecurity and how it can provide the robust, adaptable protection organizations need today.
A. What is Firewall as a Service (FWaaS)?
Firewall as a Service (FWaaS) is a cloud-based firewall service that provides security features on a subscription basis. This means you don't have to buy and maintain your own physical firewall hardware or software, which can be expensive and complex to manage.
Instead , with FWaaS you can easily manage and protect your network by subscribing to a cloud-based firewall service from a provider. The provider usually takes care of installing, maintaining and updating the firewall for you and provides you with a user-friendly interface to manage your firewall rules and policies.
FWaaS can also provide advanced security features such as intrusion detection/prevention, VPN connectivity and content filtering, which can protect your network from a range of cyber threats. In addition, FWaaS can be easily scaled up or down to meet your changing network security needs, making it a flexible and cost-effective way to manage your network security.
B. 7 Differences between traditional firewall and FWaaS
- Deployment location: Cloud-based firewall, also known as cloud firewall, is deployed in the cloud. This means that it is managed and hosted by a third-party provider and that all firewall operations are performed over the internet.
- Scalability: High scalability: Cloud firewalls can be seamlessly adapted to the company's requirements. As they are cloud-based, capacity can be increased or new functions added quickly and without significant additional costs.
- Management and maintenance: Managed service: The service provider takes care of management and maintenance. This includes automatic updates, patches and round-the-clock monitoring, reducing the administrative burden on internal IT teams.
- Costs: operational expenditure: Typically operated on a subscription model, turning capital expenditure into a predictable monthly operating cost. This can be more cost-effective, especially for smaller organisations.
- Flexibility: Dynamic and adaptable: Cloud firewalls are inherently flexible, allowing for easy reconfiguration and adaptation to changing network environments. They can efficiently support remote and distributed workforces.
- Geographic reach: Global coverage: Cloud firewalls provide protection regardless of the user's location, making them ideal for organisations with multiple offices, remote workers and global operations.
- Advanced security features: Integrated solutions: Cloud firewalls often have a range of built-in advanced security features that can be easily enabled and managed as part of the service.
- Deployment location: On-site: Conventional firewalls are hardware or software appliances that are installed in a company's local network. They are located at the network boundary and monitor and control incoming and outgoing data traffic based on predefined security rules.
- Scalability: Limited scalability: Scaling a traditional firewall usually requires the purchase and installation of additional hardware, which can be costly and time-consuming.
- Management and maintenance: Local management: Requires on-site IT staff to manage, configure and update the firewall. This includes applying patches, updating hardware and dealing with maintenance issues.
- Costs: Capital expenditure: Significant upfront costs for purchasing hardware and software. Ongoing costs include maintenance, upgrades and staff to manage the system.
- Flexibility: Static infrastructure: Traditional firewalls are less flexible and difficult to reconfigure or move as the network architecture changes or the organisation expands geographically.
- Geographic reach: Single site: Typically serves a single physical location or network segment, which can be limiting for organisations with multiple locations or remote employees.
- Advanced security features: Limited by hardware: Adding advanced features such as Intrusion Detection and Prevention Systems (IDPS), Secure Web Gateways (SWG) or Data Loss Prevention (DLP) often requires additional hardware or software.
C. How does the firewall work as a service?
To understand how Firewall as a Service (FWaaS) works, you need to know how this cloud-based security solution is integrated into and protects an organisation's network infrastructure.
Unlike traditional firewalls that are installed on-site, FWaaS utilises the cloud to provide scalable and flexible security measures that ensure comprehensive protection for all digital assets.
-
Cloud deployment
FWaaS is hosted in the cloud, which means there are no physical firewall devices to manage or maintain on site. The firewall functions are provided via a cloud platform managed by the service provider.
-
Routing of data traffic
The network traffic is routed through the infrastructure of the FWaaS provider. This can include traffic from local systems, remote users and cloud-based applications. The service checks this traffic for threats and enforces security policies before forwarding it to its destination.
-
Centralised administration
FWaaS provides a centralised management console that is usually accessible via a web interface. Administrators can configure security policies, monitor traffic and manage firewall rules from a single location. This simplifies administration, especially for companies with distributed networks.
-
Scalability
As it is a cloud-based solution, FWaaS can be easily scaled to cope with increasing traffic volumes and growing business requirements. This scalability is often more cost-effective than upgrading physical firewall hardware.
-
Advanced security functionsFWaaS often includes advanced security features such as:
- Intrusion Detection and Prevention Systems (IDPS): Monitors network traffic for suspicious activity and can take action to block threats.
- Secure Web Gateway (SWG): Provides protection against web-based threats and enforces web access policies.
- Data Loss Prevention (DLP): Protects sensitive data by monitoring and controlling data transmissions.
- Zero Trust Network Access (ZTNA): Ensures that only authenticated and authorised users can access certain network resources.
-
Integration with other security services
FWaaS can be integrated with other cloud-based security services, such as Secure Access Service Edge (SASE) solutions, to create a comprehensive security posture. This integration helps to implement a layered defence strategy.
