Firewall as a Service

A firewall in a computer network (hardware, software, or both) operates as a barrier to prevent unwanted access to the network, just like a fire-resistant wall does in a structure. The proactive monitoring of all incoming and outgoing traffic, along with the enforcement of security policies, are the means by which it accomplishes this goal.

A Quick Insight on the concept of Firewall as a Service

As more and more businesses migrated their applications and data to the cloud, firewalls were forced to adapt to their new role as a means of security. Cloud-based firewalls are now possible because to the introduction of firewall as a service (FWaaS).

Why Do Businesses Need It?

As companies are moving to the cloud, embraced Infrastructure as a Service, and rolled out more company and employee-owned mobile devices, they quickly realised that they no longer had clearly defined network perimeters. This was due to the fact that they were increasingly using applications and data hosted on third-party infrastructure (SaaS) rather than on their own infrastructure (IaaS and PaaS).

Their entire networks were no longer under their control because many of their apps and data were now hosted on third-party infrastructure. Firms learned that they couldn’t rely solely on their cloud providers to ensure their security in a cloud environment because both companies and cloud providers share responsibility for guaranteeing security. ¬†Many businesses were compelled to re-evaluate their security strategies as a result of this. As a result, they began utilising FWaaS to provide firewall and other network security capabilities as part of their cloud architecture as well.

Why Is FWaaS Essential for Businesses?

With FWaaS, users can outsource security inspections to the cloud in some or all cases. The hardware infrastructure that powers your solution is maintained by the cloud provider, who manages your solution’s security in the cloud. Your service agreement will include specifics defining the types of features you will have access to, depending on the subscription you choose. Having a service-based architecture allows companies to grow without having to worry about provisioning new hardware.

With so many firms having difficulty affording and managing hardware firewalls, FWaaS has emerged as an appealing alternative. It’s much easier for businesses to focus on other important tasks when they don’t have to worry about updating or adjusting settings because the service provider takes care of that.

It is possible for an organisation to scale security by connecting all of its scattered sites and users to a single, logical global firewall with an integrated security policy that is aware of the business’s applications. Even the largest organisations can benefit from the Firewall as a Service provider’s ability to provide access to a wide range of security resources, making it a viable option regardless of the size of the company.

While an on-premises wide-area network (WAN) infrastructure investment is required to implement an on-premises next-generation firewall, the costs associated with FWaaS make it an essential component of any SASE architecture. Upgrading your system on-premises necessitates investigating and comparing various components before making a purchase. Then, following the purchase of the item, the business must guarantee that its employees understand how it works, how to maintain it, and how to keep it updated. This is all taken care of by the service provider with FWaaS.

A full range of network security and inspection capabilities may be delivered on-demand for any user, wherever, thanks to FWaaS’s use of software and cloud technologies. With an in-house setup, your IT team has to keep aware of the latest software and technology changes impacting the realm of network security. FWaaS is needed by some firms to ensure that they have the most up-to-date protection. It is more likely that you will benefit from cutting-edge technology and approaches if your provider secures your network rather than your own in-house team.

Benefits of FWaaS

FWaaS has a number of significant advantages for firms looking for an agile security solution. FWaaS providers are becoming increasingly popular as a method for enterprises to keep their networks secure while allowing them to focus on their core business.

A single security strategy Cloud-based deployment

In order to achieve “unified security,” multiple security measures are brought together under a single guise. Because of this, the overall service is able to protect the company from a larger range of threats. There may be a deliberate redundancy in a unified security architecture due to many security solutions that can stop the same type of threat.

Your setup will go more smoothly if this is all done in the cloud. Every part of your unified architecture is handled by a service provider so that you don’t have to do any of that work on your own.

The Model of Flexible Deployment and Consumption

The implementation of an in-house solution might be time-consuming and complex. There are numerous moving pieces, both in terms of equipment and not. In contrast, the provider handles deployment in an FWaaS. Many times, this can be accomplished swiftly and with little to no involvement from management. When a certain configuration is required, the supplier merely needs the essential information from the company, and they may then tailor the deployment to their needs.

There are many ways in which FWaaS can help you get the most for your money while still providing the protection you require. For example, you can explain the problem to your FWaaS supplier and they can assist you in selecting the appropriate plan.

Reduced Time and Costs for Setup and Repair

An on-premises security suite or even a single security product can require a significant commitment in time and resources. Just tell your service provider what you want, and they’ll do the rest. They already have the resources they need, and they can handle all of the configuration details themselves.

Enhanced Capacity for Growth

Scaling your FWaaS solution is a cinch to do. All you have to do is bring up your new requirements with your service provider. Based on your company’s aims, they can then provide you with advice. The new method can be easily undone if it turns out to be overkill or unnecessary when scaling with an FWaaS.
