Firewalls have been a staple of almost every organization’s security since its inception in the late 80s. A firewall is a network security device that’s used to detect malicious traffic coming into and outside of a private network. But the dynamic nature of the evolving cyber landscape has forced organizations to migrate their security services into the cloud.
According to TechJury.net, 61% of businesses migrated their workload to the cloud in 2020. They also predict the public cloud market will be worth $800+ billion by 2025. With that being said, the data stored in the cloud needs protection. Along with Zero Trust security, having a cloud firewall is an integral part of a comprehensive cybersecurity plan. So, let’s look at the 5 main benefits of using a cloud firewall.
What is a Cloud Firewall?
To start, a cloud firewall is essentially the virtual version of a traditional firewall, but it’s cloud-deployed. You set up and define the rules and the cloud firewall will keep it from entering your network.
This type of security is extremely important once data is stored in the cloud. Currently, around 80% of companies have reported an increase in bots that are run by malicious actors attempting to steal sensitive company data. Having a cloud firewall in place can prevent malicious traffic from entering your website and keep your remote workforce safe.
Benefits of a Cloud Firewall
1: Cloud Firewalls Have Great Scalability
The main issue of a traditional firewall is that it cannot scale beyond its limitations. At a certain point, you’ll hit a bandwidth wall and have to perform upgrades. A cloud firewall scales as your business grows, so you can add more users and licenses at a later time without any disruptions to your IT and security stack.
2: Your Data Will Be Protected During Migration
When you are transferring data into the cloud, it’s at risk of being unprotected. A simple S3 bucket misconfiguration in an AWS cloud environment can lead to a massive data breach. A cloud firewall can be set up in cloud environments such as AWS or Azure to prevent misconfigurations and keep sensitive data from being leaked during cloud migration.
3: Cloud Firewalls Can be Deployed and Maintained Easily
Another benefit of a cloud firewall is that they are easy to install. The deployment process is fast since it’s software-based. Once deployed, everything can be managed with the click of a button, and any problems can be fixed directly through the cloud.
When it comes to maintenance, cloud firewalls make it very easy. The software will usually have a dashboard that can be used for managing the system. A cloud firewall is going to have an extensive list of tools that can be utilized to create refined filters and rules for controlling what moves in and out of the private cloud within minutes. It will integrate easily with your existing cloud infrastructure. That means you shouldn’t hit any bumps in the road during deployment.
4: Identity and Access Management
Admins are now able to set more granular policies and verify users across the organization with the identity and access management framework. This gives admins more granular control over who gets to access which applications to prevent any lateral movement within the network, leveraging the core principles of Zero Trust Network Access of eliminating implicit trust.
5: Cloud Firewalls Have Great Extensibility
One of the great advantages of a cloud firewall is that it can be managed from anywhere. Gone are the days of having to go to the office and tinker with the physical firewall device. Cloud firewalls can be deployed to protect your private network from anywhere in the world. When you have a traditional firewall, any updates and maintenance need to be done at the actual location of the device. This becomes a big problem for enterprises that have multiple branch locations with teams of employees and third parties spread out geographically.
The Bottom Line
To sum it up, there are many benefits to using a cloud firewall. Not only can it replace a traditional firewall and eliminate the need for a physical device, but it can also improve overall employee productivity and secure the hybrid workforce.
Up your network security game with a Firewall as a Service (FWaaS) and keep your corporate workflows protected from potential attacks.
