Cloud firewalls are virtual network security devices deployed in the public cloud. Public cloud firewalls tend to offer capabilities like those of hardware firewalls. However, in hybrid cloud deployments, public cloud firewalls offer significant advantages over on-premises devices in terms of scalability, availability, and extensibility. Often also called “virtual firewalls,” these devices are referred to as “public cloud firewalls” when used in those environments. Cloud firewalls block cyber-attacks directed at these cloud assets. As the name implies, a cloud firewall is a firewall that is hosted in the cloud. Cloud-based firewalls form a virtual barrier around cloud platforms, infrastructure, and applications, just as traditional firewalls form a barrier around an organization’s internal network. Deploying a cloud firewall is like replacing a local security camera and a physical security guard with a global 24/7 security center that has a centralized staff and security camera feeds from all the places.
As an organization’s cloud presence grows, public cloud firewalls scale gracefully by adding virtual instances, with no hardware installation or maintenance required. Even bandwidth-hogging threats, such as distributed denial-of-service (DDoS) attacks, can be mitigated quickly and effectively using public cloud firewalls. Public cloud firewalls work best when designed and configured to work in concert with the provider’s native security solutions, with no gaps. It is a best practice for an organization to procure public cloud firewalls from cybersecurity vendors who have jointly developed their solutions with the CSPs the organization intends to use.
