As organizations increasingly adopt cloud-based environments, cloud security is a growing concern as critical applications and sensitive data hosted in cloud environments are often more exposed to cyber threats than their on-premises counterparts.
Microsoft’s Azure Firewall is a cloud-native security solution for Azure environments. It provides traffic inspection, filtering, and monitoring. An upgrade to Azure Firewall Premium is also available, providing additional features to organizations with greater cloud security needs.
By deploying Azure Firewall, organizations with assets hosted in Azure can rapidly and easily provide fundamental protection of these assets against cyber threats.
Azure Firewall Premium is an upgrade designed for Azure environments containing highly sensitive and regulated data. It includes TLS inspection, an intrusion detection and prevention system (IDPS), URL filtering, and the ability to filter traffic based on web categories.
Azure Firewall is a virtual firewall implemented within the Azure Cloud environment. An organization can configure its Azure Firewall so that all traffic entering or leaving its cloud environment or moving from one spoke VNet to another passes through the firewall, where it is subject to analysis and filtering. The Azure Firewall can be monitored and managed via the Azure Monitor.
With the Premium version, the firewall gains the ability to terminate and inspect TLS connections and integrates an IDPS to provide threat prevention based on threat intelligence provided by Microsoft. This provides greater visibility and the ability to block known threats from entering an Azure cloud environment.
Microsoft’s Azure Firewall offers native protection to resources deployed in Azure cloud environments. However, both the standard and Premium versions have their limitations, including:
Azure Firewall provides a solid foundation for organizations wishing to protect their Azure-based resources. However, additional solutions are required to provide comprehensive protection against cloud security threats, especially for organizations with a multi-cloud strategy.
Azure Firewall is designed to provide a usable fundamental level of security for Azure cloud environments. Organizations looking to gain a higher level of visibility and control over the traffic entering and leaving their cloud can easily do so with Azure Firewall. By upgrading to Premium, they gain a level of threat prevention and visibility into the TLS-encrypted traffic streams that make up the majority of modern Internet traffic.
For organizations looking to protect multi-cloud environments or need functionality and advanced threat prevention beyond what Azure Firewall offers, Check Point’s CloudGuard provides the ability to enhance and complement the native security features built into Azure environments. Like Azure Firewall, CloudGuard is implemented as a cloud-native virtual appliance that enables organizations to take advantage of the full scalability and benefits of cloud-based environments with a solution tailored to Azure.
For organizations already using Check Point on-premises network security gateways, choosing CloudGuard for cloud network security should be a no-brainer, because it provides the same industry-leading threat prevention, is quickest to deploy due to reduced training and integrations, is easiest because it uses the same UI, processes and security policies as on-prem, has lowest risk compared to introducing new security solutions which may not work with their existing workloads, and enables lowest total cost of ownership because there is no need for new engineering staff to deploy and maintain the cloud security solution.
