Reassuring the regulators Share Copy Microsoft has unveiled a preview of Azure Firewall Premium, aimed at highly sensitive and regulated environments. Azure Firewall was Microsoft's attempt to sling a virtual arm over the shoulders of harassed administrators while whispering "there now, don't worry about all that pesky firewall configuration stuff, let us take care of it" in its most seductive tone. The result was a managed network security service, based in Microsoft's cloud, built to protect Azure Virtual Network resources from miscreants. Azure to on-premises traffic filtering was also supported. The Premium version, which is very much a preview and thus not recommended for production workloads, ups the ante with extra features.
