Barracuda Networks is going deeper into the Microsoft (MSFT) Windows Azure world with additional integration between its Web Application Firewall offering and the Microsoft cloud platform.

Deployable as a single instance or as part of a scalable security platform, Barracuda Web Application Firewall is a cloud-based security offering that blocks an ever-growing list of web-based intrustions and attacks that target applications hosted on web servers and in the cloud.

In February, Barracuda announced a strategic relationship with Microsoft to bring its security-as-a-service offering to the Windows Azure cloud to secure applications running on the Microsoft public cloud. Back then, the two vendors noted that the partnership would make it possible for apps developers to secure their cloud apps with the same protection levels found in the most security-conscious on-premise data centers (with or without the assault rifles, I wonder?).

"The Barracuda Web Application Firewall provides a security solution for organizations migrating applications to Windows Azure," said Michael Van Bruinisse, vice president of business development at Barracuda Networks, in a prepared statement. "The advanced security capabilities of our Web Application Firewall ensure that applications and the associated data are protected from malicious threats."

Security, of course, remains a top-of-mind concern for technology decision-makers at all businesses, even if it's not quite the headline-grabber it used to be when cloud skepticism was running rampant.

Barracuda and Microsoft are aiming to make it easier for developers to launch apps and feel safe and secure in using Windows Azure.

"Windows Azure is a global, scalable and reliable cloud platform, and Microsoft has focused strongly on keeping customers' data safe and secure," said Karri Alexion-Tiernan, director of Windows Azure marketing at Microsoft, in a prepared statement. "We are excited to support Barracuda's Web Application Firewall in Windows Azure to provide additional security for our joint customers' applications and data."
