Microsoft today announced that Azure App Service, its cloud service for building websites and mobile apps, now features web vulnerability scanning to ensure that apps are secure as developers build and update them.

The new feature, which is available today, comes courtesy of startup Tinfoil Security.

“Microsoft Azure App Service chose Tinfoil Security because they are a trusted name in web application security and offer a strong set of services that will help our customers keep their web apps secure,” Microsoft Azure Websites software engineer Nazim Lala wrote in a blog post today on the news.

It’s the latest addition to the Microsoft Azure public cloud, which has been steadily growing but remains in the shadow of public cloud market leader Amazon Web Services. Interestingly, Tinfoil Security is available in the AWS Marketplace.

You can sign up for the new feature through the Azure Management Portal.
