No, there isn't.
Based on my experience with Symantec's cloud offering, it was designed to provide a limited amount of protection to a wide audience. Keep in mind, this is nothing more than the consumer-based Norton desktop product wrapped up in a "fancy" web front-end. The product's complete functionality is not available to you on the web; you have to open the GUI on the desktop. And even then, there is no way to script updates for an entire site; it is purely manual effort. You are completely at their mercy in terms of when - or even if - product updates occur, and the changes that they introduce to your environment. In other words: There is no way to test this cloud-based product in a development or test environment.
For an HA environment I would not use this product.
If you want to continue to use a Symantec security product, I suggest you incur the expense of the EE version. This will ensure that a) you get high-priority support immediately and b) you have a product that at least provides updates (I won't say on a regular basis) that you can test in a development or test environment before releasing to production.
Hope that helps!

You do NOT want an HA server to have to go through something like this...
