We have released a Security FAQ to help answer some of the questions that customers have brought to us regarding the security implications and best practices using the Performance Advisor for PTC Creo.
The article can be found here (requires a support login)
We decided to publish this as an article to make it easy to update as we get additional questions and comments, as well as making it easy to search for on our knowledge base.
If anyone has any additional questions or comments regarding security of the product or the FAQ in particular, this would be a good place to discuss. I can answer questions as best I can and update the FAQ for other customers to find answers.
