Quality and security improvements drive user satisfaction

We have many customers, but with Parasoft SOAtest, we just focus on .NET, Java, and PHP protocols and message formats. For deployment, it runs on-premise with Parasoft SOAtest. The transition from manual testing can be challenging, and it's the first time they're using automation testing with Parasoft SOAtest. For the tool itself, Parasoft SOAtest, I would rate it as great with an overall rating of 10 out of 10.
