Questions
Before you ask.
- What is a credit?
- One question asked of your system. Studio estimates a run's size before you start it.
- What happens when credits run out mid run?
- The run pauses and keeps its place for 30 days. Top up and it continues where it stopped; nothing is asked or charged twice.
- Do you see my data?
- Only the questions Plimsoll asks and your system's replies. Results stay in your project.
- Can I test a system on a private network?
- Yes, with Plimsoll Link, an outbound only connector, or an on premises appliance on Enterprise.
- Is a passport free for reviewers?
- Yes. The vendor sends a share link, and anyone checks it at plimsollsi.com/verify with no account.
