"I got a notice I'm going to be examined."
A regulatory exam (SEC, FINRA, or your state securities division) arrives with a checklist. They want to see documentation of your cybersecurity controls: what you have in place, how you manage it, and what happens if something goes wrong.
H2Cyber walks you through 56 specific controls, produces a scored report with a letter grade, and gives you a document you can put in front of an examiner. You can complete it yourself at your own pace, or have a practitioner walk you through it.
