Common questions
Is this a hacking course?
No. It is defensive: architecture, standards, risk, inventory, response and governance. The testing module covers how authorised assessments are scoped safely, not how to attack a plant.
Who is it for?
Automation engineers, IT staff moving into OT, and anyone preparing for ISA/IEC 62443 certificates.
How long is it?
Long: about forty hours of video, because Mike Holcomb's course alone is twenty. Take it a module a week.
Is the course really free?
Yes. Every module, practice task and assessment. You create an account so your progress is saved and the assessments can be marked. The certificate is the only paid item, and only if you want it.
What certificate do I get, and is it a vendor qualification?
An EDWartens Certificate of Completion, issued when you pass the final assessment, with a verification code anyone can check. It is not a vendor credential and is never described as one.
