Who it suits

Editorial judgment
Beginners who want a practical, lab-based exam covering phishing analysis, SIEM, forensics and incident response, at a mid-range price.

Notes and caveats

The official page gives two time estimates: "approximately 30 hours to complete" in the course summary and "typically between 40 to 50 hours" in the FAQ. The provider states that on average 70% of students pass on their first attempt; that figure is the provider's own and is not independently verified. The former securityblueteam.io domain did not resolve on the check date.
