CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Academic programs and corporate training teams need ACI Learning Skill Labs because it actually lets students break things hands-on instead of watching videos, which is the only way network and security fundamentals stick. The CollegePro sets align with real course calendars across years 1-2, and auto-grading cuts instructor overhead on repetitive validation work. This is built for schools and training departments, not for security operations teams looking to upskill existing staff on incident response or threat hunting; if your goal is certifications and foundational competency, this works; if you need role-specific depth for security engineers already in the field, look elsewhere.
Security teams building mobile testing programs or Android developers who need hands-on vulnerability labs should use InsecureBankv2 because it's free, maintained, and includes both client and backend components to practice real attack chains rather than isolated code snippets. The 1,417 GitHub stars and active contributor base signal a stable training environment that's been battle-tested by infosec programs for years. Skip this if your team needs guided curriculum or automated scoring; InsecureBankv2 is a sandbox, not a platform, and requires someone who already knows what they're looking for.
