CST VerdictBased on our analysis of NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Enterprise security teams deploying large language models and generative AI systems need adversarial testing built into their release pipeline, and Dreadnode Spyglass is the dedicated tool for that job. The platform maps directly to NIST CSF 2.0's Risk Assessment and Adverse Event Analysis functions, letting you systematically probe AI vulnerabilities before they reach production rather than discovering them in the wild. Skip this if your org is still evaluating whether AI risk testing matters; Spyglass assumes you've already committed to red teaming as a control, not a nice-to-have.
Mid-market and enterprise security leaders responsible for AI supply chain risk will find Cranium Arena essential for the one thing most red teaming tools skip: continuous assessment of third-party and vendor models before they enter your stack. The platform maps findings directly to NIST AI RMF and EU AI Act requirements, eliminating the translation work between red team reports and compliance checkboxes. Skip this if your organization hasn't yet inventoried which AI systems you're actually using or if you're looking for general LLM jailbreak testing; Cranium Arena assumes you know what you're securing and why.
