CST VerdictShort answer
Enterprise security teams drowning in shadow AI deployments need Manifest AI Bill of Materials to actually inventory what's running across the organization; most don't know where their models and training data live, and AIBOM forces that visibility at scale. The tool maps directly to NIST CSF 2.0's asset management and supply chain risk functions, two areas most enterprises fail because they treat AI systems like software when they're fundamentally different beasts. Skip this if your organization has fewer than 500 employees or hasn't shipped an AI application yet; the complexity tax only pays off when you're managing dozens of models across multiple teams. Mid-market and enterprise security teams drowning in shadow AI will find Portal26's real value in its discovery engine, which actually catalogs unauthorized GenAI tool use across your organization instead of assuming you know what's running. The platform covers eight NIST CSF 2.0 functions from asset management through continuous monitoring, with particular strength in the ID and DE domains that let you find what you're missing before it becomes a breach. Skip this if your GenAI governance strategy is still "trust our policy document"; Portal26 assumes you need enforcement teeth, not another framework.
