You already have security tools.
Where does AI governance fit?
Most CISOs are not asking what is the best AI governance vendor. They are asking whether they need one if they already have Zscaler, Purview, or Nightfall. This guide answers that, by stack.
Pick the stack you already own
Most CISOs are not asking "what is the best AI governance vendor." They are asking "do I need one if I already have these tools." Pick the closest match.
You catch network-level traffic. Aona adds the browser layer your SSE cannot reach.
Purview governs data inside the M365 estate. AI tools live outside it.
DLP scans for sensitive data. Governance scans for risky AI behaviour.
Data security posture stops at the data layer. AI usage starts where DSPM ends.
EDR watches the endpoint. AI usage happens above it, in the browser.
Cloud posture manages your infrastructure. AI risk is a human-layer problem.
GRC documents policy. Aona enforces it at the moment of action.
Comparing pure-play AI security platforms. Here is how Aona stacks up.
Where every layer of your stack stops, and where AI governance starts
One matrix. Seven stack categories you may already own, eight controls that AI risk requires. Print it, paste it into a board memo, or use it to score your own gaps.
