The tool ships free with no seat limits, so there's zero friction to run it across your entire web property before deciding on deeper GDPR or CCPA remediation tools. Skip this if your priority is blocking or rewriting scripts in real time; Website Privacy Test finds the problem, it doesn't fix it.

The tool maps asset inventory and risk posture from passive reconnaissance alone, covering NIST ID.AM and ID.RA functions that most pre-sales tools skip entirely. Skip this if your sales cycle assumes prospects will cooperate with formal scoping calls; Qontrol is built for the outbound motion where friction kills deals before they start.
