What else should teams answer?

• How do I compare AI security vendors?
• What should go into an AI security RFP?
• How do I avoid comparing vendors that solve different problems?
• What proof should I ask vendors for?

Start with the AI workflow, not the vendor category

Buyers should define the AI workflow before comparing vendor labels. Start with the business problem: employee use of public AI, an internal assistant connected to company data, a customer-facing AI feature, an agent that takes actions, a software copilot, a model pipeline, or AI activity already happening without approval. Then define the control surface, the control outcome, the owners, and the evidence required. This prevents a common shortlist mistake: comparing vendors that use similar words but solve different problems.

Labels such as AI firewall, AI governance, AI data security, AI agent security, AI browser security, and AI security posture can be useful starting points, but they are not enough for procurement. A buyer may need visibility into employee use, policy enforcement in the browser, permission-aware retrieval for internal assistants, runtime checks for an application, or logs for security operations. Those are different buying problems even when vendors describe themselves with overlapping language.

Define the problem segment

AI Security Hunt uses problem segments to separate buyer needs. A problem segment describes the AI risk pattern the buyer is trying to control, such as employee AI use, sensitive data exposure, prompt injection, excessive agency, retrieval and vector data exposure, model supply chain, AI inventory, or framework mapping. The segment should be tied to a real workflow and a named owner.

A clear segment helps buyers avoid broad requests for proposals that attract every AI security pitch. It also helps teams include the right stakeholders. Employee AI use may involve legal, privacy, human resources, and works council considerations. Internal assistants may need data owners and identity teams. Agent controls may need operations leaders and process owners. Runtime application controls may need product security and engineering.

• Name the workflow and the business owner.
• State whether the goal is to deploy AI securely, secure AI already being used, or both.
• Define the risk event you are trying to reduce.
• List the internal teams that must approve, operate, or review the control.

Identify the control surface

The control surface is where a product can observe or influence AI activity. It may be the browser, endpoint, network proxy, software integration, application code, application programming interface gateway, data layer, model pipeline, identity layer, or security telemetry. Two vendors may both claim to prevent data leakage, but one may sit in the browser while another sits inside an AI application. They will see different activity, miss different paths, and produce different evidence.

Ask vendors to draw their control surface in your architecture. Where does the control sit? Which users and systems does it cover? Which paths are out of scope? Does it inspect prompts, files, retrieved context, model responses, tool calls, logs, or only final outputs? A shortlist should group vendors that can control the same relevant surface.

Define the control outcome

A control outcome is the result the buyer expects, such as visibility, policy enforcement, data leakage reduction, permission-aware retrieval, prompt injection resistance, output filtering, tool-use control, approval gating, logging, alerting, or evidence generation. Outcome language keeps the buying team focused on what the product must prove rather than how impressive the demo looks.

Use outcome language in the request for proposal. For example: demonstrate how the product detects customer data in prompts; show how permissions are enforced when the assistant retrieves documents; provide sample logs for an agent action; show how policy exceptions are approved; or map controls to an internal risk register. This is more useful than asking whether a vendor has a generic AI governance platform.

Separate enterprise readiness from funding stage

Funding stage is context, not proof. An early-stage vendor may be a strong fit for a focused problem if it has the right control surface, strong product evidence, responsive support, and a deployment model that matches your risk tolerance. A later-stage vendor may have broader operations, security reviews, legal support, and customer references, but still may not solve your specific workflow.

Enterprise readiness should be assessed directly. Ask about identity integration, administrative controls, audit logs, privacy settings, retention controls, security documentation, support model, deployment effort, change management, uptime expectations, and incident response. AI Security Hunt Verification, when present, can help structure diligence, but it should not replace buyer testing or internal approval.

Ask for proof before the demo

Before a demo, send a short proof request tied to your workflow. Ask for architecture diagrams, covered control surfaces, sample evidence, policy examples, integration requirements, false-positive handling, privacy controls, and limits. A prepared vendor should be able to respond without turning the conversation into a generic product tour.

The upcoming AI Security Vendor Map from AI Security Hunt is designed to help buyers organize this comparison across problem segments, control surfaces, control outcomes, enterprise readiness, AI Security Hunt Verification status, funding stage, and framework lenses. It is a map for shortlist preparation, not a substitute for buyer due diligence.

Practical shortlist checklist

• Write one paragraph describing the AI workflow and risk event.
• Choose the problem segment and name the internal owner.
• Identify the control surface that must be covered.
• Define three to five control outcomes the product must prove.
• List privacy, legal, employee monitoring, data, and security constraints.
• Ask vendors for evidence before scheduling demos.
• Separate product fit from enterprise readiness and funding stage.
• Use framework lenses where they help translate risk, but do not treat mapping as certification.
