The market has shifted, but the valuation criteria have not.
Integration speed is the single strongest predictor of vendor effectiveness. Ask how quickly a vendor can support a newly adopted AI application. Anything beyond two weeks indicates a structural limitation.

Business context separates usable security platforms from expensive dashboards. “312 findings” is noise. “83 users can export PII to an unsanctioned AI tool” is actionable.
Quick Solution

Your standard RFP process will not help you evaluate AI security vendors. It was designed for an earlier era of software procurement, when adoption cycles were slow, integrations were relatively static, and vendors had months to prepare controlled demos. None of those assumptions will hold in today’s AI landscape.

Following a year where the global AI in cybersecurity market was estimated at $25.35 billion, the sector is maintaining a robust 24.4% annual growth rate as it heads toward a projected $93.75 billion by 2030. In response, nearly every security vendor now includes “AI security” in its pitch. The result is a crowded market where differentiation is masked by near-identical feature lists, and where commonly used evaluation criteria actively conceal the risks that matter most.

The real question is not which vendor supports the most integrations. It is which vendor can detect what employees adopted yesterday, translate that activity into business impact, and enforce policy before exposure turns into an incident. Most cannot. Standard RFPs are structurally incapable of revealing that.

What follows is an evaluation framework that can.

The framework that follows outlines the 12 questions to run in every AI security vendor demo, the five capability categories that determine real coverage, and the red flags that should end an evaluation immediately.

Why the Standard Checklist Fails

Traditional procurement processes emphasize compliance certifications, integration counts, and dashboard screenshots. In the context of AI security, these criteria miss the core issue entirely: AI tool adoption consistently outpaces security coverage.

An employee can connect a new AI tool to a business application in minutes. Vendors that rely on hard-coded integrations often require six to nine months to add support for a new application. The gap between what is adopted and what is visible to security is where shadow AI risk accumulates. An RFP that asks “how many applications do you support?” measures the wrong dimension. The more relevant question is how quickly a vendor can support what employees are adopting in real time.

The second failure is a lack of context. Most AI security tools generate technical outputs such as misconfiguration counts, permission flags, and policy violations. CISOs do not need more findings. They need findings translated into business impact so they can prioritize, escalate, and act. Vendors that fail to provide this context create alert fatigue rather than meaningful security outcomes.

The Five Capabilities That Determine Real Coverage

AI security vendors tend to cluster around five distinct capability areas. Most specialize in one or two while leaving the others partially or entirely unaddressed. Understanding this full capability landscape helps prevent organizations from purchasing a point solution and mistaking it for a comprehensive program.

Capability What It Addresses The Evaluation Test
1. Shadow AI Discovery Unauthorized AI tools are used by employees without IT approval Can it detect AI tools through OAuth and behavioral signals, or does it rely solely on pre-configured integrations?
2. Data Exposure Management What sensitive data flows to AI services, sanctioned or unsanctioned? Does the solution quantify exposure in financial terms, or does it only surface technical policy violations?
3. AI Governance Policy enforcement, access control, and usage auditing Are policies adaptive based on the AI tool and data type, or are they limited to blanket allow or block controls?
4. Threat Detection Anomalous AI usage patterns, lateral movement, and behavioral deviation Does it reduce false positives, or does it simply add AI branding to existing detection mechanisms?
5. Agentic AI Security AI agents operating autonomously across SaaS apps Does the solution monitor agent actions and permissions, or does it assume agents are sanctioned by default?

The Evaluation Scorecard

Before your next vendor demo, use the three-tier framework below to score each response. “Best in class” should be the minimum bar. Any response below that threshold warrants a follow-up question or should end the evaluation.

12 Questions to Run in Every Demo

These questions are ranked by predictive value rather than vendor comfort. The first two alone will disqualify more vendors than all remaining questions combined.

Discovery and Coverage

  1. How do you detect AI tools that are not in your integration library? Look for OAuth monitoring, behavioral analysis, and API tracking. If detection depends on the tool being pre-identified, it cannot surface shadow AI.
  2. What is your timeline to support a new AI application? Best in class is 3 to 5 days. A quarterly release cycle is unacceptable. This metric is one of the most reliable indicators of real-world coverage gaps.
  3. Show a discovery from a live customer environment, not a demo tenant. Synthetic data in a demo suggests the product is not production-ready. It also signals that the sales team is aware of that limitation.

Detection and Response

  1. What is your mean time to detect a new shadow AI connection? Minutes is the benchmark. A "next scan cycle" response creates unacceptable exposure windows.
  2. How do you translate a finding into business impact? Ask to see a real alert. If it does not quantify financial exposure, it is a technical output presented as a security signal.
  3. Can you demonstrate false positive reduction? Ask for customer metrics. Increasing alert volume without improving accuracy makes security operations harder, not more effective.

Governance and Compliance

  1. How do you handle AI tools that process data across jurisdictions? GDPR, CCPA, and sector regulations require granular controls. "We support compliance" is not a sufficient answer.
  2. Can you enforce different policies for different AI tools? Not all AI tools present equal risk. Governance that treats an enterprise coding assistant the same as an unknown consumer application has not fully addressed the problem.
  3. What does an audit report look like? Ask to see an actual report. Regulators increasingly require demonstrable AI governance. Marketing screenshots do not meet audit requirements.

Architecture and Honesty

  1. How does your deployment model affect detection latency? API-based, agent-based, and network-based approaches each involve real tradeoffs. Understand what aligns with your environment before committing.
  2. How does this integrate with your existing security stack? SIEM, SOAR, and ticketing systems should be part of the workflow. Standalone tools create operational silos. Ask for a working integration demonstration.
  3. What do you miss, and how would we know? Every vendor has blind spots. Honest vendors are willing to name them. Those who will not have either failed to identify their blind spots or are choosing not to disclose them.

Red Flags: When to End the Conversation

Immediate Disqualifiers

  • Cannot provide customer references in your industry vertical
  • Demo uses synthetic data, refuses to show a real customer environment
  • Integration timeline measured in quarters, not days or weeks
  • Claims 100% coverage or cannot name a specific limitation
  • Requires months of professional services before basic functionality works

Yellow Flags: Probe Before Proceeding

  • Recently pivoted to "AI security" from an unrelated product category
  • Roadmap includes capabilities that should already exist at their claimed maturity level
  • Case studies focus on deployment complexity, not security outcomes
  • Compliance certifications are listed without defining scope or applicability

The POC That Actually Tells You Something

Most POCs are designed to measure what vendors prefer to showcase. Structure yours around the gaps that are least likely to surface.

Week 1: Baseline Discovery 

How many AI tools does the solution identify in your environment that you were not previously aware of? That number represents your visibility gap.

Week 2: Introduce an Unknown AI Tool

Without notifying the vendor, connect a new AI tool to a business application via OAuth. Measure how long it takes to appear in the solution. This is your true detection window.

Week 3: Assess Alert Quality

For each finding that has surfaced, determine what action is required and whether the associated business impact is clear. High-volume outputs with little context fail this test.

Week 4: Operational Fit

Can your team operate the solution without a dedicated analyst? Does it integrate into existing workflows, or does it require a parallel process?

How Reco Approaches This

Reco was designed to address the discovery gap inherent in AI tool adoption. The solution continuously monitors OAuth authorizations, API connections, SaaS logs, and behavioral patterns. When an employee connects a new AI tool, it becomes visible within minutes rather than at the next scheduled audit. The App Factory adds support for new applications within 3 to 5 days, closing the gap between adoption and security visibility before it turns into exposure.

The Knowledge Graph translates each finding into a business context, including the user involved, the affected application, the data accessible, and the associated financial exposure. This distinction separates operational dashboards from tools that support real security decisions.

A good 76% of CISOs expect a material cyberattack within the next 12 months. Vendors that can provide accurate, real-time visibility into current activity rather than retrospective reporting are the ones worth evaluating seriously.

Conclusion

Evaluating AI security vendors requires a shift in mindset as much as a shift in process. Static checklists and feature comparisons cannot keep pace with tools that are adopted and connected in real time, often outside formal approval paths. CISOs need evaluation frameworks that expose visibility gaps, quantify business impact, and surface operational limitations early in the buying process.

The goal is not comprehensive coverage on paper, but actionable coverage in practice. Platforms such as Reco, which emphasize rapid discovery, contextual risk analysis, and operational integration, reflect the direction this category is moving. In a landscape defined by speed and autonomy, the ability to see what is happening now matters more than promises about what might be supported later.
