Vendor comparison
AI security vendors: how enterprise buyers should build a shortlist.
The AI security vendor market now spans edge security, guardrails, runtime defense, model supply chain, agent governance, and prompt-layer controls. Enterprise buyers need a shortlist method that maps vendors to the control surfaces they actually secure.
Control
Policy first
Map every AI interaction to allow, flag, mask, or block decisions.
Data
DLP aware
Detect sensitive prompts, regulated data, and document leakage risk.
Traffic
Gateway aligned
Apply controls before prompts reach external model providers.
Evidence
Audit ready
Keep explainable records for security, risk, and compliance reviews.
Shortlist criteria
Start with the layer where your AI risk actually appears.
PromptWall recommends comparing vendors across five dimensions: prompt firewall enforcement, AI DLP, secure provider routing, governance/audit, and rollout coverage. This avoids over-weighting broad platform language when the buying problem is prompt and data control.
Prompt
Prompt-layer controls
Inspect direct user prompts, retrieved context, tool requests, and unsafe instruction patterns.

DLP
Data protection controls
Detect, mask, flag, or block regulated data and confidential records before model dispatch.

Gateway
Gateway controls
Govern provider routing and keep policy consistent across OpenAI, Anthropic, Azure, Gemini, and internal models.

Vendor landscape
Use conservative comparisons and buyer-fit language.
Cloudflare is often evaluated for edge/app security and AI gateway visibility, Lakera for guardrails and prompt defense, Protect AI and HiddenLayer for broader AI security platform coverage, and Zenity for agentic AI governance. PromptWall should own the category language around prompt firewall, AI DLP, and LLM security layer controls.
