Prompt Security
What ChatGPT, Claude, Gemini & Grok actually say · August 2026
Visit prompt.security ↗The verdict
Prompt Security appears in 1 AI-ranked category — best position #4 for llm security tool.
Near-tied with Cisco for enterprises, combining application runtime protection with agent monitoring, prompt-injection detection, data-leak prevention, policy enforcement, and visibility into employee AI usage.
Claude The most complete commercial coverage of the exfiltration half — DLP-style detection and redaction of PII, secrets, and proprietary data in both prompts and responses, plus injection defense for homegrown apps, agents, and MCP traffic, with SentinelOne's backing post-acquisition; near-tie with Prompt Shields below, ranked ahead because it addresses both halves of the question rather than detection only.
Where Prompt Security falls short, per the models
- GPT It is primarily an enterprise control plane rather than a lightweight, self-hosted developer component.
- Claude An enterprise platform with platform pricing and deployment overhead — overkill for a single app team that just needs an inline injection check.
