No content logs
How it works
From prompt to secure output
Three steps. Sub-10ms inspection. Zero change to how your developers write prompts.
-
01
Write or call
A developer writes a prompt - or your app, agent, or workflow sends an API call to OpenAI, Claude, Gemini, Bedrock, Ollama, LangChain, or any compatible endpoint.
-
02
Inspect locally
PromptGate desktop client or universal proxy scans with zero-latency local models - PII, secrets, proprietary IP, and policy violations never leave your perimeter.
-
03
Forward safely
The sanitized prompt is forwarded to the provider. Blocked requests stay local. Your team keeps shipping - securely.

Performance & Velocity
Zero Latency Overhead. Uncompromised Engineering Velocity.
Traditional cloud proxies route sensitive payloads through distant third-party servers - introducing noticeable lag, breaking streaming responses, and frustrating developers.
PromptGate executes inspections locally at the edge / desktop engine before the payload leaves the machine. Developers get real-time token streaming and prompt responses with practically imperceptible, near-zero overhead.

LLM Stream
Edge & Local Evaluation
Heavy payload parsing runs directly on your perimeter, avoiding round-trip cloud bottlenecks.
Native Token Streaming
Seamless pass-through streaming for ChatGPT, Claude, and internal APIs without buffering or UI stutter.
Invisible to Engineers
Works transparently in the background with zero disruption to daily developer workflows.
Why PromptGate
Why Security Teams and Engineering Leads Choose PromptGate
Enterprise-grade LLM governance without compromising engineering velocity or agility.
Zero Added Latency (Edge & Local DLP)
Unlike cloud-based proxy bottlenecks that add 300ms+ per request, our local models inspect payloads in single-digit milliseconds. Developers won't even notice it's there.
Universal AI & Agent Support (Not Just One Provider)
Complete compatibility across every LLM framework and provider: Anthropic Claude, OpenAI, Google Gemini, Bedrock, Ollama, and autonomous AI agents (LangChain, AutoGen, CrewAI). Seamless plug-and-play.
Zero Data Retention by Design
PromptGate never stores your confidential prompts or raw completions. All telemetry is aggregated as anonymized counters and audit metadata. Your data remains strictly yours.
Unmatched Agility & Customer-First Support
Custom enterprise DLP rules, dedicated Slack channel with our core engineers, and custom regional detection packs tailored directly to your team's exact stack within 48 hours.
