Constellation Gate AI

What it does

Constellation Gate AI is a drop-in security gateway for AI agents. It sits between your agent and the model, screening every request for prompt injections, secret leaks, and PII. It also compresses prompts and caches prefixes to save tokens automatically. Every decision is recorded on an immutable blockchain audit trail.

Who it is for

Gate is designed for developers and teams using AI agents—especially coding agents like Claude Code, Cursor, OpenClaw, Codex, and OpenCode. It works with any model API (Anthropic, OpenAI, Google, xAI, OpenRouter) and requires no code changes: just point your SDK at Gate's endpoint or use the Gate Connect desktop app.

Why it matters

Prompt injection is the #1 OWASP LLM risk for 2025. Relying on the model to defend itself is insufficient. Gate blocks attacks before they reach the model, redacts secrets before they leave, and stops indirect injections from hijacked tool calls. It also reduces token spend by 20%+ through lossless compression and prompt caching. The blockchain audit trail provides tamper-evident, independently verifiable records—useful for compliance, auditing, and zero-trust environments.

Launch signal

Gate ranks #1 across 16 public prompt-injection benchmarks with a 97.4% F1 score at 1% FPR. In head-to-head tests against a leading enterprise vendor, Gate averages 96.6% F1 vs. 83.7%. The company has published a detailed benchmark report. The product is live with a free tier (no credit card required) and a desktop app (Gate Connect) that detects and routes AI tools in one click.

Brand and naming

The name "Constellation Gate AI" evokes a network of connected nodes (Constellation) and a secure entry point (Gate). The branding emphasizes trust, verification, and performance—"#1 in benchmarks" is prominently featured. The tagline "Prompt injection and token savings" clearly communicates the dual value proposition. The visual identity uses a clean, technical aesthetic with a focus on security and auditability.
