Constellation Gate AI.

Constellation Gate AI

Constellation Gate AI is an enterprise-grade security gateway that sits between your AI agents and model APIs, blocking prompt injections, redacting sensitive data, and creating immutable audit trails before threats reach your models. It delivers 97.4% F1 performance across 16 public benchmarks while cutting token costs by 20% or more through intelligent compression and caching.

Product Highlights

• Inline Threat Detection: Scans every request and response in real-time for prompt injections, credential leaks, and PII exposure before they reach your models or return to users
• Immutable Audit Trail: Cryptographically chains every decision to a blockchain-backed record anchored to Constellation Digital Evidence, independently verifiable by auditors without trusting Gate
• Token Optimization: Applies lossless compression and prompt-cache injection to reduce outbound tokens by 20%+ and enable 2–10× cheaper cached prefix billing across any provider
• Drop-In Integration: Works as a proxy for existing SDKs with a single base_url change, or through Gate Connect desktop app that auto-detects and secures Claude Code, Cursor, Codex, and other agents in under a minute
• Policy Enforcement: Lets you write custom security rules that Gate enforces inline—blocking attacks, redacting secrets, flagging suspicious content, and sealing decisions to tamper-evident logs
• Multi-Provider Support: Secures calls to Anthropic, OpenAI, Google, xAI, OpenRouter, and hundreds of open-source models while letting you keep existing subscriptions or pay as you go through Gate

Use Cases

• AI Agent Security: Protect autonomous coding agents like Claude Code and Cursor from indirect injection attacks where compromised tool outputs hijack agent behavior and exfiltrate data
• Enterprise Compliance: Meet regulatory requirements for financial services and healthcare by ensuring every LLM interaction is logged to an immutable, third-party-verifiable audit trail
• Sensitive Data Handling: Automatically redact PII, API keys, and internal credentials from model responses before they reach end users or external systems
• Cost-Optimized AI Operations: Reduce inference spend by 20% or more through intelligent request compression and cross-provider prompt caching without changing model outputs or workflows

Target Audience

Constellation Gate AI serves security-conscious engineering teams and compliance-driven organizations running AI agents in production—particularly those in regulated industries who need provable security controls, immutable audit trails, and protection against OWASP LLM Top 10 threats without sacrificing development velocity or model choice.
