How does Constellation Gate AI protect against prompt injection?

It uses advanced detection mechanisms to identify and block prompt injection attempts in real-time, safeguarding AI agents from malicious inputs.

What is secret scanning and how does it work?

Secret scanning automatically detects and redacts sensitive data like API keys or passwords in AI agent interactions, preventing accidental exposure.

What are verifiable audit trails?

They are tamper-proof logs of all AI agent actions and decisions, enabling compliance and forensic analysis with cryptographic verification.

How does Constellation Gate AI achieve automatic token savings?

It optimizes token usage by filtering unnecessary inputs and outputs, reducing costs without compromising functionality.

Is Constellation Gate AI compatible with any AI agent framework?

Yes, it integrates seamlessly with popular AI agent frameworks and can be deployed as a middleware layer without code changes.

What is Constellation Gate AI?

Constellation Gate AI is a security and audit layer designed specifically for AI agents. It protects against prompt injection, scans for secrets and PII, and provides verifiable audit trails, all while automatically reducing token costs. Users deploy it to secure their AI interactions without changing their existing code or provider relationships.

Application scenarios

Prompt injection defense
Blocks attacker text that tries to override system prompts, exfiltrate data, or hijack conversations before the model sees it.
Secrets and PII redaction
Automatically redacts sensitive information like SSNs, API keys, or internal notes from model responses before they reach the user.
Indirect injection protection
Stops malicious instructions hidden in tool outputs (e.g., attacker-controlled webpages, tickets, or documents) from hijacking your agent.
Token cost optimization
Compresses outbound prompts losslessly to reduce token usage by 20% or more per request, and marks reusable prefixes for discounted cached billing.
Audit trail logging
Creates a verifiable record of every request and response for compliance and debugging.
Multi-provider model access
Provides a single endpoint to run frontier closed-source models (Claude, GPT, Gemini, Grok) and open-source models (Llama, Mistral, DeepSeek, Qwen) side by side.

Core Features

Prompt-injection blocking
Scans every incoming prompt and blocks malicious text before the model processes it, preventing data exfiltration and conversation hijacking.
Secret and PII redaction
Automatically detects and redacts credentials, PII, and other sensitive data from model responses before they are returned to the user.
Indirect injection prevention
Monitors tool outputs for attacker-controlled content and stops your agent from acting on malicious instructions.
Request compression
Applies lossless, cache-aware compression to outbound prompts, reducing token usage by 20% or more without altering the model's output.
Prompt-cache injection
Marks reusable prefixes (system prompts, tools, history) so providers bill them at discounted cached rates, achieving 2–10× savings on cached prefixes.
Gate Connect desktop app
Detects AI tools already installed on your machine and routes each through Gate with one click—most setups complete in under a minute.
One-line SDK integration
Developers can point their existing SDK at Gate's gateway by changing only the base URL, keeping the same code, provider key, and response shape.
Bring your own keys
Use your existing Anthropic, OpenAI, or other provider accounts; Gate adds security inspection, redaction, and audit trail on top without changing the model side.
Pay-as-you-go model access
Top up a balance with Gate to run any model from a single endpoint, without needing a provider account or contracts.

Target users

Security teams, AI engineers, and developers who build or deploy AI agents and need to protect against prompt injection, data leakage, and unauthorized tool calls. Also suitable for compliance officers and organizations that require verifiable audit trails for AI interactions.

How to use Constellation Gate AI?

For desktop users: Install the Gate Connect app, sign in once, and it automatically detects and routes your existing AI tools through Gate with one click per tool. For developers: Change one line in your code—point your existing SDK at https://gate.constellationgate.ai/v1 with your Gate API key—and all requests are scanned and audited. You can bring your own provider keys or top up a balance with Gate for pay-as-you-go access.

Pricing and free trial

Pricing is not explicitly listed on the provided website text. The site mentions "Pay as you go" and "Top up a balance with Gate," but no specific prices or free trial details are given.

Effect review

Constellation Gate AI addresses critical security gaps in AI agent workflows, particularly prompt injection and data leakage, which are top concerns for enterprise deployments. The combination of request compression and cache-aware billing offers a rare practical benefit: saving money while improving security. The one-line SDK integration and desktop app make adoption straightforward for both developers and non-technical users. However, the lack of transparent pricing on the site may be a barrier for teams evaluating the tool. Overall, it delivers a focused, well-designed security layer that fills a genuine need in the AI ecosystem.
