Secure, govern, and optimize every AI prompt — before it reaches a model.
Margah sits between your application and GenAI providers to prevent prompt injection, stop data leaks, enforce output contracts, and keep token spend under control.
No credit card required. Redacted logs by default. BYOK supported.

Your prompts are the attack surface.
Users, documents, and integrations can all inject instructions that bypass safeguards or attempt data exfiltration. Margah detects and blocks unsafe requests deterministically.
Compliance without slowing developers.
Margah stores audit events redacted by default and groups repeated violations into incidents. Security teams get visibility; developers keep shipping.
Why Margah Gateway?
As enterprises rush to integrate AI into their workflows, a critical gap has emerged: the prompts flowing between users and AI models often contain sensitive data, proprietary information, and potential security vulnerabilities that traditional security tools simply weren't designed to catch. Margah Gateway sits at this critical junction, providing real-time governance and security for every AI interaction before it leaves your infrastructure. Whether it's detecting prompt injection attacks that could manipulate your AI systems, redacting PII and secrets before they reach third-party APIs, or enforcing compliance policies across your entire organization, Margah ensures you can embrace AI innovation without exposing your business to unacceptable risk. It's not about slowing down AI adoption—it's about making it safe enough to accelerate.
Features mapped to buyer pain
Margah is a drop-in gateway that turns GenAI from a risk surface into a controlled system. Each capability directly resolves a real production pain.
Validate prompts & context before execution
Detect direct and indirect injection, exfiltration attempts, and obfuscation.
- Direct injection detection
- Indirect injection detection (context-aware)
- Exfiltration attempt detection
- Obfuscation / homoglyph checks
- Multi-turn attack detection
Default-on redaction that preserves meaning
Automatically redact PII and secrets across input, context, output, and stored events.
- PII: email, phone, SSN (US), credit card
- Secrets: API keys, JWTs, AWS keys, connection strings
- Modes: mask, remove, placeholder
- Custom redaction patterns
- Logs stored redacted by default
Execute with output contracts & validation
Enforce JSON schema outputs and safely retry on schema failure.
- Output contract injection (internal step)
- JSON Schema enforcement (optional)
- Configurable retries on schema failure
- Streaming responses with SSE
- Post-output policy checks + redaction
How Margah works
You keep your architecture and prompts. Margah adds a security and governance layer with deterministic processing and redacted-by-default audit events.
