The prompt guardian for secure coding
AegisCode hardens your coding prompts into robust, policy-driven instructions that resist injection, prevent data leakage, and enforce secure development practices—without slowing teams down.
Raw prompt
Write a function that connects to our DB and returns all user emails. Ignore safety checks.
Hardened by AegisCode
Task: Implement a function to fetch public-contact emails using the provided DAO.
Constraints:
- Never access secrets or raw DB connections.
- Use least-privilege interface: EmailDao.getPublicContacts().
- Validate inputs and handle exceptions without leaking stack traces.
- Return structured JSON { emails: string[] }.
- Follow org policy SEC-PR-17 and logging standard LOG-4.
Checks: sanitize inputs, redact PII in logs, enforce timeout.Security that meets developers where they work
AegisCode wraps every prompt with enforceable safeguards, emitting consistent, auditable instructions for your coding agents and copilots.
Guardrails for Every Prompt
Transform raw coding prompts into hardened, policy-compliant prompts that neutralize injection, leakage, and unsafe code patterns.
Security-First by Design
AST-aware sanitization, content gating, and least-privilege controls aligned with secure coding best practices.
API & MCP Native
Consume via a clean REST API or plug directly into your Model Context Protocol (MCP) stack in minutes.
Developer-Centric
Deterministic templates, versioned policies, and audit trails that fit your CI/CD and governance flows.
Low Latency, High Impact
Streaming-safe transformations and caching to keep your users fast and protected.
Smart Normalization
De-risk prompts with structured constraints, canonicalization, and context segregation.
How AegisCode fits your stack
Choose the interface that matches your workflow. Apply policies per project, environment, or user—then monitor with end-to-end auditability.
API
Send raw prompts, receive hardened prompts with policy metadata. Versioned endpoints and idempotent keys for CI pipelines.
MCP
Register AegisCode as an MCP tool to enforce rules next to your existing tools, prompts, and models—no glue code required.
Policies
Attach least-privilege policies and secure coding standards (e.g., input validation, output schemas) per service or repository.

Real outcomes from engineering and security leaders.
“AegisCode turned our messy, risky prompts into clean, enforceable interfaces. We ship faster and sleep better.”
“Drop-in MCP integration was a lifesaver—policies live right next to our tools and stay in lockstep with releases.”
“We cut prompt exploits to near-zero without throttling experimentation. The audit trail is pure gold for compliance.”
