Secure the

Future of AI

A decentralized security layer built to defend AI agents, swarms, users, and code in real time. SIGIL AI scans, learns, codes, fixes, and deploys secure systems - automatically, at scale. Security isn’t an add-on anymore. It’s the foundation.

Protect Every Agent.
Every Action. Every Line of Code.
Security isn’t optional, it’s the backbone of autonomous systems.

Model Context Protocol (MCP)
Autonomous code defense. Zero config.

Sigil AI's MCP learns your codebase – even millions of lines – detecting vulnerabilities, bad logic, and unsafe dependencies.
It then fixes the code and deploys a secure version – automatically, in real time.
Zero configuration. No human in the loop. Just autonomous protection that scales.

Securing Autonomous Intelligence
Live defense for fast-moving agents.

Autonomous agents act fast — writing, deploying, executing.
SIGIL AI ensures every step they take is secure.
From API access to runtime behavior, our infrastructure monitors agent activity and locks down threats as they emerge.
Autonomy needs defense. SIGIL delivers it.

SIGIL AI’s MCP Demo

Watch SIGIL’s MCP in Action

The MCP is powered by an LLM trained on millions of lines of code, vulnerabilities, and real-world exploits. It detects structural flaws, unsafe logic, backdoors, and bad APIs — then auto-fixes the code, tests and redeploys a secure version in real time. No setup. No waiting. Just live protection with a zero configuration policy.

Made to Work Where You Build

SIGIL AI is integration-ready across the tools, clouds, and frameworks you rely on.

With built in support for Cursor, Windsurf, OpenAI Codex, Cline and more!

MCP Server

SIGIL’s real-time security core. Scans code, detects threats, fixes them, and redeploys – fully autonomous, no manual review required.

Security Bot

A lightweight watchdog for chat-based workflows. It flags unsafe patterns, bad commits, and risky changes as they happen.

Security API

Automate threat detection and patching with direct API access. Scan, validate, fix, and deploy via your own pipelines.

Developer SDK

Secure any agent, backend, or tool in minutes. Drop-in SDKs for JS, Python, and shell scripts.

Your AI Security Copilot

The SIGIL Terminal is your real-time security assistant.
Ask it questions. Scan files. Validate URLs, repositories, or libraries.
It analyzes every input using SIGIL’s fine-tuned LLMs and integrated threat engines — giving you instant feedback as you build.
