A secure-by-default AI coding harness that enforces security policy before code is written

Symbiotic Security makes Symbiotic Code, a secure-by-default harness for AI coding. Rather than scanning AI-generated code after the fact, it runs frontier models such as Claude and GPT inside a loop that applies the organization’s security policies before code is generated, detects and automatically fixes vulnerabilities as the code is written, and verifies the result before it is returned to the developer.

The harness also governs the coding agent itself. Every MCP server, skill, and plugin the agent uses is logged and subject to policy, and sandboxing and prompt protection guard against data leaks and attempts to hijack the agent. Model routing picks the model turn by turn to keep AI costs down.

Symbiotic works across the IDE, pull requests, and CI, so the same policies apply wherever code is written or reviewed. It can run in Symbiotic’s cloud, in the customer’s own cloud, or on-premises.
