About Symbiotic Security

Symbiotic Security's main product, Symbiotic Code, is a harness that runs an AI coding agent inside security controls.

Pre-generation hooks apply the organization's policies, post-generation checks scan the output, and any vulnerability found is fixed by an agent and revalidated for functionality before the code reaches the developer.

It is model agnostic, supporting Claude, OpenAI, Mistral, Gemini, DeepSeek and bring-your-own models, and existing agent skills and MCP servers carry over. The company also offers IDE plugins for VS Code, Cursor and Kiro and a CI policy gate.

It can run in Symbiotic's cloud, the customer's cloud or on premises, with detection running client side and a privacy mode that stores no code.
