About

Formal is a protocol-aware reverse proxy that secures access to databases, APIs, infrastructure, and AI tools by enforcing least privilege at the wire-protocol level. Deployed as a single stateless binary in a VPC through Terraform, Kubernetes, or Docker, it sits between identities and resources without application changes, SDKs, or agents. Formal parses more than 15 protocols, including PostgreSQL, MySQL, MongoDB, Snowflake, SSH, Kubernetes, HTTP, MCP, S3, Redis, RDP, BigQuery, ClickHouse, and DynamoDB, allowing query-level decisions instead of generic network filtering. Policies can authenticate and authorize users, mask or filter fields, rewrite requests, block actions, require MFA, quarantine sessions, suspend access, or support impersonation across session, request, and response stages. Teams can secure AI agents and MCP servers by stripping PII before it reaches a model, blocking unauthorized tool calls, and auditing every action.

About

Vulnify is a runtime authorization service for developers and security teams building AI agents that use tools or APIs. Before a tool runs, the agent sends action metadata—including the agent, action, resource, destination, and record count—and receives an ALLOW, REVIEW, or BLOCK decision with a 0–100 risk score and reasons. Teams can define and test YAML policies through a command-line interface, and add checks using Node.js or Python SDKs, a REST API, or adapters for agent frameworks. Monitor mode records decisions without blocking actions. Fail-closed behavior blocks actions if Vulnify is unavailable unless fail-open is configured. A hash-chained audit log records decisions, and paid plans include human review workflows. Common use cases include governing data exports, external messages, payments, and other agent-initiated actions. Vulnify evaluates action metadata rather than the contents of affected records.
