APISec Platform vs apPosture API Security

APISec Platform is an application security tool for validating exploits against APIs and applications. It discovers applications, builds a dynamic model of their behavior, and runs attacker-like tests at runtime. The model can capture endpoints, parameters, authentication flows, roles, permissions, object ownership, and business logic without documentation or developer interviews. Tests cover business logic, data access, permissions, configuration, infrastructure, and controls such as injection and token handling. For validated exploits, the platform returns the request sequence, data reached, blast radius, replay, and a suggested resolution. APISec says it can find APIs across infrastructure, source, gateways, ingress and authentication paths, web apps, development tools, and CI/CD, as well as agents, MCP servers, and LLM call sites. Public APIs run against its cloud; private and on-premises APIs can use a Kubernetes or Docker container, while cloud deployments can run in a customer’s GCP, Azure, or AWS environment. The free plan covers public API testing and basic simulations. Standard costs $690 a month per 100 endpoints; Pro costs $2,750 a month per 100 endpoints.

apPosture API Security inventories API endpoints, assigns risk priorities, and compares declared API contracts with running APIs. Its risk verdict combines whether an endpoint is public, handles sensitive data, and lacks provable authentication. Endpoint labels distinguish code-and-runtime provenance, source-only findings, and runtime-only observations. Discovery uses SAST attack-maps, DAST crawling, an attached OpenAPI specification, and external subdomain probing; listed coverage includes OpenAPI import, GraphQL, gRPC, HTTP/2, h2c, and REST. Teams can diff an OpenAPI specification against running endpoints to identify documented, shadow, declared-untested, and auth-drift states. Runtime correlation ingests existing access logs out of band rather than inline in the request path. The product supports API-scoped compliance across seven frameworks and SARIF export. It can run self-hosted, in a customer's cloud, or as a dedicated managed instance; self-hosted deployment uses a local LLM and needs no outbound connections after setup. The listed Essentials plan is $35 a year, billed at $35 / dev · mo annually, with a $2,000 / year minimum; API Security is an additional $15 / dev · mo. Platform is $70 a year, billed at $70 / dev · mo annually, with a $4,000 / year minimum. Enterprise is $90 a year, billed at $90 / dev · mo annually, with a $7,500 / year minimum. There is no free tier; each edition starts with the same 30-day proof of concept.
