APISec Platform

APISec Platform is an application security tool that discovers APIs and applications, builds a dynamic model of their behavior, and runs attacker-like tests at runtime. Its model can capture endpoints, parameters, authentication flows, roles, permissions, object ownership, and business logic without relying on documentation or developer interviews. Tests cover business logic, data access, permissions, configuration, infrastructure, and controls such as injection and token handling. When it validates an exploit, APISec returns the request sequence, data reached, blast radius, replay, and a suggested resolution. It says it can discover APIs across infrastructure, source, gateways, web apps, documentation tools, and CI/CD, as well as agents, MCP servers, and LLM call sites. Public APIs run against APISec’s cloud; private and on-premises APIs can use Kubernetes or Docker containers, and cloud deployments can run in a customer’s GCP, Azure, or AWS environment. Plans include free public API testing and basic simulations; Standard costs $690/mo per 100 endpoints.

APISec Platform combines API discovery, dynamic application modeling, and runtime exploit validation. Its free plan is narrow, while paid pricing scales by endpoint count.

It suits teams that need runtime validation of API and application security, including testing business logic and permissions. Teams with private or on-premises APIs can use container deployment options.

Overview

APISec Platform is a runtime security-validation platform for teams responsible for APIs whose behavior and access rules need more than a specification check. Its central advantage is connecting broad discovery with tests that show what an exploit can reach; endpoint-based pricing makes scope an important part of the buying decision.

Key features

APISec builds a live application model covering endpoints, parameters, authentication flows, roles, permissions, object ownership, and business logic, without requiring documentation or developer interviews. That makes it relevant when API behavior is not fully captured in specifications. Teams that only need checks against a defined API schema may not need this wider modeling approach.

Testing reaches business logic, data access, roles and permissions, configuration, infrastructure, and controls such as injection and token handling. A validated exploit comes with its request sequence, the data it reached, its blast radius, replay, and a suggested resolution. That evidence can help security and engineering teams reproduce and prioritize issues rather than treating every finding as an abstract warning.

Discovery can draw on infrastructure, source, gateways, ingress and authentication paths, web apps, Postman, SwaggerHub, Insomnia, and CI/CD, including agents, MCP servers, and LLM call sites. Supported API formats include OpenAPI Specification, Swagger, Postman, and RAML. The platform also exposes nearly every aspect through an API, a useful basis for custom automation and integrations.

Public APIs run against APISec’s public cloud. Private and on-premises APIs can be tested with an APISec Kubernetes or Docker container, while cloud deployments can run in a customer’s GCP, Azure, or AWS environment. Hosted agents can also validate private APIs. These options give teams different deployment paths, but private and on-premises testing may require custom pricing.

The free, open-source APISec Surface discovery tool runs locally and says nothing leaves the machine. Its tools include local discovery, GitHub Actions, and a browser extension; AI Surface and MCP audit are listed under MIT licenses, and the Bolt Browser Extension under Apache 2.0. This is a distinct privacy-conscious discovery option, not a substitute for the paid platform’s broader validation plans.

Pricing

APISec uses freemium pricing, with paid plans priced per 100 endpoints in increments. Free is free, billed $0 forever, requires no credit card, and includes public API testing, basic test simulations, dashboard access, and community support. It is a low-commitment way to explore the product, but its public-API scope and basic simulations make it a limited fit for teams needing continuous validation or private API coverage.

Standard costs $690 a month, billed $690/mo per 100 endpoints or $8,275/yr. It adds continuous automated validation, business-logic attacks including BOLA and RBAC, continuous API testing, team collaboration, and dedicated support. This is the entry point for teams ready to run ongoing tests; the endpoint increments mean the quoted starting price should not be treated as a flat price for any portfolio size.

Pro costs $2,750 a month, billed $2,750/mo per 100 endpoints or $33,075/yr. It includes everything in Standard, plus full CI/CD and ticketing integrations, custom attack simulations, advanced reporting and SLAs, white-glove onboarding, and premium support. The higher tier is for teams that need those integrations and service commitments; smaller teams that can work without them may find Standard sufficient.

Bug Bounty has custom pricing and offers certified expert reports, manual and ad-hoc deep dives, private and public API testing, and authentication support for periodic assurance. Custom pricing also applies to on-premises and private API testing. The free tier has community support, compared with dedicated support for Standard and premium support for Pro.

Platforms

APISec supports API, extension, Linux, self-hosted, and web platforms. Its deployment choices include APISec’s public cloud for public APIs, customer-environment cloud deployments on GCP, Azure, or AWS, and Kubernetes or Docker containers for private and on-premises APIs.

Who it's for

APISec is best suited to organizations that need to discover APIs across multiple sources and validate authorization, authentication, input handling, and business logic at runtime. Standard fits teams seeking continuous testing and collaboration; Pro is aimed at teams requiring CI/CD and ticketing integrations, custom simulations, reporting, SLAs, and premium support. The free plan suits initial exploration of public API testing. Teams seeking only lightweight schema checks, or those unable to justify endpoint-based costs, should look elsewhere.

Pros and cons

• Pro: Dynamic modeling includes roles, object ownership, and business logic, helping expose access problems that a simple inventory would not explain.
• Pro: Exploit reports include replay and reached-data context, giving teams evidence to investigate and resolve findings.
• Pro: Discovery spans infrastructure, development tools, gateways, CI/CD, and emerging agent and LLM call sites.
• Con: Standard and Pro are priced per 100 endpoints, so costs scale with API scope rather than staying at the entry price.
• Con: Free covers public APIs and basic simulations, while private and on-premises testing can require custom pricing.

Verdict

Choose APISec Platform if your team needs broad API discovery, dynamic modeling of access and business rules, and replayable proof of runtime exploits. The validated evidence is its strongest reason to buy; the per-100-endpoint pricing and custom costs for private or on-premises testing are the main reasons to compare alternatives before scaling up.
