APISec Platform

Overview

APISec Platform is an API security service that discovers applications, builds a live model of their behavior, and validates attacks at runtime. It is best suited to teams securing APIs with complex permissions or business rules. Its strongest draw is evidence-backed exploit validation, though per-endpoint costs and deployment requirements deserve careful consideration.

Key features

APISec builds a dynamic map of endpoints, parameters, authentication flows, roles, permissions, object ownership, and business logic without relying on documentation or developer interviews. That can help teams investigate APIs whose specifications are incomplete, but buyers seeking only schema checks may find this broader runtime approach unnecessary.

Its tests cover business logic, data access, authorization, configuration, infrastructure, and controls including injection and token handling. Findings include the request sequence, data reached, potential blast radius, replay, and a suggested resolution. That context gives engineers a practical way to reproduce and assess a problem rather than treating every alert as equally actionable.

Discovery can draw from infrastructure, source, gateways, ingress and authentication paths, web apps, Postman, SwaggerHub, Insomnia, and CI/CD, as well as agents, MCP servers, and LLM call sites. Supported API formats include OpenAPI Specification, Swagger, Postman, and RAML. Nearly every aspect of the product is exposed through an API, which suits teams building custom automation.

Public APIs run through APISec’s 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. Hosted agents can also validate private APIs. This range supports varied infrastructure, but the right setup depends on where the APIs live and the deployment model the team can operate.

The open-source APISec Surface discovery tool runs locally and says it sends nothing off the user’s machine. Its package includes local discovery tools, GitHub Actions, and a browser extension; AI Surface and MCP audit use MIT licenses, while the Bolt Browser Extension uses Apache 2.0.

Pricing

The Free plan costs nothing, billed $0 forever, requires no credit card, and includes public API testing, basic test simulations, community support, and dashboard access. It is a low-commitment way to explore the product, but it does not include the continuous validation and business-logic attacks named in Standard.

Standard costs $690 a month, billed $690/mo per 100 endpoints or $8,275/yr. It adds continuous automated validation, business-logic attacks such as BOLA and RBAC, team collaboration, and dedicated support. This is the entry paid option for teams that need ongoing API testing; its per-100-endpoint increments make the endpoint count central to budgeting.

Pro costs $2,750 a month, billed $2,750/mo per 100 endpoints or $33,075/yr. It includes Standard plus full CI/CD and ticketing integrations, custom attack simulations, advanced reporting and SLAs, white-glove onboarding, and premium support. It fits teams that need those integrations and service commitments, but is a substantial step up from Standard.

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. On-premises and private API testing also use custom pricing. A free trial is offered; the Free plan itself is billed at $0 forever.

Platforms

APISec supports API, extension, Linux, self-hosted, and web environments. Its public-cloud and customer-cloud deployment choices make it relevant to teams with mixed infrastructure, while self-hosting is an option for private or on-premises APIs.

Who it's for

APISec is a strong fit for security and engineering teams that need to discover APIs across multiple sources, test authorization and business logic, and reproduce validated exploits. It is less compelling for teams that only need lightweight schema-driven testing or cannot justify endpoint-based paid pricing.

Pros and cons

• Pros: Dynamic modeling covers roles, ownership, and business logic without depending on documentation, useful for complex or poorly documented APIs.
• Pros: Validated exploits include replayable requests and impact context, helping teams prioritize and investigate findings.
• Pros: Local discovery and customer-cloud or container deployment options support different privacy and infrastructure needs.
• Cons: Paid plans are priced per 100 endpoints, so costs scale with the API footprint.
• Cons: Private and on-premises testing can require custom pricing, complicating cost planning.
• Cons: The Free plan is limited to public API testing and basic simulations, so it is not a substitute for continuous paid validation.

Verdict

Choose APISec if your team needs broad API discovery and reproducible validation of business-logic and authorization flaws, especially across complex or private environments. The detailed exploit evidence is its clearest advantage; teams with smaller endpoint footprints, schema-only needs, or tight budgets should compare simpler or free options first.
