APISec Platform

Overview

APISec Platform is a runtime application-security service that maps API behavior and runs attacker-like tests against it. It is best suited to teams that need to validate complex access rules and investigate what a successful exploit could reach. For teams seeking that evidence, its broad discovery and replayable findings are compelling; endpoint-based pricing and deployment choices need careful consideration.

Key features

Rather than depending on documentation or developer interviews, APISec dynamically captures endpoints, parameters, authentication flows, roles, permissions, object ownership, and business logic. That can help teams work with APIs whose behavior is not fully documented. It is a broader approach than schema checks alone, so it may be more than a team needs if its priority is limited to validating API specifications.

Testing spans 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 a finding and judge its impact, rather than relying on an alert without a clear attack path.

APISec can discover APIs across infrastructure, source, gateways, ingress and authentication paths, web apps, Postman, SwaggerHub, Insomnia, and CI/CD. Its discovery also covers agents, MCP servers, and LLM call sites; supported API formats include OpenAPI Specification, Swagger, Postman, and RAML. Nearly every aspect of the platform is exposed through an API for custom automations and integrations, a useful fit for teams that want to connect testing to existing workflows.

Public APIs run against APISec’s public cloud. Private and on-premises APIs can use an APISec Kubernetes or Docker container, while cloud deployments can run in the customer’s GCP, Azure, or AWS environment. Hosted agents can also validate private APIs. The deployment range is a strength for teams with different hosting needs, but private and on-premises testing carries custom pricing.

The free, open-source APISec Surface discovery tool runs locally and states that nothing leaves the machine. Surface includes local discovery tools, GitHub Actions, and a browser extension; AI Surface and MCP audit use MIT licenses, and the Bolt Browser Extension uses Apache 2.0. These tools offer a distinct, locally run discovery option, but do not replace the platform’s paid continuous validation plans.

Pricing

APISec uses a freemium model, with paid plans priced per 100 endpoints in increments. That makes the endpoint count central to budgeting as coverage grows. The published monthly prices are per 100 endpoints; annual equivalents are also provided for the Standard and Pro plans.

Free is a way to explore basic simulations against public APIs, not a substitute for continuous validation. Standard is the entry point for teams that want ongoing testing and business-logic coverage; its per-100-endpoint price makes it important to size the scope before choosing it. Pro suits teams that need the added integrations, custom simulations, reporting, and SLA support. Bug Bounty is aimed at periodic expert review rather than continuous testing. Private and on-premises API testing uses custom pricing, so the Standard and Pro prices do not establish those deployment costs. APISec offers a free trial, but no trial length is stated.

Platforms

APISec supports API, extension, Linux, self-hosted, and web environments. Public APIs use APISec’s cloud, while private and on-premises options include customer-environment cloud deployments and Kubernetes or Docker containers. This range accommodates teams that cannot send private API testing through a public-cloud deployment, though they should account for custom pricing.

Who it's for

APISec is a strong fit for security and engineering teams responsible for APIs with complex permissions, business logic, or private deployment requirements. Its application model and exploit evidence are especially relevant when teams need to understand the path and reach of an attack. It is less suited to buyers who only need schema-driven tests or who want to budget without accounting for endpoint-based increments.

Pros and cons

Pros

• Findings include attack evidence. Request sequence, reached data, blast radius, replay, and a suggested resolution help teams assess and reproduce validated exploits.
• Discovery spans varied sources. Coverage across infrastructure, gateways, web apps, development tools, CI/CD, agents, and LLM call sites can help teams map APIs across different parts of their environment.
• Multiple deployment paths. Public cloud, customer-cloud, Kubernetes, and Docker options give teams choices for public, private, and on-premises API testing.
• A local discovery tool is available. APISec Surface runs in the user’s environment and states that nothing leaves the machine.

Cons

• Paid pricing scales in endpoint increments. Standard and Pro are priced per 100 endpoints, so the listed entry prices are not a universal total for larger API estates.
• Private and on-premises testing requires custom pricing. Buyers cannot use the published Standard or Pro figures to determine the cost of those deployments.
• Free testing is limited to public APIs and basic simulations. Teams seeking ongoing automated validation and business-logic attacks need a paid plan.

Alternatives

Consider 42Crunch API Security Platform if you want a free plan centered on an AI coding plugin, OpenAPI audit, vulnerability scans, and automatic fixes. Pynt is worth considering if you want a free starter plan capped at 10 API endpoints, with a business plan also available.

Schemathesis is an open-source option that generates tests from OpenAPI and GraphQL schemas. VulnAPI is a free MIT-licensed option for educational and testing purposes. AquilaX API Security Scanner may suit teams prioritizing secrets scanning, PII detection, compliance auditing, unlimited scans, and CI/CD and IDE integrations on its free plan.

Beagle Security offers a free plan with one lite test per month, monthly surface scan reports, and SSL and domain expiry monitoring. ZeroThreat starts with five free scan credits valid for 15 days, followed by one scan credit per month and one target per account. Bright Security DAST is another option.

Verdict

Choose APISec Platform if your team needs continuous, evidence-backed testing of APIs with complex access rules, and can plan around per-endpoint pricing and its deployment requirements. Its strongest reason to buy is the combination of broad application discovery and validated, replayable exploit evidence. Look elsewhere if you need only schema-based testing or require a predictable published price for private or on-premises coverage.
