Tools being compared often don't even solve the same problem. Before comparing prices and features, it pays to look at the category:

  • AI-driven testing and pentesting: AI agents actively attack the API, also across multiple identities and steps (Venedy, Equixly, Escape).
  • DAST / API testing: running APIs are actively tested for vulnerabilities, before or with every deployment (StackHawk, ZAP, Akto).
  • Runtime protection: live traffic is analyzed and attacks are detected or blocked in operation (Salt, Wallarm, Akamai).
  • Contract/design-first: the API specification (OpenAPI) is checked for conformance and errors, complemented by scans (42Crunch).

How "real" is BOLA testing?

BOLA (Broken Object Level Authorization) means: user A reaches user B's objects. To find this, a tool has to understand which objects belong to whom and then deliberately request foreign ones. There are two ways:

Template- and role-based (e.g. Akto, StackHawk): Test roles and tokens are set up in advance, and the tool runs prebuilt test patterns with them. BOLA is found within the configured scope, but setup work is required, and anything that fits no template can be missed.

Agent-based (e.g. Venedy, Equixly): Test users and context are created by the AI agents themselves. From the API's behaviour it is inferred which objects belong to whom, and attack paths are tried out without anyone writing a template first.

Both ways are legitimate. The difference lies in the setup effort and in how well multi-step, atypical logic flaws are found.

An example that shows the difference: With an ordering API, authorization is checked cleanly on every single call. Only by combining two endpoints, for instance creating an invoice via its ID and then retrieving it through a second, less strictly checked endpoint, does foreign data become accessible. No single request looks wrong, which is why a purely template-based test usually does not trigger.

The tools in brief

Venedy - AI agent testing focused on logic flaws. The agents create test users and context themselves and derive attack paths from the API's behavior, without predefined templates. Four agents debate every contested finding, a deterministic engine decides, and every finding is documented with its log, HTTP evidence and DORA/NIS2 mapping. Operated conversationally, with intervention at every step. Hosting exclusively in German data centers (STACKIT), AI via European-hosted open-weight models, no training on customer data. Venedy is operated as a platform, no installation of your own is needed. Currently in the pilot program: pilot customers shape the roadmap and get preferential terms. Entry from around €625 per month.

Equixly - AI agent for continuous API pentests from Florence. Tests with multiple identities ("create as one, attack as another") and backs findings with request and response. According to the vendor, data stays in the EU and the AI model runs in-house. €4,999 per pentest, the platform on request.

Salt Security - Enterprise runtime protection, strong at detecting and blocking attacks in live traffic. Available as SaaS, on-premises or hybrid. No public prices.

42Crunch - Contract-first specialist: the OpenAPI specification is checked against the OWASP API Top 10, complemented by a conformance scan that in version 2 also tests BOLA and BFLA with two credentials. Strong in shift-left. Cloud, on-premises or hybrid.

Akamai API Security - Part of Akamai since the acquisition of Noname Security in 2024. Combines discovery, posture management, runtime protection and tests in CI/CD. Prices on request.

Wallarm - Runtime protection for APIs with complementary API testing. Runs in the cloud (US or EU), hybrid or at the edge.

Escape - AI-driven offensive security and DAST platform from Paris, with an agent for internal applications in the customer network.

StackHawk - Solid DAST for development teams. "Business Logic Testing" tests BOLA and BFLA across roles, which requires an OpenAPI specification and at least two test accounts. Affordable entry.

Akto - Open-source-oriented platform: the community edition (MIT) offers API discovery, a test framework with 1000+ tests and CI/CD integration, self-hostable. BOLA checks are template- and role-based. With self-hosting, setup and operation are up to the user.

OWASP ZAP - The free open-source classic. Good for getting started and pattern-based scans. Business logic flaws require manual configuration.

What to look for when choosing

  • Deployment & data residency: SaaS or self-hosted? Is EU hosting required for compliance (DORA, NIS2, GDPR)?
  • CI/CD integration: Does the test run automatically on every deployment, or only manually?
  • Setup effort: Do test roles, tokens and seed data have to be maintained by hand, or does the tool handle that?
  • Control & intervention: Is it operated through dashboards and config files, or conversationally through an agent that can be stepped into at any point?
  • Logic depth: Just pattern scanning, or real BOLA/BFLA testing across multiple endpoints?
  • False positives: How much rework does each run create?
  • Traceability: Does the tool explain why a finding is a finding, or is it a black box?
  • Data location & AI provider: where are data and findings stored, where does the AI model run, and is customer data used for training?

Which tool for which case?

  • Continuous AI logic testing with hosting in Germany, traceable findings and DORA/NIS2 mapping, from around €625 per month → Venedy
  • AI pentest at a fixed price per test → Equixly
  • Monitor live traffic in operation → Salt, Wallarm or Akamai
  • Self-hosting or open source → Akto
  • Affordable DAST in CI → StackHawk or ZAP
  • Secure the OpenAPI specification → 42Crunch

Frequently asked questions

What is the best API security tool?

There isn't one. The choice depends on whether you want to test before production (DAST, AI testing) or protect in operation (runtime).

Are there open-source API security tools?

Yes, OWASP ZAP and Akto (Community Edition) are open source.

Which tool finds business logic flaws such as BOLA?

Venedy and Equixly test them actively with agents, StackHawk, 42Crunch (Scan v2) and Akto with configured roles or credentials. Salt detects such attacks at runtime. Pure pattern scanners do not.

Which API security tools host in the EU?

Venedy hosts exclusively in German data centers (STACKIT), Equixly keeps data in the EU according to its own statement, Wallarm offers an EU cloud. For the other vendors, an EU data location is not publicly stated or only possible via self-hosting.
