Best API Security Software

OpenRouter is a unified interface for large language models that gives developers and teams one API to access hundreds of models from 70+ providers. Built for AI app builders, startups, and enterprises, it simplifies model experimentation, routing, and deployment by letting you use an OpenAI-compatible SDK while switching between providers like OpenAI, Anthropic, Google, Meta, Mistral, and more. Its biggest value is flexibility: you can optimize for price, speed, uptime, or policy requirements without rewriting your integration for every vendor. OpenRouter also supports distributed routing with fallback options, helping maintain higher availability when a provider is slow or unavailable. With custom data policies, transparent usage-based pricing, and no subscription requirement, it is especially useful for teams that want to control costs and reduce operational overhead while building production-grade AI products, agents, and internal tools.

APIsec is an AI-powered platform for continuous, automated API penetration testing. It ships more than 1,200 pre-built security playbooks covering the OWASP API Security Top 10 and generates thousands of attack variations per endpoint without requiring manual scripting, catching business logic, role-configuration, and access-control flaws such as BOLA.

The platform integrates into CI/CD pipelines so every commit triggers a full test run, with continuous retesting once issues are fixed. Plans range from a free tier for public API testing to Standard and Pro tiers priced per 100 endpoints, plus a custom-priced certified penetration test option. Customers include Nike, FedEx, PayPal, and Bank of America.

Invicti is an Austin, Texas-based application security company, formed from the merger of Netsparker and Acunetix, that extends its proof-based dynamic application security testing (DAST) engine to API security. It discovers documented, shadow, and zombie APIs through multiple methods, including OpenAPI, Swagger, and gRPC proto file imports, source code scanning, and encrypted traffic analysis via eBPF, then scans REST, SOAP, and GraphQL APIs with stateful, context-aware tests.

Invicti validates vulnerabilities with proof-of-exploit before reporting them, which the company states delivers 99.98 percent scanning accuracy. Plans are packaged as Web & API, AppSec Core, and Enterprise DAST, alongside an ASPM offering that unifies DAST, SAST, SCA, and API security findings. Invicti does not publish self-service pricing; cost is quoted based on the number of applications, domains, or API targets you need to scan.

Akto is a San Francisco-based API security platform, also available as an open source project, that covers discovery, security testing, posture management, and runtime protection across the API lifecycle. It ships with a library of more than 1,000 pre-built tests covering the OWASP API Top 10 and HackerOne Top 10 categories, including BOLA, authentication, and SSRF issues, and can start generating an API inventory within about 60 seconds of setup.

Akto has expanded beyond traditional API testing into agentic AI security, offering Shadow AI discovery, AI governance and audit trails, and real-time guardrails for tools like Claude and ChatGPT. The company offers a free, self-hosted open source edition on GitHub alongside usage-based, enterprise-grade cloud pricing that is quoted after contacting sales; no fixed dollar pricing is published on its official pricing page.

Bright Security, formerly NeuraLegion, is a Tel Aviv-based dynamic application security testing platform built for developers. It scans web apps, REST, GraphQL, SOAP, and gRPC APIs, and GenAI or LLM-based applications, running attacks mapped to the OWASP Top 10, API Top 10, and LLM Top 10. Bright uses AI-driven runtime validation to confirm a flaw is genuinely exploitable before reporting it, which the company says keeps false positives under 3 percent.

The platform accepts crawler-based, HAR file, and OpenAPI or Swagger scan targets, and integrates with more than a dozen CI/CD platforms for Git-aware, pull-request-level testing. Bright also offers automated remediation with AI-generated fixes and a validation loop that confirms the fixes work. Pricing is not published; Bright sells through a tailored quote based on application scope, testing depth, and deployment needs.

Pynt is a Tel Aviv-based API security testing platform that discovers and tests APIs, LLMs, and MCP tools in one product. Unlike traffic-fuzzing scanners, Pynt is context-aware: it learns an application's real API structure, sessions, and parameters from live traffic and testing tool logs, then simulates realistic attacks such as broken authorization, business logic abuse, and sensitive data exposure. It covers the OWASP API, Web, and LLM Top 10 risk lists and integrates directly into Postman, Burp Suite, and Selenium.

Built for developer-first workflows, Pynt runs automated tests in CI/CD pipelines in minutes and produces automated penetration test reports. It is used by more than 2,000 organizations and offers a free tier for running API checks through its native integrations, alongside paid Business and Enterprise plans with custom pricing, SSO, and optional self-hosted deployment for larger teams.

Cequence Security offers a unified application and API protection platform that discovers, tests, and defends APIs across cloud, hybrid, and on premises environments. It continuously inventories internal, external, and third-party APIs, flags shadow endpoints, and maps risks to more than 25 compliance frameworks including OWASP API Top 10, PCI DSS, GDPR, and HIPAA.

Unlike alert-only tools, Cequence blocks attacks inline, covering account takeover, credential stuffing, fake account creation, scraping, and business logic abuse. It also includes API security testing for CI/CD pipelines, an AI Gateway for securing agentic and LLM traffic, and a conversational AI assistant for investigating findings. Pricing is custom and available only by contacting sales.

Imperva API Security is a module within Imperva's application security platform that discovers, assesses, and protects APIs across cloud, on premises, and hybrid environments. It continuously finds public, private, and shadow APIs, then evaluates them against the OWASP API Security Top 10 to surface design flaws and misconfigurations before attackers can exploit them.

The platform uses machine learning to detect and respond to Broken Object Level Authorization exploits and other business logic abuse in real time. It also offers specification-based testing and fuzzing to catch flaws before production, and integrates natively with Imperva's Advanced Bot Protection, WAF, and DDoS defenses, plus gateways like Kong, MuleSoft, Azure APIM, and Apigee. Pricing is quote-based through Imperva sales.

Akamai API Security, formerly Noname Security, is a platform-agnostic solution that discovers, tests, detects and responds to API threats across hybrid, SaaS and on-premises environments. It automatically inventories shadow, zombie and AI-related APIs, covers the OWASP API Security Top 10, runs over 200 dynamic tests to simulate malicious traffic before production, and integrates with WAFs, SIEMs and ITSM tools for automated remediation workflows. The platform does not require Akamai's CDN and works across multiple third-party CDNs, WAFs and gateways.

Akamai completed its acquisition of Noname Security in June 2024 for approximately 450 million dollars, and the product now operates under the Akamai brand. Pricing is not publicly published; Akamai uses a consumption-based enterprise model priced on API call volume, number of monitored environments and optional managed SOC services, quoted through direct sales.

Wallarm is an API and AI security platform that discovers, tests, and protects APIs and web applications across cloud, hybrid, and on premises environments. It combines a cloud native WAAP with dedicated API security tools to block OWASP API Top 10 threats, automatic BOLA attacks, credential stuffing, and bot abuse in real time across REST, GraphQL, gRPC, SOAP, and WebSocket traffic.

The platform includes API Attack Surface Management for discovering shadow and zombie APIs, schema based security testing, and threat replay testing to validate fixes. Wallarm integrates with existing API gateways, proxies, and CI/CD pipelines, and offers a free Security Edge tier alongside paid WAAP and Advanced API Security subscriptions priced on request.
