Levo is a developer-aligned API security testing platform that uses eBPF technology to discover and document your APIs without requiring code changes. It provides you with a privacy-preserving architecture that ensures no sensitive data leaves your environment while it monitors for misconfigurations and vulnerabilities. You can automate offensive security testing in your CI/CD pipeline, focusing on critical issues like business logic abuse and data leaks to keep your engineering velocity high.

In addition, the platform builds an up-to-date API catalog and documentation automatically, helping you eliminate shadow and zombie APIs. Its sensors are designed to be lightweight, resulting in minimal resource overhead even in high-traffic environments. This makes it an excellent choice for teams that want to shift security left and gain real-time visibility into their API risk posture without introducing friction or excessive cloud costs into their daily workflows.

Escape is a modern DAST platform that specializes in securing GraphQL and REST APIs by testing their business logic rather than just checking for missing headers. It uses a proprietary AI-powered algorithm to autonomously discover your attack surface and run over 100 security tests, including OWASP Top 10 and access control checks. You can integrate it into your development phase to identify and resolve vulnerabilities before they can be exploited in production.

Moreover, it offers unique features like screen capturing in scan logs to help your team quickly validate authentication and assess product coverage. The platform is designed to be a disruptor in the stagnant security market by offering a fast, easy-to-use interface that fits naturally into modern stacks. If you are building serverless applications or heavily using GraphQL, Escape provides the specialized testing and remediation code snippets you need to keep your APIs secure.

Salt Security offers a patented API protection platform that uses big data and artificial intelligence to discover, monitor, and secure your APIs throughout their lifecycle. It automatically creates a complete inventory of all your APIs, including legacy and shadow endpoints, by analyzing live traffic for potential posture gaps. You can leverage its unique API Context Engine to pinpoint and block attackers in real-time by correlating activities across millions of users and sessions.

Additionally, the platform provides your developers with specific hardening insights to improve API security during the build phase. It excels at detecting subtle business logic abuses that traditional signature-based tools often miss. While the tool is highly effective for regulated industries that need deep visibility, it remains simple to deploy without requiring agents or app changes. This makes it a suitable choice for organizations that need a proven, AI-driven solution for high-volume API environments.

Wallarm is an API security platform that combines automated vulnerability testing with real-time threat protection to safeguard your cloud-native applications.
