F5 Distributed Cloud API Security is a SaaS platform that discovers, tests, monitors, and protects APIs throughout their lifecycle across public cloud, on premises, and hybrid environments. It maps APIs using traffic analysis, code repository scanning, and external crawling, automatically generating OpenAPI specification files even for undocumented shadow APIs.
The platform detects and blocks OWASP API Top 10 attacks in real time, using machine learning behavioral baselines to flag anomalies and score authentication risk. It also detects and masks sensitive data such as PII and PCI, HIPAA, and GDPR-regulated information, and offers an AI assistant for natural-language investigation of events. Pricing is consumption-based and quote-driven, with free trials available and pay-as-you-go options on AWS Marketplace.

AI-powered API and agentic security platform for discovery, posture and runtime protection.
Salt Security is an API security platform that discovers all APIs across an organization, including shadow and zombie APIs, and uses patented AI and machine learning to detect anomalous behavior and stop attacks in real time. Its Agentic Security Graph extends this to map AI agents and MCP servers alongside APIs, giving security teams visibility into what agents are doing and the ability to intervene. The platform also analyzes API design in pre-production and provides posture governance and remediation guidance.
Founded in 2018 and headquartered in Palo Alto, California, Salt Security serves large enterprises in finance, healthcare, retail and transportation, including customers such as Hyundai and SoFi. Pricing is not publicly listed and is customized to traffic volume and deployment scope, though third-party marketplace listings suggest six-figure annual contracts are typical.
