API Security: Market Landscape

Hackers increasingly target APIs as the gateway to an organization’s sensitive information.

March 21, 2023 – APIs have been around for over 20 years. Today, the average number of APIs organizations use can range from 15,564 to 25,592, making APIs one of the largest known software components of an enterprise attack surface. Imagine not knowing what functions many of those APIs perform, how many versions exist, or that they even exist. On the one hand, APIs give application development teams great power, but on the other, they introduce potentially significant vulnerabilities.

This Impact Report serves as a primer for CISOs on API security and provides API vendors with a view of the market not previously disclosed by market research firms. Primary research involved interviewing select API security vendors (primarily located in Israel, the U.K., and the U.S.) from December 2022 through March 2023, and receiving product demonstrations to validate market assumptions and define a product categorization schema. Desk research also included white papers, API security standards, and industry publications.
