The 10 Hottest Cloud Security Startup Companies Of 2024 (So Far)

Early-stage vendors focused on protecting data and GenAI usage in the cloud are among the year’s most notable cloud security startups.

While securing cloud environments continues to grow as a concern for organizations, the arrival of generative AI introduces—or intensifies—a number of challenges for protecting the cloud. When it comes to data security, for instance, GenAI systems rely on massive datasets that can include sensitive information, making the privacy and security of data an even bigger priority as AI-related initiatives increase.

That has prompted continued demand for new cloud security capabilities that offer differentiated approaches to protecting cloud and AI, and a number of up-and-coming startups are looking to meet the needs. Notably, many of these startups are placing a priority on working with channel partners even from the early phases of their sales efforts.

At cloud security startup Upwind Security, for example, the company has been focusing on driving its growth through solution and service provider partnerships, said Upwind Co-founder and CEO Amiram Shachar. “I’m a big believer in channel,” Shachar said. Partnerships have included both with smaller VARs as well as major solution and service providers, he said. “Most of our big accounts that we have right now came from channel,” Shachar said.

To be included on the list that follows, startups must have been founded since 2019. (Note: We’re also omitting cloud security startups that have already achieved significant scale such as Wiz and Orca Security.)
