Here is your reality check on the cloud security market

Cloud security is hot right now, and investors are writing some of the largest checks in cybersecurity.

We've found a lot of interesting signals. For example, in January 2026, Upwind, which protects cloud applications while they run, raised $250M at a $1.5B valuation. That same month, Cyera, which finds and protects sensitive data across cloud services, raised $400M at a $9B valuation, triple what it was worth a year earlier. Even after the big platform deals, investors are betting that cloud security is far from settled.

In this section, we look at why cloud security is still drawing so much money, which problems buyers want solved now, and where that leaves room for new players.

Most companies now run on several clouds, and few security teams can see everything they've deployed.

We compare six types of cloud security companies, from posture and workload protection to permission management, container security and cloud detection and response. Their buyers range from fast-growing software companies to banks and governments. For each, we rank the biggest pains, like too many alerts, accounts with far more access than they need, mistakes in setup files and too few people who know cloud security.

This shows which problems a security team will pay to fix this year, and which ones it will keep living with.

Pricing per workload or per cloud asset, platform subscriptions, usage-based detection, and sales through cloud marketplaces: cloud security companies charge in many ways.

We compare the payer and the cost behind each model. Pricing per workload grows with the customer's cloud, but buyers push back when the bill jumps. Tools that install an agent on each workload cost more to deploy than agentless scanners, but see more. And selling through the cloud providers' marketplaces makes buying easier, while the providers take a cut and sell security tools of their own.

You'll see which models keep their margins when buyers move to fewer platforms, and which ones get squeezed.

We give our own growth estimate for cloud security, and this section shows what stands behind it.

Some drivers are plain to see: more workloads in the cloud, AI projects that need large amounts of data, and more attacks on cloud accounts. Others build on each other. Each new cloud service adds something else to protect. Stricter breach reporting rules push boards to ask harder questions. And once a team trusts one tool to see its whole cloud, it tends to give it more jobs.

Before building or investing, you should know what makes a security team move from finding cloud risks to fixing them, and keep paying for it year after year.

Orca Security and Upwind come up quickly when people talk about cloud security specialists, but the market reaches well beyond them.

Many of the most interesting players stick to one narrow job. Some only check infrastructure code before it's deployed. Others clean up cloud permissions, watch Kubernetes clusters for attacks, or map where AI models and agents run inside a company's cloud.

They're hard to compare because almost every vendor now claims to cover the whole cloud. One may scan settings once a day, another may watch every running workload, and buyers often see the difference only after a trial. Many are also bought through a cloud marketplace or as part of a bigger platform.

Below, you'll find the market grids and ecosystem maps we've built to show who protects which part of the cloud, and where new players are getting in.

Aqua Security, Sysdig, Sweet Security… a few specialists have built real businesses next to the big security platforms.

Aqua Security grew with containers and Kubernetes, and offers open-source tools that many developers already use. Sysdig built its name on watching what runs in the cloud in real time. Sweet Security, much younger, is betting on runtime protection for cloud and AI workloads. None has shown yet that it can stay independent while the large platforms keep buying their way into the market.

We'll look at how these teams won over developers first, earned a place in security teams' daily work, and stayed relevant as buyers cut down their list of vendors.
