How We Evaluated the Top Cloud Security Companies

In evaluating the cloud security market, we examined the breadth and quality of each vendor’s products and services, customer reviews, analyst reports, market traction and growth, independent test reports, pricing, and more.

Understanding Cloud Security Technologies

When considering cloud security products, it’s important to recognize and understand the different categories of solutions that are available to help organizations reduce risk and improve security. Among them are:

  • Cloud access security brokers (CASB): A primary category of cloud security solutions is cloud access security broker (CASB) platforms, which monitor activity and enforce cloud access security policies. For more on CASB vendors, see our guide to the top CASB vendors.
  • Cloud workload protection platforms: Cloud workload protection technologies (CWPPs) work with both cloud infrastructure and virtual machines, providing monitoring and threat prevention features.
  • Cloud-native platforms: Cloud-native application protection platforms (CNAP or CNAPP) combine cloud security posture management (CSPM) and CWPP in a single, unified solution to provide visibility and security control management across all cloud functions.
  • SaaS security: Multiple types of security technologies are also delivered as a service from the cloud, to help secure both on-premises and cloud workloads.

It’s also important to note that each of the major public cloud providers (Amazon Web Services, Google Cloud Platform and Microsoft Azure) also have their own native cloud security controls and services that organizations can enable. Understanding your responsibilities on these platforms under the shared responsibility model of cloud security is critically important.

Choosing a Cloud Security Company

With the wide variety of options available for users, it can often be a confusing and time-intensive task to select an appropriate offering. When looking at cloud security, there are several key considerations:

  • Scope: It’s important to understand what’s at risk and what the organization is trying to protect. Often one or more services will be needed to protect an entire cloud deployment.
  • Policy Integration: Making sure that a given cloud security solution can integrate with existing policy systems, whether they are on-premises or in the cloud, is important for enabling a uniform policy for an enterprise.
  • Multi-Cloud Protection: The ability to work across multiple cloud providers and different types of deployments is important, since few organizations want to be locked in to any one vendor or cloud.

Bottom Line: Cloud Security Companies

As companies increasingly store and process critical data and assets in the cloud, it’s important that they have the right cloud security tools to secure those assets.

Cloud security companies give businesses the security solutions to meet those needs, ranging from risk assessment, auditing, data encryption, user authentication, access control, and more. They can also advise on how best to secure cloud systems and protect data.
