Evolution of Cloud Security Solutions
The cloud computing era began in 1999, when Salesforce proved the utility and popularity of SaaS (software as a service) applications with the launch of its CRM service. Amazon did the same thing for cloud infrastructure (IaaS) with the launch of AWS in 2006, and platform as a service (PaaS) offerings began to appear around the same time.
Securing all those new cloud environments and connections became a job for cybersecurity companies. Gartner played a big role in the development of cloud security terminology, coining the term “Cloud Workload Protection Platform” in 2010 to describe a tool used for safeguarding virtual machines and containers. In 2012, Cloud Access Security Brokers (CASB) began to emerge to monitor user access of cloud services.
Cloud Security Posture Management services (CSPM) began to appear in 2014 to manage cloud service configurations as cloud service providers like AWS, Microsoft Azure, and Google Cloud grew more prevalent. Identity discrepancies in account entitlements led to the rise of Cloud Infrastructure Entitlement Management (CIEM) a few years later, and in the last two years Cloud Native Application Protection Platforms (CNAPP) have emerged to tie together CWPP, CSPM and CIEM into a comprehensive cloud security platform.
We’ll take an in-depth look at each below.
