Cloud computing changed everything \u2014 how we store data, collaborate, and build applications.<\/p>\n
But it also created a massive blind spot<\/strong> for security teams.<\/p>\n Employees now access corporate data from:<\/p>\n Laptops and smartphones<\/p>\n<\/li>\n Public Wi-Fi<\/p>\n<\/li>\n Third-party apps<\/p>\n<\/li>\n Personal devices (BYOD)<\/p>\n<\/li>\n<\/ul>\n And most of it happens outside the firewall.<\/strong><\/p>\n Enter Cloud Access Security Broker (CASB)<\/strong> \u2014 a key technology to help secure your journey to the cloud.<\/p>\n A Cloud Access Security Broker (CASB)<\/strong> is a security solution that sits between cloud service users and cloud applications<\/strong> to enforce security policies.<\/p>\n Think of it as a gatekeeper<\/strong> between your users and SaaS platforms like:<\/p>\n Microsoft 365<\/p>\n<\/li>\n Google Workspace<\/p>\n<\/li>\n Salesforce<\/p>\n<\/li>\n Dropbox<\/p>\n<\/li>\n AWS, Azure, and more<\/p>\n<\/li>\n<\/ul>\n CASBs give you visibility, control, and protection<\/strong> over data stored and accessed in the cloud.<\/p>\n Cloud adoption is no longer optional.
