“The decision to use cloud UEM isn’t about whether data will be exposed—it’s about understanding exactly what data is exposed, to whom, and under what circumstances, then implementing appropriate controls to manage those risks.” – Privacy and Security Architect
Organizations should approach cloud UEM adoption with a clear understanding of their data landscape, implement appropriate privacy and security controls, and maintain ongoing vigilance to ensure their data protection posture remains aligned with their risk tolerance and regulatory obligations.
