The Evolving Role Of The Chief Security Officer (CSO): From Technical Guardian To Business Strategist
Security Boulevard, Monday, October 6th, 2025
When I first entered the world of cybersecurity, the role of chief security officer (CSO) was often relegated to the shadows with a primary focus on policies, compliance, and technical defenses. Fast forward to today, and the CSO's role has transformed dramatically.  
According to Splunk's CISO Report, 86% of CSOs and CISOs say that the role has changed so much since they started that it's almost a different job entirely. That's because today's CSO isn't just tasked with protecting their company's data - they're enabling business outcomes, influencing customer decisions, and even conferring a competitive advantage when it comes to generating sales.
My own professional journey reflects this shift. From my early days at Deloitte, where cybersecurity was a nascent practice, to leading security at global companies like Roche and now Commvault, I've seen firsthand how the CSO's responsibilities have expanded to become strategic business leaders, integral to driving organizational growth and customer trust.
