Executive Summary

As organizations navigate the complexities of hybrid cloud and on-premises IT environments in 2025, encryption posture management has emerged as a critical discipline for data protection. This whitepaper examines the key challenges and best practices for implementing comprehensive encryption strategies across diverse infrastructure landscapes.

The research reveals that 82% of cloud security breaches stem from misconfigurations, with 55% of organizations finding cloud encryption more complex than on-premises implementations. Organizations face significant challenges including fragmented key management across silos, inadequate visibility into encryption coverage, and the looming threat of quantum computing to current cryptographic standards.

Best practices emerging from industry leaders include establishing centralized encryption governance, implementing automated key lifecycle management, adopting zero-trust encryption architectures, and preparing for post-quantum cryptography. Organizations achieving success have reduced breach risks by up to 50% through unified encryption posture management platforms and continuous monitoring.

This whitepaper provides CISOs and security leaders with actionable insights for developing resilient encryption strategies that address both current threats and future challenges while maintaining operational efficiency across hybrid environments.
