Executive Summary
The procurement landscape has fundamentally shifted. What was once a straightforward vendor selection process now represents one of the most critical cybersecurity frontlines for modern enterprises. With supply chain attacks accounting for a significant rise in breaches throughout 2024 and into 2025, Chief Information Security Officers (CISOs) face an unprecedented challenge: how to conduct effective cyber due diligence during procurement while balancing business velocity, regulatory compliance, and evolving threat landscapes.
This whitepaper synthesizes the latest developments in cyber due diligence practices, drawing from recent regulatory frameworks including NIST CSF 2.0, the EU Cyber Resilience Act, and DORA requirements that became binding in January 2025. Our analysis reveals that organizations implementing comprehensive cyber due diligence frameworks can reduce breach risks by up to 40% while ensuring compliance with an increasingly complex regulatory environment.

Key findings demonstrate that success requires more than technical assessments. Organizations must embed cyber due diligence into their procurement DNA through precise requirement specifications, continuous monitoring, cross-functional collaboration, and automated risk quantification tools. The most effective approaches combine proactive frameworks with practical implementation strategies, moving beyond checkbox compliance to create genuine cyber resilience.

For CISOs navigating this landscape in 2025, the message is clear: cyber due diligence in procurement is no longer optional. It has become a strategic imperative that directly impacts enterprise resilience, regulatory compliance, and competitive advantage. Organizations that master this discipline will thrive in an interconnected digital economy, while those that treat it as an afterthought risk becoming the next headline.
