Overlooking cyber risks can erode deal value, damage reputation, and trigger regulatory penalties.<\/p>\n<p>This blog outlines critical challenges, hidden vulnerabilities, compliance pitfalls, and cultural misalignment\u2014and introduces a phased Secure acquisition Lifecycle Framework, from Pre-Day 1 through Operate, to safeguard integration and preserve enterprise value. Cyber due diligence must be treated as a strategic lever, not a technical checkbox, for achieving successful acquisitions.<\/p>\n<h5>Introduction<\/h5>\n<p>Acquisitions drive growth and market expansion, but they also introduce significant cybersecurity risks. Integrating two distinct technological ecosystems and governance models creates vulnerabilities that attackers actively exploit.<\/p>\n<p>Cybersecurity is no longer a technical detail\u2014it is a strategic imperative for protecting deal value. A proactive, risk-based approach during due diligence and integration is essential to ensure resilience and prevent costly disruptions.<\/p>\n<h5>Real World Lessons<\/h5>\n<ul>\n<li>UnitedHealth Group and Change Healthcare (2024): ALPHV\/BlackCat ransomware exploited MFA gaps compromising 100M+ health records and causing major operational disruption.<\/li>\n<li>Marriott &amp; Starwood (2018): Undetected breach exposed 500M guest records, resulting in \u00a318.4M GDPR fines and lawsuits.<\/li>\n<li>Under Armour &amp; MyFitnessPal (2018): Credential theft exposed 150M user accounts (emails, hashed passwords) after hackers accessed MyFitnessPal\u2019s database post-acquisition.<\/li>\n<\/ul>\n<h5>Key Insights:<\/h5>\n<ul>\n<li>You acquire the target\u2019s history, not just its future.<\/li>\n<li>Cyber risk doesn\u2019t pause for integration\u2014security must lead, not follow.<\/li>\n<li>You\u2019re not just buying assets; you\u2019re inheriting liabilities and latent threats.<\/li>\n<\/ul>\n<h5>Cybersecurity Challenges in Acquisition<\/h5>\n<p>Acquiring a company means inheriting its attack surface. Common challenges include:<\/p>\n<ul>\n<li>Legacy systems and outdated controls: Old infrastructure creates exploitable gaps.<\/li>\n<li>Misaligned security policies: Conflicting standards weaken governance.<\/li>\n<li>Third-party and supply chain risks: Vendor dependencies introduce hidden threats.<\/li>\n<li>Integration under time pressure: Accelerated timelines increase misconfigurations.<\/li>\n<li>\u00a0Cultural differences in security practices: Divergent approaches hinder consistent enforcement.<\/li>\n<\/ul>\n<p>These factors increase vulnerability during and after acquisition. Embed security across the acquisition lifecycle to reduce vulnerabilities and ensure compliance.<\/p>\n<h5>Secure Acquisition Lifecycle Framework<\/h5>\n<p>Four pillars guide secure integration:<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-1253 size-full\" src=\"https:\/\/blogs.infosys.com\/infosys-consulting\/wp-content\/uploads\/2025\/12\/Four-pillars-guide-secure-integration.png\" alt=\"\" width=\"548\" height=\"392\" \/><\/p>\n<h5>Approach for Acquisition Timeline<\/h5>\n<p>1.\u00a0\u00a0\u00a0 Phase 1: Pre Acquisition &#8211; Day 1: Due Diligence &amp; Planning<\/p>\n<p>2.\u00a0\u00a0\u00a0 Phase 2: Day 1: Acquisition Planning<\/p>\n<p>3.\u00a0\u00a0\u00a0 Phase 3: Days 1\u2013100: Integration<\/p>\n<p>4.\u00a0\u00a0\u00a0 Phase 4: Post Integration (Operate)<\/p>\n<p>&nbsp;<\/p>\n<h5><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-1254 size-full\" src=\"https:\/\/blogs.infosys.com\/infosys-consulting\/wp-content\/uploads\/2025\/12\/Approach-for-Acquisition-Timeline.png\" alt=\"\" width=\"595\" height=\"423\" \/><\/h5>\n<h5>Benefits obtained<\/h5>\n<p>1.\u00a0\u00a0\u00a0\u00a0\u00a0 Early Cyber Due Diligence \u2192 Prevents costly surprises by identifying security and compliance gaps before deal closure.<\/p>\n<p>2.\u00a0\u00a0\u00a0\u00a0\u00a0 Legacy System Risk Awareness \u2192 Reduces breach likelihood by proactively addressing exploitable vulnerabilities.<\/p>\n<p>3.\u00a0\u00a0\u00a0\u00a0\u00a0 Phased Integration \u2192 Ensures smoother IAM and network security alignment, minimizing disruption.<\/p>\n<p>4.\u00a0\u00a0\u00a0\u00a0\u00a0 Continuous Post-Close Monitoring \u2192 Maintains resilience and detects threats early, safeguarding long-term value.<\/p>\n<h5>Conclusion<\/h5>\n<p>Cybersecurity in acquisition is a race against time. Ignoring cyber risk can lead to catastrophic breaches, as seen in Marriott, Yahoo, and Change Healthcare. Acquisitions transfer not just assets but technology and risk &#8211; every system and vendor can be an entry point if not assessed. Shifting security left through due diligence and adopting a phased, structured approach ensures integration without inheriting hidden threats.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Cybersecurity has become a decisive factor in acquisition success.
