Background for this topic.

An acquisition is the purchase of a company, business unit, or technology by another organization, transferring control of its people, systems, and data. In information security, the event matters because the buyer may inherit unfamiliar networks, cloud services, software, credentials, suppliers, and unresolved security issues.

Before integration, security due diligence should identify exposed systems, critical vulnerabilities, active threats, prior incidents, and obligations governing personal or regulated data. After closing, teams must control access between environments, remove unnecessary accounts, verify asset ownership and logging, and bring inherited systems into vulnerability-management and monitoring processes. Connecting legacy infrastructure too quickly can create new attack paths, while poorly planned changes can hinder detection or incident response. Privacy and compliance reviews should confirm that data use, retention, and cross-border transfers remain lawful under the combined organization.
