GDPR and ISO 27001: how to make them work together successfully
The GDPR sets legal requirements for the protection of personal data; ISO 27001 provides the management system with which you control security in a structured way. They overlap strongly on security measures and reinforce each other: ISO 27001 makes a large part of the GDPR security obligation demonstrable and repeatable.
Where do they overlap, where do they differ?
ISO 27001 covers access management, risk assessment, incident management and continuity — all relevant to the GDPR. In addition, the GDPR requires specific privacy matters: a legal basis, the rights of data subjects, a record of processing activities and DPIAs. You add that privacy layer with ISO 27701.
Practical approach
Build privacy on top of your ISMS: link the GDPR obligations to existing controls and supplement them where needed. A privacy gap analysis shows where you stand. See also how ISO 27001 and NIS2 relate to each other.

Not automatically. ISO 27001 largely covers the security side of the GDPR, but the GDPR also requires privacy-specific matters such as a legal basis, a record of processing activities, DPIAs and the rights of data subjects. With ISO 27701 on top of your ISMS, you make that privacy control demonstrable.
ISO 27001 focuses on information security in a broad sense. ISO 27701 is an extension that adds a privacy management system (PIMS), focused on the processing of personal data. Together they cover both security and privacy, which aligns well with the GDPR.
Yes. ISO 27001 requires incident management and recording, so you detect, respond and act demonstrably more quickly in the event of a data breach. This directly supports the notification obligation that the GDPR prescribes.
