We acknowledge that engaging sub-processors in GDPR Data chain might potentially introduce certain risks if not managed properly, which is why Delta Green takes a structured and diligent approach to managing them. Before entering into any relationship with an external vendor, we conduct a thorough assessment of the potential risks and impacts associated with that engagement according to ISO 27001 requirements.

Any sub-processor with access to data managed by Delta Green is required to provide clear documentation of their security policies, processes, and procedures. They must be able to demonstrate that they can ensure an appropriate level of protection for such data – including safeguards against misuse or compromise.

Vendors working with Delta Green must maintain robust information security programs, aligned with industry best practices and relevant legal requirements, to protect confidential and personal data. This includes strong technical and organizational safeguards, secure system configurations, controlled physical and logical access, encryption, regular monitoring and audits, timely incident response, and reliable business continuity measures. Vendors are expected to demonstrate compliance with these standards and ensure any third parties they engage do the same.
