🧾 Definition
Colocation means renting space in a third-party data center to host an organization’s servers and networking equipment. It shifts some physical infrastructure responsibilities to the provider while leaving security and operations responsibilities with the customer.
🔑 Key Points
- Shared responsibility applies to power, cooling, physical access, and connectivity.
- The provider typically manages facility controls, while the customer manages equipment and application security.
- Contracts should define uptime commitments, access procedures, incident response, and audit rights.
- Physical security controls include guards, badges, cameras, and environmental monitoring.
⚠️ CISSP Insight
- Colocation reduces infrastructure burden but does not reduce the need for strong governance and control oversight.
- Organizations should verify that the provider’s controls align with their regulatory and business requirements.
⚔️ Key Difference / Trap
- Colocation vs cloud
- Colocation = you still manage the equipment in a provider’s facility
- Cloud = provider usually manages more of the underlying infrastructure
- Provider controls are not automatically your controls
- Contract and assurance evidence matter
🏗️ Example
An organization moves its servers into a colocated data center and retains responsibility for patching, monitoring, and access management while relying on the provider for power and facility security.

🔁 Quick Recall
- Colocation = rented facility space
- Shared responsibility = still your security responsibility
