Master Service Agreement (MSA)
Definition
A Master Service Agreement is a contract that sets the general legal and commercial terms for an ongoing business relationship between two parties, usually a customer and a supplier. It creates the baseline rules for how services will be delivered, how risk and responsibilities are handled, and how future work will be governed without renegotiating the same core terms each time.
Examples
- A company signs an MSA with a managed service provider so future projects can be started quickly under agreed legal and security terms.
- A software vendor and customer use an MSA to define liability, confidentiality, payment terms, and data handling expectations before any detailed project work begins.

When organizations buy services, they usually do not want to negotiate every legal detail from scratch each time new work begins. A Master Service Agreement solves that problem by setting the ground rules once, then allowing future work to be added under those same rules.
From a security and governance point of view, the MSA matters because it often defines who is responsible when something goes wrong, how confidential information must be protected, and what happens if a supplier causes harm or fails to meet agreed expectations.
