This document summarizes a presentation given by an executive from a managed security services provider (MSSP) about engaging an MSSP for security services. It begins with a poll asking about current and past MSSP usage. The presentation then discusses why organizations use MSSPs, focusing on lack of internal skills, resources, and scale. It uses a case study of "Bob and Alice" to illustrate common struggles between MSSPs and clients around communication and expectations. The rest of the presentation outlines key areas for MSSPs to focus on, including technical capabilities, onboarding process, managing alerts and investigations, and defining service level agreements and contract terms.
