How to Increase Engagement with Your Cybersecurity Clients Through vCISO Reporting

Jul 22, 2024vCISO / Business Security
As a vCISO, you are responsible for your client's cybersecurity strategy and risk governance. This incorporates multiple disciplines, from research to execution to reporting. Recently, we published a comprehensive playbook for vCISOs, "Your First 100 Days as a vCISO – 5 Steps to Success" , which covers all the phases entailed in launching a successful vCISO engagement, along with recommended actions to take, and step-by-step examples.  Following the success of the playbook and the requests that have come in from the MSP/MSSP community, we decided to drill down into specific parts of vCISO reporting and provide more color and examples. In this article, we focus on how to create compelling narratives within a report, which has a significant impact on the overall MSP/MSSP value proposition.  This article brings the highlights of a recent guided workshop we held, covering what makes a successful report and how it can be used to enhance engagement with your cyber security clients.
