Reddit User Seeks Advice on Building a Security Stack for Small Start-ups with High Requirements and Low Budget

A Reddit user is seeking advice on creating a security stack for two start-ups with a limited budget but high security needs. The start-ups have between 3 and 15 employees, use BYOD devices (Macs, iPhones, and Windows) and services like Google Workspace, Slack, and Microsoft 365. The goal is to secure identities and devices with technical solutions that are preferably free or low-cost and easy to implement.
