Why can't we just buy these tools and run them ourselves?

“Most firms try, and most stop. EDR, email security, MFA, patching, training, backups, and WISP documentation each come from different vendors with different dashboards and different on-call expectations. Someone in the firm becomes the de-facto security lead, and the controls drift the moment tax season hits. VeritGuard runs them as one managed service with a single response team.”
