Outsourcing server/network alerts
I work at a MSP and right now we monitor a bunch of servers and network devices. I'm considering outsourcing the after-hours monitoring to a 3rd party, but I have limited experience in this area and am looking for recommendations. I would need this 3rd party to respond to any alerts within 15 minutes and either resolve the issue, or escalate the issue to my team. Competency is probably my biggest concern as I want to minimize escalations, and minimize the number of rookie mistakes that the 3rd party might make. Has anyone used a company in this arena that they loved?
