60 or so people, with three locations. We have about 80 systems if we're talking client computers, servers, VMs, etc. This is also including the IP phone system, AD, etc as well.

I also take care of re-mediating security threats based off a third party assessment. This usually has me editing the GPO and writing small batch or powershell scripts as tasks that run on login.

We have a budget but it is very tight from what I experienced so far. I've used my own drill and other tools on occasions because we didn't have them at the location I was at.

I've also built a network monitor using Grafana, InfluxDB, Telegraf, and an ELK stack as well since there was none in place.

I'm the sole sysadmin/support and then we have two programmers and then the CTO.
