How big are security teams at your job?

Title says it all but to give a little more background. I’ve been in cyber security for 4 years now. I spent 3 at a Fortune 10 company and the last year has been at a company with less than 300 employees. Left for better pay but the security team I’m on is only 3 people at the workload is insane.

Just looking to get perspective from others who have been in the field longer. Is it common for companies that size to have such small security teams?
