The BEST security service company in Atlanta. This company has gone above and beyond my expectations. We had a break-in a few years back and their response and handling was amazing. Awesome rates and great service. 10/10

Absolutely the best security in all of metro Atlanta. I have been fortunate to be a customer of CMS Security Services for the last 10 years. The whole team is beyond wonderful. Do yourself a favor and choose CMS Security Services as your security provider, you won't be disappointed!

Beware of this company! They will try to take advantage of you and overcharge you for repairs! Wish I could give them 0 stars

I'm extremely unhappy with the customer service I received today after being a customer since 2000. I understand that CMS acquired the original company I signed up for service, but to double my rates and be rude over the phone is uncalled for when I requested for my service to be transfer. I've already found another alarm company that will be happy to activate my new house at similar rates that I was paying CMS. Additionally, they did not implied that they were doing me a favor to monitor my house, but actually appreciated getting my business. I guess CMS did not value me as a customer and told me to take their offer or cancel my service. I will take their advice and leave.
