Foss Security

We have been with Foss since we moved to Sioux Falls last summer and they are great! The install was smooth and when some of the tech needed adjusting, they were all over it! They didn't try to oversell anything! Great company, highly recommended for your security needs!

After a frightening night where we experienced an attempted break in of our patio door, I called Foss . They came over that morning and had our system installed by early afternoon. (They were patient with a not very tech savvy old woman!) I appreciate feeling safe now and highly recommend them!

Foss Security have been exactly like you hope companies would be. They're quick to respond and knowledgeable. When we've called, they were able to handle all questions over the phone and walked us through how to do what we need ourselves with our system. Highly recommend Foss if you're thinking about installing a home monitoring system.
