Our experience with GRS has been outstanding
We got burned by our last IT company, before GRS took over, and I have to say that the money we spend each month on GRS is worth every penny. We learned not to base anything in the IT field on money, since we are always looking for the best results, which means to put forth the best people for the job. Having a dedicated IT provider, has helped reduce down time and workflow disruption making the added cost worth the investment.
Before bringing on GRS to monitor our network, we received on three different occasions some ransomware or Crypto Virus and our company lost 100+ man hours just restoring from backups before GRS stared monitoring our network. GRS always stays ahead of the game on Remote Management and antivirus software and from my perspective, that is something priceless that you usually don't get with other IT companies.
