At NWOSS, service is our first priority. Our experts are available 24 – 7 – 365 for service and support. We maintain high-quality customer satisfaction with prompt responses to all requests. But don’t just take our word for it. See what our customers have to say!

I have been with Yaskawa Motoman Robotics since we started the company over 30 years ago and I have been working with NWOSS for over 20 years. We worked with a couple of other security vendors early on and quickly learned that you get what you pay for, (poor equipment, installation, and service)! Since working with NWOSS our company has grown into a large international organization with facilities throughout the US, Canada, Mexico, and Brazil. NWOSS has grown with us and has always been there for us when we need them. They have an excellent, knowledgeable staff, impeccable customer service and a wide -ranging product line to choose from. If you or your company needs security and/or fire protection you need to contact NWOSS. They are a first-rate organization. I would recommend them without reservation and that is something I very rarely do.

The people from NWOSS have been absolutely fantastic in helping the Lima Public Library with our new camera security system provided by NWOSS. From sales, installation, and through activation and use of our cameras: the friendly and knowledgeable staff from NWOSS continue to provide fast & courteous service for any needs that arise or questions we have. NWOSS assured us and proved to us that they’ll continue to be of service long after the sale. Thanks NWOSS!

One of your guys came out and replaced our backup battery yesterday. We’ve had a couple issues recently with the system but nothing unrealistic, and Cory’s responsiveness and corrective actions have been phenomenal on every occasion. Our COO is singing your praises and our CEO was just mentioning whether you offer residential services since he’s seen your personalized service has outperformed your competitor’s (his home provider). Nice work by the whole team at NWOSS. Thanks for the amazing service and support and backing up my faith in selecting NWOSS for our security.

Thanks for lining up help for my Milestone server. With the help of your support technician we were able to diagnose the issue (bad drive in raid set) and then I was able to get a replacement from my server vendor and resolve the issue completely. Thanks again for the assistance.

Thank you for your efforts last week in developing a custom solution to assist Westfield and the Security team in order to deploy the necessary changes due to the recent pandemic. You worked tirelessly on changes to access control configurations and access profiles. You created a pandemic lockdown feature with one button control from the SOC, reprogrammed all facilities and built a pandemic employee profile. Additionally, you developed an operational video and an instruction manual to provide direction to all security staff, since we have 24/7 coverage and instruction needed to be communicated to all staff regardless of their shift. This tremendous level of cooperation and assistance speaks to your personal commitment to getting the job done and understanding what it takes to implement a successful solution.
