We strive to exceed your expectations

When you’re an SIS client, we supply you with a monthly report generated from our Smart Track and Secure-A Track software. The report contains data from the GPS technology fitted to our vehicles or carried by our officers at selected sites.

We will report our average response times, time on-site and other key performance indicators that will be set with you before we commence work.

Your dedicated SIS Customer Service Manager will meet with you every month to discuss the report and address any issues.
