Who We Are

Greenforce Security International was started by a retired police officer with the goal of bringing the same level of professionalism of officers found in the public sector into the private sector. We are changing the way people view security. As time goes on, police departments resources have been stretched thinner and thinner, and their ability to conduct proactive actions to prevent crime has become ever more diminished. This gap between what the community needs, and what the police are able to provide, grows larger every year. We fill the gap and strive to work alongside local law enforcement agencies to make our communities safer.

Our marked patrol vehicles are fully equipped with scanners, radios, spotlights, alley lights, tablets, body cams and satellite tracking hardware that will verify that each and every patrol was completed. This hardware is installed into our vehicles and shows the exact location and speed of our patrol cars every 30 seconds. Our clients can easily go into our web portal and confirm any patrol conducted.

We have a specifically designed patrol monitoring and reporting app, the Security Manager, which automatically forwards all patrol times and notes plus any incident reports with supporting documents directly to our clients in real time via email.
