Securus Inc., was a Cary, North Carolina–based provider of GPS tracking and personal emergency response technology.

[8] Zoombak, Inc was known for developing GPS-based products that help people track things, ranging from teenage drivers to employees, pets and automobiles.

In March 2015, it was announced that Securus was selling its personal emergency response service (PERS) platform to Ogden, UT–based Freeus, LLC, sister company of AvantGuard Monitoring Systems.

[9] That same month, it was announced that BrickHouse Security acquired Securus, including Zoombak and related brands.

[11] This has been raised as a privacy concern as it allows Securus to sell for its own profit the "location of nearly any phone in the US without authorization," including to bounty hunters.
