"We're excited to bring RSSI into the Global GRAB family of brands and continue delivering innovative security solutions to our customers."

"This acquisition is about more than expanding our product portfolio," said Mark Horne, Chief Executive Officer of Global GRAB. "It brings together two organizations with a shared commitment to innovation, engineering excellence and protecting people, critical infrastructure and national assets. By combining our expertise, we are better positioned than ever to deliver comprehensive perimeter security solutions that address today's evolving threats."
