The 25 Hottest Edge Security Companies: 2026 Edge Computing 100
As part of CRN’s Edge Computing 100 for 2026, here are 25 security vendors working to protect users and data across IT, OT and IoT environments.
As industrial systems become increasingly interconnected—while AI agents continue to take on more and more tasks—security experts say there is no question that protecting edge environments is becoming a steeper challenge.
Businesses that rely on edge, OT (operational technology) and IoT systems must also make sure to protect their sensitive data while securing equipment that is essential for critical processes.
For customers in the industrial sector, edge security needs extend far beyond prevention of data theft, according to Patrick Gillespie, OT practice director at Herndon, Va.-based GuidePoint Security, No. 32 on CRN’s 2026 Solution Provider 500.
“The issue in OT is keeping everything running,” Gillespie said. “It’s about keeping your people safe, and then keeping your systems safe. So OT cares about uptime—just keep it running at all costs. We’re not protecting the data [in the same way] as in IT.”
Other key differences from IT security include the challenge of visibility on the edge, Gillespie told CRN. For instance, connections installed for remote maintenance can actually leave industrial equipment vulnerable to attack—without the operator even realizing it, he said.
Across edge, OT and IoT environments, security vendors are responding to meet these critical needs with capabilities to uncover overlooked assets, prioritize exposures and restrict the movements of threat actors.
Meanwhile, SASE (secure access service edge) vendors are expanding capabilities in areas such as browser security and controls for AI agents.
