The 20 Coolest Network Security Companies Of 2024: The Security 100 – CRN

5 minutes, 57 seconds Read

From vendors offering SASE platforms to those focused on protecting IoT and connected devices, here’s a look at 20 key network security companies.

As anyone paying attention will know, the erosion of the corporate network firewall has led to a massive shift in the network security market over the past decade — particularly since the adoption of remote and hybrid models of work among many employers. The result has been an acceleration in the embrace of the secure access service edge (SASE) model by many vendors that had formerly specialized in next-generation firewalls (such as Palo Alto Networks, Fortinet and Cisco).

Meanwhile, other vendors that had gotten their start in SD-WAN (such as Cato Networks) have now become major players in SASE as well. SASE integrates security components such as zero trust network access (ZTNA), secure web gateway (SWG) and cloud access security broker (CASB) capabilities with SD-WAN to enable secure remote access to applications, data and other corporate resources.

Outside of SASE, other major vendors helping to protect extended modern networks — often including IoT and operational technology (OT) systems — include Armis, Claroty, Dragos and Forescout.
