Managed Service Provider (MSP) executives have noted a surge in interest in SASE, even among smaller businesses. David Gottesman, CEO of Epic Machines, emphasized that the demand for SASE solutions is "alive and well," indicating a robust market for these services.

Gartner’s 2024 Magic Quadrant report further underscores this trend, identifying key players in the SASE market. Palo Alto Networks, Cato Networks, and Netskope have been recognized as leaders, while Fortinet and Versa Networks are noted as challengers. Cisco stands out as a visionary, and several other companies, including Hewlett Packard Enterprise and Cloudflare, are acknowledged as niche players. This competitive landscape illustrates the dynamic nature of network security and the ongoing innovation within the sector.
