According to Gartner, "digitalization, work from anywhere and cloud-based computing have accelerated cloud-delivered SASE offerings to enable anywhere, anytime access from any device. Security and risk management leaders should build a migration plan from legacy perimeter and hardware-based offerings to a SASE model".

Gartner predicts that "by 2025, at least 60% of enterprises will have explicit strategies and timelines for SASE adoption encompassing user, branch, and edge access, up from 10% in 2020".

Gartner's key findings:

• "To protect anywhere, anytime access to digital capabilities, security must become software-defined and cloud-delivered, forcing changes in security architecture and vendor selection"
• "Enterprises that consider existing skill sets, vendors, and products and timing of hardware refresh cycles as migration factors will reduce their secure access service edge (SASE) adoption time frame by half"
• "SASE is a pragmatic and compelling model that can be partially or fully implemented today
