The future of the SASE industry is rich with transformative and highly lucrative Secure Access Services Edge Market Opportunities that extend far beyond the current focus on securing remote workers and branch offices. The most significant of these future growth vectors lies in extending the SASE security model to protect the vast and rapidly expanding universe of non-human entities: the Internet of Things (IoT) and Operational Technology (OT). The modern enterprise network is no longer just comprised of users and their laptops. It is now teeming with millions of connected devices, from smart sensors and security cameras in a "smart building" to industrial control systems and robotic arms on a factory floor. These IoT and OT devices are often built with minimal security, cannot run a traditional security agent, and are becoming a massive new attack surface. There is a colossal opportunity for SASE vendors to develop specialized solutions to secure this traffic. This would involve using AI to automatically discover and profile these "headless" devices, and then applying a strict, Zero Trust policy to ensure they can only communicate with the specific applications and servers they are authorized to, effectively "micro-segmenting" them on the network to contain any potential breach. Securing the IoT/OT edge is a massive greenfield opportunity.
A second major opportunity lies in moving "up the stack" to provide more advanced, inline data security capabilities. The current generation of SASE platforms are primarily focused on access control (who can connect to what) and threat prevention (blocking malware and malicious websites). The next frontier is to provide much deeper, real-time visibility and control over the sensitive data that is flowing through the SASE cloud. This involves the deep integration of advanced Data Loss Prevention (DLP) technology directly into the single-pass SASE architecture. This would allow the platform to inspect all data in motion—whether it's going to a SaaS application, a private application, or the public web—to detect and block the exfiltration of sensitive information, such as credit card numbers or intellectual property. This would transform the SASE platform from being just a secure access solution to being a comprehensive, real-time data protection platform, a much more powerful and valuable proposition for any CISO concerned about data breaches.
A third key opportunity, and one that is critical for long-term growth, is in better serving the massive, and largely underserved, small and medium-sized enterprise (SME) market. While the early adopters of SASE have been large enterprises, the security and networking challenges that SASE solves are just as, if not more, acute for SMEs, who lack the budget and in-house expertise to manage a complex security infrastructure. The opportunity lies in creating a simplified, lower-cost, and channel-friendly version of SASE that is designed for the needs of the SME. This would involve a much more streamlined and automated onboarding process, a more intuitive management interface, and a business model that is built to be sold and delivered by the thousands of Managed Service Providers (MSPs) who are the trusted IT advisors to the SME market. The company that can successfully "democratize" SASE and make it accessible to the vast SME segment will unlock a huge new engine of market growth. The Secure Access Services Edge Market size is projected to grow to USD 42.86 Billion by 2035, exhibiting a CAGR of 22.1% during the forecast period 2025-2035.
