The perimeter is no longer sufficient in the face of teleworking, BYOD, third-party providers, and Shadow IT. With just one compromised connection, the attacker can roam freely as if in conquered territory. The response is a culture of access: real-time decisions based on context rather than network affiliation. Insights from the latest CESIN barometer confirm a persistent reality: the trio of phishing, exploiting vulnerabilities, and attacks via third parties remains the dominant vector of cyberattacks, with data theft as a major consequence in 52% of cases. This underscores the limitations of a perimeter security where network access often equates to blind trust.
In a dispersed work environment, the challenge now is to refine control based on each user’s profile. This is where the SASE architecture comes into play. While SASE is a well-known pillar of cloud and network architecture, attention still often focuses only on infrastructure issues. Security is just as crucial, from firewalls to inspection layers, just like the Edge. This encompasses SD-WAN, packet routing, user location, and connection methods.
These elements are indeed essential. It is impossible to implement next-generation security if threats cannot be neutralized and rules applied before data reaches the network or cloud applications. Yet, the “Access” aspect of the acronym is often understated, even though it constitutes the differentiating element of the SASE architecture. It governs the entirety of the connection context: from user identity and device to destination, schedule, and purpose.
