Secure access service edge, or SASE (“sassy”), is an emerging cybersecurity concept that Gartner described in the August 2019 report The Future of Network Security in the Cloud.
Traditional network security is becoming insufficient to address the growing and changing vulnerabilities within the new workforce landscape. It simply cannot provide the levels of security and access control digital organizations need. Today, users are demanding access from anywhere, at any time, on any device. Providing secure access is becoming unmanageable. An increase in remote users, cloud-based software-as-a-service (SaaS) applications, and the varying directions and destinations of data traffic calls for a new approach in network and internal security management.
According to Gartner, “SASE capabilities are delivered as a service based upon the identity of the entity, real-time context, enterprise security/compliance policies and continuous assessment of risk/trust throughout the sessions. Identities of entities can be associated with people, groups of people (branch offices), devices, applications, services, IoT systems or edge computing locations.”
Gartner expects that, “by 2024, at least 40% of enterprises will have explicit strategies to adopt SASE, up from less than 1% at year-end 2018.” A SASE architecture identifies users and devices, applies policy-based security, and delivers secure access to the appropriate application or data. This approach allows organizations to apply secure access no matter where their users, applications or devices are located.
The SASE security model can help your organization in several ways:
- Flexibility: With a cloud-based infrastructure, you can implement and deliver security services such as threat prevention, web filtering, sandboxing, DNS security, credential theft prevention, data loss prevention and next-generation firewall policies.
- Cost savings: Instead of buying and managing multiple point products, utilizing a single platform will dramatically reduce your costs and IT resources.
- Reduced complexity: You can simplify your IT infrastructure by minimizing the number of security products your IT team has to manage, update and maintain, consolidating your security stack into a cloud-based network security service model.
- Increased performance: With a cloud infrastructure, you can easily connect to wherever resources are located. Access to apps, the internet and corporate data is available globally.
- Zero Trust: A Zero Trust approach to the cloud removes trust assumptions when users, devices and applications connect. A SASE solution will provide complete session protection, regardless of whether a user is on or off the corporate network.
- Threat prevention: With full content inspection integrated into a SASE solution, you benefit from more security and visibility into your network.
- Data protection: Implementing data protection policies within a SASE framework helps prevent unauthorized access and abuse of sensitive data.
