Digitization and connectivity are at the core of every business activity today. Ensuring secure access to data and systems is therefore invaluable. SASE stands for: Secure Access Service Edge and offers a completely different approach to network security and connectivity. Traditional boundaries blur as it sets a new standard for efficiency and security.
In this blog, we delve deeper into the essence of SASE, reflect on the functionalities it offers and explore the benefits your business can experience through its implementation.
For years, network & security was centered around the corporate network, seen as the secure perimeter. However, this model is no longer tenable today. More people are working remotely and more companies are embracing the cloud. This trend significantly impacts the scale of your corporate network and its data security. The traditional, centralized hub-and-spoke network architecture has become an expensive affair and consequently creates various security risks.
Moreover, your business needs to easily adapt to rapidly changing and new demands. This requires flexibility, particularly concerning security. Relying on perimeter security would significantly hinder productivity. It would be necessary to route all traffic to the data center, which is not only cumbersome but also challenging to achieve.
Therefore, the need for a network and security architecture that could provide smooth and secure access to cloud applications (regardless of the location of the data/applications/users) was high.
As mentioned earlier SASE stands for: Secure Access Service Edge. But what is it exactly? SASE is a cloud-based network and security approach that ensures secure access to all your systems, data and (cloud) applications connecting all applications, users, data and resources (regardless of their location and regardless of the device used for access).
Various business locations are interconnected via a virtual network. Security has expanded beyond the previous perimeter of your corporate site. Control now operates at the edge of the cloud, rather than your organization’s data center. Signifying SASE’s transition of security from on-premises to the cloud.
On top of that, SASE is not a clearly defined security model. It is a way to structure your security landscape, allowing you to tailor your security solution perfectly to your business needs. It consolidates SD-WAN, Firewall-as-a-service, ZTNA, CASB and SWG functionalities into one unified cloud-native service.
SASE merges cloud security, zero-trust access and complete WAN provisioning. SASE services are applied based on the user’s identity and real-time context, offered by a SASE provider. Key characteristics of SASE include:
SASE represents a shift in network security paradigms. It offers a comprehensive, adaptable, and highly secure solution for the evolving demands of modern businesses. The integration of various security functionalities into a unified cloud-native service marks a significant step forward in ensuring safe and efficient connectivity in today’s dynamic digital landscape.
