What is SASE for network architecture?

Secure Access Service Edge (SASE) is a modern network architecture that abstracts network and security appliances and delivers them from the cloud edge. It securely connects users, systems, and devices to cloud applications anywhere in the world. It refers to the framework as a whole rather than a single technology.

SASE can be compared to a cloud-based cyber security service with WAN capabilities. This supports an enterprise's need for dynamic and secure access to networks and digital platforms. Security service edge (SSE), a subset of SASE that only focuses on cyber security services from a cloud platform, should not be confused with SASE.

SEACOM Business offers enterprises in Kenya both SASE and SSE network architectures. These modern solutions make use of zero-trust security principles to strengthen the security posture of an organisation, enhance user experience, increase network visibility, and simplify IT systems.

How does SASE work?

A SASE architecture is a purpose-built, cloud-native solution that secures users' access to the internet, cloud services, software as a service (SaaS) and private applications, regardless of location. In essence, SASE is the convergence of network and security appliances delivered from the cloud edge, allowing security to follow the user wherever they may be. This differs from traditional network architecture, which places security within the network of an organisation.

SASE is suitable for all types of businesses, especially businesses that employ the work-from-anywhere model. With legacy architectures, such as multiprotocol label switching (MPLS), remote traffic is sent through a firewall, to a data centre and then routed back. As a result, there are delays, reduced productivity, and an inferior user experience.

All traffic is inspected at a nearby point of presence before being sent directly to the destination with SASE, which is secure and direct. This improves efficiency and cuts down on network delays. SASE does a far better job of protecting users all the way down to the end-point.

SASE architecture for enterprises

The core challenges with mobile work, the cloud, security and digital transformation are addressed by SASE. Company data begins to reside outside the confines of on-premises data centres as more companies adopt software, infrastructure as a service (IaaS) and other cloud-delivered applications. Partnered with this, the number of remote and mobile users is increasing, connecting from anywhere, over any connection to their data and cloud apps.

SASE is highly scalable and can expand along with the business because it is cloud-based. The service can be expanded to provide the highest quality performance, reliability, security, and connectivity as networking requirements grow. It is perfect for a world where mobile devices are the primary means of network traffic and access for an increasing number of remote workers.

The fundamental needs of enterprises and their cyber security challenges can no longer be met by legacy network architectures as apps move to the cloud and Internet of Things (IoT) devices become ubiquitous. SASE meets modern requirements for cloud networking and security while reducing network complexity and costs.

SASE decreases the likelihood of emerging cyber threats, enhances user experience, and boosts business productivity. For more information or to get a quote for our SASE networking architecture services, email us at marketing@seacom.com or leave us a message.
