In the post-COVID-19 world, hybrid and remote work have become the norm among organisations in the Asia Pacific region. Companies now use scores of SaaS applications and internal file-sharing systems that are accessed by employees who are working outside the office.
VPNs and centrally applied security policies present choke points in traffic flow, forcing organisations to invest in larger and costlier security solutions and products. Meanwhile, the network perimeter has become amorphous and the potential attack surface unclear.
As the network perimeter expands, organisations are using software to define it. The key question is: How can you leverage the advantages of a software-defined wide area network (SD-WAN) while enforcing a consistent security policy when your employees are working from anywhere?
This is where Secure Access Service Edge (SASE) comes to the rescue of APAC enterprises that are either still in the infancy of adopting SD-WAN or starting to look for a better approach in securing their WAN.
SASE is a framework rather than a technology. It represents the convergence of several established technologies that merge SD-WAN capabilities and network security functions into a unified approach.
SASE comprises five security and networking technologies:
- Firewall as a Service (FWaaS)
- Cloud Access Security Broker (CASB)
- Secure Web Gateway
- Zero Trust Network Access (ZTNA)
The framework is designed to ensure that the applications and data that workers need to stay productive would remain optimised for performance, are always available, and are protected wherever they are accessed from. SASE distributes all checkpoints across various regions to improve the efficiency of network resources, and reduce the latency created by the hub-and-spoke model.
The advantage of SASE is that it is designed with the user in mind and begins with the idea of zero trust. To make things simple for you, here are five signs that proves your organisation can greatly benefit from SASE today:
