Work Securely, Anywhere, Anytime 

Secure Access Service Edge (SASE) is a new approach to networking and security, securing access to web, cloud, and private applications. Providing anywhere, anytime access from any device. 

SASE combines VPN and SD-WAN capabilities, with cloud-native security functions, such as secure web gateways, cloud access security brokers, firewalls, and zero-trust network access. Delivering a unified cloud-native service. 

Key Benefits

SASE creates a platform that connects all parts of the networking and security capabilities an enterprise requires. Some of the key benefits a SASE platform provides include:

Faster and more effective performance

Unleash your workforce by delivering a seamless connection to applications in any environment from any location.

Eliminate blind spots and gain control

Simplify security, streamline policies, and increase protection with a multifunction cloud security service.

Connect your enterprise to reduce costs

Unite security and networking through a flexible, integrated approach that meets multi-cloud demands at scale.

Three Minute Overview

What is SASE?

SASE combines network security functions with WAN capabilities (i.e. SD-WAN) to support organisations' dynamic secure access needs. Gavin Wood, CTO at Chess, provides an overview.

5 steps to SASE

SASE security must enable people to get their jobs done safely, not inhibit productivity. These anywhere workers need the freedom to work safely from any location at any time.

Each user should only have access to the resources they have explicit permission to use, under the full visibility and control of your business.

SASE must provide ongoing control of how critical data and intellectual property is used once downloaded from apps. This prevents data from inappropriately going to the cloud, web or personal accounts - unintentionally or maliciously.

Users at remote sites must have fast, secure access to web, cloud and private apps without the costs or complexities of private MPLS lines or backhauling traffic to HQ. Easy integration with SASE services is crucial for management at scale.

Controlling data usage, especially on remote devices and cloud services, requires an ongoing understanding of what people are doing and whether their behaviour is creating risks that could become breaches.

Key Questions 

If you're considering your requirement for SASE, ask yourself these key questions:

  1. How do remote workers access your cloud and private apps today?

  2. What did you have to change in your infrastructure or operations to support work-from-home (WFH)?

  3. What cloud applications does your organisation sanction today?

  4. Do you have visibility into unsanctioned applications that include data sharing capabilities?

  5. Do you have control over the cloud/internet security for your remote workers?

  6. Are you looking at ways to consolidate hardware at your network’s edge (in offices, branches, etc.)?

  7. What is your strategy for securing access to internal, private apps?

  8. What is your organisation’s exposure to risk for data being “lost” in the cloud, exposed publicly, or outright exfiltrated?
