SASE: The Next Evolution of Network Security in the Cloud
SASE: The Next Evolution of Network Security in the Cloud

With numerous modern threats to data security, from malware to phishing attacks, protecting your organization’s sensitive data has never been more important – or more challenging. Many existing network security systems are quickly becoming insufficient. Today’s workforce needs immediate, reliable, and secure access to the applications required to perform their jobs – both at the office and in remote locations.

Insight’s 2021 cybersecurity report indicated that 78% of IT executives lack confidence in their organization’s current IT security. The time has come for the adoption of more sophisticated tools and methods. 

SASE (Secure Access Service Edge) is ushering in the next generation of cybersecurity for networking in the cloud. First defined by Gartner in 2019, SASE is a cloud service model that combines WAN (Wide Area Networking) with advanced network security services. Secure access to data and applications is granted to approved users and devices in any location, in line with a company’s designated security policies.

What are the benefits of SASE?

There are many advantages to implementing a SASE solution for your business. Here are a few of the top reasons to consider making the transition:

  • Comprehensive security. Switching to SASE means increased visibility and security coverage. A SASE provider can quickly and easily roll out security updates in the cloud, and zero-trust networking is set up based on the user and device, not a location. Policies can be set centrally and enforced uniformly in all locations by distributed PoPs.
  • Improved access. With SASE, immediate access to your business applications is available to your workforce across the globe. Authentication procedures are simplified, creating a streamlined access model and increasing productivity. 
  • Greater flexibility. A custom SASE implementation allows you to select the exact security features you need to match your business requirements. Whether you need advanced firewalls, secure gateways, API protection, DNS security, zero-trust access, or more, SASE can be configured accordingly – and it scales easily too.
  • Cost savings. SASE is structured as a single unified cloud platform. WAN deployment with SASE is simplified, and fewer vendors are required to operate your network. You’ll save on hardware and software costs too.
  • Reduced maintenance. A SASE cloud solution means fewer devices to deploy and maintain. Your IT team will spend less time managing your network and be able to reallocate it toward other important priorities instead.

Choosing the right SASE solution

The emergent SASE market is still taking shape, with different vendors varying in what they offer. Here are several important considerations to keep in mind when selecting a SASE provider and solution for your organization:

  • Which features are most critical for your business? Make a list of the SASE features that are a top priority for you. The provider you partner with should offer all of the customizations you need and have many technology partners to support any necessary integrations.
  • Is the solution less complex? A unified cloud solution usually streamlines systems and processes and reduces reliance on hardware – but don’t take this for granted. Find out what it will take to implement and manage your new SASE solution and how it will fit your overall technology ecosystem.
  • How much cost savings can you expect? When evaluating a potential SASE solution, consider both the upfront costs of implementation and the long-term operational costs. Compare these costs to the savings you expect from reducing or retiring legacy systems. Also, assess how flexible consumption is and what scaling will look like.
  • Is the architecture fully integrated? A complete SASE solution provides both enterprise-class networking and best-in-class security services in a unified native cloud platform. It should secure all of your applications and data for your entire workforce across all locations. Anything less isn’t a trustworthy SASE platform.
  • Does the platform reside on solid cloud infrastructure? Not all clouds are created equal. Look for a cloud-native solution backed by a large number of well-connected data centers. Comprehensive coverage should be available for all network edges, including on-premise, cloud, and mobile access points.
