What is SASE and why should you care?

What is SASE and why should you care?

We'll cut to the chase: traditional network architectures are no longer efficient or secure.

Why? Because in this modern age, businesses don't just rely on immediate network access from a single office; they need greater flexibility.

With the adoption of cloud-based applications and remote working initiatives, less and less traffic is directing back to data centres. Instead, there's a heavier reliance on disparate offices and cloud services.

Which begs the question: what does a modern network architecture look like?

That's where SASE (Secure Access Service Edge) comes in.

New call-to-action

What is SASE?

That's a brilliant question. Here's our brief definition:

SASE combines WAN (wide area networking and network security into one cloud service model. This service adapts to your business's unique identity access needs, data and security policies, locations and devices to keep your employees connected and secure.


In short: it's a modern network solution for modern businesses.

But what are the specific advantages of this new network trend, and why should it matter to your business?

The case for SASE in your business

The inconsistent and poor connectivity that comes with legacy network infrastructures can hamper your business's productivity.

Fortunately, a SASE infrastructure will reduce latency and increase the reliability and security of your networks. Specifically, your business will benefit from:

  • Reduced costs. A traditional network requires multiple physical products for multiple locations. A SASE solution only requires one central portal, which will not only save you money, but will also save your IT team the hassle of setting up and managing networks, too.
  • Remote-ready, secure network access. SASE's identity-centric architecture allows for immediate access to your network, no matter whether your employees are in a branch office or sat in their home. A SASE solution also secures each individual simply by enabling security at the point of internet exchanges and connections.
  • Limited security risks. Remote working is the new norm; you can either prepare for it, or face the security consequences. Thankfully, SASE is built with remote security challenges in mind. The solution inspects each connection and runs on a ZTNA (zero trust network access) model, which ultimately only provides access to authorised individuals (based on business policies).
  • Improved user experience and performance. Whether you're looking to introduce flexible working initiatives or set up new branch offices in a different location, a SASE-driven network can accommodate any network access seamlessly and with little latency.

Embrace the new network norm

By 2024, Gartner predicts at least 40 percent of enterprises will adopt SASE.

That's hardly surprising.

Chaining your network architecture to a single data centre is inflexible at best. It goes against the needs of your business and the changing tide of modern technology.

To keep your company protected, productive and agile, you'll need to venture into a more secure, cloud-based network solution. And we think SASE is a great option.
