SASE Architecture: Why It Matters in Modern Networking

SASE Architecture

“SASE can help to improve both your network speed and your security at the same time”. Yes, you heard it right. With SASE, organizations have reported faster networks and stronger security. 

The traditional ‘fast vs safe’ comparisons are now invalid. If you still haven’t found it trustworthy, look at the Fortinet reports: “61% of the organizations reported improved security and 65% reported enhanced network after adopting SASE.

Earlier, the corporate data centre was the only guardian. But in the world of remote work, SASE (Secure Access Service Edge) has become popular for its seamless systems. 

Read on to understand how SASE architecture unites security and network into one seamless system – built for speed, scalability and security. 

What is SASE Architecture and How Does It Work?

SASE(Secure Access Service Edge) is a cloud delivered framework that provides both security and networking in a single service. It routes user traffic to the nearest SASE PoP (point of presence), where tools like firewalls and malware filters are applied at the same time. 

It doesn’t force data through any central data centre. But secures it at the edge – closer to users. The result?

Faster connections, stronger protection and simplified management across offices and remote teams. 

Understand it as a smart checkpoint system that travels with your data wherever it goes.  

What are the Core Components of a SASE Framework?

The SASE framework is based on five key pillars:

  • SD-WAN (software defined wide area network): optimizes routes.
  • SWG (secure web gateway): filters malicious sites.
  • CASB (cloud access security broker): secures SAAS usage.  
  • ZTNA (zero trust network access): verifies every device. 
  • FWaaS (firewall-as-a-service): delivers enterprise-grade protection without hardware.

Fun Fact
Over 80% of the enterprises use at least two of these services in a cloud model – and most of them don’t realize they are already halfway to SASE. 

How does SASE Architecture Improve Enterprise Security?

“SASE operates on Zero Trust – which verifies every connection and trusts no one” 

Every connection is verified based on identity, device and context – whether it is a user from the office, at home or on public wifi. 

Like airport security, it rechecks every passenger at every terminal – even frequent flyers. 

The result? Stronger security with zero attacks. 

According to Gartner, around 63% of organizations either fully or partially implement a zero trust strategy.

What Role Does Networking Play in a SASE Solution?

Networking (SD-WAN) makes SASE possible. It is also termed as the networking backbone.

SD-WAN routes traffic to the nearest SASE PoP (point of presence) – ensuring the user gets minimal delay and maximum uptime. 

It is like an online food delivery service that routes each order to the nearest kitchen. SD-WAN does the same for your data. 

Its design makes it flexible – if one Pop fails, another one is rerouted automatically.

How is SASE Different from Traditional Network Security Models?

Let’s explore the comparison between SASE and traditional security architectures.

  • Old systems built higher castle walls. SASE replaces them with guards that move with you. 
  • Traditional systems rely on physical hardware like firewalls and VPNs. SASE replaces them with a cloud-first and identity driven approach. (Works best for hybrid models too)

No matter where the data goes – AWS or Google Cloud – it’s safe with policies of SASE.

What are the Key Benefits of a SASE Solution?

The key benefits of SASE include:

  • Single management system: One engine for users, data and apps. 
  • High speed performance: Reduced delays with PoP.
  • Stronger security: The zero trust model verifies every connection.
  • Cost efficient: Eliminate redundant hardware dependency.

The impact isn’t just theoretical  – after using SASE,  Aryaka found 113% ROI and around US $2.48 NPV over a 3-year model. 

What Challenges Should You Expect When Adopting SASE?

Along with plenty of benefits, SASE has some challenges too:

  • Integration pain: Systems don’t always merge easily.
  • Vendor Issues: Some providers provide partial SASE services. 
  • Skilled manpower: Managing SASE requires some expertise.  

Good news? These hurdles get away with time and experience. Early adopters like Aryaka are already enjoying tangible returns. 

Which Scenarios Is SASE Architecture Most Useful for?

SASE is a game changer for:

  • Remote-first organizations requiring secure access from anywhere. 
  • Multicloud environments integrated with AWS, Azure and more.
  • Enterprises with local branches requiring policy enforcement.

For these, SASE is “the Netflix of networking” – scalable, on-demand and customized for user needs. 

“According to a report hosted on Amazon AWS – SASE is still in its early stages and may take around 5 to 10 years to become mainstream”.

It is better to switch to SASE now – before everyone else does. 

SASE isn’t just the future – it’s a smart move today. The sooner businesses adopt it, the quicker they turn complexity into control and risk into security. 

FAQ

Why should I switch to SASE now?

The more you wait, the more it will be to untangle traditional systems.

Is SASE expensive?

Not really, even though it helps to reduce various operational and other costs.

Can my small business also use it?

Yes, it can provide the same cloud protection to small businesses too.
