SASE: The future framework for network security

Modern workplace strategies are one of the driving forces behind digital transformation as enterprises work towards enabling their employees to work remotely and take advantage of the benefits provided by cloud serviceThis digital transformation is seeing an increasing amount of application and data moving outside of the traditional network perimeter.   

This new perimeter-less environment is changing the security landscapes for businesses, and there is a growing need for security and networking to converge to overcome the ever-increasing cybersecurity threats 

Secure Access Service Edge (SASE) framework supports the dynamic, secure access needs of digital enterprises by combining comprehensive WAN and networking security capabilities. SASE will demand that security and network teams collaborate. 

The cloud-native framework works towards optimising business and user experience by overcoming complexity, cost, performance, availability and protection. SASE has been identified to be a digital business enabler through speed, agility, and availability. 

 

The cloud-native security architecture unifies the landscape of network and security technologies: 

  • Network as a Service (NaaS) 
  • Software-Defined WAN (SD-WAN) 
  • Content Delivery Network (CDN) 
  • WAN Optimisation 
  • Bandwidth Aggregators
  • Cloud Access Security Broker (CASB)
  • Virtual Private Network (VPN)
  • Web API Protection as a Service (WAAPaaS)
  • Firewall as a Service (FWaaS)
  • Remote Browser Isolation (RBI)
  • Next-Generation Secure Web Gateway (NG SWG)
  • Data Loss Prevention (DLP)
  • Advanced Threat Protection (ATP)
  • Zero Trust Network Access (ZTNA)
  • Quality of Service (QoS)

Benefits of SASE: 

  • Enhanced flexibility through direct access to the network and the cloud outside of the traditional data perimeters. 
  • Cost savings as enterprises consolidate vendors and technology stacks. An increase in solutions on the market will also provide an opportunity for additional cost reductions.  
  • Enables zero trust by providing seamless and consistent protection of the entity's session on and off the enterprise's network. Policies are to be based on identity, not IP addresses providing end-to-end encryption. 
  • Improved protection against cyber-attacks including phishing, malware, ransomware and malicious insiders.  
  • Reduced complexity by having network as a Service from one vendor.  
  • Increased performance through latency-optimised routing 

Future of SASE 

The SASE framework provides an architecture for enterprises to securely allows users access to data and applications from any location 

There is currently only a handful of vendors providing comprehensive SASE solutions; however, this is predicted to increase as demand continues to be driven by digital transformation.   

The current adoption rate of SASE is below 1%. This percentage is predicted to increase over the next three years as the opportunity for security and risk management leaders to simplify their network security architectures grows.  

Gartner has estimated that 40% of enterprises will have an adoption strategy for SASE by 2024.
