SASE for Beginners: All you Need to Know

Secure Access Service Edge (SASE), pronounced “Sassy”, was Gartner’s response to the enterprise security havoc of 2019 when Americans were forced to relocate offline for the remainder of the pandemic. In contrast to the beginning days of the Internet, businesses have more data, devices, applications and services stored in different clouds and away from their enterprise network than on it. This could affect enterprise security and effectiveness.

So, what is SASE? In simple words, SASE is the model that attempts convergence – where all this data , devices and applications converges in one secure spot. Put another way, SASE connects network as a system with network as a secure system for guaranteed data confidentiality and integrity. It does this by functioning as a single entity that delivers the security stack outside the traditional perimeter.


SASE is the new frontier in cybersecurity. Year-on-year, the number of work-from-home employees grows along with an increasing number of devices, different applications and swelled data. Consider Workplace by Facebook, AWS, OKTA, Salesforce, Splunk, Yahoo, Gmail and Google Cloud for starters. our networks have evolved into siloed structures: SaaS, PaaS and IaaS that just makes complexity seem bottomless and leads to unreliable and unsecure delivery.

In short, our user system is highly distributed and our network of services is also highly distributed, both crossing multiple geographic areas. That makes it frustrating for businesses to provide their promised confidentiality and integrity of data and business services.

A SASE service helps by bundling the business network with security and converging it on one central core that’s used by users anywhere, regardless of location.

SASE user-case: an example

Sarah, a sales executive, uses her company’s laptop at Starbucks, browsing its CRM system through the restaurant’s WiFi. A select SASE system would protect her company from possible invaders. Sarah could enter through clientless access or through a special SASE client to establish a tunnel to the SASE platform. Either way, the platform’s sophisticated security tools would protect the business from attack and keep its data secure.

SASE: Network as a system

SASE mediates distributed users and distributed cloud services and provides all the network controls and network services of regular cloud providers.

Network attributes include:

  • Latency optimization – keeping the network frictionless and fast. Similar toSaaS Acceleration of end-to-end acceleration and performance of SaaS applications.
  • Quality of service
  • Geo restrictions (or geo blocks) where providers make their websites available only in certain countries.
  • Routing and path selection – selecting a path for traffic in a network or between or across multiple networks
  • Caching – storing frequently requested content.
  • Content delivery network (CDN) – the geographically distributed network of proxy servers and their data centers.
  • Traffic shaping – the bandwidth management technique that regulates diagrams across different devices, functions and services
  • Data deduplication – eliminating duplicate or redundant data in computer storage

The SASE security platform ensures that users, regardless of location, can connect to your services faster and more reliably without having to bounce back through the private corporate internet, VPN  or public internet.
Now that we have the enterprise service on one spot, we need to protect its assets and users. This is where SaaS bundles the enterprise network with the latest in security controls.

  • Data loss prevention (DLP) tools
  • API protection as a service (WAAPaaS)
  • Cloud threat protection
  • Firewall as a service (FWaaS) – Cloud firewall with advanced protection.
  • Zero trust network access for maximum security
  • DNS & WiFiprotection
  • User and entity behavior analytics (UEBA)
  • Network encryption tools
  • Remote browser isolation with malware and antivirus protection

This secured network stores items like compliance checks, backup insurance, VPNs, user backup wallets, and filter controls.


The benefits of this intuitive system are immense. These include:

  • Reduction in complexity and costs – SASE prevents users from paying for multiple apps. There’s also low operational overhead, in that there’s a single entity with a single monitor console
  • SASE enables new digital business scenarios by ensuring that the bruins uses the newest and most secure business applications available
  • Improvement in performance and latency because the network communicates on one pane of glass – which also makes it easy to use and transparent.
  • Improved security by leveraging the ability of Next Gen gateways. SASE also enables zero trust network access, giving allowing only right users the right access to the right product applications
  • Centralized policy with local enforcement. There’s a  single place for all your network and security  controls.

SASE also increases the effectiveness of your network and security staff in that they don’t have to learn multiple different products on different platforms. SASE, in short, is centralized and functionable.

Top companies that are developing SASE in 2021

MVisionUnified Cloud Edge

A renowned SASE provider. US-based McAfeee MVision Cloud is the only vendor to be awarded all three Gartner Peer Insights Customers’ Choice Awards for CASB, Secure Web Gateway, and Data Loss Prevention. McAfee was the first cloud-based product stack that provides security across devices, networks, clouds (IaaS, PaaS, and SaaS).


US- based Twingate is a secure remote access solution (or SASE) for an organization’s private applications, data, and environments. It surpasses competitors in its ease of use, quality of support and ease of setup.

Cato Networks

Cato Networks is an Israel-based enterprise networking and security company. The company integrates edge SD-WAN, global private backbone, and cloud-security services for security across enterprise locations, cloud infrastructure and users.


SASE is the future of network security in an age when protecting our data assets becomes ever more difficult and fraught with attacks from accelerating data, users, devices, services and applications. The rise of SASE has been swift. Gartner predicts that at least 40 percent of enterprises will adopt SASE by 2024, enabling industries across sectors and locations to protect their high-value data.
