Remote Worker Numbers Skyrocket due to COVID-19 – Is it Time to Move Up to SASE and Away from VPNs and Traditional SD-WAN?


MARCH 2020

By: Chris Swan

Cyberthreats are growing exponentially during the COVID-19 global pandemic. As the CDC recommends keeping citizens at home, governments are issuing guidance and even legislating remote working for those employees who can be productive from home. We are fortunate to have amazing residential broadband networks to support the growing volume of video calls, remote learning, document sharing and other collaborative business tools to keep employees productive.

Remote Internet security should be fundamental but is often administered with VPNs and frequently abandoned due to user frustrations with speed, complexity and performance. Increasing amounts of personal and professional data are now traversing public networks. But the level of risk is growing across a wider plane of mobile devices, access technologies and an even more distributed workforce during this crisis.

Securing all that data traveling over residential public internet connections is a big problem worth solving. VPN (Virtual Private Network) technology has been a solution of choice for many businesses over the last two decades, along with private MPLS, but today more companies are moving to SD-WAN to connect distributed offices and the employees in them. While there are distinct benefits associated with traditional SD-WAN, the vast majority of these solutions still rely on the same problematic VPN and MPLS architectures and technology.

We believe the next generation of secure networking, defined by Gartner as Secure Access Service Edge, or SASE (pronounced “sassy”), will become the standard for solving these challenges. Dispersive has embraced the concepts of SASE since our inception. Our initial design focused on the convergence of WAN (wide area networking) and Network Security into a single, cloud-delivered service model. 

Instead of managing network and security separately, SASE simplifies and unites these efforts. So, with SASE, Enterprise IT leaders can now solve for scale, security, flexibility, performance and cost containment under a single integrated approach while they simultaneously manage the explosion of data, computing, remote workers, branch offices, applications, collaboration tools, IoT systems and edge computing entities.

Let’s look at this in the context of WFH (Working from Home).

Traditional point-to-point networking and security architectures are cumbersome, complex and costly to own and operate for enterprises and government agencies.

Standard networking and security solutions struggle to fully support today’s cloud-centric and mobile-first digital enterprises.

These networks are static and inflexible, with security often siloed across multiple domains. Traditional solutions do not scale and slow down the business instead of enabling innovation and agility, and this challenge is exacerbated as more – substantially more – employees connect in from their home offices.

Unified networking and security under a cloud-native framework enables simplicity, agility, and lower costs.

A SASE platform delivered over a distributed cloud framework provides security features for all endpoints, users, and edges.

Dispersive’s SASE solution enables enterprises to manage network and security policies through a single console, making it easier and more efficient for IT teams and managed service providers to orchestrate, manage, and troubleshoot, no matter where they are.

Here are seven reasons why it is time for organizations with distributed workers to benefit from moving up to the next generation of ultra-secure and high-performance network technologies:

  1. Zero Trust: Complete protection down to segment, IP address, port and protocol.
  2. Increased Performance: SASE cloud architectures have built in WAN Optimization capabilities to boost performance across even the toughest connections.
  3. Reduced Complexity: An integrated network security stack model reduces the number of layered security products an IT team must manage, update and maintain.
  4. Greater Scalability and Flexibility: SASE enable enterprises to easily deploy, integrate, and manage new endpoints, apps, and services in an efficient and secure framework.
  5. Data Protection: SASE data protection policies prevent unauthorized access and misuse of proprietary data and the network.
  6. Reduced Cost: SASE converts need to buy and manage multiple point appliances into a single virtualized platform dramatically reducing costs and IT resources.
  7. Enables Faster Innovation: SASE frameworks streamline new product development cycles, making companies more responsive and reactive to market needs, business opportunities and the competition.
