Secure Access Service Edge—the security model for today’s remote work environment

March 03, 2021

Secure Access Service Edge—the security model for today’s remote work environment
With so many businesses working remotely right now—and many now considering the adoption of a long-term work-from-home strategy—the Secure Access Service Edge (SASE) model is gaining traction. This model, originally put forth by Gartner, allows any endpoint to access any application over any network in a protected manner.

An SASE architecture identifies users and devices, then applies policy-based security and delivers secure access to the appropriate application or data. This allows organizations to apply secure access wherever their users, applications or devices are located.

SASE services are cloud-native and globally accessible and offer multiple capabilities including:

  • SD-WAN
  • Secure web gateways
  • Cloud access security broker (CASB), an on-premises or cloud-based security policy enforcement point that combines and interjects enterprise security policies as cloud-based resources are accessed
  • Next-generation firewall
  • Zero trust network access, which ensures secure access to applications without giving users access to the enterprise network
 
The benefits of an SASE security model

  • Flexibility – Companies can implement and deliver security services such as threat prevention, web filtering, sandboxing, DNS security, credential theft prevention, data loss prevention and next-generation firewall policies to all of their remote users.
  • Cost savings – Utilizing a single platform eliminates the need to buy and manage multiple point products, dramatically reducing costs and IT resources.
  • Simpler IT infrastructure – Consolidating a company’s security stack into a cloud-based network security model reduces the number of security products IT teams have to manage.
  • Greater performance – With a cloud infrastructure, users can easily connect to wherever resources are located. Access to apps, the internet and corporate data is available globally.
  • Zero trust – An SASE solution provides complete session protection, regardless of whether users are on or off the corporate network.
  • Threat prevention – With complete content inspection integrated into an SASE solution, companies enjoy greater security and visibility into their networks.
  • Data protection – Data protection policies implemented within an SASE framework help prevent unauthorized access and abuse of sensitive data.
A model whose time is now
“Although SASE is relatively new, the COVID-19 pandemic has fostered the need for business continuity plans that include flexible, anywhere, anytime, secure remote access, at scale, even from untrusted devices,” explains Joe Skorupa, research vice president at Gartner. “Over the last three months, SASE has been adopted by more than 40% of global remote workers.”
Given the challenges of managing a remote workforce, the Secure Access Service Edge model  may be a smart option for your customers to consider. To learn more, email our security experts at cybersecurity@ingrammicro.com.
