The private network, the network perimeter, the enterprise network… For network operators and cybersecurity officers these can now represent obfuscated views and oxymorons. Arguably, there is no enterprise network anymore.

Users are demanding a more seamless experience as IT services have moved out to the cloud, and perimeter security isn’t working – attackers have repeatedly demonstrated that they can get in behind firewalls and spread laterally within enterprise networks. The COVID-19 crisis has accelerated these trends. With many organizations asking their employees to work from home for what may be an extended period of time, the perimeter as a construct is effectively gone.

A different approach is needed, one which brings security where the traffic is rather than backhauling traffic across the Internet to a firewall to inspect it.

Zero Trust Architecture Deployed at the Network Edge

A Zero Trust Architecture (ZTA) is one in which granular access controls allow subjects (users, IoT devices, bots, microservice processes) to reach the resources they require without also allowing everything within an internal network to access everything else by default. Zero Trust is an ideal security objective, but the challenge with achieving it has always been the complexity of implementing granular controls.

The Secure Access Service Edge (SASE) Expands Connectivity, QoE, and Network Security

These management and user experience challenges are being addressed by delivering security capabilities from the Internet as a service with a unified management platform that cuts through unnecessary administrative overhead. Gartner has dubbed this architecture the Secure Access Service Edge, or SASE, pronounced “Sassy.” SASE provides us with the agility to rapidly deliver security capabilities when and where they are needed without compromising on effectiveness.

You need a roadmap for achieving a Zero Trust Architecture with a seamless user experience through the use of SASE capabilities. The resulting infrastructure reduces end user frustration with VPNs while improving an organization’s security posture and enabling the business to move faster.

The Zero Trust Secure Access Service Edge

Read the white paper to understand how you can prepare for the secure access provisioning challenges the cloud and direct Internet bring.

  1. Orchestrate security policy for distributed network access without the pains and costs of backhauling traffic and compromising user experience.
  2. Demystify the dark quandary between internal and external networks, and instead, secure channels that can provide access to resources while validating each request in the same way regardless of what network it originated on. SASE is network and security policy extended out to the very edge of your network access infrastructure.
  3. Secure each connection as access is sought. Provide high-performance zero trust network access at or near the point of connection, instead of backhauling or tolling the closest firewall appliance. SASE simply embodies what you’re accustomed to with firewall and VPN service, only security is always on wherever access is sought.
  4. Trust no one, validate out at the point of access, leveraging fast-response security proxies and safeguards from the cloud.
  5. Protect against lateral infection. It’s more than just network access control; it’s making sure workstations and workloads don’t contaminate each other with malware and social engineering ploys. Protect your network traffic patterns, too, through segmentation to avoid risk, and extensive data, reputational, and financial loss damage.

Learn more about the Secure Access Service Edge (SASE), which focuses network and security service management through software intelligence and fosters and facilitates constructive NetOps and SecOps/ZTA service management.
