Arista Networks Unveils Zero Trust Networking Vision

With the goal of revolutionizing cybersecurity, renowned cloud networking solutions vendor Arista Networks has launched an unprecedented zero-trust networking architecture. This all-inclusive strategy leverages the network architecture to break down security barriers, optimize workflows, and enable a cohesive zero-trust program.

How is Arista Network’s Zero-Trust Networking Securing the Modern Enterprise?

Enterprise networks of today span a variety of contexts, from cloud infrastructure and IoT to traditional campuses and data centers. The United States Cybersecurity and Infrastructure Security Agency (CISA) has implemented a Zero Trust Maturity Model in recognition of the necessity for a strong defensive mechanism. Five fundamental pillars are covered by this model’s prescriptive guidance: identity, devices, networks, applications and workloads, and data.

Arista’s Zero Trust Architecture Building Blocks

Through seamless integration with pre-existing security technologies, Arista Network’s zero-trust networking architecture leverages the underlying network infrastructure, from switches to WAN routers, to offer critical security features. Important elements of this comprehensive security system are of:

  1. CloudVision AGNI: simplifies posture analysis, network access management, and secure onboarding and troubleshooting for users and devices.
  2. Macro Segmentation Service (MSS): makes it possible to use edge switches to create and enforce microperimeters that safeguard or isolate individual assets without the need for a large-scale firewall deployment.
  3. Network Detection and Response (NDR): identifies, categorizes, and automatically finds devices, users, and apps. It also detects and handles threats on a dispersed network.
  4. Encryption Support: enables native support for encryption features like MACsec and Tunnelsec, protecting data going to and from older apps without changing the system.

A shared management plane (CloudVision) and unified operating system (EOS) are essential components of Arista’s zero-trust architecture. In order to support forensics, analytics, and threat hunting, the EOS Network Data Lake (NetDL) acts as a single source of network data “truth.” By utilizing AI and machine learning technology, Autonomous Virtual Assist (AVA) lessens operational burdens through improved visibility, continuous threat identification, and access control.

Extending the Ecosystem with Zscaler

With its open and API-friendly architecture, Arista’s zero-trust architecture removes blind spots and streamlines operations among security pillars. Zscaler, Microsoft, and CrowdStrike are among the newest strategic partners. Arista NDR is improved by the connection with Zscaler’s Zero Trust Exchange platform, which provides vital information about attacker infrastructure and domains. Zscaler Internet Access (ZIA) will be able to prevent access from hacked devices or malicious domains or IP addresses that have been recognized thanks to this agreement.

Embracing Zero Trust in a Changing Landscape

The increasing popularity of cloud computing and changing perimeters make traditional security methods ineffective. The zero trust policy of Arista becomes crucial for guaranteeing the safety of users and resources. Zscaler’s Vice President of Business Development and Technology Alliances, Amit Raikar, highlights that clients of Arista and Zscaler together have more control over risk and policy enforcement for their whole workforce, which strengthens their businesses in the end.


Through the utilization of Arista’s zero-trust networking architecture, enterprises can now effectively dismantle security silos, optimize processes, and include a resilient zero-trust initiative. An important turning point in the field of network security has been reached with Arista Networks’ announcement of an enhanced zero-trust networking architecture. Arista seeks to solve the changing difficulties in establishing zero trust controls by utilizing the underlying network architecture and strategic alliances, offering businesses a complete and efficient security solution for their dispersed and dynamic networks.
