Arista says it helps organizations onboard users and devices, manage certificates, discover and profile connected devices, and apply identity-informed security policies. Those are vendor-described capabilities; the available sources do not establish independent performance results or comparisons with other NAC products.
What Arista AGNI does
Arista announced AGNI on April 24, 2023, as a CloudVision-based network identity service for enterprise security and IT operations. The service is intended to connect information about users and devices with decisions about how they access a network. Arista describes it as supporting standards-based wired and wireless networks. Arista’s launch announcement and its current product page are the primary sources for those claims.
In practical terms, a NAC service can help an organization identify a connecting user or device, determine whether it meets access requirements, and apply a policy to its network access. AGNI’s stated feature set spans that process, from onboarding and device visibility through authorization and enforcement. The sources describe capabilities, not a guaranteed result for every network configuration.
How AGNI’s stated capabilities fit together
Onboarding and authentication
Arista says AGNI supports wireless self-service onboarding using unique per-user pre-shared keys and 802.1X digital certificates. These are described as ways to securely bring users and devices onto a network; the exact workflow and supported configurations should be confirmed for the organization’s environment.

Certificate management
The launch announcement describes certificate management through a cloud-native public key infrastructure (PKI). Arista’s current product page summarizes this as certificate lifecycle management. Organizations evaluating the service should check the certificate issuance, renewal, and integration details they need rather than assume that every existing PKI workflow is supported.
Device visibility and profiling
Arista lists enterprise-wide device discovery and profiling, behavioral profiling, and visibility into connected devices. These capabilities are intended to give administrators context about what is connected before setting or changing access policies. The sources do not quantify discovery accuracy or coverage.

Authorization, policy enforcement, and segmentation
Arista describes security policy enforcement and authorization based on network identity and device context. It also describes micro-segmentation when AGNI is combined with Arista networking platforms and specified techniques; that qualification matters, and the claim should not be read as a standalone segmentation guarantee across arbitrary equipment.
What SaaS delivery means for an enterprise buyer
AGNI is presented as a cloud service rather than a physical retail product. Arista’s software licensing framework describes it as a term-based software subscription that includes software and support. The reviewed materials do not state current pricing, contract minimums, or trial availability; organizations should confirm commercial terms with Arista or an authorized channel partner. Arista’s Software License Framework provides the subscription context.

- 【DPI protection】Deep Packet Inspection with visual dashboards blocks adult/gambling/malicious sites, while SQM and QoS prioritize gaming, calls, and video when bandwidth is tight
- 【OpenWrt & USB 3.0 Expansion】OpenWrt with 1GB DDR4 and 8GB eMMC lets you install plugins and build VPN, ad-blocking or NAS, while USB 3.0 Type‑C connects high-speed storage or 4G/5G dongles
Cloud delivery may be relevant to teams weighing a hosted service against an on-premises NAC deployment, but “SaaS” alone does not establish which components remain in a customer environment, what data is processed where, or what integrations are available. Before procurement, validate the deployment boundaries and technical fit for the specific network.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.What the published evidence does—and does not—show
Network World’s April 24, 2023 coverage reported that AGNI used network telemetry and CloudVision information to evaluate and implement security policies. The article quoted Arista executive Pramod Badjate discussing onboarding, authentication, segmentation, and troubleshooting; this is attributed vendor commentary, not an independent product benchmark. Network World’s coverage provides the contemporary report.

Arista’s announcement also includes a customer testimonial from Aaron Miri, identified as CIO of Baptist Healthcare, about securely onboarding devices and integration with Medigate by Claroty for device profiling. It is a vendor-published testimonial, not a controlled study. The reviewed sources provide no named performance statistic, quantified deployment outcome, or balanced comparison with competing NAC platforms.
What to verify before evaluating AGNI
Because the public descriptions do not settle every compatibility or deployment question, an enterprise evaluation should test the product against its own requirements. Ask Arista or its channel partner to confirm:
- Which identity stores and authentication methods are supported, including any required integrations.
- Which wired and wireless network equipment and configurations are supported.
- How certificate issuance and lifecycle management fit with existing PKI processes.
- How device discovery and profiling work for the organization’s endpoint and IoT-device mix.
- Which systems enforce authorization or segmentation policies, and whether those functions require Arista networking platforms or specified techniques.
- What telemetry, operational visibility, and troubleshooting workflows administrators receive.
- What the cloud deployment boundaries, subscription term, support coverage, and total commercial terms are.
These checks also provide a sound basis for comparisons with other NAC options: compare deployment model, supported networks, identity and certificate integrations, profiling, enforcement, operational tooling, and licensing on the same requirements—not on feature labels alone.
