Arbiter vs Arista Guardian for Network Identity (AGNI)

Arbiter is a cloud-hosted network access control product that determines which devices can connect and what they can access. It identifies and catalogs devices by type and vendor without endpoint agents. Access controls include certificate-based EAP-TLS and 802.1X, plus MAC authentication bypass for headless devices. Its on-premises Edge appliance connects over RadSec and can continue authenticating locally during a WAN outage using cached decisions. A live Microsoft Intune integration reads device compliance and can quarantine non-compliant devices to a remediation VLAN. SIEM event forwarding supports Microsoft Sentinel, Elastic, TLS syslog, Splunk HEC, and generic HTTPS webhooks. The service supports wired and wireless access control in a hybrid deployment. The Asset Discovery tier profiles and inventories devices but does not enforce access; the access-control plans include the full feature set and vary by endpoint count. Asset Discovery costs €29 a month after a 60-day free trial. Essential costs €149 a month for 100 endpoints, Professional costs €399 a month for 500 endpoints, and Enterprise costs €999 a month for 1,500 endpoints. Arbiter is designed for SMEs and the MSPs or MSSPs that support them.
