Defeat Lateral Threats

For Security AdminsFor Network Architects

Build a resilient Zero Trust fabric where the network itself enforces policy at wire speed. Stop trying to bolt on more boxes — empower the switches you already deploy.

The Erosion of the Perimeter

Lateral movement is the breach

The "M&M" model — hardened shell, soft interior — is an architectural relic. Once an attacker is in, the absence of internal controls is what turns a foothold into a ransomware outbreak. Stacking internal firewalls becomes a performance choke point that kills modern NVMe and AI throughput; agent-based approaches ignore the printers, sensors, and legacy medical or industrial gear that can't host third-party software in the first place.

Security at Wire-Speed

MSS offloads enforcement to the ASIC

Multi-domain Segmentation Services moves micro-perimeter enforcement out of dedicated appliances and onto the switch silicon you already operate.

No endpoint agents required

Security is enforced at the network entry point — covering 100% of the environment, including the blind spots agent-based models leave.

Unmanaged device coverage

IoT, OT, legacy medical, industrial control — the gear that can't host an agent gets segmented anyway. Often the weakest links, finally protected.

Native network integration

No "hair-pinning" of east-west traffic to a central firewall. Enforcement happens inline at the first hop — no detour, no efficiency loss.

No proprietary overlay

No special protocols. No expensive hardware overlays. Wire-speed enforcement on standard EOS — the operational model you already know.
The Unified Architecture

Segmentation, identity, and detection — together

A complete Zero Trust posture needs a "where," a "who," and a "how." MSS handles segmentation; Arista Guardian for Network Identity (AGNI) verifies users and devices regardless of entry point; Arista NDR applies AI-driven threat hunting to catch sophisticated actors who slip past initial defenses. Three layers, one fabric, line-rate enforcement throughout.

EOS State Sharing

Stateful Fault Containment ends the 3 AM reboot

Modular Linux-based OS where every process runs in protected memory and exchanges state via Sysdb — no bundled "monolith failure" anymore.

Process isolation

A failed process can't take the system down with it. It restarts independently and resyncs from Sysdb — no cascading failure across the fabric.

Live patching

Apply security fixes to individual processes without a system reboot. Maintenance windows shrink; surface area to vulnerabilities shrinks faster.

ZTP at scale

Zero Touch Provisioning + CloudVision turns deployment from manual configuration into a self-healing automation pipeline — at any site count.
