Understand Secure SD-LAN before you buy it
Most product pages skip this. We start here — so you buy a capability, not a buzzword.
What is Secure SD-LAN?
Secure SD-LAN brings zero trust and IoT security natively to the campus and branch LAN — the switch port. Full security inspection runs AT the access switch, and compromised devices are microsegmented in real time.
It runs the same VOS™ as Versa's SD-WAN and SSE — one OS, one console, one policy from port to cloud.
Flat, trusted LAN vs Versa Secure SD-LAN — the honest table
What changes when security moves to the switch port, dimension by dimension.
| Dimension | Flat, implicitly trusted LAN | Versa Secure SD-LAN |
|---|---|---|
| LAN trust model | Flat, implicit — plug in, you're on | Zero trust at the switch port |
| Where security runs | Backhauled to a central firewall | At the access switch, closest to the host |
| Lateral movement | Happens before inspection sees it | Contained by real-time microsegmentation |
| IoT / OT devices | Unmanaged blind spot | Discovered and protected natively |
| The stack | Switch + firewall + NAC, separate | One converged VOS™ box |
| Policy | A different tool per layer | One language, port to cloud |
| Visibility | Campus LAN is a black hole | Every device and flow, one lake |
| Zero trust reach | Users and WAN only | Users, WAN AND the campus LAN |
Migration is phased — sites move over as access-switch refresh cycles land, pilot site first.
The five pieces of the platform
Vendors love diagrams; buyers need to know what they’re actually operating. Here’s Versa Secure SD-LAN, demystified.
Versa Switches & APs
Ethernet switches and access points running VOS™ — switching, routing, security and services converged in one box, so inspection happens at the very port a device plugs into.
VOS™ at the Edge
The single-pass OS behind Versa’s SD-WAN and SSE now runs at the LAN edge, so IPS, malware, CASB, DLP and UTM inspection happens at the switch.
VersaAI UEBA
Assesses user and device behaviour and posture continuously, isolating a compromised device into a microsegment in real time.
Director
The same console and uniform policy language that manage SD-WAN and SSE now manage the LAN — one policy model from the switch port to the cloud, single pane of glass.
Analytics
Complete LAN visibility — every device (managed and IoT), every port, every flow — in the same data lake as the WAN and user security telemetry.
One OS from switch port to cloud — inspection at the port, one Director policy, one data lake with WAN and users.
Twelve capabilities. One switch port.
Everything the campus stack used to split across boxes — switch, LAN firewall, NAC — converged at the port.
Zero Trust at the Switch Port
Identity, posture and policy decide access when a device plugs in; a network connection earns no implicit trust.
Real-Time Microsegmentation
AI/ML UEBA and device posture isolate a compromised or degraded device into a microsegment in real time — the blast radius contained closest to the host.
IoT & OT Security
Discovers, profiles and protects the unmanaged IoT and OT devices flooding modern campuses — cameras, sensors, badge readers — that can't run an agent.
Inline IPS at the Edge
Intrusion prevention runs at the access switch — threats detected at the first port where traffic enters the network, not after they've traversed the LAN.
Malware & AV Inspection
Anti-malware and antivirus inspection at the switch port — the full UTM stack applied at the LAN edge, no backhaul to a central firewall.
CASB at the LAN Edge
Cloud-app visibility and control applied right at the switch — the same CASB engine as Versa SSE, now enforcing on LAN-originated SaaS traffic.
DLP at the Port
The same DLP dictionary as SSE, enforced at the LAN edge — sensitive data controlled from the switch port, not just at the cloud gateway.
Converged Switch/Router/Security
Switching, routing, security and network services in one VOS™ stack, replacing access switch, LAN firewall and NAC appliance.
AI/ML Behaviour Analytics
Continuous user- and entity-behaviour analytics on LAN traffic — flagging compromised accounts and misbehaving devices by anomaly, not signature.
One Policy, Port to Cloud
The same uniform policy language and Director console as SD-WAN and SSE — zero trust defined once, enforced from the switch port to the cloud gateway.
Complete LAN Visibility
Every device, port and flow — managed and IoT alike — in the same analytics lake as the WAN, ending the campus-LAN blind spot.
One Platform, User to LAN
The final piece of single-vendor zero trust: users (SSE), sites (SD-WAN) and now the campus LAN (SD-LAN), all on one OS, one console, one policy.

Most campus LANs still trust whatever plugs in and backhaul inspection to a firewall. Here’s how Versa differs.
The LAN was the last flat, trusted world
SASE secured users and the WAN, but the campus and branch LAN stayed implicitly trusted: plug into a switch port and you're on the network. That flat trust is exactly where a compromised device or rogue IoT gadget spreads. Secure SD-LAN extends zero trust down to the switch port — closing the last implicitly-trusted layer.
Security at the port, not backhauled
Traditional LANs send traffic to a central firewall for inspection — lateral movement happens before anything sees it. Versa runs full inspection (IPS, malware, CASB, DLP, UTM) at the access switch, so threats are caught at the first port they enter, closest to the host.
IoT and OT, finally covered
Modern campuses are flooded with unmanaged devices — cameras, sensors, badge readers, medical and OT gear — that can't run an agent and are attackers' favourite foothold. Secure SD-LAN discovers, profiles and protects them natively at the LAN edge, closing a blind spot NAC bolt-ons never fully solved.
Real-time microsegmentation contains the blast
AI/ML UEBA watches every device; the moment one is compromised or degraded, it's isolated into a microsegment automatically — the blast radius contained at the host, not after it's spread across the LAN. Containment by architecture, not by incident response.
One OS, user to LAN — the whole picture
This is the final piece of single-vendor zero trust: users on SSE, sites on SD-WAN, and now the campus LAN on SD-LAN — all VOS™, all one Director console, all one uniform policy language. Zero trust defined once and enforced everywhere, instead of a NAC vendor, a switch vendor and a firewall vendor arguing at the port.
Converged hardware, collapsed stack
One VOS™ box does switching, routing, security and services — collapsing the access switch, LAN firewall and NAC appliance into one. Fewer boxes, one console, one policy, and the sharp challenger commercials TechBag negotiates from, with GST-compliant Indian quotes.
The architecture in numbers
What your SD-LAN rollout looks like
Campus & IoT discovery
TechBag maps campus LANs, managed and IoT/OT devices, and port-level zero-trust gaps, then sets a pilot site and criteria.
Pilot site SD-LAN
Versa switches/APs deployed at one site; zero trust at the port live; IoT devices discovered and profiled; microsegmentation tested.
Inspection & policy
Full UTM inspection at the switch enabled; unified policy extended from SSE/SD-WAN to the LAN; the campus blind spot closed in analytics.
Campus rollout
Sites converted in waves; access switches, LAN firewalls and NAC appliances collapsed into the converged stack. TechBag models it in INR/GST.

Quick poll — what’s driving your evaluation?
Talk to an advisor“The campus LAN was our last flat, trusted network. Now a device earns access by identity and posture, not by being plugged in.”
“A compromised laptop was microsegmented at its own switch port in real time, before it moved laterally. Blast radius: one host.”
“Cameras and sensors no agent could touch are now discovered and protected at the LAN edge, closing the blind spot NAC left.”
“One OS from user to WAN to LAN, one Director console and one policy, not three vendors arguing at the port.”
“It collapsed our access switch, LAN firewall and NAC appliance into one box. Fewer boxes, one policy, simpler operations.”
“As the first SD-LAN with native zero trust it is newer than a Cisco campus stack, but for a Versa shop it was the coherent choice.”
“Complete device visibility — managed and IoT — in the same analytics as our WAN. The campus finally stopped being a data black hole.”
“For a Versa SASE customer this is the missing piece — zero trust that finally reaches the switch port, not just the user and the branch.”
Where everyone sits — the grids
Analyst firms bury this view behind paywalls, and review-site grids score satisfaction, not fit for your estate. So here’s TechBag’s synthesis of the secure campus LAN market — tap any vendor to see why it sits where it does.
TechBag Secure Campus LAN Market Grid
Execution strength vs product vision — the classic market map, minus the paywall.
The zero-trust-to-LAN pioneer: industry-first SD-LAN with native ZT + IoT security, on the same OS as its Gartner-Leader SD-WAN. Younger in campus mindshare than Cisco/Aruba — pricing and platform-unity reflect it, in your favour.
Port-Level Security × Campus Depth
The grid nobody publishes — who inspects at the switch port, against campus networking depth.
The unified corner: zero trust and full security inspection AT the switch port, on the same OS as user (SSE) and site (SD-WAN) security. Nobody else runs one policy from port to cloud.

The 8 questions to ask every campus LAN vendor
Take this into your next vendor call — including ours.
Does a device earn access by identity and posture at the switch port — or does plugging in still grant implicit trust?
Is full UTM (IPS, malware, CASB, DLP) applied AT the access switch, or backhauled to a central firewall?
Are unmanaged devices (cameras, sensors, OT) discovered and protected natively — or is that a separate NAC product?
When a device is compromised, is it isolated into a microsegment in real time and automatically — or manually, later?
Is LAN policy the same OS, console and language as your user (SSE) and site (SD-WAN) security — or a different tool?
Does one box do switching, routing and security — or do you still run separate switch, firewall and NAC appliances?
Do you get every device and flow (managed + IoT) in one analytics lake with the WAN — or is the campus a black hole?
Model the collapsed-stack TCO: switch + firewall + NAC replaced by one converged VOS™ box. TechBag quotes it in INR/GST.
