Build a Full Network Security
Stack on OPNsense
With Zenarmor.
A radically simple distributed network security platform that deploys anywhere in minutes. Enforce security at the nearest point and manage everything from a single unified system. Zenarmor Secure Access Service Edge (SASE) helps secure remote, roaming, and on-network users with centralized security policy enforcement, visibility, and management powered by Zenconsole™.
Unified, simple, and fast enterprise SASE deployed directly on the OPNsense nodes you already operate.
Deploys in minutes. No cloud backhaul. No vendor lock-in.
Why Customers Pick Zenarmor SASE Over Zscaler, Cato, or Netskope
Modern work happens everywhere. Your SASE security should, too. Zenarmor delivers enterprise-grade protection directly on the OPNsense infrastructure you already operate across offices, remote users, branches, and roaming devices.
| Benefit | Zenarmor | Other vendors |
|---|---|---|
| Keep All Traffic In Your Jurisdiction | Inspection happens on your premises, on your devices, with your keys. Data never leaves the jurisdiction you control. | All traffic processed in vendor-controlled cloud; compliance requires data-handling agreements |
| Live in Minutes, Not Months | New sites and tenants productive the same day they sign. Deploys in minutes. | Complex deployments that take weeks or months to fully roll out |
| Less Complexity, Easier Management | One unified platform. Lower operational overhead, fewer consoles, one vendor relationship. | Multiple products and consoles that increase operational complexity |
| Instant Connection, Better User Experience | ~0.2 ms local inspection, security that feels invisible | 20 ms minimum added on every connection, up to 300 ms+ depending on PoP distance |
| Security Without Slowing Users Down | Users stay productive with fast uploads, downloads and everyday access | Users report 60–80% throughput loss on large file transfers |
Instant deployment. Simple management. Enterprise SASE built for modern distributed organizations.
Meet Zenarmor SASE
A complete Secure Access Service Edge platform with NGFW, ZTNA, Secure Web Gateway, CASB, DLP, and DNS security, running on the OPNsense nodes you already trust and managed from a single cloud console.
Deploy security where you need it. Zenarmor SASE runs directly on OPNsense gateways, branch firewalls, cloud gateways (AWS, Azure, GCP), endpoints and roaming users, and containerized environments.
Cloud SASE Solved One Problem and Created Others
By pushing every packet to a distant vendor PoP for inspection, cloud-only SASE introduced latency, throttled throughput, locked customers into proprietary clouds, and sent sensitive traffic out of the jurisdictions where it belongs.
Backhaul Latency
Cloud-only SASE users report throughput slashed from 500 Mbps to 30 Mbps and round-trip latency jumping from a stable 5 ms to 11–280 ms when every packet is hair-pinned through a vendor PoP.
Implementation Lag
Policy changes that should be instant take 15–45 minutes to commit in cloud SASE platforms. Add fragmented portals between firewall, VPN, SWG, and ZTNA, and "from design to operations" stretches from minutes into days.
Data Sovereignty
Sensitive traffic processed in a foreign jurisdiction creates compliance and privacy headaches.
Forklift Refresh Required
Most cloud SASE platforms require you to retire perfectly good firewalls and roll out new vendor-specific appliances at every site, an expensive, disruptive hardware refresh just to get started.
Renewal Tax
Per-user pricing as high as $130/user, with cloud SASE customers reporting ~20% renewal hikes year over year. Costs compound while platform value flatlines.
Inspection Blind Spots
ZTNA without inline inspection just authenticates the door, it doesn't watch what walks through.
Key Pillars of a Real SASE Edge
Next-Gen Firewall
Layer 7 application control, deep packet inspection, and cloud threat intelligence enforced at every OPNsense site.
Zero Trust Network Access
Direct, encrypted, identity-based tunnels for remote users and contractors. No VPN concentrator. No broad network exposure.
Secure Web Gateway
URL category filtering, SafeSearch, and content controls for every user, every site, every device.
CASB
Surface shadow IT and govern SaaS usage. Identify, classify, and control thousands of cloud applications by name, with risk scoring and per-app policy.
TLS Inspection & Deep Packet Inspection
See inside encrypted traffic and classify applications, protocols, and content at Layer 7, locally on the firewall, so threats hiding in TLS get caught without shipping data to a vendor cloud.
Cloud-Native Management
One Zenconsole for policy, analytics, reporting, and orchestration across every OPNsense node, whether you have five sites or five hundred.
One Platform. One Console. Every Site.
Zenconsole unifies firewall policy, remote-access rules, web filtering, and analytics across every OPNsense node. Push changes globally. Drill into a single user's session. Export audit reports in one click.
One ruleset for firewall, ZTNA, and SWG. No more cross-tool reconciliation.
Live drill-down on every user, every app, every site.
From a single site lab to thousands of remote users without changing architecture.
"We evaluated Zscaler but realized Zenarmor gave us the same outcome with far less complexity. Setup took an afternoon."

Frequently Asked Questions
Do I need to replace my OPNsense firewall?+
No. Zenarmor SASE installs as an OPNsense plugin and uses the firewall you already operate as the SASE enforcement point.
How is this different from cloud-only SASE like Zscaler?+
Cloud SASE routes all traffic through vendor PoPs. Zenarmor SASE keeps inspection at your edge, direct-to-SaaS performance with no backhaul tax, while still giving you cloud-based management.
How does pricing work?+
Pricing is per site and per user with no per-module nickel-and-diming. A free tier is available for evaluation and small deployments.
Can I cover remote workers and contractors?+
Yes. The ZTNA module gives remote users direct, identity-based encrypted tunnels into authorized applications, no VPN concentrator required.
What about IoT, printers, and devices without an agent?+
Agentless devices are protected at the OPNsense gateway with full L7 inspection, threat intel, and microsegmentation. All with the same policy plane as agented users.
Where is my data processed?+
Traffic inspection happens locally at your OPNsense edge; we are sovereign by design. Only metadata for reporting and policy sync flows to Zenconsole, and EU/regional data residency is supported.
