Secure rails for your management plane
and the AI running on it.
ZoneRanger carries every management protocol across security boundaries on a single authenticated, encrypted channel — bounding the blast radius of anything that goes wrong, human or autonomous.
• One firewall rule
• Zero trust by policy
• Vendor-independent
ARCHITECTURE
Every protocol. One channel. One firewall rule.
Instead of opening dozens of ports through the perimeter, ZoneRanger multiplexes all management traffic over a single mutually-authenticated TLS connection between the Ranger Gateway and each ZoneRanger.
Illustrative — one mutually-authenticated TLS channel on port 4854 carries every management protocol across the boundary.
WHY IT MATTERS
Control the management plane — and bound what can go wrong.
The protocols that run your network are also its biggest attack surface. ZoneRanger turns that surface into a single governed path.
BUILT FOR THE AI ERA
Bounded blast radius — by design
Every management action is permitted by explicit policy, not by the absence of a block. A compromised management server — or an AI automation agent acting beyond its intent — can only reach the specific devices and protocols it’s authorized for. It cannot pivot through the management plane. As autonomous agents take on more of network operations, that bounded blast radius stops being a convenience and becomes an essential safety property.
ONE RULE
Collapse the firewall sprawl
Replace dozens of per-protocol ports with a single TCP connection — eliminating over 95% of the firewall rule changes tied to IT operations.
ZERO TRUST
Explicit permission, not absence of a block
Proxy Access Control defines which protocols reach which devices from which sources. ZoneRanger won’t relay anything that isn’t explicitly allowed.
ELIMINATE NAT PAIN
Overlapping IPs, solved
Address Transform lets one management system uniquely address every device, even when sites reuse the same RFC 1918 ranges — no per-firewall NAT tables.
TRANSPARENT
Invisible to your tools and devices
Management apps address devices by their real IPs; devices answer as if locally polled. No agents on managed devices, no application changes.
GOVERNANCE + AGILITY
A safe sandbox for IT operations
Once a zone’s single connection is permitted, that zone is fully manageable — new devices, applications and protocols need no further firewall changes. Security teams govern the perimeter as strictly as ever, while operations, and the AI working alongside them, get the reach they need.
PROTOCOL COVERAGE
Carries every management protocol you run.
Outbound requests, inbound telemetry, and authentication all ride the same encrypted channel — demultiplexed to native protocols on the far side.
OUTBOUND PROXY
Reach & manage devices
SNMP • ICMP • SSH • HTTP/S • FTP/TFTP • Generic TCP
INBOUND TELEMETRY
Collect & forward events
Traps • Syslog • NetFlow • IPFIX • sFlow • OTLP • Cloud
AUTH & INFRASTRUCTURE
Secure the control path
Auth/SSO • NTP • DNS • Inbound TCP • Secure TCP (TLS)
BUILT FOR
Wherever a boundary stands between you and what you manage.
Zero trust & AI operations
Bound the blast radius of compromised tools and autonomous agents across the management plane.
Managed service providers
Manage hundreds of customer networks — overlapping IPs and all — from one platform, one connection per site.
Regulated industries
PCI, HIPAA, FedRAMP, NERC CIP: keep segmentation intact with an auditable, policy-compliant management path.
OT & industrial networks
Full visibility into plant-floor and ICS zones without touching device firmware or weakening isolation.
Multi-cloud & hybrid
Extend one management plane into every VPC and vNet — no inbound security-group rules when ZoneRanger dials out.
Distributed sites
One ZoneRanger per branch, one outbound connection — thousands of sites manageable with zero inbound rules.
WHY ZONERANGER
Not a VPN. Not a firewall. Not a NAT box.
A protocol-aware proxy that understands every protocol it carries — and is governed centrally as part of the Ranger platform.
Bidirectional join
The channel can be initiated from either side, so ZoneRanger adapts to your firewall policy instead of demanding a change to it.
Many-to-many mesh
Gateways and ZoneRangers form a mesh across every zone. New site? Deploy a ZoneRanger. New app? Add a gateway. No new rules.
No agents on devices
Proxies standard protocols with no firmware, agent, or config changes on managed devices — ideal for fixed and OT gear.
Auditable & compliant
One justifiable rule at the perimeter plus per-protocol access policy gives auditors a clean, demonstrable control story.
Deploy anywhere
Physical appliance or VM, on-prem, cloud or OT plant floor — the same security properties everywhere.
Increased visibility
Visualize traffic by type, data received, processed, forwarded, and discarded. See traffic patterns by source and destination device, port, and protocol.
Extend management everywhere — without extending your attack surface.
