The challenge

IT & OT Connectivity Needs Have Outgrown Traditional Networking

OT systems need more connectivity – for vendor support, condition monitoring, analytics, and IT & OT integration. But traditional network-centric approaches expand trust boundaries, increase change-control burden, and create governance sprawl.

The sprawl problem

Each new vendor, OEM, or system integration requires firewall rule changes, VPN deployments, or VLAN modifications – each one triggering change management cycles and adding to the attack surface. Meanwhile each vendor brings their own tunnel and access model, creating inconsistent controls across the enterprise.

  • VPNs give excessive access – remote vendors can often reach far more than they need
  • Jump servers are operationally complex and create single points of failure
  • Open inbound firewall rules expand the OT attack surface and violate IEC 62443 principles
  • VLAN changes require security and network reviews – slowing new capability delivery
  • Heterogeneous OEM access models — fragmented governance, compounding audit sprawl
  • No centralized visibility into who is accessing what, when, from where

The customer connectivity problem

Software and service providers face the same challenge in reverse: every customer deployment requires coordinating firewall rule changes, VPN setup, and IP allowlists on the customer side – triggering lengthy security reviews that delay revenue.

  • Customer IT teams required to open inbound ports or deploy VPNs before any connection can occur
  • Every customer deployment requires different firewalls, policies, and timelines
  • Lengthy security reviews triggered by firewall rule change requests
  • Excess access risk – VPN access often broader than necessary for the service being provided
  • Operational overhead maintaining IP allowlists and VPN configurations across hundreds of customers
The NetFoundry approach

Identity-First Connectivity Across Every Environment

NetFoundry decouples connectivity governance from the underlying network. An outbound-only overlay connects every site, device, and workload – without modifying firewalls, VLANs, or existing network infrastructure.

Simplify and centralize hybrid IT & OT site connectivity

Enable vendor access, telemetry collection, and IT & OT data flows – without opening inbound ports or modifying VLAN configurations. New access paths are created entirely through the NetFoundry overlay, leaving existing OT network infrastructure untouched.

  • No inbound ports – outbound-only from the OT environment
  • No VLAN or underlay network changes required for new access paths
  • Authorized, identity-bound conduits – default deny with service-level access
  • Standardize governance across all OEMs and vendors with one policy model
  • Available on Siemens network devices as Siemens SINEC Secure Connect
  • IEC 62443 aligned: FR-1 (identification), FR-2 (authorization), FR-5 (boundary protection), FR-6/7 (audit)

Replace VPNs with identity-based partner access

Give partners, suppliers, and third parties the exact access they need – no more, no less. Identity-based least-privilege replaces broad VPN tunnels that grant excessive network access.

  • No VPNs to deploy, manage, or troubleshoot for partner access
  • No open firewall ports or IP allowlists required
  • Each partner gets service-level access – only to the specific services they’re authorized for
  • Full identity-based audit trail of every partner connection and service call
  • Instant access provisioning and revocation – no infrastructure changes needed
  • Consistent governance model across all partners regardless of their network setup

Instead of maintaining complex per-partner VPN configurations or firewall exceptions, each partner identity gets a certificate-based connection to only the services they need – centrally managed through NetFoundry’s identity-based policy engine.

“NetFoundry helped us scale faster, safer, and more cost-effectively – eliminating VPN and NAT dependencies.”

Rodrigo Bernardinelli, CEO – Digibee

Deploy at customer sites in minutes, not weeks

Eliminate the deployment bottleneck that costs SaaS providers, MSPs, and software companies weeks of per-customer IT coordination. With NetFoundry, customers don’t need to open a single inbound port.

  • Customers deploy a lightweight connector – no firewall changes, no VPN, no IT review required
  • Your platform connects to customer environments via outbound-only overlay
  • Shorter sales cycles – fewer security objections, simpler security reviews
  • Faster revenue recognition – deployments in minutes instead of weeks
  • Centralized management of all customer connections from a single control plane
  • Works across on-prem, cloud, OT, and IoT customer environments without redesign

NetFoundry Customer Connect embeds Identity-First Connectivityâ„¢ directly into provider platforms. Customers deploy a connector alongside their existing infrastructure – no firewall rule changes, no VPN management, no IP allowlist coordination.

“Our customers don’t need to open a single inbound firewall port for us to manage our software.”

John Wilson, CEO – TZ Limited

Block lateral movement without network redesigns

Traditional microsegmentation requires complex VLAN configurations and ongoing firewall rule management. NetFoundry’s identity-based approach delivers microsegmentation as a policy – not a network architecture change.

  • Define access by identity and service – not IP address or network segment
  • Default deny: no lateral movement is possible unless explicitly authorized by policy
  • Instant policy updates – no firewall rule changes required to adjust segmentation boundaries
  • Works across existing networks – no VLAN redesign, no infrastructure changes
  • Full visibility into traffic by identity and service – not just IP and port
  • Simple to deploy incrementally – add segments progressively without disrupting existing connectivity

Post-breach lateral movement is the main way attackers turn a single compromised endpoint into a full network intrusion. NetFoundry’s policy-based approach makes lateral movement structurally impossible for unauthorized identities – regardless of which network they’re on.

“NetFoundry’s technology enables us to apply the strictest deny-by-default security principles to every user, device and application in our customers’ networks.”

Steve Wulchin, CEO – Freewave

How it works

Five Steps to Zero Trust Connectivity

NetFoundry’s approach works the same way across IT, OT, IoT, cloud, and partner environments – replacing network-centric models with identity-based access at every point.

1

Enable connectivity without underlay network changes

New access paths are created through the NetFoundry overlay – no changes to VLANs, firewall rules, or existing network infrastructure. Change management overhead is eliminated for new connectivity requirements.

2

Authenticate first, then connect via encrypted conduit

Mutual authentication using X.509 certificates establishes an encrypted conduit only after identity and policy are verified. No network access is granted by default – zero trust from the connection layer up.

3

Enforce least-privilege access

Access is defined by identity, workload, and service – not IP addresses or network location. Policies can be as granular as individual service endpoints, enabling true microsegmentation without network redesign.

4

Operate at scale with centralized governance

Centralized policy management and immutable logs support investigation, change control, and audit requirements across all sites, vendors, and OEMs – in a single consistent governance framework.

5

IEC 62443 alignment for OT environments

NetFoundry maps cleanly to IEC 62443 zones, conduits, and least-privilege requirements – supporting FR-1 (identification and authentication), FR-2 (authorization), FR-5 (boundary protection), FR-6/7 (audit and monitoring), and SR 2.6 (session termination).
