An on-premises option has been added to the end-to-end ‘networkless’ solution at Distributech 2025.
CHARLOTTE, N.C., March 24, 2025 — NetFoundry, a leading provider of embedded zero trust networking, has introduced a new version of its OT security platform. This platform allows customers to secure critical infrastructure, including on-premises and air-gapped environments like substations.
The announcement, made at Distributech 2025, addresses three key customer needs:
- OT microsegmentation that is software-only, interoperable, and vendor-neutral.
- Secure connection to IT and OEMs, without exposing the OT network, while also preventing data exfiltration.
- Reduced expenses related to firewalls, SIEM, SOAR, analytics, data lakes, and storage.
According to Galeal Zino, CEO of NetFoundry, “NetFoundry protects critical infrastructure across three continents, and we prioritize customer feedback. They consistently emphasize the need for straightforward security that reduces costs and complexity within their multi-vendor OT environments.”
Zino added, “Solutions limited to the firewall or specific vendors create unnecessary complexity and fail to address the evolving cybersecurity and microsegmentation demands of OT. Our unique approach, which denies all inbound data, allows IT and OT teams to render all firewalls and servers unreachable from underlying networks. This provides a security and operational advantage by eliminating complex access-control management. Additionally, it significantly reduces the costs of security and storage by minimizing superfluous data logs caused by port scanning and unauthenticated events.”
NetFoundry’s partner, FreeWave, announced in January that it was using NetFoundry and Keyfactor tech for its Industrial Internet of Things (IIoT) and wireless connectivity solutions to secure remote and embedded industrial edge operations.
Steve Wulchin, CEO of FreeWave, stated, “The VPNs and other security technologies we previously relied on are no longer sufficient in today’s hyperconnected world. NetFoundry’s technology enables us to enforce strict deny-by-default security principles for every user, device, and application on our customers’ networks. We welcome the addition of the on-prem option for customers who need to operate without depending on external connectivity, while still being able to securely use external edges and clouds when appropriate. Partnering with NetFoundry enables us to meet emerging requirements for secure-by-design products in connected environments, such as the EU Cyber Resilience Act (CRA).”
Rik Turner, senior principal analyst at Omdia, commented, “While zero trust technology has become popular for enabling secure remote access (SRA) in enterprise IT, it is even more essential in OT environments, where security is needed even for access originating within the organization’s premises. In such cases, SRA becomes a subset of a broader secure access requirement.”
Turner continued, “It is a logical step for NetFoundry to introduce an on-prem option for its platform, considering that many OT customers, especially those involved in critical national infrastructure, are unable or unwilling to use any cloud-based security capabilities for their environments.”
The NetFoundry OT security platform consolidates the OT firewall access control list (ACL) to a single inbound rule: deny-all inbound with no exceptions, even for communication with IT or OEM systems. The platform offers software-only microsegmentation for critical infrastructure, energy, and manufacturing, and is natively compatible with existing routers, firewalls, edge compute, and programmable logic controllers (PLCs). SecOps benefits from telemetry and analytics for threat response and regulatory compliance tracking, while IT management experiences lower costs.
OT and IT teams can deploy NetFoundry software on any server, including existing firewalls, edge cells, and PLCs. NetFoundry’s SDKs empower OEMs to integrate the software into industrial control system software, manufacturing machines, modems, routers, firewalls, PLCs, edge cells, and reverse proxies. Solutions that use NetFoundry software include , , , , and .
