NetFoundry

NetFoundry is an identity-first zero-trust connectivity platform for AI, API, and machine-to-machine workloads. It suits organizations joining services across public cloud, owned infrastructure, and isolated environments while enforcing least-privilege access. The main trade-off is a deployment that needs deliberate identity and policy administration, with pricing determined for each deployment.

Overview

NetFoundry is built around outbound workload connections rather than exposed listening ports. Identity determines which services can communicate, making the platform a strong candidate for microsegmentation and service-to-service controls across IT, OT, IoT, APIs, AI agents, models, and tools. Teams looking for a conventional user VPN or a quick, individually managed tunnel may find this workload-centric approach more involved than necessary.

Deployment can be managed by NetFoundry or operated by the customer. NetFoundry Cloud uses dedicated controllers and routers deployable on AWS, Azure, Google Cloud, and Oracle Cloud. NetFoundry Self-Hosted runs on customer-owned infrastructure, including on-premises and air-gapped environments. That range is valuable where data-location or isolation requirements rule out a single-cloud design.

Key features

Before a connection is made, mutual X.509 authentication verifies both endpoints. Access then follows identity and least-privilege policy, while workloads initiate connections outbound without open or listening ports. This can reduce the attack surface for distributed services, but it also means administrators must maintain trustworthy identities and precise policy relationships as the environment changes.

The platform records authentication, authorization, and policy changes. Audit events can be streamed, and connection, throughput, and health metrics can be exported; SIEM log export is supported. Device posture checks add another access signal. These capabilities give security and operations teams material for investigations and ongoing control rather than only a connectivity pipe.

NetFoundry connects to external identity providers and documents SCIM for automated identity management. SDKs for Go, C, .NET, Java, Node, and Swift help teams embed connectivity into applications written in common enterprise languages. TCP and UDP support covers both conventional application traffic and latency-sensitive or non-HTTP services.

Pricing

NetFoundry uses custom pricing, so buyers need a quote for the required deployment and support arrangement.

NetFoundry Cloud

This plan includes a dedicated network, managed infrastructure, an uptime SLA, and 24×7 support. It fits organizations that want NetFoundry to operate the core service while they apply workload and identity policy. The operational convenience comes with less infrastructure ownership and no published price for budgeting.

NetFoundry Self-Hosted

This option puts the infrastructure under the customer's management and supports on-premises, air-gapped, or cloud deployment, with 24×7 support. It is the better match for strict isolation, sovereignty, or existing platform-operations requirements. Customers take on the infrastructure responsibility, and its price is also custom.

Support packages include Select and Premium, with platform-availability SLAs of 99.5% and 99.95%, respectively. Some support packages are not offered in every region, so location should be confirmed before committing to a target SLA.

Platforms

NetFoundry lists Android, iOS, Linux, macOS, Windows, web, and API access, plus self-hosted deployment. Its hybrid deployment model and support for both access methods make it suitable for mixtures of managed services, private infrastructure, and application-integrated connections.

Who it's for

Security and platform teams governing AI agents, models, and tools will value identity-based authorization and auditable policy changes. Enterprises segmenting microservices, industrial systems, IoT fleets, or APIs can use the outbound model to avoid exposing inbound ports. It is also appropriate for organizations that need cloud portability or air-gapped operation.

NetFoundry is less compelling for a small team seeking a free or transparent-price network access product, since both plans require a quote and workload identity design. Buyers should also ensure their preferred support tier is offered in their region.

Pros and cons

• Pros: Mutual X.509 endpoint authentication establishes trust on both sides before connection.
• Pros: Outbound-only connectivity and least-privilege policy reduce reliance on exposed service ports.
• Pros: Audit streaming, SIEM export, metrics, posture checks, and SCIM documentation support security operations.
• Pros: Managed cloud and customer-controlled self-hosting cover public-cloud, on-premises, and air-gapped requirements.
• Cons: Custom pricing makes cost comparison and initial budgeting harder.
• Cons: Identity and policy administration is central to the design, adding governance work for teams without mature security operations.
• Cons: Support-package availability varies by region, which can affect the SLA a buyer can obtain.

Alternatives

Choose Twingate when a freemium service with a free Starter tier, up to five users and 50 resources, and peer-to-peer connections is a better starting point.

Cloudflare One is a fit for teams wanting a freemium platform with a free plan capped at 50 users and up to 24 hours of standard log retention.

Pick OpenZiti for free, Apache 2.0, self-hosted and self-managed deployment with community support, or its hosted option.

Cloudflare Gateway suits buyers seeking a forever-free tier for 50 users or a $7 a month pay-as-you-go plan.

Dope Security CASB Neural is aimed at secure web access and cloud-app controls, with native Mac and Windows coverage.

Forcepoint Data Security Cloud, Skyhigh Private Access, and Symantec IT Management Suite are alternatives with custom or partner-led pricing.

For broader category comparisons, see Security Service Edge Software, Zero Trust Network Access Software, and Business VPN Software.

Verdict

NetFoundry is a strong choice for organizations that need identity-controlled connectivity between workloads across cloud, private, and isolated environments, especially where auditability and least privilege are priorities. Choose it for deployment flexibility and endpoint-level trust; look elsewhere if you need simple consumer-style access, a free tier, or predictable published pricing.
