NetBird lands fresh funding to rethink secure remote access
Berlin-based startup NetBird has raised €8.5 million to accelerate the development of its European, open-source alternative to legacy SSL VPN solutions. The company aims to simplify secure connectivity for distributed teams and cloud-native infrastructure, positioning itself as a privacy-conscious counterweight to dominant US-based vendors.
The funding round underscores growing demand for modern, developer-friendly networking tools that can securely connect users, applications and devices across multiple clouds and on-premise environments without the complexity of traditional VPN stacks.
A European open-source answer to legacy VPN complexity
NetBird is building a software-defined, peer-to-peer networking platform designed to replace brittle, hardware-centric SSL VPN appliances. Instead of relying on centralized gateways and static tunnels, the platform creates encrypted, direct connections between machines and users, managed via a simple control plane.
By embracing an open-source model, the startup allows security teams and developers to inspect the codebase, contribute features, and avoid vendor lock-in. This approach is particularly attractive to European companies that must comply with GDPR and increasingly prefer infrastructure that can be self-hosted or operated within the EU.
While US vendors dominate the traditional VPN and remote access market, NetBird is betting that a transparent, European-built stack will appeal to organizations concerned about data residency, extraterritorial surveillance and long-term licensing costs.
Riding the zero-trust and cloud-native wave
Corporate networks have changed dramatically in the past decade, with employees working from anywhere and critical workloads running across multiple cloud providers and edge locations. In this environment, perimeter-based security and legacy SSL VPN concentrators often become bottlenecks and single points of failure.
NetBird aligns its product with modern zero-trust networking principles: every connection is authenticated, encrypted and governed by fine-grained access policies, regardless of where the user or service is located. Instead of extending a private network to every device, the platform grants access only to specific resources based on identity and role.
For DevOps and platform teams, this means they can securely expose internal services, Kubernetes clusters, databases and development environments without opening inbound ports or managing a patchwork of VPN configurations. Automated key rotation, policy-based routing and integration with existing identity providers aim to reduce both administrative overhead and attack surface.
Why investors are backing NetBird now
The €8.5 million injection comes at a moment when secure access infrastructure is being reevaluated across industries. Hybrid work has become permanent, regulatory scrutiny is tightening, and high-profile breaches frequently trace back to misconfigured or compromised VPN systems.
Investors are betting that a new generation of network security tools—built around automation, open standards and developer-first design—will replace legacy appliances in the same way that cloud-native databases and container platforms displaced older, monolithic stacks.
By focusing on Europe from day one, NetBird also taps into a growing policy and market push for digital sovereignty. Governments and enterprises across the region are actively seeking European alternatives in areas such as cybersecurity, cloud infrastructure and developer tooling, both to diversify supply chains and to keep sensitive data within EU jurisdictions.
Key product pillars: simplicity, security and transparency
Developer-centric onboarding
NetBird emphasizes ease of deployment, offering lightweight agents and infrastructure components that can be installed via standard package managers, container images and automation scripts. The goal is to allow teams to connect laptops, servers and cloud instances into a private, encrypted mesh network in minutes rather than days.
Configuration is managed through a central control plane and exposed via APIs and a web console, enabling integration with existing DevOps workflows and CI/CD pipelines. Role-based access controls and policy templates help security teams maintain consistency across environments.
Security by design
Under the hood, NetBird leverages modern encryption standards and peer-to-peer networking protocols to establish secure tunnels between endpoints. Because traffic flows directly between peers where possible, rather than through centralized gateways, the architecture can improve performance while reducing infrastructure costs.
The open-source nature of the project allows independent experts to audit the code, a critical factor for organizations that treat network security as part of their core risk posture. With the new funding, the company is expected to invest further in formal security reviews, bug bounty programs and compliance certifications.
Transparency and control for European customers
For many European enterprises, control over where metadata, logs and keys are stored is as important as the technical design of the VPN replacement itself. NetBird offers deployment options that allow customers to self-host critical components or run them within EU-based infrastructure providers, aligning with internal compliance requirements and external regulations.
This combination of technical transparency and operational control is central to the startup’s pitch as a European alternative to large, closed-source US vendors.
Competitive landscape and future roadmap
The secure remote access market is crowded, with incumbents in the SSL VPN space and newer entrants in zero-trust network access all vying for budget. NetBird differentiates itself through its open-source foundation, European roots and strong focus on developer experience.
With the fresh €8.5 million, the company is expected to expand its engineering team, enhance its management console, deepen integrations with identity providers and observability tools, and broaden support for enterprise use cases such as multi-tenant environments and advanced compliance reporting.
As organizations continue to modernize their infrastructure and security stacks, demand for flexible, transparent and regulation-friendly alternatives to legacy SSL VPN systems is likely to grow. NetBird is positioning itself to be one of the leading European names in that next generation of secure connectivity platforms.
