+
+NetBird and Defguard both use WireGuard® for VPN connectivity. Both can be self-hosted. But their architectures, security models, and target audiences differ fundamentally.
+
+NetBird is primarily a cloud service focusing on WireGuard® mesh networking—one network, peer-to-peer connectivity, ease of use. Defguard is an on-premises-first enterprise VPN built for secure remote access using a secure-by-design architecture and service segmentation.
+
+In this article we compare the two approaches, explain when each shines, and help you choose.
+
+## At a Glance
+
+**NetBird** requires all components—both control and data planes—to be publicly exposed, whether you use cloud or on-premises. This creates a broader attack surface and represents a single point of failure. The mesh paradigm places all devices on a single flat IPv4 network, with traffic management via ACLs in the mesh graph.
+
+**Defguard** keeps its control plane—which integrates with external SSO and IdP solutions—completely isolated from the public internet. Public-facing components remain stateless and secure. Centralized gateways enable traffic inspection, compliance logging, and hierarchical user/device management that enterprises expect.
+
+## Secure-by-Design: Why Isolating the Control Plane Matters
+
+Whether using cloud or on-premises, NetBird runs all components within a single network (e.g., one machine or Docker network) and then exposes them collectively to the public internet.
+
+This approach shares the same inherent weakness as the SSL VPN architecture now being phased out by enterprise vendors (see [Fortinet's move to IPsec](https://docs.fortinet.com/document/fortigate/7.6.3/fortios-release-notes/173430/ssl-vpn-tunnel-mode-replaced-with-ipsec-vpn)). **Most attacks do not target the VPN protocol itself, but rather the management endpoints.** Two primary vulnerabilities apply:
+
+- **Application Layer Exposure:** Exposing the VPN on a firewall makes the main VPN data plane publicly accessible.
+- **Control Plane Exposure:** Configuration portals for user/device enrollment require exposing the VPN control plane to the public.
+
+Despite using WireGuard®, NetBird follows this risky model by exposing both control and data planes—prioritizing ease of deployment over enterprise security expectations.
+
+Defguard was designed with security as the top priority, delivering the [secure-by-design (SBD) approach](https://docs.defguard.net/in-depth/secure-by-design). The key differentiator is **segmentation of systems and components**.
+
+Communication between components is designed to prevent lateral movement from public (proxy, gateway) to private (core) network segments. This can be achieved via separate VLANs or multiple firewalls. The segmented approach significantly reduces attack surface and makes the system more resilient.
+
+## Advanced Identity Security & Native MFA
+
+While NetBird only supports MFA through external SSO providers, Defguard goes further. In addition to external SSO, Defguard enables:
+
+- TOTP (Authenticator codes)
+- Email codes
+- Mobile app biometrics
+- Multi-device desktop authentication with mobile biometrics
+
+NetBird's authentication mainly handles peer configuration. **Defguard's MFA provides multiple security layers**, including the exchange of additional security keys at the protocol level.
+
+## Memory Safety: Rust vs Go
+
+NetBird is implemented in Go; Defguard is written in **Rust**—a memory-safe language recommended by leading security organizations:
+
+- [NSA Memory Safety](https://www.nsa.gov/Press-Room/News-Highlights/Article/Article/3215760/)
+- [CISA/NSA Joint Guidance](https://www.cisa.gov/sites/default/files/2023-12/The-Case-for-Memory-Safe-Roadmaps-508c.pdf)
+- [DARPA TRACTOR](https://www.darpa.mil/research/programs/translating-all-c-to-rust)
+- [ANSSI Rust Guide](https://github.com/ANSSI-FR/rust-guide)
+
+Memory safety eliminates entire classes of vulnerabilities (buffer overflows, use-after-free) at compile time, providing stronger guarantees for security-critical infrastructure.
+
+## Mesh vs Centralized: Architecture for Security & Compliance
+
+Mesh networking provides flexibility but is often unsuitable for enterprise environments:
+
+- **Flat Network Structure:** All devices on a single shared IPv4 network
+- **Access Control Complexity:** Traffic management relies on ACLs in the mesh graph—difficult to audit and manage at scale
+- **No Centralized Traffic Inspection:** Peer-to-peer traffic bypasses corporate firewalls and IDS/IPS, creating security blind spots
+- **Complex Compliance:** Gathering unified logs for SOC2 or ISO27001 is difficult across a decentralized network
+- **Higher Lateral Movement Risk:** A compromised endpoint can move laterally more easily in a flat mesh
+- **Difficult Troubleshooting:** Diagnosing peer-to-peer NAT traversal failures is complex without central gateway logs
+- **Endpoint Resource Overhead:** Multiple active tunnels drain battery and CPU on mobile devices
+
+Defguard adheres to enterprise standards with centralized network management:
+
+- **Strict Network Segmentation:** Users reach only authorized subnets or services—true Zero Trust
+- **Centralized Traffic Inspection:** Traffic flows through gateways, integrating with firewalls, IDS/IPS, and DLP
+- **Simplified Compliance Logging:** Straightforward collection of unified access logs for SOC2, ISO27001, NIS2
+- **Agentless Access:** Route traffic to internal subnets without VPN clients on every server or database
+- **Reliable IT Troubleshooting:** Single point of truth (gateway logs) for diagnosing connectivity issues

+
+## When Mesh Shines: The Appeal for Small Teams
+
+For smaller, agile teams without dedicated IT, mesh networking has clear advantages:
+
+- **Zero Infrastructure:** No central VPN gateway or firewall to deploy—the network runs on users' devices
+- **Direct Peer-to-Peer Speed:** Devices connect directly for lower latency—ideal for file sharing or accessing a colleague's local dev environment
+- **Effortless NAT Traversal:** Mesh solutions excel at punching through home routers, hotel Wi-Fi, or cellular networks
+- **Plug-and-Play Connectivity:** All devices on one flat IP network—install the app, log in, and see every other device immediately
+
+NetBird also offers features that Defguard is still building: Device Posture Checks, Magic DNS with split-DNS routing, Service Exposure (integrated reverse proxy for internal apps), MDM integration (Kandji, Jamf, Intune), and EDR integration for automated threat containment.
+
+## Summary
+
+**Choose Defguard** when you need enterprise-grade security: isolated control plane, centralized traffic inspection, compliance-ready logging (SOC2, ISO27001, NIS2), and hierarchical user/device structure. Ideal when reducing attack surface and meeting audit requirements are non-negotiable.
+
+**Choose NetBird** when you're a small team prioritizing zero infrastructure, direct peer-to-peer speed, and plug-and-play connectivity—and when Device Posture, Magic DNS, Service Exposure, MDM, or EDR integration are essential today.
+
+Both use WireGuard®. The difference is architecture, security model, and target environment. For enterprises, Defguard's secure-by-design approach and control plane isolation deliver the resilience and visibility that compliance and security teams expect.
