ziti

OpenZiti is an open-source zero-trust networking platform that makes network services invisible and accessible only to authenticated, authorized users or workloads. It replaces traditional VPNs and firewalls by using cryptographic identity instead of IP addresses, with end-to-end encryption and no exposed listening ports.

What ziti is

OpenZiti provides a programmable overlay network with identity-based access control, mTLS authentication, and libsodium-based end-to-end encryption. It supports three deployment models: network-level routers (no code changes), host-level tunnelers, and embedded SDKs for applications. Built in Go with a full REST API and web console for policy management.

Quickstart

Best use cases

Replace Traditional VPN Infrastructure

Eliminate VPN concentrator bottlenecks and split tunneling vulnerabilities. Each service is individually authorized with fine-grained identity-based policies, avoiding the 'once in, access all' problem of legacy VPNs.

Dark APIs and Internal Services

Make APIs and services completely invisible to the internet with zero listening ports. Reduces attack surface to near-zero; only cryptographically authenticated clients can establish connections.

Multi-Cloud and Hybrid Workload Connectivity

Connect services across AWS, Azure, GCP, on-premises, and edge without cloud-specific networking tools, VPN tunnels, or complex peering. Single overlay network with identity-based routing.

Implementation considerations

Deployment model choice (network vs. host vs. application access) significantly affects complexity, code changes, and security posture—plan this decision early.
Identity and policy management at scale requires a process: how are identities created, revoked, and audited? The platform provides APIs and console, but operational procedures are your responsibility.
Edge router placement and mesh fabric resilience must be designed for your infrastructure; no automatic multi-region failover is documented in the provided data.
Tunneler or SDK integration requires testing with your application stack; compatibility with legacy frameworks or closed-source services may require network-level deployment instead.
End-to-end encryption and mTLS add CPU overhead on clients and routers; benchmark for your expected connection volume and throughput.

When to avoid it — and what to weigh

Requires Minimal Operational Overhead — OpenZiti deployment, policy management, and identity enrollment require operational expertise. Simpler alternatives exist for teams with limited networking staff.
Legacy or Proprietary Protocol Constraints — Embedded SDK deployment requires application code changes. If applications cannot be modified or linked against new libraries, network/host-level access models have trade-offs in security posture.
Extremely High-Throughput Low-Latency Networks — Overlay networks add routing hops and encryption overhead. Not suitable for latency-critical or massive-bandwidth scenarios (e.g., HPC clusters, real-time trading) without careful performance validation.
Compliance with Specific Network Isolation Requirements — Some compliance frameworks mandate network-layer isolation tools (appliance-based firewalls, IPSec). OpenZiti's overlay model may require additional controls to satisfy auditors or regulators.

Security considerations

OpenZiti's design emphasizes cryptographic identity (not IP-based), end-to-end encryption (libsodium), mTLS authentication, and zero listening ports. Dark services reduce attack surface. Identity-based policies enable fine-grained access control and real-time revocation. No security audit or penetration test results provided in data. Operational security depends on: identity lifecycle management, policy design rigor, controller and router hardening, and secure enrollment processes. Controller compromise could affect network-wide policy. Encryption strength depends on underlying cryptographic library implementation and key management. No disclosed CVEs or known vulnerabilities mentioned in data.

Alternatives to consider

HashiCorp Consul Service Mesh or Envoy Proxy

Both provide service-to-service encryption and identity-based access, particularly suited to Kubernetes. Less suited to legacy applications or dark services; typically require sidecar deployment or ingress patterns.

WireGuard or IPSec VPN

Lightweight, kernel-based encryption with lower overhead. Lack identity-based policy, multi-cloud support, and dark service capabilities. Better for simple site-to-site or point-to-point scenarios.

Tailscale or Netmaker

Simpler, more opinionated zero-trust mesh VPNs with lower operational overhead. Less flexible for dark services and application-level integration; Tailscale is proprietary SaaS, Netmaker is OSS but different architecture.

Software development agency

Build on ziti with DEV.co software developers

Start with a local quickstart (Docker or CLI) to understand the three deployment models. Then assess operational readiness: identity management process, policy framework, and router/controller placement for your infrastructure. Consult the production deployment guides and community forum for your specific use case.

ziti FAQ

Do I need to modify my applications to use OpenZiti?

No for network or host access models (edge routers, tunnelers). Yes for the strongest security posture using embedded SDKs. Most teams start with tunnelers (no code changes) and migrate to SDKs for new services.

How does OpenZiti handle high availability and failover?

The platform supports a mesh fabric with intelligent routing. Specifics on multi-region failover, controller redundancy, and router resilience patterns are not detailed in provided data; see production deployment documentation.

Can I use OpenZiti with Kubernetes?

Yes. README mentions connecting Kubernetes services to other clusters, VMs, and IoT devices. Implementation approach (sidecar, router, SDK) depends on your use case; details are not in provided data.

Is OpenZiti FIPS or compliance-certified?

Not mentioned in provided data. Audit status, certification eligibility, and compliance claims (SOC 2, HIPAA, PCI-DSS, FedRAMP) require separate verification.
