TunnelCrib vs. ZafePass by Zafehouze
ZafePass is a close conceptual comparison. Zafehouze publicly describes it as a prevention-first, service-level zero-trust access platform: users receive access to entitled services or resources only while they are using them, while other protected systems remain hidden. TunnelCrib follows a similar least-exposure idea, but its documented product boundary is a temporary Tunnel from TunnelCrib Client to one approved Service on one registered Device.
| Area | TunnelCrib | ZafePass |
|---|---|---|
| Access unit | One approved Service on one registered Device | Entitled service, resource, application, or data resource |
| Connectivity | Direct Client-to-Agent first, TunnelCrib Relay fallback, SSH transport | Zafehouze describes transit gateways/proxies, dual reverse-proxy VPC connectivity, and SSH2 between client and gateway |
| Exposure model | Agent advertises approved Services; the Client receives a temporary local port | Zafehouze describes micro-perimeters and ephemeral service paths that disappear when access is closed |
| Identity and policy | Organization and Device identity, nonce proof, per-Client/Agent/Service policy | Zafehouze describes MFA policy, user/device/environment attributes, group or user policy, and directory integrations |
| Deployment | Central Server, Agents, Clients, hosted or Private Relay | Zafehouze describes a software platform with on-premises deployment and gateway/proxy components |
| Positioning | Focused temporary connectivity to existing protocols | Broader access platform for IT, OT, IoT, applications, and data |
Where they are similar
- Both describe access at the Service or resource boundary instead of granting a full private-network view.
- Both support temporary or ephemeral access paths and hide unrelated protected systems.
- Both use encrypted proxy or Tunnel paths rather than requiring every protected Service to be publicly exposed.
Where TunnelCrib is different
- TunnelCrib has a narrower Device/Agent/Service model and a direct-first P2P path with Relay fallback.
- TunnelCrib's security documentation specifies registered Device keys, nonce signatures, per-Tunnel SSH credentials, Agent host-key pinning, organization boundaries, and durable Tunnel activity events.
- TunnelCrib is intended to preserve the Service's own protocol and credentials; it does not present itself as a complete MFA, PAM, directory, or compliance platform.
Where ZafePass appears broader
- Public Zafehouze material describes access to IT, OT, and IoT resources, policy attributes, MFA, Active Directory integration, and multiple network segments.
- Zafehouze describes on-premises operation and gateway failover/load sharing as product capabilities.
- The public material also contains strong security and “uncompromisable” marketing claims; those claims should be validated through architecture review, independent testing, and contractual evidence.
Choose TunnelCrib when…
- the requirement is a small, explicit, auditable Tunnel to one Service on one Device
- temporary support or customer access is the primary workflow
- direct-first P2P and a simple Agent/Service model are sufficient
Choose ZafePass when…
- access must span multiple segments, IT/OT/IoT assets, applications, or data
- MFA, user/device/environment attributes, and broader policy controls are required
- an on-premises gateway and wider access platform are preferred
