The most secure API is the one attackers can't find
WAFs and API gateways filter traffic that has already arrived. CloakNet prevents unauthorized traffic from ever arriving: your APIs become dark services, reachable only by authenticated, authorized identities across the zero trust overlay.
Public endpoints mean permanent exposure
Discovery & scraping
Anything with a DNS name and open port gets enumerated, fingerprinted and probed within minutes of going live.
Credential & token abuse
Stolen keys work from anywhere when the endpoint answers everyone. Authentication after connection is too late.
Zero-day windows
Every exposed gateway, load balancer and framework is one CVE away from pre-auth compromise.
Authenticate before connect
With CloakNet, an API is published into the overlay as a named service with no public listener. Callers — apps, partners, microservices, even SDK-embedded clients — must present a valid cryptographic identity and pass policy before a session is established.
- No open inbound ports, no public DNS footprint for private APIs
- End-to-end mTLS from caller to API workload
- Per-API, per-identity, per-operation policy
- Embed connectivity in apps via SDKs for true app-to-API zero trust
- Works alongside your existing gateway, tokens and rate limiting
High-value API scenarios
- Partner & B2B APIs without public exposure or IP allowlists
- Internal microservice APIs across clouds and clusters
- Payments, healthcare and other regulated data APIs
- Admin and management planes that should never be public
- Mobile/desktop apps calling private backends directly
Dark APIs in three steps
Host an endpoint beside the API
A lightweight tunneler or sidecar makes an outbound connection into the fabric and publishes the API as a private service.
Issue identities to callers
Services, partners and apps enroll with strong cryptographic identities — SDK-embedded, agent-based, or via gateway.
Close the public listener
Remove the public route. Callers reach the API by service name through the overlay; unauthenticated traffic has nowhere to land.
