Your SaaS needs data from your customer’s network.
Get it without the VPN circus.
Your customers' APIs, databases, and internal tools live behind firewalls you don't control. ngrok gives your SaaS secure, scoped access without hopping on calls with IT to open firewalls or detangle VPC peering.
One agent per customer. Every service on their network.
Your customer runs a lightweight agent behind their firewall. It dials out to ngrok over an outbound-only reverse tunnel to give you private endpoints for the APIs, DBs, and services you're authorized to reach.
Customers run a lightweight agent that creates secure tunnels: outbound TLS connections from agents to the ngrok cloud on port 443.
Authorize connections with your choice of mTLS, IP restrictions, or JWTs. ngrok relays traffic from your cloud directly to the target service.
Connections from your cloud to ngrok are wrapped in mTLS by the ngrok Kubernetes Operator. Only your cluster can ping the URL, so there's no need for auth.
Not running in Kubernetes? We also support private URLs with our agent CLI and Go SDK. Talk to an engineer
Access more services on other protocols with one setup—DBs, web apps, IoT devices, and much more.
Expand from one to many customers with the same agent configuration and new private endpoints.
Why ngrok?
Customers go live in days, not weeks. Fast onboarding means faster revenue and far fewer ‘is it working yet?’ emails.
Keep customer networking out of your support queue. Focus on what makes your product different and valuable.
One integration works the same everywhere. Any enterprise topology: AWS, Azure, on-prem, or hybrid.
Pass your customer security review on the first try.
The ngrok agent already runs in banks, healthcare systems, and Fortune 100 networks. Your customers' security teams have seen it before.
Access a service, not your customer's whole network
Tightly scope your access to the APIs and databases you need and not a single port or process more.
Encrypt end-to-end with your own keys
Terminate TLS in your customer's network at the upstream service or the ngrok agent. The ngrok cloud service only sees ciphertext.
Restrict traffic regions for data residency
Comply with data residency requirements by selecting the exact ngrok data centers used to relay your connections.
Safe multi-tenancy with least-privilege agent ACLs
Agents operate with only the permissions you explicitly define. ACLs control which endpoints they can create and ensure strict separation across customer environments.
All the boxes you need to check
Your customers have questions.
We have answers.
Send your customers a complete Q&A on how ngrok works and why it's secure.

Network failures are inevitable. Identify and recover from them automatically.
Reconnect automatically
You can't control your customer's network. That's why the ngrok agent runs in the background and heartbeats its connection to recover quickly after it sees connection reset by peer.
Alert on issues before customers notice
Publish tunnel status and connection events to your telemetry platform. When a connection drops, you'll know before your customer does.
High availability with agent redundancy
Run multiple agents in your customer's network and ngrok will balance connections among them. You'll stay connected even when a machine running one agent fails.
Stay online during region outages
Agents create secure tunnels to multiple regions of the ngrok cloud service. You won't go down when entire datacenters fail (cough, us-east-1, cough).
Built for multi-tenant SaaS at scale.
Ship the agent to every customer
The ngrok agent is a cross-platform, dependency-free binary pre-packaged for Docker, Kubernetes, Windows, Linux, and macOS.
import ngrok
Embed the agent directly in your application with an SDK for BYOC deployments where your software already runs in the customer environment.
Automate every customer
APIs for every feature, a Terraform provider for IaC, and bot users plus wildcard domains to automate per-customer onboarding.
White-label everything
Brand your URLs, agent connect address, and dedicated IPs with your own domains so customers associate the connection with your product.
Need to self-host ngrok?
Inquire about private edition“With traditional site-to-site VPNs, it would take us weeks or even months to securely connect our platform to our customers' networks. ngrok reduces the integration time to days.”
