IoT Remote Access. Securely Connect to Any Device, Anywhere

Yes. SocketXP creates only an outbound connection to our cloud gateway. All connections use mutual TLS (mTLS) authentication and end-to-end SSL/TLS encryption. SocketXP uses a Zero-Trust model — no inbound firewall ports are ever opened. Only authenticated and authorized users, after a successful SSO OIDC login, can connect to devices.

Traditional reverse tunneling tools such as Ngrok, Pinggy, and LocalXpose typically expose a publicly reachable open port in their cloud server that forwards traffic to your device. SocketXP takes a private remote access approach. Your IoT device makes an outbound, authenticated connection to the SocketXP Cloud Gateway, while a local proxy on your PC or laptop provides a private endpoint for remote access. No publicly reachable open ports.This lets you access devices behind NAT, firewalls, and CGNAT without directly exposing SSH, HTTP, MQTT, or other service ports to the public internet, making SocketXP a better fit for security-sensitive IoT and industrial environments.

Yes. SocketXP is purpose-built as a VPN-free IoT remote access solution. Traditional VPNs require you to open inbound firewall ports, manage a VPN server, and route all device traffic through a central gateway — creating a single point of failure and a broad attack surface. SocketXP uses device-initiated outbound SSL/TLS tunnels instead, so no firewall ports are ever opened on the device network. Each device gets its own isolated secure tunnel, making it far simpler to manage and more secure than a shared VPN. It also works over carrier-grade NAT (CGNAT), Starlink, and 4G/5G cellular networks where traditional VPNs typically fail.

Install the SocketXP agent on your IoT device. The agent creates an outbound SSL/TLS reverse proxy tunnel to SocketXP's cloud gateway — no port forwarding or firewall rule changes needed. You can then SSH, VNC, or RDP into the device from anywhere using the SocketXP web portal or standard clients.

SocketXP supports SSH, VNC, and RDP for full remote access and control, plus HTTP/HTTPS for reaching IoT web apps and dashboards. For file operations, SFTP and SCP are supported over the same secure tunnel. All protocols run over an outbound SSL/TLS connection, so no inbound ports are ever opened on the device.

A reverse SSH tunnel is an outbound connection from a device to a remote server that allows traffic to flow back in the opposite direction — enabling remote access without opening inbound firewall ports. SocketXP's agent creates an SSL/TLS-encrypted reverse proxy tunnel from each device to the SocketXP cloud gateway, making the device reachable from anywhere without any router or firewall reconfiguration.

Yes. SocketXP provides remote SSH access to Raspberry Pi without any port forwarding. Install the SocketXP agent on your Raspberry Pi and register it with the platform. SocketXP creates a secure outbound tunnel so you can SSH into the Pi from anywhere, even when it is behind a home router, firewall, or cellular network.

Yes. SocketXP includes a built-in web-based SSH terminal in the portal. Open a browser, go to your device in the SocketXP dashboard, and click Connect — no SSH client installation needed. The same portal provides a web-based SFTP file browser for remote file transfers.

Yes. SocketXP supports SFTP and SCP for remote file transfer. You can use the built-in SFTP browser in the SocketXP web portal, or any third-party SFTP client like FileZilla, WinSCP, or the OpenSSH scp command, to upload and download files securely over the SocketXP tunnel.

Yes. The SocketXP web portal is mobile-responsive, so you can SSH into or monitor your IoT devices from a smartphone or tablet browser.

Yes. You can add multiple team members to your SocketXP organization and assign role-based permissions (admin, member, viewer) controlling which devices or device groups each person can access. This makes it easy for an ops team to share fleet management without giving everyone full account control.

Yes. You can invite external users — customers, field engineers, or vendors — to your SocketXP account and grant them access to specific devices or device groups using RBAC. Access can be time-limited and revoked at any time, giving you full control over who can connect and when.

Yes. SocketXP is built for large-scale fleet deployments and scales to 100,000+ devices. Each device runs a lightweight agent that establishes a persistent outbound SSL/TLS tunnel — no open ports, no VPN, and no router configuration needed. Engineers can SSH, VNC, or RDP into any individual device, or run commands and push OTA updates across the entire fleet simultaneously.
