We Make Your Infrastructure Invisible
We secure your IT, OT, and critical infrastructure by eliminating all open ports and restricting access to authorized users only, turning your environment from exposed to invisible.
Unlike port knocking, VPNs, or SSH proxies, SSHepherd removes connectivity entirely for unauthorized users.
The Real Problem: Your Infrastructure Is Too Visible
Traditional perimeter security operates on a flawed assumption: that you can defend what attackers can see.
But today's threat landscape has fundamentally changed:
Attackers scan first, exploit later. Nation-state actors and organized crime groups run automated reconnaissance across millions of IPs daily, cataloging every open port and exposed service.
Breaches start with visibility. Once attackers identify an entry point, an SSH port, a VPN gateway, an exposed management interface, they have everything they need to begin credential attacks, exploit scanning, and lateral movement.
The question isn't whether your defenses can withstand an attack.
It's whether attackers can even find you in the first place.

How We Make Your Infra Invisible
We close all server ports by default and grant access only to verified, authorized users, whether your infrastructure runs on-premises, in the cloud, or hybrid.
Here's how it works:
Zero Open Ports
All server ports remain closed to the outside world. Local TCP connections open exclusively through the SSHepherd Control App/CLI, making your infrastructure invisible to scans and reconnaissance.
Identity-Based Access
Access is granted based on verified identity and device posture, not network location. No VPNs. No jump boxes. No firewall rule sprawl.
Complete Session Visibility
Every remote session is logged and viewable in the C3 audit interface, providing full visibility into privileged access activity for compliance and forensics.
Real-Time Session Control
Security teams can terminate rogue sessions instantly when detected, giving you immediate response capabilities without waiting for firewall updates or VPN reconfigurations.
Compliance by Design
Comprehensive session logging and audit trails support regulatory requirements including GDPR, HIPAA, PCI-DSS, and ISO 27001.
What You Achieve
Infrastructure That Attackers Cannot Find
External scans return nothing. Reconnaissance tools see no open ports, no services, no attack surface. Your servers simply don't exist to unauthorized users.
Zero Standing Privileges
No permanent VPN tunnels. No "always-on" jump box access. No firewall rules granting 24/7 connectivity. Access exists only when needed, for verified users, to specific resources.
Compliance Without Complexity
Meet GDPR, HIPAA, PCI-DSS, and ISO 27001 access control and audit requirements with comprehensive session logging, identity verification, and least-privilege enforcement.
Faster Incident Response
Real-time session monitoring and instant termination capabilities mean you can contain threats in seconds, not hours.
Lower Operational Overhead
Eliminate VPN management, firewall rule complexity, and jump box maintenance. Deploy in days across on-premises and cloud environments with software-only architecture.
Why SSHepherd Is Different
Most security solutions add more infrastructure: more VPNs, more firewalls, more jump boxes, more complexity. SSHepherd removes it.
