THE CHALLENGE
Why Traditional Remote Access Fails in OT
HOW IT WORKS
WALLIX replaces risky direct connections with a controlled gateway. Remote users connect to WALLIX, authenticate securely, and access only the specific systems they’re authorised to use – with every action recorded.
Users connect to the WALLIX gateway – not directly to OT systems. Multi-factor authentication verifies their identity before any access is granted. Integration with your existing identity provider means no separate credentials to manage.
After authentication, users see only the systems they’re permitted to access – not the entire network. Access policies determine who can reach which systems, when, and for what purpose.
WALLIX establishes the connection to the target system on behalf of the user. Credentials are injected automatically – users never see or handle passwords for critical systems. The session flows through the gateway, not around it.
Every action during the session is recorded for audit and investigation. Real-time monitoring allows security teams to observe sessions and intervene if needed. When the work is done, the session ends cleanly.

| YOUR RISK FACTORS | WITHOUT WALLIX | WITH WALLIX |
|---|---|---|
| Network Exposure | ❌ VPN exposes full network | ✅ Access to specific systems only |
| Authentication | ❌ VPN credentials only | ✅ MFA + identity verification |
| Session Visibility | ❌ No insight into actions | ✅ Full session recording |
| Credential Handling | ❌ Users know/share passwords | ✅ Automatic credential injection |
| Assess Duration | ❌ Permanent until revoked | ✅ Time-limited sessions |
| Incident Investigation | ❌ Limited logs, no context | ✅ Video-style playback, full audit |
CAPABILITIES
The technical foundations that enable secure remote access to OT environments.
Enforce MFA for all remote access. Support for TOTP, push notifications, hardware tokens, and integration with existing identity providers.
Native support for RDP, SSH, VNC, Telnet, and HTTP/HTTPS. Connect to Windows systems, Linux servers, network devices, and web interfaces.
Capture every session with video-style playback. Keystroke logging, command capture, and OCR for text extraction from graphical sessions.
Clustered deployment for continuous availability. No single point of failure for critical remote access infrastructure.
FAQ
Does this replace our VPN entirely?
For privileged access to OT systems, yes. WALLIX provides a more secure alternative that gives you granular control and visibility that VPNs cannot offer. Some organisations maintain VPN for general network access while routing all OT privileged access through WALLIX.
What happens if the WALLIX gateway is unavailable?
WALLIX supports high-availability deployment with automatic failover. For planned maintenance, sessions can be gracefully migrated. In true emergencies, break-glass procedures provide documented alternative access paths.
How does this affect user experience for remote workers?
Users authenticate once to the WALLIX portal and see all systems they’re authorised to access. Connections launch with a single click – no need to remember separate credentials for each system.
Can we integrate with our existing identity provider?
Yes. WALLIX integrates with Active Directory, LDAP, RADIUS, and SAML identity providers. Users authenticate with their existing corporate credentials.
What about performance for graphical applications like HMIs?
WALLIX uses optimised protocols for graphical sessions. RDP and VNC connections are hardware-accelerated where available.
