Remote PAM for OT & critical infrastructure

Remote maintenance for critical infrastructure – without opening your network

Your systems require maintenance by external vendors – but every access point is a risk to availability and security. VISULOX allows service providers to work on OT and legacy systems without ever gaining direct access to your network. Controlled, time-limited, and fully recorded.

How can I allow vendors to perform maintenance without putting the facility at risk?

OT environments rely on external maintenance but are rarely built for secure remote access. Legacy protocols, permanent vendor access, and flat networks turn every maintenance task into a risk. At the same time, NIS2/BSIG require verifiable control over the entire supply chain.

Protocol break

no direct network access to OT.

Just-in-time

Vendor access only during maintenance.

100%

recorded, auditable sessions.

Isolation

Maintenance without a direct line into your facility

External users work via a browser in a segregated zone. Protocol breaking ensures there is never a direct connection to the OT infrastructure.

Gateway architecture without direct network access

Connections via RDP, SSH, VNC, HTTPS

Securing IT and OT systems together

No VPN, no flat networks

Protokollbruch zwischen externem Techniker und SPS, SCADA und HMI

Just-in-time

No permanent access for external technicians

Access is created for a limited time and a specific purpose. No standing privileges for maintenance companies, no forgotten access.

Just-in-time access, zero standing privileges

Grant and revoke access with a click

Multi-factor authentication

Break-glass for emergencies

Zeitlich begrenzter Wartungszugang statt dauerhaftem Herstellerkonto

Control

Never leave external personnel unattended near critical systems

You can see who is working on what in real time and intervene at any moment. Every session is recorded for audit purposes.

Duncan K.

Security Analyst

VISULOX enables the management of information security through the privileged access control of users to various infrastructures with centralized management.

Robert F.

IT Manager

VISULOX works flawlessly, and the IT support is exceptionally reachable in emergencies. Moreover, the team also assists with other concerns, even if they are not directly related to VISULOX.

Gerd H.

Head of IT-Services

We can be sure that our R&D data is accessed exclusively by us. VISULOX gives us the assurance that external service providers are never 'unattended' and that no one can access critical information or, in the worst case, even share it.

Alois O.

CISO

Secure access to IT infrastructures can be presented very transparently. The system operates stably, even with over 1000 users. Our implementation of ISO 27001 is significantly supported, especially for large infrastructures.

Matt C.

IT Director | Automotive

VISULOX monitors service provider activities across servers – privileged multiple accounts  are eliminated. Together with amitego, we have developed a transparent, auditable control system that precisely documents who did what and when.

Andreas B.

SOC Specialist

Highly powerful, mature, and secure for privileged remote access by external service providers. First-class support and a forward-thinking development team at amitego. We are in close, ongoing contact with the vendor and can actively contribute to the product's evolution. Customer requests are addressed promptly.

FAQ

Antworten auf die häufigsten Fragen aus dem Finanzsektor.

What is Remote Privileged Access Management (Remote PAM) with VISULOX?

Remote Privileged Access Management (Remote PAM) controls and protects privileged access to IT systems from remote locations — by administrators, external service providers, or partners. VISULOX implements this approach consistently: access is managed centrally, granted on a time-limited basis, uniquely assigned to an individual, and fully documented. Direct connections to the target infrastructure are technically prevented. This ensures control, traceability, and security at all times.

How does VISULOX differ from classic VPN or PAM solutions?

Conventional VPN solutions grant broad network access without fine-grained control. Classic PAM solutions are often complex, costly, and designed primarily for internal users. VISULOX combines the advantages of both approaches: a gateway architecture without direct network access, time-limited just-in-time access, complete session recording, and an agentless architecture. The result: maximum control with minimal administrative effort — purpose-built for secure external access.

How does VISULOX support a Zero Trust strategy?

VISULOX implements Zero Trust consistently: no user has standing access rights — permissions are granted only when needed, based on the least-privilege principle (just-in-time access). Direct network connections are technically prevented through a protocol break. Every session is fully recorded and uniquely assigned to a single individual. This creates a zero-standing-privileges model that also securely integrates external service providers and partners.

Why does VISULOX have a lower total cost of ownership (TCO)?

VISULOX is ready to use within a few days — without complex implementation projects and without changes to endpoints. Its agentless architecture significantly reduces maintenance effort. Licensing by concurrent users avoids hidden costs. Together with integrated German-language support and the avoidance of costs from security incidents, VISULOX demonstrably reduces complexity and operating costs.

Is VISULOX suitable for enterprise environments?

Remote Privileged Access Management (Remote PAM) governs and secures privileged access to IT systems from remote locations — by administrators, external service providers, or partners. VISULOX implements this approach consistently: access is granted centrally, time-limited, uniquely assigned to an individual, and fully documented. Direct connections to the target infrastructure are technically prevented, ensuring control, traceability, and security at all times.
