Secure remote maintenance
External maintenance access is indispensable in many companies – at the same time, it poses a significant security risk. Service providers, administrators, and specialists need rapid access to critical systems, but insecure remote access, inadequate logging, or a lack of control mechanisms can jeopardize the availability and integrity of IT.
Our secure remote maintenance solution enables strictly controlled, auditable, and technically secure access to customer environments. Companies benefit from clearly defined access processes, strong authentication, secure VPN connections, and an infrastructure specifically designed for security-critical administration scenarios.
Why secure remote maintenance is crucial today
Many companies rely on external service providers and specialists to operate their IT systems. Maintenance work, especially on critical systems, often needs to be carried out quickly and reliably. At the same time, every external access point increases the attack surface.
The current remote maintenance page describes precisely this challenge: External support is necessary, but it brings risks to information security, availability, and traceability. Specifically mentioned are the lack of differentiation between legitimate and impermissible activities, legal problems arising from inadequate logging, and the need for professionally secured operation. :contentReference[oaicite:1]{index=1}
Secure remote maintenance therefore means more than just remote access. It requires, among other things, strong authentication, controlled connection paths, hardened administrative workstations, complete session logging, and a secure separation between the service provider and the customer network.
Our solution for highly secure remote maintenance
We provide a secure remote maintenance solution that allows external administrators and service providers to access authorized systems in a controlled manner. This page describes an administration portal accessible via a web browser, connected to customer networks via VPN, and capable of providing access to both Windows and Linux workstations. Login is secured with two-factor authentication. Additional features include session recording, whitelisting, hard drive encryption, restrictive access control, network segmentation, firewalls, IDS/IPS, and centralized permissions and patch management.
Our services include, among other things:
• Provision of secure remote maintenance workstations
• Connecting customer networks via controlled VPN connections
• Strong authentication for users and administrators
• Hardening of administration environments according to defined security specifications
• Logging and recording of administrative meetings
• Integration of additional protective measures such as firewalling, network segmentation, and malware protection
This creates a remote maintenance environment that combines technical security, traceability and operational practicality.
Secure remote maintenance is an important component of modern IT security architectures, especially in regulated and security-critical environments.
The current remote maintenance page refers to its adherence to BSI guidelines for cryptographic methods, TLS, IPsec/IKEv2, SSH, and VPN, as well as its operation in accordance with ISO/IEC 27001:2013 and BSI IT Baseline Protection. Additionally, it highlights compatibility with requirements from the BDEW white paper on secure information and communication systems. :contentReference[oaicite:3]{index=3}
This solution particularly supports requirements for:
• Secure administrative access to critical systems
• Traceability and logging of privileged activities
• Controlled network segmentation and strong encryption
• Technical security measures in regulated infrastructures
