What is remote support?

Remote support: definition

With remote support, an IT technician connects to the user’s device over the internet. The technician sees the screen and, if permitted, can control the mouse and keyboard, install programs, change settings and transfer files. The connection is encrypted, and communication usually runs in parallel by phone or chat.

There are two types. With attended access, the user starts the session and approves it with a code—ideal for spontaneous help. With unattended access, an agent is installed on the device so that IT can maintain servers or workstations without any action from the user, for example at night.

How a remote session works

The user reports the issue through the service desk. The technician asks for approval, the connection is established, and the problem is analyzed and solved. Afterward the session is closed and what was done is documented in the ticket. Most software problems can be sorted out within a few minutes this way—with no travel and no waiting time.

• Password resets, account lockouts and permissions
• Error messages in specialist software and office applications
• Installing and updating software
• Setting up email, printers and VPN
• Maintaining servers outside working hours
• Guidance and training directly on your own screen

Real-world example: a law firm working from home

A law firm with eight workstations has no in-house IT employee. A secretary working from home suddenly cannot access the firm’s software. She calls support and grants remote access, and after a short check the technician finds an expired certificate in the VPN client.

After about twenty minutes she can keep working—without anyone traveling to her. The same approach saves mid-sized companies with several locations trips and waiting time. Travel, scheduling and access to premises are eliminated entirely, the cost of the visit disappears, and the outage stays short.

Limits and security

Remote support only helps as long as the device is switched on, connected to the network and able to start. Faulty hardware, failed switches or a device without an internet connection require an on-site visit, which field service handles. The remote access itself must also be secured, because an unprotected entry point is a popular gateway for attackers.

Important safeguards are encryption, two-factor sign-in for technicians, approval by the user, logging of sessions and a data processing agreement, since remote maintenance can give access to personal data. Be wary of unsolicited calls from alleged “Microsoft employees”: grant remote access only to people you contacted yourself.

What companies should look out for

Define which tools are approved, who gets access and how sessions are documented. Avoid an uncontrolled mix of privately installed programs. Nano Concepts offers remote support as part of IT support and combines it with on-site visits where needed, so that problems are solved even when hardware has to be handled.
