MANUFACTURING CYBER RISK STORY #5
The Remote Risk: Why Remote Access Can Quietly Expand Manufacturing's Attack Surface
Remote access risk grows when too many tools, weak authentication and limited session visibility create trusted pathways into manufacturing environments.
Remote Access Overview
Remote access is now part of everyday manufacturing operations. IT teams use it to troubleshoot, vendors use it to maintain equipment and engineers use it to support distributed sites. Leadership depends on it to keep production moving without waiting for someone to be physically on-site. That operational value is exactly what makes remote access risky.
In many environments, remote access is not one tool or one tightly governed workflow. It is several tools layered over time, each added for a different support need, vendor relationship or operational exception. What starts as convenience becomes complexity and complexity becomes exposure. The findings behind this story showed a clear pattern: manufacturers often rely on multiple remote access tools per environment, including outdated software, weak authentication practices and inconsistent session monitoring. In some cases, the tools designed to keep operations available also create some of the easiest paths into the environment.

REMOTE ACCESS GOVERNANCE
Why remote access needs stronger control.
Manufacturers need remote access to support uptime, troubleshoot systems and maintain distributed operations, but 24/7 visibility does not require 24/7 access. The safer model is structured remote access with clear ownership, strong authentication, restricted privileges and compliance-oriented monitored sessions. Remote access should help keep production moving without creating invisible entry points no one is actively governing.
This is why remote access should be treated as a security function, not an informal convenience. The issue is not whether support is internal, outsourced or shared. It is whether remote access is documented, updated, authenticated, monitored and reviewed consistently over time.
WHAT THE FINDINGS REVEALED
How remote risk compounds over time.
The findings showed a recurring pattern: every manufacturer needs remote access, but many environments accumulate too many remote pathways over time. In some cases, environments had 3, 4 or even 5 different remote access tools in place, including outdated versions of ScreenConnect, TeamViewer and similar platforms. Other environments showed weak authentication practices and no centralized logging of remote sessions.
That combination creates a dangerous dynamic. When a tool is vulnerable, authentication is weak and no one can reconstruct session activity, a support method becomes an attack path. What begins as convenience often becomes complexity, and complexity becomes exposure.
WHERE REMOTE RISK SHOWS UP
The most common remote access gaps.
Remote risk tends to appear in a small number of repeated patterns. Too many remote access tools create unnecessary pathways to maintain and secure. Outdated remote access software can become a direct entry point when vulnerabilities are left unaddressed. Weak authentication, shared credentials and missing MFA make trusted tools easier to misuse. A lack of centralized logging makes it harder to investigate suspicious activity or confirm what happened during a remote session.
Third-party access can increase that risk when vendors, OEMs, MSPs or integrators operate outside the same standards used internally. Any outside party with remote access should follow the same expectations for approved access methods, MFA, limited privileges, named accounts, logged sessions and documented business justification at minimum.
WHAT MANUFACTURERS SHOULD DO NEXT
How to reduce remote access risk.
Manufacturers can reduce remote risk by standardizing approved tools, requiring MFA for all remote sessions, logging session activity centrally, restricting vendor access to only what is necessary and reviewing access on a recurring basis. Remote support platforms should be kept current, unused accounts should be removed and access pathways should be clearly documented.
The most important step is establishing governance that can be applied consistently. Whether the model is co-managed, fully managed or internal, the organization should be able to answer clear questions about who owns policy, which tools are approved, who reviews accounts, whether sessions are logged, how quickly tools are patched and how exceptions are handled. Stronger manufacturers treat remote access as a security boundary because it sits directly at the intersection of uptime, trust and cyber risk.
COMMON QUESTIONS
What You Can Do Next
Why is remote access a cybersecurity risk in manufacturing?
Remote access is essential in manufacturing because it supports troubleshooting, vendor maintenance and distributed operations. But when it is not governed carefully, it can create trusted entry points into the environment. The risk grows when tools are outdated, authentication is weak or session activity is not monitored.
What did the remote access findings reveal?
The findings showed that remote risk often builds over time through convenience and exception handling. Some manufacturing environments were using three to five different remote access tools, including outdated versions of support software, weak authentication practices and no centralized logging of remote sessions. Together, those gaps can turn support tools into attack paths.
Where do remote access risks show up most often?
Remote access risk usually appears in a few common areas: too many tools, outdated software, weak passwords or missing MFA and limited session visibility. Third-party access can also become a blind spot when vendors or support partners are not held to the same security standards as internal teams.
How can manufacturers reduce remote access risk?
Manufacturers can reduce remote risk by standardizing approved tools, requiring MFA for all remote sessions, logging activity centrally and limiting vendor access to only what is necessary. They should also remove unused accounts, keep remote tools current and review access regularly to make sure it still serves a business need.
Why should leaders treat remote access as a security boundary?
Remote access sits at the intersection of uptime, trust and cyber risk. The same tools that help keep operations moving can also provide broad access to critical systems if they are not controlled well. That is why leaders should measure remote access not only by how well it supports the business, but also by how safely it does so.
WHAT IT MEANS
Treat remote access like a security boundary.
Reduce risk by strengthening authentication, limiting tool sprawl and improving visibility into every remote session.
