Manufacturers are improving OT remote access, but third-party access governance still lags behind, says Secomea

Manufacturing operators are accelerating operational technology (OT) remote access capabilities to enhance production efficiency and workforce flexibility. However, this modernization push has created a governance asymmetry where security protocols for third-party vendor and contractor access have not kept pace with infrastructure expansion.

The research identifies a structural vulnerability in industrial ecosystems: while companies invest in remote connectivity, they are underweighting access control frameworks and permission auditing. This control gap exposes manufacturing facilities to elevated cybersecurity risk, particularly as supply chain partners require greater visibility into operational systems. The lag reflects competing priorities between digital acceleration and defensive posture.

For industrial operators, this signals an emerging need for governance standardization and vendor compliance frameworks. Organizations relying on third-party service providers—from equipment maintenance to engineering consultants—face heightened exposure if access policies remain reactive rather than preventive.

Sector implication: Industrials and manufacturing-adjacent technology vendors face demand tailwinds for access governance solutions, identity management tools, and compliance platforms. The sector remains in a structural transition phase where operational modernization outpaces security maturity, creating both risk and opportunity for enterprise software providers serving the industrial base.
