Legacy systems create integration hurdles
Many manufacturers still rely on OT equipment that was never designed to connect to modern IT networks. Industrial gateways, edge computing, and cloud platforms help bridge this gap by connecting legacy systems to modern infrastructure. Secure remote access solutions such as TeamViewer Tensor allow IT teams to support OT environments without disrupting production.
Many organizations still rely on VPNs or homegrown access solutions, but these often lack the scalability, security, and auditability required in today's industrial environments. Purpose-built remote connectivity has become the new standards.
Cybersecurity risks increase as IT and OT environments converge
Connecting IT and OT expands the attack surface, particularly when legacy OT systems lack modern security controls. In manufacturing, a breach can do more than expose data. It can halt production, damage equipment, and create safety risks.
Effective IT/OT cybersecurity requires:
- Network segmentation to isolate OT environments
- Zero trust architecture to verify every user and device
- Identity and access management (IAM) to enforce least-privilege access
- Compliance frameworks such as IEC 62443 and NIST
Vendor and contractor access is difficult to secure
External vendors often require remote access for support and maintenance. Traditional VPNs frequently provide broader access than necessary, increasing security risks.
Modern remote connectivity solutions restrict access to specific devices and provide visibility, audit trails, and role-based permissions. This helps organizations maintain security without disrupting operations.
IT and OT teams need to work together
OT teams prioritize keeping production running, while IT focuses on security. Successful IT/OT convergence requires solutions that support both goals.
This means:
- Giving engineers control over equipment access
- Embedding security without disrupting daily operations
- Treating OT teams as partners in the integration process
When both teams align around shared goals, collaboration replaces friction and security becomes easier to adopt.
Justifying the ROI
IT/OT integration requires upfront investment, but a Boston Consulting Group study found that companies implementing IT/OT integration typically achieve an average ROI of 20-30% within three years, driven by reduced downtime, improved resource utilization, and greater operational efficiency. Standardized access controls can also strengthen regulatory compliance.
