OT Security and Cyber Resilience: The New Constraint on SCADA Expansion

Greater connectivity has brought increased cyber risk to industrial environments.

Kaspersky's ICS-CERT detected malicious objects on 21% of industrial control systems (ICS) computers in Latin America in Q1 2025^{15Uno de cada cinco sistemas industriales en América Latina fue blanco de malware en 2025: Kaspersky}. Separate studies identify Mexico as a regional hotspot for targeted attacks, with hundreds of incidents per minute^{162023 Evolution of Cybersecurity Latin America and}.

Manufacturing faces significant exposure:

• A review found manufacturing accounted for 29.8% of all attempted cyberattacks against Mexican companies in 2024, the nation's most targeted sector^{17Manufacturing Was Most Attacked Sector in 2024: CyberSec Week}.
• Dragos's global analysis shows approximately 3,300 industrial enterprises suffered ransomware in 2025, up from 1,693 in 2024; manufacturing comprised about two-thirds^{18Significant Rise in Ransomware Attacks Targeting Industrial Operations - Infosecurity Magazine}.

Regulatory Landscape: Progress, but Gaps Remain for OT and SCADA

Mexico has advanced national cybersecurity strategy but gaps persist for OT:

• There is no dedicated federal cybersecurity law regulating industrial control and SCADA systems as critical infrastructure^{19Mexico’s Digital Growth Comes with Cybersecurity Challenges | Tripwire}.
• The National Cybersecurity Plan aims to chart a national course but reviewers highlight limited coverage of OT and SCADA needs; the plan acknowledges 16 major incidents and 155 ransomware victims since 2019^{20Mexico’s National Cybersecurity Plan}.
• Sectoral rules (such as in energy) are fragmented, and experts note unclear incident response obligations^{21Lack of Cybersecurity Laws Puts Mexico’s Energy Sector at Risk}.

For SCADA projects related to nearshoring, this creates dual pressures:

• Meet evolving local Mexican requirements, despite fragmentation.
• Align internally to international frameworks (NERC CIP, EU NIS2, ISA/IEC 62443) viewed as baseline standards by global customers.

Technical Security Priorities for SCADA in Mexico

Key best practices emerging in SCADA and OT environments include:

• Network segmentation and access control between IT/OT domains, with stringent remote and vendor access management.

• Continuous OT monitoring with passive detection/analytics for ransomware or unauthorized access.
• Incident response maturity including offline backups and tested recovery.
• Supply chain due diligence for all SCADA software and service partners, including those with remote roles.

Implementation Challenges on the Plant Floor

SCADA and automation growth faces real constraints in the field.

Legacy SCADA and Infrastructure Limitations

Many SCADA systems in Mexico's energy, manufacturing, and municipal sectors are legacy platforms. Global research shows these products typically lack security features and are difficult to retrofit securely without causing disruption^{22Insecure by Design in the Backbone of Critical Infrastructure}.

Basic infrastructure can also be a constraint:

• The 2022-2023 nearshoring surge exposed power system limitations, especially near the border, where electricity shortages constrained new manufacturing^{6México trabaja para solventar la escasez de electricidad que ancla su manufactura}.
• The electricity sector strategy targets 20-27 GW of new capacity by 2030 and expanded grid assets, with over US$23 billion committed, much tied to SCADA-enabled infrastructure^{23Mexican president aims for 27 GW of new capacity with large renewables share over next five years – pv magazine International}.

For OT teams, SCADA modernization is closely linked with power quality, capacity, and integration issues often beyond the automation engineer's direct influence.

Talent and Capability Gaps

Nearshoring intensifies demand for skilled industrial labor. BCG reports rising wages and worker shortages in key regions, notably near the border^{5The Shifting Dynamics of Nearshoring in Mexico | BCG}.

On the cybersecurity front:

• Fewer OT security specialists compared with IT security professionals.
• Underinvestment in ICS/OT security tools relative to sector risk^{19Mexico’s Digital Growth Comes with Cybersecurity Challenges | Tripwire}.

These constraints delay ambitious upgrade projects that require expertise in both control systems and OT cybersecurity.

Alignment with USMCA Partners

Plants serving North American organizations must meet U.S. and Canadian standards for SCADA and OT practices. This includes:

• Mapping controls to ISA/IEC 62443, NIST, and sector-specific frameworks.
• Demonstrating comprehensive incident response and access governance.
• Managing data to comply with cross-border legal and contractual requirements.

In practice, customer demands and international standards often set the operational benchmark when national regulation lags.
