Common pitfalls when buying ICS security services
ICS security buyers often over-index on assessment deliverables and under-specify the conversion of findings into engineering implementation and response operations. Another frequent failure mode comes from selecting a delivery model that cannot operate within plant access constraints or governance timelines.
The mistakes below focus on mismatches between what providers deliver and what stakeholders must run after the engagement ends.
Treating an OT assessment report as the end of the work rather than a controlled input to remediation and response coordination
Buyers should require delivery that explicitly connects assessments and architecture work into remediation planning and incident response artifacts, since PwC integrates those steps and Optiv turns assessment outputs into site-ready playbooks.
Choosing a services-led governance or consulting model without planning for coordination load across plants and corporate functions
Program buyers should budget coordination time and stakeholder access for large deployments, because Deloitte notes that large programs can require extensive coordination and Booz Allen Hamilton flags stakeholder coordination and site access constraints for large engagements.
Assuming boundary and remote access review outcomes will automatically map to engineering hardening execution
Buyers should insist on actionable engineering outputs for jump path and industrial DMZ control changes, since NCC Group produces OT-focused hardening plans derived from boundary security reviews.
Expecting continuous security workflows and protocol-aware monitoring from providers whose primary differentiation is program delivery
Buyers should validate automation and monitoring scope early, because Coalfire describes limited automation and API surface due to services-led delivery and Guidehouse is less suited for teams seeking a single protocol-aware monitoring product.
Under-scoping the OT tuning work required to align detections with plant traffic patterns
Buyers should plan for OT-specific tuning effort when selecting IBM, since its ICS-specific tuning takes time to align detections with plant traffic and requires careful project scoping for OT segmentation and remote access controls.
