OT Security OPERATE Services
Maintaining resilience, compliance, and continuous improvement over time
The challenge
Security isn’t a one-off project — it’s an ongoing commitment. You need to ensure that systems are continually monitored, maintained, and improved. That can be a challenge for many companies.
The solution
Our OPERATE services are designed to keep your investment working for you. By embedding monitoring, governance, and ongoing improvement, organisations achieve long-term resilience and confidence. It ensures security is not just built but sustained as a competitive advantage.

Operating Model Design & Implementation Support
Effective OT security relies on clear ownership, repeatable processes, and reliable reporting. We design a fit-for-purpose operating model that defines roles, workflows, service levels and interfaces across OT, IT and the business, then help you roll it out.

OT Security CISO-as-a-Service
We act as your fractional OT security leader – owning the cadence of risk reviews, compliance updates, programme steering, and executive communication – backed by hands-on specialists when needed.

OT Security Advisory
Pre-purchased advisory days you can draw down flexibly for strategy input, architecture/design reviews, policy red lines, investment cases, supplier evaluations, or incident counsel.

Embedded OT Security Practitioners
We place vetted practitioners into your team to accelerate delivery, backfill roles, or stand up new capabilities while transferring knowledge to your staff.

OT Security Staff Augmentation
The Staff Augmentation service provides agility and certainty. You gain the ability to scale up or down in line with programme demands, ensuring deadlines are met and risks are controlled.
