WORK HISTORY
Technical Director @Commstec
Sheffield, GB
Responsible for setting and leading Commstec’s technical direction, with accountability for security, resilience, and governance across all client environments.I design and oversee managed infrastructure, endpoint security, and compliance automation services used by UK SMEs and public-sector organisations operating in complex or regulated contexts. My role is to ensure technology decisions align with business risk, operational reality, and regulatory expectations — not vendor trends.Day to day, I provide technical leadership to our engineering team, define service standards and architectures, and act as the senior escalation point for customers. Every solution we deliver is designed to be secure, supportable, and auditable — improving how organisations operate, not just how their systems run.
SKILLS
ABOUT MARC WALKER
With over 20 years’ experience across enterprise and public-sector IT, I design and run security-first managed IT services for organisations where resilience, trust, and operational reliability matter.My focus is on building and operating IT environments that are secure by default, resilient under pressure, and practical to run day to day in live, regulated environments.As Technical Director at Commstec, I’m accountable for technical strategy, security posture, and service standards across all customer environments, ensuring security is implemented, operated, monitored, and owned; not just advised on.I’ve worked with organisations ranging from small teams to multi-site enterprises across both public and private sectors. That experience shapes how we deliver managed services: standardised, well-documented, and engineered to withstand incidents, audits, and scrutiny without disrupting the business.A key part of our approach is being clear about risk. Where trade-offs exist, we surface them early, explain the impact, and build controls that are defensible in the real world; rather than quietly accepting risk in the background.Alongside client work, I lead and develop our engineering team, setting clear technical standards and encouraging ownership, curiosity, and continuous improvement. Strong services come from engineers who understand not just how systems work, but how businesses rely on them.If you need a security-first IT partner who will run your environment properly, take responsibility for outcomes, and help you stay resilient as your organisation grows; feel free to connect.
