Adnan Beciri

Cybersecurity Engineer IT/OT

I help critical infrastructure teams anticipate, measure, and mitigate cyber risk. My background spans offensive security, industrial control systems, and building security programs that work under operational constraints.

Profile

My work centers on protecting operations that cannot fail. I partner with plant engineers, site leads, and executive stakeholders to define threat models, validate controls, and implement practical security roadmaps.

I bring a balanced offensive and defensive perspective: years of penetration testing and red teaming combined with architecting resilient systems for regulated industries.

Operating Principles

  • Lead with context first. Understand the business process and constraints before prescribing controls.
  • Deliver measurable outcomes. Every engagement ends with metrics that track resilience over time.
  • Invest in enablement. Documentation, workshops, and tabletop exercises turn improvements into habits.
  • Build for the long game. Favor changes that scale, automate, and reduce toil for operators.

Engagement Highlights

  • Designed an OT security reference architecture adopted across 12 production plants within one fiscal year.
  • Created a red team maturity roadmap that guided clients from pilot exercises to continuous purple teaming.
  • Advised on managed detection and response onboarding, including log strategy, playbooks, and success metrics.

Speaking and Writing

  • SecCon Europe 2024: Securing converged networks without halting production.
  • ICS Village Workshop: Rapid threat modeling for OT operators.
  • Blog series: Practical playbooks for bridging SOC and plant operations.

Community and Mentoring

I actively contribute to local security meetups and mentor practitioners entering the OT security space. Recent efforts include building lab environments for training and releasing open source tooling for asset profiling.
