Secure your operations. Protect your future.
Proactive, resilient, and business-aligned OT security programmes that protect industrial systems without risking availability or unplanned downtime.
OT Cybersecurity as a Service
Operational Technology and cyber-physical systems are the backbone of modern industrial operations. From manufacturing lines to energy distribution, water utilities, and critical infrastructure, today's networks are more connected than ever.
IT/OT integration and the Industrial Internet of Things unlock efficiency, but they also expose legacy industrial assets to sophisticated cyber threats. Shelef Technologies bridges industrial engineering and strategic risk management with a vendor-neutral service model built around how plants actually run.
Security that respects production
In industrial environments, availability and physical safety are non-negotiable. We design defences around production schedules and operational constraints - never requiring unplanned downtime as a default assumption.
Assessments, roadmaps, and controls are mapped to the frameworks auditors, insurers, and regulators expect, including ISA/IEC 62443, NIST SP 800-82, NIST CSF, NERC CIP, and NIS2.
Full-lifecycle OT security offerings
We meet you wherever you are on the industrial security journey, with a programme that scales with operations.
-
01 - Discovery & Strategic Alignment Map industrial assets, control-network boundaries, and IT/OT convergence points. Model threats against physical process impact and sector-relevant threat landscapes. Set objectives mapped to IEC 62443, NIST SP 800-82, NIS2, and regional regulation.
-
02 - Risk & Maturity Assessments Identify critical PLCs, HMIs, SCADA, and industrial databases. Assess people, process, and technology maturity. Analyse vendor remote access and supply-chain exposure. Deliver a scored risk register leadership can act on.
-
03 - Governance Model Definition Define roles and accountability across IT and OT. Establish trackable metrics and KPIs for maturity and board reporting. Build an audit-ready documentation package for regulatory evidence.
-
04 - Pragmatic Security Roadmaps Realistic, step-by-step plans - not 200-page reports that sit unused. Prioritise initiatives by risk, budget, and production constraints. Schedule milestones, costs, and IT/OT integration with corporate cyber governance.
-
05 - Implementation & Continuous Support Advisory on segmentation, secure remote access, and system integrity. Joint IT/OT training for security teams and field engineers. Recurring posture health checks as threats and operations evolve.
Why this service works
Independent OT-first advisory that leadership can fund and operations can execute.
OT-first approach
Availability and physical safety come first. Controls are designed around production, not around generic IT playbooks.
Framework mapping
ISA/IEC 62443, NIST CSF, NIST SP 800-82, NERC CIP, and NIS2 - the language auditors, insurers, and regulators already use.
Pragmatic results
Roadmaps that are fundable, realistic, and executable by your teams - with immediate operational value, not shelfware.
Vendor-independent
Unbiased advisory with no product resale obligation. Recommendations serve your environment, not a sales pipeline.
How the programme runs
Ready to secure your operations? Many industrial security gaps start with weak visibility or unoptimised configurations. Start with a conversation - no product pitch.
