What is L&M Cyber Security?
Cybersecurity from strategy to operation
L&M Cyber Security B.V. provides professional IT and OT security and project management services covering implementation, management, monitoring and operational support.
We help organizations strengthen their security posture, improve cyber resilience and align security controls with standards and regulatory requirements such as ISO/IEC 27001, IEC 62443 and NIS2.
Our security professionals combine cybersecurity expertise with hands-on implementation and project experience. This means our work does not stop at recommendations: we help customers implement and embed security improvements in their organization.
What we do
Operate, detect, comply, deliver.
Four capabilities that share findings, tooling and context — with security assessments available as a standalone engagement.
Security Operations
Manage and continuously improve your daily cybersecurity environment.
Day-to-day operation of your security controls — monitoring, vulnerability management, access control and endpoint protection — run as a managed service or alongside your own team.
Explore Security OperationsThreat Monitoring & Incident Response
Detect cyber threats early and respond effectively when an incident occurs.
Threat monitoring, incident handling and recovery planning — including playbooks, disaster recovery plans and cyber recovery exercises that make the response repeatable.
Explore Cyber ResilienceGovernance, Risk & Compliance
Translate standards, risks and regulatory requirements into practical security controls.
ISO/IEC 27001 and NIS2 readiness, IEC 62443 implementation, risk assessments and the policies, controls and reporting that stand up in an audit.
Explore Governance & ComplianceSecurity Delivery
From cybersecurity roadmap to successful implementation.
Management of cybersecurity projects from planning through implementation and operational handover, including architecture, specialists and supplier coordination.
Explore Security DeliveryIT & OT Security

IT Security
Security for identities, endpoints, servers, networks, cloud environments and business applications.
OT Security
Security for industrial systems, OT networks, assets and critical infrastructure.
IT/OT Integration
Secure connectivity, network segmentation, remote access and access control between IT and OT environments.
Cyber Resilience
Incident response, recovery planning, cyber exercises and business continuity.

Insights
Practical cybersecurity insights
Insights, guidance and practical perspectives on IT and OT security, cyber resilience and regulatory requirements.
Compliance
NIS2: what does it mean for your organization?
NIS2 widens the range of organizations in scope and puts named accountability on management. Here is how to work out whether it applies to you, and what to do first.

Compliance
ISO/IEC 27001: from gap assessment to implementation
A gap assessment tells you where you stand. It does not tell you what order to fix things in — and that ordering decides whether the programme finishes.

OT Security
IEC 62443 and OT cybersecurity
Industrial environments do not tolerate IT security practice applied unchanged. IEC 62443 exists because the priorities are genuinely different.
