Let’s Connect

  • Network Segmentation and Isolation

    To improve OT Security and IoT Security, we implement comprehensive network segmentation. By isolating IoT and OT networks from IT networks, we reduce security risks and prevent lateral threat movement. Our solutions use VLANs, network control mechanisms, DMZs (Demilitarized Zones), air-gapped networks, and OT-specific firewalls and gateways to ensure secure communication.

  • Secure Remote Access

    Securing remote access to IoT and OT systems is crucial to prevent unauthorized access and protect system integrity. We utilize secure VPN connections, multi-factor authentication (MFA), and strict access control policies to meet the security needs of both areas, ensuring comprehensive access security.

  • Industrial Protocol Security

    Securing industrial and IoT-specific communication protocols is essential for ensuring data integrity and system reliability. Our measures include protecting protocols such as MQTT, CoAP, Modbus, and DNP3 with protocol firewalls, anomaly detection, and deep packet inspection.

  • Endpoint Protection for IoT Devices

    Our endpoint protection solutions effectively shield IoT and OT devices from cyber threats through specialized security measures. These include regular firmware updates, security agents, device certificates, as well as endpoint detection and response (EDR) solutions and application whitelisting for comprehensive endpoint security.

  • Operational Integrity and Monitoring

    Continuous system monitoring helps detect anomalies early and enables rapid response to potential incidents. With IoT- and OT-specific SIEM solutions, real-time monitoring, and machine learning, we ensure operational continuity and provide quick incident response capabilities.

  • Physical Security of IoT Assets

    Physical security measures prevent unauthorized access and tampering with IoT and OT components. These include access controls, tamper-proof enclosures, video surveillance, and the integration of physical and digital security solutions to provide comprehensive protection for physical infrastructure.

  • Incident Response and Recovery for IoT

    Our specialized incident response and recovery plans enable a quick and efficient response to security incidents in IoT and OT environments. This includes establishing dedicated incident response teams, conducting regular emergency drills, and developing detailed recovery plans.

  • Compliance with Industry Standards

    Adhering to recognized OT security standards and IoT security frameworks ensures regulatory compliance and enhances security in IoT and OT systems. We follow guidelines from the IoT Security Foundation, ETSI standards, the Industrial Internet Consortium, as well as standards like IEC 62443, BSI IT basic protection/CRITIS, and NIST SP 800-82.

  • Secure IT-OT Integration

    Our secure IT-OT integration approach promotes seamless and secure operations in both areas. By developing integrated security policies, secure communication channels, and coordinated incident response plans, we ensure a unified security approach between IT and OT systems.

    With a comprehensive focus on OT Security and IoT Security, we provide security solutions in Zurich and throughout Switzerland that protect the operation of IoT devices, industrial systems, and critical infrastructure. Our expertise in OT security vendors in Zurich, Switzerland, and continuous assessments supports you in effectively safeguarding both digital and physical assets.

FAQs

Have questions? We’ve got answers! Below are some of the most common questions our customers ask.

Network security protects traditional IT assets like servers, endpoints, and data flows, while IoT security zeroes in on connected devices—sensors, cameras, wearables—designed for scalability but often shipped with weak defaults. The challenge? IoT devices massively expand the attack surface and require tailored safeguards like device authentication, firmware hardening, and anomaly detection. Our expertise bridges both worlds, applying enterprise-grade security models to IoT ecosystems—ensuring your networks and smart devices remain hardened, resilient, and breach-ready against evolving cyber threats.

IoT endpoints demand more than basic antivirus—they need adaptive, layered defense. Protection typically includes device authentication, encrypted communication, real-time anomaly detection, firmware integrity checks, and policy-driven access control. Advanced endpoint solutions also apply AI-powered threat analytics to spot zero-day exploits before they spread. With deep expertise in IoT ecosystems, we ensure endpoints are not just secured but continuously monitored and hardened against evolving cyber threats, giving your connected infrastructure enterprise-grade resilience.

Continuous monitoring of OT and IoT systems means deploying real-time visibility tools that track device health, network traffic, and anomaly patterns 24/7. By instantly detecting irregularities—whether it’s a failing sensor, latency spike, or unauthorized access—issues can be resolved before they cascade into costly downtime. This proactive defense ensures uninterrupted operations, higher resilience, and safer workflows. With deep expertise in both OT and IoT security, we apply advanced monitoring frameworks that keep complex infrastructures running at peak reliability.

The safest way to isolate OT/IoT networks from corporate IT is through network segmentation with firewalls, VLANs, and zero-trust access controls. Critical OT/IoT assets should operate in dedicated zones, separated by secure gateways and monitored with advanced intrusion detection. Strong identity management, encrypted communication, and strict access policies further minimize risks. Our expertise ensures these layers are implemented with precision, balancing operational continuity and cyber resilience—so your business runs securely without exposing sensitive systems to IT-side threats.

Firmware updates and security agent patches for IoT/OT devices should never be “set-and-forget.” In practice, they must be applied as soon as vendors release critical security fixes and reviewed at least quarterly to mitigate evolving threats. High-risk or internet-exposed devices demand more frequent patching aligned with zero-day exploit cycles. Our expertise lies in establishing automated update pipelines, compliance-driven patch schedules, and proactive risk assessments—ensuring your IoT/OT infrastructure remains resilient, secure, and always audit-ready.
