IoT – Securing your Connected Devices and Systems

Does your security system actually cover connected equipment and systems?

The IoT is transforming IT, industrial, and urban environments: sensors, automation systems, cameras, terminals, mobile or embedded devices all involve Complex chains, often uncontrolled, often not updated.

It is therefore essential to map, secure, and maintain these components within a coherent cybersecurity strategy.

Our IoT offering assesses the security of information systems and infrastructure to reduce attack vectors. We map servers, architectures, and IT systems to identify unsecured areas. Securing connected devices and sensors is integrated into the overall IT and digital security strategy. Our audits identify exposed vulnerabilities and provide an action plan to secure the system and peripheral services. Risk analysis links technical flaws to business challenges to prioritize the remediation of sensitive data. Authentication controls and password management are strengthened to limit exposure to cyberattacks and hacking. We recommend security solutions (segmentation, EDR, secure gateways) tailored to your IoT infrastructure. Encryption and cryptography protect communications and guarantee the confidentiality of information transmitted by sensors. Our services measure the security level of information systems and define KPIs for the CIO and CISO. Securing systems includes server hardening, access management, and securing industrial and IT networks. We test resilience against cybercrime scenarios and simulate security incidents to validate operational response. Governance formalizes IT security policy and rules to ensure systems remain secure and traceable. Our target architectures isolate vulnerable equipment and prevent attacks from reaching the central information system. Risk management integrates scoring, remediation plans, and operational security measures to mitigate IT risk. Security audits and periodic reviews ensure that measures remain effective and that data is protected. We offer technical and organizational solutions to protect information security throughout the entire lifecycle. IoT monitoring and SOC detect abnormal behavior and accelerate response to security incidents. Our cryptography recommendations specify encryption in transit and at rest to limit data exfiltration. Securing your system includes automated patching, firmware maintenance, and the implementation of robust security measures. We help formalize a security policy and IT security policy tailored to the constraints of IoT. Secure architectures ensure that IT systems remain resilient to targeted cyberattacks. Our actions aim to make your equipment secure, protect network security, and safeguard data confidentiality. The goal is to integrate security by design, DevSecOps, and operational procedures to secure systems for the long term. Request an IoT diagnostic to assess your security posture, secure your connected devices, and protect their data.

Your challenges in the face of the IoT

Identify all exposed IoT terminals: business, industrial, user.

Assess the actual level of risk (vulnerabilities, lack of compartmentalization, network flaws).

Define a security-by-design model that is scalable and adapted to connected use cases.

Securing the flow between sensors → middleware → IS.

Ensure that suppliers, integrators and manufacturers comply with minimum safety requirements

Make your policy compliant with standards (ENISA IoT, ISO, ANSSI, ETSI, etc.).

Why is the IoT such a complex issue?

Objects deployed outside of radar (not in AD, unmonitored)

Specific industry protocols (BACnet, Modbus, Zigbee, MQTT...)

Heterogeneous and difficult to keep up-to-date (firmwares)

Concrete risks of rebound towards the internal or cloud IT system

Known attacks (botnets, camera hijacking, industrial sabotage)
