Device security for connected industrial products

Industrial products can stay in the field for decades. We help manufacturers secure connected devices, address security gaps and meet EU CRA and IEC 62443 requirements, from assessment to implementation.

Secure firmware updates in the field

We develop secure firmware updates for over-the-air and wired delivery, with authenticity checks to prevent invalid or unauthorized firmware from being installed.

Device identity and access control

We establish device identity using certificates and TPM-based keys, alongside access management for device configuration and remote service.

How we work

From gap analysis to working software

We do both the analysis and the engineering, so the findings don't sit in a report waiting for someone to implement them. CRA and IEC 62443 assessments help identify security gaps, while secure firmware updates and device identity are among the ways we address them.

Step 1
Assess

We examine your product architecture, security risks and applicable requirements to establish what needs attention.
Step 2
Prioritize

We balance security requirements, cost and product constraints. Where feasible, we work within the existing hardware to avoid redesign.
Step 3
Implement

Our engineers build what's missing: secure boot, signed and encrypted firmware, secure OTA, access control and protected device-to-cloud connections.
