How do you translate the Cyber Resilience Act into technical testing? Part II of our #CRA series follows a cheap IP camera, from STRIDE threat modelling and firmware analysis to compliance with IEC 62443-4-2. blog.compass-security.com/2026/06/cybe... #CyberSecurity #CyberResilienceAct #IEC62443

How do you prepare a product for the Cyber Resilience Act? Our latest article covers #CRA scope, product classification, threat modelling, technical security testing, and why we use IEC 62443 as an assessment framework. Part I of a two part series: blog.compass-security.com/2026/06/cybe...

Screenshot of an IEC 62443-4-2 security assessment report showing three overlapping report sections. The background page contains an overview table listing security requirements and the achieved Security Level (SL0 to SL4) for each requirement. In the foreground, a detailed table breaks down individual security controls, with cells color coded in green, yellow, and red to indicate the level of compliance or coverage across Security Levels SL1 through SL4. A gauge chart at the bottom visualizes the overall achieved Security Level, with the needle pointing toward the lower end of the scale. The layout resembles a professional cybersecurity assessment report summarizing compliance and maturity against IEC 62443-4-2 component requirements.
