NuSummit Cybersecurity collaborated with a global HVAC leader to achieve seamless Matter compliance by leveraging the DigiCert ONE platform for automated, scalable device identity management. To meet rigorous Matter certification requirements, the manufacturer needed a robust PKI strategy to issue Device Attestation Certificates (DACs) at high volume. DigiCert ONE provided a centralized, cloud-native architecture that replaced slow, traditional processes, enabling secure, cryptographic proof of compliance for every smart unit. This integration accelerated time-to-market while ensuring that devices could securely communicate across major home ecosystems. By embedding trusted digital identities into their supply chain, the manufacturer successfully scaled production without compromising secu
