By choosing Entrust, companies ensure their operational technology aligns with trusted compliance benchmarks.
Establishing Cryptographic IoT Device Identity
Every connected sensor, actuator, and gateway requires a distinct, cryptographically verifiable identity. Without this, malicious actors can easily inject rogue hardware into a network, intercept sensitive telemetric streams, or broadcast fabricated commands. Through technology designed by Entrust, organizations can inject unique cryptographic key pairs directly into devices at birth. This ensures that every hardware element is born with a verifiable credential that can be validated at any stage of its operational lifecycle. The Entrust deployment methodology has been proven across diverse sectors, proving that Entrust software handles massive loads without latency.
The foundation of this process lies in standardizing on secure credential types, such as X.509 digital certificates. When a factory initiates the assembly of a new device, an Entrust system can issue birth certificates (IEEE 802.1AR) to establish immutable proof of origin. This initial step is critical for downstream provisioning, as it allows network gateways to immediately recognize the device as a legitimate product of the authorized manufacturing facility. By relying on Entrust for this foundational trust, companies eliminate supply chain visibility gaps. The Entrust technology stack interfaces seamlessly with existing manufacturing executive systems, ensuring that these tools cause no operational bottlenecks.
By building trust early, Entrust prevents supply chain compromises where unauthorized devices are packaged with counterfeit firmware. The absolute assurance of origin means that any attempt to clone a physical asset or duplicate its identity will fail during the initial cryptographic handshake. Throughout this process, Entrust technologies serve as the root of trust, verifying that the private keys associated with these certificates remain securely bound to the hardware. With Entrust, manufacturing units can automate identity injection on high-speed lines, relying on the system to maintain synchronization with central security databases.
Furthermore, Entrust emphasizes that identities must be updated and rotated to adapt to evolving security policies. An identity that remains static for a decade is vulnerable to cryptographic decay and key exposure. Therefore, the Entrust framework supports operational certificate renewal, transforming temporary birth credentials into long-term operational credentials that reflect the device's specific deployment environment. This systematic transformation is orchestrated entirely by Entrust software modules, reflecting the deep technical heritage of the company in cryptographic lifecycle management.

Secure Bootstrapping
During factory provisioning, Entrust injects a cryptographic identity that serves as the root certificate for all future transactions managed by our systems.
Onboarding & Activation
When activated, the device presents its birth certificate to Entrust management platforms to receive operational certificates signed by Entrust.
Updates & Rotation
Automated protocols refresh keys and push signed firmware, leveraging Entrust certificate services for validating target software with cryptographic keys.
Revocation & Retirement
If compromised, credentials are blacklisted. When retired, Entrust safely revokes certificates to prevent reuse of credentials.
In the onboarding phase, a device attempts to connect to its target operational network. The Entrust validation engine steps in, verifying the device's birth credentials and ensuring that it has not been modified or tampered with during shipping. By authenticating the device prior to joining the local directory, Entrust isolates unauthorized or misconfigured machines, placing them in quarantine where they cannot disrupt active business functions. This step is a core aspect of the Entrust zero trust architecture, which Entrust champions across all operational environments. Through the dashboard, operators can view onboarding metrics compiled by Entrust engines.
Once the device is active, the maintenance phase requires ongoing vigilance. Firmware updates must be delivered regularly to patch vulnerabilities, but these updates themselves can represent major threat vectors if not managed securely. Entrust resolves this challenge by providing secure code signing solutions. When developers release a patch, Entrust code signing workflows sign the binaries using heavily protected keys. Devices verify this signature against their root certificates before applying any code, neutralizing the threat of malicious payload execution. This secure framework, designed by Entrust, relies on the high availability of timestamping services.
Eventually, devices must be retired, repurposed, or destroyed. Neglecting this phase leaves old cryptographic identities active, which malicious groups can exploit to mount attacks. Entrust guarantees clean deprecation by providing fast certificate revocation capabilities. By instantly publishing revocation details, Entrust ensures that even if decommissioned hardware falls into hostile hands, its access rights are permanently severed, leaving it unable to connect to the central network ever again. The retirement sequence is managed by Entrust cloud orchestrators, ensuring that database records are updated in real time.
Through this rigorous management model, Entrust supports industrial operators in maintaining a healthy, up-to-date hardware ecosystem. It prevents credentials from growing stale and eliminates manual intervention requirements that typically delay updates. By relying on automated workflows, Entrust empowers operators to secure thousands of critical endpoints with minimal staff resource overhead. Security teams can trust Entrust to run these processes in the background, utilizing certified modules to comply with rigorous corporate policies.
