That’s why Integrity Security Services (ISS) has evolved into OmniTrust.

This transition is more than a rebrand. It reflects how trust must be established, governed, and enforced across modern vehicle ecosystems. For decades, ISS—rooted in Green Hills Software—built its reputation securing the most demanding safety-critical systems in aerospace, defense, and automotive. These are environments where failure isn’t theoretical, it’s operational, financial, and sometimes life-critical.

Today, that same rigor is being applied to a broader challenge: securing the entire trust lifecycle of connected vehicles.

Modern vehicles depend on a complex chain of trust that spans silicon, ECUs, software, cloud services, and now external systems like V2X infrastructure and AI-driven services. But most organizations still face an issue of fragmentation - approaching cybersecurity as a collection of point solutions: secure boot here, OTA updates there, PKI somewhere else.

Trust breaks at the seams, between development and manufacturing, between provisioning and deployment, between updates and long-term lifecycle governance.

OmniTrust addresses this with a unified approach: Trust Lifecycle Management (TLM)—governing trust from design through decommissioning. Our platforms secure billions of devices and software updates annually, with deployments spanning automotive, aerospace, and critical infrastructure.

At AutoTech 2026, OmniTrust will showcase how this lifecycle approach maps directly to the challenges automotive leaders face today:

• Vehicle-to-Cloud Cybersecurity: Establishing provable identity and integrity across ECUs, backend systems, and APIs
• Secure Boot & Code Signing: Ensuring only verified software executes—anchored in hardware root of trust
• Secure OTA Updates: Delivering cryptographically enforced updates with full lineage and rollback protection
• ECU Provisioning & Lifecycle Management: Injecting identity at manufacturing and maintaining it across decades of operation
• V2X / C2X Credential Management: Operating PKI at global scale for vehicles, infrastructure, and mobility ecosystems
• End-to-End Supply Chain Protection: Preventing counterfeit components and securing software pipelines from factory to field
• Fleet Lifecycle Governance: Maintaining continuous visibility, compliance, and control across deployed vehicles

As part of the event, Darryl Parisien, SVP of Solutions Engineering, will join the June 3 panel, “Steering Clear of Cyber Threats: Securing the Modern Vehicle Ecosystem,” to discuss how automotive organizations can move beyond fragmented controls toward enforceable, lifecycle-driven trust.

Because in the era of connected, autonomous, and software-defined vehicles, security is no longer about protecting components. It’s about governing trust across the entire lifecycle.
