Engineering Secure Multi-ECU
OTA Lifecycle Systems
Enabling Continuous Software Evolution Across Global Fleets
Software-defined vehicles demand continuous evolution, yet many OEMs face fragmented update architectures, limited fleet visibility, increasing cybersecurity mandates under UN R155 and R156, and the risk of costly field failures or recalls. Managing multi-ECU software OTA updates, regional variant complexity, and post-sale feature activation requires a structured, production-ready OTA foundation.
At SRM Technologies, we engineer secure, scalable OTA solutions and lifecycle ecosystems, integrating vehicle software, backend platforms supporting over-the-air diagnostics and updates, and enterprise systems into a unified operating model. Our teams bring deep embedded, cloud, and cybersecurity expertise to ensure reliable deployment, regulatory alignment, and full software traceability across global fleets.
Partner with us to build resilient, compliant, and future-ready OTA ecosystems that keep your vehicles evolving long after launch.

Our Areas of Expertise
FOTA & SOTA Engineering
Enable continuous vehicle evolution for your customers through our end-to-end firmware and software OTA engineering across powertrain, chassis, ADAS, and infotainment domains. Our team designs adaptive delta compression algorithms that minimize bandwidth consumption without compromising update integrity.
We implement robust A/B update architectures to ensure vehicles remain operational during every update cycle, eliminating downtime risk. From secure package generation and cryptographic signing to in-vehicle client execution and post-update validation, we deliver production-scale FOTA and SOTA pipelines built for heterogeneous ECU environments.
Campaign & Rollout Management
Deliver controlled, multi-stage OTA rollouts through intelligent campaign orchestration and configuration governance. Our expertise enables precise, multi-stage, phased deployments, vehicle-attribute-based targeting, and regional policy configuration across complex variant landscapes.
Our team builds version and configuration management logic to handle model year differences, regulatory requirements, and trim-level complexity. From pilot validation to full-fleet deployment, we deliver scalable rollout systems that balance speed, safety, and compliance across global vehicle programs.
OTA Security & Regulatory Compliance
Protect your connected fleet and customer trust with our zero-trust automotive OTA security architectures aligned with the most stringent global regulatory requirements, including UN R155, UN R156, and ISO 21434. Our cybersecurity expertise embeds multi-party code signing, encrypted payload distribution, and hardware root-of-trust verification across the entire update chain.
We support OEM programs with CSMS documentation, structured risk assessments, and type-approval evidence preparation. Our team ensures every OTA pipeline remains traceable, tamper-proof, and audit-ready throughout the vehicle’s connected lifecycle.
SDV Lifecycle Management
Maintain full software visibility and governance across every vehicle in your fleet through our structured SDV lifecycle architectures. Our integrated capability brings together digital software twins, real-time fleet-wide inventory systems, and factory OTA with end-of-line flashing frameworks to seamlessly align manufacturing configuration with post-sale evolution.
We design feature lifecycle systems that support feature-on-demand activation, entitlement tracking, and ECU-level version governance — ensuring complete visibility into what software is running on every ECU, in every vehicle, at any stage of the lifecycle.
Cloud & Backend Integration
Scale your OTA operations seamlessly across global fleets through our cloud-agnostic backend integration expertise. Our team leverages microservices-based architectures that ensure modular deployment, independent scaling, and fault isolation across campaign management, package distribution, and telemetry ingestion.
We establish secure bidirectional vehicle-to-cloud pipelines enabling real-time update tracking, remote command execution, and continuous fleet monitoring. Our integration capability connects OTA platforms with enterprise databases, identity systems and dealer networks, bringing your OTA operations together into a single, coordinated ecosystem that limits post-sale agility.
Remote Diagnostics & Monitoring
Reduce field failures and improve post-sale customer experience through our remote diagnostics and monitoring capabilities built on secure OTA infrastructure. We implement real-time fault detection pipelines, diagnostic trouble code aggregation, and remote ECU health monitoring to identify issues before escalation to recalls.
Our team ensures every update and remote interaction is captured through structured audit trail management, maintaining traceability across the vehicle lifecycle. We also enable features-on-demand activation and remote ADAS recalibration via OTA, reducing workshop dependency while enhancing the customer ownership experience.
