Hardware-Level Cybersecurity for Today’s Connected Devices
Epteck integrates Secure Boot, TrustZone, encrypted firmware, and secure OTA pipelines directly into your embedded architecture—helping you prevent tampering, pass compliance audits, and build devices that are secure from day one.
Trusted by Industry Leaders
Cyber Resilience Starts at the Hardware Level
Today’s embedded and IoT products face more risk than ever—from firmware tampering and IP theft to regulatory failure and security breaches. Hardware-level protection is no longer just a feature—it’s a requirement. Epteck helps you implement cybersecurity at the core of your product, not as an afterthought, so you can build safer, certifiable, and future-proof systems.
Protect Your Product
Secure Boot and firmware encryption prevent unauthorized access, cloning, and malware injection.
Comply with Regulations
We help align your system with CRA, CE, GPSR, IEC 62443, and secure firmware lifecycle practices.
Secure OTA & Lifecycle
Ensure firmware updates are authenticated, encrypted, and rollback-safe—with traceability and audit readiness.
Build Trust with Your Users
Demonstrate integrity & security by design—essential for B2B hardware, consumer devices & industrial deployments.
Future-Proof Against Threats
Reduce long-term risk by integrating cryptographic identity, hardware root-of-trust, & secure update paths into your device.
Our Embedded Cybersecurity Services
At Epteck, we deliver embedded-first cybersecurity that’s engineered into your firmware, hardware, and device update processes. Whether you’re securing your bootloader, preparing for CE or CRA compliance, or hardening your OTA lifecycle, our team builds systems that are reliable, scalable, and secure by design.
We design and implement secure boot chains to validate firmware authenticity from power-up—enforcing a trusted execution path.
- U-Boot or MCU-based secure boot customization
- Chain-of-trust setup: ROM → Bootloader → Kernel → App
- Secure key storage, cryptographic signature validation
- Platform support: STM32, NXP i.MX, TI, Nordic, and more
We help you design firmware and system architecture with built-in resilience, privilege separation, and secure communication pathways.
- Embedded threat modeling (firmware ↔ hardware interfaces)
- Memory protection, privilege ring separation, HAL hardening
- Secure-by-design OTA update workflows
- Runtime attack surface minimization (stack checks, watchdog, etc.)
We integrate platform-level trust anchors such as hardware-based crypto, TrustZone, and secure key provisioning.
- ARM TrustZone Secure/Non-Secure world split
- Key storage and crypto coprocessor integration (AES, ECC, SHA)
- Tamper detection, secure debug lockout
- TPM/SE support for embedded Linux platforms
We prepare your device for CE, GPSR, and EU Cyber Resilience Act compliance by testing critical security functionality and documentation.
- Secure code reviews (C, C++, Python, shell scripts)
- Boot and OTA failure injection tests
- CRA gap analysis & secure development documentation
- Pre-certification audit support for notified bodies
We build update systems that preserve integrity, avoid rollback attacks, and prevent firmware hijacking.
- Encrypted OTA pipeline setup (via MQTT, HTTPS, BLE)
- Version pinning, rollback prevention, key rotation
- Dual-bank firmware strategies (A/B partition)
- Secure cloud-to-device messaging infrastructure
Cybersecurity That Delivers—In Real Products
From secure energy gateways to BLE-enabled health devices, Epteck has delivered embedded cybersecurity solutions that pass compliance, resist attacks, and scale with confidence. Explore how we’ve helped clients implement secure boot, OTA protection, and hardware-level resilience in the real world.
Secure Linux BSP for Energy Systems
Challenge: Energy gateway firmware needed secure boot and CE/GPSR compliance without redesigning the platform.
Solution: Epteck implemented secure boot with encrypted firmware validation, OTA update integrity checks, and audit logs for compliance documentation.
Result: Device passed CE and EMC on first attempt, OTA bugs reduced by 80%, and platform secured against unauthorized flashing.
SIMOT (Industrial / Energy Telemetry)
Challenge: Industrial telemetry gateways faced increasing pressure to ensure update integrity and prevent device cloning.
Solution: Epteck integrated bootloader-level firmware validation and deployed TrustZone separation for OTA download & apply processes.
Result: Rolled out to 50+ installations with >99.9% OTA update success and no observed tampering or rollback incidents.
