Go Beyond Embedded Software: Expert-Level Silabs Security

Hardware-level security is now a baseline requirement for market entry, not just a differentiator. It’s the foundation of your brand’s reputation and IP. But implementing hardware-level security is complex. Standard development partners are often not equipped to handle the advanced capabilities of the Silabs platform. We specialize in these complex implementations.

As a dedicated Silicon Labs Design Partner, we have deep expertise in their most advanced security and provisioning technologies. We don’t just “use” security; we architect your product around it from day one, ensuring you get the full benefit of the silicon you’re paying for.

Silabs Secure Vault Implementation Services

Silicon Labs’ Secure Vault is the industry leader in IoT security, but it requires expert implementation to be effective. Our IoT security design services leverage its full power:

PSA Certified Level 3 Implementation

Silabs hardware protects against both scalable software attacks and physical hardware attacks. Our teams are experts in building products that correctly utilize this pre-vetted technology, helping you achieve your own end-product certifications. This is required for upcoming regulatory standards (like EU Cyber Resilience Act or US Trust Mark).

Secure Boot Implementation

We use the hardware root of trust to implement a true secure boot process, ensuring your device only runs authenticated, untampered embedded software.

Secure Identity & Attestation

We provision your devices with unforgeable secure identities, allowing them to prove who they are to your cloud and preventing counterfeit devices from joining your network.

Anti-Tamper & Secure Debug

We implement advanced physical security, using Secure Vault’s features to lock down debug ports and protect against side-channel attacks in the field.

IoT Supply Chain Security with Silabs CPMS

Your intellectual property is your most valuable asset. How do you protect your embedded software when you send it to an untrusted contract manufacturer?

We provide IoT supply chain security services utilizing Silabs’ Custom Part Manufacturing Service (CPMS).

  • Secure Factory Provisioning: With CPMS, you no longer send your IP to the manufacturing floor. Custom part numbers are created and deliver your secure firmware, keys, and certificates directly to Silabs.
  • Pre-Provisioned, Custom Parts: Your contract manufacturer receives a chip that is already pre-programmed with your secure bootloader and unique device identity. It’s a “black box” to them, and your IP is never exposed. Eliminate the risk of ‘ghost shifting’ or IP theft at the contract manufacturer level by removing the keys from the factory floor entirely.
  • Optimize Manufacturing & Costs: This process simplifies your production line, reduces flashing time, eliminates the need for complex key-injection infrastructure, and lowers manufacturing costs.

Flexible Development: Onshore, Hybrid, or Long-Term Offshore

We tailor our team to your specific needs. Whether you need a security architecture review by our US experts or a dedicated team to implement CPMS across a product line, we have a proven delivery model that fits.

Hardware-Based IoT Security FAQs

What is Silabs CPMS and why is it important?

CPMS (Custom Part Manufacturing Service) is a Silabs service that lets you order factory-programmed chips. It is a cornerstone of IoT supply chain security. We use it to pre-load your embedded software and keys directly at the Silabs factory, meaning your contract manufacturer never sees your IP.

What are secure boot implementation services?

This is our service to implement a secure boot process on your device. We use the hardware root of trust in Secure Vault to ensure that, every time your device powers on, it cryptographically verifies that the embedded software it’s about to run is authentic, signed, and untampered with.

Why is PSA Certified Level 3 design a major differentiator?

Most IoT security is only certified to protect against software attacks. A PSA Certified Level 3 design proves the chip can also withstand physical hardware attacks. By using our IoT security design services, you are building your product on a proven, third-party-validated foundation.

How does your Silabs ODC help with security?

Security requires specialized knowledge of the silicon. Because our ODC team works exclusively with Silabs parts every day, they have deep familiarity with the security peripherals, registers, and tools (like Simplicity Studio’s security settings) that a generalist engineer might miss. We leverage this “Center of Excellence” to build a team for you that gets security right the first time.
