Let’s be honest, the average IoT device today knows more about you than your coworkers do — and probably listens better, too. But if that device isn’t properly secured, it could leave your sensitive data vulnerable. Enter Silicon Labs Secure Vault — the digital security system your smart devices deserve (and really need).

What Is Secure Vault IoT Security Framework?

Secure Vault is Silicon Labs’ built-in security framework for our wireless chips and MCUs. It’s a collection of hardware and software features designed to keep your connected devices safe from tampering, snooping, and other forms of digital troublemaking. Certified to PSA Level 3, Secure Vault provides locked-down protection at the silicon level so security isn’t just an afterthought.

Key Features of Secure Vault Technology (A.K.A. Why Hackers Will Hate You)

• Secure Boot with Root of Trust
  Secure Boot is the firmware version of “no ID, no entry.” Your code must be signed and verified before the device allows it to run. If something looks fishy, it shuts down before it even starts.
• Secure Debug
  Secure Debug is helpful when developing, but it’s also one of the easiest ways to poke around inside a device. Secure Vault lets you lock that door — and only unlock it under very specific (and secure) conditions.
• Tamper Detection
  If someone physically tampers with the chip, Secure Vault’s Anti-Tamper feature notices and reacts. It can wipe sensitive data, shut down access, or basically throw up its hands and say, “Not today!”
• Hardware-Accelerated Crypto
  Need secure communication, encrypted storage, or random number generation? Secure Vault handles all of that with built-in hardware support. It’s fast and efficient for doing your math.
• Secure Key Storage and Management
  Secure Vault’s Secure Key Management stores your cryptographic keys in a locked-down, isolated area of the chip. The keys are stored, wrapped in a flash, and never leave the vault unprotected. Think of it as a digital safe that doesn’t lose the combination.
• Unique Device Identity and Attestation
  Each chip comes with a unique, unforgeable identity. With Secure Attestation you can trust it’s your device and not a clever fake trying to sneak onto your network.

Who Is IoT Device Security For?

If you’re building any kind of connected IoT device — whether it’s in a smart home, factory, hospital, or just something people carry in their pockets — Secure Vault is for you. It’s especially useful in:

• Home automation and consumer electronics
• Industrial IoT and remote monitoring
• Smart meters and infrastructure
• Medical devices and wearables

Basically, if the device handles data, controls anything important, or connects to the internet, it needs real security. And Secure Vault delivers that in a way that’s efficient, scalable, and standards-compliant.

Build Trustworthy IoT Devices with Secure Vault

In a world full of connected gadgets, it’s not enough to just work — IoT devices also need to be trustworthy. Secure Vault makes that possible by protecting your data, your firmware, and your device’s identity right at the hardware level. It’s proactive protection, not reactive damage control.

So if you’re developing an IoT device, don’t wait until the last minute to bolt on security. With Secure Vault, you get it baked right into the chip — and that’s a much smarter way to build trust in the connected future.
