Kudelski IoT Labs accredited by Ledger to provide security audit services for Ledger 3rd-party applications

Companies collaborate to accelerate the secure deployment of Blockchain applications 
and Plugins that integrate into the Ledger ecosystem 

Cheseaux-sur-Lausanne, Switzerland, Phoenix, AZ (USA) and Paris, France – August 29th, 2023 – Kudelski IoT, the leading digital security and IoT solutions provider and a division of the Kudelski Group (SIX: KUD.S), has joined forces with Ledger, the world's foremost hardware wallet provider, to offer security audit services for third-party applications within the Ledger ecosystem. With extensive experience in embedded, software and blockchain security, Kudelski IoT Labs will work with Ledger to ensure the safety and security of apps used by Ledger device users for managing their crypto and NFT assets.

The digital wallet market has experienced remarkable growth in recent years, driven by the widespread adoption of cryptocurrencies, digital payments, and the increasing popularity of decentralized finance (DeFi) platforms. As more users turn to digital wallets to manage their digital assets securely, the demand for third-party applications designed to enhance the user experience and offer additional functionality has soared. These applications, ranging from portfolio management tools to DeFi integrations, provide users with a more comprehensive and seamless experience in managing their digital assets. 

As the Ledger ecosystem rapidly expands, a growing number of blockchain-focused,  centralized (cAPPs) and decentralized apps (dAPPs) are seeking integration with the top hardware wallet and its companion app Ledger Live. To maintain Ledger's high-quality standards, all applications must undergo comprehensive functional and security testing. Kudelski IoT Labs is now accredited to conduct these audits for Ledger's ecosystem partners, safeguarding the interests of all parties by addressing potential security vulnerabilities before they escalate. 

"Kudelski Group is renowned as a leading security player in the blockchain space, possessing world-class expertise in both hardware and software security. We're thrilled to collaborate with Kudelski IoT Labs on Ledger application audits and believe this partnership will greatly benefit the Ledger community," said Charles Guillemet, Chief Technology Officer at Ledger.

Hardy Schmidbauer, SVP of Kudelski IoT, added, "We're honored to be accredited by Ledger as a security audit partner. Ledger products are a crucial part of the infrastructure layer that will drive the next wave of DeFi and other blockchain applications. We're confident that our expertise in threat and risk analysis, security assessment, and blockchain will enable us to play an increasingly significant role in serving Ledger ecosystem partners."
