Crypto wallet company Ledger has appointed Charles Guillemet as the company’s new Chief Technology Officer (CTO).

Founded in 2014, Ledger develops security and infrastructure solutions for cryptocurrencies as well as blockchain applications for individuals and companies, by leveraging a distinctive, proprietary technology. The company’s products include the Ledger hardware wallet line, which has already sold in nearly 170 countries.

Guillemet, who joined Ledger in 2017 as Chief Security Officer, founded the company’s security department and security evaluation lab, The Ledger Donjon. During his time at Ledger, Guillemet has overseen security assessments for Ledger’s products, procured independent security certifications for both the Ledger Nano S and Ledger Nano X, and has built industry leading open source hardware and software security tools. Guillemet’s Donjon team has also assessed the security of competitor devices, and responsibly disclosed vulnerabilities to contribute to raising the bar for security throughout the blockchain ecosystem.

“Charles has played a pivotal role in building Ledger into the security company it is today,” said Pascal Gauthier, CEO of Ledger. “We are proud to have the industry’s top security mind on our team and are confident that his appointment to CTO will further enhance Ledger’s security technology in an increasingly connected world where hackers are becoming more sophisticated.”

As Ledger’s new CTO, Guillemet’s task is to bring further integration to Ledger’s security and technology teams.

“Throughout my time at Ledger I have had the pleasure of leading a world class team of security researchers that has set the standard for blockchain security,” said Guillemet. “Security and technology go hand and hand at Ledger, so my appointment to CTO is a natural extension of the critical work we are doing everyday to improve the security of the products we build.”
