Notable Client Engagements: The company has worked with prominent organizations including Native Labs (smart contract audits), Linux Foundation Public Health (COVID-19 contact tracing application audits), 1Password (extensive pentest in collaboration with Cure53), Mozilla Thunderbird (Enigmail vulnerability detection), and many others in the blockchain and cryptocurrency space.

Key Strengths
