SecuLetter

SecuLetter develops security software that scans and blocks malicious content hidden inside digital files, such as documents and attachments, before they can harm an organisation's systems.

Its products cover email security, file transfer security, web-service file security, and cloud security, and are supplied to corporate and institutional customers. Listed on KOSDAQ, Korea's tech-focused small-cap exchange, the company's entire product portfolio is built on a proprietary platform it calls MARS, which uses automated reverse-engineering, the process of dismantling and analysing code to find hidden threats, as its core detection method.
