Why SecuLetter CDR

1
Designed for regulated environments
Implements the content sanitization principles called for in Korean government and regulated-industry content security guidelines — applicable to any organization where execution-based inspection is not permitted.
2
Reconstruct, don't just detect
Rather than searching for files that look risky, MARS disassembles each file, removes malicious elements at the structural level, and safely reconstructs a clean version.
3
Proven at enterprise scale
100% detection rate in independent KISA testing. Support for 309+ file formats. Deployed at 100+ public-sector and financial organizations.
