What JiranSecurity does
JiranSecurity (지란지교시큐리티) is a privately held South Korean cybersecurity software company founded in 2014 and headquartered in Seongnam, Gyeonggi-do, with additional offices in Daejeon and Busan and a regional entity in Japan (지란재팬). The company develops and sells an integrated enterprise security software suite spanning four domains: malware attachment threat response (SaniTOX, MudFix), email security (SpamSniper, MailScreen, JVault+, Cloud MailGate), document security (DocuONE, OfficeHARD), and mobile security (MobileKeeper, MailSafer). Underlying technology includes proprietary CDR (Content Disarm & Reconstruction) for unknown-threat neutralization, AI/ML-based spam and phishing detection backed by a Milvus vector database and a 25-year accumulated signature corpus, and an enterprise mobility management (EMM/MDM) platform.
The company operates a sales-led enterprise GTM combining direct field sales teams organized by mail, document, and mobile business units with a Jiran Group channel-partner network and a dedicated single-tenant cloud (SECaaS) subscription channel for Cloud MailGate. Revenue mechanics are primarily subscription-based across on-premise appliances, cloud-delivered security services, and EMM seat subscriptions. JiranSecurity serves 6,000+ customer organizations across Korean conglomerates, financial institutions, government and defense agencies (Presidential Security Service, Defense Acquisition Program Administration, Korean National Police Agency), e-commerce players (Coupang), and education sector deployments (Dae-gyo). SpamSniper holds the claimed No.1 market position in Korea email security for 25 years, and MobileKeeper is positioned as Korea's leading EMM with 250+ enterprise customers and 1.5M+ users. The company holds 45 commercial technology patents and Common Criteria (CC) EAL2 certifications on SpamSniper and MobileKeeper, which are prerequisites for regulated public-sector and defense procurements. Leadership comprises a dual co-representative director system established in September 2023 with Cho Won-hee alongside Yun Du-sik.
