About CyStack·Hanoi · 2017
Helping businesses stay resilient against cyber threats
Founded in Hanoi in 2017, CyStack builds cybersecurity products and services for organizations across Vietnam and the region, covering penetration testing, 24/7 monitoring, and sensitive data protection.
Our story
In 2017, Vietnam was riding an unprecedented wave of digital transformation. New technology companies launched every quarter to reinvent legacy industries, and they became fresh targets for attackers, facing rising technical and financial hurdles to defend themselves.
Trung Nguyen, by then a recognized application security researcher honored in the Hall of Fame of many leading global technology companies, saw the need for a security company that spoke the language of Vietnamese businesses. He founded CyStack to deliver a full stack of cybersecurity offerings (Cyber and Stack), broad enough for individuals and deep enough for the enterprise.
From a small research team, CyStack now serves more than 600 customers in multiple countries. We operate proprietary products such as WhiteHub, Locker, and CyStack Endpoint, while our experts continue to disclose new security vulnerabilities and present at international security conferences.
Our mission
We build a safer internet by combining seasoned security practitioners, proprietary technology, and a strong community of independent researchers.
How we approach cybersecurity
Every CyStack product and service solves a specific problem in the security lifecycle, from product development to long term operations.
Operations security
Round the clock infrastructure monitoring, vulnerability management, and incident response keep enterprise systems protected throughout their lifetime.
Data security
Locker secures enterprise credentials, CyStack Endpoint manages devices, and Data Leak Detection stops sensitive information from leaving the perimeter.
Security community
CyStack researchers publish CVEs and speak at Black Hat, T2FI, and XCON, while the WhiteHub community connects thousands of researchers across the region.
