CHT Security is the subsidiary of Chunghwa Telecom, Taiwan’s largest telecommunications and internet service provider. It is a leading managed security service provider (MSSP) in this region with expertise in delivering telco-centric and comprehensive cybersecurity solutions, covering the entire spectrum of cyberattacks—before, during, and after an incident.

The company’s portfolio includes network security services designed to thwart cyber threats at the network backbone. Beyond professional cybersecurity services, it develops products like SecuTex Network Protection, a system for network packet sniffing and network anomaly and threat detection, SecuTex Endpoint Detection, a software for endpoint rapid test and security management, and CypherCom, an end-to-end encryption communications system, providing security at the hardware level.

As an A-grade cybersecurity service and solutions provider, CHT Security extends its comprehensive solutions to over 350,000 households, 20,000 SMEs, and 200 large enterprises and government institutions. The company specializes in both defensive and offensive services, including cybersecurity assessment, SOC monitoring, IoT (Internet of Things) & OT (Operational Technology) security services, incident response services, and digital forensics of cyber incidents.

“Our state-of-the-art cyber security solutions emerge as a trusted partner for financial institutions, enterprises, and government departments in fortifying cyber defense against even the most sophisticated attacks,” says Lin Fong-Jheng, manager, CHT Security.

A holistic approach to offensive security sets the company apart. CHT Security goes beyond traditional penetration testing to a wide range of offensive security measures, including penetration testing, vulnerability assessments, mobile app and IoT security testing, social engineering simulations, and red team exercises to strengthen security against sophisticated attacks.

Unlike its competitors, the company’s ISO 20000-certified red teaming service, top-notch grades from government evaluations, and a history of eight years of excellence in penetration testing position it as a formidable force in navigating the digital realm with expertise and precision. Backed by a team with decades of practical offensive and defensive experience, along with a wide range of front-line certifications like CREST Registered Tester (CRT), OSCE³, OSCP, OSWE, OSEP, OSED, GPEN, GWAPT, CISSP, CSSLP, and LPT is a testament in maintaining a proactive stance against the ever-evolving landscape of cyber threats.

For instance, the rise of the pandemic has brought a shift toward remote work, bringing forth a new set of challenges, particularly in VPN security. CHT Security’s red team identified many companies needing more robust identity validation for remote employees accessing networks via VPNs. Leveraging leaked database credentials with matching passwords, the red team successfully infiltrated internal networks posing as regular employees, helping companies identify vulnerabilities.

“Our seasoned red team handling over a thousand systems annually has discovered approximately 5,800 vulnerabilities in 1,500 systems across 270 organizations, showcasing our decades of accumulated expertise,” says Victoria Wu, marketing manager, CHT Security. “To stay in cyber warfare front line, we have designed a suite of self-developed tools like information-gathering tools, deserialization exploit tools, CAPTCHA cracking and reporting aid tools, app protection cracking, and a self-built attack and defense training platform.”

The company’s consistent and unmatched performance is reflected in the numerous awards and acknowledgments it has received over the years, including the 2023 Taiwan Cybersecurity Services Company of the Year Award by Frost & Sullivan, 2023 & 2022 COMPUTEX Best Choice Award, and top ratings across various categories in the annual review by Taiwan’s Security Department of the Executive Yuan. These accolades are not merely governmental recognition. It is a testament to its prowess in SOC monitoring, cybersecurity evaluation, vulnerability assessment, penetration testing, and social engineering.

Its proven record of uncovering over 100 CVEs, with a remarkable 70 percent classified as high or critical risk, solidifies the company’s commitment to staying at the forefront of cybersecurity expertise. CHT Security is on a journey to stay abreast of black hat hackers and hone its capabilities in addressing cybersecurity concerns at every stage of the attack lifecycle. It continues to lead in innovation, establishing new benchmarks for excellence in cybersecurity.
