From threat detection to risk management and prevention, ThreatSonar Plus empowers enterprises to navigate the AI era Facing increasingly stealthy attacks driven by AI agents, traditional cybersecurity defenses are no longer sufficient. TeamT5, a leading threat intelligence provider in the Asia-Pacific region, today unveiled a new solution at CYBERSEC 2026 in Taiwan: ThreatSonar Plus , a ThreatSonar Plus Extensive Endpoint Assessment Platform built for AI environments. In addition to showcasing its advanced automated defense capabilities, TeamT5 also introduced its new brand identity, marking both a commitment to deep technological innovation and a milestone in its global expansion in AI cybersecurity. ThreatSonar Plus Eliminates Blind Spots in AI Agent Defense As enterprises accelerate the adoption of AI agents to drive automation, new forms of cybersecurity risk are emerging. Sung-ting Tsai, CEO of TeamT5, noted that improperly configured AI agents may lead to sensitive data leakage or exposure to malicious code injection. Given that AI agents often integrate with external services, insufficient access control can easily result in unauthorized access to confidential data. These threats are highly automated and difficult to detect, rendering traditional cybersecurity solutions ineffective. Enterprises must urgently reassess and establish protection mechanisms specifically designed for AI deployments. The newly launched ThreatSonar Plus platform directly addresses these defense gaps in AI environments. Built around three core pillars—asset inventory, risk detection, and AI agent identification—the platform enables enterprises to gain precise visibility into critical assets and AI deployments. Through in-depth analysis, administrators can quickly identify high-risk vulnerabilities and prioritize remediation strategies accordingly. Key features of ThreatSonar Plus include: AI agent risk identification, including sensitive data exposure, malicious commands, and autonomous agent behaviors Support for SEMI E187 to meet industry security and compliance requirements Rapid identification of high-risk vulnerabilities with severity-based prioritization for faster response System configuration assessment aligned with CIS benchmarks, with actionable hardening recommendations New ThreatVision Cybercrime Intelligence Reports Focus on Dark Web Cybercrime In addition to endpoint security, TeamT5 has recently introduced ThreatVision Cybercrime Intelligence. Built on TeamT5’s 20+ years of APAC threat research, it covers the Deep & Dark Web, underground forums, Telegram, and cybercrime communities, delivering expert-validated intelligence insights that analyze cybercrime operations, ransomware activity, data trades, and dark web developments from attacker’s perspective. ThreatVision Cybercrime Intelligence helps enterprises identify emerging cybercrime risks earlier, understand attacker tactics and targets, and prioritize defensive actions. By gaining visibility into cybercriminal activity across the Deep & Dark Web, enterprises can more accurately assess risk and shift from reactive response to proactive defense. From Asia-Pacific to Global Markets: Brand Transformation Signals Strategic Vision Another highlight was the debut of TeamT5’s new brand identity. Built on the concept of “focus insights and sharpened vision,” the redesign reflects its precision in threat detection and ability to help clients make decisive security decisions. CEO Sung-Ting Tsai said the rebrand marks TeamT5’s evolution into a more mature and trusted cybersecurity company, while reinforcing its global expansion strategy. Founded in Taiwan, TeamT5 has established a strong foothold in Japan and South Korea, and in recent years has expanded into Southeast Asia, including Thailand, Vietnam, Malaysia, and Singapore, with further extension into European markets. As its global footprint grows, the company continues to strengthen local partnerships and service capabilities to enhance competitiveness. TeamT5 has also initiated plans for a public offering, progressing according to schedule to support future capital market entry and long-term brand sustainability.
