What NTT Security Holdings. does
NTT Security Holdings Corporation is the cybersecurity-specialized subsidiary of NTT Group (Nippon Telegraph and Telephone), operating primarily through its Japanese operating entity NTT Security Japan, established in March 2013. The company delivers a full-lifecycle managed security services portfolio spanning prediction, diagnosis, protection, detection, response, and recovery, with core offerings including the Aurora endpoint security family (Aurora Protect, Aurora Endpoint Defense, and the newly launched Aurora Managed Endpoint Defense / AMED in partnership with Arctic Wolf), a proprietary SIEM-based MDR service with 24/7 SOC monitoring across IT, OT, and cloud environments, and the SOC in Pocket hardware-appliance service for small and mid-sized businesses. The technology stack combines the company's own SIEM platform and threat analysis engine with third-party AI capabilities, most notably Arctic Wolf's Alpha AI predictive endpoint protection and CyCraft's AI-driven forensic analysis, alongside OT security products from TXOne Networks and threat intelligence from Blackwired's ThirdWatch platform.
The company generates revenue through subscription-based managed security services, project-based professional services (consulting, assessments, incident response), and security hardware/software resale, with quote-based enterprise pricing and a publicly disclosed entry-level price of approximately 100,000 JPY per month for the SOC in Pocket service. Go-to-market is anchored by direct enterprise sales leveraging NTT Group's existing customer relationships, supplemented by channel partners including NTT Bizlink, NTT Business Solutions, and Nikkei Tsugo System for the SMB segment, and NTT DOCOMO Business as a secondary agent for KnowBe4 distribution. The customer base spans large Japanese enterprises and conglomerates, manufacturing verticals (automotive, chemical, industrial) with deep OT security needs, government and critical infrastructure operators, and the SMB segment served through SOC in Pocket, with case studies including NTT Urban Development and JNC Petrochemical. The group also maintains European operations through wholly-owned subsidiaries in Sweden and Norway, and a Cyber Active Defense Research Institute for threat intelligence development.
