What Information Security does

Information Security Inc. (iSEC) is a privately held Japanese cybersecurity company founded in September 2014 by Yoshihisa Suzuki and headquartered in Kobe, Hyogo Prefecture. The firm specializes in OT/ICS security for critical infrastructure operators (electricity, gas, water) and global manufacturers with factory networks, a relatively underserved niche within Japan's broader IT security market. iSEC is one of the few Japanese vendors with explicit IEC 62443-2-1 compliance expertise and METI Information Security Service Standards certification, positioning it for regulated procurement in critical infrastructure and large manufacturing accounts.

The company's technology stack combines distributed third-party products (GREYCORTEX MENDEL for AI-based network traffic analysis and Nozomi Networks Guardian for OT asset visibility and anomaly detection) with the proprietary i-Auditor platform, an agentless file-server access monitoring system. Services are delivered through the i-Cybertech brand and span risk assessment, network assessment, factory network delay investigation, 24/7 SOC monitoring with optional on-site response, and cybersecurity training for control system operators and engineers. The architecture emphasizes passive, non-disruptive monitoring suitable for production environments, with integration into Palo Alto firewalls, Cisco ISE/ASA, Splunk, and Logstorage.

iSEC generates revenue through four streams: subscription-based SOC services (24/7 monitoring from ¥190,000/month for operations), professional services for risk and network assessment, product resale (perpetual licenses and subscriptions for distributed products plus proprietary i-Auditor annual licensing), and corporate cyber training programs. Pricing is predominantly quote-based, with multi-year contract structures typical for SOC and product deployments. Go-to-market is direct enterprise sales in Japan targeting industrial verticals, with a recently initiated channel partner recruitment program to supplement direct coverage. The company employs 51-100 people with an average age of 29, has been consistently cash-generating with no disclosed external funding rounds, and maintains a global English-language website signaling intent to support overseas factory sites of Japanese-headquartered manufacturers.

Direct peers

• LAC Co., Ltd. Tokyo-based Japanese cybersecurity services company offering SOC, security assessment, and incident response — a domestic specialist competitor targeting many of the same enterprise customers iSEC serves, although with broader rather than OT-only focus.
• Claroty: Global OT/ICS cybersecurity platform with asset discovery, vulnerability management, and threat detection capabilities directly comparable to Nozomi Networks Guardian (which iSEC distributes). Both target critical infrastructure and manufacturing customers with passive network monitoring suitable for production environments.
• Dragos: OT cybersecurity specialist focused on industrial control systems, offering threat detection, asset visibility, and incident response — the same problem set iSEC solves for Japanese critical infrastructure and manufacturing operators, including IEC 62443-aligned work.
• Nozomi Networks: iSEC's primary OT product partner and a global leader in OT/IoT security and visibility for ICS environments in manufacturing, electric, gas, water, chemical, and petroleum — directly competing with iSEC's bundled SOC + Guardian service in Japan and APAC while also serving as iSEC's key distribution relationship.
• S&J Corporation: Japanese cybersecurity consulting and services firm focused on offensive security and SOC — competes with iSEC for Japanese enterprise and critical infrastructure security work and operates at broadly similar organizational scale.

Broad incumbents

• NRI Secure Technologies: Major Japanese cybersecurity services firm (subsidiary of Nomura Research Institute) providing managed security, assessment, and consulting to enterprise customers in Japan. Overlaps with iSEC's SOC and security assessment offerings for large industrial customers from a much larger delivery base.
• Tenable (Industrial Security / formerly Indegy): Major vulnerability management platform that acquired Indegy to add OT/ICS security capabilities, including asset discovery and threat detection similar to Nozomi Guardian. Reaches Japanese enterprise customers via broader IT security offerings beyond iSEC's OT specialty.
• NTT Communications / NTT Security: Subsidiary of NTT Group offering managed security services, SOC monitoring, and security consulting across Japan. Competes directly with iSEC's SOC services for critical infrastructure customers, while leveraging broader telecom and IT services scale that iSEC cannot match.
• Trend Micro Japan: Large Japanese-headquartered cybersecurity vendor with broader product portfolio but increasingly offering OT/industrial cybersecurity services. Overlaps with iSEC's enterprise customer base and ICS-targeted security services from a much larger platform.
• Macnica Networks: Japanese IT distribution and managed services firm with a security services arm offering MSSP and SOC capabilities. Competes with iSEC's channel-recruitment ambitions and resold security product portfolio across the Japanese enterprise market.
