DDS

What DDS does

DDS (Digital Data Solution Inc.) is a Tokyo-based, privately held Japanese data security company that operates three integrated business lines: data recovery (DDR/DDB/DDW/DDP), digital forensics (DDF/DDE/DDL/DDC), and cybersecurity (D-SOC/DDHBOX/DDH). Founded in 1999 and rebuilt by current sole owner Masashi Kumagai following a 2014 predecessor bankruptcy, the company holds 17 consecutive years as Japan's No.1 data recovery provider by domestic sales and reports cumulative 500,000+ consultations since 2011. Its technology stack centres on a Class 100 clean room lab, one of the world's largest donor parts warehouses, and IBM QRadar SIEM powering the newly opened D-SOC in Roppongi, with proprietary capabilities in HDD scratch recovery, smartphone data extraction, dark-web monitoring, and AI-based hardware fault prediction. The company's operating model combines direct enterprise sales, inside sales, regional bank channel partnerships (Hokkoku, Tomami, Hokkaido, Chugoku, Hyakugo, Miyazaki), and consumer channels such as Yamada Denki, supplemented by a May 2024 capital and business alliance with Ricoh Japan targeting ¥10 billion cumulative revenue over three years. Revenue is generated through both subscription/recurring services (DDW recovery guarantee, D-SOC, Digital Data Advisory) and project-based professional services (forensics investigations, incident response, government agency support). Customer base spans Japanese government and police agencies, regional banks, listed enterprises, SMBs, and individual consumers, with international expansion now underway via a Vietnam franchise launched November 2025.

Core offering

DDS operates an integrated data security business covering three pillars: data recovery (recovering lost data from failed HDDs, smartphones, RAID and servers), digital forensics (investigating deleted or hidden digital evidence for criminal and corporate cases), and cybersecurity (24/7 SOC monitoring, endpoint security, vulnerability assessments, penetration testing, dark web monitoring, and hacking countermeasures). The company serves Japanese enterprises, government agencies, financial institutions, and individual consumers through direct sales, inside sales, regional bank channels, and a Ho Chi Minh City franchise operation.

Product overview

DDS offers a comprehensive data security platform organized around three core business units: Data Recovery (DDR), Digital Forensics (DDF), and Cybersecurity. The main products include DDR (digital data recovery service with 17 consecutive years of No.1 domestic sales), DDB (automated backup), DDW (subscription-based recovery guarantee), DDP (AI-powered fault prediction), DDF (digital forensic investigation), DDE (internal fraud monitoring), DDC (secure data erasure), DDH (government-grade hacking countermeasures), DDHBOX (endpoint security product with 7,000+ deployments), and D-SOC (24/7 SIEM/SOC monitoring service). These products work together as an integrated suite covering the full data lifecycle: prevention through backup and security products, incident response through forensics and monitoring, and recovery through the core DDR service.

Recent moves10 records

Expansion highlights6 records

Broad incumbents

• Trend Micro: Global Japanese-headquartered cybersecurity vendor with significant Japan presence offering endpoint, network, cloud security, and managed detection/XDR services. Wider portfolio than DDS' integrated three-pillar focus, but directly competes in Japanese SOC and incident response.
• Mandiant (Google Cloud): Global incident response, threat intelligence, and managed defense leader (now part of Google Cloud). Sets the upper bar for high-end digital forensics that DDS' DDF practice competes against.
• Bell Info Systems / NSCO: Japanese managed security services provider focused on SOC operations, security monitoring, and incident response. Competes with D-SOC for mid-to-large enterprise customers in Japan.
• NRI SecureTechnologies: Major Japanese managed security services provider under Nomura Research Institute, offering SOC, vulnerability assessment, penetration testing, and consulting. A more established alternative for DDS' enterprise and financial-services customers.
• NTT Data Group: Japanese IT services giant providing SOC, managed security, and incident response as part of its broader systems integration portfolio. Competes with DDS for large government and enterprise contracts.

Direct peers

• AOS Data (AOS Leasing): Japanese data recovery, data backup, and data erasure services provider. Most directly comparable peer in DDS' legacy DDR business within the Japan market.
• CyCraft Technology: Taiwan-headquartered cybersecurity vendor focused on digital forensics, threat hunting, and AI-driven incident response. DDS' existing CyCraft Japan partnership also positions it as a partial overlap on dark web monitoring and forensics.
• LAC Co., Ltd. Japanese cybersecurity firm offering SOC services, incident response, digital forensics, and security consulting. Direct competitor across DDS' D-SOC, DDF, and vulnerability assessment lines for Japanese enterprise and government customers.
• S&J Corporation (Japan Cybersecurity): Japan-based cybersecurity and digital forensics provider offering incident response, forensic investigation, and security consulting. Closely comparable in scope to DDS' DDF business.

Emerging players

• SecureWorks (Dell Technologies): Global MSSP offering managed detection, incident response, and vulnerability management. Competes with DDS' D-SOC for multinational and Japanese clients needing managed security at scale.
