Business Details

Broadband Security Inc. is an independent security specialist company that upholds the vision of "creating a convenient and safe network society," and operates three service categories: Security Audit & Consulting Services, Vulnerability Assessment Service, and Information Leakage IT Countermeasure Service. Its customers are primarily large private-sector companies and government agencies. The company holds PCI DSS audit qualification (QSA) as a corporate entity, and its strength lies in its ability to provide an integrated, one-stop service ranging from upstream consulting to 24/7/365 monitoring and operations. Sales are conducted through two channels: direct sales and sales via agents (partners).

Recent Overview

Cumulative nine-month results through Q3 show substantial earnings improvement, with net sales up 8.5% and operating profit up 42.6%

During the cumulative nine-month period of FY2026 (ending March 2026, July 2025 through March 2026), orders progressed steadily due to the success of the comprehensive solution-proposal-based sales strategy, and sales of the Security Audit & Consulting Services grew significantly. Inquiries for the new G-MDR service also increased across industries, expanding the number of companies adopting it. The company achieved net sales of ¥5,111 million (up 8.5% year on year), operating profit of ¥447 million (up 42.6%), and quarterly net profit of ¥300 million (up 66.4%). There has been no change to the full-year forecast (net sales of ¥7,100 million, operating profit of ¥700 million); as of the end of Q3, progress toward the full-year forecast stood at 72.0% for net sales and 63.9% for operating profit. An interim dividend of ¥8.00 has already been paid, and the full-year dividend forecast is ¥16.00 (up ¥1.00 year on year).

Key Products

service
Security Audit & Consulting Services

Provides various security audits and consulting services, including PCI DSS audits (holding QSA qualification). This is the core service category that saw significant sales growth during the cumulative nine months of FY2026 (ending March 2026, quarter data through Q3). It serves as the starting point for the comprehensive solution-proposal-based sales strategy.

service
Vulnerability Assessment Service

A service that professionally diagnoses vulnerabilities in corporate systems, visualizes security risks, and proposes countermeasures. It plays a role in the comprehensive solution proposals offered in conjunction with the audit and consulting services.

service
Information Leakage IT Countermeasure Service

A service that supports the introduction and operation of technical countermeasures against corporate information leakage risk. It also includes product sales such as procuring licenses for overseas security software, and is thus subject to the effects of exchange rate fluctuations.

platform
G-MDR (Full Outsourcing Security Operations Service)

A newly launched, fully outsourced security operations service. Inquiries have been increasing from many companies regardless of industry, and the number of companies deciding to adopt the service increased during the cumulative nine months of FY2026 (ending March 2026, quarter data through Q3). This service contributes to the accumulation of recurring (stock-type) revenue.

Growth Drivers

  • Continued expansion of the information security market driven by the increase in ransomware and the spread of supply chain attacks
  • Expansion of public- and private-sector security investment driven by the government's "Active Cyber Defense" policy and the enforcement of the Economic Security Promotion Act
  • Expansion of deal flow originating from audit and consulting services, and increased G-MDR adoption, driven by the shift to a comprehensive solution-proposal-based sales strategy
  • Underlying demand growth from increased cyber risk associated with the advancement of DX, cloud utilization, and the spread of generative AI
  • Accumulation of recurring (stock-type) revenue and expansion of the customer base through the G-MDR fully outsourced service

Risks

  • Risk of prolonged deal closing due to the transition to comprehensive solution-proposal-based sales (there is a track record of delayed sales recognition occurring in the prior fiscal year)
  • Constraints on service delivery capacity due to difficulty in securing and developing security personnel
  • Risk of contract cancellation by existing customers in recurring (stock-type) services such as managed services
  • Foreign exchange rate fluctuation risk (impact on the cost of procuring licenses for overseas security software: a foreign exchange loss of ¥12,842 thousand was recorded in the cumulative nine months through Q3)
  • Risk of reputational decline, slowdown in new orders, and cancellation by existing customers in the event of a service outage
