Introducing BRIDGED PURPLE SOC: The Next-Gen Attack-Defense Integrated SOC Service

Introduction to BRIDGED PURPLE SOC

On May 20, 2023, BRIDGED, a Tokyo-based company, announced the launch of its next-generation security operations center (SOC) service, the BRIDGED PURPLE SOC. This offering combines the expertise of 24/7 SOC analysts with advanced AI technologies to create a hybrid, AI-driven SOC for ongoing security and defense enhancement. BRIDGED aims to close the gap between attack and defense by integrating offensive and defensive perspectives.

Partnership with Leading Cybersecurity Firms

The BRIDGED PURPLE SOC service stands out through its collaboration with two renowned companies: NSHC Inc., a South Korean organization specializing in offensive cybersecurity research with over 20 years of experience, and LogSpect, a Tokyo-based firm recognized for its AI-powered log analysis tools. By integrating NSHC's AI Pentester and LogSpect's LogEater, BRIDGED enhances its SOC capabilities to proactively address potential vulnerabilities.

Analyzing from the Attacker's Perspective

One of the service's key features is its innovative approach to bridging the divide between the Red Team (attack) and the Blue Team (defense). By adopting an attacker’s viewpoint for analysis, BRIDGED PURPLE SOC makes visible the gaps between potential attacks and existing defenses. This visibility aids in refining detection logic, improving monitoring operations, and enhancing analytics processes. The service encourages businesses that struggle to develop advanced SOC capabilities independently to engage in continuous monitoring, attack validation, and detection improvements, thereby elevating their security posture throughout the supply chain.

The Need for Enhanced Cybersecurity Measures

The proliferation of generative AI has led to accelerated cyberattacks, creating significant risks for organizations. Traditional methods of passive monitoring and annual vulnerability assessments are insufficient to keep pace with rapidly evolving threats, especially those that are stealthy or disguised. This emphasizes the crucial need for a proactive and strategic approach to SOC operations, which the BRIDGED PURPLE SOC embodies.

Key Features of BRIDGED PURPLE SOC

1. AI-Driven Practical Verification (Red Team)

The service utilizes NSHC's AI Pentester to verify external threats from the dark web and open-source intelligence (OSINT). By adopting the TLPT (Threat-Led Penetration Testing) model, it unveils attack pathways and defensive weaknesses that standard vulnerability assessments may overlook, empowering organizations to better prepare against potential risks.

2. Hybrid Monitoring with AI and Human Elements (Blue Team)

Using Elastic Cloud SIEM for real-time detection, the service collects logs, performs correlation analysis, and issues alerts. LogEater empowers SOC analysts to conduct long-term analysis of large datasets efficiently, ensuring that concealed and disguised attack signs are continuously monitored.

3. Attack-Defense Gap Analysis and Continuous Improvement (Purple Team)

By correlating findings from Red Team testing with the Blue Team's monitoring, BRIDGED PURPLE SOC identifies and analyzes gaps between attack simulations and actual defenses. AI assists in pinpointing areas for improvement in monitoring rules and processes. This cyclical feedback loop enhances the overall SOC operation by driving ongoing improvements in detection and response strategies.

Use Cases Across Industries

1. Manufacturing:
For manufacturers, the service can visualize external risks within the supply chain by utilizing AI Pentester to simulate potential attack vectors from overseas, partners, and suppliers. SOC analysts assess if these risks can be detected by their existing SOC, leading to tailored recommendations for necessary monitoring rules and responses.

2. Finance/Fintech:
In the finance sector, under stringent regulatory requirements, continuous verification and long-term log analysis are essential. BRIDGED PURPLE SOC delivers consistent verification processes guided by TLPT principles, utilizing LogEater for effective log management and analysis during incidents.

3. Supporting Companies Lacking Dedicated SOC Teams:
For companies without dedicated security personnel or a SOC, BRIDGED offers AI-enhanced monitoring, analysis, and improvement services. By combining human oversight with advanced AI analytics, this environment equips companies to engage in practical defense enhancements against threats.

Future Roadmap

BRIDGED plans to extend the automation of attack verification, log analysis, and detection rule enhancements over time. By integrating human judgment with AI capabilities, the aim is to create a SOC operation that swiftly adapts to evolving threats while continuously improving its defenses.

Upcoming Exhibition at AI NATIVE EXPO 2026

BRIDGED will showcase the BRIDGED PURPLE SOC at AI NATIVE EXPO 2026, taking place from June 10 to 12, 2026, at Makuhari Messe. Attendees can expect demonstrations of the service, including the LogEater engine integrated with Elastic Security, highlighting hybrid configurations and advanced log analysis features.

This service is pioneering a proactive approach to cybersecurity, creating a robust environment for continuous defense adaptation and resilience against emerging threats.
