NTT DOCOMO BUSINESS WideAngle AI SOC (AI Agent log analysis with managed SOAR auto-response)

What it does

WideAngle AI SOC (launched May 20, 2026) is part of NTT DOCOMO BUSINESS's WideAngle managed security services. Customers send three types of logs (endpoint, network and authentication) and security alerts to Microsoft Sentinel. NTT's in-house AI Agent ('AI Advisor') checks the incidents in Sentinel on a regular cycle, runs cross-log correlation analysis that NTT says previously took analysts one to two hours, and returns an analysis report to Sentinel. Based on the agent's results, Sentinel applies automatic responses using NTT's own SOAR playbooks (managed SOAR), built from its security operations experience. NTT security specialists support customers with questions about results. NTT says it will widen the scope of automatic response over time. The service is aimed at Japanese enterprises without in-house SOC skills; it is a managed service on Microsoft Sentinel rather than standalone software. Timing claims are the vendor's. Pricing is not published (contact NTT DOCOMO BUSINESS sales).

Alternatives

• 
  7AI agentic security platform — Boston-based agentic security platform where swarms of specialised AI agents categorise, investigate and reach a determination on every alert, escalating only what needs a person, with optional managed service (PLAID ELITE).
• 
  Abnormal AI Security Mailbox (Abnormal AI for Government) — Autonomous agent for email security operations that triages user-reported emails, removes related malicious campaign messages across the organisation and replies to reporters; included in Abnormal AI for Government, which is FedRAMP and GovRAMP Moderate authorized.
• 
  Adaptive Security Agentic Email Security and Phish Triage — API-based 'agentic email security' that re-analyses inbound mail after native filtering with ML and LLM reasoning and removes confirmed threats across every inbox automatically (configurable human-in-the-loop thresholds). AI Phish Triage classifies employee-reported emails and acts on them, feeding Adaptive's simulations and awareness training.
• 
  Aikido Attack AI Pentesting — Belgian autonomous AI pentest: many agents map the app, test attack paths and re-exploit each finding to confirm it, with a same-day audit-grade report.
• 
  AIpentix (agentic continuous security testing and agentic red teaming, by Swipergy) — German continuous security-testing platform with an AI agent that signs in to the customer's application on its own, chooses follow-up checks and documents attack paths, with every tool run evidenced. Findings are grouped into remediation actions with owners, deadlines and Jira sync, and retests confirm fixes. Agentic red-team campaigns (recon, access, lateral and report agents led by human red teamers) are also offered for TIBER-EU and DORA TLPT style testing.
• A
  Andesite Human-AI SOC (Azimuth for Government) — Agentic SOC platform with configurable agents for alert triage, enrichment, investigation and remediation under analyst oversight; its government offering is FedRAMP High authorized.
