NTT DOCOMO Business embeds managed security — including network-as-a-service with built-in protection — into its global telecom and IT infrastructure for large enterprises.

NTT DOCOMO Business is the global enterprise ICT and network services arm of Japan’s NTT Group. While its primary business is telecom and managed IT infrastructure rather than dedicated cybersecurity, it operates a substantial managed security services practice — including threat monitoring, managed detection, and secure network architecture — delivered as part of its global connectivity and IT services portfolio.
A notable recent offering is docomo business RINK, a network-as-a-service (NaaS) platform with security built into the network layer rather than bolted on afterward; RINK was named the Asia-Pacific winner of Gartner’s “Eye on Innovation Awards” for Communication Service Providers in 2025, the first time a Japan-based company won that award. NTT DOCOMO Business also won “Pinnacle Partner of the Year” and a strategic-win award from Palo Alto Networks’ 2025 Asia Pacific and Japan Partner Awards, reflecting deep integration of third-party security technology into its managed offerings.
As part of the much larger, publicly listed NTT Group, this profile covers NTT DOCOMO Business’s managed security and secure-NaaS offerings specifically — a genuine, analyst-recognized capability — rather than the parent telecom’s business as a whole.
Innovation Matrix Assessment
Building security directly into a NaaS platform (RINK) is a meaningful architectural step, recognized by Gartner as an APAC innovation-award winner in 2025.
Bundled managed security and secure networking reduce integration burden for large enterprises already buying NTT connectivity and IT services.
Global telecom scale plus Palo Alto Networks partner-of-the-year recognition in 2025 shows real commercial depth in the managed security channel.
As part of a massive, publicly listed global telecom incumbent, this offering improves on bundled security delivery but does not fundamentally change how enterprise security is architected.
Analyst recognition (Gartner) and vendor partner awards (Palo Alto Networks) provide credible third-party validation for a large-scale managed offering.
Embedding security into network infrastructure by default is a durable, sensible direction as enterprises consolidate network and security purchasing.
Why CISOs Should Care
Lets large, multinational enterprises get managed security and secure network-as-a-service bundled with their existing global connectivity relationship rather than sourced separately.
What Makes It Different
Builds security into the network layer itself (RINK) rather than treating security as a bolt-on to a separately purchased network service.
The Matrix Verdict
53/100 — INCREMENTAL INNOVATOR
A credible, analyst-recognized managed security capability inside a much larger telecom incumbent — solid operational value, limited by its scale from being disruptive.
Editorial Note: Claims vs. Verified Findings
This profile covers NTT DOCOMO Business's managed security and secure-NaaS offerings specifically, not NTT Group's broader telecom and IT services business.
