Tokuji Computer Service Launches "TOPLink," an Enterprise IT Foundation for the AI Era, Integrating Fragmented IT Operations for SMEs
Tokuji Computer Service has launched "TOPLink," a closed-network-centric IT platform designed to integrate fragmented IT operations for small and medium-sized enterprises (SMEs) in the AI era. This platform aims to centralize network, security, server, backup, and AI environments, addressing challenges such as IT talent shortages and ransomware threats.

As AI utilization advances, enterprise IT demands a foundation that allows for secure data utilization. However, in small and medium-sized enterprises (SMEs), networks, security, servers, backups, and AI environments are often introduced individually, leading to fragmented and person-dependent IT management.
Tokuji Computer Service Co., Ltd. (Headquarters: Shinjuku-ku, Tokyo; Representative Director: Koji Tokunaga) announced on May 7, 2026, the launch of "TOPLink (Tokuji Private Link)," an enterprise IT platform centered on a closed network (a corporate-exclusive network that does not go through the internet) to address these challenges.
TOPLink is redesigned as a next-generation platform that supports enterprise IT in the AI era, based on the company's approximately 15 years of experience in closed network operations from its predecessor service.
Why an Integrated IT Platform is Needed Now
In recent years, the IT environment surrounding SMEs has seen the following simultaneous changes:
Rapid expansion of AI utilization needs (Microsoft 365 Copilot, in-house RAG, AI agents, etc.)
Increase in ransomware damage and growing demands for recovery systems
Difficulty in continuous operation due to IT talent shortages
Complication of multi-site operations (hybrid work, expansion of sites, cloud usage)
An era where SMEs are also required to comply with security and AI governance
These changes cannot be addressed individually, necessitating a foundation that can operate networks, security, servers, and AI environments as a single integrated unit. TOPLink is an IT platform redesigned for SMEs in response to this contemporary background.
Development Background: Challenges Arising from Fragmented Operations
Traditionally, corporate IT environments often involved individual introductions of VPNs, UTMs, clouds, backups, and AI environments, leading to challenges such as fragmented operational management, incident response, and security policies. Operating each with different vendors and contracts complicates responsibility demarcation and recovery flows, significantly increasing the operational burden, especially for SMEs with limited dedicated IT staff.
Specific challenges for SMEs include:
Network and UTM management being fragmented across each site
Operations becoming complex due to VPN-centric configurations
Aging in-house servers
Concerns about ransomware countermeasures and recovery systems
Desire to utilize AI but facing challenges in internal data utilization and security
Difficulty in continuous operation due to IT talent shortages
TOPLink integrates all of these on a closed network, unifying vendors, contracts, and operational management, thereby realizing a sustainable IT foundation for SMEs. It is positioned not merely as a line service, but as a service that provides a "foundation for safe and continuous operation of overall enterprise IT."
Representative's Comment
When speaking with SME customers, I have seen numerous cases where they had no choice but to consider networks, servers, backups, security, and even AI separately, resulting in fragmented operations. TOPLink was born from the desire to integrate these on a closed network and provide a foundation that can be safely and continuously used even with limited IT personnel. Leveraging our approximately 15 years of experience in closed network operations, we will support the IT foundation of SMEs in the AI era.

Overview of TOPLink
TOPLink (Tokuji Private Link) is a platform that connects customer sites and our data centers via a closed network, and on top of that, provides the following integrated IT services:
Closed network internal network
Internet threat countermeasures
Server operation
Ransomware countermeasures backup
VPN connection
In-house AI utilization foundation
Microsoft 365 / Azure integration
By providing everything from network to IT infrastructure and AI utilization as a single unit, TOPLink helps organize fragmented enterprise IT operations and supports the construction of a foundation that anticipates future AI utilization.
Main Features of TOPLink
Feature 1: Integrated IT Foundation for Multi-site and Single-site Operations
TOPLink's primary objective is to integrate the IT environments of companies with multiple sites, such as headquarters, branches, sales offices, factories, and field bases, with a closed network at its core. It can integrally organize and operate elements that tend to be fragmented across each site, such as networks, VPNs, UTMs, internet connections, servers, backups, and AI utilization environments, thereby supporting the reduction of burdens related to incident response, security management, and backup operations. It can also be introduced by companies with only one site.
Feature 2: Secure Inter-company Communication via Closed Network
