TOKYO - November 4, 2025 - Internet Initiative Japan Inc. (TSE Prime: 3774), one of Japan's leading Internet access and comprehensive network solutions providers, today announced the immediate availability of IIJ Security Doctor , a new service consisting of hands-on, side-by-side assistance with corporate security measures and operations, provided by IIJ security experts. In this service, security experts equipped with wide-ranging experience and knowledge analyze issues based on the customer's system environment and characteristics of operations, and study appropriate solutions. In collaboration among experts in such fields as networking, cloud, and email, the team provides support from planning and implementing measures to ongoing strengthening of security. Customers benefit from one-stop advisory on security issues across the entire enterprise, while being sure to implement the full management cycle from visualization to strategy studies and implementation of measures. Moreover, this service is vendor-neutral and offers the flexibility to select and implement the most optimal measures, without being limited to specific products or solutions.
IIJ aims to help people achieve digital transformation (DX) through its enterprise IT environment DXP (DX Platform), for accelerating business transformation with DX. The role of IIJ Security Doctor is as a security core underpinning the safety of these efforts.

Background

Along with the growing sophistication of cyberattacks, including supply chain attacks and ransomware, risks such as "shadow IT" -- unauthorized use of the cloud or other IT resources -- and deliberate, malicious internal leaks of information, have made security measures more complicated and expanded the areas needing such measures. Responding effectively to these threats therefore requires expertise in a wide variety of areas, exacerbating the shortage of security personnel. Lately, along with addressing immediate challenges, a growing number of companies have been investing in security from a medium- to long-term view, further complicating the process of devising appropriate policies on security measures while taking into account the overall balance of the measures, characteristics of the industry and business, the management benefits of the investment, and various other factors. In response to this situation, IIJ has launched this service, as a partner working side-by-side with the customer, and drawing on the knowledge gained from developing and operating IIJ's existing security services, to help customers implement optimal measures from a comprehensive viewpoint and strengthen their security.

Major features of the service

Realizes security measures optimized to each customer

Based on a thorough understanding of the customer environment, IIJ's Security Doctor in collaboration with its experts and analysts in each field proactively propose highly effective measures. These proposals are made from a neutral standpoint, in support of security measures that Security Doctor judges to be appropriate in light of the customer's issues and overall situation, without being tied to particular security vendors or products.

Carries out ongoing security measures

It is essential that security measures be carried out through ongoing efforts rather than as one-time measures. Throughout each phase of the security administration process, from security assessment and advisory to strategy studies and implementation of measures, support is provided working side-by-side with the customer, strengthening security measures on an ongoing basis and not just as temporary problem-solving. Through this ongoing support, in addition to reducing management risks such as information leaks or suspension of operations, support is provided also for making security investment decisions from a medium- to long-term viewpoint.

Support cost optimization

Unlike support services provided by permanently on-premises security personnel, Security Doctor provides support as needed, geared to the nature of the customer's issues and status of studies. This means the service is available at optimal cost, without wasted resources. The customer can concentrate on security operations and strategy decisions, while seeking guidance from IIJ experts as needed regarding information gathering or studying of strategy and measures.
