Growing Interest in Zero Trust Networks Among Large Enterprises

In recent years, the network environment surrounding businesses has entered a significant transition phase. With the rising sophistication of cyberattacks, coupled with the growth of telecommuting and expanded cloud services, traditional security models are increasingly being challenged. This scenario has brought the concept of Zero Trust Networks, which involves verifying and controlling all access, regardless of whether the user is inside or outside the organization, into sharp focus.

According to the 2025 Corporate Network Services Customer Satisfaction Survey conducted by J.D. Power Japan, there is a notable increase in awareness surrounding the migration to Zero Trust Networks. Among large enterprises, 26% identified the shift to this model as a key challenge, while 8% of small and medium-sized businesses (SMBs) shared the same sentiment. The trend from the past five years shows a consistent increase in interest among large enterprises, indicating that this focus is likely to continue to grow.

High Satisfaction Levels for Zero Trust Services

Although the percentage of companies utilizing Zero Trust Network-related services remains below 10% in both the large enterprise and SMB markets, those that have adopted these solutions report significantly higher satisfaction levels. Enterprises using Zero Trust-related services scored an average satisfaction rate that exceeded the overall survey average by 21 points.

In particular, factors such as service content/quality and sales/support responses received high marks. The evaluation for service content/quality noted the robustness of various options and menu services, while sales and implementation support were praised for their ability to propose adequate solutions related to networking and associated services. This indicates that the content of security-related services and customer proposals has notably contributed to improved satisfaction.

Going forward, ensuring the safety of corporate networks will remain a critical issue for business continuity. Telecommunications companies must not only enhance their security-related offerings but must also show flexible and sophisticated proposal capabilities that cater to the use of cloud services and diverse working styles. By accurately grasping customer needs, companies can design services and provide implementation support that bolster safe and secure network operations.

Overview of J.D. Power’s 2025 Customer Satisfaction Survey

J.D. Power's survey, now in its 24th iteration, assesses customer satisfaction regarding network services provided by telecommunications operators to businesses across Japan.

To measure general satisfaction levels, several factors were established, each weighted based on its influence. The rankings indicated that service content/quality accounted for 41% of overall satisfaction impact, sales/implementation accounted for 31%, while cost contributed 24% and problem/resolution support account for the remaining 5%.
