DTS Selects Netskope for Zero Trust with User-Centric Control

Founded in 1972, DTS Corporation, an independent systems integrator, has been supporting IT initiatives across the public and corporate sectors. As remote work became more widespread and cyber risks increased, the company sought to strengthen its own security while contributing to broader societal challenges as a total system integrator. As part of this effort, DTS adopted Netskope—a cloud-native security platform. By overhauling its VDI environment and visualizing all traffic through a Zero Trust approach, DTS has achieved both convenience and robust security. The company plans to share the knowledge it has gained through internal implementation with its clients going forward.

Adopting zero trust to strengthen security and address societal challenges—assuming nothing can be trusted

As part of its mid-to-long-term strategy “Vision 2030,” DTS envisions itself as a company that “challenges itself to deliver value beyond expectations” by 2030. The company offers comprehensive services from consulting and design to development, implementation, and operations, as well as business solutions and BPO (Business Process Outsourcing).

To realize this vision, DTS is leveraging cutting-edge technologies to develop new services and solutions based on the trust it has built with clients. Alongside DX, security is a critical theme in its business strategy. Prior to the pandemic, DTS had already adopted a company-wide VDI (Virtual Desktop Infrastructure) service due to concerns about endpoint protection beyond legacy firewalls. While this allowed for a smooth shift to remote work during the pandemic, several issues also emerged. Makoto Fukumoto, Director of Infrastructure in the Information Systems Department, recalls “First, the costs were high. Also, resources were tied to contract levels. While VDI worked well for office applications, users involved in development reported performance issues. Additionally, security was somewhat of a black box, with limited control over logs and traffic.”

Even post-COVID, remote work remains a key part of Japan’s work style reform. Amid rising cyber threats, there’s growing demand for safe and secure work environments, both in and out of the office. In 2021, DTS began implementing Zero Trust Security to reinforce its own protection and address societal security challenges as a total system integrator.

Netskope was the only solution that truly balanced convenience and security.

Netskope was the clear choice—balancing convenience and security

On the reasons behind adopting Zero Trust, Fukumoto explains “We wanted to not only solve existing VDI challenges but also incorporate advanced security. Zero Trust, which assumes no communication can be trusted, breaks away from traditional perimeter-based security. By leveraging the cloud, it provides comprehensive protection under a unified security framework.”

When choosing a Zero Trust product, Netskope was the obvious choice. DTS’s executives, with deep expertise in cybersecurity, had long recognized Netskope’s capabilities and strong track record.

Koji Shimojo, Section Manager of the Infrastructure Team in the Information Systems Department, shares why “As a systems integrator, our engineers use various cloud services and applications depending on their roles. Netskope provides detailed visibility into all traffic, enabling us to offer engineers flexibility in their app usage while maintaining proper oversight. In addition to granular log management, it allows user-based traffic control rather than just by IP. Netskope was the only solution that truly balanced convenience and security.”

Netskope’s user-based control allowed us to limit access to specific employees and maintain consistent environments across multiple devices, whether remote, in-office, or on client premises.

Flexible user-based control ensures security while meeting user needs

In April 2021, DTS decided to adopt Netskope and began migrating its thin-client and VDI environment to a Zero Trust model using Netskope. With an efficiently designed architecture, the company ensured a rapid deployment. From October 2021, the system was not only used internally but was also tested by business departments responsible for new services. Proof-of-Concept (PoC) efforts supported environment refinement.

Tatsuya Yamamoto, also from the Infrastructure Team, elaborates “Unlike standardized setups focused on recommended apps, our approach had to meet diverse internal needs. For applications that didn’t initially connect, we worked with agents and collected various data points to resolve issues. Netskope’s user-based control allowed us to limit access to specific employees and maintain consistent environments across multiple devices, whether remote, in-office, or on client premises.”

By April 2022, DTS had rolled out the Zero Trust solution company-wide. Typically, business divisions purchase devices themselves, but as part of awareness-building, the Information Systems Department provided pre-installed Netskope devices to internal influencers, sparking interest and encouraging adoption.

We also plan to fully utilize Netskope’s features like DLP (Data Loss Prevention) for monitoring file uploads and the Cloud Confidence Index (CCI) for evaluating cloud risks, to further enhance security and usability.

High praise for performance and usability—leveraging Netskope to further strengthen security

Netskope received strong positive feedback from users. “Being able to choose devices based on individual needs is a huge benefit. Unlike standardized thin clients, we can now support users who need high-spec machines. Complaints about device performance have vanished, and productivity has improved. Plus, unlike VDI, which requires connecting to a backend environment, Netskope works immediately upon powering on. It feels just like using your regular device—only in a secure environment,” says Shimojo.

In addition to improved security and convenience, DTS also reduced ongoing costs compared to its previous VDI service. Looking ahead, Fukumoto comments “Our next focus is on how to leverage communication logs to inform field-level actions. We also plan to fully utilize Netskope’s features like DLP (Data Loss Prevention) for monitoring file uploads and the Cloud Confidence Index (CCI) for evaluating cloud risks, to further enhance security and usability.”

DTS positions Netskope as a core foundation for realizing Zero Trust. Moving forward, the company intends to apply its in-house experience and expertise to help solve its clients’ security challenges.
