Zero Trust is a security framework that requires all users and devices to be authenticated, authorized, and continuously validated before being granted access to applications and data. It operates on the principle of 'never trust, always verify'.

SASE (Secure Access Service Edge) is a cloud-native architecture that combines networking and security functions into a single, integrated cloud service. It aims to provide secure and fast access to applications and data for users regardless of their location.

What were the main challenges Gurunavi faced before implementing Zero Trust?

Gurunavi faced challenges in visualizing and controlling cloud service usage, addressing shadow IT, and managing traffic congestion with their existing on-premises proxy and VPN environment. They also needed to ensure secure access for employees working in a hybrid model.

What are the key benefits Gurunavi achieved after implementing the Zero Trust foundation?

Gurunavi achieved enhanced governance of cloud service utilization, a secure and convenient hybrid work environment, resolved communication congestion, improved performance, eliminated vulnerabilities by moving away from VPN, and reduced operational costs by approximately 40%.

What role did Tokyo Electron Device (TED) play in this project?

TED provided comprehensive support throughout the project, including product selection, Proof of Concept (PoC) design and technical verification, production deployment, and ongoing operational support through their Netskope Risk Assessment Report Service.

Tokyo Electron Device supports Gurunavi's zero trust foundation, leading to a 40% reduction in operational costs.

Tokyo Electron Device, Ltd. (Headquarters: Shibuya-ku, Tokyo, President & CEO: Atsushi Tokushige, hereinafter TED) has supported the construction of a zero trust foundation utilizing the security platform "Netskope One" in Gurunavi, Inc.'s (Headquarters: Chiyoda-ku, Tokyo, President & CEO: Akio Sugihara, hereinafter Gurunavi) network/security foundation renewal project to support hybrid work. As a result, Gurunavi has established governance for cloud service utilization and achieved approximately 40% reduction in operational costs by moving away from the conventional VPN environment. For details, please visit the Tokyo Electron Device Gurunavi Netskope Implementation Case Study page.

Gurunavi aims to create an environment where diverse talent can demonstrate their individuality and maximize individual and organizational performance. From the perspective of work style reform, they are promoting hybrid work that supports behavioral change and are working towards implementing zero trust to achieve a business environment where cloud services can be accessed safely anytime, anywhere. This has resulted in the following benefits: ● Visualized cloud service usage and strengthened governance ● Maintained a secure and convenient business environment under hybrid work ● Resolved communication congestion and improved hybrid work performance ● Eliminated vulnerabilities by moving away from the aging on-premises VPN, reducing operational costs by approximately 40%

Netskope's SASE Enables Cloud Visualization and Zero Trust Implementation In the spring of 2020, Gurunavi introduced "Netskope One" as a SASE platform to visualize and control cloud service usage. Following the spread of remote work during the pandemic, they aimed to realize a zero trust network that could apply the same security policies both inside and outside the company, and decided to transition from their traditional VPN to "Netskope Private Access (NPA)".

TED Provides Integrated Support from PoC to Production Deployment and Operation TED, having built a relationship of trust with Gurunavi through Netskope implementation and subsequent operational support, provided integrated support for the NPA implementation project, covering product selection, PoC (Proof of Concept), production deployment, and operational phases. ● Support for PoC (Proof of Concept) design and technical verification ・ TED's dedicated SE participated in the PoC, accompanying the process from requirements definition to design and verification. ・ Completed technical verification necessary for production deployment within the approximately 2-month PoC period. ● Operational support through TED's "Netskope Risk Assessment Report Service" ・ Visualization of unauthorized cloud service usage and behavior based on Netskope log analysis. ・ Policy optimization and cost-effective improvement proposals based on the latest Netskope technological trends.

【Customer Comments】 Yuji Tsushima, Deputy Section Chief, Infrastructure Service Section, Development Department, Development Division, Gurunavi, Inc. "As cloud service utilization increased, we felt limitations in addressing shadow IT and traffic congestion with our existing on-premises proxy. Through Netskope's visualization and control of cloud usage, along with TED's log analysis reports, we have established governance for cloud service utilization. Furthermore, by migrating to Netskope Private Access, we have achieved the construction of a zero trust environment that is seamless both inside and outside the company. We intend to continue our efforts towards realizing 'Secure Hybrid Work' by refreshing our network configuration to a simpler structure combined with high-quality internet connectivity, and by expanding deployment to devices other than PCs."
