For nearly two decades, Shinobi technology has been used in Japan by customers such as Kamiamakusa City, Nippon Expressway Company and the National Defense Academy of Japan.  As the market leader in cybersecurity in Japan,  we have a long and proven track record of protecting sensitive data from leakage and theft and preventing cyberattacks from destroying mission critical systems.  

Customer Spotlight: Ichihara City Government

Facing Tokyo Bay, Ichihara City is the largest city in Chiba Prefecture with a population of 280,000 and the second largest (in revenue) industrial area in Japan.  Ichihara City is a major manufacturing and shipping center as well as home to the most golf courses of any Japanese city, and the Japan League soccer team JEF United. Each of the 2000 PCs used by the city government staff are protected by Evolution DLP.

Deployment Scope: 2,000 PC’s

Ichihara City decided to employ strong security in its network system when a new citizen numbering system was enacted. In addition, a controversial data leakage incident was reported in news that prompted them to take immediate action. Ichihara City decided to implement Evolution DLP as a secure system that encrypt files so they are never read outside their network without their intent.


  1. Thin client environment
  2. Invisible to users
  3. Easy to deploy and compatible with existing systems
  4. Meets new citizen numbering platform requirements
  5. Office and SharePoint compatibility
  6. Full traceability and forensics
  7. Integration with Active Directory
  8. Small footprint; no encryption at rest


With the enactment of a new citizen numbering system with additional data regulations, Ichihara City decided to upgrade their security solution. The reports of several controversial data leakage incidents in the news only increased their resolve to take action and implement Shinobi Evolution DLP, a system that automatically encrypts all files that leave the network unless intended.
Simultaneously deploying network separation and thin client infrastructure, combined with a 1-month deadline, made it critical that the security solution would be easy to deploy and have minimal effect on the performance of these new systems.


During the evaluation phase, Ichihara City confirmed that Evolution DLP invisibly protected all files regardless on their various environments, from their main network systems to SharePoint and the documentation management system, without any additional changes to the existing systems. Within the network, or “Trusted Zone”, the files remain in cleartext, leaving existing workflows and system functions, such as previewing and full-text searching data on browsers, gathering CSV data, and other daily use cases from both users and administrators, unaffected.

From the IT Administrator point of view, the SDS deployment was easy and straightforward, with no interruptions to the end user workflow between the time of installation and configuration to the time when employees began to use SDS. The Forensic logs provided detailed evidence and history of all user operations, both good and bad. The full deployment, from evaluation to production, was one month.


For end users the daily workflow has changed slightly in order to enable a higher level of security, and this was broadly seen as help in protecting them from making mistakes that put the organization at risk. This workflow requires data to go through a Release Folder before it can be removed from the office, a procedure that helps employees recognize and appreciate what it means to take confidential data outside of the workplace. Employees who have sent email attachments to incorrect email addresses in the past can now feel secure, knowing that SDS will protect them from such mistakes.

“Just as the new social security system and regulations were about to be implemented throughout Japan, there was also a major cyberattack of the Japan Pension Service that leaked a shocking 1.25 million people’s personal information. We decided to take immediate action and looked at several proposals, and decided that the Shinobi technology was the best solution for us.”

Mr. Takahiro Kiuchi, Manager, IT Promotion Information Management Division

4000 PCs Protected

Yahoo! Japan is the most visited website in Japan.

“At Yahoo! JAPAN, more than 19 million users log in each month and we are very focused on managing personal information securely. We used to only monitor our networks, but with SDS, we can monitor our client PCs for suspicious or unauthorized actions. ”

Mr. Katsuhiko Yasuo, Chief Manager, Information Security Department

8000 PCs Protected

East Nippon Expressway Company Limited (NEXCO East) relies on SDS for data leakage prevention for its motor highway and expressway operations in eastern Japan where over 57 million people (approximately 45% of Japanese residents) reside.

“At NEXCO East, we concluded that SDS excels due to its: (a) streamlined data leakage prevention that allows sharing of data within the organization in plain format while automatically encrypting outbound data; and (b) comprehensive log collection feature which not only collects access logs but also operation logs.” 

Mr. Takanori Tachibana, Manager, Information Systems Dept.
