· The Importance of Preventing Personal Information Leaks

Recent personal data breaches are increasingly caused not only by cyberattacks but also by everyday operational oversights such as email misdelivery, unattended documents, and loss of USB drives or devices.

Data leakage risks exist across all industries and company sizes. Inadequate policies or insufficient checks can easily escalate into major incidents.

· Sample Content from the Guide

This guide includes a 69-item checklist designed to evaluate an organization’s personal information protection framework.

It comprehensively covers areas including paper document management, email handling, mobile devices, computer usage, external storage media, network usage, and physical security. By simply marking each item as ✓ or ✗, companies can quickly identify vulnerabilities and improvement opportunities.

The guide also clearly explains recommended improvement steps based on the results and how these relate to P-Mark and ISMS (ISO27001) compliance.

Since its founding, our company has consistently focused on ISO consulting under the service philosophy of 'minimizing internal workload so that clients can focus on their core business.'

Our current service model, which includes not just advice but also hands-on operational support, originated from client requests such as, 'We’re managing ISO compliance, but internal resources are limited and procedures are cumbersome—can you handle the work on our behalf?'

While our service is often misunderstood as 'outsourcing everything,' our true value lies in clearly distinguishing between 'decisions the client must make' and 'tasks best handled by professionals,' thereby reducing overall burden. For example, when building a house, you express your vision but don’t hammer the nails yourself. We apply the same principle to certification. Going forward, we will continue striving to meet diverse client needs as trusted experts in ISO and P-Mark compliance, embracing change without hesitation.
