As SaaS utilization continues to expand, especially with the spread of remote work and the progress of digital transformation (DX), cloud services and SaaS have become critical infrastructure for business operations. SaaS platforms such as Microsoft 365, Google Workspace, Slack, Salesforce, and Box enable messaging, information sharing, file management, and collaborative editing in the cloud, helping teams work more efficiently. As a result, many companies are accelerating the migration of data previously managed on local folders and on-premises servers to the cloud, enabling more flexible work styles that are less constrained by location and time. At the same time, the risk of losing important data is increasing. While centralized cloud management is convenient, storing data in the cloud does not automatically guarantee data protection. In addition to human error, accidental deletion, insider misuse, and ransomware or other cyber attacks, data loss and business interruption can also occur due to SaaS provider failures or service outages. In many SaaS offerings, responsibility for data protection is considered to lie with the user, meaning companies must implement proper backup measures themselves. This is especially important for file-sharing SaaS such as Box, where materials like sales decks and contracts may be mission-critical. Organizations need risk controls that consider both internal and external threats. SaaS data backup is also an important topic from the perspective of obtaining and operating ISMS certification. This seminar will explain, with concrete examples, how to reduce critical data loss risks in SaaS environments by using the SaaS backup solution SysCloud. SysCloud helps securely back up SaaS data used by enterprises and enables quick recovery to required recovery points. By keeping clean backup snapshots and supporting point-in-time recovery, it is possible to maintain business continuity even if a SaaS failure or data loss occurs. The seminar is
