Nayoro City General Hospital 様

製品：AppGuard Server
業種：Healthcare (Hospital)
Scale: Approximately 359 beds

As Japan’s northernmost emergency and critical care center, Nayoro City General Hospital has long been proactive in leveraging ICT technologies—for example, by building a network that connects medical institutions across northern Hokkaido and enabling remote triage for emergency patients. In recent years, following a series of ransomware incidents affecting hospitals throughout Japan, the hospital felt a strong sense of urgency that such threats were “by no means someone else’s problem.” Recognizing the importance of an approach that ensures medical services continue even if an intrusion occurs, the hospital chose AppGuard, deploying it on about 70 servers that support its hospital information system.
