Case Study: Catholic Archdiocese of Seoul achieves enhanced threat protection across 360 churches with SonicWall

South Korean Religious Organization Protects Sensitive Information with SonicWall’s Next-Gen Firewalls

The Catholic Archdiocese of Seoul, which oversees 360 churches, needed to protect sensitive member and donation data while rolling out a new IT system across its parishes. The archdiocese turned to SonicWall, evaluating next‑generation firewalls, IPSec VPN, ZTNA and SMA solutions to obtain an economical, centrally managed security posture for both cloud and on‑premises environments.

SonicWall implemented an NSa 5700 with APSS (including Capture ATP sandboxing) at headquarters, deployed TZ Series firewalls across 360 locations connected via SD‑WAN, added NSM reporting and a CMS for 100 concurrent users, and used SMA/NSa HA appliances. The deployment delivered stronger protection (including zero‑day threat blocking), more stable remote access and easier administration — while reducing the overall security budget and maintaining high security across all sites.
