Advantis Credit Union was a member-owned financial cooperative dedicated to its members’ economic success. Following its merger with Rivermark Community Credit Union, Advantis members and operations now continue under Rivermark, which remains a member-owned credit union.
Strengthening financial security with Microsoft Defender and Sentinel
Advantis Credit Union partnered with Atmosera to modernize its security operations and strengthen the protection of member data using Microsoft Defender and Microsoft Sentinel. Facing increasing cyber threats and limitations with a legacy SIEM, Advantis sought a modern, scalable security platform to improve visibility, response times, and compliance readiness.
Advantis Credit Union now operates as a division of Rivermark Community Credit Union following its acquisition.
