Case Study: Schaefer Kalk achieves comprehensive EDR visibility and averts ransomware with Vectra AI Inc.

How Global Limestone Leader Schaefer Kalk Overcame their EDR Visibility Gaps

Schaefer Kalk, a 160‑year‑old family‑owned global lime producer, needed to strengthen cybersecurity across its network, hybrid and cloud environments. Their existing EDR (Cybereason) left visibility gaps—missing attack chains and unmonitored systems—which limited threat detection and slowed incident response.

They implemented Vectra AI’s Attack Signal Intelligence XDR with Managed Detection and Response and worked with SVA for deployment, gaining visibility into virtual environments and Microsoft 365/Entra ID activity. Vectra’s detections and MDR team identified and helped neutralize a serious attack that bypassed the EDR, reducing detection latency, avoiding potential ransomware losses, and delivering measurable cost savings and operational efficiencies.
