Case Study: Xcel Energy strengthens email security and protects critical infrastructure with Proofpoint

Xcel Energy blocks 430,000+ threats with Proofpoint

Xcel Energy, a major energy provider, faced a dramatic increase in AI-sharpened email attacks targeting its critical infrastructure. With a 902% rise in threats, its existing multi-vendor security approach lacked the efficacy needed to protect its 28,000 employees. The company partnered with cybersecurity vendor Proofpoint to strengthen its defenses.

By fully deploying Proofpoint's layered email security, including Enterprise Email Protection and Targeted Attack Protection, Xcel Energy achieved a 99.99% threat detection rate. Proofpoint blocked over 430,000 advanced threats in a single quarter and reduced manual abuse mailbox reviews from thousands per month to just six. This measurable impact freed the security team to focus on higher-level threats and drove significant behavioral change across the organization through executive engagement.
