Case Study: National Instruments achieves 95–99% spam blocking and global email protection with Proofpoint Enterprise Protection

National Instruments - Customer Case Study

National Instruments, a global engineering company with thousands of user inboxes across 44 countries, needed to replace a failing home‑grown anti‑spam system. The company faced very high spam volume (roughly 80% of mail) and required a flexible, user‑friendly solution that fit diverse regional and role‑based preferences while minimizing false positives.

Proofpoint Enterprise Protection was piloted (initial 50‑user audit then company‑wide test) and identified more than 95% of incoming messages as spam—reaching about 99% accuracy for most users—with only 2% marked “probable spam.” After full deployment, National Instruments achieved superior spam blocking, reduced risk to downstream systems, and received consistently positive employee feedback as spam essentially disappeared overnight.
