Case Study: Leading Global Bank cuts $90M in excess IT costs with Imperva Data Security

Global Bank Cuts $90 Million in Excess IT Costs

One of the world’s largest banks, with operations in 40+ countries and more than 38 million customers, faced mounting regulatory pressure (MAS TRM, RBI, SOX) and tried to meet requirements using built‑in database auditing. That approach introduced three hidden costs—about a 20% database CPU hit requiring extra hardware/software, massive log storage, and increased IT headcount—and produced inconsistent, audit‑failing reports, pushing the estimated cost of making the in‑house solution work toward $100 million.

Replacing the in‑house system with Imperva Data Security automated auditing and protection across 3,000+ databases, cutting database CPU overhead by ~90 (bringing load to ~2%), slashing storage needs (saving roughly $29M), and reducing labor by about 70% (~32 FTEs). Total cost of ownership fell from ~$110M to ~$20M, delivering over $90M in savings while improving reporting, compliance and database protection.
