Below is the list of blog posts with the “Financial services” tag.

Every telemetry vendor’s demo runs on the same infrastructure: a clean, cloud-native, container-friendly stack where a modern agent drops in and just works. Then you go back to the bank you run day to day, where a mainframe still clears transactions, an IBM i (AS/400) system has been in production for decades, and a core-banking platform speaks a log format no off-the-shelf agent has heard of. That gap between the demo and the data center is where audit blind spots live.

When an auditor sits down with your team, they don’t ask whether you have a SIEM. They ask you to prove something: show me every privileged access event on this system for the last twelve months, timestamped, complete, and unaltered. Compliance in financial services isn’t a posture; it’s an evidence problem. And the moment you treat your SIEM as the place where evidence lives, you’ve put your audit trail on the most expensive, most volatile, and least complete layer of your stack.

Most security leaders can tell you their SIEM bill to the dollar. Far fewer can tell you, line by line, what they’re paying for. That’s a problem because in financial services, that bill grows faster than the security coverage it’s supposed to buy. Let’s break it down. The bill is a function of volume, and volume is not your friend Ingestion-priced SIEMs charge by how much data you send. That makes your security budget a direct function of log volume.
