We’re an agile business that dreams big, has the resources to deliver big and the credentials to back it up, as we were the first major bank to go all in on AWS.

As well as agility, Capital One is a company that puts customers at the centre of everything we do, and consequently, protecting customer data is our core focus. Their security is our responsibility and we protect the trust that our customers put in us on a 24/7 basis. Our Configuration Compliance team focuses on maintaining the hardening standards, assessing security posture, processing and reporting the findings of hundreds of thousands of assets across the Capital One enterprise.
