Building a real-world IAM system: centralized vs. distributed

Raise your hand if you’ve ever been locked out of your banking app, a hotel room, your work computer, your car, your Gmail… the list goes on. You know the reason your access was blocked was because you either forgot your keys/password or had the incorrect login credentials.

How Nightfall.ai simplified their architecture for metadata storage

For organizations that want to avoid risk the first step is often to safeguard their most important asset: data. Data loss usually happens by accident (primarily human error and system failures) and not because of malicious intent or bad actors. Maybe an employee neglects to update their software, or an entire cloud region goes down, or there’s an unexpected influx of traffic that the company wasn’t prepared for – we’ve all heard of or have been part of these stories.
