Card fraud in neobanks doesn’t start at the transaction—it builds across onboarding, login, funding, and behavior signals. The Novo case shows why measuring only chargebacks is flawed. Strong fraud systems balance loss prevention with user experience by tracking false positives, recovery rates, and lifecycle signals. The goal isn’t blocking more—it’s making smarter decisions with less friction.

Despite AI coding tools generating more code than ever, engineering productivity lags because these tools excel at building, not debugging or operating systems.

AI coding tools have transformed the creative process of writing code, enabling rapid prototyping and automation. Yet productivity gains remain elusive because AI struggles with debugging, testing, and operationalizing software. Current models excel at building “up” but fail at the scientific, investigative “building down” required for reliable production systems. Future tools must bridge this gap.

If you’re still not sure who’s the best fit for you, here’s how I view each vendor: Choose SecurityMetrics if: You need an expert, affordable test that fits your budget and compliance needs. Choose Cobalt if: Your developers are shipping code weekly and need a real-time feedback loop. Choose Bishop Fox or Rapid7 if: You are a primary target for nation-state actors.

Free VPNs aren't free. Someone pays for every server, every IP address, every gigabyte of traffic. When you don't pay with money, you pay with your data, your bandwidth, or sometimes your identity. To make you understand this better, I’ll break down the actual infrastructure economics with real numbers and documented cases in this article.
