Most real security incidents don’t start with a loud alert. They start quietly, with something that could be normal… or could be the first sign of trouble. Let’s walk through a realistic example. No malware samples. No red-team theatrics. Just something that happens on real machines every day.

When people think about endpoint security, they usually picture laptops and desktops. Servers tend to fade into the background. They’re stable. They’re rarely touched. They “just work.” And because of that, they’re often the least visible, and most dangerous, endpoints in an environment.

Most endpoint security still revolves around one core idea: identify something known to be bad, then block it. That approach works, until it doesn’t. FortiSense was built around a different question: What signals appear before something is clearly malicious? This post explains how FortiSense detects risk without relying solely on file signatures, and why that matters in modern environments.

Most security tools tell you that something happened. Very few explain why. That difference matters more than most people realise. FortiSense is built around the idea that alerts should be understandable by the people who actually have to act on them, not just security specialists. This post explains what “explainable alerts” mean in practice, and why they’re essential for small teams.

For many small teams, endpoint security looks deceptively simple. Built-in antivirus is enabled. Updates are automatic. Alerts are rare. Most of the time, nothing appears to be wrong. And that’s exactly the problem. FortiSense exists because there’s a large, uncomfortable gap between what traditional antivirus provides and what full enterprise EDR demands, and most organisations are stuck in the middle.
