Answer-Bot Blocking for Live Exams
Scripted clients feed questions to outside solvers in real time, turning a proctored exam into a relay race.
What the attack looks like
Automation targeting online assessment is rarely a single bot. It is an operation: rotating proxies, realistic browser fingerprints, and pacing tuned to stay under naive rate limits. By the time the damage shows up in your dashboards, the operator has already moved on.
Why generic defenses fall short
Simple rate limits and CAPTCHA walls catch careless scripts and punish real candidates. Modern bot operations solve challenges in bulk through farms and spread requests across thousands of addresses.
How ExamFence stops it
ExamFence layers behavioral analysis, device fingerprinting, and network intelligence into a single risk score per session. Decisions happen before the request reaches your application, and scores adapt as operators change tactics. You keep the value of your scores; candidates never notice.
