Frequently Asked Questions

What information can be extracted from user agents?
User agents contain browser name and version, operating system, device type, rendering engine, and various capabilities. Our parser also detects bots and potential security issues.
How accurate is bot detection?
Our bot detection includes patterns for major search engines, social media crawlers, and common bot indicators. However, sophisticated bots may evade detection by spoofing user agents.
Can user agents be spoofed?
Yes, user agents can be easily modified or spoofed. They should not be relied upon for security decisions, but are useful for analytics and content optimization.
What security vulnerabilities are detected?
The tool identifies outdated browsers with known security issues, particularly old versions of Internet Explorer, Chrome, and Firefox that may have unpatched vulnerabilities.
Does the tool work with bulk analysis?
Yes! Enable bulk mode to analyze up to 20 user agent strings at once. Simply enter each user agent on a separate line.
