Zvelo

Zvelo is a cybersecurity intelligence company that maintains a massive, real-time database of URL classifications. Their crawlers systematically visit websites to analyze content, structure, and security posture, which is then used by network security vendors, SASE providers, and ad-tech platforms to enforce safety policies. By categorizing the web into hundreds of distinct topics and threat levels, Zvelo enables organizations to block malicious domains and ensure brand-safe environments for digital advertising.

The bot crawls the internet to populate the zveloDB™ URL database, which serves as the backbone for their real-time classification engine (zveloCAT™). By analyzing page content, the bot identifies potential security risks like phishing, malware, or inappropriate content, allowing security products to make informed blocking decisions. Website owners can verify the bot's activity by checking the source IP against zvelo's published infrastructure or by reviewing the User-Agent string provided in their official documentation.
