US Patent 11871235 Secure URL shortener for character-limited messages

Aspects of the disclosure relate to providing secure shortened URLs in character-limited messages. A computing platform may receive one or more character-limited messages sent to a user device. The computing platform may detect a URL within the one or more character-limited messages for replacement and generate a shortened URL corresponding to the detected URL, wherein a domain of the shortened URL is hosted by the message security system. The computing platform may then modify the one or more character-limited messages by replacing the URL with the shortened URL, and then cause transmission of the modified one or more character-limited messages to the user device. Next, the computing platform may receive, from the user device, a request to access the shortened URL, and redirect the user device to the detected URL corresponding to the shortened URL.
