Preventing Data Loss Using Enhanced Analysis of the URLs and URIs in Webpage Requests

A computing platform comprising:

• at least one processor;
• a communication interface communicatively coupled to the at least one processor;
• and
• memory storing computer-readable instructions that, when executed by the at least one processor, cause the computing platform to:
• transmit, by a user and to a proxy server, a request to access a webpage;
• determine, by the proxy server, whether:
• the webpage is included in a baseline associated with the user;
• or
• the webpage is not included in the baseline associated with the user;
• based on determining the webpage is not included in the baseline associated with the user, determine, by the proxy server and using an accessibility repository, whether:
• the webpage is accessible;
• or
• the webpage is inaccessible;
• based on determining the webpage is accessible, instruct an artificial intelligence model to analyze the webpage;
• parse, by the artificial intelligence model, a URL and a URI associated with the request;
• determine, by the artificial intelligence model, whether:
• the URI corresponds to source code associated with the webpage;
• or
• the URI fails to corresponds to the source code;
• based on determining that the URI fails to correspond to the source code, flag, by the artificial intelligence model, the webpage as malicious;
• transmit, by the artificial intelligence model and to the proxy server, instructions to deny the request to access the webpage;
• store, by the artificial intelligence model, the webpage in the accessibility repository;
• and
• transmit, by the proxy server and to the user, a notification indicating denial of the request to access the webpage.

One or more non-transitory computer-readable media storing instructions that, when executed by a computing platform comprising at least one processor, memory, and a communication interface, cause the computing platform to:

• transmit, by a user and to a proxy server, a request to access a webpage;
• determine, by the proxy server, whether:
• the webpage is included in a baseline associated with the user;
• or
• the webpage is not included in the baseline associated with the user;
• based on determining the webpage is not included in the baseline associated with the user, determine, by the proxy server and using an accessibility repository, whether:
• the webpage is accessible;
• or
• the webpage is inaccessible;
• based on determining the webpage is accessible, instruct an artificial intelligence model to analyze the webpage;
• parse, by the artificial intelligence model, a URL and a URI associated with the request;
• determine, by the artificial intelligence model, whether:
• the URI corresponds to source code associated with the webpage;
• or
• the URI fails to corresponds to the source code;
• based on determining that the URI fails to correspond to the source code, flag, by the artificial intelligence model, the webpage as malicious;
• transmit, by the artificial intelligence model and to the proxy server, instructions to deny the request to access the webpage;
• store, by the artificial intelligence model, the webpage in the accessibility repository;
• and
• transmit, by the proxy server and to the user, a notification indicating denial of the request to access the webpage.
