Yes you can prevents users from uploading confidential data using SafeSquid.
When you have confidential information in your organization and someone from internal users just leaked the information intentionally or unintentionally, then what will happen? Huge productivity loss.
There are various mediums for data leakage. Users can upload important document to internet, even though your content filtering software does not allow users to upload Microsoft Word and Microsoft XL files, users can act smart and creates an archive using those files and tries to upload achieved files. You cannot simply block archives in your organization because there are people who simply use archive to transfer log files of large sizes.
There are other users who simply take information out of Microsoft Word and Microsoft XL and simply send an Email to third party.
In modern era, these kind of data leaks become a challenge for organizations. Organizations are in a quest for content filtering software’s which can deeply inspect archive files and able to identify whether the archive or emails which contains certain keyword matches.
This challenge is also big for security experts because when there is an upload the post data formation is different for Gmail / Google Drive/ Media fire/ Drobox etc. The wide range of formations of post data made it difficult for security experts to derive concrete solution to these challenges.
But SafeSquid come up with Advanced DLP solution embedded into SafeSquid SWG, which analyzes post data, deeply inspect archives using file decomposition methods and able to identify whether archive or emails or social media posts contains certain keyword matches. Based on the match you can take effective actions like block upload if user is so and so or block if the destination website is so and so.
The Advanced DLP solution can managed from SafeSquid Self Service portal there you can create various keyword expression matches. SafeSquid SWG will download those keyword expressions and loads into memory. When an archive uploads or an email writes, SafeSquid SWG analyzes Post data and transmit it to the ClamAV daemon for Signatures verification. If the keyword expression matches ClamAV daemon responds with match. SafeSquid will take respective action based on match.
