Esek answers your phone calls and your messages on WhatsApp, Instagram and Messenger. Scams arrive by message too, so here is what is checked today, and what no check can promise.

Links in customer messages, in message buttons and in replies from the AI assistant are checked against Google Web Risk, Google's list of phishing, malware and unwanted software sites.

Files are opened on our servers first

Documents sent to you on WhatsApp, Instagram or Messenger are opened on our servers first, and every link inside them is checked the same way. This covers Word, Excel and PowerPoint files, PDFs and text files.

Scam images and documents from new senders

When someone you have never replied to sends an image or a document, an AI model looks for the signs of a scam:

A likely scam is blocked like a dangerous file. A possible scam shows a warning before you open it.

The model gets the image, or the start of the document's text. It does not get the file name, the caption, the sender's name or number, or the conversation. Files from people you have already replied to are not sent to it.

Blocking a sender

You can block a sender on WhatsApp right from the conversation. Meta allows this only within 24 hours of their last message.

On Instagram and Messenger, block the sender in Meta's own app. Meta gives other apps no way to report a sender, so report it in Meta's app as well.
