TLDRvia the TL;DR App

Slack + MetaCert = the safest messaging platform to share web links — whether you are a company concerned about insider threats, or an open community concerned about phishing attacks. Both are real threats as cyberattacks migrate from email to messaging.

MetaCert released a new killer feature today. I’d go as far as to say that “MetaCert for Slack” should win just about every infosec award that’s available. This is an engineering feat that will literally save the world for many — by helping them not lose their entire life’s savings while encouraging them to invest more money in more Token launches and ICO.

This only possible because MetaCert has enterprise-grade security infrastructure on the backend end with the world’s most advanced threat intelligence system. It’s not a simple bot by any means of the imagination. It might look that way because it takes about 7 seconds to install. Trust me, it’s not. The guts of the platform alone cost over $1m to build over a two year period. Think of MetaCert as “Stripe for Security” in the sense that all of our products are powered by a single API with just seven lines of code.

It’s that API that will return the classification of a URL after checking over 3,000 shortening services, finding the destination site and then checking that against 10 billion URIs — all in under 190ms.

Auto delete DMs with phishing links

After you install MetaCert inside your Slack, it will automatically protect your channels. But, you must ask users to “activate” the MetaCert bot to protect their DMs. This is a two-click job so will take them less than 5 seconds to do. I recommend you do this by sending regular requests in your main channel.

As soon as a user activates the bot, MetaCert will automatically deleted DMs that contain known phishing links — before they even know they had a message.

Auto delete DMs that contain dodgy keywords

We added a new feature today that will reduce phishing inside Slack, by up to 99% — provided users activate the bot and as our app champion, you add the right keywords. You can add as many keywords or phrases as you like.

The video below shows you how to setup the filter and how it works inside a Slack.

Disable DMs completely

You can also completely disable DMs for everyone except for your core team too. Here’s a post that explains how to do that.
