Blockade is a browser extension that brings antivirus-like capabilities to user web traffic by blocking malicious resources from being viewed or loaded inside Chrome or Firefox. The browser extension, developed by Brandon Dixon, can be configured to receive blocklists from multiple nodes. Security Without Borders maintains a node regularly updated with thousands of malicious websites, particularly those used in attacks targeting members of civil society.

How does it work?
The Blockade browser extension will regularly fetch an updated list of malicious websites from the nodes that you have configured in the options. Security Without Borders maintains a list of malicious websites that we observe through our own research as well as through automated collection techniques. We identify and block hundreds of suspicious and malicious domains every day.
I got a warning from Blockade, what do I do?
A Blockade warning will appear as a vivid red page in your browser alerting that you've visited a website marked as malicious (or that a website you visit has attempted to load a remote resource from a website marked as malicious). Don't panic, you should be fine.
If you have configured the extension with your own email address, we will receive a notification of this event and we would then be able to get back in contact with you.
If you believe that a website you visited was wrongfully blocked, please get in contact with us at
