Charcoal is a cloud hosted Squid proxy URL Redirector, with an API driven helper. It is developed by us and is released under GPLv3 and AGPL.
It is best suited for environments where one has to manage multiple proxy servers at distributed locations. In such a scenario, managing blocklists and rules on each proxy server becomes an administrative nightmare.
Charcoal provides a way to manage blocklists and rules from a single portal. It already includes 70+ categories of domain blocklists, with facility to let you create your own custom lists.
Malware filtering on Web Traffic is achieved by enabling SSL Inspection and scanning with ClamAV and abuse.ch AV signatures.
Our domain blocklists are updated from various reputable sources across the world to block traffic to harmful destinations.
