The tool is deprecated and there is another open source tool that can be used instead. Here is the message on the repo;
WARNING: Don't use this piece of software anymore as the underlying web service will stop working at the end of January 2021. Instead, use the Open-Source CLI tool that does the same locally, or use the Symfony CLI tool.
We need to create a symbolic link to the new tool so that the people using security check will not get fail messages. This should be also stated on the README.
