No, unfortunately. There are firewalls that have some form of data control. However, this is a limited part of your data. A lot of data moves around your network securely or is not visible to smart firewalls. The best remedy for keeping these forms of cybercrime at bay is not in your network but in the security of endpoints, data, users, servers etc. Up-to-date endpoints, antivirus (or even better EDR), encryption, a good password policy, a solid rights structure on your data, MFA on all your external software and/or services do provide more security. The final benefit lies in your staff, who you can train in security awareness. Prevention can never be 100% guaranteed, but if things do go wrong, we will be there for you. We will help you to get back up and running quickly.
