Harden Windows OS to reduce the attack surface by disabling functionalities not required. Ransomware are known to spread via email as malicious attachments, that include DOC, XLS, VBS, JS, JSE, WSF. With our program you can unassociate these (uncommon) file types so when your employee opens a file named invoice.js, it will fail to open. You can mitigate Microsoft Office exploits by disabling Macros, OLE and ActiveX. You can disable Windows Script Host (wscript.exe) so JS, VBE, VBS, WSH scripts will fail to execute. We included also some smart Windows Firewall rules to block outbound connections of commonly hijacked programs so they cannot download remote files or send data anywhere.
