Mitigate Cybersecurity Threats

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 ISO, IMG, 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 abused system processes such as powershell.exe, certutil.exe and curl.exe.
