VTScada Version 11.3 supports OpenID Connect, which allows VTScada Anywhere clients to integrate with third-party authentication servers. This allows a single sign-in for multiple systems and two-factor authentication. VTScada also supports IPv6, which allows almost unlimited addressing for cell modems and devices using public IPs. It uses Twilio, a third-party Web-based communications platform, as an alternative to modem hardware for voice telephony (but it still supports modems), which is important for systems running on virtual machines in server farms. The IEC driver supports time stamping and report by exception and allows communication with a variety of European devices.
