New Features

Vendor Support

  • Premium Support for ABB RTU 540/560

Tenable.io Integration

  • Added integration capabilities to Tenable.io. Integration setup is done with Tenable Support assistance and requires a Tenable.io Access Key, and Secret Key.

Detection of Ripple20 exploit attempts

  • Added an Intrusion Detection rule group which will detect successful identification attempts or exploits of Ripple20 affected assets over the network.


  • API Key - API improved to align with the standard Rest API spec. Starting 3.6.33, the API uses the 'X-APIKey' header instead of 'Authorization'

    The new header is: 'X-APIKeys: key= <API_KEY>'

    For example:

    curl -v -k -H 'X-APIKeys: key=Mbvf2sXdROWBrB99MBXwXN-LqYrWVxPEyos1IJk9e9aNPLOlWalkHkAfsS4=' https://IP/v1/status
