What can PARX do for you?

5-Point Action Plan:

  1. Identification:
    We will first analyse your instance to identify whether your are affected by the change and define the necessary actions that have to be taken.
  2. Actions:
    You address the actions that were identified in step 1 and if necessary test them in the sandbox. Optionally, we can do this for you on the basis of an individual offer.
  3. Live test:
    Together with you, we temporarily disable TLS 1.0 on the live instance and check the system in order to recognize any components which might have remained undetected in step 1.
  4. Corrections:
    You address any issues identified in step 3.
  5. Go live:
    We permanently disable TLS 1.0 in your instance.

May we help you to adjust your Salesforce instance to TLS 1.1 and higher? Please contact PARX as soon as possible to plan the next steps.
