Dear ista customer,

As you may know, ista is dealing with a cyberattack. As a result, you cannot change your password for our web portals at the moment. Creating a new account is also not possible at the moment. For the reason that our web portals are not able yet to send e-mail messages. We are sorry for the inconvenience!

Once the problem has been resolved, we will report it on our website: www.ista.com/nl/updates

With your current login credentials you can use our portal, where you can view and compare the current consumption as you are used to..
