I suggest you share your snippet as code from here:

b
p
strong

Thank you Paul. Not sure how to use this. What I tried to insert are normal formatting tags I think: /b /strong /p

Can you provide a proper snippet of the json file?  Just showing the html tags isn't helpful at all.   For example:

{
"ad_box": {
"html": "<div class=\"ad_box\"><img class=\"banner\" src=\"some_ad.png\" alt=\"\" \/>
<h3>"Hot" Items <\/h3> <br \/> <ul id=\"items\" \/><\/div>",
"item_id": 1234,
"click_action":"/logAction?id=1234&type=click&info=blah",
"icon":"http://my.images.com/icons/icon.png"
}
}

Then it will be easier for someone to help you.

Thank you again! Sure, here's a snippet of the json file. (I have highlighted the tags in yellow.)

ok - it would have been more helpful if you just copy pasted the code itself rather than an image so I could show you how this works with your example.  Anyway... I retyped one like this this:

{
    "breach_summary": "<p>some text.</p><p><b>Some more text:</b><br/><ul><li>item 1</li><li>item 2</li></ul></p>",
    "breach_cause": "<p>some text.</p><p><b>Some more text:</b><br/><ul><li>item 1</li><li>item 2</li></ul></p>",
    "breach_detection": "<p>some text.</p><p><b>Some more text:</b><br/><ul><li>item 1</li><li>item 2</li></ul></p>"
}  

I then set up the json filetype with this option:

Then I see this:

Thanks a lot! I had tried this already and it did work but the whole file is divided just like in your screenshot so I had hoped there would be a more comfortable solution... If not, I suppose it will be ok for the translator.  

There are also many other non translatable elements like these ones. Can I also protect these?

Like this?

Just check this option:

You have two choices at the moment:

1. use the plain text processor and manually create all your rules:
   
   
2. or process the placeholders afterwards using something like the Trados Data Protection Suite from the appstore.
