Symantec has recently discontinued their $20 per year Digital ID service that I used to encrypt PDFs for a small team. Is there a similarly priced Adobe-approved alternative?

I have been encrypting PDFs for a small group of users for nearly a decade using VeriSign/Symantec digital IDs.

Symantec has recently discontinued their $20 per year Digital ID service: https://www.symantec.com/products/information-protection/digital-ids-secure-email

Is there a similarly priced Adobe-approved alternative?

The size of my team does not warrant an enterprise solution.

Thanks.
