&gt; What reason for existence will they have then? EV certs?<p>I doubt that corporate users will move in any significant numbers to LE, even for basic DV certs.<p>Two reasons:<p>1. The certificate renewal process appears to be incompatible with most corporate change-control processes I&#x27;ve encountered: <i>nothing</i> may change on a production server unless an admin is given authorisation to change it.  A cron job that could take all customer-facing services offline is just crazy[0].<p>2. When something goes wrong with a cert issuance or renewal, corporate users ( want | need ) to be able to call a human to have them fix it, regardless of cost.  And even that cost is insignificant in context to revenue.<p>I&#x27;m sure LE will be popular with bloggers and hobby users.  Beyond that?<p>[0] yes, the admins could run the LE client manually in non-prod and move the certs over to production.  But that&#x27;s no easier than current cert renewals, and would have to occur every 60-90 days.
