    Clear instructions

    We run this weekly now and the report lands in my inbox without me remembering to ask. The seal has been useful on our checkout page. Renewal reminder arrived well before expiry, which I appreciated.

    Some back and forth

    The blacklist check alone was worth it, since that is what our host complains about. It flagged an outdated plugin before it became a problem. The instructions could be clearer about the intermediate certificate.

    A few hiccups

    Set the scan against our main site and had a usable report the same day. The report separates what is urgent from what can wait, which helps. Took longer than the estimate on the product page, though.

    Smooth from start to finish

    The findings were specific enough that our developer could act on them directly. Setup was one DNS record and nothing else. Support answered on the first try, at an hour I did not expect anyone to be awake.

Finish the job

  • Let an engineer install it

    Pick your server at checkout and one of our engineers installs the certificate, checks the chain and confirms the padlock. No test runs on your production box.

    Free tools to read a certificate, generate or decode a CSR, match a key to a certificate and confirm the chain your server is actually serving.

  • Not sure which one to buy?

    Answer three questions about how many domains you need to cover and whether your company name has to appear in the certificate, and the finder narrows it down. Or just ask an engineer.
