HTTPS enforced with HSTS in Subscription management and billing
We measure this ourselves on their own site. It is the cheapest security control there is.
8 of 10 companies we measured here publish it, that is 80%. Last checked 2026-09-16.
80% here against 62% across every category we measure. Subscription management and billing sits above the overall share for this criterion.
This page counts companies, not product entries: a company with two products in this category is one company here and two rows below.

Published
HTTP redirects to HTTPS and the HSTS header is set.
No enforced HTTPS with HSTS found.
We reached at least one address for each of these vendors and none of them carried it. That is what we found at the addresses we checked, on the date we checked them, and not a statement about what the vendor has.
| Vendor | What we found |
|---|---|
| BillingPlatform | 2 addresses checked |
| Oak Software | 2 addresses checked |
Not measured
We could not look at these, or their robots.txt asks us not to. That says something about our measurement, not about them, and they are left out of the percentage above.
| Vendor | What we found |
|---|---|
| Subscription DNA | This vendor was not measured because our run stopped waiting for it. |
Found something we missed? Tell us. A correction moves that vendor into our next nightly run. That run reads the same fixed addresses we check for every vendor, not the address you send.
