Is the B12 website safe?

Is the B12 website safe? Yes. B12 is a legitimate website builder company, and every site it publishes ships with HTTPS and TLS encryption enabled by default, per B12's own documentation. That covers the site it builds for you too: visitors get an encrypted connection from launch, with no certificate setup on your end. The company itself checks out as real. Its Trustpilot page held 212 customer reviews when we pulled the search results, it has been covered by TechRadar and other trade press, and independent reviews of its builder go back to at least 2020. If you landed here worried about the vitamin, that is a different B12; this one is b12.io, the AI website builder.

Safe and worth it are separate questions, though. B12's pricing starts at $49 a month and its done-for-you tiers reach $399 a month as of mid-2026, and the complaints reviewers report are about cost and flexibility, not security. Nothing in the sources we read suggests your data or your visitors are at risk on a B12 site. Plenty suggests you should look hard at the invoice.

So treat safety as settled and put your diligence where it pays: the downsides of B12 as reviewers report them, and our B12 review from a competitor, because yes, we sell against them and say so up front.
