Where the score comes from

We look at six areas. Here's how zerossl.com did in each.
85
Security

Solid encryption with modern TLS and clickjacking protection. The security headers are decent but missing a few advanced protections like HSTS, which is worth noting for a security-focused service but not alarming.

90
Identity

Long-standing domain (over a decade) with clear legal entity disclosure. The company behind the site is publicly identifiable, which is strong for any online business.

80
Reputation

Clean blacklist status and moderate traffic indicate an established presence. No major trust signals like Trustpilot or extensive web archives, but nothing negative either.

85
Transparency

About page, contact info, and legal disclosure are all present. Lack of social media links is minor for this type of technical service; they communicate who they are well.

85
Compliance

Privacy policy and terms of service are published, plus a legal entity disclosure required by EU law. For a commercial site handling user accounts, this meets expectations.

80
Infrastructure

Fast, reliable hosting via Cloudflare with email authentication and multiple DNS servers. DNSSEC is not enabled, but that's a common gap and doesn't significantly hurt trust for most users.

ZeroSSL.com is a well-established provider of free and paid SSL certificates, a service that sits at the core of website security. For a business in this space, trust is everything, and the signals here are reassuring. The domain has been active since 2016, and the company behind it — ZeroSSL GmbH — is publicly listed with a legal disclosure page. That level of transparency is what you'd expect from a legitimate operator competing with the likes of Let's Encrypt or Comodo.

When it comes to safety, the site uses modern TLS encryption and basic browser protections. There's no history of malware or blacklisting, and Google Web Risk reports a clean bill of health. While the site's security headers aren't exhaustive, they're adequate for its function. Identity-wise, the combination of a long domain age and clear company info puts anxiety to rest.

If you're wondering whether zerossl.com reviews or a zerossl.com scam check is needed, the evidence points to a legitimate, well-run service. The main thing to watch with any certificate provider is whether they deliver on issuance and support — and ZeroSSL has been doing both for years. It's a safe bet for securing your website.
