If you've come across gtssldv-ocsp.geotrust.com, it's easy to assume it's a legitimate part of the GeoTrust certificate system. But the reality is that this specific subdomain is broken and should not be trusted. The SSL certificate doesn't match the domain, meaning any attempt to connect is insecure. The site itself returns a 404 error, so it's essentially dead. While GeoTrust itself is a respected certificate authority, this endpoint appears to be an abandoned or misconfigured OCSP responder. There's no evidence of a scam, but the technical failures make it dangerous to rely on. If you see this URL in a configuration or error message, it's best to ignore or replace it with a working OCSP endpoint. For a technical service like this, a valid certificate and a reachable server are basic requirements, and both are missing here.
No — gtssldv-ocsp.geotrust.com doesn't look safe
In plain English
This site is not safe to use. The SSL certificate is invalid and the page returns a 404 error, meaning it's either broken or hijacked. Even though it's a subdomain of GeoTrust, a trusted brand, the endpoint itself is completely unreliable and should not be visited or relied upon for any purpose.

Where the score comes from
The SSL certificate is invalid and mismatched for this domain, meaning any connection is insecure and likely intercepted. The site is also unreachable, returning a 404 error, which makes it completely unusable.
This is a subdomain of the well-known GeoTrust brand, but the specific endpoint appears abandoned or misconfigured. The lack of domain registration details is normal for a subdomain, so no strong signals either way.
The domain has a 13-year archive history and is not on any blacklists, which suggests it was once legitimate. However, it has no current traffic rank and is effectively dead.
As a technical backend endpoint, missing contact info, about page, or social media is expected. This is not a consumer-facing site, so the lack of transparency is not a concern.
No legal pages are present, but that's normal for a non-commercial technical service. There are no obligations to provide privacy policies or terms for this kind of URL.
The site is hosted on Akamai, a reputable provider, but it returns a 404 and has no valid SSL configuration. The DNS resolves but the service itself is broken, which is a major red flag for any intended function.
