Is thunderesp.com safe?

The scan of thunderesp.com on 20 Aug 2026 reached no verdict either way (score 6). Too little was captured to judge it, which is an unknown rather than a pass.

How was thunderesp.com checked?

A static pass resolved DNS, captured TLS and headers and followed the redirect chain, and where the standard tier allows, a headless browser rendered the page and recorded every request. Egress is SSRF-locked. Signatures that matched only page text are weighted far below one that matched a served file, because a page documenting malware matches the same rules.
