Does oantagonista.com publish the usual trust pages?

None of about, contact, privacy or terms could be found at their usual addresses.
That is common for small or single-purpose sites, and it is also what a disposable
site looks like, so it is worth noting rather than concluding from.

These were checked at conventional paths only, so a site using different URLs may
publish them elsewhere.

Where is oantagonista.com hosted?

The first address resolves to infrastructure in Toronto, Canada.

The network is operated by Cloudflare, Inc. (AS13335 Cloudflare, Inc.).

Hosting location describes where the responding server sits, not where the business is. A CDN will report its nearest edge rather than the origin.

What is oantagonista.com running on?

oantagonista.com exposes 3 identifiable technologies: Cloudflare, Google Analytics, Google Tag Manager.

Cloudflare sits in front of the origin, so the server header, IP addresses and response timing describe the edge rather than the machine actually running the site.

Visitor tracking is present (Google Analytics and Google Tag Manager), so this homepage is not cookie-free.

  • Cloudflare
  • Google Analytics
  • Google Tag Manager

How does the homepage respond?

The server answered with HTTP 200 over
HTTPS.

At 332ms to first byte this response is unremarkable for a homepage measured from a single European location.

The HTML weighs 334KB, which is ordinary for a homepage.

The HTML is compressed with gzip.

Server header cloudflare
Compression gzip
Page size 342,416 bytes
Declared language pt-BR
Mobile viewport declared

What does the homepage say about itself?

The title is only 13 characters, which is short enough that it probably is not describing the page so much as naming it.

A meta description of 99 characters is present.

2 of 86 images carry no alt attribute, which leaves them unreadable to screen readers and uninterpretable to image search.

Is oantagonista.com served over a valid certificate?

The HTTPS certificate is issued by Google Trust Services and is
valid until 2026-12-24, which is 80 days from the date of this check. It covers
2 hostnames.

  • oantagonista.com
  • *.oantagonista.com

The certificate has 80 days left to run.

It covers 2 hostnames, so it was issued for this site specifically.

Which security headers does it set?

None of the 6 headers checked are set. That is the default state of most servers rather than evidence of a problem, but it means the browser is given no instructions it could otherwise act on.

Without HSTS, a browser that has never visited before will try HTTP first, which is the window a network attacker needs.

With no Content Security Policy, any script that reaches the page — including one injected through a compromised third-party dependency — runs with full access to it.

Header Set Value
HSTS no —
Content Security Policy no —
X-Content-Type-Options no —
X-Frame-Options no —
