GSB clean

WebRisk clean

Certificate valid until: 2026-12-05T23:59:59+00:00.

Email security: SPF On, DMARC quarantine.

Applies 4/6 security headers.

No mixed content detected.

Looking at operator information together with trust metrics helps you judge brand/merchant consistency and the likelihood of long‑term operation.

Checking payment page security (HTTPS enforcement, form target host consistency, script integrity) along with customer support and return policy gives a more accurate sense of real‑world trust.

In parallel, applying security headers, automated certificate renewal, email domain protection (DMARC/TLS‑RPT), and removing mixed content will improve overall reliability and delivery/search stability.

Explanation — risks and areas to improve

Without HSTS, downgrade and man‑in‑the‑middle attacks can weaken HTTPS enforcement. Enable HSTS and prepare for preload registration.

Without DNSSEC, trust relies solely on parent name servers and DNS tampering risks can be higher in some environments.

Without MTA‑STS, SMTP TLS enforcement is weaker.

Without TLS‑RPT, it is harder to collect TLS failure signals and operational insight.

Without security.txt, the vulnerability disclosure channel is unclear and response may be delayed.

Looking at operator information together with trust metrics helps you judge brand/merchant consistency and the likelihood of long‑term operation.

Threat insight

Mostly safe (risk 0/100)
  • Without HSTS, downgrade and man‑in‑the‑middle attacks can weaken HTTPS enforcement. Enable HSTS and prepare for preload registration.

The risk score of this site is calculated by combining browser security headers, SSL status, mixed content, email domain protection (SPF/DMARC), redirect/obfuscation patterns, and the results of Google Safe Browsing and WebRisk. There are currently few clear signs of malicious behavior, but insufficient security headers or email protection can increase the risk of phishing or man‑in‑the‑middle attacks. Before entering important information, re‑check the domain spelling and how you reached the site (ads, DMs, shortened URLs, etc.). Before entering payment or personal information, verify operator information (company/contact), HTTPS enforcement, DMARC/TLS‑RPT, and check for mixed content.

Deep scan (HTML / headers)

Mostly safe (deep 0/100)

Before entering payment or personal information, verify the site operator/contact, HTTPS enforcement (HSTS), and the presence of DMARC and TLS‑RPT.
