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.
Cookies without Secure / HttpOnly / SameSite can be vulnerable to theft or session fixation attacks.

- SSL certificate expiring soon
- 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.

User scenarios
If you make a payment on this site
No strong malicious signs were found, but online payments always carry some risk. Double-check the amount, payee and refund policy before you pay.
If you log in or enter personal data
No clear malicious patterns were found, but treat passwords and 2FA codes as highly sensitive. Avoid reusing passwords across sites. Missing cookie security attributes or cross-domain POST forms can make sessions easier to steal or misuse. After logging in, watch for unusual account or billing activity.
