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.
Missing key security headers leaves the site vulnerable to clickjacking, MIME sniffing, and data leakage.
Without DNSSEC, trust relies solely on parent name servers and DNS tampering risks can be higher in some environments.
If DMARC is absent or set to p=none, protection against sender spoofing is weak. Consider quarantine/reject policies.
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.

Essentials
Threat insight
- Without HSTS, downgrade and man‑in‑the‑middle attacks can weaken HTTPS enforcement. Enable HSTS and prepare for preload registration.
- Missing key security headers leaves the site vulnerable to clickjacking, MIME sniffing, and data leakage.
- If DMARC is absent or set to p=none, protection against sender spoofing is weak. Consider quarantine/reject policies.
- Suspicious JavaScript patterns detected
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)
- Suspicious JavaScript obfuscation patterns have been observed.
If unexpected popups, wallet connection requests, or download prompts appear, cancel once and re‑check via official announcements or community channels.
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. Missing or weak DMARC lets attackers send spoofed payment emails. Type the domain manually instead of clicking links in unexpected messages.
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.
