Website Screenshots
Kiwi.com scores 66/100 and is flagged suspicious by the scanner, but the evidence does not point to malware or fraud. The site uses valid TLS 1.3 with a certificate issued by Certainly Intermediate R1, and major threat checks came back clean.
SSL Certificate & HTTPS Security
Kiwi.com is serving a valid SSL certificate over TLSv1.3, issued by Certainly Intermediate R1 (Certainly). HTTPS is enforced with HSTS enabled, which is a positive sign for transport security. The certificate expires in 13 days, so the site is currently protected, but the short remaining validity means the certificate should be renewed soon.
The scan also found that the site responds with HTTP 200 and resolves to the final URL https://www.kiwi.com/en/. That is normal behavior for a legitimate commercial site. The main security gap is not the certificate itself, but the absence of several hardening headers: X-Frame-Options, Referrer-Policy, Permissions-Policy, COEP, CORP, and X-XSS-Protection.
Threat Intelligence Results
The threat checks are clean across the board. Google Safe Browsing shows no issues, URLhaus is clean, and DNS blocklists from Spamhaus and SURBL also show no listings. That means the domain is not currently associated with known phishing, malware distribution, or spam infrastructure.
This is important because malicious travel-booking lookalikes are common. In this case, the scan found no evidence of threat infrastructure, and the domain reputation is marked trusted. The suspicious verdict comes from the overall scoring model, not from any active blacklist hit or malware finding.
Domain History & WHOIS Analysis
Kiwi.com is a known domain with a trusted reputation and a long-standing presence. The scanner identifies it as a legitimate travel booking platform, and the AI summary states the domain has been active for over 30 years with no known malicious history. The registrar is MarkMonitor, Inc., which is commonly used for brand protection by established companies.
The domain creation date is unknown in the scan data, so the exact registration age is not confirmed here. Even so, the combination of known brand status, reputable registrar, and consistent commercial infrastructure supports a legitimate business profile rather than a throwaway scam domain.
Is Kiwi.com Legitimate?
Yes � kiwi.com is a legitimate travel booking platform, and the scan data supports that conclusion. It has valid HTTPS, clean threat intelligence results, trusted domain reputation, and no signs of malicious infrastructure.
The only caution is that the site is not perfect from a security-hardening perspective: several HTTP security headers are missing, and the scanner still assigns a suspicious label with a 66/100 score. That does not make the site unsafe, but it does mean users should still verify bookings, prices, and refund terms carefully before paying.
