idealo.com

We performed a comprehensive analysis of idealo.com on 2026-06-29. The website returned an HTTP 200 status code with a server response time of 62437ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 189 KB. The website uses a secure HTTPS connection with a valid SSL certificate issued by Amazon (DV type). The connection is encrypted using TLS 1.3 with the TLS_AES_128_GCM_SHA256 cipher suite and sha256WithRSAEncryption signature algorithm. The certificate covers 1 domain(s) (Subject Alternative Names) and expires on 2026-10-09, which is 102 days from now. The security headers analysis reveals a score of 50/100 (moderate). The following security headers are properly configured: Strict-Transport-Security (HSTS), X-Frame-Options, and X-Content-Type-Options. However, the site is missing Content-Security-Policy, Referrer-Policy, and Permissions-Policy, which could expose the site and its users to cross-site scripting (XSS), clickjacking, and other web-based attacks. Our technology detection scan identified 4 technologies across 4 categories powering idealo.com. The detected stack includes React, Webpack, Google Tag Manager, and jQuery 51. The UI is built with React. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, idealo.com receives an overall trust score of 81/100, classified as "Very Likely Safe".

After conducting a thorough safety and legitimacy analysis, idealo.com receives a trust score of 81/100, which places it in the "Very Likely Safe" category. This score is calculated by evaluating multiple factors including SSL certificate validity, domain registration history, email authentication protocols, security header configuration, and blacklist status across major threat intelligence databases. The analysis identified several positive trust signals: a valid HTTPS connection protecting data in transit, HSTS (HTTP Strict Transport Security) enforcement preventing protocol downgrade attacks, a valid SSL certificate issued by Amazon with 102 days until expiration, SPF (Sender Policy Framework) email authentication preventing email spoofing, DMARC email authentication with a reject policy — the strongest available setting, DKIM (DomainKeys Identified Mail) providing cryptographic email verification, DNSSEC providing authenticated DNS responses, and a well-established domain registered for over 26.1 years, indicating long-term commitment and legitimacy. Areas of concern include: the absence of a Content-Security-Policy header, which leaves the site more vulnerable to cross-site scripting (XSS) attacks, missing Referrer-Policy, potentially leaking URL information to third parties, and the domain's WHOIS information is hidden behind a privacy service, making it harder to verify the owner's identity. While these issues don't necessarily indicate malicious intent, they represent areas where the website's security posture could be improved. We checked idealo.com against 8 major blacklist databases including Google Safe Browsing, Phishtank, Urlhaus, Openphish, Dnsfilter, Spamhaus Dbl, Surbl, and Virustotal. The domain passed all 8 checks with a clean status, meaning it has not been flagged for phishing, malware distribution, spam, or other malicious activities by any of the tested threat intelligence providers. The domain is registered through Gandi SAS based in DE, with a registration date of 2000-06-08 and expiration date of 2027-06-08.

idealo.com delivers its homepage in 62437ms (server response time), which is considered slow by industry standards. The total page weight is 189 KB, and we detected 278 resource requests loading assets from 14 third-party domains. A high number of third-party domains can significantly impact page load time due to additional DNS lookups and TLS handshakes required for each domain. The website uses Gzip compression for text-based assets, achieving an estimated 60.0% reduction in transfer size. This reduces bandwidth usage and improves page load times, especially for visitors on slower connections. Asset minification status: 0 out of 2 CSS files and 1 out of 36 JavaScript files are minified. Minifying the remaining 37 unminified file(s) could further reduce page weight by 10-30% for those assets. Minification is a best practice that reduces download sizes without affecting functionality. From an environmental perspective, each page view of idealo.com produces approximately 0.09g of CO₂, earning a carbon rating of A. This places the website among the cleanest on the web, demonstrating efficient use of server resources and optimized content delivery. For reference, the average web page produces about 0.5g of CO₂ per page view. The page weight of 189 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for idealo.com. This typically means the site doesn't have enough real-world Chrome user traffic to generate statistically significant field data, or the domain is not included in the CrUX dataset. Core Web Vitals (LCP, INP, CLS) are important Google ranking factors that measure real user experience.

idealo.com resolves to the IPv4 address 45.89.128.96 and also supports IPv6 (2a0b:a200:0:102:e6c6:fbcc:ad:1d4e), demonstrating modern network infrastructure readiness. The domain has 3 A record(s) configured. The domain name system is managed by 4 name servers: ns-1218.awsdns-24.org, ns-1589.awsdns-06.co.uk, ns-246.awsdns-30.com, and ns-680.awsdns-21.net. Having 4 name servers provides good redundancy — if one fails, the others can continue serving DNS queries. The choice of name servers often indicates the DNS hosting provider or CDN service being used. Email for idealo.com is handled by Microsoft 365 with 1 MX records configured: idealo-com.mail.protection.outlook.com. Multiple MX records provide failover redundancy — if the primary mail server is unavailable, email will be routed to the next available server. SPF (Sender Policy Framework) is configured, which specifies which mail servers are authorized to send email on behalf of this domain. This helps prevent email spoofing and improves email deliverability. DMARC (Domain-based Message Authentication, Reporting and Conformance) is configured with a reject policy — the strongest setting, instructing receiving servers to reject unauthorized emails entirely. DKIM (DomainKeys Identified Mail) is configured, adding a cryptographic signature to outgoing emails that receiving servers can verify to confirm the email hasn't been tampered with in transit. DNSSEC is enabled for idealo.com, providing an additional layer of security by cryptographically signing DNS records. This prevents DNS cache poisoning and man-in-the-middle attacks that could redirect visitors to malicious websites. The domain is registered through Gandi SAS (DE). It was first registered on 2000-06-08 and is set to expire on 2027-06-08, making it 26.1 years old. Our subdomain enumeration scan discovered 4 active subdomains for idealo.com: api.idealo.com, cdn.idealo.com, support.idealo.com, and www.idealo.com. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.
