We performed a comprehensive analysis of thunderbird.net on 2026-06-28. The website returned an HTTP 403 status code with a server response time of 14671ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 5 KB, and the site is served behind a CDN (Content Delivery Network). Warning: The website does not have a valid SSL certificate. Visitors may see security warnings in their browser, and data transmitted to and from this website is not encrypted. The security headers analysis reveals a score of 80/100 (good). The following security headers are properly configured: Content-Security-Policy, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy. However, the site is missing Strict-Transport-Security (HSTS), which could expose the site and its users to cross-site scripting (XSS), clickjacking, and other web-based attacks. Our technology detection scan identified 1 technologies across 1 categories powering thunderbird.net. The detected stack includes Cloudflare. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, thunderbird.net receives an overall trust score of 75/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, thunderbird.net receives a trust score of 75/100, which places it in the "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, 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, and DNSSEC providing authenticated DNS responses. Areas of concern include: 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 thunderbird.net 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.

CDN: Cloudflare — accelerates content delivery by caching assets at edge locations worldwide for thunderbird.net.

thunderbird.net resolves to the IPv4 address 172.66.166.3 and also supports IPv6 (2606:4700:10::6814:1abb), demonstrating modern network infrastructure readiness. The domain has 2 A record(s) configured. The domain name system is managed by 2 name servers: kia.ns.cloudflare.com and nick.ns.cloudflare.com. Having 2 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 thunderbird.net is handled by Google Workspace with 5 MX records configured: aspmx.l.google.com, alt1.aspmx.l.google.com, and alt2.aspmx.l.google.com and 2 more. 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 thunderbird.net, 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. Our subdomain enumeration scan discovered 5 active subdomains for thunderbird.net: blog.thunderbird.net, docs.thunderbird.net, mail.thunderbird.net, support.thunderbird.net, and www.thunderbird.net. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.

The title tag for thunderbird.net is good at 16 characters: "Just a moment...". The length is acceptable, though it may be slightly truncated in some search result displays.
