thinkwave.com

We performed a comprehensive analysis of thinkwave.com on 2026-07-01. The website returned an HTTP 200 status code with a server response time of 9108ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 60 KB. The website uses a secure HTTPS connection with a valid SSL certificate issued by Google Trust Services (DV type). The connection is encrypted using TLS 1.3 with the TLS_AES_256_GCM_SHA384 cipher suite and sha256WithRSAEncryption signature algorithm. The certificate covers 1 domain(s) (Subject Alternative Names) and expires on 2026-09-22, which is 83 days from now. The security headers analysis reveals a score of 45/100 (below average). The following security headers are properly configured: X-Frame-Options, X-Content-Type-Options, and Referrer-Policy. However, the site is missing Content-Security-Policy, Strict-Transport-Security (HSTS), 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 thinkwave.com. The detected stack includes Vite, Google Analytics 4, StackPath, and Font Awesome. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, thinkwave.com receives an overall trust score of 71/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, thinkwave.com receives a trust score of 71/100, 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, a valid SSL certificate issued by Google Trust Services with 83 days until expiration, SPF (Sender Policy Framework) email authentication preventing email spoofing, and DMARC email authentication with a none policy. Areas of concern include: the absence of a Content-Security-Policy header, which leaves the site more vulnerable to cross-site scripting (XSS) attacks, the domain's WHOIS information is hidden behind a privacy service, making it harder to verify the owner's identity, and DNSSEC is not enabled, leaving DNS queries vulnerable to spoofing attacks. While these issues don't necessarily indicate malicious intent, they represent areas where the website's security posture could be improved. We checked thinkwave.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.

Our technology detection engine scanned thinkwave.com and identified 4 distinct technologies across 4 categories. This analysis is performed by examining HTTP response headers, HTML source code patterns, JavaScript library fingerprints, CSS framework signatures, and DNS records. Build Tool: Vite — bundles and optimizes the JavaScript and CSS assets for thinkwave.com. Analytics: Google Analytics 4 — tracks visitor behavior and provides traffic insights for thinkwave.com. CDN: StackPath — accelerates content delivery by caching assets at edge locations worldwide for thinkwave.com. Icon Set: Font Awesome — provides additional functionality for thinkwave.com. We also extracted the following tracking identifiers: Google Analytics 4 Measurement ID G-3CV0PM7NJY. These IDs can be used to identify other websites operated by the same organization.

thinkwave.com delivers its homepage in 9108ms (server response time), which is considered slow by industry standards. The total page weight is 60 KB, and we detected 127 resource requests loading assets from 4 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 1 CSS files and 0 out of 2 JavaScript files are minified. Minifying the remaining 3 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 thinkwave.com produces approximately 0.03g 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 60 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for thinkwave.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.

thinkwave.com resolves to the IPv4 address 216.239.36.21 and also supports IPv6 (2001:4860:4802:36::15), demonstrating modern network infrastructure readiness. The domain has 4 A record(s) configured. The domain name system is managed by 4 name servers: ns-1270.awsdns-30.org, ns-1820.awsdns-35.co.uk, ns-407.awsdns-50.com, and ns-530.awsdns-02.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 thinkwave.com is handled by yahoodns.net with 2 MX records configured: mx-biz.mail.am0.yahoodns.net and mx-biz.mail.am0.yahoodns.net. 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 none policy — a monitoring-only setting that doesn't enforce any action on unauthorized emails. DKIM was not detected. Without DKIM, recipients cannot cryptographically verify that emails claiming to be from this domain are authentic. DNSSEC is not enabled for thinkwave.com. While not critical for most websites, DNSSEC adds an important security layer by ensuring DNS responses haven't been tampered with during transit. Enabling DNSSEC is recommended for domains handling sensitive data or financial transactions.

The homepage of thinkwave.com contains 2,338 words of visible text content. This is a substantial amount of content that provides good opportunities for search engine indexing. The page is structured with 7 H2 headings, 3 H3 headings, 25 H4 headings, 4 H5, and 0 H6 headings. The page includes 43 images. 5 images (12%) are missing alt text attributes, which is a significant concern for both accessibility and SEO. Screen readers rely on alt text to describe images to visually impaired users, and search engines use alt text to understand image content. Only 88% of images have proper alt text — we recommend adding descriptive alt attributes to all images. The link structure consists of 48 internal links pointing to other pages on the same domain and 17 external links pointing to third-party websites. There are 2 external JavaScript files, 1 CSS stylesheets, and 0 iframes on the page. The site implements the following web standards and features: robots.txt (controls search engine crawling behavior), Schema.org structured data (AggregateRating, ImageObject, LocalBusiness, Organization, PostalAddress, and SoftwareApplication), and Progressive Web App (PWA) manifest (enabling app-like installation). Notable missing features: XML Sitemap. Adding these could improve search engine discoverability and rich result eligibility. The website has social media presence across 2 platforms: Facebook (@ThinkWave) and Twitter (@ThinkWave). An active social media presence is a positive trust indicator and helps build brand awareness and customer engagement.
