🤖 Trust Analysis

After conducting a thorough safety and legitimacy analysis, csfirst.withgoogle.com receives a trust score of 62/100, 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 and HSTS (HTTP Strict Transport Security) enforcement preventing protocol downgrade attacks. 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, 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 csfirst.withgoogle.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.

csfirst.withgoogle.com Performance & Web Vitals Report

🤖 Performance Analysis

csfirst.withgoogle.com delivers its homepage in 21875ms (server response time), which is considered slow by industry standards. The total page weight is 1252 KB, and we detected 28 resource requests loading assets from 11 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 0 CSS files and 0 out of 2 JavaScript files are minified. Minifying the remaining 2 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 csfirst.withgoogle.com produces approximately 0.61g of CO₂, earning a carbon rating of F. The website's carbon footprint could be reduced by optimizing images, enabling compression, reducing third-party scripts, and leveraging caching. For reference, the average web page produces about 0.5g of CO₂ per page view. The page weight of 1252 KB is the primary factor in this calculation. Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for csfirst.withgoogle.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.

csfirst.withgoogle.com DNS Records, Email Authentication & Domain Registration

🤖 DNS Analysis

csfirst.withgoogle.com resolves to the IPv4 address 142.251.38.81 and also supports IPv6 (2a00:1450:4026:808::2011), demonstrating modern network infrastructure readiness. The domain has 1 A record(s) configured. Email for csfirst.withgoogle.com is handled by Google Workspace with 10 MX records configured: gmr-smtp-in.l.google.com, alt1.gmr-smtp-in.l.google.com, and aspmx.l.google.com and 7 more. Multiple MX records provide failover redundancy — if the primary mail server is unavailable, email will be routed to the next available server. SPF is not configured, meaning any server could potentially send emails pretending to be from this domain. This is a significant email security concern. DMARC is not configured, leaving the domain vulnerable to email spoofing and phishing attacks that impersonate this domain. 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 csfirst.withgoogle.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.
