aecom.com Trust Score & Safety Analysis
🤖 AI Summary
After conducting a thorough safety and legitimacy analysis, aecom.com receives a trust score of 72/100, 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, HSTS (HTTP Strict Transport Security) enforcement preventing protocol downgrade attacks, SPF (Sender Policy Framework) email authentication preventing email spoofing, DMARC email authentication with a reject policy — the strongest available setting, and DKIM (DomainKeys Identified Mail) providing cryptographic email verification.
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 aecom.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.

aecom.com Performance, Speed & Core Web Vitals
🤖 AI Summary
aecom.com delivers its homepage in 12068ms (server response time), which is considered slow by industry standards. The total page weight is 149 KB, and we detected 257 resource requests loading assets from 9 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: 3 out of 16 CSS files and 16 out of 31 JavaScript files are minified. Minifying the remaining 28 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.
The site is served through a Content Delivery Network (CDN), which caches static assets at edge servers around the world. This means visitors from different geographic regions receive content from the nearest edge server, significantly reducing latency. CDN usage is particularly important for websites with a global audience, as it can reduce page load times by 40-60% for distant visitors.
From an environmental perspective, each page view of aecom.com produces approximately 0.07g 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 149 KB is the primary factor in this calculation.
Core Web Vitals data from the Chrome User Experience Report (CrUX) is not available for aecom.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.

aecom.com DNS Records, Email Authentication & Domain Registration
🤖 AI Summary
aecom.com resolves to the IPv4 address 23.185.0.2 and also supports IPv6 (2620:12a:8001::2), demonstrating modern network infrastructure readiness. The domain has 1 A record(s) configured.
The domain name system is managed by 2 name servers: dns1.cscdns.net and dns2.cscdns.net. 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 aecom.com is handled by pphosted.com with 2 MX records configured: mxa-00219703.gslb.pphosted.com and mxb-00219703.gslb.pphosted.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 not enabled for aecom.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.
Our subdomain enumeration scan discovered 3 active subdomains for aecom.com: help.aecom.com, support.aecom.com, and www.aecom.com. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.

aecom.com SEO Analysis, Meta Tags & Open Graph
🤖 AI Summary
The title tag for aecom.com is good at 5 characters: "AECOM". The length is acceptable, though it may be slightly truncated in some search result displays.
No meta description is configured for aecom.com. This is a critical SEO oversight — without a meta description, Google will auto-generate a snippet from page content, which may not accurately represent the page or entice users to click. Adding a unique, compelling meta description of 120-155 characters is strongly recommended.
The canonical url is correctly set to https://aecom.com/, preventing duplicate content issues, the page language is declared as en-us, the meta robots directive is set to max-image-preview:large, and a favicon is configured.
Open Graph meta tags are configured with 3/4 recommended fields: OG title ("AECOM | AECOM..."), OG image (social sharing thumbnail), OG type (website). These tags control how the page appears when shared on Facebook, LinkedIn, and other social media platforms that support the Open Graph protocol.
A Twitter Card of type summary is configured, which controls how links appear when shared on Twitter/X. The "summary" type displays a large image preview, which typically generates higher engagement rates than the basic card type.
The site implements Schema.org structured data with the following types: ImageObject, Organization, SearchAction, WebPage, and WebSite. Structured data helps search engines understand the page content and can enable rich results (featured snippets, knowledge panels, star ratings) in Google search results, which can significantly increase click-through rates.
