synthesys.io

We performed a comprehensive analysis of synthesys.io on 2026-06-28. The website returned an HTTP 200 status code with a server response time of 6066ms. The page is served over HTTP/2 protocol with Gzip compression enabled, achieving approximately 60.0% size reduction. The total page weight is 443 KB. 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: Strict-Transport-Security (HSTS), X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and Permissions-Policy. However, the site is missing Content-Security-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 6 technologies across 6 categories powering synthesys.io. The detected stack includes Next.js media, React, Google Tag Manager, Shop Pay, HubSpot, and Vercel. The site uses Next.js as its primary framework (version media). The UI is built with React. Based on our comprehensive analysis of domain age, SSL configuration, email authentication, security headers, and blacklist status, synthesys.io receives an overall trust score of 75/100, classified as "Likely Safe".

After conducting a thorough safety and legitimacy analysis, synthesys.io 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, HSTS (HTTP Strict Transport Security) enforcement preventing protocol downgrade attacks, SPF (Sender Policy Framework) email authentication preventing email spoofing, DMARC email authentication with a quarantine policy, 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, 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 synthesys.io 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 synthesys.io and identified 6 distinct technologies across 6 categories. This analysis is performed by examining HTTP response headers, HTML source code patterns, JavaScript library fingerprints, CSS framework signatures, and DNS records. Framework: Next.js (version media) — provides the application framework and routing for synthesys.io. UI Library: React — handles the user interface rendering and component management for synthesys.io. Tag Manager: Google Tag Manager — manages marketing and analytics tags without code changes for synthesys.io. Payments: Shop Pay — processes payment transactions for synthesys.io. Marketing: HubSpot — provides marketing automation capabilities for synthesys.io. Hosting: Vercel — provides the server infrastructure for synthesys.io. We also extracted the following tracking identifiers: Google Tag Manager container GTM-5QGF5KB. These IDs can be used to identify other websites operated by the same organization.

synthesys.io resolves to the IPv4 address 216.150.1.1, but does not support IPv6. IPv6 adoption is increasingly important as IPv4 address space becomes exhausted, and some ISPs and regions are transitioning to IPv6-only connectivity. The domain has 1 A record(s) configured. The domain name system is managed by 2 name servers: ns.liquidweb.com and ns1.liquidweb.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 synthesys.io is handled by synthesys.io with 1 MX records configured: mail.synthesys.io. 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 quarantine policy — a moderate setting, directing unauthorized emails to spam/junk folders. 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 synthesys.io. 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 25 active subdomains for synthesys.io: admin.synthesys.io, api.synthesys.io, app.synthesys.io, apps.synthesys.io, blog.synthesys.io, cdn.synthesys.io, community.synthesys.io, and dev.synthesys.io. Plus 17 additional subdomains. Active subdomains can reveal the organization's infrastructure, including development environments, API endpoints, and third-party service integrations.

The title tag for synthesys.io is well-optimized at 46 characters: "AI Video Agent for Marketing Teams | Synthesys". The length falls within the ideal range for Google search results, ensuring the full title is displayed without truncation. The meta description is 134 characters (well-optimized): "Create AI video ads, UGC & commercials in minutes. Trusted by Coca-Cola & Yahoo. 10X faster, 90%+ cheaper than tradition...". Google typically displays up to 155-160 characters of the meta description in search results. A compelling meta description with a clear call-to-action can significantly improve click-through rates from search results. The canonical url is correctly set to https://synthesys.io/, preventing duplicate content issues, the page language is declared as en, and a favicon is configured. Open Graph meta tags are configured with 4/4 recommended fields: OG title ("AI Video Agent for Marketing Teams | Synthesys..."), OG description, 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_large_image is configured, which controls how links appear when shared on Twitter/X. The "summary_large_image" 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: AggregateOffer, AggregateRating, Answer, ContactPoint, FAQPage, ImageObject, Organization, Person, PostalAddress, Question, Rating, Review, SoftwareApplication, SpeakableSpecification, 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.
