Edgecast (now Edgio) is an enterprise CDN with 300+ PoPs serving governments, media companies, and enterprises worldwide — but as a delivery platform it has no WCAG accessibility audit, no Core Web Vitals scoring, and no post-deployment front-end quality monitoring. PageGuard audits any Edgecast/Edgio-delivered website externally — free, no CDN access needed, results in 30 seconds.
ADA Title II Deadline: April 24, 2026
Enterprises, government agencies, educational institutions, and media companies using Edgecast/Edgio CDN face ADA Title II and Section 508 compliance requirements. Edgecast/Edgio delivers HTML pages and assets at enterprise scale — but cannot enforce that the HTML it serves implements correct alt text (WCAG 1.1.1), ARIA landmarks, keyboard navigation, or color contrast. An accessibility regression cached and served at Edgecast/Edgio's 300+ global PoPs is immediately delivered at massive scale with no Edgecast/Edgio alert. PageGuard monitors any CDN-delivered website for WCAG compliance without requiring CDN account access or configuration changes.
PageGuard vs Edgecast/Edgio — enterprise CDN and edge security vs deployed website quality monitoring
| Feature | PageGuard | Edgecast / Edgio |
|---|---|---|
| What is it? | External website health monitor — scans any deployed URL for performance, accessibility, SEO, and best practices | Edgecast (formerly Verizon Digital Media Services, now part of Edgio after Edgio's merger with Limelight Networks) is an enterprise CDN and edge platform founded in 2006 and acquired by Verizon in 2013; Edgecast built a global anycast CDN network serving major enterprises, media companies, and government agencies with web content acceleration, video streaming, large-file delivery, DDoS mitigation, and edge security; after Verizon sold Edgecast to College Parent Inc. in 2022 the company was renamed Yahoo and then merged with Limelight Networks to form Edgio in 2022; the combined Edgio platform operates 300+ PoPs in 80+ countries; as a CDN and edge delivery platform Edgecast/Edgio focuses on fast content delivery and security, not on auditing the accessibility or SEO quality of the content it delivers — it has no built-in WCAG compliance checking, Core Web Vitals auditing, or technical SEO analysis |
| Free tier | ✓ Yes — unlimited one-off scans, no signup required | No free tier — Edgecast/Edgio operates on enterprise contract pricing based on traffic volume and feature requirements; pricing is quote-based and requires direct sales engagement; designed for enterprises with significant CDN traffic volumes, not individual websites or small businesses; none of the CDN delivery tiers include WCAG accessibility auditing, Core Web Vitals measurement, or technical SEO analysis of delivered content |
| Accessibility audit (WCAG / ADA) | ✓ Yes — WCAG 2.1 AA scored 0–100 with specific issue list | No — Edgecast/Edgio is a CDN and edge delivery platform; it has no built-in WCAG compliance checking, accessibility scoring, or ADA compliance monitoring for the web pages it delivers; Edgecast/Edgio routes HTTP requests to edge PoPs, applies caching rules, applies edge security policies, and delivers responses — it does not parse, analyze, or validate the HTML content of those responses for missing alt text (WCAG 1.1.1), insufficient color contrast (WCAG 1.4.3), ARIA landmark structure (WCAG 1.3.1), keyboard navigability (WCAG 2.1.1), or any other WCAG 2.1 success criterion; Edgecast/Edgio can deliver accessible or inaccessible web pages with equal efficiency — accessibility quality is determined entirely by the origin server's HTML, not by the CDN layer |
| Technical SEO audit | ✓ Yes — meta tags, headings, canonical, structured data | No — Edgecast/Edgio provides no SEO audit of the web pages it delivers; Edgecast/Edgio can be configured to modify HTTP response headers, enforce HTTPS redirects, and apply edge-side URL rewriting — but these are infrastructure-level delivery configurations, not content-level SEO audits; Edgecast/Edgio does not analyze the meta title, meta description, heading hierarchy, canonical URL tag, structured data markup, or internal link quality of the HTML pages it delivers; Edgecast/Edgio's analytics provide traffic metrics, cache hit rates, bandwidth consumption, and security event data — not whether the delivered HTML pages have missing title tags or duplicate H1 elements that could harm search rankings |
| Performance audit (Core Web Vitals) | ✓ Yes — LCP, CLS, FCP scored 0–100 per scan | No — Edgecast/Edgio does not directly measure browser-side Core Web Vitals (LCP, CLS, FCP, INP) for pages it delivers; Edgecast/Edgio contributes to server-side performance through its global anycast CDN network, edge caching, and TLS optimization — but these CDN-side improvements do not measure the actual browser-experienced LCP, CLS, or FCP of the rendered page; Core Web Vitals are browser-side metrics that depend on rendering, layout stability, and interactivity — factors beyond the CDN delivery layer |
| Global CDN delivery and edge security | No — PageGuard is an external monitoring tool, not a CDN or content delivery infrastructure | ✓ Yes — this is the core value proposition of Edgecast/Edgio: enterprise CDN delivery with 300+ PoPs in 80+ countries, combining the Edgecast and Limelight networks after the 2022 merger; Edgecast/Edgio offers web content acceleration with anycast routing and edge caching, streaming delivery for OTT video and live events, large-file delivery for software and game distribution, enterprise-grade DDoS mitigation and WAF at the edge, TLS termination and certificate management, origin shield to protect backend servers, edge logic for HTTP request/response manipulation, and advanced analytics with real-time traffic and security visibility |
| Automated website monitoring | ✓ Yes — weekly or daily scans with email alerts on score drop | No — Edgecast/Edgio does not perform automated front-end quality monitoring of WCAG compliance, Core Web Vitals, or SEO quality for pages it delivers; Edgecast/Edgio's monitoring and alerting capabilities focus on CDN operational health such as origin error rates, cache hit ratios, DDoS attack alerts, and bandwidth trends — not HTML content quality, accessibility compliance, or SEO correctness; an accessibility regression introduced after a deployment and immediately cached at Edgecast/Edgio's 300+ global PoPs would be invisible to Edgecast/Edgio's monitoring infrastructure |
| AI-generated plain-English report | ✓ Yes — explains issues in non-technical language | No — Edgecast/Edgio provides no AI-generated health report or plain-English explanation of front-end accessibility, SEO, or Core Web Vitals issues for pages it delivers; Edgecast/Edgio's reporting covers CDN performance and security metrics — bytes transferred, cache performance, HTTP error rates, DDoS mitigation events — not content-level quality issues in the HTML being served to browsers |
| ADA Title II compliance monitoring | ✓ Yes — WCAG audit + alert on accessibility regression | No — Edgecast/Edgio does not audit or alert on WCAG compliance for pages it delivers; enterprises, government agencies, educational institutions, and media companies using Edgecast/Edgio's CDN face ADA Title II and Section 508 compliance requirements; Edgecast/Edgio delivers HTML pages and assets to users with high performance and reliability — but whether those pages implement correct alt text, keyboard navigation, ARIA roles, sufficient color contrast, or proper focus management is determined entirely by the origin server's content, not by the CDN delivery layer; an accessibility regression cached and served at Edgecast/Edgio's 300+ global PoPs is immediately delivered at enterprise scale with no Edgecast/Edgio alert or detection; ADA Title II deadlines apply with equal force regardless of which CDN delivers the non-compliant content |
| Works on any deployed platform | ✓ Yes — scans any URL on any hosting or platform | Edgecast/Edgio delivers content for its contracted enterprise customers; it does not scan or monitor the front-end quality of websites it does not serve; PageGuard audits any URL regardless of whether it is served through Edgecast/Edgio, Cloudflare, Akamai, Fastly, or any other CDN infrastructure |
| Independent external audit | ✓ Yes — third-party scan, shareable URL for clients/stakeholders | No — Edgecast/Edgio provides no built-in tool to generate a shareable external front-end health report for websites it delivers; Edgecast/Edgio's portal provides CDN analytics and security dashboards — internal operational tools, not client-shareable accessibility or SEO quality reports |
| Instant on-demand scan | ✓ Yes — results in 30 seconds, no code changes needed | No — no on-demand front-end health scan of websites delivered through Edgecast/Edgio; auditing an Edgecast/Edgio-delivered website for WCAG accessibility, Core Web Vitals, or SEO quality requires running third-party tools against the public URL; Edgecast/Edgio has no built-in concept of on-demand accessibility or SEO quality scanning of the content it serves at the edge |
| Multi-site dashboard | ✓ Yes — 1–50 sites depending on plan | Edgecast/Edgio can serve multiple properties under an enterprise account with property-level configuration, routing rules, and CDN analytics; there is no multi-website front-end health dashboard showing WCAG compliance, SEO quality, or Core Web Vitals for websites delivered through Edgecast/Edgio's CDN network |
| Pricing for health monitoring | ✓ Free + from $9/mo for automated monitoring | Front-end health monitoring not available — Edgecast/Edgio uses enterprise contract pricing based on traffic volume and feature set; no publicly listed pricing; custom quotes required; no WCAG or Core Web Vitals monitoring at any tier |

Yes — PageGuard scans any public URL regardless of the CDN infrastructure delivering it, including websites served through Edgecast (now Edgio). Paste the public URL of your Edgecast/Edgio-delivered website into PageGuard for a full health report covering WCAG 2.1 AA accessibility, Core Web Vitals performance, technical SEO quality, and best practices in about 30 seconds. No CDN portal access, Edgio account credentials, or configuration changes required.
No — Edgecast (now part of Edgio) is a CDN and edge delivery platform. It has no built-in WCAG compliance checking, accessibility scoring, or ADA compliance monitoring for the web pages it delivers. Edgecast/Edgio routes HTTP requests to edge PoPs and delivers cached or freshly fetched responses — it does not parse or validate the HTML content for missing alt text, ARIA landmark structure, keyboard navigability, or color contrast. Detecting WCAG violations on an Edgecast/Edgio-delivered website requires an external audit tool like PageGuard.
Yes — websites delivered through Edgecast/Edgio CDN face the same WCAG and ADA compliance requirements as websites on any other infrastructure. Edgecast/Edgio delivers HTML pages efficiently but performs no accessibility validation. Enterprises, government agencies, and educational institutions using Edgecast/Edgio face ADA Title II and Section 508 compliance requirements with an April 24, 2026 deadline. An accessibility regression cached and served at Edgecast/Edgio's 300+ global PoPs — missing alt text, broken keyboard navigation, insufficient color contrast — is immediately delivered at enterprise scale with no Edgecast/Edgio alert. PageGuard detects these issues by auditing the live rendered HTML of the public URL.
No — they serve completely different purposes. Edgecast/Edgio is a global enterprise CDN that delivers content fast with DDoS mitigation, WAF, and edge security across 300+ PoPs. PageGuard is an external quality monitoring tool that audits deployed web pages for WCAG accessibility compliance, Core Web Vitals performance, and technical SEO quality. Organizations using Edgecast/Edgio for CDN delivery should also use PageGuard to verify that the pages served through the CDN meet WCAG requirements — accessibility quality that CDN delivery infrastructure cannot enforce on the origin HTML content it serves.
