This is a research-based decision resource. It contains no affiliate tracking, paid placement, numerical ranking, or claim of hands-on testing. Product features, prices, rules, and availability can change; verify current primary information before acting.
Compare content delivery networks by coverage, caching, security, operations, and economics. Verify evidence, complete cost, risks, and exit.
Start with the decision—not the feature list
A CDN can reduce distance and origin work, but cache rules, dynamic behavior, security, logging, invalidation, and outage design determine the result. Treat coverage, caching, and security as separate claims; then verify ownership of operations and economics.
A website choice also assigns responsibility for hosting, updates, accessibility, security, performance, backups, domains, integrations, and migration. The editing experience is only one part of long-term ownership.

| Decision area | What to verify | Why it matters |
|---|---|---|
| Coverage | Require current, plan-specific evidence for regions, networks, protocols, static and dynamic traffic, images, video, and routing. | Without this evidence, the decision can misstate coverage and transfer unplanned work, cost, or risk to the buyer. |
| Caching | Require current, plan-specific evidence for keys, headers, cookies, query strings, TTLs, invalidation, and stale behavior. | Without this evidence, the decision can misstate caching and transfer unplanned work, cost, or risk to the buyer. |
| Security | Require current, plan-specific evidence for TLS, origin shielding, DDoS controls, WAF, bot tools, access, and certificates. | Without this evidence, the decision can misstate security and transfer unplanned work, cost, or risk to the buyer. |
| Operations | Require current, plan-specific evidence for logs, analytics, configuration history, testing, incident response, and support. | Without this evidence, the decision can misstate operations and transfer unplanned work, cost, or risk to the buyer. |
| Economics | Require current, plan-specific evidence for requests, bandwidth, egress, rules, security products, logs, overages, and exit. | Without this evidence, the decision can misstate economics and transfer unplanned work, cost, or risk to the buyer. |
Who should consider it—and who should pause
Keep the option on the shortlist when
- Coverage is tied to a defined outcome and the team can document regions, networks, protocols, static and dynamic traffic, images, video, and routing.
- A representative scenario can demonstrate keys, headers, cookies, query strings, TTLs, invalidation, and stale behavior under the buyer’s actual constraints.
- Named owners have the authority and resources to manage logs, analytics, configuration history, testing, incident response, and support, requests, bandwidth, egress, rules, security products, logs, overages, and exit, maintenance, recovery, and an eventual exit.
Do not commit yet when
- Coverage remains a headline claim rather than evidence covering regions, networks, protocols, static and dynamic traffic, images, video, and routing.
- The recommendation assumes TLS, origin shielding, DDoS controls, WAF, bot tools, access, and certificates will work without confirming prerequisites, exceptions, or responsible parties.
- No written plan assigns ownership for logs, analytics, configuration history, testing, incident response, and support, requests, bandwidth, egress, rules, security products, logs, overages, and exit, failure recovery, or replacement.
A practical path from research to decision
Build a representative page and workflow in staging, then test accessibility, performance, forms, permissions, backup, update, rollback, export, redirects, and domain control before committing.
- Document the current baseline and required result for Coverage, including regions, networks, protocols, static and dynamic traffic, images, video, and routing.
- Ask every serious option to demonstrate keys, headers, cookies, query strings, TTLs, invalidation, and stale behavior with the same representative scenario and acceptance rule.
- Map prerequisites, inputs, dependencies, and responsible parties for TLS, origin shielding, DDoS controls, WAF, bot tools, access, and certificates before comparing price or convenience.
- Simulate a realistic exception involving logs, analytics, configuration history, testing, incident response, and support; record detection, decision authority, communication, recovery, and evidence retained.
- Model the complete first-year, renewal, maintenance, and failure cost associated with requests, bandwidth, egress, rules, security products, logs, overages, and exit, including staff and outside-provider time.
- Write a go/no-go record that identifies unresolved assumptions, the person accepting each residual risk, and the tested cancellation, transfer, or replacement path.
Cost, commitments, and exit
Compare the complete commitment, including coverage, caching, security, operations, economics, migration and exit. Record renewal, usage, outside-provider, implementation, maintenance, and exit assumptions separately from the advertised starting price.
A web capability is decision-ready only when it works with representative content, assistive interaction, required integrations, production constraints, rollback, and export.
Problems to prevent before commitment
- Coverage is reduced to a marketing label instead of checking regions, networks, protocols, static and dynamic traffic, images, video, and routing.
- Caching is inferred from a polished demonstration rather than tested against keys, headers, cookies, query strings, TTLs, invalidation, and stale behavior.
- Security moves forward without confirming TLS, origin shielding, DDoS controls, WAF, bot tools, access, and certificates and the dependencies behind it.
- Operations has no accountable owner for logs, analytics, configuration history, testing, incident response, and support.
- Economics and the exit decision are deferred until after commitment, even though they depend on requests, bandwidth, egress, rules, security products, logs, overages, and exit.
Questions to answer before committing
- For Coverage, what current evidence covers regions, networks, protocols, static and dynamic traffic, images, video, and routing?
- For Caching, what current evidence covers keys, headers, cookies, query strings, TTLs, invalidation, and stale behavior?
- For Security, what current evidence covers TLS, origin shielding, DDoS controls, WAF, bot tools, access, and certificates?
- For Operations, what current evidence covers logs, analytics, configuration history, testing, incident response, and support?
- For Economics, what current evidence covers requests, bandwidth, egress, rules, security products, logs, overages, and exit?
- Which unverified assumption could change the recommendation, who must resolve it, and what is the deadline before commitment?

Bottom line
Choose only when the evidence fits the real use case, responsibilities are assigned, complete cost is understood, and a tested recovery or exit path exists.
How we evaluated this page
We evaluated the decision using current public guidance from W3C Web Accessibility Initiative, WordPress.org Documentation, FTC: Hiring a Web Host and category-specific criteria for scope, evidence, implementation, ongoing responsibility, risk, and exit. We did not purchase, install, subscribe to, benchmark, or request sales or support service from a product provider.
