You host a WordPress site on a European provider. Security wants Cloudflare "for WAF and CDN in one click." Product prefers Bunny CDN "because per-GB billing is readable." Both camps are right on their criterion — and wrong if they decide without mapping traffic.
Cloudflare is not just a CDN: it is DNS, TLS, DDoS, WAF, Workers, sometimes email routing. A specialist CDN (Bunny, KeyCDN, Gcore, Fastly depending on segment) focuses on delivering bytes fast with explicit cache rules. The useful comparison pits all-in-one integration against fine control and predictable pricing.
Two edge-layer philosophies
| Dimension | Cloudflare (generalist) | Specialist CDN |
|---|---|---|
| DNS | Often centralized at CF | Stays at host or registrar |
| Security | Built-in WAF, bot fight, rate limits | Varies; often combined elsewhere |
| Cache | Plan-based rules, advanced Workers | Pull/push zones, granular TTL |
| Billing | Feature-tier plans | Often per GB / request, clear |
| Dependency | Strong with orange proxy + CF DNS | Removable layer in front of origin |
| Ideal fit | Web site + security + unified DNS | Media, SaaS assets, multi-origins |
Choosing Cloudflare to "be protected" without reading WAF rules is like installing a firewall nobody knows the exceptions for.
When Cloudflare genuinely simplifies life
Small team, limited ops. One domain, auto cert, static cache, basic DDoS: Free or Pro covers a lot without extra servers.
Classic web attack surface. Public forms, exposed WordPress, need for rate limiting and OWASP-style rules without Akamai budget.
Workers and edge compute. Light logic (A/B tests, geo redirects, edge auth) without dedicated infra.
Limits show up when:
- Video traffic or huge files blow up cost or cache rules
- You need instant purge on thousands of objects with documented SLA (Fastly, some enterprise tiers)
- Compliance requires not routing all traffic through a US entity (Cloudflare is American — assess DPA and scope)
- WAF blocks legitimate clients (API false positives, webhooks)
When a specialist CDN wins
Heavy, predictable assets. Product images, PDFs, static front builds: Bunny or KeyCDN in front of S3 or object storage, billed per GB, without unused security bundle.
Multi-origin or multi-brand. Several domains, distinct origins, different cache rules per path — specialists often expose clear purge APIs and pull zones.
Security already elsewhere. On-prem WAF or host firewall, DNS at a European registrar: adding Cloudflare full proxy creates a second console and sometimes TLS conflicts.
Controlled egress. Compare outbound cost from your cloud (OVH, Scaleway, AWS) to the CDN vs to visitors. A bad pick sometimes doubles network bill.
Common migration mistakes
- Orange cloud without testing checkout — session cookies, real IP for origin rate limits, Stripe webhooks.
- Forgetting purge — front deploy without invalidation; visitors on broken old JS.
- Duplicated TLS — expired origin cert because "Cloudflare handles everything"; misconfigured Full (strict).
- Equating CDN with GDPR compliance — edge cache may store personalized responses; verify what is cacheable.
The peak: integrated security has a hidden price
All-in-one marketing skips the fact that the most aggressive WAF is not always safest for revenue: a checkout false positive costs more than a blocked injection attempt.
Decide and move forward without blind spots
- Map traffic types: dynamic HTML, API, media, webhooks.
- List security needs (WAF, DDoS, geo-block) vs pure performance.
- Test staging with and without proxy: cart, admin, partner APIs.
- Compare 12-month cost including egress and paid add-ons.

Frequently asked questions
Can Cloudflare replace a dedicated media CDN?
For HTML and typical assets, often yes. For streaming, large volume, or very specific rules, a specialist may fit better and sometimes cost less.
What is the risk of Cloudflare orange-cloud proxying?
Strong dependency, opaque WAF rules, global impact on outage or aggressive captcha. Keep direct origin access for debugging.
Is a specialist CDN without WAF dangerous?
Not automatically if security is handled elsewhere. Avoid two contradictory WAFs without documentation.
How do I compare real cost?
Add requests, bandwidth, edge options, support, and origin egress. Free covers simple cases; at volume, per-GB specialists can be more predictable.
Before choosing, ask: if I leave this edge provider in six months, how many pieces do I move? The answer separates integrated comfort from fine control.
