Pick Cloudflare WAF if your platform is multi-cloud, sits in front of more than just AWS, or if you want bundled DDoS, bot management, and CDN in one product without per-request billing. Pick AWS WAF if your traffic only touches ALB, CloudFront, API Gateway, or AppSync, your organisation has a no-third-party-vendor policy, or your compliance scope mandates AWS-native controls. Most production booking and e-commerce platforms end up on Cloudflare; most internal AWS-only workloads end up on AWS WAF. Pricing rarely decides it.
This is the comparison post that the rest of the internet does not write, because most of those posts are sponsored or single-vendor. The pricing and feature differences are real, but they are not the only thing that should drive the decision.
The honest verdict in one paragraph
Cloudflare WAF is a complete edge security product: WAF, Layer 7 DDoS, bot management, rate limiting, and global CDN bundled into one flat-rate plan. AWS WAF is a focused WAF that integrates tightly with AWS edge and load balancing services and bills per-request. If your application is on AWS and stays on AWS, AWS WAF is operationally simpler. If your application sits behind multiple origins, or you want bot management and DDoS as part of the same product, Cloudflare wins. Anyone telling you one is universally “better” is selling something.
Pricing: the real numbers
Cloudflare WAF. Starts at $25 per month on the Pro plan. Business plan ($200/month) adds advanced rate limiting and Super Bot Fight Mode. Enterprise is custom. Egress data is included. DDoS protection is included at every tier. There are no per-request charges for WAF inspection. The full feature breakdown is on the Cloudflare WAF product page.
AWS WAF. Web ACL: $5 per month. Each rule: $1 per month. Request inspection: $0.60 per million requests for the first 1,500 WCUs (web ACL capacity units). Body inspection above default size: $0.30 per million. Managed Bot Control: additional $10 per month plus $1 per million requests. Account Takeover Prevention: additional $10 per month plus $1 per million logins. AWS Shield Advanced (for Layer 3 and 4 DDoS protection above the free Shield Standard): $3,000 per month minimum commitment, 1-year term. The current rates are on the AWS WAF pricing page.
For a site doing 100 million requests per month with 20 rules and Bot Control enabled, AWS WAF runs roughly $5 + $20 + $60 + $10 + $100 = ~$195 per month before any Shield Advanced or fraud-control add-ons. The same site on Cloudflare Business is $200 per month flat, with bot management included. Pricing is close enough that it is not the deciding factor.
The pricing gap widens at high request volumes (Cloudflare flat, AWS scales with requests) and at low request volumes (AWS cheaper for low-traffic sites with simple rule sets).
Is AWS WAF cheaper than Cloudflare WAF?
Sometimes. For a low-traffic site with five managed rules, no bot control, and no fraud prevention, AWS WAF can run under $20 per month while Cloudflare’s nearest equivalent is $25. For any site large enough to need bot management or doing more than 50 million requests per month, Cloudflare’s flat rate usually wins on predictability and often on absolute cost.
The bigger pricing question is what each product includes. Cloudflare bundles DDoS protection and bot management. AWS bills them separately as Shield Advanced and Bot Control. By the time an AWS WAF deployment matches Cloudflare’s default feature set, the total monthly bill is higher, and the predictability is lower.
Where Cloudflare WAF wins
Bundled feature set. WAF, DDoS protection, bot management, rate limiting, CDN, and DNS all in one product. One dashboard, one bill, one team to learn.
Multi-cloud and hybrid origins. Cloudflare sits in front of any origin: AWS, Azure, GCP, on-premise, multi-region. It does not care where your application runs.
Operator experience. The Cloudflare dashboard is faster to navigate than the AWS WAF console. Rule iteration is faster. The expression language is more readable than AWS WAF statements. False positive triage in Security Events takes minutes instead of hours.
Bot management. Super Bot Fight Mode and Cloudflare Bot Management are widely considered better than AWS Bot Control for general web traffic. Cloudflare sees more of the internet, which means better bot fingerprint coverage. The case study on our Saudi mobility platform Cloudflare deployment shows scraper traffic dropping from 38% of incoming requests to under 3% after tuning Super Bot Fight Mode.
Global edge. Cloudflare has more cities in its network than AWS has edge locations, and the gap is wider in the Middle East. For a Saudi or GCC business, Cloudflare typically delivers lower latency than CloudFront. See our writeup on Cloudflare for Saudi Arabia for the regional infrastructure detail.
When AWS WAF is the right call
This is the section every other comparison post skips. AWS WAF wins in specific scenarios:
You are fully AWS-native and staying that way. ALB, CloudFront, API Gateway, AppSync. The integration is tight, the IAM model is the one your team already operates, and there is no extra vendor in the loop. CloudFormation and Terraform support is mature.
Your compliance scope mandates AWS-native services. Some government, financial services, and healthcare engagements require that all in-scope security controls run inside the AWS account boundary, with logs flowing to AWS-native destinations and access controlled by IAM. AWS WAF meets that. Cloudflare, as a separate vendor, does not.
You already operate AWS Shield Advanced. If you are paying for Shield Advanced (typically for DDoS protection on AWS-native infrastructure), AWS WAF integrates with it directly. Adding Cloudflare on top is duplication.
Your traffic shape is bursty and low-volume. AWS WAF’s per-request pricing can be cheaper than Cloudflare’s flat tier when traffic is low or sporadic and you do not need the bundled features.
You need extremely tight integration with AWS GuardDuty, Security Hub, or AWS WAF logs to S3. AWS WAF feeds the AWS security data lake natively. Cloudflare requires Logpush configuration to get logs into S3.
Your internal APIs only need to be reachable from inside the VPC. A WAF at the AWS edge attached to an internal ALB is the right model. Cloudflare is for public-facing traffic, not internal-only.
These are the honest scenarios. Outside them, Cloudflare is usually the better default.
Can I use Cloudflare WAF in front of AWS infrastructure?
Yes, and many production stacks do exactly this. The architecture: Cloudflare sits at the edge as the proxied DNS provider, terminates TLS, applies WAF and bot management, and forwards traffic to your AWS origins (ALB, API Gateway, EC2, ECS). You lock down the AWS-side security groups to accept traffic only from Cloudflare’s published IP ranges. This is a standard pattern.
The reason it works well: Cloudflare’s edge is wider than AWS CloudFront’s, so global users hit Cloudflare first and get faster TLS termination. AWS still does the application work. You get the best of both products. The trade-off is two vendors instead of one and slightly more complex routing.
Operator experience: the underrated decision driver
Most people compare WAFs on features and pricing. The real difference shows up in how fast your team can:
Triage a false positive. Cloudflare: open Security Events, filter by the affected URL, find the rule, click “Add exception”, done in 5 minutes. AWS WAF: navigate the console, find the rule group, write a Scope-Down statement, redeploy via Terraform or console, wait for propagation. Easily 30 minutes for the same outcome.
Write a custom rule. Cloudflare expression language reads like English: (http.request.uri.path contains "/admin") and not (ip.src in {1.2.3.0/24}). AWS WAF statements are JSON-style nested objects that take longer to read and write.
Roll back a bad rule. Cloudflare: disable in dashboard, done. AWS WAF: detach from Web ACL via Terraform/CloudFormation, redeploy, wait for propagation.
Read logs during an incident. Cloudflare Security Events is real-time and filterable. AWS WAF logs to S3 or Kinesis Firehose, which means you query them via Athena or a SIEM, which is slower under pressure.
None of these are dealbreakers. They compound over a year of operational work.
Migration: what moving between them actually costs
AWS WAF to Cloudflare. Cloudflare becomes the authoritative DNS, you re-write your rules in Cloudflare’s expression language (most translate directly), you lock AWS security groups to Cloudflare IPs, and you flip DNS. Time: one to two weeks if your rule set is modest, four to six weeks for a complex set.
Cloudflare to AWS WAF. Move the origin behind ALB or CloudFront, attach a Web ACL, translate Cloudflare expressions to AWS WAF statements (the verbose JSON model takes more lines), drop DNS proxy, accept that you lose Layer 7 DDoS unless you add Shield Advanced. Time: similar to the reverse, but you also need to plan for the feature gap.
If you already have one and it works, there is no compelling reason to migrate just for cost. Migrate because your architecture changed (added clouds, lost AWS scope), or because the operator experience is slowing your team down.
Common mistakes to avoid
Picking a WAF on pricing alone. Pricing is close. Pick on architecture fit, vendor strategy, and operator experience.
Assuming Cloudflare and AWS WAF are interchangeable. They have different default behaviour. Cloudflare blocks more by default; AWS WAF is permissive by default. A rule that works in one needs reverification in the other.
Running both at once “for defence in depth”. Two WAFs in series create two sources of false positives, two sets of logs to read during incidents, and almost no real security gain. Pick one, run it well.
Forgetting AWS Shield Standard is not enough. AWS Shield Standard ships free with every AWS account and covers basic L3/L4 DDoS. It does not cover Layer 7 application-layer attacks. If you want L7 DDoS on AWS WAF, you need Shield Advanced at $3,000/month minimum.
When to talk to us
If you are deciding between the two, or migrating in either direction, the decision is rarely just about WAF features. It involves your CDN choice, your DDoS posture, your bot management strategy, and your origin firewall rules. Our Cloudflare managed services cover deployment, tuning, and operation. Our AWS managed services cover the AWS-native side including AWS WAF setup with Shield Advanced integration. For broader edge and origin security strategy, see our cybersecurity services.
For reference on what a real Cloudflare deployment for a high-pressure booking platform looks like, see our Saudi mobility platform case study. The same controls translate directly to AWS WAF, with the trade-offs covered above.
