Common signs: bot traffic, attack attempts and site slowdowns. Usual causes: origin exposed and no WAF rules. What we do: set up Cloudflare WAF, rate limits and origin lockdown, then tune. What you get: protection at the edge with real users unaffected.
Our Cloudflare WAF setup puts your website and API behind Cloudflare's web application firewall, with rules tuned for your app, rate limits on sensitive paths, bot protection and origin lockdown. A Codersarts engineer sets it up, runs rules in log mode first, fixes false positives and then turns on blocking. Fixed price from $199 with 1-day delivery.

What Is the Cloudflare WAF?
Cloudflare's web application firewall inspects every request to your site before it reaches your server, and blocks attacks such as SQL injection, cross-site scripting, bad bots and request floods. It works with managed rule sets, your own custom rules and rate limiting, all running on Cloudflare's network.
Signs You Need a WAF
Your logs show constant login attempts or vulnerability scans
Bots scrape your content or create fake sign-ups
Your site slowed down or went offline during a traffic spike
Your server's IP address is public and reachable directly
A customer or insurer asked whether you use a WAF
Why Apps Need Edge Protection
Automated attacks
Bots scan every public site for known vulnerabilities and weak logins.
Exposed origin
Attackers go straight to your server's IP and skip any protection.
No rate limits
Unlimited requests make brute force, scraping and floods easy.
Default settings
Cloudflare is added for DNS, but security features are never configured.
Quick Checks You Can Try First
Make sure your DNS records are proxied (orange cloud) in Cloudflare.
Set SSL mode to Full (strict) with a valid certificate on your server.
Turn on Cloudflare's managed rules if your plan includes them.
Check whether your server's IP still answers requests directly.
If the problem remains, our engineers take it from there.
How We Set Up Your WAF
Review. We review your domain, hosting, traffic and sensitive paths.
Configure. We set up DNS, SSL, managed rules and custom rules.
Limit. We add rate limits on login, sign-up, search and APIs.
Protect bots. We add bot rules and Turnstile challenges on forms.
Lock the origin. We allow server traffic only from Cloudflare.
Tune. We run in log mode, fix false positives, then enable blocking.
What You Get
Cloudflare WAF configured for your app
Rate limits on sensitive paths
Bot protection on login and sign-up forms
Origin lockdown so the WAF can't be bypassed
A short runbook for attacks and rule changes
Example result (illustrative)
A booking site faced thousands of fake sign-ups a day and credential-stuffing on login. After setup, rate limits and Turnstile on sign-up cut fake accounts to near zero, and the origin stopped answering direct requests. No customer complaints after tuning.

Access to your Cloudflare account, or permission to add your domain
Access to your server or hosting firewall settings
A list of sensitive paths such as login and API
Any third-party services that call your app

Key Terms Explained
WAF: web application firewall, which filters malicious HTTP requests
Origin: your actual server behind Cloudflare
Rate limiting: capping how many requests a client can make in a time window
Turnstile: Cloudflare's privacy-friendly alternative to CAPTCHA
Common Mistakes We Avoid
Turning on blocking for all rules without testing
Leaving the origin server open to direct traffic
Blocking webhooks and API integrations by accident
Adding CAPTCHA to every page

Frequently Asked Questions
Is the Cloudflare free plan enough?
It includes basic DDoS protection and some managed rules. Paid plans add fuller rule sets and advanced rate limiting, which most business apps benefit from.
Will the WAF block real users?
Not if it's tuned. We run rules in log mode first and fix false positives before blocking.
Do you need to change our code?
Usually not. Setup happens in Cloudflare and your server firewall.
We're under attack now. Can you help?
Yes. Contact us and choose emergency setup. It can usually be done the same day.
Stop Attacks Before They Reach Your Server
Bots and scanners hit every public app. Share your domain and a Codersarts engineer will put protection at the edge, tuned for your users.
