APPLICATION SECURITY

Cloudflare WAF & DDoS Protection

Enterprise-grade application security delivered from Cloudflare's global Anycast network. Managed rulesets, bot detection, rate limiting — millions of threats blocked without impacting legitimate traffic.

THE CHALLENGE

Modern attacks outpace static defenses.

DDoS attacks growing in sophistication — volumetric, protocol and application-layer combined

Bot traffic consuming 40-60% of web requests, distorting analytics and scraping content

API endpoints exposed without proper authentication, rate limiting or schema validation

Legacy WAF rules generating false positives that block real customers

OUR APPROACH

Adaptive security at Cloudflare scale.

01

Managed WAF deployment

OWASP Core Ruleset, Cloudflare Managed Rules and custom rules — tuned for your application. We eliminate false positives through staged deployment and traffic analysis.

02

DDoS mitigation

Unmetered DDoS protection across L3/L4/L7. Cloudflare's 321 Tbps network absorbs attacks at the edge — your origin never sees malicious traffic.

03

Bot Management

ML-based bot detection with JavaScript challenges, managed challenge pages and Turnstile. Distinguish good bots from credential stuffers and scrapers.

04

Rate Limiting & API Shield

Per-endpoint rate limits, API schema validation, mTLS authentication. Protect your APIs from abuse without impacting legitimate integrations.

USE CASES

Security scenarios we handle.

DDoS under attack

Emergency onboarding for organizations under active DDoS attack. DNS cutover to Cloudflare within hours, immediate mitigation.

Bot mitigation

Stop credential stuffing, inventory hoarding, price scraping and content theft — while preserving SEO crawlers and partner integrations.

PCI DSS compliance

WAF rulesets aligned with PCI DSS requirements for e-commerce and payment processing applications.

Security analytics

Real-time threat dashboards, attack pattern analysis, monthly security reports with recommendations.

ARCHITECTURE

Multi-layer security architecture.

Cloudflare's security stack processes every HTTP request through multiple inspection layers — from DDoS mitigation at L3/L4 to WAF rule evaluation at L7 — before it reaches your origin server.

IMPLEMENTATION

Our WAF deployment methodology.

A risk-free approach that eliminates false positives before enforcing rules — ensuring zero impact on legitimate traffic.

01

Traffic Baselining

Onboard domain to Cloudflare in proxy mode. Analyze 1–2 weeks of traffic patterns: legitimate user agents, API consumers, bot profiles, geographic distribution.

1–2 weeks
02

Rule Deployment (Log Mode)

Deploy OWASP Core Rules, Cloudflare Managed Rules and custom rules in log-only mode. Monitor matches without blocking. Identify false positives.

1–2 weeks
03

Tuning & Enforcement

Whitelist legitimate patterns, tune sensitivity scores. Switch rules to block mode incrementally — starting with high-confidence categories (SQLi, XSS, RCE).

1 week
04

Ongoing Operations

Real-time monitoring dashboards, weekly threat reports, monthly security reviews. Rule updates for new CVEs. Incident response within SLA timeframes.

FAQ

Frequently asked questions.

How quickly can you onboard us if we are under DDoS attack?

Emergency onboarding can be completed within 2-4 hours. We perform a DNS cutover to route traffic through Cloudflare's network, configure baseline WAF rules and activate DDoS mitigation — all while keeping your application available.

Will the WAF block legitimate traffic?

We deploy WAF rules in log-only mode first, analyze traffic patterns for 1-2 weeks, then tune rules to eliminate false positives before switching to block mode. Ongoing monitoring ensures zero impact on real users.

Do you provide 24/7 security monitoring?

Yes. Our NOC team monitors WAF events, DDoS alerts and bot scores around the clock. We respond to incidents within SLA-guaranteed timeframes and provide monthly security review reports.
