WAF that's actually tuned for your application

Cloudflare WAF applies rules globally across millions of sites — effective, but with default rules that generate false positives for specific application behaviors (custom checkout flows, search forms, file uploads). ZenoCloud Managed WAF runs a 14-day detection phase analyzing your specific application's traffic, identifies legitimate patterns that default rules would block, and builds a tuned rule set. We also monitor block logs continuously — something Cloudflare WAF doesn't do without a paid Security Operations subscription.

During the 14-day detection mode phase, all WAF decisions are logged but not enforced. We review the block log daily and identify false positives before going live. After enforcement begins, we monitor the block log and can whitelist legitimate traffic within hours of a false positive being reported. Our goal is zero impact on legitimate users.

Yes. For applications running behind AWS ALB, CloudFront, or API Gateway, we deploy and manage AWS WAF with AWS Managed Rule Groups. We tune rate limiting, custom rules, and Bot Control configuration specific to your application. AWS WAF pricing is per rule group and request volume — we scope this during onboarding.

WAF is a compensating control, not a code fix. It can block exploit attempts against known vulnerability classes (SQLi, XSS, path traversal), but it cannot fix insecure authentication logic, broken access control, or business logic flaws in your application. WAF buys time — the correct fix is always patching the code. We flag discovered vulnerabilities for your dev team with every monthly report.

Initial deployment is typically 24–48 hours. Detection mode runs for 14 days. Full enforcement begins at day 15, or sooner if the false positive analysis is clean. For complex multi-application environments, allow 3–4 weeks for full deployment and tuning.

PCI DSS Requirement 6.4 mandates web application protection — either a WAF or a code review process for all custom-developed applications. A managed WAF with documented rule sets and monthly review typically satisfies this requirement. Our monthly WAF reports provide the audit evidence required by QSA assessors.
