AWS WAF & Shield Support
AWS WAF & Shield support, troubleshooting and optimization.
AWS WAF filters malicious traffic, but poorly tuned rules block customers while attackers get through.
Common WAF & Shield problems we fix
The AWS WAF and Shield issues our engineers see most often, and how we resolve them.
WAF blocking legitimate users (false positives)
Managed rule groups can match valid requests. We put rules in count mode, review sampled requests, and exclude or scope rules precisely.
Bot traffic and scraping
We use rate-based rules, Bot Control and CAPTCHA challenges to limit abusive traffic.
SQL injection and cross-site scripting protection
We enable the core rule set and custom rules, and fix the application vulnerabilities behind them.
DDoS protection
Shield Standard is automatic. For critical apps we design layered defense with CloudFront, rate limiting and Shield Advanced where justified.
WAF logging and cost
Logging to S3 or CloudWatch and rule capacity units drive cost. We tune logging and rules.
