Smart WAF blog — edge security, explained honestly
Engineering-depth writing on web application firewalls, DDoS defence, and data-sovereign edge security — no invented benchmarks, every claim traced to code that runs at the edge.
AI crawlers are eating your bandwidth — how to allow the good ones and block the rest
AI scrapers now make up a large share of automated traffic. Here is how Smart WAF tells a verified crawler from an impostor at the edge — cryptographic bot auth, not a spoofable user-agent string — and lets you decide who gets in.
Read more →How we measure WAF latency — and why we label every number
The incumbents call their added latency "virtually zero" with no number behind it. Here is exactly how Smart WAF measures the overhead its filtering adds — Server-Timing, percentile queries over real request logs, and a through-the-edge Lighthouse harness — and why every figure we publish is labelled staging-measured.
Read more →API security at the edge — protecting REST and GraphQL where the abuse actually lands
APIs are the biggest attack surface most teams under-protect. Here is how Smart WAF defends REST and GraphQL endpoints at the edge — signature rules, rate shaping, and behavioral scoring — without a brittle per-endpoint config sprawl.
Read more →What a managed WAF actually does — and what "managed" should mean
A managed web application firewall is more than a rule engine you rent. Here is what Smart WAF runs on your behalf: dual signature WAF engines on the OWASP ruleset, a graduated challenge ladder, and hands-on onboarding — no self-serve dead ends.
Read more →A European Cloudflare alternative — honest about the gaps
Looking for a Cloudflare alternative hosted in the EU? Here is where Smart WAF fits, where it deliberately does not compete, and why an honest feature map beats a badge wall for a security vendor.
Read more →Rate limiting that actually stops credential stuffing — not just a counter per IP
A naive per-IP rate limit does nothing against a botnet spread across thousands of addresses. Here is how Smart WAF stops credential stuffing and brute-force at the edge: distributed counters, behavioral scoring, and a graduated response.
Read more →WAF vs CDN security: what each actually protects
A CDN and a WAF are often sold together, but they solve different problems. Here is what a content delivery network protects, what a web application firewall protects, and why Smart WAF is the second one — not the first.
Read more →OWASP CRS explained: the rule categories behind the block
The OWASP Core Rule Set is the community ruleset that most serious WAFs stand on. Here is what CRS actually checks, how anomaly scoring works, and how Smart WAF runs it across two signature WAF engines.
Read more →Virtual patching — buying time at the edge when a zero-day drops on a Friday
A fresh CVE lands and the vendor patch is days away. Virtual patching at the edge blocks the exploit before it reaches your unpatched origin. Here is what Smart WAF can and cannot do to buy you that time honestly.
Read more →Taming WAF false positives — tuning OWASP rules without breaking your app
The reason teams turn their WAF off is false positives blocking real users. Here is how Smart WAF tunes the OWASP ruleset — anomaly scoring, per-site thresholds, and an audit trail — so you keep protection without the collateral damage.
Read more →The challenge ladder — proof-of-work, then CAPTCHA, then verified-bot auth
Blocking suspicious traffic outright punishes real users. Challenging it proportionately does not. Here is how Smart WAF escalates a doubtful client through proof-of-work, CAPTCHA, and cryptographic bot auth — each rung matched to the confidence.
Read more →GDPR-compliant edge logging — keeping the audit trail without leaking the personal data
A security edge sees every request, which means it sees personal data. Here is how Smart WAF keeps a defensible audit trail while staying GDPR-native: EU-only data residency, configurable retention, an immutable log, and the right to deletion.
Read more →Leaving a legacy enterprise WAF — a migration checklist that avoids the outage
Migrating off an incumbent WAF is where teams cause their own outage. Here is a practical checklist for moving to Smart WAF safely: detection-first cutover, DNS strategy, TLS continuity, and how to roll back without drama.
