Every request to your website passes a checkpoint at the network edge. SQL injection, XSS, hostile bots, brute-force floods — identified and dropped there, so your site only ever meets clean traffic.
The WAF doesn't run on your website — it stands in front of it, at the network edge.
Visitors, crawlers, scanners, attackers — everyone arrives together
Signatures, patterns, rates and reputation checked in milliseconds
Real visitors continue to your site; attacks are dropped at the door
The attacks below hit every website on the internet, every day — including yours. This is what meets them.
Attempts to smuggle database commands through your forms and URLs — the classic route to stolen data — are recognized by pattern and blocked before they reach a query.
Injected scripts that hijack your visitors' browsers — to steal sessions or deface pages — are filtered out of requests at the edge.
Scrapers, credential-stuffers and vulnerability scanners are told apart from legitimate crawlers by behavior and reputation — good bots pass, bad bots don't.
Brute-force login storms and request floods hit a ceiling per source. Real users never notice; scripts hammering wp-login.php very much do.
Our rulesets track the OWASP Top 10 — the industry's reference list of web application risks — and are updated as new techniques appear. When a popular CMS vulnerability is disclosed, edge rules often block it before your site is even patched.
Volumetric floods meant to knock your site offline are absorbed and dispersed at the network edge — paired with autoscaling, the two layers hold the door together.
A firewall that needs a specialist isn't protection — it's a job opening. Ours ships running.
Security plugins inspect attacks after they've already reached your site — consuming your CPU, touching your PHP, sometimes exploiting the very plugin meant to stop them. An edge WAF drops hostile requests before they cross your threshold. Your site stays fast because it stays out of the fight.
A WAF inspects every HTTP request before it reaches your website and blocks the ones that look like attacks — SQL injection, cross-site scripting, malicious bots, brute-force attempts. Think of it as a security checkpoint standing in front of your site, not software running on it.
No. It's active on every VACLIC site, with rules kept current as new threats appear. There's nothing to install, license or tune.
Rules are tuned infrastructure-wide against false positives, and legitimate traffic — including good bots like search engine crawlers — passes freely. If a specific feature of your application ever trips a rule, support adjusts it for your site.
No — it blocks the bulk of automated attacks and buys you time when vulnerabilities are disclosed, but patched software remains essential. That's why the infrastructure pairs it with automatic updates, daily malware scanning and backups. The full security stack →
The firewall is already part of every VACLIC plan — along with scanning, isolation and backups. Protection starts with the first request.
