What is Barracuda WAF?
A web application firewall is the cybersecurity control that stands between an application and everyone on the internet who has time. It does not repair the code — it buys the time in which the code can be repaired, and that distinction decides what may reasonably be expected of it.

FAQ
Does WAF replace secure coding? No. WAF is a defense layer, not a code fix. Best practice: secure coding + WAF + pentests. WAF offers “virtual patching” when code can’t be quickly fixed.
Does nFlo deploy Barracuda WAF? Yes. We design WAF architecture, deploy and tune rules. We also offer managed WAF services with 24/7 SOC.
