Why put a web application firewall in front of your application

Automated traffic reaches an application within hours of going live, and almost none of it comes from a real browser. Our web application firewall checks that at the network edge — same principle as Cloudflare, without the dependency. A global service in front of your application can fail, be made to stop by a foreign decision, or be attacked over something that has nothing to do with you. Ours runs inside the infrastructure already hosting you.

Why put a web application firewall in front of your application

A web application exposed on the Internet doesn't need to be noticed to be visited. Within hours of going live, it starts receiving automated traffic: scanners hunting for a known flaw, scripts replaying stolen credential lists, bots harvesting content, tools probing for an unprotected admin path. That traffic is constant, cheap to run, and indifferent to your size.

Most of it has one thing in common: none of it comes from a real browser. That's the angle we chose to work on.

The usual answer is to hand that filtering over to a large global network — Cloudflare first among them, protecting roughly 20% of the web on its own. It works, and it is also one more dependency. A dependency isn't judged on how good it is, but on what it makes you risk when it gives way. And it can give way in three different ways.

It can fail. One internal failure at Cloudflare was enough to leave thousands of sites unreachable for several hours. Sites in perfect working order, unreachable because the service sitting in front of them had stopped answering.

It can be made to stop. A provider incorporated under US law remains subject to that law, whatever country its servers run in — that is the principle behind the CLOUD Act. A decision that isn't aimed at you can still determine access to your data, or the continuity of your service.

It can be attacked. A service concentrating a sizeable share of global traffic is, by construction, a prime target, and everyone behind it inherits its threat profile. An attack that was never aimed at you can take you down along with all the others.

Since May 2026, we've offered an alternative for the applications we host. The principle is the same: before your application is served, a web application firewall checks at the network edge that the request comes from a real browser rather than a robot, through an invisible challenge. The difference is where it runs. The filtering happens inside the infrastructure already hosting your application — no global intermediary between you and your visitors, no foreign jurisdiction over the service, no shared target you have no control over. There's no extra provider to depend on: if your hosting answers, your filtering answers.

Filtering automated traffic upstream doesn't make your application more robust. It means it stops spending its time answering requests that were never meant for it.

Where to start

This service will speak to you if any of these sound familiar:

  • Your logs are saturated with requests that go nowhere, and you've stopped reading them.
  • You've seen login attempts on accounts that don't exist, in bursts, from addresses you don't recognise.
  • Your content or your prices are being scraped, and you have no way of telling those requests apart from real visits.
  • You already sit behind a global filtering service, and you've started listing what you'd lose the day it stops answering.
  • Your business has sovereignty or continuity requirements, and a provider under foreign jurisdiction in front of your application is a problem in itself.
  • You'd like this kind of protection, but you have neither the time to set it up nor the wish to maintain it.

We can put a web application firewall in front of the applications we host for you, run it over time, and support the integration if your application needs one.

The first step costs nothing: book a slot and we'll go through your setup together.
