Cloudflare is very good at what it was built for.

It absorbs traffic at massive scale, takes the hit during attacks, and filters out the most obvious abuse before it ever reaches your server. For a lot of websites, that alone is already enough.

But there is a type of traffic Cloudflare intentionally does not try to fully solve.

Traffic that looks normal.

Requests that don’t flood anything, don’t break rules, and don’t trigger alarms. One request here, one request there. Rotating IPs. Reasonable paths. Clean user agents. From the outside, everything looks fine.

From the application’s point of view, it often isn’t.

This is the gap IPIntel was built for.

Intent is not the same as traffic

Most modern malicious activity no longer behaves like an attack.

It blends in. Quietly. Intentionally.

Cloudflare sees a technically valid request. There is nothing obvious to block yet. And that is not a failure. It is a design choice.

Judging intent is not something infrastructure alone can do.

Where IPIntel fits

IPIntel doesn’t try to replace Cloudflare, and it doesn’t compete with it.

It exists to answer a different question: have we seen this kind of behavior before, and what usually happens after it?

That question cannot be answered by looking at a single request in isolation. It requires memory and context that extend beyond one website.

IPIntel brings that context to the edge.

The Cloudflare integration is implemented as a simple Worker and is documented here: https://ipintel.ai/cloudflare-worker

The IPIntel Cloudflare Worker

The Worker is intentionally simple.

It is a single JavaScript file. No SDKs. No dependencies. No changes to your application.

When a request arrives at the Cloudflare edge, the Worker evaluates the real visitor IP using IPIntel.ai and makes a decision before the request ever reaches your server.

That decision is based on behavior, not assumptions.

If the request is allowed, it continues normally. If it is blocked, it never reaches the origin. If it is challenged, the visitor is redirected to a custom human verification page.

Once the challenge is passed, a short-lived cookie is issued to establish temporary trust. From that point on, the visitor continues without being challenged again.

Your origin only sees traffic that has already passed an intent check.

Why a custom challenge exists

CAPTCHAs work, but they come at a cost.

They interrupt users, rely on third-party scripts, and often introduce tracking and fingerprinting into places where it doesn’t belong.

IPIntel uses a custom challenge page instead.

No external scripts. No fingerprinting. No tracking.

The goal is simple: verify that a real human is present, establish short-term trust, and get out of the way.

Cloudflare and IPIntel together

Cloudflare solves problems of scale.

IPIntel solves problems of context.

Cloudflare protects the edge. IPIntel adds judgment to it.

Used together, they allow unwanted traffic to be filtered earlier, reduce origin load, and avoid overly aggressive rules that end up breaking legitimate users.

IPIntel does not try to out-Cloudflare Cloudflare. It fills the gap Cloudflare intentionally leaves open.

Privacy and data handling

The IPIntel Cloudflare Worker is designed with minimal data use in mind.

There are no tracking scripts, no fingerprinting, and no persistent identifiers. Decisions are made using IP addresses and minimal request metadata required for threat detection.

The verification cookie used after a challenge is short-lived and exists only to avoid repeatedly challenging the same visitor. It is not used for tracking and is not shared across sites.

Closing thoughts

If Cloudflare is the shield, IPIntel is the judgment behind it.

Together, they don’t just block traffic. They make smarter decisions about it, before it ever reaches your application.

That difference matters.
