What we stop

Fraud and abuse that cost you money every day.

Kavra finds the people and bots behind abuse before they reach your promotions, your accounts and your margins.

What we detect

Whatever fraudsters use to hide, Kavra sees through it.

From bots and disguised devices to proxy networks and human-like scripts, Kavra’s AI/ML models are trained on the full toolkit fraudsters use today, and keep learning as it changes.

  • Automation and bots

    Headless browsers, automation frameworks, scripts and scrapers, including “stealth” setups.

    • Playwright
    • Puppeteer
    • Selenium
    • Headless Chrome
    • Scripts

  • Environment spoofing

    Antidetect browsers, virtual machines and emulators that fake a device to look like someone new.

    • Antidetect browsers
    • VMs
    • Emulators
    • Device farms

  • Network intelligence

    Where traffic really comes from, even behind residential and mobile proxies.

    • Residential proxies
    • Mobile proxies
    • VPN
    • Tor
    • Datacenters

  • Behavioral analysis

    How a visitor moves, types and navigates: a person, or a script imitating one.

    • Pointer
    • Typing rhythm
    • Navigation
    • Velocity

  • Identity and device linking

    One actor behind many accounts and sessions, recognized across visits and new disguises.

    • Multi-accounts
    • Returning devices
    • Fingerprint rotation

  • AI agents and good bots

    Verified crawlers and AI agents let in, impostors pretending to be them flagged.

    • OpenAI agents
    • Search crawlers
    • Unverified bots

Multi-layer protection

Every request passes through every layer.

Kavra examines each visit on several layers at once — network, device, browser, behavior and history. Then an AI/ML risk engine weighs everything it found into one clear decision. A disguise that fools one layer is caught by the next.

  • 3,000+ data points analyzed on every visit
  • Machine-learning models that keep learning from new fraud patterns
  • A decision in milliseconds, invisible to real customers

FAQ

Questions we hear most.

Can’t find yours? Talk to our team.

Will Kavra block my real customers?

No. Kavra works in the background and gives you a recommendation with the reason. You decide what to do, and you can start in observe-only mode to see results before blocking anything.

How long does integration take?

Minutes for the script on your site and one API call on your backend. Most teams see their first results the same day.

Does it slow down my website?

No. The script is under 64 KB, loads in the background and never blocks your page. Analysis happens on our servers, not in your visitor’s browser.

Can fraudsters get around it with an antidetect browser?

Antidetect browsers change what a browser says about itself. Kavra checks the network, device, browser and behavior together, and a disguise that fools one layer rarely fools all of them. Changing the fingerprint is itself a signal we detect.

How does Kavra handle GDPR?

Kavra needs no names or emails. It applies the legal basis per visitor region, respects your consent manager, identifies visitors by pseudonymous IDs and never shares your data with other customers. Technical signals such as IP addresses are treated as personal data and described in our privacy policy; see also security and privacy.

What about good bots like Google and AI agents?

Verified search engines and AI agents are recognized and reported separately. You choose whether to let them in, check them or block them.
