The Challenge
Obfuscated Challenges
Imperva (formerly Incapsula) relies on heavily obfuscated JavaScript challenges (UTMVC) and sensor data collection (Reese84) to distinct humans from bots.
Our Solution
Dynamic Script Execution
Our remote execution environment processes the necessary challenge logic to produce valid session and tracking cookies for backend compatibility.
- reese84 sensor data generation
- utmvc cookie calculation
- incap_ses session handling
- visid_incap creation

Integration is easy
Stop fighting with headless browsers. Get the cookie you need in a single API call and attach it to your rigid HTTP client.
const response = await fetch('/v1/tasks/submit', {
method: 'POST',
body: JSON.stringify({
service: 'utmvc',
url: 'https://example.com'
})
});
// Returns valid reese84
