We find real vulnerabilities

Go beyond AppSec that drowns teams with false positives and trivial bugs.
Discover the business logic vulnerabilities traditional tools miss

Traditional security methods are failing against modern threats.

Human Pen Test

Validate business logic

Analyze every line of code

The dark corners of codebase that never get reviewed result in large blind spots and latent attack surfaces.

Rigid, rules-based testing finds bugs and well-known exploits, but not new attack techniques.

Xint gives your team focus and prioritization by identifying the vulnerabilities that attackers can actually exploit.

Even next gen AI tools can’t achieve the scale and depth of Xint’s analyses

AI tools are context-limited and thus can only look at small portions of code at a time. They are like a single worker dedicated to a single workstream at a time.

Xint spins up several AI agents, giving each one a specific task and orchestrates the overall workflow, such that you can do massive parallel analyses in a short amount of time.

What sort of business logic vulnerabilities has Xint caught and traditional approaches missed?

Ecommerce

Xint found users could add negative amounts to cart, leading to fraudulent card chargebacks

Fintech

Xint discovered a way users could create money in their accounts without depositing more, a “free money glitch”

Account Management

Xint uncovered that multifactor authentication mistakenly exposed verification code within redirect page, enabling improper account takeovers
