A weak API can harm a strong app

A low-risk flaw in one component plus an over-trusted connection to another adds up to a critical path.

We map how a mobile app leads to your API, how an API exposes your cloud, and how one weak link reaches everything.

The question that matters

Each finding looks low-risk on its own. But chained across your product, where does that path actually end?
WHY MOST PRODUCT TESTING FALLS SHORT

The dangerous flaws live in the trust between components

Strong authentication on your app means little if the API behind it trusts any request. Real attacks chain a small weakness here to an over-trusted connection there.

Testing components in isolation never sees those chains. We test the trust relationships, not just the parts.
Most Vendors
Separate testing per component
No integration or cross-component analysis
Individual vulnerabilities without context
Inconsistent security across components
Testing isolated from business priorities
Fragmented findings from different teams

Process

How it works

Simple, step by step, from first look to a product that stays secure.

Map the product

We learn your architecture, your critical functions, and how data flows between components.
01

Threat model it

We model how an attacker could chain weaknesses across your whole product.
02

Trace the attack paths

We show how a small flaw in one component opens a path to your crown-jewel data.
04

Test every component

Mobile, web, APIs, cloud, and IoT, tested individually and at the points where they connect.
03

One roadmap

Consolidated findings ranked by business impact, not separate reports to reconcile.
05

Keep it secure

Retesting and secure-design guidance as your product adds features and components.

Payatu delivered a 360-degree penetration testing exercise across our web applications and internal network. Their structured, methodical approach and deep technical understanding were evident throughout the engagement. They didn’t just give us a list of vulnerabilities, they provided actionable insights that helped to improve our security posture. The engagement was constructive.
