The device, the app, the cloud.
We test the whole chain.
A connected device is never alone. It talks to a mobile app, a wireless link, and a cloud backend, and attackers hop from the weakest one to the rest. We test the whole ecosystem, from the chip to the cloud.


















The question that matters
Your device is secure.
Your app is secure.
Your cloud is secure.
But has anyone tested what happens when an attacker moves between them?
Your app is secure.
Your cloud is secure.
But has anyone tested what happens when an attacker moves between them?
WHY MOST IoT Security TESTINGs FALL SHORT
Testing the device alone leaves the doors around it open
The device is only part of the story. The app that controls it, the wireless protocols, and the cloud it reports to are all ways in. Test one and skip the rest, and you've left the easy paths open.
Most IoT Security Vendors
Scan the network and calls it done
Use automated tools to find debug ports
Give up on chips that are hard to read
Run automated scans only
One tester for the whole device
Send a report and exits
Payatu
Opens the device up: full hardware teardown and PCB board analysis
Finds hidden debug ports manually, even when tools can't
Pulls firmware off any chip, however protected
AI-native and research-led: our own tools (EXPLIoT, BUS Auditor) plus deep manual analysis
A specialist for each part: hardware, firmware, and wireless protocol
Ranks findings by severity, then re-tests the fixes
What we test
Chip to cloud
We scope to what matters most in your device, then test every layer a real attacker would.

Process
How it works
Simple, step by step, from opening the device to confirming the fix.
Understand the device
You tell us what the device does and what matters most. We plan the test around it.
01
Open it up
We take the device apart, map the board, and find the ports and chips worth attacking.
02
Attack the whole system
We go after the wireless, the app, and the cloud, and see how far one weak link goes.
04
Get the firmware
We pull the firmware off the device and read it for passwords, keys, and flaws.
03
Explain what we found
Every issue in plain language, ranked by how much it would hurt the business.
05
Fix
We offer remediation support to fix each issue.

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.
