PCI DSS asks a lot of the laptops, desktops and phones that touch your card data environment. trio.so sets the required settings on every device, checks that they stay on, and gives you the evidence your assessor asks for. It covers Windows, macOS, Linux, iOS/iPadOS and Android from one console.

Card data stays on the terminal, but the laptops and phones next to it are in scope too. PCI DSS reaches every company or employee owned device that connects to your card data environment. trio.so sets the required controls on each one, checks that they stay on, and keeps the record your assessor asks for.
How it works
Checks usually live in three tools, and the proof in a spreadsheet. trio.so automates the device checks instead: you turn on the PCI DSS framework, see which devices fail which controls, and fix the settings with policies from the same console. It keeps checking on the schedule you set.
Requirements
Most of PCI DSS covers your payment systems and processes. Here is how trio.so helps with the device requirements, and where the proof lives.
Applies firewall and other security settings as managed policies on every enrolled device, company owned or personal.
Policy status for each device, and firewall check results.
Enforces passcode, disk encryption, firewall, USB storage blocking on Windows and Linux, and WPA2 or WPA3 Wi-Fi.
Findings for each control, device by device.
Checks that anti-malware is active on each computer, and shows Microsoft Defender for Endpoint alerts per device.
Check results for each device, with Defender alerts beside them.
Ranks vulnerabilities by CVSS, EPSS and the KEV list, then patches the OS and third party apps on your schedule.
Patch history: each job, the devices it reached and the result.
Passcode policies set auto-lock time, minimum length and lockout after failed attempts. A check confirms screen lock is on.
Screen lock check results and passcode policy status for each device.
Lists each device's owner, serial number, OS and installed apps.
A device list you can export as CSV whenever you need it.
Requirement numbers from PCI DSS v4.0.1 (June 2024).
Controls
Settings drift between audits. trio.so sends policies to every enrolled device, and their status comes back: applied, failed or pending, device by device. Scheduled checks confirm the settings stay on.
Remediation
A fix nobody checks is a guess. When a device fails a control, you fix the setting with a policy, the next check confirms it, and trio.so logs every step, so the history is ready when your assessor asks.
Start a free trial, enroll a few devices and turn on the PCI DSS framework. The findings fill in from your own fleet.
Every OS
Each operating system reports different signals, so the depth differs. Here is what trio.so checks on each, so you know what your evidence covers.
macOS: screen lock, FileVault, firewall, Secure Boot, OS updates and anti-malware. Windows: BitLocker, firewall, Secure Boot, OS updates and anti-malware. Plus the status of every policy.
Posture signals such as disk encryption, firewall and OS updates, plus the status of core policies.
Whether passcode, encryption and other policies are applied on each phone and tablet, including Android work profiles.
Evidence
Screenshots go stale the day after you take them. Assessors ask you to show that a control is in place, not just that a policy exists, and trio.so keeps that record as it works.
Why trio.so
Another tool is another place to check. Most teams keep a compliance spreadsheet next to their MDM and their patch tool. trio.so checks, tracks fixes and records in the console that already manages the devices.
Policies, checks, patches, inventory and remote actions share one device record.
Plans start at $5 per device. Endpoint compliance is in the Secure plan and above.
Support from real people 24 hours a day, Monday to Friday.
