What is automated threat modeling?

Automated threat modeling uses AI to identify, classify, and prioritize security threats across your infrastructure and applications. Aristiun's Unified Threat Workbench powered by Ayurak AI lets you upload diagrams, collaborate in real time, and generate secure architectures with AI copilots. It automates STRIDE, PASTA, LINDDUN, and MAESTRO methodologies to continuously map your threat landscape against 340+ compliance frameworks.

Modern GRC (Governance, Risk, and Compliance) replaces legacy spreadsheet-based compliance with AI-powered automation. Aristiun's modern GRC platform provides real-time compliance scoring, automated evidence collection, cross-framework control mapping, and continuous monitoring across 340+ standards including SOC 2, ISO 27001, HIPAA, GDPR, and DORA.

How does Aristiun handle AI Governance and EU AI Act compliance?

Aristiun provides comprehensive AI governance covering the EU AI Act, NIST AI RMF, ISO 42001, and ISO 23894. The platform automates AI risk classification, model inventory management, bias monitoring, transparency reporting, and evidence collection to ensure your AI systems comply with global AI regulations.

How many compliance frameworks does Aristiun support?

PCI DSS Compliance Guide

PCI DSS v4.0 Compliance Automation

Automate PCI DSS v4.0 compliance with AI-powered cardholder data environment monitoring. Aristiun ensures continuous protection of payment card data with automated control validation, evidence collection, and SAQ/ROC reporting.

What is PCI DSS?

PCI DSS (Payment Card Industry Data Security Standard) v4.0 is the global standard for protecting payment card data. Released in March 2022 with mandatory compliance from March 31, 2025, PCI DSS v4.0 introduces 64 new requirements including customized approach validation, enhanced authentication requirements, and expanded scope for e-commerce. It applies to any organization that stores, processes, or transmits cardholder data — merchants, payment processors, acquirers, issuers, and service providers.

PCI DSS Key Requirements

The core areas you need to address for PCI DSS compliance.

Build and Maintain a Secure Network

Install and maintain network security controls (firewalls, network segmentation). Apply secure configurations to all system components.

Protect Cardholder Data

Protect stored account data with encryption. Protect cardholder data with strong cryptography during transmission over open, public networks.

Maintain a Vulnerability Management Program

Protect all systems and networks from malicious software. Develop and maintain secure systems and software.

Implement Strong Access Control

Restrict access to cardholder data by business need-to-know. Identify users and authenticate access. Restrict physical access to cardholder data.

Monitor and Test Networks

Log and monitor all access to network resources and cardholder data. Regularly test security systems and processes, including penetration testing.

Maintain an Information Security Policy

Establish, publish, maintain, and disseminate a security policy that addresses all PCI DSS requirements.

PCI DSS Compliance Checklist

Step-by-step checklist to achieve and maintain PCI DSS compliance.

Define and document your cardholder data environment (CDE) scope

Implement and maintain network segmentation and firewall rules

Encrypt stored cardholder data and data in transit

Deploy and maintain anti-malware solutions

Develop and maintain secure coding practices

Implement role-based access controls for CDE access

Deploy multi-factor authentication for all CDE access (new in v4.0)

Implement logging and monitoring for all CDE activity

Conduct regular vulnerability scans (ASV) and penetration tests

Perform targeted risk analysis for each PCI DSS requirement (new in v4.0)

Prepare SAQ or ROC documentation for QSA assessment

PCI DSS Compliance FAQ

Common questions about PCI DSS compliance and automation.

What's new in PCI DSS v4.0?

PCI DSS v4.0 introduces 64 new requirements including: customized approach for meeting objectives, enhanced multi-factor authentication, targeted risk analysis for each requirement, expanded e-commerce and phishing protections, and updated encryption standards. Organizations had until March 31, 2025 to comply with the new requirements.

Who needs PCI DSS compliance?

Any organization that stores, processes, or transmits payment card data must comply with PCI DSS. This includes merchants, payment processors, acquirers, issuers, and service providers. Even if you use a third-party processor, you still have PCI DSS obligations.

How does Aristiun automate PCI DSS compliance?

Aristiun automates PCI DSS through AI-powered CDE scope discovery, automated control validation across all 12 requirements, continuous network monitoring, vulnerability scan management, evidence collection, and audit-ready SAQ/ROC report generation. Cross-framework mapping with SOC 2 and ISO 27001 eliminates redundant work. Powered by Ayurak AI.
