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?

Aristiun supports 340+ security and compliance frameworks including SOC 2, ISO 27001, HIPAA, GDPR, DORA, CMMC, PCI DSS, HITRUST CSF, NIST CSF, NIST 800-53, FedRAMP, CIS Controls, CCPA, EU AI Act, ISO 42001, and many more. The platform provides cross-framework control mapping to eliminate duplicate work.

How do you automate NIST 800-53 compliance?

In practice, it means connecting your infrastructure so the platform can map it to the 1,189 controls across 20 control families. From there, it collects evidence continuously and flags drift in real time. Aristiun's NIST 800-53 compliance tool uses Ayurak AI to discover your assets, map them to applicable control families (AC, AU, CA, CM, CP, IA, IR, and the rest), identify gaps, and generate audit-ready docs like System Security Plans and POA&Ms. The key difference from manual work: you stay compliant continuously, not just at audit time.

What is the difference between NIST CSF and NIST 800-53?

Here's the thing: NIST CSF is the high-level framework. It's organized around six functions (Govern, Identify, Protect, Detect, Respond, Recover) and any organization can use it. NIST 800-53 is the detailed catalog, with 1,189 security and privacy controls mainly required for federal agencies and contractors. Think of CSF as the 'what' and 800-53 as the 'how.' Aristiun's NIST CSF assessment platform maps between both, so you can assess against CSF outcomes while tracking the specific 800-53 controls that implement them.

How does the NIST Risk Management Framework (RMF) work?

The NIST RMF (SP 800-37) is a seven-step lifecycle: (1) Prepare, establish context and risk tolerance. (2) Categorize, classify systems by impact level using FIPS 199. (3) Select applicable security controls from NIST 800-53. (4) Implement those controls. (5) Assess whether they actually work. (6) Authorize, which means making the risk-based go/no-go decision. (7) Monitor control status on an ongoing basis. Aristiun's NIST RMF automated assessment platform walks you through each step and automates control selection, assessment, and continuous monitoring so your authorization stays current.

What are the 6 functions of NIST CSF 2.0?

The big change in 2.0 was adding Govern as a sixth function. Here's the full list: (1) Govern (GV), set your cybersecurity risk management strategy. (2) Identify (ID), know your assets, risks, and business context. (3) Protect (PR), put safeguards in place. (4) Detect (DE), spot cybersecurity events quickly. (5) Respond (RS), act on incidents. (6) Recover (RC), restore normal operations. Aristiun's NIST cybersecurity framework automation platform assesses all six, with automated control mapping and continuous posture measurement.

How do you map NIST controls to SOC 2 and ISO 27001?

Cross-framework mapping connects NIST 800-53 controls to equivalent requirements in SOC 2 Trust Services Criteria and ISO 27001 Annex A controls. For example, NIST AC-2 (Account Management) maps to SOC 2 CC6.1 (Logical Access Security) and ISO 27001 A.9.2.1 (User Registration). Manual mapping across hundreds of controls is error-prone and time-consuming. Aristiun maintains a continuously updated mapping database across 340+ frameworks, allowing you to assess once against NIST and automatically see your compliance posture against SOC 2, ISO 27001, HIPAA, FedRAMP, PCI DSS, CMMC, and more, eliminating redundant assessments.

What is the NIST AI Risk Management Framework (AI RMF)?

This is NIST's voluntary framework for AI risk. It has four functions: Govern (set AI risk policies), Map (understand where AI risks sit in your org), Measure (assess those risks with real data), and Manage (prioritize and act). It tackles AI-specific concerns like bias, explainability, privacy, and reliability. Aristiun's NIST AI RMF assessment capabilities evaluate your AI systems against all 19 subcategories, with specialized analysis for LLMs, ML pipelines, and AI-powered applications.

How long does a NIST assessment take with automation?

Most teams spend 3 to 6 months on a manual NIST 800-53 assessment, at a cost of $150K to $500K in consulting fees. With Aristiun's NIST risk assessment automation platform, initial assessments wrap up in days to weeks. The platform maps your architecture to applicable controls, runs gap analysis, collects evidence, and generates reports. But here's what really matters: it turns compliance from a periodic fire drill into a continuous process. The platform monitors your environment 24/7 and alerts you to drift in real time, so you skip the annual scramble.

FAQ

NIST Risk Assessment: Frequently Asked Questions

Everything you need to know about NIST based assessment, NIST SP 800-37 risk management, and how to automate NIST cybersecurity framework compliance.

The short answer: it's a structured evaluation of your cybersecurity posture using NIST frameworks. The most common ones are NIST 800-53 (security and privacy controls), NIST CSF (Cybersecurity Framework), and NIST SP 800-37 (Risk Management Framework). You use them to find security gaps, measure how mature your controls are, and build a remediation roadmap tied to federal standards. Aristiun automates the full NIST based assessment lifecycle, from control mapping through continuous monitoring. Most customers go from kickoff to first results in days, not months.
