Excellent question — these four AWS services (Audit Manager, Config, Inspector, and Artifact) all relate to security, compliance, and governance, but they serve very different purposes within that ecosystem.
Let’s break them down in a clear, structured way 👇
🧩 High-Level Summary
| Service | Primary Purpose | Type |
|---|---|---|
| AWS Audit Manager | Continuously collects evidence and automates audit reporting for compliance frameworks | Compliance reporting tool |
| AWS Config | Tracks configuration changes and checks AWS resources against compliance rules | Configuration monitoring tool |
| Amazon Inspector | Scans workloads for vulnerabilities and security issues | Security assessment tool |
| AWS Artifact | Provides on-demand access to AWS compliance reports and agreements | Compliance documentation portal |
🧠 1. AWS Audit Manager
🔹 Purpose:
Helps you audit your AWS environment automatically to simplify compliance with frameworks like ISO 27001, GDPR, PCI-DSS, SOC 2, etc.
⚙️ How It Works:
Continuously collects evidence (data points) from AWS services (like Config, CloudTrail, IAM).
Maps them to control sets defined by compliance frameworks.
Generates audit-ready reports automatically.
📋 Key Features:
Prebuilt compliance frameworks and control mappings.
Automated evidence collection (no manual screenshots or data gathering).
Integration with AWS Organizations (multi-account audits).
Custom frameworks for internal governance.
🧭 Best For:
Compliance teams or auditors.
Organizations preparing for certifications or audits.
🧩 Example:
“Show me all evidence that IAM users require MFA.”
Audit Manager automatically gathers this proof over time.
⚙️ 2. AWS Config
🔹 Purpose:
Tracks and records configuration changes of AWS resources to ensure they remain compliant with desired settings or internal policies.
⚙️ How It Works:
Continuously records resource configurations (EC2, IAM, S3, VPC, etc.).
Allows you to define Config Rules (managed or custom using Lambda).
Detects non-compliant resources and triggers alerts or remediation.
📋 Key Features:
Real-time configuration tracking and history.
Compliance evaluation against internal or AWS standards.
Integration with CloudTrail and Security Hub.
🧭 Best For:
DevOps, security, and compliance teams wanting configuration drift detection.
Maintaining continuous resource compliance posture.
🧩 Example:
“Alert me if any S3 bucket becomes public.”
AWS Config continuously monitors and flags such violations.
🛡️ 3. Amazon Inspector
🔹 Purpose:
An automated vulnerability management service that scans workloads for security issues.
⚙️ How It Works:
Automatically discovers EC2 instances, container images (ECR), and Lambda functions.
Continuously scans for:
CVEs (Common Vulnerabilities and Exposures)
Misconfigurations
Software package vulnerabilities
Prioritizes findings by severity (CVSS score, exploitability).
📋 Key Features:
Continuous vulnerability scanning.
Agentless scanning for EC2 and container images.
Integration with AWS Security Hub, EventBridge, and Inspector dashboard.
Automatic remediation support.
🧭 Best For:
Security operations and compliance monitoring.
Continuous vulnerability assessment of compute resources.
🧩 Example:
“Detect and alert if any EC2 instance has a vulnerable OpenSSL version.”
📄 4. AWS Artifact
🔹 Purpose:
A self-service portal that provides AWS compliance reports, certifications, and agreements (e.g., SOC, ISO, PCI, GDPR).
⚙️ How It Works:
You access it from the AWS Console (no setup required).
Download third-party audit reports of AWS infrastructure.
Accept compliance agreements (e.g., Business Associate Addendum (BAA) for HIPAA).
📋 Key Features:
Central access to AWS’s own compliance evidence.
No cost; just authentication required.
Up-to-date compliance documentation and certifications.
🧭 Best For:
Compliance and legal teams.
Customers needing AWS compliance proof for audits.
🧩 Example:
“I need AWS’s SOC 2 Type II report to show my auditor.”
You download it directly from AWS Artifact.
⚖️ 5. Key Differences
| Feature | AWS Audit Manager | AWS Config | Amazon Inspector | AWS Artifact |
|---|---|---|---|---|
| Purpose | Automate collection of audit evidence | Monitor resource configurations | Detect vulnerabilities | Provide AWS compliance reports |
| Focus Area | Compliance automation | Configuration compliance | Security posture & CVE detection | External compliance documentation |
| Scope | Organization-level audits | Resource-level state | Instance, container, Lambda-level scanning | AWS infrastructure compliance |
| Customization | Custom frameworks | Custom Config rules | Custom scan targets | None (read-only portal) |
| Output | Audit reports, control evidence | Compliance dashboard | Vulnerability findings | Downloadable reports (PDF) |
| Integration with Others | Uses Config, CloudTrail, IAM data | Feeds data to Audit Manager, Security Hub | Integrates with Security Hub | Standalone portal |
| User Role | Auditors & compliance officers | DevOps/SecOps | Security engineers | Compliance/legal staff |
🧩 6. How They Work Together
Here’s how they complement each other in a real compliance workflow:
AWS Config → Monitors your resource configurations.
Amazon Inspector → Scans for vulnerabilities in EC2, ECR, Lambda.
AWS Audit Manager → Collects evidence from Config, Inspector, IAM, etc., and maps it to compliance controls (e.g., SOC 2).
AWS Artifact → Provides the official AWS compliance documentation to share with auditors.
📊 Example Flow:
Config detects non-compliant S3 → Inspector detects a vulnerability → Audit Manager collects both as audit evidence → Artifact provides AWS’s ISO report for your compliance pack.
🧠 Simple Analogy
| Service | Analogy |
|---|---|
| Audit Manager | Your automated audit assistant (collects compliance evidence) |
| Config | Your compliance monitor (tracks changes and deviations) |
| Inspector | Your security scanner (finds vulnerabilities) |
| Artifact | Your compliance library (stores AWS certifications and reports) |
Would you like me to add a diagram showing how these four services connect in a compliance architecture (e.g., flow from Config → Inspector → Audit Manager → Artifact)? It visually clarifies their interaction.
