Manual vulnerability management is resource-intensive and can delay remediation. By integrating with AWS services like Amazon Event Bridge and AWS Systems Manager, Amazon Inspector enables automated workflows to address findings quickly and efficiently.

  • Trigger-Based Workflows: Inspector findings can initiate automated workflows to apply patches, isolate affected resources, or notify security teams.

  • Real-Time Alerts: Security teams can stay informed about critical vulnerabilities through integrated alerts in Security Hub or SNS.

  • Custom Actions: Event Bridge rules allow businesses to design custom responses tailored to their operational needs.

Example Use Case:

An e-commerce giant integrates Amazon Inspector with Event Bridge to automate responses to critical vulnerabilities. When Inspector identifies a high-risk issue on an EC2 instance, Event Bridge triggers a patching process via AWS Systems Manager. If immediate remediation isn't possible, the instance is automatically isolated to prevent lateral movement.

Additional Use Cases

4.4 Securing Hybrid Environments

Inspector supports hybrid environments by assessing vulnerabilities on AWS resources and connected on-premises workloads, ensuring comprehensive protection.

Example: A multinational bank with a hybrid setup uses Inspector to monitor EC2 instances on AWS and on-premises servers connected via AWS Outposts.

By integrating with DevOps pipelines, Inspector ensures security checks are embedded early in the development lifecycle, promoting a DevSecOps culture.

Example: A software development company integrates Inspector into its Jenkins pipeline to scan container images during build stages, ensuring security before deployment.

5. Pricing Updates and Cost-Effectiveness

Amazon Inspector’s updated 2024 pricing model continues to offer flexibility while introducing features that cater to cost-conscious organizations. By focusing on usage-based billing and volume discounts, it ensures affordability and scalability for businesses of all sizes.

5.1 Pay-Per-Scan Model

Amazon Inspector employs a straightforward pay-per-scan pricing approach:

  • Resource-Based Costs: Charges are applied based on the type and number of resources scanned. For instance, scanning an EC2 instance, ECR container image, or Lambda function incurs specific charges.

  • Cost Alignment with Usage: Organizations only pay for the resources they scan, making it a cost-effective solution for environments with varying workloads.

Example

A small startup runs monthly scans on 50 EC2 instances to maintain security. With the pay-per-scan model, the startup avoids paying for unused resources, keeping costs minimal while maintaining security standards.

5.2 Volume Discounts

New in 2024, Amazon Inspector introduces tiered pricing, offering discounts as scan volumes increase. This benefits larger organizations with extensive environments, helping them achieve significant cost savings.

  • Discount Thresholds: Pricing becomes progressively lower as the number of scans crosses specific volume thresholds.

  • Scalability Without High Costs: Larger environments can maintain comprehensive security coverage while staying within budget.

Example

A global retail enterprise scans 10,000 container images monthly for vulnerabilities. By surpassing discount thresholds, they receive a reduced rate per image, saving thousands of dollars annually compared to flat-rate pricing.

5.3 Free Tier for Exploration

Inspector’s extended free tier, introduced in 2024, offers:

  • 1,000 Free Lambda Scans or 10 Free Container Image Scans per month for the first year.

  • Encourages businesses to evaluate the service without upfront investment.

Example

A medium-sized software firm evaluates Inspector's capabilities by leveraging the free tier to scan its most critical Lambda functions. This enables them to assess the tool’s value before committing to larger-scale usage.

5.4 Cost-Effectiveness in Action

Inspector’s pricing ensures businesses get robust security coverage without overspending. The combination of usage-based pricing and discounts allows organizations to allocate resources efficiently.

Example Pricing

Use Case: A technology company secures its workloads using Amazon Inspector for EC2 instances, container images in Amazon ECR, and Lambda functions.

Workloads:

  • 100 EC2 Instances scanned monthly.

  • 500 ECR Container Images scanned monthly.

  • 2,000 Lambda Functions scanned monthly.

Estimated Costs

1. EC2 Instance Scans

  • Per-instance cost: $0.30 per scan (example rate, subject to change).

  • Monthly cost: 100 instances × $0.30 = $30.00.

2. ECR Container Image Scans

  • Per-image cost: $0.20 per scan.

  • Monthly cost: 500 images × $0.20 = $100.00.

3. Lambda Function Scans

  • Per-function cost: $0.10 per scan.

  • Free tier: First 1,000 scans are free under the 2024 extended free tier.

  • Billable scans: 2,000 scans - 1,000 free = 1,000 billable scans.

  • Monthly cost: 1,000 functions × $0.10 = $100.00.

Volume Discount Savings

If the organization qualifies for a 10% discount after reaching a tiered threshold for combined scans (3,000+ scans), the cost is reduced:

  • Total scans = 100 (EC2) + 500 (ECR) + 2,000 (Lambda) = 2,600 (free tier excluded).

Assuming the discount applies:

  • Post-discount cost: $230.00 - 10% = $207.00.

So Final Monthly Cost

Total Cost: $207.00

Savings with Free Tier and Discounts: $30.00 from free Lambda scans + $23.00 from volume discounts.
