AWS Security Services: Native Tools vs. What You Still Need
AWS ships an impressive suite of native security services. GuardDuty, Security Hub, Macie, Inspector, Config - each solving a real security problem within the AWS ecosystem. But AWS's native services have gaps, and understanding those gaps is essential for building a complete cloud security program.
This guide maps AWS native security services against what they cover, what they miss, and what you need alongside them.
AWS Native Security Services: A Practical Map
| AWS Service | What It Does Well | Key Limitation |
|---|---|---|
| AWS Config | Tracks configuration changes, compliance rules | Limited remediation support, no workflow integration |
| Amazon GuardDuty | Threat detection from CloudTrail/DNS/VPC Flow Logs | No misconfiguration detection |
| AWS Security Hub | Aggregates findings from multiple sources | Still requires manual triage and routing |
| Amazon Macie | Sensitive data discovery in S3 | S3 only, no broader data classification |
| Amazon Inspector | Vulnerability scanning for EC2 and containers | Limited to compute, no cloud-level misconfigs |
| AWS IAM Access Analyzer | Identifies overly-permissive resource policies | IAM and resource policies only |
| CloudTrail | API activity logging | Analysis and threat detection requires additional tooling |
| AWS WAF | Web application firewall | Requires careful rule configuration, no API discovery |
What AWS Native Services Do Well
GuardDuty: Excellent Threat Detection
GuardDuty is one of AWS's best security investments. It analyzes CloudTrail logs, DNS queries, and VPC Flow Logs using threat intelligence to detect:
- Unusual API call patterns that may indicate compromised credentials
- Communication with known malicious IP addresses
- Cryptocurrency mining activity
- S3 anomalous access patterns
At $0.55–$4 per million events (depending on data source), it's cost-effective for the detection capability it provides. Enable it in every account, in every region. There's no reason not to.
AWS Config: Solid Compliance Foundation
Config maintains a timeline of resource configuration changes and supports custom compliance rules via AWS Config Rules (including a large library of managed rules). For organizations building around CIS AWS Benchmark compliance, Config rules provide a native implementation of many required checks.
The limitation is that Config rules tell you when something is non-compliant - they don't help you fix it or route the finding to the right engineer.
Security Hub: Good Aggregation, Weak Remediation
Security Hub aggregates findings from GuardDuty, Inspector, Macie, Config, and third-party tools into a single view. This is genuinely useful for large security teams running a dedicated SOC operation.
For smaller teams, Security Hub findings without a downstream remediation workflow still pile up without getting addressed. The findings are accurate - the workflow is missing.
What AWS Native Services Don't Do
Misconfiguration remediation workflow: AWS native services detect issues but provide no structured workflow to route findings to the responsible engineer, track remediation status, or collect evidence that the fix was applied.
Cross-domain correlation: An EC2 instance with a permissive security group (security finding) that's also oversized and idle (cost finding) appears as separate signals in AWS tools. An integrated platform like Dedups.ai surfaces these as a single resource issue.
Cost optimization: AWS Cost Explorer and Trusted Advisor provide basic cost optimization guidance, but lack the ML-driven recommendations, workflow integration, and evidence tracking of a dedicated platform.
API security: AWS doesn't provide comprehensive API discovery and security testing. Third-party tools are required.
IP vulnerability scanning: AWS Inspector scans EC2 instances for known CVEs. External attack surface scanning requires separate tooling.
Building the Complete Picture
A practical AWS security program combines native services with third-party tooling:
Use AWS native services for: Threat detection (GuardDuty), log collection (CloudTrail), data discovery (Macie), configuration history (Config)
Supplement with Dedups.ai for: Misconfiguration detection with remediation workflow, cost optimization, API security, IP vulnerability scanning, compliance evidence generation, and engineering-workflow integration

AWS native security services are a strong foundation - but they're not a complete security program. Dedups.ai fills the critical gaps in the AWS native security stack, particularly around misconfiguration remediation, cost optimization, and API security.
