15 best AWS security tools for 2026: native services and third-party platforms

The best AWS security tools for 2026 are eight native services (AWS Security Hub, Amazon GuardDuty, Amazon Inspector, AWS Config, Amazon Macie, Amazon Detective, AWS Security Incident Response and AWS Security Agent) and seven third-party platforms (Upwind, Wiz, Orca Security, Microsoft Defender for Cloud, Prowler, Aqua Security and Splunk Enterprise Security). Most AWS teams need both. Native services generate signals inside each account at low setup cost. External platforms add cross-account context, runtime evidence and multi-cloud coverage. The tools also overlap heavily, so one exposed S3 bucket or vulnerable EC2 instance can appear as three separate findings. This guide is current as of October 2026. It maps each tool to the AWS services it covers, states its limits and shows which combinations avoid paying twice for the same capability.

Quick shortlist of the 15 best AWS security tools

The 15 best AWS security tools fall into five categories: aggregation and posture, threat detection and investigation, vulnerability management, data security, and unified CNAPP or SIEM platforms.

The acronyms in this guide map to distinct types of cloud security tools:

• CSPM checks cloud configurations, such as public S3 buckets or open security groups.
• CWPP protects workloads such as EC2 instances, containers and Lambda functions.
• CIEM finds over-permissioned, unused or toxic IAM entitlements.
• CDR detects and responds to active threats in cloud control and data planes.
• DSPM discovers and classifies sensitive data stores.
• CNAPP combines these layers in one platform with a shared asset graph.

How we selected and scored the tools

We scored each tool against eight weighted criteria that reflect AWS-specific buying decisions, using vendor documentation, published integration lists and Gartner Peer Insights reviews rather than marketing claims.

Integration depth and signal quality carry the most weight because they decide whether a tool reduces work or adds to it. A scanner that reports every installed CVE at its CVSS score creates a queue. A scanner that checks whether the package is loaded in memory, reachable from the internet and listed as actively exploited creates a priority list.

Upwind and AWS-native security services (tools 1–9)

AWS-native security services cover detection, posture, vulnerabilities and data inside AWS at low setup cost, but each one handles a single job and stops at the AWS boundary.

1. Upwind

Upwind is a runtime-first CNAPP that pairs agentless discovery of AWS accounts with lightweight eBPF sensors on EC2 instances and EKS nodes. It does not rank Inspector, Config and GuardDuty signals by static severity alone. Instead, it uses runtime evidence to show which vulnerable packages are actually loaded and reachable, which IAM roles are actually used, which APIs actually carry sensitive data and which threats are actually unfolding. One sensor and one platform cover CSPM, CWPP, CIEM, vulnerability management, Kubernetes, API security, DSPM, AI workloads (AI-SPM and AI-DR) and CDR across AWS, Azure and GCP.

Strengths

• ✓Turns long Inspector-style CVE queues into a priority list by checking whether each vulnerable package is loaded, reachable and internet-exposed on EC2 and EKS.
• ✓Its CIEM separates the IAM roles and permissions workloads actually use from over-permissioned, unused or toxic combinations, which helps architects cut AWS identity risk.
• ✓Agentic Pack AI agents investigate threats, validate exposure and generate fixes from runtime context rather than static posture data. This shortens SOC investigations of cloud activity.
• ✓Integrates with the AWS Security Hub extended plan, so Security Hub can remain the native system of record. Gartner Peer Insights reviewers rate it 4.8/5 across 88 reviews and highlight its runtime visibility and lower alert noise.

Pricing: quote-based. It is listed on AWS Marketplace.

2. AWS Security Hub

Security Hub collects findings from GuardDuty, Inspector, Config, Macie, AWS WAF and partner tools through Amazon EventBridge and normalizes them into the AWS Security Finding Format (ASFF), a shared JSON schema with fields for resource, severity and compliance status. It assesses accounts against AWS Foundational Security Best Practices, AI Security Best Practices, CIS AWS Foundations Benchmark, NIST SP 800-53 Rev. 5, NIST SP 800-171 Rev. 2 and PCI DSS.

Strengths

• ✓Detects unused IAM roles, permissions and credentials across the organization from 90 days of access activity, and offers least-privilege recommendations.
• ✓Integrates with Splunk Enterprise Security, IBM QRadar, Elastic, Cortex XSOAR, Jira Service Management, ServiceNow, PagerDuty, Opsgenie and Slack.

Limitations

• ✗It aggregates rather than detects, so threat and CVE depth depends on GuardDuty and Inspector being enabled.
• ✗It covers AWS only, so it cannot be the posture view for Azure or GCP estates.

Pricing: tied to accounts plus findings and security checks; confirm the current billing unit before an organization-wide rollout. It is also available through AWS Marketplace.

3. Amazon GuardDuty

GuardDuty is the continuous threat detection layer for AWS. It flags unusual API calls, unexpected role assumptions, logging evasion and other attacker patterns, and it feeds Security Hub, Detective and third-party CDR tools.

Strengths

• ✓Suppression rules mute approved behavior, such as specific IPs or resource types, without disabling detection.
• ✓Third-party CDR platforms ingest its feed, so it stays useful after you add a CNAPP.

Limitations

• ✗Its findings lack the vulnerability, configuration and identity context that CNAPPs add.
• ✗It covers AWS only.

Pricing: AWS pay-as-you-go billing. Estimate per-account cost before enabling it across the organization.

4. Amazon Inspector

Inspector is AWS’s cloud vulnerability scanner for EC2 instances and container images. It also runs CIS benchmark assessments and can add security checks to CI/CD pipelines alongside Lambda.

Strengths

• ✓Findings flow into Security Hub with no extra connectors.

Limitations

• ✗It assesses what is installed, not whether a vulnerable package is loaded or reachable at runtime, so CVE backlogs stay long.
• ✗It covers AWS workloads only.

Pricing: AWS pay-as-you-go billing. The number of scanned instances and images drives cost.

5. AWS Config

Config records resource configurations and runs the posture and best-practice checks that feed Security Hub controls.

Strengths

• ✓Configuration history gives auditors point-in-time evidence for PCI DSS and NIST controls.

Limitations

• ✗Rules evaluate resources one at a time, so Config cannot tell you that a misconfigured security group sits in front of a vulnerable instance holding an admin role.

Pricing: AWS pay-as-you-go billing. The volume of recorded configuration items drives cost.

6. Amazon Macie

Macie discovers sensitive data in S3 and sends data security findings to Security Hub. Use it to answer one question: does this public or cross-account bucket actually hold PII, credentials or financial data?

Strengths

• ✓It is the native way to add data sensitivity to S3 exposure findings.

Limitations

• ✗It focuses on S3, so data in RDS, DynamoDB or EBS needs another tool.

Pricing: AWS pay-as-you-go billing. The volume of data scanned drives cost.

7. Amazon Detective

Detective collects large volumes of AWS log data and combines AI, statistical analysis and graph theory to investigate incidents. Responders typically open it after a GuardDuty finding to trace which role, IP address and resources were involved.

Strengths

• ✓It speeds root-cause analysis without exporting CloudTrail to a SIEM.

Limitations

• ✗It investigates threats but does not prevent them, and its value depends on GuardDuty being enabled.

8. AWS Security Incident Response

AWS launched Security Incident Response in December 2024 to triage and respond to threats. AWS responders and your team work cases together, and the service uses GuardDuty suppression rules and Security Hub CSPM automation rules to close known-good activity.

Strengths

• ✓It gives teams without a 24×7 cloud IR function access to AWS responders.

Limitations

• ✗It is a service rather than a detection engine, and it is scoped to AWS.

9. AWS Security Agent

AWS unveiled AWS Security Agent in preview at re:Invent 2025 as an agent designed to secure applications throughout development.

Strengths

• ✓It moves AWS-native security into the development lifecycle instead of limiting it to runtime posture.

Limitations

• ✗It launched as a preview, so check availability and regional coverage before you plan a program around it.

Third-party AWS security platforms (tools 10–15)

Third-party AWS security platforms correlate vulnerabilities, identities, exposure and runtime behavior, which native services do not, and they cover clouds beyond AWS. For a broader category view, see our list of the best CNAPP tools.

Two deployment models dominate. Agentless platforms read cloud APIs and copy block-storage snapshots to scan disks out of band, which gives fast coverage with nothing installed. Sensor-based platforms run eBPF programs inside the Linux kernel to observe process launches, network connections and file access as they happen, which shows what actually executes. Neither model can place a sensor where AWS gives no node access, such as Fargate.

10. Wiz

Wiz is an agentless CNAPP covering CSPM, CWPP, CIEM, CDR, vulnerability management, Kubernetes, API security, DSPM and AI security across AWS, Azure and GCP. It supports EKS, AKS, GKE and self-managed Kubernetes.

Strengths

• ✓Its CIEM calculates effective permissions, taking permission boundaries, service control policies (SCPs) and resource control policies (RCPs) into account, so it is good at finding AWS privilege escalation paths.
• ✓It prioritizes CVEs by reachability, packages loaded in memory, internet exposure and exploitability.
• ✓Gartner Peer Insights reviewers single out agentless onboarding and attack-path analysis.

Limitations

• ✗Its sensor cannot run on AWS Fargate, serverless platforms or managed services without node access.
• ✗One reviewer says detection and response is still maturing, and another finds the product better suited to hands-on practitioners than to GRC teams.

Pricing: quote-based, scaling with workloads (VMs, containers, serverless functions, managed services). It is listed on AWS Marketplace.

11. Orca Security

Orca scans agentlessly through SideScanning, which reads cloud APIs and block-storage snapshots. An optional lightweight eBPF sensor adds runtime detection on Kubernetes, VMs and ECS clusters.

Strengths

• ✓It maps findings to NIST SP 800-53, NIST CSF, DISA STIG, ISO 27001, PCI DSS, HIPAA, SOC 2, GDPR and FedRAMP, which suits regulated fintech and healthcare teams.
• ✓Its CDR ingests GuardDuty events and supports isolating workloads, revoking IAM credentials and rotating keys.
• ✓It connects to Jira, ServiceNow, Azure DevOps, GitHub and GitLab.

Limitations

• ✗One reviewer reports strong EC2 visibility but says alerting is too noisy for EKS workloads.
• ✗Reviewers say compliance framework customization needs work, and the sensor cannot run on Fargate or GKE Autopilot.

Pricing: custom quote through private offers on AWS Marketplace and Azure Marketplace.

12. Microsoft Defender for Cloud

Defender for Cloud provides CSPM, workload protection, attack-path analysis and workflow automation across Azure, AWS, GCP and on-premises environments.

Strengths

• ✓It gives Azure-first organizations one posture and workload view that includes their AWS accounts.

Limitations

• ✗It is optimized for Azure, so AWS-heavy teams should test EKS and IAM depth before choosing it over an AWS-focused platform.

13. Prowler

Prowler is an open-source security assessment tool and an AWS partner integration for adding security checks to pipelines and automation.

Strengths

• ✓It is the cheapest way for startups and cost-conscious teams to add repeatable AWS checks to CI/CD.

Limitations

• ✗You run and maintain the open-source edition yourself, and it assesses configuration rather than detecting threats at runtime.

14. Aqua Security

Aqua Security is a container security vendor listed among the partner tools that support pipeline security and automation with Security Hub.

Strengths

• ✓It suits container-centric teams that want image and pipeline controls feeding Security Hub.

Limitations

• ✗Public pricing and EKS and ECS coverage details were not verifiable for this guide, so validate both in a proof of value.

15. Splunk Enterprise Security

Splunk Enterprise Security is a SIEM with a native Security Hub integration, and Splunk Phantom covers the SOAR side.

Strengths

• ✓It suits enterprise SOCs that must correlate AWS findings with endpoint, network and identity-provider logs.

Limitations

• ✗It correlates findings but does not generate cloud posture or vulnerability context.
• ✗Cost grows with every CloudTrail and finding stream you forward.

Native vs third-party: overlap, decision rules and a baseline stack

Native AWS services are enough for a single-cloud estate with few accounts and light Kubernetes use. Teams outgrow them once they need runtime evidence, cross-cloud coverage or attack-path context to decide what to fix first.

Decision rules

• Stay native if you run one cloud, a handful of accounts and little Kubernetes, and your team clears the CVE queue each sprint.
• Add a CNAPP when Inspector findings outpace patching. Reachability and loaded-package filtering is the biggest noise reducer native tools lack.
• Choose a runtime-capable platform if EKS on EC2 nodes is central. On Fargate, every vendor here loses sensor coverage, so lean on GuardDuty and posture checks there.
• Prioritize CIEM depth if identity is your main attack surface. For example, a CI role unused for 120 days that still holds iam:PassRole and lambda:CreateFunction can create a Lambda function running as an admin role. Only graph-based tools flag that toxic combination in context, because they evaluate the role’s identity policy against SCPs, permission boundaries and the trust policy of the role it can pass.
• Add a SIEM only when you must correlate AWS with non-cloud telemetry, not to duplicate CNAPP alerting.

How to build a baseline AWS security stack

1. Enable GuardDuty, Security Hub, Config and Inspector across the AWS Organization from a delegated administrator account, so new accounts inherit the baseline automatically.
2. Turn on AWS Foundational Security Best Practices and CIS AWS Foundations Benchmark, then add PCI DSS or NIST SP 800-53 if you are regulated.
3. Enable Macie on buckets that hold customer data, and review Security Hub unused-access findings for IAM.
4. Route findings through an EventBridge rule that matches source aws.securityhub and detail-type Security Hub Findings, Imported, filter on CRITICAL and HIGH severity labels, and send the result to one ticketing or SOAR tool. Write suppression rules for approved patterns.
5. Add a third-party platform for the gaps that remain (runtime, attack paths, multi-cloud), then turn off duplicate ingestion.

Where Upwind fits in an AWS security stack

Upwind is a runtime-first CNAPP that pairs read-only, agentless cloud discovery with lightweight eBPF sensors on EC2 and EKS. It ranks CVEs by whether the vulnerable package is loaded, reachable and internet-exposed, and it correlates kernel-level telemetry with IAM actions and configuration into Threat Stories that include a timeline, root cause and response steps. It integrates with the AWS Security Hub extended plan and is listed on AWS Marketplace. As of October 2026, Upwind holds 4.8/5 from 88 reviews on Gartner Peer Insights, where users praise its runtime visibility and lower alert noise. A few reviewers note it is still maturing compared with larger, longer-established CNAPP vendors.

• ✓Covers EKS for Linux and Windows Server containers.
• ✓Combines CSPM, CWPP, CIEM, KSPM, API security, DSPM and CDR in one platform.
• ✓Uses CIEM to find over-permissioned roles, unused permissions and toxic combinations.
• ✓Includes Agentic Pack AI agents that investigate threats, validate exposure and generate fixes.

Which AWS security tools to choose by team size and maturity

The right AWS security stack depends on cloud footprint and team capacity. Start native, then add one third-party platform where native signals stop answering “what do we fix first?”

Native services have become strong signal generators, and Security Hub now covers unused IAM access. Third-party platforms compete on context, meaning reachability, effective permissions and runtime behavior. The best AWS security tools for your team are the smallest set that gives each finding exactly one owner, one priority and one fix path.
