Cloud Vulnerability Management -- Tenable Alternatives

Best Tenable Alternatives for Cloud Vulnerability Management in 2026

Cloud vulnerability management addresses the unique challenges of securing cloud-native assets across AWS, Azure, GCP, and multi-cloud environments. Unlike traditional on-premises scanning, cloud VM requires API-based asset discovery, cloud workload assessment, infrastructure-as-code scanning, container security, and cloud security posture management (CSPM). These Tenable alternatives offer different approaches to cloud vulnerability management, from agent-based endpoint scanning to cloud-native security platforms.

How It Works

1

Connect Cloud Platform APIs for Asset Discovery

Configure API connections to AWS, Azure, and GCP to automatically discover cloud assets including EC2 instances, virtual machines, containers, serverless functions, managed databases, and storage buckets. Cloud APIs provide real-time inventory that captures ephemeral assets traditional scanning would miss.

2

Deploy Cloud Workload Scanning

Install lightweight scanning agents on cloud workloads (EC2, Azure VMs, GKE nodes) for authenticated vulnerability assessment. Use agentless snapshot-based scanning for workloads where agent deployment is impractical. Configure container image scanning in your registry and CI/CD pipeline to catch vulnerabilities before deployment.

3

Assess Cloud Infrastructure Configuration

Scan cloud infrastructure configurations for security misconfigurations — publicly exposed storage buckets, overly permissive IAM policies, unencrypted databases, disabled logging, and network security group gaps. Use cloud security posture management (CSPM) capabilities to assess against CIS Cloud Benchmarks for AWS, Azure, and GCP.

4

Integrate with Infrastructure-as-Code Pipelines

Shift vulnerability and misconfiguration scanning left by integrating into Terraform, CloudFormation, and Kubernetes manifest pipelines. Scan IaC templates before deployment to prevent vulnerable or misconfigured infrastructure from reaching production. Use tools like Nuclei or Tenable.cs to automate pre-deployment security checks.

5

Monitor and Remediate Cloud Vulnerabilities Continuously

Establish continuous monitoring for cloud vulnerability posture with automated alerting for critical findings. Leverage cloud-native remediation — auto-patching through SSM/Intune, infrastructure redeployment through IaC pipelines, and container image rebuilds for vulnerable base images. Track cloud vulnerability metrics separately from on-premises to account for the dynamic nature of cloud environments.

Cloud Vulnerability Management FAQ

How does cloud vulnerability management differ from traditional VM?

Cloud VM must account for ephemeral assets that traditional scanners miss (auto-scaled instances, containers, serverless functions), cloud-specific misconfigurations (IAM policies, storage permissions, network rules), shared responsibility boundaries, and infrastructure-as-code pipelines. Traditional network scanning cannot assess cloud configurations — API-based assessment and cloud-native connectors are required. Additionally, cloud remediation often involves redeploying infrastructure rather than patching in place.

Does Tenable support cloud vulnerability management?

Yes. Tenable provides cloud vulnerability management through Tenable.io cloud connectors for AWS, Azure, and GCP asset discovery, Tenable.cs for container and infrastructure-as-code scanning, and Nessus agents for cloud workload assessment. Tenable One provides unified exposure management across cloud and on-premises environments. However, Tenable's cloud capabilities are less mature than cloud-native CSPM platforms, and organizations with complex multi-cloud environments may supplement Tenable with dedicated cloud security tools.

Should I use a dedicated cloud security platform or extend my VM tool to the cloud?

For basic cloud workload vulnerability scanning, extending your existing VM tool (Tenable, Qualys, Rapid7) to the cloud is sufficient and simplifies reporting. For comprehensive cloud security including CSPM, CWPP, CIEM, and IaC scanning, dedicated cloud security platforms like Wiz, Orca, or Prisma Cloud provide deeper cloud-native capabilities. Many enterprises use both — their traditional VM tool for workload scanning and a cloud-native platform for configuration and identity security.

How do I scan containers for vulnerabilities?

Container vulnerability scanning should occur at multiple stages: in the CI/CD pipeline during image build, in the container registry before deployment, and at runtime in the cluster. Tenable.cs, Qualys Container Security, and Nuclei all provide container image scanning. For runtime container protection, CrowdStrike and Qualys offer runtime vulnerability assessment. Prioritize scanning in the CI/CD pipeline to prevent vulnerable images from ever reaching production.
