Best Agentless Cloud Security Alternatives to Wiz in 2026

Agentless cloud security platforms provide visibility into cloud environments without deploying agents on individual workloads. These tools connect via cloud provider APIs or use out-of-band scanning

By use case

Organizations that want deep agentless scanning with strong vulnerability management and malware detection across multi-cloud environments

Orca Security

The closest agentless alternative to Wiz, using patented SideScanning technology that reads block storage out-of-band for deep workload visibility. Best for organizations that want agentless scanning with stronger vulnerability management and malware detection than Wiz provides.

Cloud
Organizations where cloud identity and access management risk is the primary security concern, especially those already using Tenable products

Ermetic

The deepest cloud identity security platform, now part of Tenable Cloud Security. Best for organizations where CIEM and cloud identity risk are the primary security concerns, offering automated least-privilege recommendations and just-in-time access provisioning.

Cloud
Organizations already invested in Check Point's network security stack that want unified cloud and network security management

Check Point CloudGuard

A solid agentless CSPM option backed by Check Point's decades of threat intelligence. Best for organizations already invested in the Check Point ecosystem that want unified cloud posture management alongside network security.

Frequently Asked Questions

Agentless platforms scan cloud environments periodically via APIs or snapshots, which means they cannot provide real-time runtime protection, detect in-memory threats, or block attacks as they happen. They excel at identifying misconfigurations, vulnerabilities, and posture issues but cannot stop a running exploit. Organizations with strict runtime security requirements often complement agentless platforms like Wiz with agent-based tools like Sysdig or Aqua Security for real-time detection and response.

Wiz connects via cloud provider APIs (AWS, Azure, GCP) to analyze cloud configuration data, container images, and resource metadata. Orca Security uses SideScanning technology that reads the actual block storage of running workloads out-of-band, providing deeper OS-level and application-level visibility. Wiz's API approach is faster to deploy and lighter-weight, while Orca's block storage scanning captures more detail at the workload level, including malware and deep vulnerability data.

Agentless cloud security platforms provide strong vulnerability detection for cloud workloads, but they are not a full replacement for traditional vulnerability management programs that cover on-premises servers, endpoints, and network devices. For cloud-only environments, platforms like Wiz and Orca provide comprehensive vulnerability visibility. For hybrid environments, you will still need a vulnerability management solution like Tenable or Qualys alongside your cloud security platform.

Agentless platforms like Wiz can be deployed in hours by connecting cloud account APIs. There are no agents to install, no network changes, and no maintenance overhead. Wiz typically provides initial findings within minutes of connecting a cloud account. Orca Security's SideScanning takes slightly longer for initial results as it reads block storage, but both platforms deliver dramatically faster time-to-value compared to agent-based solutions that require weeks of deployment planning.
