Prowler vs Wiz: Open Cloud Security Platform vs Closed, Provider Owned Security Platform

The Fundamental Difference: Open vs Closed

Prowler and Wiz take fundamentally different approaches to cloud security. Prowler is an open cloud security platform built on an Apache 2.0 licensed codebase with 14,000+ GitHub stars and 300+ contributors. Every check, every detection rule, every compliance mapping is inspectable, auditable, and modifiable. Your security team can read the exact code that protects your infrastructure.

Wiz is a proprietary, closed-source detection engine. You cannot inspect how Wiz determines a finding. You cannot modify checks to match your organization's specific security posture requirements. You cannot audit the logic behind a compliance result. You accept whatever the vendor ships.

This matters practically. When a compliance auditor asks "how does your tool determine this finding?", Prowler users can point to the exact Python class and its execute() method. Wiz users can point to a PDF. When your security team disagrees with a detection rule's logic, Prowler users can fork it. Wiz users submit a feature request and wait.

Prowler was created in 2016 by Toni de la Fuente, a former AWS security engineer who understood that cloud security tooling needs to be transparent, auditable, and vendor-neutral. That philosophy is baked into the architecture. Organizations like Salesforce, Siemens, Tesla, and IBM trust Prowler, as do over 300 contributors who have battle-tested the codebase across thousands of real-world environments.

Cost Comparison: Prowler Is 10x Less Expensive

Prowler Cloud uses per-account pricing. Wiz charges per workload. That structural difference means Prowler costs a fraction of Wiz at every scale, and the gap widens as your environment grows.

Why Prowler's pricing model is structurally cheaper

• Per-account pricing means your cost scales with your organizational structure, not with the number of EC2 instances, Lambda functions, or S3 buckets you run.
• No per-user fees. Your entire security team, DevOps team, and compliance team can all access the platform without additional charges.
• No module upselling. You do not pay extra for compliance frameworks, IaC scanning, or Kubernetes support.
• The open source foundation means R&D costs are shared with a global community. That efficiency gets passed to customers.
• The open source CLI is completely free. No workload limits, no feature gates, no time-limited trials.

Customization and AI-Native Extensibility

Prowler is built to be extended. Every security check is a Python class with a metadata YAML file. Any security engineer can write a custom check in under an hour. That extensibility is not a future promise: organizations like Inditex (the parent company of Zara), Spain's National Cryptologic Center (CCN), and AWS have contributed extensions to the platform.

Available today

• Custom checks via Python: inherit from the Check base class, implement execute(), return CheckReport objects. Standard pattern, well-documented, battle-tested.
• Prowler Studio: AI assistant that helps create threat detection checks, generate remediations, and update compliance frameworks.
• Prowler MCP Server (mcp.prowler.com/mcp): Exposes Prowler's capabilities to any MCP-compatible AI agent. Security teams can build agentic workflows where Claude Code, Cursor, or other AI tools query findings, trigger scans, and correlate results.
• Custom compliance frameworks: map any regulatory requirement to Prowler checks using YAML configuration. Model your internal security policies as a trackable framework.
• Extensible plugin architecture: proven pattern for adding entirely new cloud provider support.

Architecture direction (roadmap)

Prowler's extensible plugin architecture is designed so that new cloud provider support can be added dynamically. The goal: enable AI harnesses (Claude Code, Cursor, Gemini Code Assist, or any MCP-compatible agent) to analyze a cloud provider's API documentation, generate the service client and corresponding security checks, and submit them for review. When Prowler added Cloudflare support, it shipped with 29 checks covering DNS, SSL/TLS, WAF, access control, and zone configuration. That same pattern is replicable for any cloud service with a well-documented API.

Choose the AI Model That Powers Your Security

Most platforms hand you one AI assistant running one model, take it or leave it, on the vendor's infrastructure. Prowler lets you choose the model behind your AI security workflows. That matters for two reasons: performance, and keeping your data inside your own boundary.

• Best-in-class by default. Your Prowler license includes the top-performing model from OpenAI, so you get state-of-the-art AI out of the box with nothing to set up.
• Bring your own model from Amazon Bedrock. Prefer a different model, or need every prompt and response to stay inside your perimeter? Point Prowler at Amazon Bedrock and run the entire AI workflow within your own security boundary. Your data does not leave your environment. That is a hard requirement for regulated and security-conscious teams, and it is a choice Wiz does not give you.
• Bring a custom or OpenAI-compatible model via OpenRouter. Run your own fine-tuned model, or any OpenAI-compatible model available through OpenRouter. You are never locked into one vendor's idea of which AI you should use.

Coverage and CI/CD: Open Connectors, Pipeline-Native

Both Prowler and Wiz cover a broad set of clouds and SaaS platforms, so this is not a contest about a raw provider count. Wiz supports AWS, Azure, GCP, OCI, Alibaba Cloud, Cloudflare, Vercel, VMware, Kubernetes, Microsoft 365, Okta, GitHub, GitLab, and more. The real differences are that every Prowler connector is open source and inspectable, and that Prowler runs natively in any CI/CD pipeline while Wiz's pipeline coverage is essentially HCP Terraform.

Prowler coverage depth (16 providers, all open source)

• AWS: The deepest coverage of any open source tool. Hundreds of checks across 60+ services. Official AWS Security Hub partner integration (AWS recommends Prowler per the AWS Security Blog). Supports AWS European Sovereign Cloud.
• Azure: Full CIS Benchmark coverage including Entra ID (formerly Azure AD) MFA checks. Includes Bicep remediation code.
• GCP: CIS Benchmark coverage with Cloud Asset Inventory integration.
• Kubernetes: CIS Kubernetes Benchmark with cluster-level and namespace-level security checks.
• Microsoft 365: Powered by a custom hybrid architecture using Microsoft Graph API and controlled PowerShell sessions (py-pwsh-session, open sourced by Prowler).
• GitHub and Okta: Repository, organization, and identity security configuration checks.
• Cloudflare: 29 checks covering DNS, SSL/TLS, WAF, access control, and zone configuration.
• Plus: Google Workspace, MongoDB Atlas, Alibaba Cloud, Oracle Cloud, OpenStack, Vercel, and more.
• Infrastructure as Code: Terraform and CloudFormation scanning via Trivy integration.

CI/CD is where the gap is real

Prowler is a CLI and container, so it drops into any pipeline you already run. It ships an official GitHub Action and documented GitLab CI support, and it runs anywhere you can run a command or a container: Jenkins, Azure DevOps, CircleCI, AWS CodeBuild, Bitbucket Pipelines, and more. You can fail a build on a policy violation and catch misconfigurations before they ever reach production.

Wiz's CI/CD story is much narrower. On its own supported-environments list, the entire CI/CD category is HCP Terraform. If you want security checks running across your real pipeline estate, that is a meaningful difference, and because Prowler is open source you can wire it into custom or in-house pipelines that no vendor would build a connector for.

Compliance Framework Coverage: 70+ Frameworks

Prowler maps findings to over 70 compliance frameworks. This is where Prowler's depth is unmatched. Wiz supports an estimated 40 frameworks (Wiz does not publicly document the exact count).

Industry standards

CIS Benchmarks (multiple versions including 2.0, 2.1, 3.0, 4.0), NIST 800-53 (Rev. 4 and Rev. 5), NIST Cybersecurity Framework (CSF), CISA Cyber Essentials, MITRE ATT&CK.

Regulatory

RBI (Reserve Bank of India), FedRAMP (Moderate and High), PCI-DSS (v3.2.1 and v4.0), NIS2.

Privacy and data protection

GDPR, HIPAA, FFIEC.

Governance

SOC 2 (Type II), GXP, ISO 27001.

Cloud-native

AWS Foundational Technical Review (FTR), AWS Well-Architected Framework (Security Pillar), BSI C5.

National security

ENS (Spain's Esquema Nacional de Seguridad), KISA ISMS-P (Korean). These regional frameworks exist in Prowler because the open source community contributed them. No other CNAPP has Korean frameworks. This is the power of an open source community: contributors build what they actually need.

Custom frameworks

Build any framework by mapping your internal security requirements to Prowler checks via YAML. Model your company's security policies as a compliance framework, track adherence automatically, and export audit-ready reports. This is unique to Prowler.

Trust and Independence

Your security tool should not be owned by a cloud provider that competes with the infrastructure you are securing. After Google completed its $32 billion acquisition of Wiz on March 11, 2026, this is exactly the situation Wiz customers face.

Google says Wiz will remain multi-cloud. But no contractual guarantee of perpetual multi-cloud support exists. Multiple industry analysts have raised concerns:

• Forrester VP Merritt Maxim called Wiz a potential "Trojan horse" for Google Cloud workload migration.
• Deepwatch PM Kaushik Devireddy raised concerns about whether cloud-equality will hold up under Google ownership.
• Sysdig CFO Karen Walker noted Wiz customer concerns about the acquisition's impact.

Prowler is independently owned and open source. The community, including contributions from organizations like AWS, Inditex, and Spain's CCN, ensures the platform evolves based on real-world security needs, not a cloud vendor's commercial incentives.

AWS itself trusts Prowler: native Security Hub partner integration, AWS Security Blog guides on using Prowler, and explicit recommendations to customers. Prowler is also a CIS Security partner (listed on cisecurity.org). Prowler Cloud is SOC 2 Type 2 compliant. These are third-party validations that cannot be bought with acquisition dollars.

Attack Paths and Risk Prioritization

Both Prowler and Wiz offer attack path analysis. They take different architectural approaches.

Prowler ThreatScore provides weighted risk prioritization that considers severity, context, and impact to help teams focus on what matters first. Prowler's approach is open and extensible. Wiz's approach is more polished in its current UX. Both get you to attack path visibility, but only Prowler lets you customize and extend the analysis.

Integration into Agentic AI and MSSP Workflows

Prowler is built for the way modern security operations are headed: AI-assisted, automated, and API-first.

• Prowler MCP Server: Any MCP-compatible AI agent (Claude Code, Cursor, or any tool that speaks MCP) can query findings, trigger scans, and correlate results. Security operations can be automated with agentic workflows.
• OCSF-native output: Prowler findings use the Open Cybersecurity Schema Framework, making them immediately consumable by any SIEM, SOAR, or data platform that supports OCSF.
• MSSP-friendly architecture: The open source license and per-account pricing let MSSPs build profitable managed services without per-seat licensing eating margins. Custom checks, white-label reporting, and multi-tenant scanning are all supported.
• CI/CD integration: Run Prowler in GitHub Actions, GitLab CI, Jenkins, or any pipeline. Block deployments that fail security checks.

Wiz has an MCP server available on AWS Marketplace, and it integrates with CI/CD pipelines. But the underlying platform is closed. You can query Wiz findings via MCP, but you cannot extend the detection logic, add custom checks through the MCP interface, or build new provider support. For MSSPs, Wiz's per-workload pricing and closed architecture make it harder to build differentiated, cost-effective managed services.
