Prowler vs Kloudle: 572 Checks vs 1,890 Checks

Why Teams Compare Prowler and Kloudle

Prowler is the most popular open-source cloud security scanner. It’s free, well-maintained, and has strong AWS coverage. Teams evaluating CSPM tools almost always look at Prowler first.

Kloudle is a commercial CSPM with a sovereign deployment option. It covers more providers, runs more checks, and includes a management UI — at a fixed $5K/year regardless of resource count.

This comparison helps you decide which fits your team.

Check Coverage

The most concrete difference: Kloudle runs 1,890 checks across five providers. Prowler runs 572 checks across three.

Provider	Prowler	Kloudle
AWS	~400	700+
GCP	~100	500+
Azure	~70	400+
DigitalOcean	0	150+
Kubernetes	0	140+
Total	~572	1,890

Prowler’s heritage is AWS — it started as an AWS-only tool and expanded to GCP/Azure later. That AWS-first DNA shows in coverage depth. GCP and Azure checks are significantly fewer and less detailed.

Kloudle was built multi-cloud from day one. Every provider has deep service coverage because the check library was designed to be provider-agnostic from the start.

Deployment Model

Prowler

Prowler is a CLI tool. You install it, configure credentials, run prowler aws or prowler gcp, and get a report. For scheduled scanning, you set up a cron job, Lambda function, or CI/CD step yourself.

Prowler also has a SaaS product (Prowler Cloud) with a UI, scheduled scans, and team management. The SaaS version uses per-resource pricing.

Kloudle

Kloudle offers two deployment options:

1. SaaS — hosted by Kloudle, quick setup, no infrastructure to manage
2. Sovereign — deploy on your infrastructure (VM + PostgreSQL). Scans execute from your network. Results never leave your environment.

The sovereign option gives you Prowler’s self-hosted benefit (data stays in your network) with Kloudle’s full feature set (UI, scheduling, team management, compliance reports).

Compliance Frameworks

Framework	Prowler	Kloudle
CIS Benchmarks	Yes (AWS, GCP, Azure)	Yes (all providers)
SOC 2	Yes	Yes
HIPAA	Yes	Yes
PCI DSS	Yes	Yes
ISO 27001	Yes	Yes
GDPR	Partial	Yes
NIS2	No	Yes
Custom policies	Python scripts	Configuration-based

Both tools cover the major compliance frameworks. Kloudle includes NIS2 (relevant for EU teams subject to the 2024 directive) and GDPR-specific data residency checks.

User Interface

Prowler CLI generates HTML, JSON, and CSV reports. They’re useful for point-in-time audits but don’t support team collaboration, trending, or drill-downs.

Prowler Cloud (SaaS) adds a dashboard, historical tracking, and team features. It’s a separate product with separate pricing.

Kloudle includes a full management UI in both SaaS and sovereign deployments: dashboard, finding details, remediation guidance, trend graphs, team roles, and compliance report generation.

AI Agent Integration

Kloudle provides an MCP server that AI agents can use to trigger scans, query findings, and check compliance status programmatically. This is relevant for teams building AI-powered security workflows.

Prowler has no native AI agent integration. You can script around the CLI, but there’s no structured protocol for agent interaction.

Pricing

	Prowler OSS	Prowler Cloud	Kloudle
Model	Free	Per-resource	Fixed annual
Cost at 100 resources	$0	~$1,200/yr	$5,000/yr
Cost at 1,000 resources	$0	~$12,000/yr	$5,000/yr
Cost at 10,000 resources	$0	~$50,000+/yr	$5,000/yr
UI included	No	Yes	Yes
Sovereign option	DIY	No	Yes

Prowler OSS is free but requires you to build and maintain the scheduling, storage, and UI layers. Prowler Cloud charges per resource — costs grow linearly with your infrastructure.

Kloudle’s fixed pricing means your bill doesn’t change as you scale. At ~1,000+ resources, Kloudle is cheaper than Prowler Cloud while including the sovereign deployment option.

Verdict

Choose Prowler OSS if:

• You only scan AWS
• You’re comfortable with CLI-only workflows
• You have engineering capacity to build automation around it
• Budget is zero

Choose Kloudle if:

• You scan multiple cloud providers (especially GCP, Azure, DigitalOcean, or Kubernetes)
• You need a UI for your security team
• You want sovereign deployment (data stays in your network)
• You want predictable costs that don’t scale with resource count
• You’re building AI agent workflows that need CSPM integration
