What is Sovereign CSPM? Self-Hosted Cloud Security Explained

Sovereign CSPM runs on your infrastructure — scans execute from your VMs, results stay in your database, and no cloud inventory data leaves your network.

What is Sovereign CSPM?

Sovereign CSPM is cloud security posture management that runs entirely on your infrastructure. Unlike SaaS CSPM tools that pull your cloud inventory data to their servers for analysis, sovereign CSPM executes scans from your VMs, stores results in your database, and generates compliance reports from your systems of record.

No cloud configuration data, no resource inventories, no security findings leave your network.

Why Sovereignty Matters

Traditional CSPM creates a paradox: to check whether your cloud is secure, you send a complete inventory of your infrastructure — every resource, every configuration, every IAM policy — to a third-party vendor’s cloud account.

This matters for three reasons:

1. Data Residency and Compliance

Regulations like GDPR, NIS2, and sector-specific rules (DORA for finance, HDS for healthcare in France) increasingly restrict where security-sensitive data can be processed. Your cloud inventory is security-sensitive data — it’s a blueprint of your attack surface.

2. Supply Chain Risk

When your CSPM vendor is breached, the attacker gets a detailed map of your infrastructure. This has happened — SolarWinds, Codecov, and other supply chain attacks demonstrated that security vendors are high-value targets precisely because they hold customer infrastructure data.

3. Audit and Evidence

For ISO 27001, SOC 2, and FedRAMP audits, you need to demonstrate control over your security tooling chain. “A third party holds our security findings” creates audit questions. “We run scanning on our infrastructure and control the entire evidence chain” does not.

How Sovereign CSPM Works

The architecture is straightforward:

  1. Deploy — Run the CSPM engine on a VM in your cloud account (or on-premise)
  2. Configure — Grant read-only access to your cloud accounts (same as any CSPM)
  3. Scan — The engine queries cloud APIs from within your network
  4. Store — Results are written to your PostgreSQL database
  5. Report — Compliance reports are generated from your database
  6. Access — Your team accesses the dashboard on your network

The key difference from SaaS: steps 3-6 all happen inside your perimeter. The CSPM vendor provides the software; you provide the runtime.

Sovereign vs Self-Hosted vs On-Premise

These terms overlap but aren’t identical:

TermMeaning
Self-hostedYou run the software on your infrastructure. May still phone home for licensing, updates, or telemetry.
On-premiseSoftware runs in your data center. Often implies air-gapped or legacy deployment.
SovereignYou control the data, the runtime, and the evidence chain. No telemetry, no data exfiltration path, full audit trail under your control.

Sovereign is the strongest guarantee. Self-hosted is a deployment model. Sovereign is a data control model.

Who Needs Sovereign CSPM?

  • Regulated industries — Finance (NIS2, DORA), healthcare (HIPAA, HDS), government (FedRAMP, IL4+)
  • EU companies under GDPR with strict data residency interpretations
  • Security-conscious startups that don’t want to expand their vendor attack surface
  • Teams with air-gapped environments that can’t use SaaS tools
  • Organizations where the CISO requires full evidence chain control for audit
