Wiz EU Alternative 2026: CLOUD Act & GDPR Risk in CNAPP Security

Post #4 in the sota.io EU Security Tools Series

Wiz has become the fastest-growing cloud security company in history — reaching $500 million ARR in record time and achieving a $12 billion valuation before Google (Alphabet Inc.) agreed to acquire it for $32 billion in 2025. For European security teams, Wiz's CNAPP (Cloud Native Application Protection Platform) is technically impressive: agentless scanning, deep cloud posture visibility, and a unified risk graph across AWS, Azure, GCP, and OCI. But the Google acquisition changes the GDPR calculus fundamentally.

Wiz, Inc. is a Delaware C-Corporation, and after the Google acquisition it sits inside one of the most prominent CLOUD Act targets in the world. This is the fourth post in our EU Security Tools Series — following our analyses of CrowdStrike, SentinelOne, and Palo Alto Networks.

Wiz Corporate Structure: The Google Factor

Wiz was founded in 2020 by Assaf Rappaport and team (former Microsoft engineers) and incorporated in Delaware. The Google acquisition — formally announced in 2025 — places Wiz directly under Alphabet Inc., itself a Delaware holding company subject to the CLOUD Act (18 U.S.C. §2713) and FISA 702 orders.

The parent structure matters enormously. Google has historically received more FISA 702 orders than almost any company in the world — documented in the PRISM program revelations and subsequent declassified FISA Court reports. When US law enforcement or intelligence agencies serve a CLOUD Act warrant on Google, Wiz data held in European data centers can be included in the scope.

CLOUD Act Exposure Analysis

The Clarifying Lawful Overseas Use of Data Act (CLOUD Act, 2018) allows US authorities to compel US-controlled service providers to produce data stored anywhere in the world. Three factors determine Wiz's exposure:

Factor 1: Delaware incorporation of Wiz, Inc. Any Delaware corporation is subject to US federal court jurisdiction. A CLOUD Act warrant served on Wiz, Inc. compels production of EU customer data regardless of where it is stored.

Factor 2: Alphabet Inc. as ultimate parent Even if Wiz were somehow argued to be outside direct CLOUD Act reach (it cannot), Alphabet Inc. is clearly subject to CLOUD Act. As a wholly-owned subsidiary, Wiz's data is attributable to Alphabet's custody and control under CLOUD Act doctrine (see United States v. Microsoft Corp., 584 U.S. 236 (2018) and subsequent CLOUD Act codification).

Factor 3: FISA 702 / Section 702 NSA Orders Alphabet/Google has consistently appeared on FISA 702 target lists disclosed post-Snowden. After the Google acquisition, Wiz's customer data — including cloud security telemetry, vulnerability scan results, and access patterns for EU customers' cloud environments — falls within Alphabet's FISA 702 data scope. This data is extraordinarily sensitive: it describes the complete security posture of EU customers' cloud infrastructure.

The combination of Wiz's agentless scanning (which produces detailed inventory of every resource, secret, and misconfiguration in a customer's cloud environment) and Google-level CLOUD Act/FISA 702 exposure creates a uniquely high-risk profile for EU organizations in regulated sectors.

GDPR Risk Matrix: Wiz Scores 21/25

Using the same methodology applied to other tools in this series:

Why data sensitivity scores 4/5: Wiz's agentless scans capture secrets, misconfigurations, network exposure, IAM relationships, and vulnerability data across an EU organization's entire cloud estate. If this data is disclosed via CLOUD Act warrant, it does not merely expose personal data — it exposes the complete attack surface of regulated financial, healthcare, or infrastructure organizations. This is categorically different from, say, a collaboration tool's data exposure.

What Wiz's EU Data Residency Does (and Does Not) Protect

Wiz offers European customers the ability to store scan results and platform data in EU data centers (Frankfurt, Dublin). This protects against:

• Routine data access by US employees without legal process
• Accidental data exposure across geographic regions
• Some categories of commercial data sharing

It does not protect against:

• CLOUD Act warrants served on Wiz, Inc. or Alphabet Inc.
• FISA 702 orders directed at Alphabet's communication systems
• National security letters (NSLs) — which come with gag orders preventing customer notification
• Bilateral data sharing under US-EU law enforcement cooperation agreements (MLAT)

The critical distinction: EU data residency is a data processing measure. CLOUD Act is a legal compulsion measure. These operate at different levels of the compliance stack, and the former cannot neutralize the latter.

NIS2 and DORA Implications

For EU organizations in critical sectors, two directives compound the Wiz risk:

NIS2 (Directive 2022/2555): NIS2 requires operators of essential services to conduct thorough ICT supply chain risk assessments. A CSPM/CNAPP vendor with CLOUD Act exposure and access to complete cloud infrastructure posture data qualifies as a high-risk ICT third party. Security teams should document the risk explicitly in their NIS2 supply chain registers.

DORA (Regulation 2022/2554): Financial entities under DORA must perform enhanced due diligence on ICT critical third-party service providers (CTPPs). Given that Wiz scans financial entities' cloud environments — capturing configuration data for payment systems, core banking infrastructure, and customer data environments — the Google/Wiz combination presents exactly the type of concentration risk DORA was designed to address. The EBA, EIOPA, and ESMA have signaled that CLOUD Act exposure is a material factor in CTPP assessments.

EU-Native Alternatives to Wiz

The EU CNAPP/CSPM market is less mature than the US market, but genuine EU-native options exist:

1. Cyscale — Romania (EU-Native CSPM)

Founded: 2019 in Cluj-Napoca, Romania Jurisdiction: Romanian law, EU data protection regime GDPR Risk Score: 4/25 (EU-native, no US parent)

Cyscale is the most direct EU-native replacement for Wiz's CSPM capabilities. It provides:

• Agentless cloud security posture management across AWS, Azure, GCP, and Alibaba Cloud
• 400+ security controls mapped to CIS Benchmarks, ISO 27001, SOC 2, GDPR, and NIS2
• Identity and access management (IAM/CIEM) analysis
• Real-time misconfiguration detection and remediation workflows

Cyscale's investor base is European (EU VC firms), its data is processed in EU data centers, and it operates under Romanian law — an EU member state with full GDPR applicability. For organizations that need Wiz-class CSPM without US CLOUD Act exposure, Cyscale is the primary EU-native option.

Limitation vs Wiz: Cyscale's risk graph and CWPP (workload protection) capabilities are less mature than Wiz's. It excels at CSPM but does not yet match Wiz's depth in container security or code-to-cloud tracing.

2. TEHTRIS — France (XDR with Cloud Security)

Founded: 2010 in Pessac (Bordeaux), France Jurisdiction: French law (S.A.S.), EU data sovereignty GDPR Risk Score: 3/25

TEHTRIS provides a comprehensive XDR platform that includes cloud workload protection and cloud threat detection alongside endpoint, network, and identity security. As a French company certified by ANSSI (Agence nationale de la sécurité des systèmes d'information), TEHTRIS operates under French jurisdiction with no US parent.

TEHTRIS Cloud Capabilities:

• Cloud workload protection (CWPP) for AWS, Azure, and GCP workloads
• Anomaly detection in cloud environments via behavioral AI
• Integration with cloud-native logging (CloudTrail, Azure Monitor, GCP Audit Logs)
• Threat intelligence fed from the European threat landscape

TEHTRIS is suitable for organizations that need broader XDR coverage (endpoint + cloud + network) in a single EU-native platform, though it does not provide the deep CSPM posture scanning that Wiz or Cyscale offer.

3. Sekoia.io — France (SOC Platform with Cloud Detection)

Founded: 2017 in Paris, France Jurisdiction: French SAS, EU data sovereignty GDPR Risk Score: 3/25

Sekoia.io is a European SOC platform combining SIEM, SOAR, and threat intelligence with strong cloud detection capabilities. While not a direct Wiz replacement (Wiz is proactive CNAPP; Sekoia is reactive SOC), many EU organizations use Sekoia.io to detect misconfigurations and cloud threats through log ingestion rather than agentless scanning.

Sekoia.io for Cloud Security:

• Ingest CloudTrail, Azure Sentinel feeds, GCP audit logs
• 400+ built-in detection rules mapped to MITRE ATT&CK Cloud matrix
• Playbook automation for cloud incident response
• EU Threat Intelligence feeds from CERT-FR and ENISA

Sekoia.io pairs well with Cyscale: Cyscale handles posture management, Sekoia.io handles detection and response — achieving full CNAPP coverage with two EU-native vendors.

4. Open-Source Self-Hosted Stack (No US Jurisdiction)

For organizations that require guaranteed data sovereignty without any US vendor dependency, an open-source self-hosted CNAPP stack eliminates CLOUD Act exposure entirely:

Running this stack on EU-sovereign infrastructure (Hetzner, OVHcloud, Deutsche Telekom T-Systems) with EU-based teams provides CNAPP capabilities with zero US jurisdiction exposure. The trade-off is operational complexity — this stack requires dedicated security engineering to maintain, tune, and operate.

Migration Strategy: From Wiz to EU-Native CNAPP

Migrating from Wiz requires a phased approach because Wiz's agentless scans produce a risk graph that teams rely on for daily operations:

Phase 1 — Inventory & Gap Analysis (Weeks 1-4) Deploy Cyscale in parallel with Wiz. Map Wiz's top-priority findings to Cyscale's control library. Identify gaps in coverage (particularly in CWPP and code-to-cloud tracing).

Phase 2 — Detection Layer Migration (Weeks 5-8) Deploy Sekoia.io and configure cloud log ingestion. Migrate cloud-specific SIEM rules from existing tooling. Validate detection coverage against Wiz's cloud detection capabilities.

Phase 3 — Wiz Decommission (Weeks 9-12) Once Cyscale + Sekoia.io provide equivalent visibility for your compliance frameworks (CIS, ISO 27001, NIS2, DORA), begin decommissioning Wiz. Remove Wiz's cloud connector credentials and verify no data remains in Wiz/Google systems.

Phase 4 — Compliance Documentation Update your NIS2 ICT supply chain register and DORA CTPP assessments to reflect the transition. Document the reduction in CLOUD Act exposure for DPA (Data Protection Authority) reporting purposes.

Cost Comparison

Wiz's pricing has increased significantly following the Google acquisition as the integration into Google Cloud Security brings premium positioning. EU-native alternatives typically deliver 40–60% cost savings for equivalent CSPM/CNAPP coverage.

Summary

Wiz is a technically excellent CNAPP platform. But following its acquisition by Google (Alphabet), it carries the maximum possible CLOUD Act and FISA 702 exposure of any cloud security vendor — because its parent is one of the most prominent targets of US intelligence collection programs. For EU organizations in financial services, healthcare, critical infrastructure, or any NIS2/DORA-regulated sector, this exposure is not theoretical: it is a documented, compelled-access risk.

The EU-native alternatives — Cyscale for CSPM, TEHTRIS for XDR, Sekoia.io for detection — do not yet match Wiz feature-for-feature. But the combination of Cyscale + Sekoia.io delivers full CNAPP coverage (posture + detection) under EU jurisdiction, at significantly lower cost, and without the CLOUD Act risk that Wiz's Google ownership now guarantees.

EU security teams conducting vendor risk assessments should score Wiz at 21/25 on GDPR Risk — the same as CrowdStrike, SentinelOne, and Palo Alto Networks — and evaluate EU-native alternatives as part of their NIS2 supply chain due diligence.
