EOR Provider Security: SOC 2, ISO 27001, and What to Verify

Your EOR Provider Holds Your Employees’ Most Sensitive Data

Passport numbers. Bank account details. Tax IDs. Salary data. Health insurance enrollments. Home addresses. Social security numbers. An EOR provider’s database is, from a cybersecurity perspective, one of the highest-value targets in the HR technology stack. A breach doesn’t just expose your company — it exposes your employees’ most personal information across multiple jurisdictions, each with its own breach notification requirements and penalties.

If this post changes your vendor shortlist, validate it against head-to-head comparisons, implementation guidance, and country-level hiring demand.

Yet when most companies evaluate EOR providers, security gets a single checkbox on the procurement scorecard: “Do they have SOC 2?” That’s the wrong question. The right questions are: What type of SOC 2? What’s in scope? When was the last audit? And what else do they have beyond SOC 2?

SOC 2: What It Actually Means

SOC 2 (Service Organization Control 2) is an auditing framework developed by the AICPA that evaluates a service provider’s controls across five Trust Services Criteria: security, availability, processing integrity, confidentiality, and privacy. Most EOR providers pursue SOC 2 with security as the primary criterion, sometimes adding availability and confidentiality.

Type I vs. Type II — the distinction that matters. SOC 2 Type I evaluates whether controls are properly designed at a specific point in time. SOC 2 Type II evaluates whether those controls operated effectively over a period (typically 6–12 months). Type I is a snapshot. Type II is a track record. If your EOR provider only has Type I, they’ve demonstrated they have the right policies on paper. If they have Type II, they’ve demonstrated those policies actually worked over a sustained period.

Enterprise procurement teams should require SOC 2 Type II. A Type I report from two years ago with no Type II follow-up is a warning sign — it suggests the provider invested in the initial certification but hasn’t maintained the ongoing audit discipline.

What’s in scope matters more than the certification itself. A SOC 2 report covers specific systems and processes. An EOR provider might have SOC 2 for its platform infrastructure but not for its local payroll processing operations. If the certification covers the SaaS platform but not the backend systems that handle payroll data in 30 countries, the protection gap is significant. Ask for the scope description from the audit report.

ISO 27001: The International Standard

ISO 27001 is an international standard for information security management systems (ISMS). Unlike SOC 2, which is an attestation by an external auditor, ISO 27001 is a certification granted by an accredited body after a comprehensive audit of the organization’s security management framework.

ISO 27001 covers:

Risk assessment and treatment methodology
Information security policies and procedures
Access control and identity management
Cryptographic controls
Physical and environmental security
Operations security (change management, malware protection, backup)
Communications security (network controls, information transfer)
Supplier relationship security
Incident management
Business continuity

For EOR providers operating across jurisdictions, ISO 27001 is arguably more relevant than SOC 2 because it addresses the entire security management system rather than specific controls. A provider with ISO 27001 has demonstrated that security governance permeates the organization, not just the engineering team.

Certification scope again matters. ISO 27001 can be scoped to specific business units or locations. An EOR provider might certify its headquarters operations without including its local entities in Brazil, India, or the Philippines. The local entities are where your employees’ data lives — verify that the certification covers the operations, not just the corporate office.

Provider Certification Landscape

Based on publicly available information and direct verification with provider security teams as of early 2026:

Provider	SOC 2 Type II	ISO 27001	Other notable certifications
Deel	Yes	Yes	GDPR compliance verified, CSA STAR
Remote	Yes	Yes	GDPR compliance verified
Rippling	Yes	Yes	SOC 1 Type II
Multiplier	Yes	In progress	GDPR compliance framework
Oyster	Yes	Yes	—
G-P	Yes	Yes	GDPR compliance verified
Papaya Global	Yes	Yes	SOC 1 Type II, PCI DSS
Pebl	Yes	Yes	—
Atlas HXM	Yes	In progress	—

Smaller and regional providers vary significantly. Some niche providers have no SOC 2 or ISO 27001 certification at all. This doesn’t automatically mean their security is poor, but it means you have no independent verification and your procurement team takes on more due diligence burden.

Beyond Certifications: What Enterprise Procurement Should Verify

Certifications are necessary but not sufficient. They tell you the provider meets a baseline standard. They don’t tell you how they handle the specific risks of an EOR operation. Here’s the deeper checklist:

Data encryption

In transit: TLS 1.2 or higher for all data transmission. TLS 1.3 preferred.
At rest: AES-256 encryption for stored data, including payroll records, identity documents, and employment contracts.
Key management: How are encryption keys stored and rotated? Hardware security modules (HSMs) or cloud KMS with automated rotation is the standard.

Access controls

Role-based access (RBAC): Who at the provider can access your employees’ data? Access should be limited to individuals who need it for specific processing tasks.
Privileged access management: How are admin accounts controlled? Multi-factor authentication (MFA) should be mandatory for all internal access. Privileged access should require approval workflows and time-limited sessions.
Customer access: Can you control which of your team members see which employees’ data? Larger EOR providers offer granular admin permissions. Smaller ones often have all-or-nothing access.
Audit logging: All access to employee data should be logged with timestamps, user identity, and action taken. Logs should be immutable and retained for at least 12 months.

Infrastructure security

Cloud provider: Which cloud infrastructure hosts the platform? AWS, GCP, and Azure all have robust security programs. Ask about the specific services used and whether the provider leverages cloud-native security controls (VPCs, security groups, encryption at rest by default).
Penetration testing: Conducted by an independent firm at least annually. Ask for the date of the most recent test and whether critical findings were remediated.
Vulnerability management: Automated scanning frequency (at least weekly), patch management timelines (critical vulnerabilities patched within 24–48 hours), and dependency management for third-party libraries.

Incident response

Response plan: Documented, tested, and updated at least annually. Should include client notification procedures, forensic investigation processes, and regulatory reporting workflows.
Breach history: Has the provider experienced a data breach? If yes, how was it handled, and what changes were made afterward? Honest disclosure of past incidents is a better indicator of security maturity than a claim of zero incidents.
Notification timeline: How quickly will the provider notify you of a security incident? GDPR requires notification within 72 hours — your provider should commit to notifying you within 24–48 hours so you have time to meet your own regulatory deadlines.

Sub-processor security

Your EOR provider doesn’t operate in isolation. They use local payroll processors, banking partners, benefits providers, and cloud services. Each sub-processor that touches employee data is a potential vulnerability.

Sub-processor list: Request a current list of all sub-processors that access employee personal data, including their locations and the data they handle.
Sub-processor due diligence: How does the provider evaluate sub-processor security? Do they require SOC 2 or equivalent from their sub-processors?
Contractual controls: Are sub-processors bound by data processing agreements with security obligations at least as stringent as those the provider commits to you?

The Procurement Conversation

When your security or procurement team evaluates an EOR provider, structure the conversation around these requests:

Current SOC 2 Type II report (or bridge letter if the new report is in progress). Read the scope description and the auditor’s findings, not just the certification page.
ISO 27001 certificate with scope statement. Verify the certification is current and issued by an accredited body.
Data Processing Agreement with cross-border transfer mechanisms specified.
Security questionnaire response. Use SIG (Standardized Information Gathering) or CAIQ (Consensus Assessments Initiative Questionnaire) if your organization has a standard framework.
Penetration test executive summary from the most recent engagement.
Sub-processor list with locations and data access descriptions.
Insurance coverage. Cyber liability insurance with coverage limits appropriate for the data volume processed. Ask for the coverage amount — providers with $5M+ cyber policies are demonstrating confidence in their security posture.

Providers that respond quickly and completely to these requests have done this before and built their security program with enterprise clients in mind. Providers that push back, delay, or provide vague responses are telling you where security falls on their priority list.

The EOR industry handles billions of dollars in payroll and the personal data of hundreds of thousands of employees worldwide. Security isn’t a feature — it’s the foundation. Verify it before you sign.
