60% of organizations now evaluate partners based on cybersecurity risk. If you're not asking hard questions about your HR vendors' security practices, you're trusting them blindly with your most sensitive data.
When a vendor gets breached, it's still your employees whose data is exposed. It's still your company that faces the notification requirements, the lawsuits, and the reputational damage.
The Vendor Risk Reality
- • Third-party breaches are increasingly common attack vectors
- • You're responsible for protecting employee data—even data held by vendors
- • Privacy laws require vendor due diligence
- • A vendor breach can be more damaging than a direct attack
Security Questions Every HR Vendor Should Answer
Certifications & Audits
Ask for: SOC 2 Type II report, ISO 27001 certification, or equivalent
These certifications demonstrate that an independent auditor has verified the vendor's security practices meet established standards.
Data Encryption
Ask: "Is our data encrypted at rest and in transit? What encryption standards do you use?"
Look for AES-256 encryption at rest and TLS 1.2+ in transit. Anything less is outdated.
Data Location & Access
Ask: "Where is our data stored? Who has access? How is access controlled?"
Understand which countries your data may pass through—this has regulatory implications.
Incident Response
Ask: "What's your breach notification process? How quickly would we be notified?"
You need time to meet your own notification obligations. Delayed vendor notification creates legal exposure.
Subprocessor Management
Ask: "Do you use subcontractors or subprocessors? How do you vet their security?"
Your vendor's vendor can be a weak link. Know the full chain of custody for your data.
Red Flags in Vendor Security
No independent security certification
"Trust us" isn't a security strategy. Reputable vendors have third-party audits.
Reluctance to discuss security practices
Vendors with strong security are proud to discuss it. Evasiveness is a warning sign.
No data processing agreement
Privacy laws often require written agreements about how vendors handle your data.
History of breaches without improvement
Check news for past incidents. One breach might be bad luck. Patterns indicate systemic issues.
Want a partner with enterprise-grade security?
PEOs invest heavily in security—it's core to their business model.
Why PEO Security Standards Are Higher
PEOs handle sensitive data for thousands of companies. A security failure would be catastrophic for their entire business. That concentration of risk drives higher security investments than any individual small business could justify.
What Quality PEOs Provide
- • SOC 2 Type II certified operations
- • Enterprise-grade encryption
- • 24/7 security operations center
- • Regular penetration testing
- • Comprehensive incident response plans
- • Rigorous vendor management programs
Consolidation Benefits
Instead of managing security for multiple vendors (payroll, benefits, HRIS, etc.), a PEO consolidates these functions—reducing your vendor count and your attack surface.
Due Diligence Made Easier
When evaluating a PEO, you're doing due diligence on one comprehensive partner instead of multiple point-solution vendors. That's simpler—and more likely to actually get done.
Choose a Partner You Can Trust
A PEO with strong security practices protects your employee data better than most small businesses can on their own.
