The Importance of Data Security in HR and Payroll

In the shared services world, we pride ourselves on precision, scale, and trust. But trust is fragile—and nothing tests it more than a breach of employee data. As someone who’s spent over two decades in HR leadership, I’ve seen how data security in HR and payroll has evolved from a compliance checkbox to a boardroom priority.

Let’s be clear: HR data is under siege. And the stakes have never been higher.

The Alarming Reality: HR Data Is a Prime Target

A recent analysis of 141 million leaked files revealed that HR data appeared in 82% of data breaches—including payroll, resumes, and personally identifiable information (PII). Recruitment data alone showed up in 58% of breaches.

In 2023, employee data breaches rose by 41%, with ransomware attacks on payroll systems increasing by 57%. These aren’t just numbers—they’re a wake-up call.

Why HR & Payroll Are High-Value Targets

HR systems are a goldmine for cybercriminals:

  • Names, addresses, bank details
  • Salary, tax, and benefits data
  • Health records and disciplinary history

In one breach at DISA Global Solutions, over 3.3 million employee records were compromised, most of it from payroll and HR databases. The cost per record? Over \ $180. Multiply that across thousands of employees, and you’re staring at a seven-figure problem.

Case Study: The Phoenix Payroll Fiasco

Canada’s federal payroll overhaul—the Phoenix system—was meant to modernize operations. Instead, it became a cautionary tale. Poor planning, underestimated complexity, and data quality issues led to inaccurate pay, rising costs, and reputational damage.

Lesson? HR tech without robust data governance is a liability.

What Strategic HR Leaders Must Do

As Strategic HR Leaders, we are not just culture custodians—we are guardians of trust and data integrity. Here’s how we lead from the front:

1. Embed Security into HR Tech Strategy
  • Choose platforms with multi-factor authentication, encryption, and real-time threat detection.
  • Partner with CIOs and CISOs to ensure security is baked into every system upgrade.
2. Champion Data Governance
  • Define clear data ownership, retention, and access protocols.
  • Conduct regular audits and vulnerability assessments.
3. Educate Employees—Continuously
  • 68% of breaches involve a human element.
  • Train teams to spot phishing, use strong passwords, and handle sensitive data responsibly.
4. Vet Third-Party Vendors Rigorously
  • Outsourcing payroll? Ensure vendors meet ISO 27001 or SOC 2 standards.
  • Review SLAs and incident response plans regularly.
5. Prepare for the Worst—Proactively
  • Have a data breach response playbook.
  • Communicate transparently with affected employees and regulators.

In Shared Services, Scale Amplifies Risk

One breach in a shared services model can ripple across geographies and business units. That’s why standardization, automation, and monitoring must go hand-in-hand with robust security protocols.
