When is your payroll software a security risk: how cloud-native platforms protect SMEs
"It won't happen to us because we're too small."
Many small and medium-sized businesses rely on this logic when considering cybercrime risks. Surely criminals will target larger organisations that promise a more substantial payoff. Why would they bother with a small company when much larger fish are available to catch?
Unfortunately, this is a dangerous myth. Online criminals frequently target small businesses, and they often focus specifically on payroll software.
Why payroll systems are attractive targets for cybercriminals
Large businesses can afford robust security infrastructure, making them harder to attack. Cybercriminals know this and often pursue softer targets. But there's another reason payroll systems are prime targets: they contain valuable data.
Criminals don't just want money. They want personal and banking details that can be resold to other criminal groups for fraud or identity theft. A payroll system contains exactly this information, making it extraordinarily attractive.
Why small businesses are prime targets
Small and medium-sized businesses are not too small to avoid attacks, they are prime targets. According to Cybercrime Magazine, four out of five small businesses experienced a breach in 2025, and SMEs face 350% more social engineering and impersonation attacks than large enterprises.
Real payroll threats facing SMEs
Payroll systems are frequent targets for sophisticated attacks. In 2025, Microsoft Threat Intelligence uncovered "payroll pirate" attacks against universities that hijacked and diverted salaries to attackers' accounts. But this represents only one category of threat.
Other common payroll attacks include:
β Changing deposit or bank routing details to redirect employee payments.
β Encrypting payroll data just before a salary processing window to pressure businesses into paying ransom.
β Threatening to release confidential salary information publicly, undermining competitiveness and employee relationships.
β Gaining access to payroll systems to reach connected finance and HR systems.
The interconnected risk: payroll as a gateway
Many attackers don't just want to steal from payroll itself. They want access to the payroll system because of its proximity to other critical business systems. A payroll system contains employee email addresses that criminals can use to target staff with phishing attacks. Once they gain access to payroll and HR, they can reach sales data, customer records, executive travel details, and much more.
How SMEs can improve payroll security affordably
Understanding threats is the first step, but security improvements don't have to be costly. Criminals typically target outdated or unpatched software with basic security features. A modern, subscription-based payroll platform can add significant security without the expense of building infrastructure from scratch.
What cloud-native payroll platforms provide
Software vendors maintain and update cloud-based payroll platforms automatically, eliminating the need for SMEs to manage patches and updates themselves. This includes:
- Continuous security monitoring with dedicated teams tracking cybercrime trends and vulnerability reports.
- Regular software updates that include and improve features such as multi-factor authentication.
- Role-based access and separation of duties that limit what criminals can access even if they gain entry.
- Regular reports, audit trails, and approval workflows that prevent and detect fraudulent system changes.
- Vendor-side backups as an additional layer of protection against data loss.
- 24/7 infrastructure monitoring, automated alerting, strong encryption, and compliance certifications including ISO 27001, SOC 1 & SOC 2, and privacy law compliance such as POPIA and GDPR.
What SMEs must do on their end
SMEs remain accountable for their own security practices. Training staff in cyber hygiene and creating policies that support features like multi-factor authentication are essential responsibilities. A responsible software vendor will support these efforts by providing payroll platforms that embed security at the foundation and helping customers optimise their setup.
Choosing a payroll vendor that takes security seriously
Your payroll vendor must demonstrate that they take security seriously. They should help you design roles, provide staff training, answer your questions, and show proof of compliance with security standards. This partnership approach removes considerable pressure from the business and ensures you gain full value from your payroll software.
The right vendor partnership, one that combines robust cloud-native security with your own cyber hygiene practices, transforms payroll from a potential security liability into a protected asset.
