HR departments deal with a lot more sensitive information than people usually realise. Names and addresses are the obvious part. Then there are bank details, salary records, identification documents, employment contracts, absence records, tax information and sometimes medical information too. And most of it is no longer sitting in a filing cabinet. It’s moving between HR platforms, payroll software, recruitment systems, employee portals and cloud storage. That makes everyday HR work easier, but it also gives attackers more opportunities to get hold of information they should never have. For HR teams, cybersecurity is now part of the job.
Why HR Data Attracts Attackers
There’s a simple reason HR data is valuable: there’s a lot of it in one place. A compromised HR account could give someone access to employee records, internal documents or payroll information. In some cases, attackers may not even need sophisticated malware. A convincing phishing email can be enough. That’s becoming harder to deal with as well.
AI can help attackers create much more believable emails and fake profiles. An email supposedly coming from a manager may sound perfectly normal, with the right tone and details. A fake candidate profile can also look convincing enough to make an initial screening difficult. So telling employees to “watch out for phishing” isn’t really enough anymore. Good security needs technology behind it.
Too Much Access Can Be a Problem
Modern HR software usually works through permissions. The problem is that permissions can accumulate over time. Someone moves from recruitment to another department but keeps their old access. A temporary administrator account is never removed. An employee leaves, but one of their accounts remains active. These things happen.
The European Data Protection Board recommends reviewing authorisations regularly and removing access that’s no longer needed. It also highlights the importance of appropriate technical and organisational measures when protecting personal data.
A sensible approach is to give people access to what they actually need, rather than everything they might possibly need. Multi-factor authentication should also be standard, especially for accounts with administrative access.
What About External HR Providers?
Very few HR departments operate completely on their own anymore. There may be a payroll provider, recruitment platform, benefits system, background-checking company, HR consultancy and several other SaaS tools involved in the employee lifecycle. Every one of those connections deserves a basic security check. Where is the data stored? Who can see it? Is it being shared with another provider? How long will it be kept? What happens when the contract ends?
The same applies when a company brings in an outside specialist for something like job evaluation services. The service itself may be completely separate from cybersecurity, but the organisation still needs to understand what employee information is being shared and how that information will be handled. That should be part of vendor selection, not something checked after the contract has already been signed.
Compliance Is Not Just a Privacy Policy
A privacy policy on the company website is useful. It is not the whole compliance process. Under GDPR, organisations need a valid legal basis for processing personal information and have to follow principles around data minimisation, purpose limitation, accuracy, storage and confidentiality. In practical terms, this means HR should know why particular information is being collected and whether it actually needs to be collected. It also means keeping data forever is not a sensible default.
Old employee files, outdated recruitment records and documents sitting in forgotten folders can create unnecessary risk. Retention rules should determine what needs to stay, what can be archived and what should be securely deleted.
Employees also have certain rights over their personal information, including rights relating to access, correction and erasure, subject to the conditions set out in data protection law. HR systems need processes that can actually respond to those requests.
Do Not Forget About People Leaving
Offboarding gets plenty of attention from an HR perspective, but the security side can sometimes get missed. When someone leaves, access should be removed from email, HR systems, shared drives, VPNs and other relevant platforms. Company laptops and other devices need to be recovered too. And it should happen promptly.
The same thing applies when an employee changes roles. Their old permissions may no longer make sense, even though they are still working for the company. A regular access review can catch these gaps before they turn into a problem.
HR and IT Need to Talk More
HR cannot handle all of this alone, and IT cannot either. IT teams understand authentication, encryption, devices, monitoring and system security. HR knows what employee information is collected, why it is needed and who uses it. Legal and compliance teams bring another piece of the picture. Those areas need to overlap.
A useful exercise is simply mapping the employee data journey. Start with recruitment. Follow the information through onboarding, payroll, benefits, performance management and eventually offboarding. It can be surprising how many systems touch the same employee record. From there, gaps become much easier to spot.
The Technology Will Keep Changing
HR technology is not slowing down. AI-assisted recruitment, automated workflows, employee self-service platforms and cloud-based systems are becoming part of normal workplace operations. That is not necessarily a problem. The bigger issue is adding new technology without thinking about what happens to the data moving through it.
Security does not need to make HR technology complicated. Strong passwords and MFA, sensible permissions, properly checked vendors, clear retention rules and a reliable offboarding process already cover a lot of ground. The important part is making those controls routine. Because when HR data is involved, a small security shortcut can affect a lot of people.
