As a self-funded company with 11 employees and 6 patents pending, we are small enough that one careless integration can expose everything, and we do not have a dedicated security team to catch it. Our answer was to limit the number of systems that hold sensitive information and demand role-based access from any vendor before we look at features. If a tool cannot restrict who sees what, it does not make the shortlist, however nice the interface is. We lost a little convenience, since some all-in-one platforms were off the table, but functionality held up because a lean stack with clean permissions is easier to train people on anyway. Rick Elmore, Founder/CEO, Simply Noted (simplynoted.com) --- ### Contain Connector Risk Through Token Scopes Our HR system was never really the scariest part of our HR stack. It was the eleven integrations that hung off the side of that system like a house of cards. I manage a distributed team of traders spread across the world in various time zones. Every new tool that we add to the tool belt wants to integrate with our HR system (run on TradingFXVPS) and requires an API token with read access to the entire employee directory (payroll, ATS, e-signature, etc.--even a Slack bot). Many of these tokens never expired and an audit of one of our recruiting plugins found that it had been stopped from running 8 months prior and was still pulling down passport scans and home addresses of applicants night and day. I look at these integrations with the same type of distrust that I look at open ports on servers. So, we made our HRIS the identity source for the company and we use SCIM provisioning through our Single Sign-On to add in the rest of the tools as needed. Access to all of these tools now dies within minutes of an employee's offboarding as opposed to some unknown time in the future. We scope tokens to the specific fields a tool needs to function and we refresh tokens every 90 days. The loss of functionality was minimal, as two nice-to-have applications that required access to the entire employee directory were quickly discontinued a week later. In the end, onboarding actually became faster as users were automatically provisioned with required applications. Vendors may tout the features of their applications, but each connector to the HRIS is an attack surface. So, count the number of connectors first, then the features. --- ### Require Human Review for Automated Selection The concern that shaped our choices most was what AI screening tools do with candidate data. We're an EU company, so GDPR isn't optional for us. Under Article 22, people have the right not to be subject to decisions made solely by automated means when those decisions significantly affect them, and being rejected for a job counts. The EU AI Act goes further and treats AI used in hiring as high-risk. That changed the questions we asked vendors. Before features or price, we wanted to know three things. Where is candidate data stored? How long do you keep it? Is it used to train your models? A surprising number of tools couldn't answer the last question clearly, and that was enough to rule them out. Resumes are full of personal information, and we didn't want ours, or our candidates', feeding someone else's product. The second rule was that software can sort, but a person decides. Automation is great at the tedious parts of hiring: scheduling interviews, sending updates, organizing applications. We use it there. But no candidate gets rejected because an algorithm scored them low. A person reviews that call and can explain it. Did that cost us some speed? A little. But it kept us out of the gray zone, and it means that if a candidate ever asks why they didn't move forward, we have a real answer, not "the system decided." My advice to anyone building an HR stack: ask the data questions first. A tool that saves your recruiters an hour a day isn't worth it if you can't explain what it does with people's information. --- ### Minimize Personnel Records From Day One Another topic associated with security that impacts HR technology choices immensely is the threat of leaking personal information of employees and candidates, which includes their CVs, contact details, salary details, and interview feedback. Speaking about my approach, I pursue data minimization and access controls without complicating the work of recruiters. First, I check the necessity of storing any personal data in a certain platform. Then, I make sure that people will be able to access the data they are supposed to according to their job role. I will also conduct audits of data retention policies and delete unnecessary data from there. It might be challenging to achieve a balance between security and convenience since recruiters are required to exchange information fast, hiring managers must get all information about candidates quickly, and employees do not want any extra bureaucracy. The important thing about security in relation to HR technology is that it should be considered at the very beginning of using it and not introduced in case of any problems. Protection of personal data is crucial to maintain trust of candidates and employees. --- ### Secure Compensation Through Self-Service Portals The main concern that has driven my choices here across both CheapForexVPS and my work in finance at TradingFXVPS is that compensation data is easily posted in places it shouldn't. Most data breaches don't actually start with some kind of sophisticated attack on salary information. Instead, it is often simply sent in an email as a PDF payslip, shared in a spreadsheet in a meeting (even if just "this once"), or a manager takes a screenshot of a team cost report and uploads it to a meeting sharing site. It's a matter of convenience vs. securing appropriate functionality. First, we treated this as a behavior problem, then as a software problem. All pay slip and benefits data is now available on a self-service portal (single sign-on, 2 factor login). This means we never have to email out sensitive information (as a pay slip, for example). We then set up role-based access to ensure that Finance can see full compensation information for all employees, line managers can see all the information for their team members, and that access is never inherited by someone who may move to a different role within the company. We review access on a quarterly basis to be surprised at how access has quietly been added. Functionality was not compromised by taking this approach as the secure way of working was also made the easiest way of working. Managers are able to view headcount and budgets in a clean list without seeing individuals' salaries and employees are able to access their own information at any time without having to ask anyone for it. In fact, trust in the secure way of working has grown to the point where employees are no longer looking for ways to work around it. --- ### Automate Complete Offboarding The concern that shaped everything for us was the leaver, not the hacker. When someone leaves a small company, their accounts often stay alive in five different tools for months because nobody owns the list. So when we built kjello, our own IT platform, offboarding became one click in the portal: every access is withdrawn and the device is collected. The same software profile that sets up a new hire is the list we use to remove them. --- ### Verify High-Stakes Change Requests Independently The biggest security concern was verifying identities during sensitive HR requests. Changes to bank details, access rights, contact information, or pay records can come through channels that seem genuine. A message from a hacked account can look convincing and lead to costly mistakes. We addressed this by requiring extra approval for high-impact changes. Requests involving payroll, identity, or private records need verification through a separate trusted channel. We also trained managers to treat urgency as a warning sign rather than a reason to skip checks. This kept routine updates simple while adding care to sensitive changes. Our goal was to protect private information without making every interaction difficult or relying on assumptions alone. --- ### Choose Outsourcing Over Autonomous Agents We considered using agentic AI specifically to handle the paperwork aspect of employee onboarding, but quickly backed away from that idea when we learned about AI agents' tendency to circumvent guardrails and leak data. That's simply not a risk we can afford to take. We've settled on human outsourcing specifically for this work because it's more reliable. --- ### Encrypt Document Transfers End to End One of the most significant security issues that influenced our approach to HR technology was the absence of a verified custody chain in the transfer from paper files to electronic documentation. Paper documents may take up space; however, they exist at a specified physical site. In comparison, if electronic information is not kept in a well-designed system, it can land in unsecured local downloads and encrypted email accounts, thus compromising privacy and creating fragmented data paths. This practice considerably increases the likelihood of a data breach when the information is of a sensitive nature, e.g. tax numbers and bank account numbers. To solve this issue without slowing down the hiring process, we shifted our attention from documents to the system used to manage the documents. Instead of the traditional email exchange we implemented a secure process during which documents would be encrypted throughout the whole process of passing them from one party to another. As a result, we achieved the complicated audit trail that captures all stages of the process-from generating the first employment proposal to getting the last signature. The key to achieving practicality was making the security systems invisible to the end-users. We began to generate auditary reports and other documents automatically which allowed recruiters avoid extra administrative work for the sake of keeping everything within the law. We tried to make security function as an infrastructural element rather than the whole process made according to the security checklist. --- ### Centralize Indian ID and Banking Files Scanned PAN cards and cancelled cheques. Those used to reach HR as photos in a chat thread, sitting next to somebody's lunch plans. Our staff are spread across India and the company is headquartered in Dubai, so these records cross a border by default. We moved every ID and bank document into a single HR system where only payroll and 2 people in HR can open the bank fields. Employees upload their own files from a phone in about a minute. It needed no training. The old chat threads annoy me to this day, since you can delete a photo and never be sure every copy is gone. --- ### Separate Identity From Personal Assessments The concern that shaped our entire approach at Pigment was data intimacy. We are not storing payroll records or PTO balances. We are storing how people describe their own operating systems: what energizes them, what conditions they need, how they process feedback, where they struggle. That data is more sensitive than most HR tech handles because it is personal in a way that transactional data is not. If someone's salary leaks, that is a privacy violation. If someone's self-assessment about their weaknesses and insecurities leaks, that is a trust violation that can affect their career. The decision this forced was building data architecture where the assessment results are separated from identifying information at the storage level. Even an internal engineer with database access cannot casually browse someone's profile attached to their name. That separation added engineering complexity we could have avoided, but skipping it would have been irresponsible given what we are asking people to share. The functionality tradeoff was real. Some features would be easier to build if everything lived in one connected graph. Analytics would be richer if we could cross-reference assessment data with usage patterns. We chose the harder architecture because the product only works if people trust it enough to be honest. And honesty requires knowing their vulnerability is protected, not just promised. --- ### Set Deletion Schedules Before Deployment Data retention was a key privacy concern for us. HR systems can make it easy to keep records forever, especially when information moves from recruiting into wider workforce processes. This creates unnecessary risks and makes it harder to meet deletion requirements. We therefore looked beyond data collection and checked how information could be removed from backups, exports, and connected applications. We addressed this by assigning ownership to each data category and setting retention periods before deployment. Our reviews covered offboarding steps, export controls, and providers' ability to confirm data deletion. We kept the process simple by retaining only the information needed for daily operations. Clear schedules reduced cleanup work, made records easier to manage, and turned privacy into a regular habit. --- ### Define Breach Notification Duties Upfront The security concern that mattered most was incident notification. A delayed notice can prevent timely credential resets, communication with affected people, and checks for exposed employee data. Security promises matter less when responsibilities during a crisis are unclear. Clear response plans help ensure that problems are handled quickly and properly. Incident response commitments were reviewed alongside technical controls. The review covered notification timelines, escalation contacts, testing practices, and clear rules for subcontractors handling data. An internal playbook assigned responsibilities to HR, legal, finance, and leadership before an incident occurred. This approach protected functionality while allowing useful automation and collaboration, ensuring that systems handling sensitive records fit into a response plan that people could follow under pressure. --- ### Capture Actionable Record-Level Audit Evidence The concern that carried the most weight was whether audit trails were meaningful enough to investigate a privacy incident. Many systems record activity, but vague logs are not useful when trying to determine who viewed a document, changed a record, or exported employee information. Security without visibility makes accountability largely theoretical. I selected configurations that capture significant actions with clear timestamps, user identities, and record-level details. Access reviews now rely on evidence rather than assumptions, and unusual activity can be investigated quickly. The result is not a more restrictive environment, but a more accountable one where legitimate work continues without sacrificing traceability. --- ### Govern Every Third-Party Connection We were especially cautious about integrations. HR systems rarely stand alone. They connect with recruiting, payroll, benefits, identity, finance, and collaboration tools. Each connection can create a hidden path to employee data, even when the original system has strong controls. A stack can look secure on paper while permissions become difficult to trace across those handoffs. Our response was to favor clarity over convenience. Before connecting a system, we mapped what data would move, who could access it, and whether the integration truly needed ongoing synchronization. We also assigned an internal owner to each connection rather than treating integrations as permanent background infrastructure. That approach preserved useful automation while limiting data flows that had no operational purpose. The practical lesson is that every integration should earn its access to employee information. --- ### Ban Workplace Surveillance Archives Employee monitoring capabilities were a red line in HR technology decisions. Tools designed to improve attendance or productivity can normalize collection of screenshots, keystrokes, location signals, or activity scores. In an organization built around distributed execution, trust weakens when measurement exceeds the work outcome. I favored systems that supported administration without creating a surveillance archive. The safeguard was a data-use boundary. Attendance and access events could resolve questions, but behavioral tracking was disabled, retention periods were limited, and any exception required approval. Managers received guidance on using performance evidence tied to deliverables, client outcomes, and expectations. Functionality stayed strong because the stack supported coordination, while privacy rules prevented convenience data from becoming a proxy for managerial judgment. --- ### Enforce Least-Privilege Employee Views Unnecessary access to employee records is the privacy concern I'd put first when evaluating an HR tool. A manager needs to approve time off; a payroll specialist needs compensation data. A broad profile for both roles may be easy to configure, but it exposes information outside each person's job. The risk grows when somebody changes roles and retains access, or when an integration receives a wider employee feed than its purpose calls for. Our general security approach uses least privilege and fine-grained access. For an HR stack, I'd write down the fields and actions each workflow needs before connecting the systems. A manager's time-off screen can show the request and its status without pay or private contact details. A service checking employment status can receive that answer without taking the personnel record with it. I'd test the API through accounts assigned to different roles, including one whose permissions have changed. The interface may hide a field while the API still returns it, so the actual response matters more than an access diagram. The employee still submits a request, the manager makes the decision and payroll processes the relevant change in its own system. Narrowing what each role and integration can see preserves those functions. Treat access as part of product selection: if a vendor can't separate the views or constrain its feeds, a convenient interface won't make up for that limitation. I would start with the work people need to complete and grant the data necessary for that work. --- ### Protect Identities in Small-Group Dashboards A concern that influenced our decisions was the false sense of safety created by aggregated dashboards. In smaller teams, charts filtered by location, tenure, or manager can reveal an individual's identity even when names are hidden. We recognized that privacy risks often come from combining ordinary details rather than from a major data breach. To reduce these risks, we focused on setting clear limits on how information could be viewed and used. We looked for minimum group size settings, rules to hide sensitive results, and access levels based on each person's role. This kept reports useful while allowing leaders to understand patterns without exploring individual circumstances. We also trained teams to understand that having a filter available does not mean it is appropriate to use. This approach helped protect people's dignity and supported better decisions. --- ### Authenticate Vendor HR Emails When evaluating third-party HR platforms, our biggest security concern was email impersonation and payroll phishing. Modern HR tools constantly send onboarding paperwork, benefits alerts, and payroll updates under corporate domain names, which makes them prime targets for domain spoofing if sending permissions aren't tightly locked down. To address this without disrupting employee communication, we prioritized automated email authentication. Ensuring every HR tool properly aligns with SPF, DKIM, and strict DMARC policies lets outside vendors send legitimate alerts on our behalf while stopping attackers from impersonating HR to siphon direct deposits or employee data. The HR team keeps their preferred software, and employees can trust that messages claiming to come from HR actually do. --- ### Delete Excess Information Quarterly “The concern that reshaped our thinking: employee data collected by HR tools often lives far beyond its purpose. When evaluating HR platforms, I now ask where the data is stored, who else can access it, and what happens when someone leaves. The fix was boring but effective — we added a data-retention clause to every vendor contract and run a quarterly access review. Most HR tech stacks accumulate “just in case” data; the privacy win is deleting what you don't need. — Shivam Sharma, Tech & Cybersecurity Writer, TechReview.si” --- ### Vet Platforms Like Production Databases For a small firm, the HR tech decision that mattered most was payroll and background-check data: SSNs, bank accounts, home addresses. My rule: employee PII gets the same controls as customer data. We chose the HR platform offering SSO with our identity provider, field-level encryption, and US-only data residency — and rejected a cheaper option that wouldn't commit to residency in writing. The lesson I give clients: HR systems are breach magnets because they centralize exactly what attackers want. Vet them like a production database, not office software. --- ### Anonymize Staff Inputs Before Model Use The main concern for me when applying AI to HR admin tasks is where employee data is stored. As I previously described automating HR admin work at TradingFXVPS, the obvious first step would be to feed all staff records into an AI model to allow it to do the rest. However, the risk of employee data being stored on 3rd party servers, under unknown terms and conditions, far outweighs the temporary inconvenience of doing things the hard way. So I chose to split the task and write Python scripts to handle the parts that involved personal data. The scripts would process the data locally, change names to IDs of staff members who were mentioned, remove all unnecessary fields, and then pass on the required information to the AI model. After the model had completed the required task (e.g. to draft a leave of absence reply or to summarize a question on a company policy), the IDs would get matched back up to the real people in the admin system that I had set up. Actually, it worked really well for us in terms of functionality. The model was unable to understand who Ahmad was, but it was able to very elegantly summarize a claims summary for us. In terms of hours, it saved us hours and hours to perform the same function as a human being. We sacrifice a little bit of convenience and actually have to define what fields we're going to send out of our tools, but that's a one-time effort. One simple step to mitigate risk for now would be to list all tools currently used to manage employee information, check the data retention terms and the model training data for each, and disable training with your employee information wherever possible. I have found, for example, that one of the current tools of choice has default settings of "on" for data retention and training with employee data. This is not a foolproof solution and will no doubt change over time, but it's a good starting point. ## Related - [How Do You Balance Employee Privacy With Policy Compliance?](https://chrodaily.com/qa/how-do-you-balance-employee-privacy-with-policy-compliance.md) - [3 Ways HR Technology Solved Significant Business Problems"](https://chrodaily.com/qa/3-ways-hr-technology-solved-significant-business-problems.md) - [How Have You Successfully Integrated HR Technology into Daily Operations?](https://chrodaily.com/qa/how-have-you-successfully-integrated-hr-technology-into-daily-operations.md) - [How HR Leaders Turn Employee Feedback Into Trust](https://chrodaily.com/qa/how-hr-leaders-turn-employee-feedback-into-trust.md)
