Data Encryption in Employee Monitoring: The Standards to Meet

Your employee monitoring tool is capturing screenshots, activity logs, keystrokes, and attendance data right now. If that confidential data goes into the wrong hands from these tools, then you need to spend lots of money on fines and legal exposure. According to IBM's Cost of a Data Breach Report 2025, the global average breach cost has reached $4.4 million. It is also telling organizations that lack proper data encryption controls face even higher losses in breach risks.

Data encryption in employee monitoring software has become an important security requirement no organization can skip. This blog covers the employee monitoring software data encryption standards and compliance certifications you need to know, and the important questions you need to ask your monitoring tool vendor before purchasing it.

What Data an Employee Monitoring Tool Generates and Why Encryption Matters

Employee monitoring platforms generate seven types of data, and each data type has its own level of sensitivity and encryption requirement. The table below shows each data type, what it contains, the encryption requirement, and the standard that should apply.

The first thing you should look for while selecting employee monitoring software is the connection between the agent and the server. The agent is a software installed on each worker’s computer, and it sends activity data, screenshots, and other behavior signals back to the server continuously.

If that data is not protected, then anyone can block and get real-time access to it. This isn't a sophisticated attack. It is one of the easiest ways to compromise data from monitoring systems, but you can prevent this by encrypting all data between the agent and the server with TLS.

At Rest vs In Transit: The Two Data Encryption States That Both Matter

1. Data Encryption at Rest: AES-256

Any data you store within the servers of your employee monitoring software is known as data at rest. Screenshots, activity logs, attendance data, and recordings are all examples of data at rest. This data must be protected with encryption using a key called AES-256, as banks, hospitals, and governments do.

What AES-256 actually means in practice is simple. Even if an attacker breaks into the server, the data they find is completely unreadable without the decryption key.

If your employee monitoring platform is hosted on enterprise-grade cloud computing providers such as Microsoft Azure, all of your screenshots and activity logs are encrypted at rest.

The keys to decrypt the data are kept separately, and auditors check this key management as part of ISO 27001 and SOC 2 audits.

2. Data Encryption in Transit: TLS 1.2 and TLS 1.3

Data in transit refers to any monitoring information that is actively moving, from your employee's device to the platform server, from the server to your manager dashboards, and between the server and any connected tools like payroll or HR systems. All of that traffic needs to be encrypted using TLS 1.2 or TLS 1.3.

If your platform supports TLS 1.3, that is the preferred protocol for any new setup. TLS 1.2 is still acceptable, but is gradually being phased out by major cloud providers. If your monitoring tool is still running on TLS 1.0 or TLS 1.1, that is a serious vulnerability, as both versions are outdated and no longer considered safe.

Verify whether TLS encryption covers all traffic, not just the browser-to-dashboard connection. If the agent on your employee's device is sending data to the server without encryption, that gap puts your organization at risk, especially if you are operating under GDPR or similar data protection regulations.

Compliance Certifications That Indicate Proper Employee Monitoring Encryption

Compliance certifications are not just badges on a provider's website. They mean that an auditor has gone through the platform, checked their security measures, and confirmed that they meet the defined standards. This is more reliable than self-reported security claims. There are four certifications you should look out for in employee monitoring software:

Access Controls: The Layer That Encryption Alone Cannot Provide

Encryption protects your monitoring data from outside attackers. Access controls are a core element of employee monitoring data security They protect it from misuse within your organization. Encryption and access controls solve different problems. You need both to keep your monitoring data fully protected from both external and internal risks.

Role-based access controls verify that every person in your organization only sees the data relevant to their role. A team lead should see their own team's activity. An HR director should access HR relevant data across the organization. A payroll officer should see attendance and hours only. An IT administrator should configure the platform without having default access to every employee record.

Without these controls in place, even strong encryption falls short. If anyone with a login can pull up any employee's data, your encryption is only solving half the problem. Adding a data loss preventionlayer strengthens this further by detecting unauthorized data transfers and flagging unusual access patterns before they turn into a serious incident.

Six Data Encryption Questions to Ask Before You Deploy a Monitoring Platform

Before you deploy any monitoring platform, ask these six questions. The answers will quickly tell you whether a tool takes data security seriously or is just checking a box.

The sixth question is the one most organizations skip during evaluation, but it can be the most important. If your monitoring vendor cannot provide you with written evidence that they will destroy your data within a reasonable time frame after you cancel your subscription, your organization will remain legally liable for that data even though you are no longer using the service. For organizations operating under GDPR or CCPA, that is an ongoing compliance risk that does not disappear when the commercial relationship ends.

Conclusion

Data encryption in employee monitoring is a must. Any data your monitoring software collects, such as screenshots, activity logs, time and attendance, and geo-location, has legal and security implications. AES-256 encryption-at-rest and TLS 1.2 encryption-in-transit are the bare minimum you should expect when implementing a solution. ISO 27001:2022 and SOC 2 Type II are the accreditations you need to confirm an independent auditor has verified adherence to the standard. Strong access controls and a clear data retention and deletion policy complete the framework and keep it effective in the long run.

FAQs

How is employee monitoring data encrypted?

Employee monitoring data is encrypted in two states: at rest and in transit. Data at rest, including screenshots, activity logs, attendance records, and recordings stored on the server, should use AES-256 encryption. Data in transit, sent between the monitoring agent and the platform server, should use TLS 1.2 or TLS 1.3. Both protections are required for a monitoring platform to be properly secured.

What encryption standard should employee monitoring software use?

Employee monitoring software should use AES-256 for data at rest and TLS 1.2 or higher for data in transit. AES-256 is the standard used by governments and financial institutions, while TLS 1.3 is preferred for new implementations. TLS 1.0 and 1.1 are deprecated. The platform should also be hosted on enterprise-grade cloud infrastructure such as Microsoft Azure or AWS.

Is employee monitoring data protected under GDPR?

Employee monitoring data is treated as personal data under GDPR and subject to full GDPR obligations. This includes a lawful basis for processing, data minimization, defined retention limits, and technical security measures. GDPR Article 32 specifically requires encryption. Platforms used by organizations with EU employees must encrypt data at rest and in transit, restrict access, and support data subject rights.

What compliance certifications indicate good data security in a monitoring platform?

The key certifications to look for are SOC 2 Type II, ISO 27001:2022, GDPR compliance with a Data Processing Agreement, and HIPAA compliance for healthcare organizations. SOC 2 Type II is stronger than Type I because it covers a sustained audit period instead of a single point in time, and ISO 27001:2022 is the current version of the international standard.

Where is employee monitoring data stored?

Employee monitoring data should be stored in enterprise-grade cloud infrastructure such as Microsoft Azure, AWS, or Google Cloud, in certified data centers with 24/7 physical and digital security monitoring. For GDPR compliance, EU organizations should confirm data is stored in an EU-region data center. Ask your vendor specifically which cloud provider, which region, and what certifications apply.

Can the monitoring software vendor access our organization's monitoring data?

Vendor staff access to customer monitoring data should be strictly limited, logged, and governed by internal access control policies. Access should only be granted to support personnel for specific troubleshooting, be time-limited, and remain auditable. Request documentation of the vendor's internal access policy before signing. Any vendor that cannot provide this or does not restrict staff access is a security risk.
