Transparent monitoring tells employees what is recorded and lets them see it. Stealth monitoring hides the software from the person being monitored. Transparent monitoring is the right default for almost every employer: it is lawful in more places, it protects trust and it still produces accurate records. Stealth monitoring belongs in short, specific investigations approved at a senior level.
Key takeaways
- Transparent is the default. Stealth is the exception that needs a written reason.
- Several US states require notice, and UK and EU rules allow hidden monitoring only in exceptional cases.
- 47% of monitored US workers worry their employer uses technology to spy on them.
- Knowing the rules does not spoil the data. It makes the data defensible.
What is the difference?
| Transparent monitoring | Stealth monitoring | |
|---|---|---|
| Does the employee know? | Yes, before it starts | No, or only in general terms |
| Is the software visible? | Yes, with its settings | Hidden icon and process |
| Can employees see their own data? | Usually | No |
| Legal position | Meets notice laws when done properly | Unlawful or restricted in many places |
| Effect on trust | Manageable, if the rules are fair | Severe if discovered |
| Typical use | Time, attendance and productivity records | A named investigation |
What does the law say about hidden monitoring?
United States. New York, Connecticut and Delaware require employers to give notice of electronic monitoring. Monitoring nobody was told about cannot satisfy those laws.
United Kingdom. The regulator says covert monitoring is unlikely to be justified in most usual circumstances.
When covert monitoring may be justified, under ICO guidance
- Circumstances
- Exceptional, such as suspected criminal activity or gross misconduct
- Approval
- Senior management
- Scope
- Aimed at gathering evidence for a specific investigation
- Duration
- The shortest time possible, ending with the investigation
Europe. In Bărbulescu v. Romania in 2017, the European Court of Human Rights set out the factors that decide whether monitoring is proportionate. The first is whether the employee was told in advance. The others are how far the monitoring went, whether the employer had legitimate reasons, whether a less intrusive method was available and what safeguards were in place.
What does hidden monitoring do to people?
The American Psychological Association's 2023 survey asked workers whether they worry that their employer uses technology to spy on them.
- Monitored workers47%
- All workers34%
- Workers who are not monitored22%

That worry exists even where monitoring is disclosed. Hidden software confirms it. When staff find an agent nobody mentioned, the question stops being what was recorded and becomes what else they were not told.
Does telling people ruin the data?
This is the usual argument for stealth: people behave differently when they know. Three answers.
- For time and attendance, behaving differently is the point. You want accurate hours, and people who know hours are recorded tend to record them.
- Gaming is a measurement problem. If people fake activity, the measure rewards activity. Fix the measure. See mouse jigglers and fake activity.
- Hidden data is hard to use. A warning or dismissal based on records the employee never knew existed invites a dispute you could have avoided.
When is stealth monitoring defensible?
Rarely, and never as the everyday setup. The cases that hold up look like this: a specific suspicion of serious wrongdoing, a written decision by senior management, legal advice, a narrow scope and an end date.
Fits a covert investigation
- Suspected theft of client data by a named person
- Suspected fraud, with evidence that would be destroyed if the person were warned
- A time limit and a written sign-off
Does not
- General curiosity about what remote staff do
- A manager's doubt about one person's effort
- Monitoring that never ends
How do you run transparent monitoring well?
Publish the rules
What is recorded, when, who sees it and how long it is kept. Use the policy template.
Show the software
Open it in a team meeting. Let people see what a manager sees.
Give people their own data
Access to their own record removes most suspicion.
Set limits the software enforces
Working hours only, blur for screenshots, a pause for private tasks.
Review and adjust
Ask after a month what felt wrong, and change it.

Which approach is BirdsEye built for?
The transparent one. The BirdsEye desktop agent is an application employees open and use, and it has a rules screen that shows each person the tracking hours, screenshot interval, blur level and idle threshold applied to them.
- Employees can open their own day, activity log and screenshots, unless the company switches that off.
- Anyone can pause for a set time or until they resume, and the agent reminds them they are paused.
- Captures are refused outside working hours, including captures a manager requests on demand.
- Managers see only the teams they manage.

Frequently asked questions
Is stealth employee monitoring legal?
It depends on where you are. States such as New York, Connecticut and Delaware require notice. In the UK and EU, hidden monitoring is only for exceptional cases, such as suspected criminal activity, and must be limited and approved at a senior level.
Why would an employer use stealth monitoring?
Usually for an investigation into serious misconduct where warning the person would destroy evidence. Using it as a routine way to manage staff is hard to justify legally and damages trust.
Is transparent monitoring less effective?
No. For hours, attendance and project time it works as well or better, because people keep accurate records when they know records are kept. It also produces evidence you can use openly.
Can employees tell if stealth software is installed?
Sometimes. Hidden tools avoid icons and use obscure process names, so a lack of signs proves little. See how to tell if your employer is monitoring your computer.
