Digital privacy has become one of the most discussed topics of the last decade.
With WhatsApp firmly established as the leading communication tool on the planet, it's natural that questions arise about the security of conversations and the possibility of monitoring them.
Whether it's parents concerned about their children's safety or companies managing corporate devices, the search for monitoring solutions is growing every day.
However, the internet is full of misleading promises. In this article, we will separate the myths from the truths and present the tools that truly deliver on their promises, ethically and securely.
Before we delve into the apps, we need to clarify one crucial point: There is no such thing as technological magic.
Many websites promise that simply typing someone's phone number into a search field will give you immediate access to their conversations. This is a scam.
WhatsApp uses end-to-end encryption, which means that only the sender and receiver can read the content.
To monitor an account, legitimate tools require some type of integration with the device or with cloud backup.
Avoid websites that ask for payments via Pix (Brazil's instant payment system) or completion of surveys in exchange for "remote access by phone number," as they usually aim to steal your data or install viruses on your device.
If you're looking for a real solution for parental control or security, the names below are market leaders. Each has a different approach, adapting to specific needs.
THE mSpy It is considered the industry's "gold standard." It not only monitors WhatsApp but turns the target device into an open book for the administrator. It's the ideal choice for those who need a complete history and don't want to miss any details.
THE EyeZy It arrived on the market to make life easier for those who don't have time to spend all day looking at message logs. It uses a technology called "Smart Alerts," which filters out what is relevant.
THE KidsGuard Pro It stands out for its ease of installation. It is focused on an audience that doesn't want to deal with complex processes like... root (on Android) or jailbreak (on iOS).
To help you make your decision, we've put together a table comparing the main features of each software:
| Functionality | mSpy | EyeZy | KidsGuard Pro |
| Read Messages | Yes (including deleted ones) | Yes | Yes |
| View Media (Photos/Video) | Yes | Yes | Yes |
| GPS location | Yes (With history) | Yes (With alerts) | Yes |
| Call Recording | Yes | No | Yes |
| Online/Offline Status | Yes | Yes | Yes |
| Difficulty Level | Average | Easy | Very easy |
| Invisible Mode | Yes | Yes | Yes |
If you're reading this article and are concerned about your privacy, know that WhatsApp offers tools to help you protect yourself. Security is a two-way street.
It is crucial to remember that device monitoring must be done within the law.
In Brazil, the use of these tools is permitted for parental control (parents monitoring underage children) or in corporate devices, provided the employee is aware of the company's usage policy.
Monitoring adults without their consent may constitute the crime of unauthorized access to a computer system.
Monitoring WhatsApp by number isn't as simple as scammers try to portray, but with the right tools, it's possible to ensure the safety of those we love.
THE mSpy and the EyeZy They lead in terms of resources, while WaStat It offers a simple alternative for those seeking only to understand usage patterns.
Choose the tool that best suits your budget and technical needs, but always prioritize safety and ethics when using these technologies.
The digital world is vast, and being well-informed is your best protection.
