The Android operating system, used by 78% of mobile devices in Brazil, is characterized by its connectivity and compatibility with various other devices, systems, and applications. This brings visible benefits to the daily work routine. However, as with everything in corporate life, there is a catch: the incorrect use of these types of devices can be costly for the company.
Recent research has revealed that one in eight smartphones in Brazil is infected with malware, which can cause data leaks and even complications for companies under the General Data Protection Law, which can even punish companies that act negligently with the data under their responsibility.
It is important for companies to be careful and seek to prevent the misuse of corporate devices.
Considering this scenario, in this text we present 3 tools that, together, can add an extra layer of protection to Android devices, making access more secure and protecting user and company data. These are:
- Password Manager: LastPass
- Antivirus: Avast
- Web content filter: Lumiun DNS
In the following lines you will see the characteristics of each one and how the tools work together to establish effective protection on Android devices and more:
A step-by-step guide on how to install each of them on your Android device.
1. LastPass: Manage and protect your passwords
Protecting passwords seems extremely simple, easy, and even a little "silly," but according to research by Kaspersky, it's very important and has caused a lot of headaches for small and medium-sized businesses in Brazil when neglected.
Research indicates that password theft has increased by 143% over the past year in Brazil, specifically among small and medium-sized businesses. Within this same business environment, an internet security company reports that Brazil leads the ranking of cyberattacks.
These data clearly demonstrate the reasons for using an account and password manager like LastPass.
LastPass is a password manager that protects your passwords and personal information by encrypting the characters entered in the username and password fields .
With it, you can store passwords and logins, create online shopping profiles, generate strong passwords through suggestions or the app's own generator, and securely locate personal information.

For the company, the benefits are extremely significant:
- Eliminate password reuse by employees – With LastPass's password generator, you eliminate the continuous use of passwords for multiple logins by employees, increasing the security of company passwords.
- Manage your passwords in one place – Don't rely on spreadsheets and oversee everything with a complete administration dashboard.
- Protect confidential data – In addition to passwords and credentials, notes and information can be protected by adopting a LastPass security model.
- It makes password sharing easy and secure – Share credentials with employees and affiliates, manage access, and securely manage passwords.
Maintaining strong and secure passwords is the first step towards effective security for Android devices in businesses. If you have this concern, consider using tools like LastPass immediately. The solution is simple and comprehensive.
