Introducing Micro Guard™


Micro Guard™ is the advanced microphone protection solution for your Android™ device. With just a single click, you can activate powerful protection that prevents any hacker, spy, or spyware from eavesdropping on your conversations.

Prevent Spying


Not only millions of users but also former FBI chiefs take precautions by covering their webcams and microphones. The reason is clear: everyone is at risk of being spied on!


Since June 2013, following the revelations by whistleblower Snowden, we have become increasingly aware of the threats posed by hackers and spyware. These malicious entities have found ways to misuse the integrated microphones of mobile devices without alerting users.

Hear Nothing – For Those Who Should Not


The Micro Blocker feature effectively blocks all apps and processes that attempt to access your device's microphone, ensuring complete privacy and security. The intelligent Deep Detective™ feature goes even further by detecting previously unknown attacks and proactively restricting any possibility of surveillance.

Deep Detective™: A Smart Invention Against (Un)Known Threats


Our optional Deep Detective™ Live anti-spyware scanner detects various fraudulent elements with thousands of attack signatures. Its advanced heuristic methods make it an essential tool for those concerned about microphone misuse. This feature is available through a subscription.

Combine Micro Guard™ with Camera Guard™


Enhance your protection by combining Micro Guard™ with our Camera Guard™ app to safeguard both your device's microphone and camera. Micro Guard™ also integrates seamlessly with other existing security solutions.
