#### NOTE

1. Emulator detection is more suitable for games, this feature is specifically for game developers who don't want their games to be played via an emulator for certain reasons.

2. HTTP Capture detection and SSL Pinning are different but share the same goal of protecting network communications from malicious activities commonly conducted via MITM attacks. The difference between the two is that HTTP Capture detection directly identifies network capture activities such as HTTP, while SSL Pinning verifies the authenticity and integrity of the server’s SSL certificate.

3. **Screen Capture protection and Anti auto clicker are not activated in this demo app!**

# TODO
- Fake GPS Detection.
- Integration with servers for more convenient detection monitoring and control.
- Built-in Anti-Malware (Threat detection from other applications, similar to what Play Protect does).

# FAQ

**1. Support Most Android Version**

- Support Android 5.0 - 17 (API level 21 - 37).
- Support armeabi-v7a, arm64-v8a and x86_64. (We are discontinuing x86 support as it is no longer relevant to modern versions of Android.)
- Support Android Framework App (Flutter, React Native)

**2. Extremely fast and modern vulnerability detection**

> Sometimes, expensive products out there have slow detection systems that consume a lot of resources. We confidently make this statement and are willing to compare the sophistication of our product against others, because we have conducted comparative research and obtained proven results.

**`Designed for extremely fast detection and high stability, advanced algorithms to adapt to modern vulnerabilities and tested intently and measurably.`**

#### Launch speed testing

**Results will vary depending on device specifications!**

**3. Less RAM Consumption**

Rich in features but still runs efficiently with minimal RAM usage without overhead and memory leaks.

#### Memory usage comparison

Comparison of memory usage on protected apk and unprotected apk

| Protected APK With Garuda Defender |
| :--------------------------------------------: |
| <img src="img/wpro.gif" style="width: 600px;"> |

**Results will vary depending on device specifications!**

**`Testing carried out in debug mode in theory at release should be lower than the results in the video.`**

**4. Does not affect application performance**

We employ the most effective methods to maintain the performance of the application. This framework ensures that the application remains fast and preserves the speed of app launch.

> We don't use Shell/ClassLoader because we find it less efficient and it slows down the application launch. Decrypting and loading the dex files take up considerable time, which contributes to the delay. Another drawback is that shells can be easily repackaged.

In doing so, we opt for another approach to safeguard your Java source code, protecting it from the exposure of application business logic and the authenticity of its code.

**5. Friendly with other applications and piracy tools**

> Sometimes some security framework providers block piracy tools or applications to prevent unwanted things, of course this is not friendly in our opinion.

**`Therefore our goal is that all such tools will be useless for our framework, there is no need to blindly block other applications that are not desired.`**\

**6. No Developer Option Blocker**

> One of the funniest things is why block the developer options?

**`GarudaDefender will handle everything without restricting your usage policies or disrupting the user experience.`**

**7. No threats or viruses detected**

This framework does not cause false detection as a virus, of course this will increase the success rate of submitting applications to the Playstore

**8. No special android permissions required**

You can analyze it yourself by opening AndroidManifest.xml, see uses-permission, there are no permissions used, So don't claim we are digging up your information!

## Limitations

- **At the moment, the framework only works for Android applications.**

## Lessons

Of course we are aware and care about the security, authenticity, robustness in our systems, so we continue to maintain and research modern vulnerabilities to continue to maintain our security. Carrying out rigorous analysis and testing from various angles to provide the best service for our users.
