Monitor suspicious activity in your Dart application

LogSnag makes it easy to monitor your Dart service and track when suspicious activity is occurring.

When building a Dart application that you plan to release to the public, or even if you're building a private application, as developers, we are always looking for ways to make sure that our application is secure and that it's not being misused.

The misuse of our application can be in the form of a user trying to access data they shouldn't have access to or a user trying to perform an action they shouldn't be able to achieve. This can be a severe problem and can lead to many issues such as data loss, data corruption, or even data theft.

Thus, it's essential to set up a system to monitor suspicious activity in your Dart application properly and let you and your team know when something is wrong.

For example, let's say you're building a Dart application that allows users to upload files. One of the common concerns with this type of application is that users may try to take advantage of your service and upload files that they shouldn't be able to upload, such as illegal content, huge files, or even malware.

LogSnag is an excellent tool for this problem as it trivializes tracking events in your Dart application and suspicious monitoring activity. For example, you can use LogSnag to track an event when a user uploads a file. You can then set up a rule to notify you when a user uploads a file that is larger than 100MB. This way, you will know when a user is trying to upload a too large file, and you can take further action if needed.
