7 Best Messaging Apps To Keep Your Conversations Secure And Private

Last Updated: September 29, 2016

Last year, we came across the fact that NSA collects almost 200 million text messages every day. That is when we realised that our privacy was indeed being invaded. The truth is, we live in an age of internet surveillance and data logging, where companies do almost anything to get our personal information. Thankfully, there has been a rise in secure messaging apps, which focus on keeping our privacy intact through end-to-end encryption and other ways.

Well, we explored various messaging apps that claim to be secure and found the best secure messaging apps among them. But first, let’s talk about why there’s a need for secure messaging apps.

Why we need secure messaging apps?

There are a number of reasons as to why we need secure messaging apps. In a test conducted by the Electronic Frontier Foundation, most of the popular messaging apps (BBM, Facebook Messenger, Hangout, Kik Messenger, Skype, Snapchat, Viber, WhatsApp, Yahoo Messenger) we use, failed to tick most security standards. This suggests that while these apps are great, the companies might be using our conversations as an information to target advertising in a better way. Moreover, reading our private conversations is certainly an invasion of our privacy.

Along with our personal privacy invasion, there are various industries where secure messaging apps are a must. Legal & Advisory firms need the best in class secure messaging apps because they wouldn’t want their client’s sensitive info to leak out. Health care is another industry where secure messaging apps is a must to protect patient information from leaking out to everyone. Finance, Banking and Insurance industries too need secure messaging apps because the information they share is very confidential indeed and they need to be sure about sending such sensitive information on an app.

These are surely good enough reasons to suggest that we indeed need secure messaging apps that give our privacy the priority. Thankfully, we have found some great secure messaging apps for you. Check them out:
