![]() The criteria for the baseline are based on what the average chat platform has to offer. All these platforms have a security/privacy focus (or at least had this focus in the past). The platforms that I have chosen to compare are Keybase, Matrix (Element), WhatsApp and Signal. ![]() ![]() We also take a look at what the platform is allowed to do with your dataĮach rating will be assigned one of the following scores: terrible, bad, neutral, good or excellent. Privacy Here we focus on how much of your personal data you need to supply to the platform in order to participate.Authentication is about proving that you are the owner of a particular account and user trust is about proving that a particular account belongs to you Users will need the ability to be sure that they are actually communicating with the right person. I have also sneaked user trust in here because it is heavily related to authentication. Strong authentication controls make it difficult for attackers to impersonate others and gain access to conversation history. Authentication and Trust Indicates how well the platform authenticates its users.Here we will determine how good a chat platform is in keeping chat records complete and available Integrity and Availability I have combined these two into one rating.Chat messages should only be accessible to those who are part of the conversation Confidentially Indicates how good the chat platform is in keeping things secret.The A stands for Authentication and the P stands for Privacy. I would like to base the ratings on the CIA triad, but I will add the letters ‘A’ and ‘P’. I will obviously use this opportunity to praise my two favorite platforms and hate on the two I am forced to use. I will promise that this will be an honest comparison without any bias towards any of them … Ah, who am I kidding. I have picked four platforms that I will compare to each other. I will be focusing on the more security-focused chat platforms. Teams targets business users while Telegram has become more of a social media. Different chat platforms target different audiences. Chatting with yourself is not a lot of fun after all. I have experimented with many chat platforms throughout the years but always had to put in a great amount of effort to persuade others to make the switch. I had a pre-paid SIM card and sending an SMS was still quite expensive back then. It was the first time I could send messages from my phone without worrying about costs. I got introduced to WhatsApp when I got my first smartphone which was a Samsung Galaxy Gio. ![]() The first platform that I actually used was Skype (I know it’s more of a video conferencing platform, but it also has chat functionality). ![]() I was told that it was cheaper to use BBM than to send messages over SMS.Īlthough I never used BBM personally, it was the first time I came into contact with a chat platform. All the cool kids in my class had these BlackBerry devices and they used an application called BlackBerry Messenger (BBM) to send messages to each other. It was just for contacting my parents in case of emergencies. I can still remember a time when I was in school and carried around a Sony Ericsson J110 dumb phone. As already mentioned in the previous post, this one will be about chat platforms. Hello and welcome to a new blog post in the OpSec blog series. ![]()
