Since the start of the COVID-19 pandemic, the Zoom videoconferencing service has enjoyed phenomenal success. According to the company, the number of people participating in video calls on the platform increased from 10 million per day in December 2019 to 200 million per day in March 2020.

Its free and easy to use have contributed a lot to its success. However, in recent weeks, computer security experts have exposed a long series of flaws in the service.

As some URLs for attending Zoom meetings are public, strangers may come in to disrupt these events, for example by broadcasting pornography, a practice known as zoombombing.

Also, while Zoom claims to use AES-256 end-to-end encryption – deemed very secure – to protect the privacy of participants, the Citizen Lab in Toronto has shown that it uses the AES-128 encryption in ECB mode – deemed much weaker. In addition, some calls transit through China, known for its espionage operations.

Faced with these revelations, Zoom claims to have stopped all new development of its platform for 90 days in order to concentrate its efforts to resolve its security and privacy issues.

Are you looking for a free alternative? You will find some of them below. But if you prefer to continue using the Zoom platform, you can do so more securely by making a few settings, including adding a password required to access a meeting. On this subject, see these tips from the University of Montreal (PDF).

FaceTime

Maximum of participants: 32

Developed by Apple and offered only on its devices (iPhone, iPad, Mac computers, etc.), FaceTime protects calls with AES-256 encryption from start to finish. Apple has a good reputation for privacy, especially since its business model is not based on data collection and advertising. However, FaceTime does not offer some very useful features, such as sharing presentations.
