The Importance of Secure Video Communication

Calling someone over an unsecured video stream poses more risk than details of your personal conversations becoming public. The importance of a regulated video calling app can not be overstated, as an app that is not secure can result in one or more of the following: 

  • Data Breaches: Unsecured video calling apps are vulnerable to data breaches, which could expose users' personal information to those with malicious intent. Bad actors can use this stolen information for identity theft or financial fraud.

  • Unauthorized Access: Without preventative safety measures in place, your video calling app could allow hackers to join your video calls without authorization and access private conversations and data.

  • Cyberbullying and Doxing: Bullies and stalkers trying to harass and intimidate others can easily circumvent unsecured apps. Just as a malicious user can leverage private information for personal gains, like financial fraud, they can also post it online, where others can view and misuse it.

Security Features of the Safest Apps

With the importance of a secure video connection being clear, let's take a look at the top safety features to consider before downloading your next app: 

  • End-to-End Encryption: Encryption protects communication between users on a video call and prevents unauthorized access to data transmissions.

  • Access controls: In-app access controls enable users to determine who can join a video call and access certain features, like screen sharing or file sharing.

  • User Authentication: To prevent unauthorized access, secure video calling apps require users to authenticate their identity with a code or from another device before joining.

  • Privacy Settings: Users can customize their privacy settings in a safe video chat app to limit or control who can see their profile, online status, location, and contact information.

  • Regular Security Updates: To stay up to date on the latest virus and hacking methodologies, secure apps implement new security standards regularly to prevent attacks.

  • Third-Party Audits: Security audits performed by an outside party ensure that the app meets industry standards and can help identify potential vulnerabilities.

  • Transparent Privacy Policies: Secure calling apps have clear and accessible privacy policies that outline how user data is collected, used, and shared.

Is Secure Video Calling Regulated?

There are several regulations that a video calling app may need to comply with to be considered secure, depending on the country or region in which it is used. They include: 

  • The General Data Protection Regulation (GDPR): This European Union regulation sets strict rules for the collection, use, and storage of personal data. A video calling app used in the European Union must achieve GDPR compliance to be considered secure.

  • The Health Insurance Portability and Accountability Act (HIPAA): This US federal law mandates the protection of personal health information for patients receiving care. If you are a healthcare provider seeing a patient over video for a telemedicine appointment, your video chat app must be HIPAA compliant to be legally used.

  • The Federal Information Security Management Act (FISMA): This federal law requires government agencies in the United States to develop, implement, and maintain security controls to protect sensitive or classified information. Government agencies that wish to conduct remote meetings over video calling apps must ensure their solution is FISMA compliant.

How to Be Sure Your Video Calling App is Secure

Whether you're simply catching up with a friend or discussing confidential business information with a colleague, you deserve to video call on the best app with confidence and know your personal data won't be compromised. If none of the options above suit your needs and you want to explore more options on your own, be sure to do your due diligence to review the app's privacy policy, encryption levels, compliance standards, access control options, authentication methods, and other security-minded features.
