Video conferencing solution with a threat protection system

They Trust Us

TrueConf solutions are used by hundreds of thousands of organizations worldwide. Among them are governments, private and public companies, banks, courts, clinics, and educational institutions.

Types of Video Conferencing Encryption

TLS

TLS (Transport Layer Security) is a cryptographic protocol that provides communication security and privacy over the Internet. It is used in applications such as web browsing, email, instant messaging, and VoIP (Voice over Internet Protocol).

SRTP

SRTP (Secure Real-time Transport Protocol) is a key component of secure voice and video communication, providing end-to-end security between two parties. It protects the confidentiality and integrity of voice and video data as it is transmitted over a network.

E2EE

E2EE (End-to-End Encryption) is a security system in which all data remains encrypted from the moment it is created until it is destroyed. If someone intercepts the data while it is in transit, they will not be able to read it without the proper encryption key. When looking for a video conferencing solution, be sure to ask if it offers end-to-end encryption. The above types of security measures are essential for any business or organization that wants to keep its data private. This is especially important for online meetings, which often involve the exchange of sensitive information.

Full Control Over Communications

TrueConf Server is deployed on your company's equipment and works autonomously inside a closed corporate network, which guarantees reliable protection of personal data from third parties.

Full Control Over Communications

Legitimate Security

Video conferencing security is not only recommended for business communications: it is the law. Recent government regulations, such as the Health Insurance Portability and Accountability Act (HIPAA) and the General Data Protection Regulation (GDPR), require medical service providers, financial institutions, and other companies to protect all electronic data related to their clients and patients. That includes all electronic transmissions of customers' personal data, including video conferences.

Google Meet

Google Meet (Hangouts)

Google Meet is a secure cloud-based solution that allows users to organize both individual and group video conferences. The platform offers many opportunities for collaboration, such as the well-known Jumpboard. Google Meet allows even unregistered guests to join the conference using the meeting code.

Security

Google initially created the solution as a business tool in the Google Workspace suite, but eventually made it available for non-commercial use. To protect personal data, the online meeting platform adheres to TLS and SSL standards for encryption during data transmission. Registered users can enable two-factor authentication using FIDO-compatible text messages, authentication apps, or security keys.

Vulnerabilities

Google Meet does not support end-to-end encryption: instead, it uses DTLS-S to protect connections. However, some may find it unpleasant to discover that the solution's vendor stores data on delays and performance. Such «collectible» information includes the data transfer rate, estimated bandwidth, names of conference organizers, participant IDs, IP addresses, as well as the meeting's date and calendar ID.

Security researchers recently highlighted a vulnerability in Google Meet's URL redirection feature, which could lead users to counterfeit domains and make them vulnerable to cybercriminals. Furthermore, when joining a meeting from a smartphone, the audio transmits over the telephone network and may not be encrypted.

Slack

Slack

Slack is a corporate messaging platform that supports video chats for up to 15 users. This solution, like other vendor services, requires mandatory account login and uses a secure system to protect confidential data. Slack supports integration with nearly 100 third-party services, including Dropbox, Google Drive, and Twitter, which explains its versatility.

Security

Data transfer between the messenger and the service uses reliable encryption protocols and signatures, such as TLS 1.2, AES-256, and SHA2. Notably, this protection system only works with the user's consent, who must approve the processing of their personal information. Confidential data at rest in the Slack production network is encrypted according to FIPS 140-2 standards, including relational databases and file storage. Simultaneously, all encryption keys are stored on a secure server with restricted access.

Vulnerabilities

If you plan to use Slack for business purposes, you should be aware of the associated risks. In 2015, hackers breached Slack, exposing vulnerabilities in the messenger's security system. The company announced that hackers had breached its system, gaining access to the database for four days and jeopardizing user privacy.

After the cyberattack, Slack experts discovered suspicious activity from several accounts that had clearly been compromised by criminals. In 2019, Tenable specialists discovered a vulnerability in the Windows version of Slack. The client application allowed users to change the download destination, potentially enabling them to steal, modify, or add malware to files.

The critical vulnerability also allowed for remote code execution (RCE). Hackers could gain full remote control over the Slack desktop application through a successful exploit, thereby accessing private channels, conversations, passwords, tokens, and keys.

Skype

Skype

Skype, created by Microsoft, is a free software for making video calls. The «‎Meet Now»‎ option allows presenters to invite both registered participants and anyone else to a virtual meeting, without requiring an account. Regarding commercial purposes, it is worth noting that Skype for Business will cease operations on July 31, 2021.

Security

Skype uses AES, also known as Rijndael, which the US government employs to safeguard confidential information. At the same time, the encryption itself is 256-bit and has proven to be reliable. Skype server uses 1536- or 2048-bit RSA certificates to certify users' public keys.

Vulnerabilities

By default, Skype does not use end-to-end encryption, which means Microsoft can view all messages, calls, and files. In addition, the vendor records people's interactions on their platform, including, but not limited to:

  • Chat history
  • Activity status
  • Telephone numbers
  • Files sent and received
  • Time and duration of calls

Microsoft claims that it also collects user data from third parties, including data brokers. The corporation uses personal information for targeted advertising, personalization, research and development, and product improvement. Microsoft shares personal data with its affiliates, subsidiaries, and suppliers.

Cisco Webex

Cisco Webex

WebEx, the video conferencing platform, has existed since 1995 and is widely used by privacy-conscious companies in the healthcare, information technology, and financial services industries. This is partly because all three sectors had adopted virtual meetings long before the COVID-19 pandemic, but mostly due to the solution's reputation for maintaining strong cybersecurity. Cisco, WebEx's parent company, has long established itself as a reliable and secure vendor for corporate interactions.

Security

By default, WebEx makes user data readable by the server, but it also offers additional end-to-end encryption for up to 200 users, which exceeds the capacity of many competitors. Free account holders can contact customer support for additional protection measures. Despite considering the possibility of hosting an on-premises solution, the vendor offers a Cisco Meeting Server for this purpose.

Vulnerabilities

In 2020, Cisco engineers prepared fixes for three vulnerabilities that hackers could exploit during WebEx conferences. IBM discovered security breaches that allowed attackers to join online meetings as ghost users and gain access to personal data. Therefore, a cybercriminal could discover the full names, email addresses, and IP addresses of conference participants.

WhatsApp

WhatsApp

It is highly likely that you have friends or relatives on WhatsApp, as this messenger already has over two billion users. The solution was created in 2009, but it reached peak popularity in 2015, even becoming the primary means of communication in several countries, particularly in Latin America. WhatsApp enables users to organize personal and group chats, make audio and video calls, share files and locations, and even create polls.

Security

To ensure privacy, the solution supports end-to-end encryption, preventing even company employees from viewing your messages or listening to conversations. WhatsApp allows users to enable two-step verification to further protect their personal data and send disappearing messages.

Vulnerabilities

In January 2021, Meta announced an update to its privacy policy, stating that WhatsApp would store personal metadata and share it with Facebook and its «family of companies» (including Facebook Messenger, Instagram) starting in February of that year. Users could previously refuse to transfer information in the settings, but this feature is no longer available. Cyber awareness is something you need to keep in mind at all times while using WhatsApp.

In 2022, the leak resulted in the release of nearly 500 million users' personal data onto the internet. Meta had been storing users' confidential information in a nearly unencrypted form for years, allowing hackers to easily bypass the security system and gain access to it. In the following years, residents of 84 countries, including the United States, Italy, and France, suffered from the actions of fraudsters and criminals.

Zoom

Zoom

Zoom is a video communication platform that offers a wide range of collaborative tools. The solution gained the most popularity in 2020 during the pandemic, as many companies and organizations adopted it for remote work. Many enterprises continued using Zoom even after the lockdown was lifted, demonstrating its ongoing high demand.

Security

When using a Zoom client, video, audio, and screen sharing are protected in transit with AES-256 encryption and a one-time key for that specific session. To further protect your privacy, the solution enables additional end-to-end encryption.

Vulnerabilities

«Zoombombing» remains a significant stain on the company's reputation regarding security. The occurrence of intruders appearing in conferences and subsequently using profanity has become one of the most significant hacker attacks in the history of video communication. Attackers could send, edit, and remove chat messages, as well as remove other participants from online meetings.

FAQ

What is video-conferencing security, and why is it important?

Video-conferencing security involves practices and systems implemented to defend digital meetings, video sessions, and collaborative content against illicit intrusion, data leakage, and cyber vulnerabilities. This includes safeguarding audio and video transmission through encryption, deploying verified login protocols, enforcing permission controls, ensuring encrypted content storage, and using detection tools to identify irregular actions. Strong video conferencing security plays a vital role in protecting confidential materials, particularly within sectors such as healthcare, finance, public services, and academia.

Lack of adequate protections can leave online meetings open to threats like unauthorized listening, session interruptions (often called “Zoom-bombing”), information exposure, and regulatory breaches. Establishing effective video-conferencing safeguards enhances credibility, secures both individual and corporate assets, and assists organizations in meeting compliance standards including HIPAA and GDPR. In modern distributed or hybrid work environments, maintaining protected video interaction is a foundational aspect of enterprise cybersecurity planning.

Key features of secure video-conferencing solutions

End-to-End Encryption

End-to-end protection guarantees that communication shared throughout a conference—like visuals, sound, messaging, and documents—is completely shielded between originator and recipient. This ensures that neither external providers nor unintended recipients gain visibility into confidential content. It blocks unauthorized viewers from capturing or exploiting sensitive transmissions. Such encryption remains vital for sectors including healthcare, financial services, and law, where information secrecy is paramount.

Password-Protected Meetings

Using entry passwords for sessions introduces a fundamental yet effective barrier to unwanted access. It verifies that attendees with accurate identification details are the only ones admitted into digital discussions. This deters intrusions and reduces risks of session hijacking or disruptions. Distributing strong and private credentials securely is an essential part of this practice.

User Authentication & Multi-Factor Authentication (MFA)

User verification confirms identities by applying login credentials, while MFA enhances this by requesting an additional layer—such as temporary codes or biometric input. These combined steps significantly lower the chance of security breaches, even when passwords are exposed. Adding MFA bolsters the protection of remote meetings. It's particularly critical in institutions managing private, protected, or regulated records.

Waiting Rooms & Host Controls

Waiting rooms give meeting organizers the authority to validate attendees before granting access. Organizers can secure sessions by enabling locks, silencing users, controlling screenshare rights, and disabling chats if necessary. These proactive features prevent accidental interruptions and block uninvited joiners. Hosts maintain control throughout the session, ensuring a secure and orderly environment.

Encrypted Recording & Storage

When capturing a virtual meeting, it's necessary to apply encryption during both saving and retrieval processes. This approach prevents unauthorized access and ensures integrity of archived materials. Storage tools should adhere to strict privacy frameworks like HIPAA and GDPR. Recorded content must also reside in restricted environments with thorough access documentation.

Regulatory Compliance (HIPAA, GDPR, etc.)

Trusted video-conferencing tools are expected to align with legal data protection frameworks such as HIPAA for health or GDPR in the EU. Such compliance confirms that proper defenses are in place to protect sensitive and personal data. Failing to meet these standards could lead to data compromise or fines. Selecting a compliant solution affirms an organization’s dedication to privacy obligations.

Audit Logs & Activity Monitoring

Audit functions document interactions—logins, file transfers, and meeting behavior—for each participant. This visibility allows for the identification of anomalies and supports regulatory reporting. These records are key for investigating breaches or tracing suspicious activity. Regular oversight of such logs enhances transparency and mitigates potential internal or external misuse.

Tips for secure video conferencing

Choose a Secure, Trusted Platform

Select a video conferencing solution that offers end-to-end encryption, secure authentication, and compliance with industry standards like HIPAA, GDPR, or ISO/IEC 27001. Platforms with strong reputations and transparent privacy policies are less likely to expose your data. Avoid using consumer-grade tools for sensitive business or healthcare communication. Always verify the platform’s security features before adoption.

Protect Meetings with Passwords and Waiting Rooms

Always enable meeting passwords and activate waiting rooms to prevent unauthorized access. Waiting rooms allow hosts to manually admit participants, adding an extra layer of control. This helps defend against "Zoom-bombing" or uninvited users disrupting the call. Secure entry measures are essential for both small team meetings and large webinars.

Restrict Screen Sharing and Recording

Limit screen sharing to hosts or specific users to reduce the risk of accidental data leaks. If you must record meetings, notify participants and ensure recordings are encrypted and securely stored. Only authorized personnel should have access to these files. Disabling recording by default is a good practice unless necessary for compliance or documentation.

Use Multi-Factor Authentication (MFA)

Enable MFA for all users to protect accounts from unauthorized access, even if passwords are compromised. MFA requires a second layer of verification—such as a text message code or authentication app. This greatly reduces the chance of breaches caused by phishing or weak passwords. It’s a critical step for securing both user identities and sensitive meeting data.

Keep Software and Devices Updated

Always run the latest version of your video conferencing software to patch known security vulnerabilities. Updates often include critical fixes for bugs or flaws that could be exploited. Encourage users to install updates promptly and only download software from official sources. Keeping devices secure ensures the integrity of the conferencing environment.

Control Participant Permissions and Roles

Assign roles like host, co-host, and participant carefully to manage access and actions during meetings. Limit who can present, record, or invite others to reduce the chance of misuse. Use administrative settings to disable features like file transfer or chat when unnecessary. Clearly defined roles help maintain order and protect sensitive information.

Avoid Public Sharing of Meeting Links

Never post video conferencing links on public platforms such as social media or open websites. Public links can be picked up by bots or bad actors looking to disrupt meetings or steal information. Instead, send invitations through secure, direct channels like email or internal calendars. Treat meeting links as confidential access credentials.
