Stop Zoombombing: How to Secure Your Video Calls for Work and Family

The rapid shift to remote work and virtual socializing transformed video conferencing from a niche business tool into a daily necessity. Platforms like Zoom, Microsoft Teams, Google Meet, and others became our boardrooms, classrooms, and family living rooms. But this convenience came with a vulnerability. As we opened our digital doors to colleagues, clients, and loved ones, we also inadvertently created an opportunity for a new form of digital trespassing: Zoombombing.

Zoombombing is the malicious, unsolicited intrusion into a video conference by an individual or group, typically with the intent to disrupt. What begins as a productive meeting or a joyful family catch-up can, in an instant, be shattered by the intrusion of shocking imagery, hate speech, or other offensive content. This isn’t just a minor nuisance; it’s a violation of privacy that can cause significant distress, compromise sensitive information, and damage professional reputations.

The good news is that Zoombombing is almost entirely preventable. The vast majority of these incidents occur not due to sophisticated hacking, but because of overlooked or misunderstood security settings. By understanding the tools at your disposal and adopting a security-minded approach, you can reclaim your virtual space.

This guide draws on best practices from cybersecurity experts, the official documentation of major platforms, and real-world experience in corporate and personal IT management. Whether you’re a team leader responsible for confidential corporate strategy sessions, a teacher connecting with a classroom of students, or a grandparent hosting a weekly family trivia night, this article will equip you with the knowledge to secure your calls with confidence.

Part 1: Understanding the Threat – It’s Not Just “Zoom”

While the term “Zoombombing” specifically names the platform that skyrocketed in popularity during the pandemic, the vulnerability is platform-agnostic. Any video conferencing tool can be targeted if not configured correctly. The core of the problem lies in how meeting links and access credentials are generated and shared.

How Do Intruders Find Your Meetings?

Disruptors don’t need advanced technical skills. They typically find targets through:

Publicly Posted Links: The most common vector. When meeting links are posted on public social media profiles, open forums, or unsecured websites, they are easily discoverable by web crawlers and malicious individuals scanning for open meetings.
“Leaked” Links: A participant might inadvertently share a meeting link in a public space, or it might be forwarded to someone outside the intended group without the host’s knowledge.
Simple Guessing: Some platforms generate Meeting IDs sequentially or using predictable patterns. While less common now, it was an initial vulnerability.
Insider “Pranks”: Sometimes, the disruption comes from a known participant who shares access with an outsider for a “joke.”

The Impact of a Breach

The consequences extend far beyond a momentary interruption.

For Businesses: Disclosure of proprietary information, loss of client trust, legal ramifications (especially under data protection laws like GDPR or HIPAA), and a severe blow to professional credibility.
For Educators and Students: A disrupted learning environment, exposure of minors to harmful content, and a chilling effect on participation.
For Families and Friends: A violation of personal and private moments, causing emotional distress and making vulnerable family members feel unsafe in a space that should be secure.

Understanding that the threat is real and the methods are simple is the first step toward prevention. The solution is proactive security.

Part 2: The Ultimate Pre-Meeting Checklist: Locking the Door Before Anyone Arrives

Security begins long before you hit the “Start Meeting” button. By configuring your settings correctly during the scheduling phase, you can build a formidable first line of defense.

1. The Golden Rule: Never Use Your Personal Meeting ID (PMI) for Public or Group Events

What it is: Your PMI is a permanent, dedicated virtual room for you on platforms like Zoom. It’s like your personal office or living room number.
The Risk: If you use your PMI for a public event and it gets bombed, that same ID is compromised forever. Intruders who saved it can attempt to re-enter any time you use it.
The Solution: Always disable the “Use Personal Meeting ID” option when scheduling a new meeting. Let the system generate a unique, random Meeting ID for each session. This is the single most important step in securing your calls. Reserve your PMI for one-on-one calls or with a very small, trusted group who understands it’s your permanent link.

2. Require a Meeting Password

This is a fundamental access control layer. Even if someone obtains your Meeting ID, they cannot enter without the password.

How to Implement:
- Zoom: The password option is now enabled by default. When scheduling, ensure “Require meeting password” is checked. You can then share the password separately from the link.
- Microsoft Teams: Teams meetings automatically have a complex password integrated for participants joining via phone, and the link itself is a complex, unique credential.
- Google Meet: Links are inherently complex and difficult to guess, acting as a de facto password.
Best Practice: When sharing the invitation, consider sending the link and the password through different channels (e.g., link in the calendar invite, password sent via a secure messaging app like Signal or in the email body, but not in the same line as the link).

3. Enable the “Waiting Room” Feature – Your Virtual Bouncer

The Waiting Room is arguably the most powerful security feature available to hosts. It gives you ultimate control over who enters the meeting.

What it is: When participants join, they are placed in a virtual holding area. The host must manually admit each person one by one or all at once.
Why it’s Essential: It allows you to visually screen every participant before granting them access. You can see their display name and, if you recognize them, admit them. If an unknown name appears, you can keep them in the Waiting Room or remove them.
How to Use it Effectively:
- For Work: Instruct participants to use their full names as their display name. This makes identification easy.
- For Family: Ask family members to use a name you would recognize (e.g., “Aunt Susan”).
- For Public Webinars: Use the Waiting Room in conjunction with registration (see below) to manage the flow of a large number of attendees.

4. Disable “Join Before Host”

This setting ensures the meeting cannot start without you. It prevents a scenario where participants are left in an unsecured, unmoderated room waiting for you to arrive.

The Logic: With this disabled, if anyone clicks the link early, they will see a message that the host has not yet started the meeting. This guarantees that you are present from the very first moment a participant joins, allowing you to manage the Waiting Room and maintain control.

5. For Public or Large Meetings, Use Registration

If you are hosting a webinar, a public talk, or any event where you expect attendees you don’t personally know, the Registration feature is indispensable.

How it Works: Instead of sharing a direct meeting link, you share a registration page. Participants must provide their name and email address to receive the unique link to join.
Benefits:
- It gives you a list of everyone who intended to join.
- It automatically sends a unique, traceable link to each registrant. If a meeting is disrupted, you can identify which link was compromised and take action against that specific registrant.
- It acts as a minor barrier that discourages casual trolls.

6. Control Screen Sharing: The “Mute” Button for Visuals

Unrestricted screen sharing is a primary tool for disruptors. The moment they gain access, they can share their screen and display offensive content to everyone.

The Secure Setting: Change the screen sharing permissions to “Host Only” by default. This is a critical configuration.
Managing Participation: If a legitimate participant needs to share, you can promote them to co-host during the meeting, or (on platforms like Zoom) change the setting in-meeting to “All Participants” temporarily and then change it back. Better yet, use the “Allow Participant to Share” option that lets you grant permission to one specific person without changing the global setting.

Part 3: In-Meeting Management: Taking Command of the Virtual Room

Your preparation pays off once the meeting begins. As the host, you have a suite of real-time tools to maintain order and security.

1. The Role of the Co-Host

For larger meetings, you shouldn’t have to manage security alone. Designate a trusted colleague, assistant, or family member as a co-host.

Co-Host Capabilities: A co-host can help you manage the Waiting Room, monitor the participant list, mute attendees, and remove disruptive participants. This is especially useful if you are the main presenter and need to focus on content.
How to Assign: In the Participants panel, hover over a participant’s name and select the option to “Make Co-Host.”

2. Mastering the Participants Panel

This is your mission control during the call. Keep it open and monitor it periodically.

Mute All: You can mute all participants upon entry and disable their ability to unmute themselves. This prevents audio disruptions, coughing, background noise, and unwanted comments. Participants can use the “Raise Hand” feature to request to speak.
Remove a Participant: If someone is disruptive, you don’t just want to mute them—you want them out. Hover over their name in the Participants list and click “Remove.” Crucially, also check the box that says “Block this user from rejoining.” This prevents them from simply using the same link to come right back in.
Lock the Meeting: Once all expected participants have arrived, lock the meeting. This is like closing and locking your front door. Even someone with the correct link and password will be unable to enter. You can always unlock it if someone gets disconnected and needs to rejoin.

3. Managing Chat and Reactions

The chat function can be another vector for disruption via text or link sharing.

Control Permissions: You can restrict the chat so that participants can only send messages to the host (or to no one at all), preventing public spam.
Disable File Transfer: Ensure participants cannot share files through the chat, as these could contain malware.
Manage Annotations and Whiteboards: For highly sensitive meetings, consider disabling the annotation feature to prevent unwanted drawing on shared content.

Part 4: Platform-Specific Security Settings Deep Dive

While the principles are universal, the location of these settings varies. Here’s a concise guide for the major platforms.

Securing Your Zoom Meetings

Zoom, after early controversies, has made security a priority and often enables these features by default. Always verify your settings at zoom.us/profile/setting.

Schedule a New Meeting:
- Uncheck “Use Personal Meeting ID (PMI).”
- Check “Require a password.”
- Check “Enable Waiting Room.” (Consider using the “Enhanced” option to send authenticated users and those not signed in to different holding areas).
- Set “Video” for Host and Participant to “Off” for a more controlled start.
- Set “Audio” for Participants to “Telephone and Computer Audio” or “Computer Audio” to prevent random phone numbers from joining.
In-Meeting (Host) Controls:
- Security Button: The shield icon in the meeting controls is your quick-access security hub. From here, you can instantly lock the meeting, enable the Waiting Room, and control participants’ ability to share screen, chat, and rename themselves.
- Participants Panel: Use “Mute All,” “Remove,” and “More” options to manage attendees.

Securing Your Microsoft Teams Meetings

Teams is deeply integrated with the Microsoft 365 ecosystem, and its security is robust by design.

Scheduling in Outlook or Teams Calendar:
- When sending an invitation, use the dropdown to control who can bypass the lobby: “People in my organization” or “Only me and the co-organizers.” “Everyone” should be used sparingly.
- The meeting link is inherently secure and long.
In-Meeting Controls:
- Click on the Participants icon to see the “Meeting options” pop-out. This is a powerful panel where you can set who can present (limit this to “Specific people” or “Only me”), control who can unmute, and decide if attendees can start video.
- Use the “Lobby” feature effectively to hold unknown participants.

Securing Your Google Meet Meetings

Google Meet benefits from its integration with Google Workspace, and its links are notoriously hard to guess.

Scheduling in Google Calendar:
- The “Add Google Meet video conferencing” option generates a unique link.
- For added security within an organization, you can change the setting to “Only allow guests to join if they are from the same organization.”
In-Meeting Controls:
- Hosts have a “Quick access” setting. Turning this off acts like a Waiting Room, requiring the host to admit each participant.
- Use the “People” tab to remove participants or limit their ability to share their screen (by changing the “Host controls” in settings).

Part 5: Special Considerations for Different Audiences

A one-size-fits-all approach doesn’t work. Here’s how to tailor your security for different contexts.

For Businesses and Corporate Users

Mandatory Authentication: Require participants to be signed into their corporate account (e.g., their company Zoom or Teams account) to join. This prevents anonymous entry entirely.
Endpoint Security: Ensure all employee devices have updated antivirus software and that the video conferencing app is always updated to the latest version to patch security vulnerabilities.
Data Privacy: For highly sensitive discussions, consider platforms that offer end-to-end encryption (E2EE). Be aware that E2EE often disables certain features like cloud recording and joining via phone.
Employee Training: This is crucial. A single employee using an insecure setting can compromise the entire organization’s security posture. Conduct regular training sessions on these best practices.

For Educators and Schools

Protecting Minors: Security is paramount. Always use Waiting Rooms and require passwords. Never post meeting links on public-facing school websites.
Platform Choice: Use education-specific platforms like Google Classroom or Zoom for Education, which provide teachers with enhanced controls and are compliant with student privacy laws like FERPA.
Set Clear Expectations: Establish and communicate virtual classroom rules with students and parents about behavior, display names, and when it’s appropriate to use video, audio, and chat.
Leverage Co-Hosts: If possible, have a teaching assistant or another teacher act as a co-host to manage technical and security issues, allowing the instructor to focus on teaching.

For Families and Social Calls

Keep it Simple: The basics are often enough. A unique meeting link, a simple password (e.g., “Grandma2024”), and a Waiting Room are your best friends.
Pre-Call Briefing: For less tech-savvy family members, a quick phone call before the first video call to walk them through the process of using the password and waiting in the “lobby” can prevent frustration.
The “No Public Posts” Rule: Make it a family rule that video call links are never to be posted on social media, even in a “fun” way. Share them via private email, text, or family messaging groups.

Part 6: Beyond the Platform – Cultivating a Culture of Security

Technology is only half the solution. The most secure settings can be undone by human error.

Be Skeptical of Links: Just as with phishing emails, be cautious about clicking on video call links from unknown senders. Verify the source.
Keep Software Updated: Video conferencing apps release frequent updates that often include critical security patches. Enable automatic updates or make a habit of checking for them monthly.
The Principle of Least Privilege: In a professional context, only grant host and co-host privileges to those who truly need them. Only allow screen sharing when it’s necessary for the agenda.
Have a Plan: What will you do if a meeting is disrupted? A prepared host can act swiftly and calmly. The steps are: 1) Stay Calm. 2) Mute the Participant. 3) Stop their Video. 4) Remove the Participant. 5) Lock the Meeting. 6) Check in with your attendees to ensure everyone is okay before continuing.

Conclusion: Your Virtual Space, Your Rules

Zoombombing is a disruptive and violating act, but it is not an inevitability. It is a preventable consequence of misconfigured software. By embracing your role as the host and taking proactive ownership of your meeting’s security, you transform your virtual room from a vulnerable, open door into a fortified, controlled environment.

The steps outlined in this guide—from leveraging the Waiting Room and passwords to managing in-meeting permissions and cultivating security awareness—are your blueprint for safety. They empower you to connect with colleagues, students, and family with the confidence that your space is secure. The responsibility is real, but the tools are powerful and, most importantly, effective.

Stop reacting to disruptions. Start preventing them. Implement these strategies today and take back control of your video calls.

Frequently Asked Questions (FAQ)

Q1: I’ve been Zoombombed before. What should I do right after it happens?
A: Act quickly and calmly.

Remove the intruder: Use the “Remove” function and check “Block user from rejoining.”
Lock the meeting: Prevent anyone else from joining.
Pause the meeting: Briefly stop to address the situation. Acknowledge the disruption, check if attendees are okay, and reassure them that the intruder has been removed.
Report it: On platforms like Zoom, you can report the user to their Trust and Safety team. In a corporate or school setting, report the incident to your IT or security department.

Q2: Is one platform more secure than the others?
A: All major platforms (Zoom, Microsoft Teams, Google Meet, Webex, etc.) are highly secure when configured correctly. The biggest differentiator is not the platform itself, but the host’s knowledge of its security settings. Zoom offers very granular, user-friendly controls. Teams and Meet benefit from deep integration with their respective corporate/education ecosystems, making authentication easier. The “most secure” platform is the one whose security features you know how to use effectively.

Q3: What’s the difference between a Waiting Room and requiring registration?
A: A Waiting Room is a real-time screening tool. Everyone who joins is held until the host manually admits them. It’s ideal for meetings where you know the participants or can recognize their names.
Registration is a pre-meeting screening tool. It collects information from attendees before they even get the link. It’s ideal for public webinars, large events, or any situation where you need a list of attendees and want to deter casual trolls with a registration barrier.

Q4: I’m not the host, just a participant. What can I do to help keep a call secure?
A: Participants play a crucial role!

Protect the link: Treat the meeting link and password as confidential. Don’t forward it without the host’s permission.
Use a recognizable name: Join with your first and last name (for work) or a name the host will know (for family).
Report issues: Use the in-meeting “Report” feature or privately message the host via chat if you see something suspicious or disruptive.
Be patient in the Waiting Room: Understand that the host is using it for everyone’s security.

Q5: Are video calls encrypted? Should I be worried about someone eavesdropping?
A: All major video conferencing providers use encryption for data in transit (TLS), which protects your call from being intercepted by outsiders as it travels over the internet. Some, like Zoom and WhatsApp, offer an optional end-to-end encryption (E2EE) mode. E2EE means that no one, not even the platform company, can decrypt the call data. However, E2EE often comes with trade-offs, like the inability to join by phone, use cloud recording, or have the host use certain features. For most business and personal calls, the standard encryption is very robust and sufficient. E2EE is typically reserved for discussions involving the highest levels of commercial or state secrecy.

Q6: My company uses a platform I’m not familiar with. How can I learn its security features?
A: The best course of action is to:

Contact your IT department. They are the experts on the platform your organization has chosen and should provide training and documentation.
Search the platform’s official help center. Look for articles with keywords like “security,” “meeting controls,” “host controls,” “lobby,” and “permissions.”
Do a test meeting with a colleague. Explore the settings as both a host and a participant to understand the interface and capabilities in a risk-free environment.
