Who's listening to your meetings?

In 2023, Zoom quietly updated its terms of service to allow customer content — including audio and video from your meetings — to be used for AI training. The backlash was swift and loud. Within days, Zoom walked back the most explicit language and issued reassurances. But here's what didn't change: the architecture. Your audio, video, and chat still route through Zoom's servers, where Zoom retains the technical ability to access them. The policy changed. The infrastructure didn't.

For a corporate team discussing quarterly projections, this is an acceptable trade-off. For an organizer coordinating a rapid-response action, building out a coalition structure, or discussing anything that could attract legal scrutiny, it's a different calculation entirely. Platforms have terms of service that can change. They have legal obligations to respond to government requests. And under the US CLOUD Act, American companies can be compelled to hand over data stored on their servers — regardless of where those servers physically sit.

This article maps the major video conferencing platforms, what they actually do with your data, and how to choose the right tool for the right conversation.

Why "encrypted" doesn't always mean private

Most video platforms advertise encryption, and most of them are telling the truth — as far as it goes. The standard these platforms meet is encryption in transit: your data is scrambled as it travels between your device and their server. That protects against someone intercepting your traffic on the network.

It does not protect against the platform itself. Once your audio and video arrive at the server, the platform can access them. This is called server-side access, and it's the norm for Zoom, Google Meet, and Microsoft Teams.

The alternative is end-to-end encryption (E2EE): data is encrypted on your device and can only be decrypted by the other participants. The server is a relay, not a reader. Not every platform offers this, and not every platform that claims to offer it does so by default or for all call sizes.

That distinction — who can access your call content, and under what circumstances — is the thread that runs through everything that follows.

The platforms

Zoom

Zoom became the default meeting platform for a reason: it's polished, reliable, and nearly universal. For many organizing contexts, that familiarity is a genuine asset — lower friction means higher participation.

Free tier: Group meetings capped at 40 minutes; unlimited one-on-one calls. Up to 100 participants. No account required to join (only to host).

Paid: Pro plan starts at around $15.99/user/month and removes the time limit, raises participant caps, and adds cloud recording. Higher tiers add webinar features and larger participant counts.

Key features: Excellent breakout rooms, robust recording and transcription, strong webinar mode for large one-way presentations, wide device support, and near-universal familiarity among participants.

Privacy: Not end-to-end encrypted by default for group calls. Zoom's servers can access your meeting content. The 2023 terms-of-service controversy — where Zoom claimed broad rights to use customer content for AI training — was partially walked back, but the underlying server-access model remains unchanged. Zoom is a US company subject to the CLOUD Act.

Best for: Public-facing events, new volunteer orientation, large chapter calls where content isn't sensitive and participation rates matter most.

Google Meet

Google Meet's advantage is zero friction for anyone already in the Google ecosystem — which, for many organizers, means most of their participants. No download, no separate account, just a link.

Free tier: Up to 100 participants, with a 60-minute group call limit. Requires a Google account to host; guests can join without one via link.

Paid: Included in Google Workspace plans starting around $6/user/month, which removes time limits and adds recording, attendance tracking, and noise cancellation features.

Key features: Seamless Google Calendar integration, reliable browser-based performance, live captions, and compatibility with Google's broader collaboration tools (Docs, Slides, etc.).

Privacy: Not end-to-end encrypted. Google's servers can access meeting content, and Meet is part of the broader Google data ecosystem. If your organization is already Google-dependent, Meet doesn't add new exposure — but it doesn't improve your privacy posture either. US company, subject to CLOUD Act.

Best for: Routine coordination in organizations already on Google Workspace; meetings where content isn't sensitive and the convenience of Google Calendar integration is valuable.

Microsoft Teams

Teams is built for enterprise environments and shows it. If your organization lives in Microsoft 365, Teams is already there. If it doesn't, introducing Teams just for meetings adds overhead without corresponding benefit.

Free tier: Available with a Microsoft account; group call limit of 60 minutes. Up to 100 participants.

Paid: Included in Microsoft 365 plans from around $6/user/month, with higher tiers adding larger participant caps, recording, and advanced admin controls.

Key features: Deep Office 365 integration (SharePoint, OneDrive, Outlook), persistent channels for team communication, strong admin and compliance tools, good for large organizations with complex permission structures.

Privacy: Not end-to-end encrypted by default. Microsoft can access meeting content. US company, CLOUD Act applies. Microsoft has faced scrutiny over its AI Copilot features processing meeting transcripts, similar to the Zoom situation.

Best for: Organizations already running Microsoft 365 who need meeting capabilities integrated with their existing tools. Not worth adopting as a standalone meeting platform.

Jitsi Meet

Jitsi is the open-source alternative that's been a favorite among privacy-conscious organizations for years. It runs directly in a browser — no download, no account required to join — and the software itself is free and auditable.

Free tier: The public instance at meet.jit.si is completely free, with no time limits and no participant cap for basic use. Hosting on the public server requires a Google, GitHub, or Facebook account; joining requires nothing.

Paid: Jitsi as a Service (JaaS), a cloud-hosted version run by 8x8, starts at around $12/month for up to 20 participants and is designed for organizations that want managed hosting without running their own server.

Key features: Browser-based (no install required), lobby/waiting room, screen sharing, optional shared note-taking via Etherpad. Organizations with technical capacity can self-host a Jitsi instance for full control over infrastructure and branding.

Privacy: This is where Jitsi requires honest nuance. End-to-end encryption is available but must be manually enabled, and it only works when all participants are using a supported desktop browser or the native app — not all mobile browsers support it. On the public meet.jit.si server, 8x8 operates the infrastructure and has server-level access to unencrypted calls. Self-hosting removes that dependency entirely and is the configuration that delivers the privacy Jitsi is known for — but it requires technical staff to set up and maintain.

Best for: Tech-comfortable organizations willing to verify E2EE is actually active, or organizations with the capacity to self-host. An excellent choice if you can run your own instance. On the public server without E2EE enabled, the privacy advantage over Zoom is smaller than it might appear.

Proton Meet

Proton Meet launched on March 31, 2026, and it's worth paying attention to. Proton — the Swiss company behind ProtonMail and Proton VPN — has spent a decade building privacy-first alternatives to Google's tools. Meet is the last piece: a video conferencing platform with end-to-end encryption baked in at the architecture level, not bolted on as an option.

Free tier: Up to 50 participants, 1-hour call limit. Requires a free Proton account to host. Guests can join without any account.

No-account option: Up to 4 participants with no account required at all — just visit meet.proton.me.

Paid: Meet Professional at $7.99/user/month supports calls up to 24 hours and up to 100 participants (higher-tier Proton Workspace plans support up to 250). Proton Workspace Standard bundles Meet with encrypted email, calendar, drive, and VPN starting at $13/month.

Key features: Screen sharing, in-call encrypted chat, background blur, noise reduction, persistent named meeting rooms, and tight Proton Calendar integration. Meetings can also be added to Google or Microsoft calendars, so participants don't need to switch their whole setup.

Privacy: End-to-end encrypted by default for all calls, using the MLS (Messaging Layer Security) protocol — an open-source standard that has been independently audited. Not even Proton can access call content. Meeting passwords are embedded as URL hash fragments, meaning Proton's servers never see them. Proton is based in Switzerland and falls outside the jurisdiction of the US CLOUD Act — a meaningful structural protection for organizations concerned about government access to data.

The honest caveat: Proton Meet launched in March 2026 and is still early. Launch-day reviews were generally positive, but real-world experience — including ours — has surfaced bugs and inconsistent video quality. These are likely growing pains rather than structural limits, but it's worth testing before routing an important call through it. Feature parity with Zoom isn't the goal or the claim — privacy is. For now, treat it as the right tool for sensitive conversations where privacy outweighs polish, and keep Zoom or Google Meet as your fallback for large-group calls where reliability matters most.

Best for: Sensitive strategy conversations, coalition coordination, any meeting where content could attract legal scrutiny. The free tier is generous enough for most organizing use cases, and the no-account-required joining removes the biggest friction barrier for participants.

Signal

Signal isn't primarily a meeting platform — it's an encrypted messaging app that also does video calls. But for organizations that are already using Signal (which, if you've read our earlier articles on communication infrastructure, you should be), it's worth knowing what it can do.

Free: Entirely free, always. Signal is a nonprofit funded by donations and has no commercial interest in your data.

Paid: None.

Key features: Group video calls up to 75 participants (updated in February 2026), screen sharing, raise-hand, emoji reactions, call links for easy joining. Available on iOS, Android, and desktop (Windows, Mac, Linux).

Privacy: End-to-end encrypted by default, for every call, always — this is Signal's foundational promise and the one it has never compromised. Signal cannot access your call content. No ads, no data collection, no AI training. The Signal Protocol, which underpins the encryption, is the gold standard that other apps have adopted.

The real limitation: everyone in the call must have Signal installed and an account linked to a phone number. There's no browser-based joining and no guest access. This makes Signal excellent for established organizing teams where everyone's already connected, and less practical for calls with external participants, coalition partners, or new volunteers who haven't set it up yet.

Best for: High-trust, established teams already on Signal — leadership calls, security-sensitive planning, coordination with people you'd trust with sensitive information. For those conversations, it's the strongest option available.

At a glance

Choosing the right tool for the conversation

The honest answer is that you probably don't need to pick one platform and use it for everything. A tiered approach — matching the tool to the sensitivity of the conversation — is more practical and more realistic than asking every volunteer to adopt new software overnight.

For low-stakes, large-group calls — chapter updates, public webinars, new volunteer orientation — Zoom or Google Meet are fine. Content isn't sensitive, participation rates matter, and the friction of asking everyone to use an unfamiliar platform isn't worth it.

For internal organizing strategy, coalition coordination, and anything involving sensitive decisions — switch to Proton Meet or Signal. Proton Meet has the lower barrier to entry: guests can join without an account, so you're not asking coalition partners or new participants to install anything. For groups already on Signal, Signal calls are the stronger choice.

For your highest-sensitivity conversations — legal strategy, subpoena risk, security planning, discussions of specific individuals — Signal, with confirmation that E2EE is active, or Proton Meet with meeting lock enabled to prevent uninvited participants.

The transition doesn't have to be all-at-once. Start by routing your most sensitive conversations to a more secure platform. Keep routine coordination where it is. As your team gets comfortable, expand from there.

One clarification on scheduling tools

A note worth making: Calendly is not a video conferencing platform. It's a scheduling tool — it collects availability, lets external contacts book time on your calendar, and generates a Zoom, Meet, or Teams link for the actual call. It's genuinely useful for one-on-one meeting booking, but it doesn't host meetings. Group calendars and scheduling infrastructure — including the privacy implications of calendar data — are a full topic in their own right, and we'll cover them in an upcoming article.

The bottom line

The platform you meet on is part of your organizing infrastructure. For most conversations, the convenience of Zoom or Google Meet is a reasonable trade. For conversations that matter — where you're planning, strategizing, or discussing anything that could invite scrutiny — the platform deserves the same deliberate choice you'd make about your email list or your contact database.

Proton Meet's launch in early 2026 closes a real gap. For the first time, there's a polished, genuinely end-to-end encrypted video platform with a free tier generous enough for most organizing use cases and no barrier to joining for participants without an account. Combined with Signal for your highest-trust conversations, the toolkit is now complete.

The question isn't whether secure options exist. They do. The question is whether you're using them for the conversations that warrant it.
