Read this page as one judge. Each weighs the same scores by what they care about.

The Skeptic

Weighted verdict

Has read many pages claiming end-to-end encryption and wants the sentence that says which meetings, on which plan, with what turned off. Also reads for the participant cap, the dial-in minutes, and where recording storage stops being free.

Same scores as the panel view — this lens weights them the way this judge cares.

Scored by The Skeptic

The meeting itself

How this is scored

Whether the call works: participant capacity, video and audio quality under load, screen sharing, breakout rooms, moderation, and what happens on a bad connection.

0 — Small meetings only, no screen sharing worth the name, no moderation controls, and the call degrades without telling anyone.

3 — Standard meetings with screen sharing and mute-all, but low participant limits, no breakout rooms and no bandwidth adaptation stated.

5 — Meetings at the scale most teams need with screen sharing, breakout rooms, host moderation, and documented behaviour on constrained connections.

8 — Large meetings and webinars with published capacity limits, per-participant moderation and waiting rooms, layout control, simulcast or adaptive bitrate stated, and reliable behaviour on mobile networks.

10 — Scale and control are engineering claims the vendor stands behind: capacity published per plan and per region, selective forwarding with adaptive quality documented, live streaming, hardware-room support, and diagnostics an admin can read after a bad call.

Report an error

The Skeptic

Breakout rooms are documented down to the working limits — up to 8 rooms, random or self-select assignment, duration that closes rooms automatically, invited late joiners — and moderation is real: per-user promote, remove and mute, affirmative participant permissions, presenting policy, and a lobby where arrivals wait for moderator review. What I could not find is a published participant capacity for the software itself, any statement of adaptive bitrate or simulcast, or what happens to a call on a constrained connection; the low/medium/high video setting is a user choice, not an adaptation. 4 5 2

Encryption & meeting access

How this is scored

What is actually encrypted and against whom, plus who can get into a meeting. Judged on documented mechanism rather than on the word "encrypted".

0 — Transport encryption only, undocumented; meetings joinable by anyone with a link and no lobby.

3 — TLS in transit and encryption at rest, with the vendor holding all keys; access control is a passcode.

5 — The above plus a lobby or waiting room, host-controlled admission, per-meeting passcodes, and a clear statement that the vendor can technically access media.

8 — Optional end-to-end encryption for meetings with the trade-offs named (which features stop working), documented key handling, SSO-gated joining, and per-meeting access policies.

10 — End-to-end encryption available without surrendering the product — its cryptography documented or open source, key management explained, identity verification for participants, and the vendor stating plainly what it can and cannot see.

Report an error

The Skeptic

The pages document who gets in — guest policies of "Always ask moderator", "Always accept", "Always deny", moderator lobby review, and SAML sign-in for Personal Rooms, in beta, tested against Shibboleth, ClassLink and Azure AD — but I found no public information on what is encrypted, in transit or at rest, or who holds keys. The only security language on the captured pages is the privacy policy's "reasonable administrative, technical and physical measures", which is a promise, not a mechanism, and there is no end-to-end encryption statement with its feature trade-offs. 5 6 3

Reach & accessibility

How this is scored

Whether everyone who needs to join can: browser without an install, dial-in, low bandwidth, guests without accounts, captions and keyboard operation.

0 — A desktop client is the only way in; guests must create an account.

3 — Browser joining exists but is degraded, guests can join by link, and there is no dial-in and no accessibility statement.

5 — Full-feature browser joining without an install, guest access by link, mobile apps, and a stated accessibility posture.

8 — Telephone dial-in with numbers listed, live captions, keyboard-navigable and screen-reader-tested interface, and documented low-bandwidth behaviour.

10 — Reach is designed for: browser parity with the client, dial-in across the regions the customer operates in, live captions and translation, a published accessibility conformance report, and a usable experience on a poor mobile connection.

Report an error

The Skeptic

Accessibility is the best-evidenced thing in the evidence: a WCAG 2.0 Level AA statement validated in September 2023 by an external CPWA expert, Section 508 and EN 301 549 coverage, JAWS screen-reader support, keyboard shortcuts, dark mode, and moderator-enabled live captions with per-speaker setup and a viewer CC toggle — with exceptions honestly named (Shared Notes, tutorial material, presenter view). We found no public information on telephone dial-in or mobile apps, and the low-resolution video option is the only gesture toward a poor connection. 8 7 2

Recordings, retention & admin control

How this is scored

A recording is personal data about everyone in the room. Who may record, who is told, where it is stored, how long it lives, and what the works council can switch off.

0 — Anyone can record, storage location unstated, no retention rule, no admin policy.

3 — Host-only recording with a notification, but storage region unstated, retention manual, and no organisation-wide policy control.

5 — Admin policy over who may record, participant notification and consent prompt, stated storage region, and manual deletion that works.

8 — Automatic retention and deletion per policy, recordings encrypted at rest with access logged, transcription handled with its own retention rule, and attendance or analytics features that can be switched off for co-determination.

10 — Built for a works agreement: every recording, transcript and analytics feature independently switchable and documented, retention executed and evidenced, an audit trail of who accessed which recording, and no participant-level behavioural scoring at all.

Report an error

The Skeptic

Recording cannot start by accident — enabling it at meeting creation "does not auto-capture" and a moderator must press the button, with stop and pause — and recordings default to Unlisted with access only via direct URL, while administrators can search, filter, rename and delete across the server. But we found no public information on storage region, retention beyond the free tier's "recordings expire after 7 days", encryption of stored recordings, an access log, or a consent prompt for participants; and the Learning Analytics Dashboard assigns each student a relative activity score, which is participant-level behavioural scoring by design. 9 10 11

Integrations & deployment

How this is scored

Calendar, identity and the wider stack — plus, in this category, whether the product can be run on the customer's own infrastructure at all.

0 — No calendar integration, no SSO, no API; cloud-only with no alternative.

3 — One calendar integration and basic SSO, no API worth building on, cloud-only.

5 — Calendar integration for the major suites, SAML or OIDC SSO, a documented API for scheduling, and room-system support.

8 — The above plus SCIM provisioning, embedding via SDK, webhooks for meeting events, and either a self-hosted option or a documented private-cloud deployment.

10 — Deployment is the customer's choice: a genuine on-premises or private-cloud option with the same features, open protocols or open source, embeddable SDKs, and identity integration that does not require the vendor's directory.

Report an error

The Skeptic

Deployment is the customer's choice in the fullest sense: "Any school can easily set up their own BigBlueButton server", the software is open source, and Moodle 4.0 ships with BigBlueButton built in — over 20,000 registered Moodle sites — alongside Canvas, Sakai, D2L, Jenzabar and Schoology, with room behaviour, scheduling and recording manageable inside the LMS. SAML sign-in exists in beta; we found no public information on calendar integration for the major office suites, a documented scheduling API, SCIM provisioning, webhooks or an embeddable SDK. 1 11 12 6

European sovereignty

How this is scored

Where media and metadata are processed, who the contracting entity is, which subprocessors carry the traffic. Independently sourced by the sovereignty pipeline; scored here as this buyer weighs it — which in this category is heavily.

0 — Non-EU vendor and contracting entity, media routed through unstated regions, subprocessors unnamed.

3 — EU data residency for storage while media relays or metadata remain non-EU, or the contracting entity sits outside the EU.

5 — EU hosting and an EU contracting entity, but parts of the chain — relays, analytics, support tooling, transcription — are non-EU without an explained safeguard.

8 — Media and metadata processed in the EU on named infrastructure, EU contracting entity, complete subprocessor list published, any non-EU processing named with its legal basis.

10 — Sovereign end to end and evidenced: media never leaves the EU, every subprocessor European, certification published, and an on-premises option that removes the question entirely.

Report an error

The Skeptic

The contracting entity is BigBlueButton Inc. at Carleton University, Ottawa, Ontario — outside the EU — and we found no public information on where media or metadata are processed or which subprocessors carry the traffic, beyond a privacy policy naming Google Analytics on the Sites and noting servers "may be hosted by a third party service provider". Self-hosting lets a customer answer the residency question for themselves, but the vendor's own captured pages evidence no EU processing, no named infrastructure and no certification. 3 2 1

Pricing transparency not rated — the vendor publishes no price

How this is scored

Whether a buyer can compute the annual invoice for their host count — including the capacity, dial-in and recording storage they actually need — from public pages alone.

0 — No public prices at all; every tier is a sales conversation.

3 — A per-host headline exists, but participant caps, dial-in minutes or recording storage are unpriced or unmentioned.

5 — Per-host prices public with billing period stated and capacity limits given, but at least one commonly needed piece (webinar capacity, dial-in, storage) sits in an unpriced add-on.

8 — Every tier and add-on priced publicly with per-host maths, capacity limits, dial-in rates, storage allowances, minimum term and VAT treatment stated.

10 — Complete price computability: a calculator producing the annual invoice for a given host count, meeting size and recording volume, including overage and per-region dial-in.

Report an error

The Skeptic

The only priced offering on these pages is free, and its limits are stated to the digit: Blindside Networks' free Moodle 4.0 hosting with "class sizes up to 25 users, viewers see only moderator's webcam, maximum of 60 minutes per session, and recordings expire after 7 days". Every paid path is "reach out to any of the companies that provide hosting" — a sales conversation — so a buyer cannot compute an annual invoice from public pages; we found no per-host price, no dial-in rate and no storage allowance stated anywhere. 11 1
