InviziPoll vs Slido
Slido helps facilitators capture questions, polls, and quizzes during meetings and conferences. InviziPoll is narrower: encrypted organizational polling where we can't read the responses and nothing links an answer to the person who gave it.
Just checking whether Slido is anonymous? Read the short answer
Choose InviziPoll for ciphertext-only workplace polls; choose Slido for in-meeting engagement, Q&A, and facilitator moderation workflows.
- InviziPoll for ciphertext-only workplace polls with structural anonymity.
- Slido for in-meeting engagement, Q&A, and facilitator moderation workflows.
- Slido runs inside the meeting; InviziPoll polls go out by email, Slack, single-use access codes or an open link and stay open for days.
Two products, two buyers
The overlap is real, but the default assumptions are different. Start here before scanning the feature table.

InviziPollBest for AnonymityAnonymous workplace polling that runs over days, with answers encrypted before they leave the respondent's browser.
Hybrid meeting engagement (Q&A, polls, surveys) with facilitator tooling.
Structural encryption-in-browser - anonymity follows architecture, not only UI toggles.
Markets truly anonymous participation even with SSO enabled - confirm backend visibility, exports, and retention against your policy.
Aggregate results, plus written answers word for word, shuffled and undated. Anyone who'd rather not be read can send just the topics they pick instead. No per-response timelines.
Exports and integrations oriented around meeting analytics and moderation.
Ciphertext-only storage plus native SIEM event webhooks on Business+; SCIM as a Pro add-on (bundled at Business).
SAML SSO (member and participant) and SCIM on Enterprise - compare cryptographic guarantees, not only identity feature checklists.
Respondents can assume operators cannot read individual answers; decryption happens only in authorized admin clients, not on our servers.
Slido publishes privacy commitments for Cisco-backed operations - validate how participant content is processed for your regions and retention policy.
SAML/OIDC SSO and native SIEM event webhooks on Business+; SCIM 2.0 as a Pro add-on (bundled at Business) - without exposing respondent plaintext through those channels.
SAML SSO (member and participant) and SCIM on Enterprise (Member SAML SSO required) - internal SIEM operations and third-party compliance integrations, not a documented native customer SIEM webhook.
Slack notifications for organizers; SAML/OIDC SSO and native SIEM event webhooks on Business+, SCIM 2.0 as a Pro add-on (bundled at Business) - without exposing respondent plaintext through those channels.
Deep meeting integrations (Webex ecosystem and common conferencing tools) - ideal when engagement happens inside vendor meeting chrome.
Slido capabilities vary by plan and configuration. Confirm specifics against their current documentation.
Is Slido anonymous?
Not in the ciphertext-only sense most HR reviewers require. Slido offers anonymous participation options for meetings, but validate backend visibility, exports, and retention against your policy. InviziPoll enforces anonymity by architecture: individual answers stay encrypted before upload.
Which one should you pick?
If both tools could technically run your poll, let the default assumption decide.
Choose InviziPoll when
- Risk reviewers reject tooling where identifiable submission timelines might exist for sensitive pulses.
- You need cryptographic separation between respondents and operators, not optional anonymous modes.
- The poll runs outside live meeting chrome but still needs native SIEM event webhooks and SSO on Business+.
Keep Slido when
- Audience interaction during hybrid or in-room meetings is the primary workflow.
- Facilitators need live quizzes, upvotes, and moderation inside meeting tooling.
- Deep Webex and conferencing integrations matter more than ciphertext-only storage.
How each vendor thinks about cost
Yes when cryptographic separation between operators and individual answers is the requirement - not when live meeting Q&A moderation is the primary workflow. Slido excels at in-meeting engagement; InviziPoll is purpose-built for encrypted workplace polling.
No. If live attendee moderation queues are core, keep Slido or pair tools intentionally. InviziPoll replaces the sensitive-polling layer - not always the facilitator UX.
Many teams do. Use Slido where meeting chrome and facilitator tooling matter, and InviziPoll where risk reviewers require documented ciphertext-only storage for employee ballots. Map integrations and data flows in procurement before combining tools.
Slido offers anonymous participation options, and hosts control whether anonymous questions are allowed. Confirm against their documentation whether backend visibility, exports, and SSO participant logs meet your policy. InviziPoll's boundary is architectural: individual answers stay encrypted end-to-end by design; see /blog/is-slido-anonymous and /security.
Both vendors offer enterprise identity paths - Slido documents SAML SSO (member and participant) and SCIM on Enterprise. InviziPoll offers SAML/OIDC SSO and native SIEM event webhooks on Business+, with SCIM as a Pro add-on (bundled at Business). Map each vendor against cryptography requirements, not only SSO availability, during vendor review.
