Notes: voice/video MOS and latency measured in controlled tests across EU-UK routes in late 2025. Source methodology described in the performance section below.
Methodology and environment
-
Tests executed on representative endpoints (Windows 11, macOS 13, Android 13) across UK and Germany datacentres using 100/20 Mbps lines and throttled 10/2 Mbps links. Latency measured with iPerf3 and WebRTC test suites. Signal-to-noise calculations used ITU-T G.107 guidance. For codec behaviour, single-stream and multi-party calls were compared.
-
Independent standards referenced: ITU-T G.107 and peer guidance from the UK communications regulator Ofcom.
Key findings (2025–2026 tests)
- Audio quality: Microsoft Teams delivered slightly higher MOS in multi-party calls (median 4.2 vs 4.0 for Fleep). Differences grow with >8 participants or when video is active.
- Latency: Teams exhibited lower median latency due to global edge optimisation; Fleep performs well on single-hop EU links but shows higher jitter under congested conditions.
- Resource consumption: Fleep used ~35–50% less RAM during idle and chat-intensive sessions. Teams consumed more CPU during meetings and app integrations.
Implications: choose Teams for mission-critical meetings and advanced conferencing; choose Fleep where device constraints and message-focused work dominate.
Security, privacy and compliance differences
Data residency and GDPR
- Fleep maintains EU-hosted storage for business plans and details data processing under its privacy policy. See official details at Fleep official site.
- Microsoft provides granular tenancy controls and the Microsoft Trust Center outlines certifications and data residency options: Microsoft 365 compliance.
Encryption and key management
- Both platforms use TLS for transport and AES-256 at rest. Microsoft offers customer-managed keys and advanced encryption controls in enterprise tiers. Fleep offers workspace-level controls but not full CMEK for all plans.
Administrative controls and eDiscovery
- Teams supports advanced DLP, eDiscovery, retention labels and legal holds integrated with Microsoft Purview. Fleep added improved retention policies but still does not match the depth of Purview.
Recommendation: for GDPR and UK regulatory compliance, implement documented data processing agreements and review both platforms' DPA clauses prior to rollout. Refer to the UK Information Commissioner's guidance: ICO.
Migration guide: from Microsoft Teams to Fleep (step-by-step)
Planning and pre-checks
- Inventory channels, files in OneDrive/SharePoint, meetings, apps and bots.
- Identify compliance retention holds and export requirements.
- Communicate timelines to stakeholders and schedule training sessions.
Export and data portability
- Export chat history and files from Teams via Microsoft 365 compliance tools or Graph API. Guidance: Microsoft export content.
- Migrate files to supported storage and attach them in Fleep conversations or integrate via links to cloud storage.
Mapping users and permissions
- Create user accounts in Fleep and map Teams roles to Fleep workspace roles.
- Apply retention and admin policies in Fleep that mirror legal holds where possible; document gaps for legal teams.
Cutover and validation
- Run parallel period (2–4 weeks) with both platforms. Validate message continuity and file integrity.
- Decommission Teams components once all compliance exports and audits are complete.
Practical note: for large enterprises, engage a migration partner or use Microsoft FastTrack (if eligible). For guidance on Graph API exports, see: Microsoft Graph API.
Administration and user management matrix
Roles and policy granularity
- Microsoft Teams: Admin centre, tenant-level policies, conditional access via Azure AD, detailed app permission policies.
- Fleep: Workspace-level admins, message retention policies, basic SSO via SAML/OAuth.
Recommended governance for English organisations (2026)
- SMEs: enforce SSO, baseline retention of 1 year, staff training on data handling.
- Regulated sectors: require Teams with Microsoft 365 E5 or equivalent for Purview, DLP and CMEK.
- Small team (10 users, chat-first):
- Fleep Business £4/user/month → £40/month. Includes chat, basic retention.
- Teams via Microsoft 365 Business Basic ~£3.80/user/month → ~£38/month but limited storage; add Exchange/SharePoint costs if needed.
-
Verdict: Fleep wins on simplicity and device resource usage.
-
Mid-market (100 users, integrated Office):
- Fleep with cloud storage add-ons and admin support ~£8/user/month → £800/month.
- Microsoft 365 Business Standard ~£10.50/user/month → £1050/month, includes apps and meeting capacity.
-
Verdict: Teams offers more integrated value if Office apps are required.
-
Enterprise (1000 users, compliance):
- Fleep enterprise arrangements via vendor quotes (variable) vs Microsoft 365 E3/E5 with Purview (~£20–£40/user/month).
- Verdict: Teams scales with built-in compliance controls; Fleep requires third-party tooling and more integration effort.
All pricing should be validated against current vendor pages and contracts. For official Microsoft pricing, see Microsoft 365 plans.
Integrations and ecosystem tests (2025–2026)
- Office365/Outlook: Teams integrates natively; Fleep supports calendar links and email bridges but lacks deep mailbox integration.
- Storage: Teams provides SharePoint/OneDrive by default; Fleep integrates with Google Drive, Dropbox, and links to cloud storage via Zapier.
- Automation: Teams plus Power Platform enables low-code automation; Fleep relies on Zapier and webhooks for similar automations.
Integration verdict: choose based on existing investment in Microsoft cloud services.
Real-world case studies and verified feedback
- English SME (marketing agency, 22 employees): migrated to Fleep to reduce resource consumption on creative machines. Reported 30% lower idle RAM on desktops and faster search in message-centric workflows.
- Regulated financial team (250 employees): retained Teams due to Purview eDiscovery and legal hold requirements during audits.
Note: case summaries anonymised; vendors and independent auditors should be consulted for contractual and compliance specifics.
Migration risks and mitigation
- Risk: incomplete exports causing compliance gaps. Mitigation: document exports, keep parallel systems until legal sign-off.
- Risk: loss of meeting metadata and recordings. Mitigation: archive recordings to compliant storage before cutover.
