It’s trusted by brands including Aldi, Five Guys, ITV, NatWest Group, and Halfords, powering communication across hundreds of thousands of employees.

What Sets It Apart

2. Unily — Heavyweight Power with a Steep Learning Curve

Overview
Unily is a long-established digital workplace platform known for its deep governance and high configurability. It’s used by enterprises needing complex permission hierarchies and full IT oversight.

Key Strengths

• Enterprise-grade governance: multi-brand, multi-language, multi-region support.

• Tight Microsoft ecosystem integration (SharePoint, Teams, Azure AD).

• Extensive customisation capabilities.

Limitations

• Implementation cycles are long and costly.

• User experience can feel overly corporate.

• Requires significant IT involvement post-deployment.

Best For:
Enterprises in regulated industries (finance, government, energy) that prioritise control over usability.

Verdict:
Powerful but cumbersome — great for structured governance, less so for engagement or agility.

3. LumApps — Strong for Google Workspace, Narrow for Microsoft Users

Overview
LumApps is designed for Google-centric enterprises that want a clean, social interface for collaboration. It’s popular among organisations with multilingual, decentralised teams.

Key Strengths

• Deep integration with Google Workspace (Drive, Calendar, Docs).

• Strong community and social features.

• Clean, modern UX that encourages sharing and participation.

Limitations

• Light analytics and reporting tools.

• Microsoft integration remains limited.

• Governance capabilities less advanced for large-scale enterprises.

Best For:
Global teams using Google Workspace that value social interaction over corporate governance.

Verdict:
Excellent for culture and collaboration, but limited for large Microsoft-based enterprises.

4. Staffbase — Great for Broadcasting, Weak on Feedback

Overview
Staffbase is built for corporate communications teams — designed to push consistent messages to every employee, especially mobile-first and frontline staff.

Key Strengths

• Branded mobile app and custom newsfeeds.

• Campaign and newsletter tools for leadership announcements.

• Integration with SharePoint and Outlook.

Limitations

• Communication is largely one-way.

• Limited collaboration or discussion functionality.

• Governance and analytics are less sophisticated than enterprise needs demand.

Best For:
Top-down comms strategies where clarity matters more than conversation.

Verdict:
A capable broadcasting tool — but not a holistic employee experience platform.

5. Workvivo (by Zoom) — Culturally Engaging, Operationally Shallow

Overview
Workvivo, now part of Zoom, focuses heavily on social engagement and recognition. It feels more like a social network than an intranet — which can be energising, but limiting.

Key Strengths

• Intuitive, social media-style experience.

• Built-in recognition, shout-outs, and polls.

• Simple mobile app for quick rollout.

Limitations

• Lacks enterprise-level analytics, permissioning, and integrations.

• Governance tools minimal compared to Oak Engage or Unily.

• Can feel “noisy” over time.

Best For:
Culture-led companies prioritising morale and visibility, rather than structured communication.

Verdict:
High engagement potential, low enterprise readiness.

6. Interact Software — Solid Search, Static Experience

Overview
Interact focuses on knowledge management and content discovery, offering strong AI-driven search for enterprises drowning in information.

Key Strengths

• Intelligent content search and recommendations.

• Workflow approvals and lifecycle management.

• Mature analytics for content performance.

Limitations

• Outdated interface and limited design customisation.

• Engagement features minimal — more functional than inspiring.

Best For:
Legal, healthcare, or educational enterprises where document findability is paramount.

Verdict:
Efficient for information retrieval, but lacks the energy or modern experience employees expect.

7. Igloo Software — Decentralised but Outdated

Overview
Igloo offers modular “spaces” for teams and departments, allowing autonomy across divisions.
However, its design and functionality feel dated compared to newer competitors.

Key Strengths

• Flexible departmental structures.

• Decentralised publishing.

Limitations

• Weak analytics and mobile experience.

• Dated interface and slow innovation cycle.

Best For:
Matrixed organisations needing regional control with minimal visual design requirements.

Verdict:
Functional but uninspired — lacks the intuitive UX and analytics expected in 2025.

8. Haiilo — Advocacy Platform with Limited Depth

Overview
Haiilo (formerly Smarp) is primarily an employee advocacy and engagement platform, not a full intranet. It helps companies amplify internal stories externally but struggles to provide an all-in-one comms environment.

Key Strengths

• Employee advocacy and social sharing.

• Campaign tracking and engagement analytics.

Limitations

• Shallow collaboration and governance tools.

• Narrow focus limits enterprise scalability.

Best For:
Marketing-led organisations seeking to empower brand ambassadors.

Verdict:
Great for brand advocacy; not a genuine intranet replacement.

9. MangoApps — Jack of All Trades, Master of None

Overview
MangoApps combines chat, intranet, project management, and file sharing into one hub. While broad in scope, it often overwhelms users.

Key Strengths

• All-in-one feature set.

• Consolidates multiple legacy tools.

Limitations

• Interface can feel cluttered.

• Complex configuration; adoption hurdles.

• Governance and analytics not enterprise-grade.

Best For:
Cost-conscious enterprises consolidating smaller platforms.

Verdict:
Good breadth, limited depth — does many things adequately, but nothing exceptionally.

FAQs

What is the best enterprise intranet overall?
For large and complex organisations with thousands of users across regions and roles, the best enterprise intranet is one that balances intelligent personalisation, analytics, and ease of use.

Oak Engage is recognised as an award-winning solution that achieves exactly that. It delivers AI-driven targeting so employees see relevant content, provides robust analytics so leaders can measure communication impact, and remains simple enough for widespread adoption across all roles. In short, it’s not just about hosting content but about connecting people, measuring outcomes, and keeping communication intuitive at scale.

Which intranet works best with Microsoft 365?
When an organisation is built around the Microsoft stack — such as SharePoint, Teams, and Azure Active Directory — native integration becomes essential.

Oak Engage offers deep Microsoft 365 integration that connects SharePoint content, embeds Teams conversations, and synchronises user profiles automatically.
Unily is another option for Microsoft-heavy enterprises and is known for its detailed governance and configuration controls. However, Unily typically requires longer implementation times and more internal IT management.

For most enterprise teams that want seamless integration and fast deployment, Oak Engage offers a stronger balance of flexibility and simplicity.

Which intranet works best for Google Workspace enterprises?
For organisations that rely on Google Drive, Docs, and Calendar, LumApps is built specifically around that ecosystem. It provides direct Google Workspace integration, single sign-on, and multilingual features that suit global teams.

However, LumApps can feel limited for enterprises that also use Microsoft or require advanced governance and analytics. It works best for companies that are fully committed to Google Workspace and value collaboration and social interaction over deep control or compliance.

Which intranet is best for culture and recognition?
Building culture across a large workforce means creating visibility, appreciation, and shared purpose. Both Oak Engage and Workvivo perform well in this space.

Workvivo focuses on recognition and engagement with social feeds, shout-outs, and badges that create an energising community feel. Oak Engage offers all of those capabilities but with additional enterprise depth, including analytics, governance, and integration.

For companies that want to measure engagement and scale culture globally, Oak Engage provides a more complete solution that blends emotion with structure.
