Enterprise Intranet Comparison Table

Here are the top 9 enterprise intranet platforms including Oak Engage, 

1. Oak Engage - Best Enterprise Intranet Platform for Employee Engagement (2025)

Overview
Oak Engage is an award-winning enterprise intranet designed to support organisations with office-based, hybrid and frontline employees. Trusted by brands including Aldi, Five Guys, ITV, NatWest Group, and Halfords, Oak Engage helps to deliver consistent and secure communication across hundreds of thousands of employees. With a suite of innovative engagement tools, Oak helps improve employee retention and significantly boost intranet adoption rates. Halfords, for example consistently achieved an 84% adoption rate among their employees after launch.

Built for scale, Oak includes deep integrations with Microsoft 365 and SharePoint, enabling enterprises to structure and manage communication with the governance and reliability they need. Frontline employees benefit from personalised mobile access, while office and remote workers enjoy a seamless digital experience that reduces noise and centralises information. Oak’s combination of enterprise capability and everyday simplicity makes it a powerful solution for organisations seeking a modern intranet that truly reaches everyone.

Why Oak Engage Stands Out

Oak Engage combines enterprise-grade structure with mobile-first reach, giving companies the ability to communicate consistently across large, distributed workforces. Its blend of content governance, personalised delivery, AI-powered capabilities and seamless Microsoft 365 integration ensures that every employee receives the information they need — wherever and however they work.

Who Oak Engage Is Best Suited For

Oak Engage is ideal for organisations that:

• Have a large or distributed workforce across multiple sites

• Rely on Microsoft 365 or SharePoint and need deeper structure

• Need to reach deskless or frontline employees reliably

• Operate in regulated industries requiring governance and compliance

• Want a single, unified intranet that engages every employee

• Have hybrid teams needing both desktop and mobile parity

• Require multilingual or global communication support

Enterprise Use Case: NatWest Group

NatWest Group is one of the UK’s largest banking organisations, employing more than 80,000 people across office-based, hybrid and frontline roles. With such a diverse and highly regulated workforce, the organisation needed an intranet that would deliver clear, consistent and personalised communication at scale, ensuring every employee could access accurate information securely, wherever they worked.

Using Oak Engage, NatWest transformed the way it communicates with teams across the business. Oak’s unified news feed, personalised content delivery and deep Microsoft 365 integration allowed the organisation to replace fragmented channels with a single, reliable source of truth. Frontline and branch colleagues gained intuitive mobile access, while office and remote teams benefitted from structured communication, governance controls and improved visibility of important updates.

Why NatWest Chose Oak Engage

Impact & Outcomes

NatWest’s intranet has become a central part of the organisation’s digital workplace — improving clarity, reducing duplication and helping teams stay connected. The move to Oak Engage was recognised externally, with NatWest winning Best Intranet at the Institute of Internal Communications (IoIC) Awards. The platform now underpins communication and culture at scale, enabling leadership and internal comms teams to reach tens of thousands of employees with accurate, timely and relevant information.

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

• Simple mobile app for quick rollout.

Limitations

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

Key Strengths

• Workflow approvals and lifecycle management.

• Mature analytics for content performance.

Limitations

Overview

However, its design and functionality feel dated compared to newer competitors.

Key Strengths

• Flexible departmental structures.

• Decentralised publishing.

Limitations

• 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 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

1. 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.

2. How does an enterprise intranet improve employee engagement?

An enterprise intranet improves engagement by connecting employees to company news, culture, and one another. Features such as personalised content, recognition tools, and feedback channels help employees feel informed and valued, no matter where they work.

3. What are the benefits of using an enterprise intranet in large organisations?

For large or distributed enterprises, an intranet centralises communication, reduces email overload, and maintains consistent messaging across regions. It strengthens culture, speeds up knowledge sharing, and ensures that every employee has access to the same information.

4. How do I choose the right enterprise intranet platform?

Choosing the right intranet depends on your size, goals, and tech stack. Assess scalability, security certifications, ease of use, mobile experience, and integration with core systems like HR, CRM, and collaboration tools.

5. What makes an intranet suitable for frontline workers?

A frontline-friendly intranet offers mobile-first access, offline functionality, and role-based communication so employees without regular desktop access can still stay connected and informed.
