Microsoft 365 E3 vs E5

Microsoft 365 is widely recognised as the go-to business IT solution provider supporting millions of businesses around the world to be more productive and collaborative around-the-clock. Known for its Office suite of apps, Microsoft 365 has been powering everyday business activities for years.  As businesses adopt more of the features included in their Microsoft 365 licensing plan and experience the benefits in terms of productivity, collaboration, and cyber resilience, they often seek additional ways to benefit from advanced functionality, and naturally look to move to the next plan type.

As businesses become increasingly security-conscious in response to emerging threats and look to find ways to protect their data, they often consider whether the existing licensing plan is sufficient to meet their needs. 

In this post, we explore the benefits of upgrading from Microsoft 365 E3 to E5 plan, and why businesses should consider investing in additional features. 

Whilst the E3 plan offers excellent protection from cyber security, businesses can benefit from even greater advanced security, compliance capabilities and sophisticated business analytics by upgrading to the E5 plan. 

Here are some of the most common benefits that organisations choose to take advantage of when upgrading to Microsoft 365’s E5 plan.

Enhanced security capabilities 

The primary reason businesses move from E3 to E5 is for the extensive and advanced security features that come with upgrading, which offer additional levels of security and resilience. The advanced features covered include protection against targeted cyberattacks with Microsoft Defender for Identity, protection against malicious threats with Microsoft Defender for Office 365 and Microsoft Defender for Endpoint, which both reduces the risk of attacks from happening but also detects when they have, allowing you to take swift action. With an E5 plan, 97% of threats are automatically eliminated or contained.

Advanced analytics and insights 

With an E5 plan, users can access advanced Power BI capabilities with Power BI Pro, including the ability to share and collaborate on reports, as well as taking advantage of generative AI-enabled insights to support with business decision making. With Power BI Pro, access to real-time insights has never been easier. 

Bolstered compliance

By upgrading to E5, businesses may be able to replace disparate 3rd party vendor solutions, keeping everything you could possibly need under one roof, which in itself offers data protection benefits as the number of locations you’re sharing sensitive data is reduced.

Internal risk management

At a time when 93% of businesses are concerned about insider risk, Microsoft 365 E5 plan provides businesses with rich insights about risky users and opportunities to automate risk management processed to restrict those users to protect against data breaches. With E5 licensing, businesses can protect and govern sensitive data better than ever before.

Improved identity and access management

Through Azure Active Entra ID (Formerly Azure Active Directory), businesses can protect access to data and resources through an enhanced and easy-to-update access policies. Manage access and identified in one central place, keeping users productive with a unified experience that spans multi-cloud environments. 

Is the E5 upgrade right for your business?

When you compare Microsoft 365 E3 and E5 licenses side-by-side, it’s no surprise that E5 comes out on top. With the investments Microsoft are making in the security of their customers, businesses can rest assured knowing that their systems have the best possible security.

Despite a higher per-license cost, the benefits of upgrading make the investment both a sensible and strategic one. An independent study by Forrest Consulting found an average return on investment of  203%, with many businesses reporting that prior to moving from E3 to E5, they had duplicate capabilities and solutions that they have since been able to consolidate. 

If you are concerned about an unforeseen cost, you can look at your business use case and consider which users would benefit from an upgrade, without having to upgrade your entire workforce.

How can businesses dispose of devices in an environmentally friendly way?

What is WEEE compliance? Electronic waste (e-waste) is one of the fastest growing waste streams today, with the UK generating 1.7 million tonnes* per year. As our reliance on electronic devices such as laptops, desktops, mobiles, and office equipment increases, so does the importance of responsible IT equipment disposal in the UK. When devices become faulty or outdated, the vast majority are simply disposed of, adding to the mounting electronic waste (e-waste) in landfills. This creates even more WEEE (Waste Electrical and Electronic Equipment). Effective responsible IT asset disposal in the UK is crucial to reduce environmental impact and support a sustainable future. With rapid technological advancements, upgrading IT infrastructure, and increasing regulations on WEEE compliance, adopting eco-friendly electronics recycling solutions is more important than ever. If we don’t all start to reduce, reuse, and recycle electronic devices, this is only set to get worse. We all have a role in minimising e-waste in the workplace, supporting the planet, and reducing demand for resource-intensive manufacturing What do companies do with old electronic devices? According to Sue Owens, Head of Supply Chain Services at Wavenet: “There isn’t a single answer to the climate crisis, or how we can recycle our way out of trouble, but responsible electronic device recycling and secure data destruction are essential parts of the solution. We need to look at all methods of recycling. Even the smallest contribution in reducing e-waste in the workplace adds up to be part of the bigger picture.” Recycling old laptops, mobiles, and other IT hardware not only helps manage the rising tide of end-of-life equipment recycling but also ensures compliance with WEEE directives. Proper certified electronic waste disposal providers help companies turn obsolete devices into environmentally safe recyclables or components, reducing the need for raw material extraction. Sue continues: ”The more organisations recycle, the less we need to mine. While the mining industry is a major contributor to planet-warming emissions, it also holds the key to a net-zero future. We don’t need to extract more – we need less. As clean energy and EVs expand, the total amount of materials mined will actually decrease, and we can significantly reduce reliance on coal that still fuels the industry’s revenues. Less mining, more sustainability – that’s the future we must build. To make a difference, it’s up to organisations to recycle whatever we can; however, data destruction is critical to the security of your business. Compliance with the WEEE directive and recycling units back into the market, either as components, or broken down into their elements is a huge contributor.” How do businesses recycle computers and phones?

A happy house tenant is using an app on her phone to report a home issue to her housing provider
From risk to resolution: how Active Assessor helps you stay ahead of Awaab's Law

What does Awaab's Law mean and why does it matter? Damp and mould aren’t just inconvenient maintenance problems - they’re serious risks to tenant health, regulatory compliance, and the reputation of housing providers. Nearly 1 in 7 social homes in England failed to meet the Decent Homes Standard in 2023¹. On top of that, the NHS is estimated to spend £1.4 billion a year treating health issues related to cold, damp housing². And yet, more than half of tenants experiencing condensation, damp or mould don’t report it. Often, they don’t recognise the early signs, or they simply don’t believe they’ll be taken seriously. This silence leaves landlords in the dark and turns small, fixable issues into expensive, high-risk problems. From October, social landlords will be legally required to fix emergency hazards within 24 hours and investigate and repair dangerous damp and mould within set timeframes, under new legislation known as Awaab’s Law. Introduced in memory of two-year-old Awaab Ishak, who tragically died in 2020 after prolonged exposure to mould in his social housing, the law represents a major step toward improving housing safety and quality. It allows tenants to take legal action if landlords fail to comply and will be rolled out in phases, beginning with damp and mould, to ensure effective implementation. This approach aims to deliver meaningful, lasting change while honouring the efforts of Awaab’s family to secure justice. Awaab’s Law also supports the government’s broader plan for change, which includes a commitment to building 1.5 million new homes and delivering the biggest improvement to social and affordable housing in a generation. The challenge: strained teams & outdated systems Most housing providers care deeply about tenant safety. The problem isn’t willingness—it’s capacity. Maintenance teams, IT departments, and customer contact centres are already stretched thin. Spotting early-stage issues requires tools they simply don’t have. Traditional, manual inspections are expensive and slow. Reactive workflows leave little room to get ahead of problems. And despite growing demand for proactive service, only 13% of customers actually receive it. The systems many teams rely on today are fragmented, outdated, and not fit for the pressures of a post-Awaab world. The solution: Active Assessor by 8x8
