A lost laptop, a convincing fake invoice and an employee using a personal mobile for work can each become a costly business problem. For many small and medium businesses, Microsoft 365 Business Premium is the point where everyday email and document software becomes a practical security and device-management platform. This Microsoft 365 Business Premium review looks at whether the extra cost is justified for Australian businesses that need to protect data without building a large internal IT team.
The short answer is that Business Premium is usually a strong fit for businesses with 5 to 300 users that rely on Microsoft 365 and want better control over their devices, identities and information. It is not automatically the right licence for every worker. The value depends on how it is configured, managed and matched to the risks your business actually faces.
What Microsoft 365 Business Premium includes
Business Premium combines the familiar Microsoft 365 applications with security and management tools that are often missing from lower-tier plans. Staff receive the desktop, web and mobile versions of Word, Excel, Outlook, PowerPoint and Teams, along with Exchange email, OneDrive cloud storage and SharePoint for file collaboration.
The difference is what sits behind those productivity tools. Business Premium adds Microsoft Intune for device management, Microsoft Entra ID capabilities for identity control, and Microsoft Defender for Business for endpoint protection. It also includes Microsoft Defender for Office 365 Plan 1 features to help protect email and collaboration tools from phishing, malicious attachments and unsafe links.
For a growing Mackay business, this can replace a patchwork of separate services. Rather than paying for a basic email plan, a standalone antivirus product and an unmanaged collection of laptops, the business can apply consistent policies from one environment. That does not mean every security need disappears, but it creates a far better foundation.
Microsoft 365 Business Premium review: where it delivers value
The most useful feature is not usually an individual application. It is the ability to apply security rules consistently across the business.
Better control of business devices
With Intune, a business can enrol Windows computers, tablets and mobiles used for work. IT can apply security settings, require screen locks, deploy approved software, keep devices encrypted and remove business data if a device is lost or an employee leaves.
This is particularly valuable for businesses with field staff, remote workers, shared devices or staff using their own mobiles. A business does not need to inspect an employee’s personal photos or messages to protect its information. Proper mobile application management can separate work data from personal data and remove only the company content when necessary.
Intune also gives organisations a clearer picture of which devices are in use and whether they meet minimum requirements. That matters when a staff member connects to email from an old, unpatched laptop that nobody knew existed.
Stronger protection against common attacks
Most small business cyber incidents do not begin with a dramatic breach of a server room. They begin with a stolen password, a fake Microsoft sign-in page, a compromised mailbox or an attachment that should never have been opened.
Business Premium supports multi-factor authentication, conditional access policies and phishing protection. For example, a business can require an additional sign-in check when staff access Microsoft 365 from an unfamiliar device, or block access from devices that do not meet security standards. Email protections can flag impersonation attempts and inspect links before users open them.
Microsoft Defender for Business adds endpoint detection and response capabilities that go beyond traditional antivirus. It can identify suspicious activity, help isolate affected devices and provide useful investigation information. These tools are powerful, but they are not a set-and-forget substitute for monitoring, incident response procedures and staff awareness training.
A more practical way to support remote work
Remote work does not have to mean reduced oversight. Business Premium makes it easier to deploy applications, configure new devices and provide staff with access to the files and systems they need. OneDrive and SharePoint allow teams to collaborate on current documents rather than emailing multiple versions back and forth.
For offices with a mix of desktop computers, laptops and mobiles, central management reduces the time spent manually setting up each device. It also makes staff changes less disruptive. A new team member can receive a configured device and the right access from day one, while departing staff can be removed promptly from email, files and business applications.
The trade-offs to consider
Business Premium costs more per user than Microsoft 365 Business Standard, so it should not be treated as a blanket purchase without considering each role. A worker who only needs email and basic document access may not require the full Premium licence, while an office manager, director, accounts employee or field worker with sensitive customer information probably does.
Licensing also needs to be planned carefully. Microsoft licensing rules, included features and product names can change, and security capabilities are often affected by the way services are configured. A licence gives a business access to tools. It does not automatically create secure policies, enrol existing devices, clean up old user accounts or establish a tested response plan.
There is also a management overhead. Conditional access policies can accidentally lock out users if they are rushed or poorly tested. Device enrolment needs clear communication so staff understand what is managed on their work and personal devices. File-sharing permissions in SharePoint require a sensible structure, otherwise the business simply moves its messy shared drive into the cloud.
For very small businesses with a handful of devices and low-risk data, Business Standard combined with carefully selected security measures may be enough. At the other end of the scale, organisations with more than 300 users, complex compliance obligations or advanced security requirements may need enterprise Microsoft licensing and a more specialised security design.
What a successful deployment looks like
A good Business Premium rollout starts with the business, not the licence portal. First, identify the people, devices, data and systems that need protection. This includes company laptops, personal mobiles used for email, shared reception computers, Microsoft 365 mailboxes, cloud applications and any line-of-business software that depends on user sign-in.
Next, establish a baseline. Multi-factor authentication should be planned for all users, with secure recovery methods and administrator accounts treated separately. Devices should be enrolled and checked for encryption, operating system updates and endpoint protection. Email settings should be reviewed to reduce phishing and spoofing risk, while external sharing should be set at a level that supports genuine collaboration without exposing files unnecessarily.
The third step is operational discipline. New starters need a repeatable setup process. Departing staff need access removed quickly. Lost devices need a documented response. Security alerts need someone responsible for reviewing them. Backups also still matter. Microsoft 365 improves availability and provides retention features, but a separate backup strategy can be necessary when businesses need longer retention, simpler recovery or protection against accidental and malicious deletion.
This is where a managed IT provider can make a material difference. EHW Technology can help businesses assess their current Microsoft 365 environment, configure policies around real working practices and provide ongoing support when devices, users and threats change.
Who should choose Business Premium?
Business Premium is particularly well suited to professional services, construction and trade businesses, healthcare-adjacent organisations, finance teams, schools, not-for-profits and multi-site operators. In each case, staff often work from different locations, customer information is valuable and a failed laptop or compromised email account can interrupt operations quickly.
It is also a sensible choice for businesses replacing ageing computers. New Windows devices can be prepared with standard applications, security controls and user settings before they reach staff. That reduces setup time and helps ensure every device starts from the same secure baseline.
The strongest case for Business Premium is not that it provides more software. It is that it gives a business the controls to keep work moving when people are mobile, devices change hands and cyber threats target ordinary daily tasks. With sensible planning and active management, it can turn Microsoft 365 from an email service into a dependable part of the business security strategy.
