Microsoft 365 E5 Security add-on: What you Need to Know

Hopefully, we all know how important safeguarding our organisation’s data is by now. In an era where cyber threats are escalating in both frequency and sophistication, and where we’re more digitally interconnected than ever, it’s crucial for organisations to implement robust, proactive, and user-friendly security measures to ensure that data and people are protected.  

Recognising this pressing need, Microsoft has introduced the Microsoft 365 E5 Security add-on for Business Premium subscribers, offering organisations access to advanced security features that may have been previously reserved for larger enterprises with more spending power – great news!

Of course, security is crucial in Microsoft 365 (M365) for several reasons; it’s a widely used platform (given that it has been adopted by over 2 million companies worldwide), making it a prime target for cyber criminals, and most organisations store a significant amount of sensitive information inside M365, including emails, documents, and customer data.

More than this, though, many industries have transitioned to remote or more flexible working conditions in recent times, making it essential to secure remote access to M365, while also complying with strict data protection regulations (GDPR, HIPAA, or PCI-DSS, e.g.) to ensure the security and privacy of sensitive information.

Yes, there can be no doubt about it, customers of M365 have a lot on their plate when it comes to their security obligations.

The Shared Responsibility Model

To add to the above, it’s also worth mentioning Microsoft’s Shared Responsibility Model – a matrix designed to lay out the security responsibilities of both Microsoft and M365 customers.

You see, under the M365 Security and Recovery Model, Microsoft operate the cloud infrastructure, ensuring physical security, network protection, and the overall availability of the services. However, as part of the cloud service agreement, customers are responsible for securing and managing their data within these environments, including data protection measures like data backups and the application of best practice configurations.

In essence, Microsoft’s shared responsibility model shifts the onus of data protection and security management to the users of its services, with clear lines drawn about what Microsoft’s responsibility is and what the customer’s responsibility is.

Microsoft 365 Business Premium and the security imperative 

M365 Business Premium is a comprehensive subscription plan primarily designed for small and medium-sized businesses. It combines productivity tools such as Office apps, email/calendar, OneDrive, and Teams with security features, e.g., Microsoft Defender for Office 365 and Microsoft Entra ID.

Many organisations choose M365 Business Premium to enable productivity, enhance scalability, and basically to empower their workforces with the tools they need to operate efficiently and securely inside modern workplaces.

Still, ongoing digital transformation efforts we’ve witnessed in recent years underscore the imperative for enhanced cyber security for almost all Microsoft 365 users – something business leaders must prioritise. After all, the economic impact of cloud cyber security breaches can be devastating, resulting in any (or combinations of) the following:

• Regulatory fines and legal costs:Non-compliance with data protection laws such as GDPR or HIPAA can result in hefty penalties.
• Reputational damage:Data breaches erode customer trust, potentially leading to reduced revenue and client attrition.
• Operational downtime: System outages may cause delays, impacting customer service and productivity.
• Recovery costs: The expenses associated with recovering from a cyber incident, including restoring data and systems, can be substantial.
• Insurance premiums: Following a breach, companies often face higher cyber insurance premiums.

There really is only one way to mitigate the potential impacts of cloud cyber security breaches upon people and businesses, and that’s by investing in robust cyber security measures and backup solutions.
