Running a small or mid-sized business these days isn’t easy; you’re juggling growth, customers, operations, and somewhere in the middle of it all, security keeps knocking louder than ever. Cyber threats are getting sharper, compliance demands are piling up, and even cyber-insurance providers are starting to grill you with tough questions.
Now, if you’re already on Microsoft 365 Business Premium, you’ve got a solid security foundation in place. It covers the essentials: helps keep your data safe, fends off common threats, and manages how users access your systems. That’s a great start.
But the real question: is “good enough” really enough when it comes to keeping your business safe?
And that’s where the new option comes in: Microsoft 365 E5 Security, now available as an add-on to Business Premium.
In simple terms, it means SMBs can finally access enterprise-grade security without the enterprise-grade price tag.
So, why should your SMB be seriously looking at E5 Security today? Let me break it down for you, focusing on what this actually does for your business in real-world scenarios.
Business Premium vs E5 Security: What You Get
Before deciding whether you need the E5 Security add-on, it helps to see exactly what you already have with Business Premium and what extra protection E5 brings. The table below breaks it all down, so you can clearly see which features come standard and which ones give you that next-level protection for your business. This way, you’ll know exactly where the gaps are—and how E5 Security fills them.

Why SMBs Should Consider E5 Security Add-on
When it comes to security, SMBs often think, “We’re too small to be targeted.” The truth is, small and medium businesses are increasingly in hackers’ crosshairs because attackers know that smaller teams often have fewer defenses in place. That’s why adding E5 Security can make a huge difference. It doesn’t just layer more tools on top, it strengthens the areas where SMBs are most vulnerable and gives you proactive defenses.
1. Stop Identity Attacks Cold with Enhanced Identity Protection:
Identities are a primary target for attackers. Hackers love going after user credentials. Business Premium gives you MFA and conditional access, but E5 Security takes it further with real-time identity attack detection, automated governance, and advanced workflows.
- Entra ID Protection, powered by P2, sees these anomalies in real time, flags them as risky, and can even automatically block access or demand stricter verification.
- Plus, ID Governance helps automate frustrating manual IT tasks like employee onboarding, ensuring access is granted correctly and efficiently from day one, saving you headaches and potential security gaps.
Your team stays productive, IT spends less time fixing access issues, and threats get blocked before they cause damage.
2. Advanced Hunting for Hidden Threats & IoT Security for Everything Else:
While Defender for Business in Premium is excellent, Microsoft Defender for Endpoint Plan 2 provides deeper forensic capabilities. If you ever have a serious incident, having 6 months of data retention on devices means you can truly investigate what happened, trace the attack’s origins, and ensure every trace is removed.
And Advanced Hunting allows your security team (or a Managed Detection and Response (MDR) provider) to proactively search for threats that might be undetected. Critically, it also extends robust security to your IoT devices. In a world where smart devices are everywhere – from smart TVs to building management systems – these are often overlooked entry points for attackers. E5 Security ensures they’re not your weakest link.
3. Email and collaboration protection is next-level:
We’ve all been there, clicked a link in an email without thinking twice. It happens. Business Premium already helps by scanning URLs in real time, checking attachments for malware, and blocking obvious phishing attempts. That’s great for stopping most threats before they reach your inbox. But E5 Security takes it to the next level. It doesn’t just wait for an attack to happen—it actively trains your team with simulated phishing attacks, so employees learn to recognize suspicious emails in a safe, controlled environment. On top of that, it automates the response if something does slip through, investigating potential breaches and taking action without IT having to lift a finger. Plus, you get detailed reporting on who clicked what, which emails were targeted, and the overall risk posture of your organization. The best part? You’re not just reacting to threats—you’re preventing them and preparing your team to stay one step ahead.
4. Stop Shadow IT and Secure Your Cloud Apps:
This is huge! Most SMBs use dozens, if not hundreds, of SaaS apps. Do you know every cloud app your employees are using? Do you know if they’re secure? Probably not. This is “shadow IT,” and it’s a massive security blind spot. Microsoft Defender for Cloud Apps helps you discover all the cloud apps in use, assesses their risk, and ensures only approved applications are used. It actively protects against SaaS-based attacks and the increasingly common OAuth attacks (where malicious apps gain too much access).
5. Cost-effective advanced protection:
Security tools aren’t cheap! If you tried to buy all the protections E5 Security offers separately, advanced identity protection, endpoint security, email safeguards, XDR, and SaaS monitoring—you’d end up spending a small fortune. The beauty of the E5 Security add-on is that it bundles all of these enterprise-grade features together in one package, and at a price that’s way more manageable for SMBs.
In fact, you’re looking at roughly 57% savings compared to purchasing each product individually. That means you get high-level, sophisticated security without the enterprise-level budget. It’s a practical way to protect your business, keep your team productive, and stay ahead of threats, all while being smart about costs.
The Smart Investment for Your Business’s Future
Look, the reality is that the cost of a data breach – in terms of financial loss, reputational damage, and regulatory fines – far outweighs the investment in proactive security. What’s truly impressive is that purchasing E5 Security as an add-on offers an incredible 57% savings compared to buying all these powerful individual products separately. This isn’t just about spending more; it’s about making a highly strategic, cost-effective investment in your business’s resilience.
Don’t wait for an incident to realize you needed more. Consider elevating your security posture with Microsoft 365 E5 Security today. It’s about protecting your data, your employees, and ultimately, your business’s future.
