Microsoft 365 Business Premium: the security you already pay for but probably do not use

Most Israeli SMBs on Microsoft 365 Business Premium are paying for far more security than they use. Business Premium is not the cheapest Microsoft plan, and the reason it costs more is that it bundles a stack of protection that used to be sold separately to enterprises: endpoint detection, device management, conditional access, data loss prevention, and advanced email defence. The licence lands in the tenant, the features sit there ready, and in a lot of small offices almost none of them are ever switched on. You end up paying an enterprise price for a mailbox-and-Office experience. This is a walk through what is actually in the box, in plain terms, and the order that makes sense to turn it on.

First, Know Which Plan You Are On

Before anything else, confirm the plan. Business Basic and Business Standard give you email, the Office apps, and Teams, but not the security suite this article is about. Business Premium is the one that includes Microsoft Entra ID P1, Defender for Business, Defender for Office 365 Plan 1, Intune, and Purview data loss prevention. If you are not certain, the admin centre shows your licences under billing. It is worth checking, because plenty of businesses were sold Business Standard to save a few shekels per user and are missing the entire security layer without realising it. The gap between Standard and Premium is almost entirely security, and it is the part that matters when something goes wrong.

Conditional Access: the Control Most Tenants Leave Off

Conditional Access decides who can sign in, from where, and under what conditions. It comes with Entra ID P1, which is part of Business Premium, and in most small tenants it is never configured. You might have MFA switched on through Security Defaults, which is a good baseline, but Conditional Access is far more precise. With it you can require MFA only when a sign-in looks risky, block logins from countries you never do business in, refuse access from devices that are not enrolled and compliant, and shut off the legacy protocols that quietly bypass MFA altogether. For a business whose staff all work from Israel, a single policy that blocks sign-ins from outside the country removes a large slice of automated attack traffic in one move. None of this costs extra. It just has to be set up.

Defender for Business: Real EDR, Already in the Box

This is the feature most owners do not know they have. Defender for Business is endpoint detection and response, the same category of tool we cover in our EDR versus antivirus guide, and it is included with every Business Premium seat. Traditional antivirus matches files against a list of known-bad signatures. EDR watches what programs do, so it can catch an attack that no signature recognises: a process trying to disable security tools, encrypt files in bulk, or reach out to a suspicious server. Defender for Business brings that behavioural detection, automated investigation, and the ability to isolate a compromised machine from the network to a small business without a separate contract. The catch is that it does nothing until you onboard your devices into it. A licence assigned in the admin centre is not the same as an agent running on the laptop. Until the endpoints are enrolled, the EDR you paid for is protecting nothing.

Intune: Managing the Laptops You Cannot See

Intune is device management. It lets you set rules that every company laptop and phone must follow: disk encryption on, a screen lock after a few minutes, a minimum operating system version, and the ability to wipe a device remotely if it is lost or an employee leaves. For an office where people work from home and carry laptops between sites, this is the difference between a lost laptop being an annoyance and a lost laptop being a data breach. It also feeds Conditional Access: once devices are enrolled and reporting compliant, you can refuse Microsoft 365 access to any machine that is not managed. Intune takes real work to roll out properly, which is why it is so often skipped, but it is the piece that turns a scattered set of personal-feeling laptops into a controlled fleet.

Safe Links, Safe Attachments, and the Anti-Phishing Layer

Business Premium includes Defender for Office 365 Plan 1, which sits on top of the basic email filtering everyone gets. Safe Attachments opens incoming attachments in an isolated sandbox before delivery, so a malicious file detonates there rather than on an employee's PC. Safe Links rewrites URLs in emails and Office documents and checks them at the moment someone clicks, which matters because a link that was clean when the mail arrived can be weaponised hours later. There is also impersonation protection that flags messages pretending to come from your managing partner or your finance lead. These policies are not fully switched on by default, and the impersonation protection in particular needs you to tell it which people and which domain to guard. Configured properly, this layer catches a meaningful share of the phishing that is the usual first step in both ransomware and invoice fraud.

Data Loss Prevention: Stopping the Accidental Leak

Purview Data Loss Prevention, also included, watches for sensitive information leaving the organisation and can warn or block when it does. You can set rules so that a message containing what looks like a credit card number, an Israeli ID number, or a bank account is flagged before it is sent to an outside address. For a finance office or a clinic, this guards against the everyday accident more than the deliberate attack: the employee who replies to the wrong thread, or attaches the wrong spreadsheet. It will not police everything, and the rules need tuning to your actual data so they do not raise false alarms, but it is a control most SMBs do not realise they are entitled to.

Self-Service Password Reset and the Move Toward Passwordless

Entra ID P1 also brings self-service password reset, which lets staff securely reset their own passwords after verifying their identity, cutting both help-desk load and the risky habit of writing passwords down. Combined with the authenticator app, it is a step toward passwordless sign-in, where a phone approval or a passkey replaces the password entirely. That is not just more convenient, it removes the thing attackers most want to steal. It is a smaller feature than EDR or Conditional Access, but it is easy to enable and it takes friction out of the more important controls.

Why All This Sits Unused

None of these features are obscure, so why are they so often dark? Part of it is that Microsoft ships them off or half-configured by design, so the tenant works on day one without forcing anyone through security setup. Part of it is that the value is invisible: an owner sees email working and assumes the security is working too, because nothing has obviously broken. And part of it is simply that switching these on well takes time and know-how that a business without in-house IT does not have to spare. The result is common and quietly expensive: a business paying the Premium price while running with Standard-level protection.

A Sensible Order to Switch It On

You do not turn all of this on in an afternoon, and you should not try. A sensible sequence starts with the highest-value, lowest-disruption controls and works down. Confirm MFA is enforced for everyone. Set up a baseline Conditional Access policy. Onboard every device into Defender for Business so the EDR is actually running. Enrol those devices in Intune and require compliance. Tune the Safe Links, Safe Attachments, and impersonation policies. Add data loss prevention rules for the sensitive data you actually hold. Each step is a real improvement on its own, so even a partial rollout leaves you better off than the untouched default.

Getting value from what you already own

If your business is on Microsoft 365 Business Premium, the most cost-effective security upgrade available to you is not buying anything new. It is switching on and configuring the protection you are already paying for every month. That is exactly the kind of work NetFortress does for Israeli SMBs: a review of what your licences include, an honest picture of how much of it is actually live, and a prioritised plan to close the gap.
