What Secure Score actually measures
When a business decides to improve its cyber security, the conversation often turns quickly to new software: another platform, another licence, another monitoring service. Sometimes that is the right answer. Before buying, there is a simpler question. How well is the Microsoft 365 environment you already pay for configured?
Microsoft Secure Score is a useful place to start. It sits in the Microsoft Defender portal and reviews supported settings across identities, devices, apps and data, depending on the services you use. A higher number means more of Microsoft's recommended actions have been taken.
The number matters less than what sits behind it: a list of recommended actions, the points each one is worth and guidance on what making the change involves.
The gap is often configuration, not products
An organisation can hold Microsoft 365 Business Premium or an enterprise subscription and still have important controls switched off or only partly applied. The features needed to close those gaps may already be included. What is often missing is the time to plan each change, test it and keep it maintained.
A first review commonly raises questions like these.
- Are some accounts signing in without multifactor authentication?
- Do more people have administrator rights than need them?
- Are device protection policies applied to every laptop, or only some?
- Has anyone reviewed how files are shared outside the organisation recently?
Don't chase the number
Microsoft states that Secure Score is not an absolute measure of how likely you are to be breached. A perfect score is not the goal, and a high one does not prove that an environment is secure.
Some recommendations will not suit your organisation. Others need a licence you do not have, or would disrupt how people work. Secure Score lets you record that: an action can be marked as planned, risk accepted, resolved through a third party or resolved through alternate mitigation. Microsoft cannot see whether that alternative is really in place, so those statuses are only as reliable as the person setting them.
For each action, ask three questions. Does it reduce a risk that matters to us? Do we have what we need to apply it? Who will it affect, and how? Where the answer means you will not apply it, write down why and what protection you rely on instead.
Turn the recommendations into a plan
Record today's score and the date, then choose the handful of actions most relevant to your business. Weak sign-in protection, broad administrator access and unmanaged devices usually come first.
Give each action an owner and a target date. Test changes with a small group before applying them to everyone, so a well-meant policy does not lock people out on a Monday morning.
Review progress monthly. The score may rise, but the more useful findings are settings that have slipped back, actions still waiting and risks the business has knowingly accepted. That turns a number into a short, honest account that management can follow.
Before you buy anything else
Secure Score will not replace vulnerability testing, incident planning, recovery testing or staff awareness, and it covers Microsoft's own controls rather than everything you run. What it does well is show where protection you have already paid for is not yet doing its job.
Use it to establish what is configured, where the gaps are and whether an existing feature could close them. Then you can decide what to change, what needs ongoing management and whether anything genuinely needs buying.
