How to reach a 75% Microsoft Secure Score (and why that is the sweet spot)
Most business owners have never opened their Microsoft Secure Score, and the ones who have usually came away with a vague sense of guilt about the number staring back at them. That reaction is understandable, but it misses the point. Secure Score is not a report card that judges you. It is a map that shows you where the obvious gaps are and, just as usefully, which ones are worth closing first. Once you understand how to read it, that single percentage becomes one of the most practical planning tools you own.
What the number actually measures
Microsoft Secure Score is a built-in measurement inside your Microsoft 365 tenant. It reads your current settings, compares them against a long list of recommended security actions, and gives you a percentage that reflects how many of those recommendations you have put in place. The score spans several areas of your environment, including the identities your staff sign in with, the devices they work on, and the apps and data they handle every day.
There are two things every owner should understand about how it works. The first is that it measures configuration, not outcomes. You earn points for switching on a protection such as multi-factor authentication, not for whether you have avoided a breach. The second is that the number is relative rather than absolute. It tells you how far you have travelled along Microsoft's recommended path, not whether you have arrived at a place that is safe enough for your particular business. That distinction matters, because it explains why the goal is steady, sensible progress rather than a perfect result.
It also explains why the score can move on its own. Microsoft periodically adds new recommendations, adjusts how existing ones are counted, and changes the maximum points available. A score that drops one month is not always a sign that something has gone wrong. More often it means the goalposts shifted, and a quick look at the history view will tell you exactly what changed and why.
Why 75% is the target, not 100%
If configuration earns points, you might reasonably ask why anyone would stop short of a perfect score. The answer is that the last stretch of the journey rarely delivers value that matches the effort. Many small businesses start somewhere in the 30 to 45 percent band, which is roughly what a set of default settings will earn you. The climb from there into the seventies comes from a handful of high-impact changes that genuinely reduce your risk. Pushing beyond that point tends to involve recommendations that require licences you may not hold, features for workloads you do not use, or controls that duplicate protections you already have in place through other means.
Security should always be balanced against the way your team actually works, and not every recommendation will suit your environment. Chasing points for their own sake can quietly make life harder for staff without making the business meaningfully safer. A sustained score in the mid-seventies signals that the settings that matter most are switched on, while leaving room to ignore the recommendations that would cost you more in friction than they return in protection. It is a strong, honest position, and crucially it is one you can hold onto month after month.
The changes that move the needle
The good news is that most of the distance to 75% is covered by a short list of identity-focused actions, and these are the same controls that stop the attacks small businesses actually face. Rather than working down the ranked list from the top, it is far more effective to start where the real risk lives.
Multi-factor authentication is the single most valuable change you can make, and it is worth doing first for your administrators and then for everyone else. It neutralises the overwhelming majority of attacks that rely on a stolen password, because knowing the password is no longer enough to get in. Alongside it, blocking legacy authentication closes an old back door that quietly bypasses MFA altogether. Older sign-in protocols were never built to support modern verification, and attackers lean on them precisely because they slip past the controls you thought you had in place.
From there, a small number of supporting changes round out the picture. Setting up self-service password reset reduces the load on whoever handles your IT while strengthening your identity posture. Turning on audit logging gives you a record of what happened if you ever need to investigate an incident. Conditional Access rules add a layer that weighs up the location, device and risk of each sign-in before granting access. Each of these is a modest task on its own, and together they carry you comfortably into the range that indicates a well-protected tenant.
Treating the score as a habit, not a project
The businesses that get the most from Secure Score are the ones that stop treating it as a one-off cleanup and start treating it as a regular check-in. A short monthly review is enough to catch a new recommendation, spot a setting that has drifted, and confirm that the protections you rely on are still doing their job. Because the score is expressed as a single figure that trends over time, it also gives you something genuinely useful to show clients, insurers and regulators when they ask how seriously you take security. A steady upward line is a simple, credible way to demonstrate that your defences are improving rather than standing still.
Reaching 75% is well within reach for almost any small business, and it rarely requires new spending so much as switching on protections you are already paying for. If you would like a hand reading your own score and turning it into a short, prioritised plan, that is exactly the kind of work I do every day. The number is only the starting point. What matters is the handful of sensible changes behind it, and the quiet confidence of knowing the obvious doors are closed.
