The number on your Microsoft 365 dashboard tells you something. It does not tell you everything.
There is a quiet moment most business owners never have. It goes something like this. Someone opens Microsoft 365. Perhaps they have been setting up a new account, or troubleshooting a Teams problem, or trying to find where the backup settings live. They click somewhere they have not clicked before. And there, sitting in a corner of the Microsoft portal, is a number.
The Microsoft Secure Score.
Maybe it is 42 percent. Maybe it is 71 percent. Maybe it is impossible to tell at a glance what it actually means.
What happens next matters more than the number itself.
What the score is and isn’t
Microsoft Secure Score is a security rating built into Microsoft 365 and Microsoft Defender. It reviews your Microsoft environment, identifies recommended security improvements and assigns a score based on how many you have acted on.
Those recommendations cover a lot of ground. Multi-factor authentication. Admin account settings. Device controls. Email protection. App permissions. Sharing policies. The list goes on.
Complete more of them and the score generally rises. Visibility into your own Microsoft environment matters, especially when most businesses never look at it until something goes wrong.
But here is the part worth understanding – higher score does not mean you are secure. It means you have completed more of Microsoft’s recommended checklist. Those are related, but they are not the same thing.
Why the score is not the whole picture
Some recommendations in Secure Score are not relevant to your organisation. Some require a licence tier you do not have. Some are technically sound but would cause chaos if switched on without proper testing.
And some, if completed exactly as prescribed, would raise your score without touching your most significant real-world risk.
Consider the variety of organisations that run Microsoft 365. A small accountancy firm. A primary school. A care home. A parish council. A building contractor. All of them might sit on similar scores. None of them has the same risk profile.
Different staff. Different data. Different compliance pressures. Different threats.
This is the gap between a number and a plan.
The drift problem nobody warns you about
Here is something Microsoft Secure Score cannot easily show you: what changed last month.
Microsoft 365 is not static. It moves. People join the business and get accounts. People leave, and sometimes those accounts linger. Someone needs temporary admin access for a project, and that access quietly becomes permanent. A guest user is invited in and never shown out. A mailbox forwarding rule gets created. A third-party app gets approved and forgotten.
Microsoft itself adds features. Licence terms change. Default settings shift.
Your Microsoft 365 tenant might have been in reasonable shape twelve months ago. That says very little about where it is today.
Security drifts. Slowly, without announcements, without alarm bells. A slow accumulation of loose ends that attackers find easier to exploit than any dramatic vulnerability.
This is why “we checked it last year” tends to age poorly.
The mechanic behind the dashboard
The most useful way to think about Secure Score is as a warning light on a car dashboard.
You would not ignore it. But the warning light does not fix the car. Someone still has to lift the bonnet, understand what is actually wrong, make the right repair and then keep an eye on it.
That is the harder work and it is where most small businesses hit a wall.
Microsoft 365 is large, technical and full of settings that most staff never see. Admin roles. Guest access. Shared mailboxes. Conditional access policies. App permissions. SharePoint link settings. Mobile device rules. Old accounts that should have been removed years ago.
Attackers are not usually looking for a Hollywood-style breach. They are looking for the one account, the one permission, the one setting that nobody has reviewed for months, and they are patient enough to find it.
Where tools like Octiga and Huntress Managed ISPM fit
Two tools come up regularly when discussing how to manage the work behind the score.
Octiga helps make Microsoft 365 security posture easier to review, manage and report on. Where Secure Score gives you a view inside Microsoft, Octiga helps turn that into something more actionable. This matters particularly when you are responsible for more than one Microsoft 365 tenant. One environment is challenging enough to maintain. Several, with different settings, users, licences and risk profiles, can become very difficult to track without something to bring them together.
Huntress Managed ISPM focuses on identity security posture. It continuously assesses and hardens your Microsoft 365 environment, checking configurations, permissions and account settings against a defined security baseline. But what makes it genuinely useful for small businesses is not the visibility. It is what happens after.
Most organisations already have a list of things that need fixing. The problem is turning that list into action. Someone has to decide which settings to change, understand what those changes will actually do to staff workflows, test them carefully and then make sure nothing drifts back over time. That is where small businesses usually get stuck.
Huntress Managed ISPM is designed to move from awareness to hardening and then keep checking that hardening holds. Drift detection runs within minutes of a change hitting Microsoft logs rather than overnight. And a feature called Learning Mode can show the impact of a policy change before it goes live, which matters for organisations that have been putting off security changes because they are worried about disrupting staff.
Huntress ITDR is another worthwhile consideration. Where ISPM reduces the gaps and misconfigurations that attackers look for, ITDR watches for signs that an attack is already in progress. Suspicious sign-ins. Unusual inbox rules. Token abuse. Rogue apps. Mailbox forwarding changes that quietly redirect emails somewhere they should not go.
Many attacks on Microsoft 365 do not start with malware. They start with a real login using stolen or compromised credentials. Because the attacker may be using a legitimate account, the activity can look normal unless someone is watching closely. For smaller businesses that cannot monitor Microsoft 365 sign-in logs around the clock, ITDR provides that managed watching layer.
Backups
One thing Microsoft Secure Score does not measure is whether your Microsoft 365 data is properly backed up. Microsoft keeps the service running. It does not guarantee your organisation can recover email, files, Teams conversations or SharePoint content if they are deleted, encrypted, overwritten or lost through account compromise. Retention periods and recycle bins can help, but they are not the same as an independent backup that can be restored on a bad day. If you are reviewing Microsoft 365 security, backup should be on the list.
Sensible places to start
If you use Microsoft 365 and have never looked at your security settings closely, these are the most important questions to ask:
Is multi-factor authentication switched on for every user, not just some of them? Are admin accounts properly protected with their own dedicated accounts? Have old staff accounts been disabled and removed? Are guest users regularly reviewed? Are mailbox forwarding rules checked? Are third-party app permissions controlled? Are SharePoint and OneDrive sharing settings set appropriately? Are security alerts being monitored? Is Microsoft 365 data properly backed up? Are settings reviewed on a regular schedule?
None of those questions is particularly dramatic. They rarely produce dramatic answers. But the consequences of leaving them unexamined can be significant.
A compromised Microsoft 365 tenant is not just an IT problem. It can mean client emails exposed. Invoices intercepted or redirected. Teams conversations read by people they were never meant for. SharePoint files accessed or destroyed. Supplier payments redirected. Insurance claims complicated.
For a small business, that lands hard and fast.
The question worth asking instead
Microsoft Secure Score has a role. Ignoring it entirely would be unwise.
But the more important question is not “what is our score?” It is “do we know where our Microsoft 365 risks actually are, and is someone doing something about them?”
The score is a prompt. A useful one. It can start conversations that maybe should have happened years ago.
But it is a starting point, not a destination. The real work is reviewing which recommendations apply to your organisation, understanding what each change would actually do, making the right updates carefully, checking for drift and knowing when to ask for help.
A higher score is a reasonable aim. A Microsoft 365 environment that has been properly reviewed, hardened and kept under regular watch is a better one.
