Microsoft 365 sits at the centre of most recruitment businesses now.
For many agencies, the entire working day runs through that one platform.
That leads to a quiet assumption:
“We are on Microsoft 365, so we are safe.”
On one level, the logic feels fair. This is Microsoft. Big, trusted, heavily audited. If something serious was wrong with default settings, surely everyone would talk about it.
Here is the problem.
Microsoft 365 gives you excellent security features, but the starting point favours ease and collaboration, not strict lockdown. Default settings help staff get up and running quickly. They do not line up with what a UK recruitment firm needs if you care about access, candidate data and client trust.
Unless someone takes time to configure, monitor and adjust those settings, your agency carries more risk than you think.
Microsoft wants new tenants to feel smooth and low friction.
Share a file with a colleague.
Open a document on a laptop at home.
Join a Teams call from a phone.
All of that works well with very few clicks.
Under that smooth experience sit choices about security. Those choices matter for a business that holds personal data and client information.
For example:
None of this means “Microsoft 365 is insecure”. It means the platform expects someone in your world to take ownership and align settings with your risk.
A few areas show up again and again when we review new environments.
Microsoft recommends MFA, especially for admin accounts.
Default behaviour does not force that choice. Many tenants still allow username and password alone on critical accounts.
For a recruiter, that means one stolen password stands between an attacker and email, files and Teams.
Older Office apps still support “legacy authentication”.
This method does not work with MFA and suits brute‑force attacks and credential stuffing. Modern guidance pushes towards disabling legacy auth, yet plenty of environments keep it running because nobody wants to risk disruption.
Attackers look for the path of least resistance. Legacy auth offers exactly that.
Default sharing tends to favour getting work done.
“Anyone with the link” often feels easier than restricting access. External recipients open documents with no friction. That is helpful for speed and dangerous if staff share the wrong content in the wrong way.
For a recruitment agency, that might include candidate IDs, right‑to‑work documents, salary information or client terms floating around in public links.
To answer “who accessed this” or “where did this sign‑in come from”, you need audit logs.
Plenty of tenants either start without those logs enabled or never look at them after day one. When something odd happens, there is nothing to review or nobody assigned to check.
Microsoft 365 includes data loss prevention (DLP), retention controls and compliance tools.
In many SMEs, those features sit unused or run on broad, untuned rules that bear no relation to real working patterns. Valuable data then leaves through email or file sharing with no meaningful checkpoints.
Microsoft provides a Secure Score inside the tenant.
That score reviews configuration and highlights weaknesses, along with suggestions for workload priorities.
Many agencies do not open that page. Others glance once and never return. As a result, security posture drifts and nothing prompts a structured review.
A pattern appears if you step back.
The platform gives access to good security features.
Licences include options for MFA, conditional access, device compliance, role control and more.
Protection only arrives when those options are shaped around your business.
Security is not “we have Microsoft 365 Business Premium, so we are sorted”.
Security is:
Threats move. Compliance duties change. Microsoft shifts product behaviour. One security review five years ago does not hold up in 2026.
Many recruitment owners assume Microsoft 365 “runs itself”.
Strong platform.
Strong brand.
Strong marketing.
Day to day, what happens looks different.
Email alerts build up without review.
Logs exist without anyone reading them.
An IT person in the business spends most time on onboarding, leavers, laptop issues and user questions. Security sits on the same plate as everything else.
Risk grows in those gaps.
Not because people do not care.
Because nobody has clear space to ask “what changed in our tenant this quarter” or “which settings still match how we work now”.
This is why SMEs often bring in a Microsoft 365 partner.
Not because the platform is beyond reach.
Because owners value someone who lives in this detail every day while they focus on clients, candidates and growth.
A good partner will:
Think of this like a building manager.
You still own the building.
You decide who works there.
Someone else checks locks, exits, alarms and lights as a routine job.
Microsoft 365 remains one of the strongest platforms for productivity and security, especially for recruitment SMEs.
That strength only translates into protection when there is clear ownership around configuration, review and day‑to‑day monitoring.
Default settings favour easy sharing and fast setup. Those same defaults open doors that attackers know how to find.
If you have not looked under the hood of your tenant in a while, or if your view of risk starts and ends with “we are on Microsoft 365, so we are fine”, this is a good moment to pause.
Security here is not about fear. It is about control and confidence.
A short review now is far cheaper than rebuilding trust with a client who asks “who else had access to our data” and you do not have a clear answer.
