Helping your clients build stronger Microsoft 365 security

For many businesses, Microsoft 365 has become the centre of everything.

Emails.

Teams.

SharePoint.

OneDrive.

User identities.

Business-critical data.

That also makes it one of the first places cyber criminals look when targeting an organisation.

As an IT provider, protecting your clients isn't just about supplying Microsoft 365. It's about helping them secure it properly.

The good news is that there are practical improvements every client can make before investing in additional security solutions.

Start with the fundamentals

Before introducing additional security services, encourage clients to review the basics.

Enable Multi-Factor Authentication

MFA remains one of the most effective ways to protect Microsoft 365 accounts from compromise.

If credentials are stolen through phishing, MFA provides another layer of defence.

Remove unnecessary administrator access

Many businesses have more administrator accounts than they actually need.

Encourage clients to limit privileged access to those who genuinely require it and avoid using admin accounts for everyday work.

Review user permissions

Businesses change constantly.

Employees join.

People leave.

Departments evolve.

Regularly reviewing user access helps reduce unnecessary risk and supports good security practice.

Keep devices updated

Microsoft 365 is only one part of the security picture.

Encourage clients to keep Windows, browsers, firmware, and applications fully patched to reduce exposure to known vulnerabilities.

Turn on Microsoft's built-in security features

Many Microsoft 365 tenants include security settings that are never enabled.

Helping clients make use of Microsoft's built-in protections is often one of the quickest security wins.

Building a stronger Microsoft 365 security stack

Basic security provides a strong foundation.

But today's threats often require continuous monitoring, better visibility, and multiple layers of protection.

Here are some of the services partners can introduce to strengthen their clients' Microsoft 365 environments.

Microsoft 365 MDR

What it provides

Microsoft 365 MDR delivers around-the-clock monitoring of Microsoft 365 environments.

Security analysts investigate suspicious activity, detect threats early, and respond quickly if accounts or identities become compromised.

A great fit for clients who:

• Want 24/7 monitoring

• Lack an internal security team

• Need faster threat detection and response

Microsoft 365 Tenant Protection

What it provides

Microsoft 365 Tenant Protection continuously assesses Microsoft 365 configurations against security best practice.

It identifies misconfigurations, risky permissions, identity weaknesses, and security gaps before they become larger problems.

A great fit for clients who:

• Want greater visibility

• Need ongoing security posture management

• Are concerned about configuration drift

IRONSCALES Email Security

What it provides

Email remains the primary route for cyber attacks.

IRONSCALES enhances Microsoft 365 by detecting sophisticated phishing attacks, removing malicious emails, and helping organisations respond more quickly when threats are identified.

A great fit for clients who:

• Receive large volumes of email

• Are concerned about phishing

• Want an additional layer beyond Microsoft 365 protection

Microsoft 365 Backup

What it provides

Accidental deletion, ransomware, malicious insiders, and human error can all affect Microsoft 365 data.

Microsoft 365 Backup provides independent protection for Exchange Online, OneDrive, SharePoint, and Teams, allowing businesses to recover data quickly if required.

A great fit for clients who:

• Depend heavily on Microsoft 365

• Need faster recovery

• Want greater resilience

DNS Filtering

What it provides

DNS Filtering blocks access to malicious websites before users connect to them.

It helps prevent phishing, malware downloads, command-and-control communications, and other web-based threats.

A great fit for clients who:

• Have remote workers

• Want another proactive layer of defence

• Need consistent protection across devices

Layered security creates better outcomes

No single product stops every attack.

The strongest Microsoft 365 environments combine good security practices with multiple protective layers.

For partners, that creates an opportunity to deliver more value, strengthen client relationships, and build recurring security services around one of the most important business platforms your clients use every day.
