MDR for Microsoft 365
Your email, identities and files now live in Microsoft 365—and that is exactly where attackers go first. TTG’s Managed Detection & Response watches your Microsoft 365 tenant around the clock, spots the sign-in that should not have happened, the inbox rule nobody created and the login from the other side of the world, and steps in to shut it down. You get a security team watching Entra ID, Exchange Online, SharePoint, OneDrive and Teams every hour of every day—without hiring one.

Why MDR for Microsoft 365
Microsoft 365 is where your business runs—and where attacks begin.
Most breaches today do not start with malware on a laptop. They start with a stolen Microsoft 365 password—phished, bought or guessed—used to quietly read email, set up a hidden forwarding rule and send invoices from a name your customers trust. The built-in security signals are already there inside Microsoft 365. What is usually missing is someone watching them, day and night, who can act the moment they add up to a threat. That is what MDR gives you.
With TTG-managed MDR for Microsoft 365
- Continuous monitoring of Entra ID, Exchange Online, SharePoint, OneDrive and Teams
- Compromised sign-ins caught and acted on by our engineers—not left sitting in an alert queue
- Hidden forwarding rules, risky OAuth apps and data theft surfaced before the damage spreads
- Guided or hands-on remediation and a clear monthly report on what we saw and did
What we detect & respond to
The Microsoft 365 attacks we are built to stop
Account takeover
Stolen or compromised credentials used to log in as one of your people—caught by the behavior that gives an intruder away, not just the password.
Business email compromise
Fraudulent invoices, wire-transfer requests and vendor impersonation sent from a real, trusted mailbox inside your own tenant.
Phishing & malicious links
Credential-harvesting pages and weaponized attachments aimed at your users, flagged and followed up the moment someone takes the bait.
Impossible-travel & risky sign-ins
A login from Houston and another from overseas minutes later, sign-ins from anonymizing networks, and other sign-in risk Entra ID surfaces.
MFA fatigue attacks
A flood of push prompts sent until a tired user finally taps approve. We spot the pattern and cut the attacker off before that happens.
Malicious inbox & forwarding rules
Hidden rules that auto-forward, delete or hide mail—a classic sign an intruder is covering their tracks inside a mailbox.
OAuth app abuse
Rogue or over-permissioned apps consented into your tenant that quietly read mail and files long after a password is changed.
Data exfiltration
Unusual mass downloads or sharing out of SharePoint and OneDrive that signal data being pulled out of your business.
Privilege escalation
An ordinary account suddenly granted admin rights or added to a privileged role—often the step right before real damage is done.

What’s included
Detection and response, delivered by our team
Microsoft-native integration
We work with the security you already pay for—Microsoft Defender for Office 365, Defender for Cloud Apps and Entra ID Protection—so there is no rip-and-replace.
24/7 monitoring
Continuous eyes on Entra ID, Exchange Online, SharePoint, OneDrive and Teams—so suspicious activity never waits until morning to be seen.
Threat hunting
Our analysts go looking—proactively chasing down the quiet signs of compromise that automated alerts alone tend to miss.
Alert triage & investigation
We separate the real threats from the noise, investigate what matters, and reach out with a plain-English picture of what happened and what to do.
Guided & hands-on remediation
When a threat is confirmed we help you contain it—or, with your go-ahead, step in directly to revoke sessions, reset access and remove the attacker’s foothold.
Risk policies & monthly reporting
We help tune user and sign-in risk policies so Microsoft 365 defends itself better over time, and report each month on what we saw, caught and resolved.
How it works
From onboarding to round-the-clock coverage
- Connect We integrate securely with your Microsoft 365 tenant and its built-in security signals—no new agents on every device, no disruption to your users.
- Baseline We learn what normal looks like for your organization—who signs in from where, on what, and when—so unusual activity stands out clearly.
- Detect & hunt Our team watches continuously and hunts proactively, correlating sign-ins, mailbox activity and app behavior into high-confidence detections.
- Respond & report We contain confirmed threats—guided or hands-on—keep you informed, and review coverage and findings with you on a regular cadence.
Email, identity and endpoints
Cover the whole attack path, not just one piece of it
MDR for Microsoft 365 protects your cloud identities, email and files. Our Managed Detection & Response extends that same watch to your laptops and servers, and SIEM ties every log together into one correlated view. Most clients run them together so a stolen password in the cloud and the malware it drops on a device are caught as one connected story—not two separate alerts nobody links. We will recommend the right mix for your size, risk and budget, never more than you need.
Microsoft 365 MDR, answered
How is this different from the security built into Microsoft 365?
Microsoft 365 generates the signals; MDR is the team that watches and acts on them. Defender and Entra ID Protection raise alerts, but someone still has to triage them, investigate the real ones and respond fast, at any hour. That is the part we provide—so your built-in security actually gets used.
What Microsoft 365 licensing do we need?
It depends on the plan you are on today. In a free consultation we review your current Microsoft 365 licensing and show you what is already covered and where a step up unlocks stronger detection—so you spend on what genuinely improves your security, and nothing you do not need.
Will this get in our users’ way?
No. MDR watches the activity Microsoft 365 already records—there is nothing for your team to run and no slowdown to their day. They simply get a safer environment, and only hear from us if we need a decision.
What happens when you find something?
We investigate, confirm whether it is a real threat, and contain it—revoking sessions, resetting access and removing malicious rules or apps—either by guiding your team or, with your go-ahead, acting directly. You get a clear account of what happened and how we stopped it.
