Cyber Security

24/7 Protection For Microsoft 365

Most breaches do not start with a broken system. They start with a valid login. Your Microsoft 365 tenant is the front door to your email, files and payments, and most businesses set it up once and never look at it again.

What this protects

The front door to almost everything you run

Your tenant holds your email, your files and the history of every relationship you have. A breach of it is quiet, and it is expensive.

Redirected payments

A hidden mail rule can redirect invoices and payments for weeks before anyone notices. The money leaves cleanly, with the right account details.

Customer trust

A compromised mailbox writes to your customers as you. The confidence that took years to build is what suffers most.

Insurance and obligations

Cyber insurers expect identity controls and monitoring. Being able to show both keeps a claim straightforward.

The attack moved to the identity layer

Ransomware gets the headlines, but the route in is usually a business email compromise. An attacker obtains valid credentials, signs in as a real user from somewhere unexpected, and then quietly sets up an inbox rule to hide the replies. No malware, no antivirus alert, and often weeks before anyone notices a payment has been redirected.

Microsoft gives you the tools to detect this. The problem is that the default configuration is not tuned for a twenty-person business with no security team, and the alerts go somewhere nobody is watching.

We watch the tenant continuously: sign-in risk, impossible travel, mass file downloads, new mail forwarding rules, external sharing changes and administrator role assignments.

What we monitor and harden

Sign-in risk

Failed authentication patterns, impossible travel, unfamiliar locations and legacy authentication attempts.

Mail rule abuse

New forwarding rules, hidden folders and inbox rules created outside a change window: the signature of a BEC compromise.

Admin and role changes

New global administrators, consent grants to third-party apps, and role assignments outside process.

External sharing

Changes to SharePoint and OneDrive sharing settings, and bulk downloads that look like exfiltration.

Baseline hardening

Conditional access, MFA enforcement, legacy protocol blocking and sensible default policies.

Phishing response

A route to report suspicious mail that actually reaches someone who can pull the message from every mailbox.

Hardening applied as standard

  • Multi-factor authentication enforced for every user, with legacy authentication blocked outright
  • Conditional access rules that respond to risk rather than treating every session identically
  • Mail forwarding to external addresses blocked by default, with named exceptions
  • Third-party application consent restricted so a user cannot grant a stranger access to company data
  • Administrator accounts separated from day-to-day user accounts
  • Mobile device access controlled through policy rather than allowed by default

Questions we get asked about 24/7 Protection For Microsoft 365

Microsoft secures the platform. They cannot secure your configuration choices, and they operate a shared responsibility model. They will tell you plainly that tenant misconfiguration is yours. Most tenants we review have at least one significant gap.

An attacker gains access to a mailbox and uses it to redirect payments or extract data. It usually involves no malware at all, which is why antivirus does not stop it and why it stays unnoticed for so long.

Conditional access is tuned to your patterns rather than applied as a blunt instrument. We start in report-only mode where useful, so you can see what would have been blocked before it is.

Alerts are continuous, so unusual sign-in activity or a suspicious mail rule is flagged within minutes rather than at the next quarterly review.

Yes. A firewall sees network traffic. It cannot see someone logging into your tenant from a different country with a stolen but perfectly valid password.
