Microsoft Entra ID Security Monitoringfor UK Businesses
Over 90% of UK cyberattacks start with a compromised identity. Microsoft Entra ID (formerly Azure Active Directory) is the authentication backbone of your Microsoft 365 environment — and the primary target for attackers. Gridisys monitors every Entra sign-in event, every role change, every MFA modification, 24/7, with AI detection and human analyst review.
What Gridisys Monitors in Your Entra ID Tenant
We connect to your Microsoft Entra ID via read-only Graph API permissions and ingest every identity event log — processing them through our AI detection models in near real time.
Attack Vectors We Stop
Compromised Password Sign-Ins
Attacker uses credentials from a dark web breach to sign into your Microsoft 365. Gridisys detects the anomalous device fingerprint and geolocation instantly.
Impossible Travel
Your CFO signs in from London at 9am, then Beijing at 9:15am. Gridisys flags the second sign-in as impossible travel and escalates to a human analyst within 30 seconds.
MFA Bombing / Fatigue Attacks
Attacker repeatedly pushes MFA approval requests hoping the user taps 'Approve' by mistake. We detect the pattern and alert before access is granted.
Global Admin Privilege Abuse
An attacker or insider quietly adds Global Administrator rights to a low-privilege account. Gridisys catches every Entra ID role assignment change in real time.
Conditional Access Policy Bypass
Attackers probe for gaps in Conditional Access policies — legacy auth protocols, unmanaged devices, compliance exceptions. We flag every bypass attempt.
Suspicious OAuth App Consent
Consent phishing tricks users into granting malicious apps access to email, calendar, and OneDrive. We monitor every OAuth grant across your Entra tenant.
