Entra ID & M365

Identity is the new perimeter

In a cloud and hybrid IT estate, the firewall no longer protects much: the authentication token is what opens the doors. Entra ID is the control plane through which every access to Microsoft 365, Azure and your SaaS applications flows — it is the Tier 0 of your cloud. Most modern compromises start with an identity: phishing, password spraying, token theft, consent granted to a malicious application.

User Internal · B2B guest Device Compliant · managed Entra ID TIER 0 · CONTROL PLANE Conditional Access · MFA · PIM Microsoft 365 Azure SaaS apps authentication token issued

A tenant moves fast: roles assigned "temporarily", applications registered then forgotten, B2B guests piling up, Conditional Access exclusions never reviewed. This silent drift is exactly what an attacker looks for — and what we measure.

Classic attack paths

AiTM phishing

Phishing proxies that capture the session after MFA: only phishing-resistant MFA (FIDO2) holds.

Password spray & legacy auth

Slow attempts on legacy protocols (IMAP, SMTP) that bypass MFA and Conditional Access.

Consent phishing

A malicious application granted durable Graph permissions by the user — no stolen password needed.

Token theft and replay

Tokens exfiltrated from a compromised workstation and replayed elsewhere while still valid.

Privileged role abuse

Standing Global Administrators, nested roles, Conditional Access exclusions: so many escape hatches for the attacker.

Applications & secrets

Long-lived application secrets, service principals holding high-privilege permissions with no owner.

Attack simulator: replay these paths, read-only

EntraGUARD doesn't just measure compliance — it replays 35 of these known attacks against the tenant in strictly read-only mode. Each scenario runs as a kill-chain, tells you whether the path is viable and where it breaks, links to its MITRE ATT&CK technique, and rolls up into a global exposure score out of 100. It turns an abstract « we should be fine » into a concrete list of viable attack paths. See the simulator in the features →

Our approach to Entra ID security

Three phases, as for the on-premises directory: measure the tenant's actual posture with our EntraGUARD tool (318 checks aligned with ANSSI, CIS, SCuBA, NIS2, DORA and MCSB), lock down the control plane — Conditional Access, phishing-resistant MFA, PIM, application governance — then industrialize with automation (PowerShell, Graph API, Logic Apps) so the posture holds over time. Each service opposite covers one step of this trajectory.
