Secure your Microsoft environment against how attackers really operate.
Avertium’s Microsoft Adversary Assessment (MAA) is an adversary emulation security assessment that tests how real attackers could compromise Microsoft Entra ID, Microsoft 365, and (when in scope) on‑premises Active Directory - and if you would see them. We validate realistic attack paths, confirm security visibility, and deliver prioritized remediation aligned to compliance and business risk.
Avertium emulates real Microsoft attacker tactics, such as identity abuse, OAuth misuse, token theft, privilege escalation, and hybrid attack chains, then proves whether your controls detect and stop it. You get evidence‑based attack paths and a practical remediation plan, not a generic findings list.
Validated attack paths across Entra ID, Microsoft 365, and hybrid AD environments—not isolated findings
Manually validated exploitability with proof using real attacker techniques and controlled execution
Visibility Reports showing which identity attacks were detected, logged, or missed
Executive-ready summary translating identity risk into business impact
Prioritized remediation plan focused on breaking the highest‑risk attack chains first
MAA uses a structured adversary emulation approach to validate how Microsoft identity and cloud environments behave under real attacker pressure, testing feasibility, visibility, and response effectiveness with clear guardrails. :
Phase 1: Confirm scope and rules - Align on objectives, rules of engagement, in-scope tenants/domains, and comms/escalation paths.
Phase 2: Map external exposure (OSINT) - Identify exposed identity/M365 signals and likely entry points (internet-facing assets, branding, credential-leak leads).
Phase 3: Assess identity posture - Review Entra ID/M365 roles, permissions, and configs; flag misconfigurations that enable realistic attack chains.
Phase 4: Simulate access - Execute agreed techniques to validate initial access and escalation within safety constraints.
Phase 5: Test assumed breach (if in scope) - From a trusted-network position, assess on-premises AD paths to privilege escalation and domain compromise.
Phase 6: Validate visibility - Confirm key actions generate expected telemetry/detections (audit logs, SIEM/XDR); document gaps. Hold weekly debriefs before reporting.
Phase 7: Deliver reports and next steps - Provide external/internal reports, visibility findings, and prioritized remediation recommendations; run a readout to align.
Get clarity on how attackers could compromise your Microsoft environment—and a focused plan to fix what matters most.
