Business Email Compromise (BEC) Security and Consulting Services

Strengthen identities. Detect account takeover. Respond with confidence.

Business email compromise (BEC) is more than a malicious message. Attackers can exploit trusted accounts to impersonate colleagues, redirect payments, and access sensitive information. Avertium helps you reduce that risk by combining stronger identity and email defenses, security validation, and continuous detection and response.

PROTECTION BEYOND THE INBOX

Strengthen your first line of defense

Close gaps in Microsoft 365 and Entra ID configurations, including Conditional Access, phishing-resistant multifactor authentication, application permissions, and mailbox forwarding controls. Turn available security capabilities into practical protections that make accounts harder to compromise.  

  • Microsoft Workshops: Learn how to address identity and email protection, Conditional Access, and safer access practices in your Microsoft environment. Learn about workshops.

  • Microsoft Security Baseline Assessment: Identify identity, email, and access-control configuration gaps and prioritize remediation. Learn about the assessment.

  • Microsoft E5 Configuration and Optimization: Configure and strengthen available Microsoft security capabilities. Learn about E5 optimization. 
Validate Defenses Before Attackers Test Them

Identify exploitable identity weaknesses and test BEC detection logic through targeted assessments and simulated attacks. Understand where controls need improvement and whether suspicious activity produces actionable alerts.

  • Microsoft Adversary Assessment (MAA): Validate that simulated BEC activity produces the expected telemetry, correlated detections, and actionable alerts. Learn about MAA.

  • Social Engineering Assessment: Test susceptibility to phishing and impersonation while evaluating identity controls and security awareness. Learn about Social Engineering Assessment. 

  • Purple Team Engagement: Validate and refine detection and response through collaborative, real-world attack simulations tailored to your environment. Learn about Purple Team.
