Business Email Compromise Defense

Stop Wire Fraud. Eliminate the Access Paths BEC Attackers Exploit.

THE PROBLEM

Traditional Email Security Can’t Stop BEC
Because It Can’t See What Compromised
Accounts Can Access

Business Email Compromise has evolved beyond email impersonation. Modern BEC campaigns compromise executive and finance team accounts, then leverage legitimate access to financial systems, vendor portals, and approval workflows – executing wire fraud before security teams realize what’s happening.

Email authentication can't stop attacks using legitimate accounts

Email authentication protects against spoofing but can't stop attacks from compromised legitimate accounts with valid credentials.

Identity tools can't show financial system exposure

IAM detects suspicious logins but can't reveal how compromised accounts access payment platforms to execute unauthorized wire transfers.

Manual access reviews can't keep pace with BEC evolution

There is now an overabundance of policy and posture configuration that changes too quickly to manage it all manually or in narrow silos. Adopting CSMA principles will provide opportunities for tools to carry out some functions more autonomously.

THE SOLUTION

Mesh CSMA: Break BEC Attack Paths
to Financial Systems

Mesh reveals and eliminates the access paths from compromised accounts to payment systems and financial assets.

1. Map Every Path from Executive Accounts to Financial Systems

Mesh traces complete attack chains showing how compromised executive and finance identities could access payment platforms.

2. Prioritize Based on Financial Impact and BEC TTPs

Mesh correlates BEC threat intelligence with your environment to show which compromised accounts could execute fraud.

3. Eliminate High-Risk Financial Access Paths Systematically

Mesh orchestrates remediation to remove unnecessary financial access and enforce approval workflows before exploitation.

THE OUTCOMES

Stop BEC Before Wire Transfers.
Not After.

See and eliminate complete post-phishing attack paths before attackers find them

See complete BEC attack paths to financial systems

Mesh reveals exactly how BEC attackers would exploit compromised accounts: CEO email compromise + payment platform access + vendor portal admin + approval workflow bypass = unauthorized $500K wire transfer. All systems. One view.

Answer the question: "If this executive is compromised, what financial damage could occur?"

Mesh maps the financial blast radius for every high-value identity – showing which compromised accounts could authorize payments, modify vendor details, or execute wire transfers without additional approval.

Prioritize financial access controls based on actual BEC risk

Stop reviewing all financial access equally. Mesh shows which accounts and permissions actually create paths to execute fraud, so you focus on the access rights that pose real financial risk.

Enforce least-privilege access to payment systems

Mesh identifies and helps eliminate unnecessary access to financial platforms, payment approval workflows, and vendor management systems – reducing BEC attack surface before accounts are compromised.

Validate BEC defenses beyond email authentication

Stop measuring BEC defense by DMARC compliance alone. Mesh continuously validates what compromised accounts could actually do with legitimate access – showing whether your controls prevent financial fraud even after compromise.

Respond faster with pre-mapped financial system exposure

When a BEC incident occurs, Mesh instantly shows which financial systems the compromised identity can access, which payment workflows are at risk, and where to prevent fraud – eliminating hours of manual investigation during critical response windows.

What is Automated Security Control Assessment (ASCA)?

What is Automated Security Control Assessment? Automated Security Control Assessment (ASCA) is the continuous, machine-driven process of testing, validating, and verifying that an organization’s security controls are configured correctly, operating as intended, and actually capable of stopping the threats they were designed to prevent. Rather than relying on periodic manual audits or point-in-time pen tests, […]

Security Analytics and Intelligence Layer (SAIL): SAIL’s Role in CSMA

Security teams today aren’t short on data. They’re drowning in it. The average enterprise operates 83 security tools across 29 vendors. Each one generates alerts, scores, and findings – a flood of signals that no team can meaningfully process. And yet, despite all of this instrumentation, 67% of breaches are still missed by internal teams. […]

The Five Layers of CSMA (Cybersecurity Mesh Architecture)

The Five Layers of CSMA: A Guide for Enterprise Security Teams The average enterprise today deploys 83 security tools across 29 vendors. And yet, less than half of breaches are detected by internal teams. More tools haven’t translated to better security – they’ve produced more dashboards, more alerts, and more noise, without answering the question […]
