Email remains the most exploited attack vector in modern cybersecurity. More than 90% of successful cyberattacks begin with an email, making phishing, ransomware delivery, credential theft, and Business Email Compromise (BEC) among the most significant risks facing organizations today.
Attackers continuously target employees, executives, finance teams, HR departments, and IT administrators through sophisticated phishing campaigns, malicious attachments, fake invoices, credential harvesting pages, and domain impersonation.
NuageSec's Email Security Assessment Services help organizations identify weaknesses across Microsoft 365, Google Workspace, Exchange Online, Secure Email Gateways, email authentication protocols, user awareness, and security configurations to reduce the risk of email-based cyberattacks.
An Email Security Assessment is a comprehensive evaluation of your organization's email infrastructure, authentication mechanisms, mail flow security, user protection controls, and monitoring capabilities.
The assessment identifies vulnerabilities that attackers commonly exploit to deliver phishing emails, compromise user accounts, spoof trusted domains, distribute malware, and bypass email security controls.
Email continues to be the preferred attack vector because it directly targets people rather than technology.
Our assessment identifies weaknesses across enterprise mailboxes, identity configurations, routing, and user reporting:
While email penetration testing evaluates active exploit entry paths, our assessment evaluates complete configuration parameters and policy controls.
| Feature | Email Penetration Testing | Email Security Assessment |
|---|---|---|
| Primary Objective | Simulates active email threats and attacks | Evaluates overall email configurations and security posture |
| Evaluation Focus | Offensive execution and threat delivery paths | Defensive policies, identity controls, and DNS records |
| Assessment Scope | Targeted to test individual routing points | Comprehensive analysis covering people, processes, and tech |
| Core Outcome | Identifies exploitable vulnerability bypasses | Delivers long-term configuration hardening roadmaps |
| Analysis Style | Technical execution checks (e.g. spoof deliveries) | Strategic configuration review and alignment checks |
NuageSec evaluates traditional mail routing, DNS authentication, and secure email gateway policies.
