Service Components
Sender Verification
Verifies senders using SPF, DKIM, and DMARC to prevent spoofing. Exclusion/block lists and policy controls enable granular access management.
Content Analysis
Uses heuristic and signature-based filters plus threat intel to detect malware, spam, and phishing attempts – including malicious URLs.
Policy Enforcement
Automated policies route, tag, or encrypt emails based on content, sender, or risk profile – supporting compliance and secure communication.
How it works
Sender Verification
Standard Email Security starts with strong sender authentication. It enforces SPF, DKIM, and DMARC to validate the origin of inbound emails and prevent spoofing or abuse of your domain. TLS encryption is applied to secure communication channels, ensuring messages are transmitted safely between mail servers. You can define allow/block lists and configure connection policies either at the SMTP layer or through policy-based rules – giving you flexible control over who can send to your users.
Content Analysis
Once emails are accepted, they pass through a multi-layered content inspection engine. This includes signature-based malware detection, heuristic spam filtering, and real-time threat intelligence. The system scans not just attachments but also embedded links and content for signs of phishing, malware, or policy violations. URLs are evaluated in real time, and suspicious messages are tagged or quarantined with clear warnings to users, improving their security awareness.
Policy Enforcement
Every message is evaluated against customizable policy rules. Based on content, sender, or threat level, emails can be routed to quarantine, tagged for archiving, or automatically encrypted. Organizations can set up dynamic policies for departments or individuals – for instance, requiring encrypted delivery for finance-related communications. Policy flexibility allows administrators to enforce compliance and protect sensitive data with minimal manual intervention.
