An alert is the start of an investigation, not the conclusion. When a suspicious message matters, analysts need to understand how it was delivered, what it contained, what it attempted to contact and what evidence should be carried into the wider incident response process.
From alert to evidence
NXG MailInspect On-Prem is a deep-inspection laboratory for security analysts and researchers. It is designed to make suspicious email review deliberate and evidence-driven rather than forcing teams to rely on a single black-box score.
Analysts can examine headers and routing behavior, extract indicators, inspect URLs and attachments, and preserve the context needed to support escalation, containment or threat hunting.
Controlled analysis for dangerous content
Attachments and linked content can be assessed in controlled sandboxed workflows so potentially malicious behavior can be observed without exposing an analyst workstation or production user environment.
Findings can then be converted into IOCs and correlated with existing SOC/SIEM data to determine whether the email was an isolated attempt or part of a broader campaign.
- Header and route forensics
- Attachment and URL analysis
- Sandbox-assisted payload observation
- IOC extraction
- API-based SOC/SIEM correlation
Designed for analysts who need clarity
The purpose of deep inspection is not to create more alerts. It is to increase confidence in the alerts that deserve investigation and provide a technical trail that can be reviewed by security engineers, incident responders, governance teams and auditors.
