What is Active! zone SS?

Active! zone SS is a targeted email attack countermeasure service equipped with an email sanitization system and features to enhance user awareness.
With functions such as macro removal in attachments, image conversion, separation/sanitization, display of sender country, and converting HTML emails to text, it enables users to notice dangerous emails before opening them.

Main functions of Active! zone SS

Functions		More Details
	Removal of Macros in Attachments	Removes macros and re-attaches the file for distribution, eliminating malicious macro-based threats.
	Converting Attachments to Images	Displays attachments as images in the browser before opening. Users can check the content in advance to determine whether the file is legitimate, significantly reducing risk.
	Attachment separation/download	Delivers attachments separately from the email. Users can view/confirm files via a one-time URL before downloading. Password-protected ZIP files can be decrypted for file confirmation.
	Display sender's country name	Displays (using national flags) where the email came from and which countries it passed through before downloading.
	Convert HTML emails to plain text	Removes tags contained in HTML emails and converts them into text.
	Duplicate detection for received emails	Duplicates incoming email and delivers it to a different email server on a separated network. If you have split communication routes according to security policy, this eliminates the need to check two mailboxes.

Features of Active! zone SS

1. Intuitive and Easy-to-Understand Policy Configuration Screen

Set inbound policies (processing conditions) with different requirements for each department/team, and execute actions such as macro removal and attachment image conversion/separation. Settings use an easy-to-check flowchart format.

2. Visualizing threats from email attack characteristics

Displays country flags for email transit route, attachment image conversion indicators, signal displays for virus scan results, color-coded display when header From and envelope From differ, etc.—to promote awareness even for users with low IT literacy.

Display sender's country name
It is possible to automatically insert the delivery route into the email body and add warning text to notify users.

Signal display of virus scan results

3. Separates files from emails for verification and sanitization before downloading

Malware such as Emotet is often sent hidden in encrypted ZIP files, which typical antivirus cannot handle. Active! zone SS decrypts password-protected attachments and also detects their contents.

Sandbox Plan for stronger Emotet countermeasures

A sandbox is a system that can perform behavior detection by executing files in an isolated environment and checking them based on behavior. In Active! zone SS, files judged dangerous by the sandbox cannot be downloaded by users.

Even against Emotet, which is sent via password-protected ZIP files and spreads infection by evading sandbox detection, decrypting in the browser enables detection by the sandbox and prevents infection.
