m-FILTER vs Active! gateSS Comparison: Everything You Need to Know Before Choosing

Active! gateSS is a Japanese email security service from QUALITIA designed to prevent accidental transmission of emails to the wrong recipients, a leading cause of information leakage in Japanese organisations. Misaddressed emails, incorrect attachments and careless use of carbon copy fields can expose personal data and confidential business information, leading to regulatory, contractual and reputational consequences. Active! gateSS addresses this risk by intercepting outbound messages and applying checks and controls before they leave the organisation. Its approach combines user-level confirmation prompts with administrator-defined policies, creating a safety net that works regardless of which email client employees use and without requiring significant changes to existing workflows. As a cloud service, it can be introduced relatively quickly alongside platforms such as Microsoft 365 and Google Workspace. These safeguards are designed to reduce human error at the moment of sending, which is where most accidental disclosures actually occur in practice. Key capabilities include temporary holding of outgoing mail so senders can review and cancel messages, confirmation screens that highlight external recipients and attachments, and approval workflows that require a supervisor to authorise certain messages. Automatic conversion of multiple external recipients into blind carbon copy prevents address exposure in mass mailings, while attachment encryption and download-link delivery reduce the risk associated with sending files directly. Policy settings allow administrators to tailor rules by department, domain or content, and logs provide audit trails for compliance purposes. The product integrates at the mail gateway level and is operated in Japanese, reflecting its focus on the domestic market, where controls on erroneous transmission are a common governance requirement. Target customers include local governments, financial institutions, healthcare providers, manufacturers and other enterprises handling sensitive information. Pricing starts from around JPY 100,000 with a free trial; there is no permanently free version.
