Email SecuritySecurity for Mail Server
Multi-layered email security at mailbox and gateway level, one license.
Kaspersky Security for Mail Server (KSMS) is a comprehensive email security platform with multi-layered protection for every aspect of business email. Powered by machine learning and global threat intelligence, it defends against ransomware, phishing, QR-code scams, and the sharp rise in AI-driven impersonation that overwhelms built-in email defences. Three applications under one license cover on-premises, Exchange, and Microsoft 365. Faltrox deploys and operates it in front of your mail.
Overview
What Security for Mail Server is
Email is the world’s most widely used business communication tool and one of the most popular attack vectors — 81% of companies faced email attacks and 44% of corporate email traffic is spam. Threat actors adapt fast, and basic email security is no longer sufficient for either SMBs or enterprises. Kaspersky Security for Mail Server fortifies the heart of corporate communications with advanced, multi-layered protection.
It covers all email security tasks at both mailbox and gateway level through three applications under a single license: Kaspersky Secure Mail Gateway (an all-in-one SEG appliance), Kaspersky Security for Microsoft Exchange (API-integrated), and Kaspersky Security for Microsoft 365 (cloud-hosted SaaS). Combine them for full coverage or choose only what you need. Core technologies include complex anti-spam, phishing protection, sender authentication, content disarm and reconstruction, advanced sandboxing, and link scanning, with seamless integration into the wider Kaspersky portfolio. Faltrox runs it as your managed email defence.

FAQ
Common questions
01Does it work with Microsoft 365 and Exchange?
Yes — it includes an API-integrated application for Microsoft Exchange and a cloud-hosted SaaS application for Microsoft 365, alongside the all-in-one Secure Mail Gateway appliance. All three are available under a single license.
02Why add this over the built-in email protection?
Built-in defences are increasingly overwhelmed by ransomware, QR-code scams, and AI-driven impersonation. KSMS adds multi-layered ML detection, advanced sandboxing, content disarm and reconstruction, and strong sender authentication — the depth needed as attacker techniques evolve.
03Can we deploy just one part?
Yes. The three applications combine for comprehensive coverage or you can choose only what you need, and the deployment options span on-premises appliance, API integration, and cloud SaaS.
04Does it integrate with the rest of a Kaspersky stack?
It integrates seamlessly with Kaspersky Anti Targeted Attack, SIEM, and Next XDR Expert, so email detections feed cross-source correlation rather than sitting in an isolated console.
05How does Faltrox operate it?
We deploy the right combination for your mail platform, tune the anti-spam and detection policies, and act on quarantined and flagged mail — running it as a managed email security service in front of your inboxes.
