Email SecurityEmail Threat Defense
AI-driven detection of BEC, ransomware, and advanced phishing for Microsoft 365.
Cisco Secure Email Threat Defense protects Microsoft 365 against the most advanced and pervasive email threats — business email compromise, ransomware, and sophisticated phishing that evade built-in defences. It uses AI and multiple detection engines to identify malicious intent, pinpoint the highest-priority threats, and speed response, backed by Cisco Talos. Faltrox deploys and operates it as managed email defence.
Overview
What Email Threat Defense is
Losses from ransomware and business email compromise are staggering and still rising, and built-in Microsoft 365 defences are increasingly outpaced by attacker techniques. Cisco Secure Email Threat Defense adds advanced threat detection specifically to Microsoft 365, catching the malicious, malware-less, and identity-deception attacks that evade native filtering.
It integrates with Microsoft 365 via API (no MX-record change) and applies AI-driven detection across multiple engines to understand the intent, risk, and context of a message — surfacing the highest-priority threats and giving searchable visibility for fast response and remediation. Backed by Cisco Talos threat intelligence and integrated with Cisco XDR, it turns email into a source of correlated detection rather than an isolated gateway. Faltrox deploys it, tunes the detection, and runs the response.

Analyse
Multiple AI-driven detection engines assess the intent, risk, and context of every message.
- 03
Prioritise
It pinpoints the highest-priority threats — BEC, ransomware, advanced phishing — cutting through noise.
- 04
Respond
Searchable visibility and remediation tools, plus Cisco XDR correlation, speed investigation and cleanup.
- 05
Operate
Faltrox tunes the detection, acts on flagged threats, and integrates email detections into the SOC it runs.

Works with
Part of the platform
Cisco products this pairs with, and the Faltrox services that operate it.
Delivery
You buy the outcome, not the console
Managed by Faltrox
Faltrox licenses, deploys, and tunes Cisco Email Threat Defense for your environment, then runs it as part of a managed service, so you get the protection without staffing another security console.
FAQ
Common questions
01We already have Microsoft 365 email protection — why add this?
Built-in defences are increasingly outpaced by BEC, ransomware, and advanced phishing. Email Threat Defense adds AI-driven, multi-engine detection focused on malicious intent — catching the malware-less identity-deception and sophisticated phishing attacks native filtering misses. It complements Microsoft 365 rather than replacing it.
02How disruptive is deployment?
Minimal — it integrates with Microsoft 365 via API with no MX-record change, so it deploys quickly without re-routing mail flow. Faltrox handles the integration and tuning.
03How does it catch BEC with no malware to detect?
BEC relies on identity deception rather than malicious files or links, so it needs intent-based detection. The AI engines assess the context, sender behaviour, and intent of a message to flag business email compromise that signature- and attachment-based filtering cannot see.
04Does it connect to the rest of our security stack?
Yes — it integrates with Cisco XDR so email detections correlate with endpoint, network, and identity telemetry, and with Secure Malware Analytics for attachment detonation. Email becomes a source of correlated detection rather than an isolated gateway.
05How does Faltrox operate it?
We deploy the API integration, tune the detection to your environment, act on flagged threats and remediation, and fold email detections into the SOC services we run — delivering managed email threat defence for Microsoft 365.
