The Problem

Traditional email security
wasn't designed for today's attacks.
Most businesses rely on built-in Microsoft 365 protection and legacy secure email gateways that look for known threats using reputation, signatures and malware detection. These work — until they don't. Modern phishing attacks are designed to look authentic, bypass conventional checks, and target your employees directly.

The Threats Getting Through

Attacks that look completely legitimate.
Today's attackers exploit human trust, not technical vulnerabilities.
These are the modern threats slipping past traditional email filtering every day.
Business Email Compromise (BEC)
Attackers impersonate executives, suppliers or finance staff to request urgent payments or sensitive information — often with no link or attachment
From: ceo@company.cmo
"Can you urgently process this payment before 3PM? I'm about to board a flight."
Supplier Chain Compromise
A trusted supplier's mailbox is hijacked and used to send fraudulent invoices or payment changes — from an authentic conversation thread your team already trusts.
From: finance@yoursupplier.com
"Please note our bank details have changed for future invoices. Updated remittance attached."
Spear Phishing
Highly targeted emails crafted for a specific individual or department, using publicly available or stolen information to appear genuine.
From: events@industry-summit.org
"Following up on your recent conference attendance — your speaker slides are ready to review here."
Credential Harvesting Links
Malicious URLs (not attachments) directing users to convincing fake login pages that mimic Microsoft 365, Google Workspace or banking portals.
From: noreply@m365-secure.io
"Your password expires today. Sign in immediately to keep access to your mailbox."
Executive & Brand Impersonation
Attackers spoof internal users, lookalike domains or trusted brands like Microsoft, DocuSign or Xero to manipulate staff into taking action.
From: docusign-secure@d0cusign.net
"A document has been shared with you. Click here to review and sign."
Account Takeover (ATO)
A compromised internal mailbox is used to send phishing to colleagues, customers and suppliers — bypassing every external filter because it's coming from inside.
From: colleague@yourcompany.co.uk
"Quick favour — can you share that client list with me? My laptop is acting up and I need it for the 2pm call."

The Solution

A modern approach
to email threat detection.
Cloud Email Security continuously analyses
behaviour, language, intent and identity signals to identify suspicious emails in real time
even when they pass every traditional check.
Cloud-Native Deployment
Connects to Microsoft 365 or Google Workspace via API in minutes. No MX changes, no mail flow disruption, no hardware.
Behavioural Analysis
Learns how your people normally communicate, then flags anomalies in tone, timing, requests and identity signals.
Multi-Signal Detection
Evaluates sender history, intent, urgency cues, link destinations and impersonation patterns simultaneously — not in isolation.
Automated Response
Threats are removed from inboxes, quarantined and reported automatically. Our 24/7 UK SOC handles escalation.

Frequently asked questions

Frequently Asked Questions about Cloud Email Security

Do I still need Cloud Email Security if I use Microsoft 365 or Google Workspace?

Yes. Built-in protection is excellent at filtering spam and known malware, but most modern phishing attacks contain no malware and are designed to look authentic. CES adds a behavioural layer that catches BEC, impersonation and account takeover attacks that bypass the defaults.

‍

What is Business Email Compromise (BEC)?

BEC is a phishing attack where an attacker impersonates an executive, supplier or finance contact to trick employees into sending payments, sharing data or changing bank details. These emails often contain no links or attachments, making them invisible to traditional filters.

‍

How does CES differ from a traditional secure email gateway?

Traditional gateways rely on signatures, reputation and blocklists. CES analyses behaviour, language, intent, identity signals and communication patterns — so it can flag emails that look legitimate on the surface but show signs of social engineering or compromise.

‍

Will CES replace my existing email filtering?

No. CES is a layered addition that sits after your existing protection. You keep your current spam and malware filtering, and CES catches the sophisticated attacks that get through.

‍

How quickly can Cloud Email Security be deployed?

Most organisations are protected within a single business day. Deployment is cloud-based via API — no hardware, no MX changes, and no disruption to existing mail flow.

‍

Does CES protect against account takeover?

Yes. CES monitors identity signals and abnormal sender behaviour, so a compromised internal mailbox sending fraudulent invoices or suspicious requests is detected — even when the email comes from a legitimate account.
