The #1 Threat Vector

Why Email Security Is Critical

Over 90% of cyberattacks begin with a malicious email. From sophisticated spear-phishing targeting your executives to automated malware campaigns sweeping thousands of inboxes — email is the most exploited attack surface in any organisation.

CommuniCloud's email security solution goes far beyond basic spam filtering. We deploy multi-layered AI-powered defences that analyse sender behaviour, content patterns, and link destinations in real time — stopping threats that bypass traditional gateways.

What We Stop

  • Phishing & Spear-Phishing

    AI-powered detection of targeted phishing campaigns including zero-day attacks invisible to signature-based tools.

  • Business Email Compromise (BEC)

    Stop impersonation attacks that redirect payments or harvest credentials by mimicking trusted senders.

  • Ransomware & Malware

    Sandbox analysis of attachments and links before delivery eliminates ransomware delivery via email.

  • Domain Spoofing

    DMARC, DKIM, and SPF enforcement prevent attackers from impersonating your domain to target partners and clients.

Threats We Neutralise

Email Threat Landscape

Phishing

Credential-harvesting emails disguised as trusted services. Our AI analyses thousands of signals to catch even the most convincing fakes.

BEC & CEO Fraud

Impersonation of executives or suppliers to authorise fraudulent transfers. Identity-based controls stop these cold.

Ransomware Delivery

Malicious attachments and links that deploy ransomware. Sandboxed detonation of every attachment before delivery.

Zero-Day Threats

Novel attack techniques with no existing signatures. Behavioural AI detects anomalies rather than relying on known patterns.

Account Takeover

Compromised email credentials used to launch internal attacks. Anomalous login detection and MFA enforcement.

Data Exfiltration

Sensitive data leaving the organisation via email. DLP integration flags and blocks outbound policy violations.

Common Questions

Email Security FAQ

Does email security work with Microsoft 365 and Google Workspace?

Yes. CommuniCloud's email security integrates natively with both Microsoft 365 and Google Workspace via API, providing in-line scanning without changing your MX records. We enhance Microsoft Defender and Google's built-in protections rather than replacing them.

How quickly can email security be deployed?

Most organisations are fully protected within 24–48 hours. Our team handles the entire setup including SPF, DKIM, and DMARC configuration to protect your domain from spoofing.

Will it affect legitimate email delivery?

Our false-positive rate is extremely low. We use multiple signals to assess emails, and borderline cases are quarantined for user review rather than hard-blocked. Most users notice only an improvement in inbox quality.

What happens when a threat is detected?

Threats are quarantined automatically and an alert is sent to your security administrator. Depending on severity, our SOC team may initiate an incident response workflow within minutes. You receive a detailed report of all blocked threats.

Can you protect against insider threats via email?

Yes. Our DLP integration monitors outbound email for sensitive data — financial records, IP, customer data — and blocks or flags policy violations. Behavioural baselines detect unusual sending patterns indicative of malicious insiders.

Do you offer email security training for staff?

We provide phishing simulation campaigns and security awareness training as part of our managed email security service, helping your team recognise and report threats as a second line of defence.

Is your email security compliant with Australian privacy laws?

Yes. All email data processing occurs within Australian data centres, ensuring compliance with the Australian Privacy Act 1988 and associated regulations. We can provide a data residency confirmation for compliance purposes.

How does your service compare to basic Microsoft Defender?

Microsoft Defender provides foundational protection. CommuniCloud layers advanced sandboxing, behavioural AI, threat intelligence from our CREST-certified SOC, and 24/7 human analyst oversight on top — catching sophisticated targeted attacks that automated tools miss.
