Why email is your biggest risk — and how we close it
The overwhelming majority of cyberattacks begin with an email. Phishing, business email compromise, malicious attachments and links remain the easiest way for attackers to reach your people. Advanced Email Security inspects every message across multiple layers before it is ever delivered to a mailbox.
Beyond blocking spam and known malware, our filtering detects impersonation and social-engineering techniques — the spoofed sender addresses and lookalike domains used in invoice fraud and CEO-impersonation attacks that traditional filters let through.
Protection covers Microsoft 365, Google Workspace and on-premise mail servers, and includes email continuity so your organisation can keep sending and receiving even if your primary mail platform suffers an outage.
Who it's for
Detection that goes beyond the basics
Dynamic URL & attachment scanning
Every link and attachment is analysed in real time — including sandbox detonation — so malicious payloads and credential-phishing pages are caught before a user can click through.
Outbound scanning
Outbound mail is inspected too — stopping data leakage and preventing your domain from being used to spread malware if an account is ever compromised.
Threat visibility & insights
Detailed reporting gives you full visibility into the threats targeting your organisation, so you can see exactly what is being blocked and where risk is concentrated.
Rapid incident response
If a threat slips through, post-delivery remediation lets us claw back malicious messages from every affected mailbox in one action.
