What is Email Security? Why do enterprises need advanced email security?

Email system (Mail Server / Email Server) is the core communication platform of the enterprise, where it stores and transmits:

• Thông tin tài chính

• Customer data

• Contracts, internal documents

• Approval and decision-making workflows

Although many organizations have used Microsoft 365 or Google Workspace, email threats continue to evolve. Hackers exploit:

• Trust in email communication

• Familiar domain names and brands

• Valid business process

👉 Email Security is not just spam filtering, but blocking the entire email-based attack chain, including:

• Phishing & Spear Phishing

• BEC (Business Email Compromise)

• Invoice fraud, money transfer fraud

• Phát tán malware và ransomware

• Email account takeover

Common email attack methods today

1. Business Email Compromise (BEC)

Attackers impersonate leaders, partners, or finance departments to:

• Wire transfer request

• Change payment account information

• Sending fake invoices

This is a type of attack that contains no malicious code, extremely difficult to detect with traditional rules.

2. Phishing & Spear Phishing

Email directs users to:

• Fake websites collecting login credentials

• Data theft form

• Fake cloud pages (Microsoft, Google, SharePoint…)

3. Phát tán malware & ransomware

Malware is sent via:

• Attachments

• Download link

• Legitimate email thread hijacking (email hijacking)

4. Email Account Takeover

After taking control of the mailbox, hackers continue to:

• Track communication flow

• Execute insider attacks

• Expand to other systems

Limitations of Secure Email Gateway and why Cloudflare Area 1 Email Security excels

Secure Email Gateway was initially designed to:

• Large-scale spam filtering

• Signature-based malware blocking

• Apply rules and blocklist

However, in cloud-first, remote work environments, SEG exposes many weaknesses:

❌ Unable to keep up with modern phishing

• Phishing today has small volume, specific targets

• Easily modify content to bypass rules

• No repeating attack patterns

❌ Architecture is no longer suitable

• Email no longer "passes through a fixed gateway"

• Users work everywhere, on multiple devices

❌ Complex administration, resource-intensive

• Must continuously create and edit rules

• Many false positives

• SOC overload alerts

According to Gartner®, modern email security must follow users and inboxes, not just stand in front of mail servers.
