Despite the growth of AI, cloud platforms, and increasingly complex digital environments, one reality remains stubbornly consistent across the UK, Europe, and New Zealand.

Email is still the most common entry point for cyber attacks.

Phishing, credential harvesting, business email compromise, and malware delivery continue to rely heavily on email infrastructure. According to multiple industry studies, the majority of successful breaches still begin with some form of email-based social engineering.

What has changed is the sophistication of those attacks. AI is now enabling attackers to produce convincing phishing emails at scale, automate reconnaissance, and personalise messages in ways that were previously difficult to achieve.

For organisations, this means email security has moved far beyond spam filtering.

Why Email Security Is Becoming More Complex

Traditional email security tools were built to detect:

• Spam
• Known malware signatures
• Suspicious attachments
• Basic phishing patterns

Modern threats operate differently.

Attackers increasingly rely on:

• Credential harvesting pages
• Business email compromise (BEC)
• Domain impersonation
• AI-generated phishing messages
• Account takeover attacks

These techniques often bypass legacy filtering because they use legitimate infrastructure, compromised accounts, or carefully crafted social engineering.

As a result, effective email threat protection now requires multiple layers of defence.

The Layers of Modern Email Security

Organisations now typically deploy a combination of technologies and processes to reduce risk.

Key layers include:

• Pre-delivery email protection
  Filtering and scanning messages before they reach users.
• Post-delivery threat detection
  Monitoring inboxes for threats that bypass initial filtering.
• Identity and access protection
  Reducing the impact of credential theft through strong authentication and monitoring.
• User awareness and training
  Helping employees recognise suspicious messages.
• Incident detection and response
  Identifying compromised accounts and responding quickly.

The most resilient environments combine several of these layers rather than relying on a single product.

Technologies We Use to Protect Email Environments

At ITogether we take a vendor-agnostic approach, working with multiple technologies depending on the organisation’s architecture, risk profile, and operational requirements.

Some of the platforms we regularly deploy include solutions from:

Check Point Software Technologies: Harmony Email & Collaboration

Designed to protect cloud email platforms such as Microsoft 365 and Google Workspace, this solution focuses on advanced phishing detection, account takeover protection, and collaboration security.

Cloudflare

Cloudflare contributes to email security through domain protection, DNS security, and anti-phishing infrastructure that prevents attackers abusing domains and networks.

Fortra

Known for its expertise in threat intelligence and phishing protection, helping organisations detect malicious domains and protect against impersonation campaigns.

KnowBe4

Technology alone is not enough. Security awareness training platforms help employees recognise and report phishing attempts before damage occurs.

These technologies address different layers of the email threat landscape.

Sublime Security

A modern detection platform that uses behavioural analysis and open detection rules to identify complex phishing and social engineering attacks.

The Role of AI in Email Attacks

One of the biggest shifts in the last two years is the use of AI in cyber security attacks, particularly in phishing.

Attackers are using AI to:

• Generate highly convincing phishing messages
• Mimic writing styles and tone
• Scale social engineering campaigns rapidly
• Translate attacks into multiple languages

This means phishing attempts increasingly look authentic and targeted, making them harder for both users and traditional filters to detect.

Defensive technologies are also adopting AI to analyse behavioural signals and detect suspicious activity more quickly.

The Shared Challenge across the UK and New Zealand

Although regulatory environments differ, the email threat landscape looks remarkably similar across both regions.

Organisations in both the UK and New Zealand report:

• Increasing phishing sophistication
• More credential harvesting attacks
• Greater reliance on Microsoft 365 environments
• Growing board-level concern about business email compromise

Smaller organisations often assume advanced email attacks only target large enterprises. In reality, many attackers deliberately focus on organisations with fewer security controls.

Email Security is No Longer just a Technology Problem

Effective email security now sits at the intersection of:

• Technology
• Identity management
• User awareness
• Incident response
• Threat intelligence

The organisations seeing the best outcomes treat email security as a layered capability rather than a single tool.

The Bigger Picture

Email remains one of the most reliable attack paths for adversaries. The difference today is the scale, automation, and sophistication attackers can achieve with AI.

For organisations across the UK and New Zealand, strengthening email threat protection remains one of the most practical ways to reduce cyber risk quickly.

It is also one of the areas where a layered, well-designed approach can deliver immediate value.
