Layered Defence — Layer 1 of 7

The Human Layer

Preparing and protecting the humans attackers target first.

Most successful attacks start with a person, not a machine: a convincing phishing email, an urgent request that skips procedure, a moment of misplaced trust. The Human layer addresses this directly — training staff to recognize and report attacks, and filtering the most common delivery channel for those attacks, email, before messages ever reach an inbox.

This is the outermost layer of a layered defence because it is where most attacks begin. Every phishing message recognized or filtered here is an incident no other layer has to handle.

User Awareness Training

User awareness training involves educating employees about potential cybersecurity risks, teaching them how to recognize and respond to threats.

Technology cannot catch every attack, and attackers know it — which is why so many campaigns target people instead of systems. Awareness training turns staff from the most-targeted part of the organization into an active line of defence: people who recognize a suspicious message, pause before acting on an urgent request, and know exactly how to report it.

Effective programs are ongoing, not annual. Short, regular content keeps recognition fresh as attacker techniques change, and simulated phishing exercises measure how the organization actually responds — providing a baseline, identifying who needs additional coaching, and demonstrating improvement over time.

Culture is the multiplier. A blame-free reporting process matters more than any single training module: a user who reports a click within minutes turns a potential incident into a non-event.

What to look for

Ongoing, bite-sized training

Regular short modules that track current attacker techniques, rather than a single annual session.

Simulated phishing

Safe, realistic phishing exercises that measure susceptibility and target follow-up training where it is needed.

Easy reporting

A one-click way to report suspicious messages, feeding real threats back to the security team quickly.

Measurable outcomes

Click rates, report rates, and trends over time — evidence the program is working, not just running.

Email Protection

Email protection refers to measures and tools used to safeguard emails from cyber threats such as phishing, malware, and spam.

Email remains the most common way attacks begin: phishing messages that harvest credentials, attachments and links that deliver malware, and business email compromise — convincing impersonations of executives or suppliers designed to redirect payments or data.

Modern email protection goes well beyond a spam filter. Inbound messages are analyzed before delivery: links are checked at delivery time and again at the moment they are clicked, attachments can be detonated in an isolated sandbox to observe their behaviour, and sender-authentication standards help verify that a message really comes from the domain it claims.

Because some threats only become apparent after delivery, the ability to retroactively remove a message from every inbox it reached — and to detect compromised internal accounts sending mail — matters as much as pre-delivery filtering.

What to look for

Phishing and impersonation detection

Analysis of sender, content, and context to catch credential-phishing and business email compromise, not just bulk spam.

Time-of-click link protection

Links re-checked when clicked, catching sites that turn malicious after the message was delivered.

Attachment sandboxing

Suspicious files opened in an isolated environment to observe what they actually do before reaching the user.

Sender authentication

Enforcement of standards such as SPF, DKIM, and DMARC to make domain spoofing visibly fail.

Post-delivery remediation

Messages identified as malicious after the fact can be pulled back from every mailbox automatically.

Part of a Layered Defence

No single technology can protect against every threat. The Human layer works alongside six other security layers, each creating another barrier an attacker has to defeat — and another opportunity to detect them.
