FEATURE: PHISHING behaviour. When implemented right, they can intercept and quarantine potentially harmful messages before they ever reach their intended targets.
Additionally, adding web content filtering to the mix ensures that even if someone accidentally clicks on a malicious link, the destination website is blocked before it can do any harm. Phishing campaigns often depend on users visiting a fake login page or downloading infected files. By cutting off access to these sites entirely, organisations can neutralise the attack at its next step.

A PHISHING MITIGATION STRATEGY IN 2025

SHOULD HAVE MULTIPLE LAYERS WITH DIVERSE SAFEGUARDS IN PLACE.

Another crucial line of defence lies in making it nearly impossible for attackers to impersonate your organisation in the first place. Phishing frequently works by spoofing a company’ s domain to make fraudulent emails appear legitimate. To counter this, organisations should rely on email authentication protocols like DMARC, DKIM and SPF. These protocols verify that an email truly originates from an authorised source, preventing malicious actors from sending emails that appear to come from within the company. When properly implemented, these measures drastically reduce the success rate of impersonationbased phishing attacks.
But even with filters, phishing emails are still bound to trickle down, and that is where the human layer comes into play.
