What Are Phishing Attacks?
Phishing attacks are deceptive attempts to steal sensitive information, such as login credentials, financial data, or personal details. They often involve:
- Fraudulent emails pretending to be from trusted organisations.
- Links to fake websites that harvest user data.

How Email Filtering Tools Work
Email filtering tools analyse incoming messages and categorise them based on predefined criteria. These tools flag or block emails that exhibit suspicious characteristics, such as:
- Known phishing keywords or phrases.
- Suspicious links or attachments.

By identifying and quarantining suspicious emails, these tools reduce the likelihood of users falling victim to phishing attacks.
