Research explores many signals

Phishing detection research often studies URL features, page content, sender context, screenshots, text, and behavior. These approaches can help classify and prioritize suspicious links.

Machine learning needs careful data

Models depend on training data, labels, evaluation methods, and changing attacker behavior. A model that works in one dataset may not generalize perfectly to new campaigns.

Transformers can help with language and context

Modern models can summarize messages, compare text patterns, and assist review. They still need guardrails, explanations, and human oversight.

Practical limits remain

Attackers adapt. New pages appear quickly. Legitimate links can look strange. False positives and false negatives are unavoidable risk-management problems.

What CheckLink claims today

CheckLink currently emphasizes explainable URL/domain signals and manual review. ML-assisted review is a planned signal, not a current guarantee.

FAQ

Does AI guarantee phishing detection?

No. AI can support detection and triage, but it cannot guarantee every phishing link is caught.

Does CheckLink claim production ML detection?

No. Current CheckLink positioning is based on available signals and manual review paths.
