About Cofense

Cofense sells a phishing defense platform that identifies and removes phishing campaigns reaching employee inboxes, along with phishing training built from real attack data. Cofense says it is the only cybersecurity platform focused exclusively on stopping phishing. Cofense says it is purpose-built for phishing, the most persistent and costly cyber threat.[2][6][7]

Cofense says its expert-supervised AI, combined with real-time intelligence from 35M+ trained users, detects advanced phishing attacks other solutions miss and remediates them in minutes. Cofense says its phishing-specific AI is continuously trained and validated by human analysts.[2][7]

The problem Cofense says it addresses starts after delivery. Cofense says polymorphic campaigns slip past secure email gateways and AI-only defenses. Cofense says removing one email at a time leaves entire campaigns active in inboxes. Cofense combines purpose-built phishing AI, trained on real attacks, with expert validation for post-perimeter detection. Cofense says it augments existing email defenses, covering phishing detection and response gaps.[6][7]

The Cofense Phishing Defense Platform is powered by phishing-specific AI trained on billions of data points and signals from millions of reporters. Cofense says threat intelligence from real attacks connects remediation and training into a single defense rather than separate tools. Cofense says its phishing-specific AI classifies and processes reported threats at scale, and every decision it makes is explainable and analyst-verified. Cofense Command Center is one place to run a phishing defense program and prove it is working. Cofense says Phishing Remediation data in Cofense Command Center adds real-world threat and remediation context alongside training and competency insights.[2][8]

Cofense says Cofense Phishing Remediation goes further than detecting threats that evade perimeter defenses, and that Cofense removes threats with 99.998% accuracy. Cofense says it can remove confirmed threats in seconds and automatically eliminate similar threats going forward. Cofense says it quarantines every variant of a confirmed campaign in under a minute. Cofense describes AI-powered clustering to detect polymorphic attacks before threats are confirmed. Cofense also describes email triage and response with precision clustering, AI-driven auto classification, and click tracking to process reported threats in minutes.[2][8]

Cofense Phishing Training uses real phishing data for adaptive simulations and awareness programs. Cofense says its training turns verified attacks into real-world simulations instead of generic templates. Cofense says simulations can replicate smishing, vishing, and QR-code phishing. Cofense says employees can report threats with one click into a global intelligence network. Cofense says it turns real attacks into the simulations employees train on, then measures competency against what attackers are actually sending.[2][3]

Cofense says its experts can manage detection, remediation, and training end to end, taking the operational load off the customer's team. Cofense connects to the tools customers already use, and says intelligence and remediation extend across the existing stack.[2][3][6][8]
