About
Cofense is a cybersecurity company headquartered in Leesburg, Virginia that provides phishing defense solutions built around the insight that employees who have been trained to recognize and report phishing emails become a real-time human sensor network capable of detecting attacks that email gateway security controls miss. The company's platform has two complementary components: PhishMe, a phishing simulation and conditioning program that trains employees to recognize phishing techniques and builds the reporting behavior habit, and Triage, an automated phishing email analysis and response platform that processes the reports employees generate and orchestrates quarantine of confirmed malicious emails across the organization.
