ThreatDown is an American business-to-business cybersecurity company headquartered in Santa Clara, California. The company originated from Malwarebytes, a well-known cybersecurity company recognized for its contributions to modern threat remediation. ThreatDown provides managed security services, such as Managed Detection and Response (MDR) and cybersecurity solutions, such as Endpoint Detection and Response (EDR) and Email Security, for businesses of all sizes.

History

The birth of Malwarebytes

Malwarebytes was founded in 2008 by Marcin Kleczynski, who developed the first prototype of its malware remediation software at the age of 14. The idea originated from a personal experience in which Kleczynski inadvertently infected his family computer with malware. Frustrated by the limitations of existing solutions, he collaborated with online communities and eventually created a tool to address the issue, which he began distributing for free.

Malwarebytes grew rapidly, achieving millions of dollars in sales by the time Kleczynski was 18. Over the next two decades, the company evolved into a global cybersecurity provider, offering a suite of products to protect both consumers and businesses.

The launch of ThreatDown

The Malwarebytes for Business product portfolio expanded in April 2018 with the introduction of its Endpoint Detection and Response (EDR) solution, followed by the launch of Managed Detection and Response (MDR) in October 2022. These offerings marked the company’s move toward comprehensive enterprise security services.

In November 2023, Malwarebytes introduced ThreatDown, a dedicated business unit and brand for its business-focused cybersecurity solutions. Formerly known as Malwarebytes for Business, the ThreatDown mission focused on simplifying security for resource-constrained IT teams by combining advanced threat detection and remediation with ease of deployment and management.

In 2025, ThreatDown expanded its portfolio to include email security capabilities, aiming to provide broader protection against phishing and other email-based threats.
