Malwarebytes Inc. is an American cybersecurity company dedicated to developing software that protects computers and mobile devices from various malicious software and digital threats. Founded in 2008 by Marcin Kleczynski, who continues to serve as CEO, the company is headquartered in Santa Clara, California. Its core mission is to safeguard individuals and organizations worldwide from the evolving landscape of online threats, securing devices and digital identities.

Malwarebytes offers a comprehensive suite of cybersecurity products and services for multiple platforms, including Windows, macOS, Android, iOS, and ChromeOS. Key offerings include Malwarebytes Premium Security, Malwarebytes Privacy VPN, Malwarebytes Identity Theft Protection, Malwarebytes Personal Data Remover, and Malwarebytes Browser Guard. These solutions provide antivirus, anti-malware, VPN, scam detection, exploit mitigation, ransomware protection, and web protection. The company serves both consumer and business markets, with its business security division operating under the ThreatDown brand for managed and endpoint threat detection.

In recent years, Malwarebytes has continued to innovate and expand its offerings. In 2023, the company established ThreatDown as a distinct brand for its enterprise security products. Demonstrating a commitment to privacy, Malwarebytes acquired AzireVPN in 2024 to enhance its privacy-focused software portfolio. A notable development in early 2026 was the integration of Malwarebytes' scam detection and threat intelligence capabilities with leading AI platforms like ChatGPT and Claude, allowing users to verify suspicious links, messages, and phone numbers directly within these interfaces. The company also launched a Student Protection Program in the U.S. in January 2026, providing cybersecurity subscriptions to university students, faculty, and staff.
