Lookout

Lookout is an enterprise cybersecurity company focused on mobile AI security, mobile threat defense and mobile endpoint detection and response. Its products protect commercial Android and iOS devices, helping organizations identify threats, investigate mobile risk and enforce security policies. Founded in 2007 as Flexilis, Inc., the company developed from an early smartphone security business into a provider focused on enterprise mobile protection.

The Lookout Mobile AI Security Platform brings together threat detection, exposure management and automated remediation. Its capabilities address mobile phishing, SMS phishing, social engineering and executive impersonation, alongside malicious applications and vulnerabilities in mobile software. Mobile endpoint intelligence can be integrated with enterprise SIEM, SOAR, EDR and XDR systems, allowing mobile signals to inform broader security monitoring and response. Risk-based conditional access supports decisions about whether devices should access organizational resources.

Mobile security and emerging AI risks

Lookout's more recent platform development addresses the security implications of mobile AI adoption. Introduced during 2025 and 2026, AI Visibility & Governance capabilities help organizations discover unapproved mobile AI tools and manage Shadow AI exposure. The Mobile Software Exposure Center extends its work into mobile software supply-chain risk, examining vulnerabilities and application exposure. Application vetting and threat intelligence complement these capabilities.

The company serves public-sector and commercial organizations, including federal, state and local government agencies, financial services, healthcare, manufacturing, retail and telecommunications. Its research function, Lookout Threat Lab, investigates mobile malware, surveillance software and exploit campaigns to support understanding of threats affecting mobile devices.

Business evolution

Lookout narrowed its portfolio through two divestitures: its consumer mobile security business went to F-Secure in June 2023, and the sale of its Cloud Security business to Fortra was announced in May 2025. The latter covered cloud security technologies including CASB and ZTNA. These changes underpin its current emphasis on enterprise mobile risk. The company subsequently established its global corporate headquarters in Boston while retaining an international network of engineering and regional operations.
