Company profile
researched Aug 2026Alert Logic is a Houston, Texas-based security company founded in 2002 that delivers Security-as-a-Service solutions covering the application and infrastructure stack. Its offering combines security software built for as-a-service delivery with integrated 24x7 Security Operations Center services that provide monitoring, alerting and analyst guidance, plus day-to-day management of security infrastructure. Product lines have included Web Security Manager, elastic cloud security solutions, managed detection and response (MDR), extended detection and response (XDR) and managed web application firewall services.
The company's solutions are deployed across on-premises, cloud, SaaS and hybrid environments and are positioned to help customers address compliance mandates including PCI DSS, HIPAA HITECH, GDPR, Sarbanes-Oxley, SOC 2, NIST 800-171 and 800-53, ISO 27001 and COBIT. Alert Logic was built specifically for public and private cloud environments and partnered with more than half of the largest managed hosting and cloud service providers to secure their customers' environments.
Ownership has changed several times: venture investors including Access Venture Partners, Covera Ventures, Mercury Fund (DFJ Mercury), OCA Ventures, Updata Partners, Industry Ventures and DH Capital backed the company before Welsh, Carson, Anderson & Stowe took a majority interest alongside management in 2013. HelpSystems agreed to acquire Alert Logic in 2022, and the Alert Logic MDR and managed WAF services business later moved to LevelBlue through an acquisition from Fortra, with the services now delivered under LevelBlue.
Business model
Subscription-based Security-as-a-Service: security software purpose-built for as-a-service delivery on a multi-tenant SaaS platform, bundled with integrated 24x7 managed security operations center monitoring, alerting and analyst guidance.
