## What does Halo Security do?

Halo Security provides external cybersecurity solutions focused on attack surface management, vulnerability scanning, and penetration testing services. The company originated from ScanAlert, one of the first commercial website and web application vulnerability scanners developed in 2002, which later became the McAfee SECURE service after acquisition in 2008. The company was spun out in 2013 as PathDefender/TrustedSite before rebranding its security services as Halo Security in 2022.

The platform offers agentless vulnerability scanning and discovery solutions that help organizations gain visibility into their external attack surface. Their services include continuous monitoring of websites and applications, automated security testing that mimics attacker methods, and manual penetration testing conducted by their security team. The company tests web applications, e-commerce websites, internal and external networks, and cloud environments.

Halo Security serves thousands of organizations through direct sales and a partner network that includes service providers, resellers, and security solution providers. The platform provides API access for integration with existing security workflows and requires no agent installation for deployment. Their penetration testing services deliver customer-facing reports documenting vulnerabilities and security findings. The company operates with a fully remote workforce and maintains infrastructure across AWS and colocation facilities.
