Halo Security
What Halo Security is
Halo Security is an external attack surface management platform for finding and monitoring internet-facing assets. It discovers and catalogs known and unknown domains, hostnames and IP addresses, with daily updates. Agentless scanning checks internet-facing assets for vulnerabilities, including issues beyond known CVEs such as subdomain takeovers and misconfigured cloud services. The platform tracks risk scores, applies severity ratings and the Known Exploited Vulnerability catalog to help prioritize issues, and provides remediation guidance. Optional cloud connectors include AWS, GCP, Azure and Cloudflare. Listed integrations also cover tools such as Jira, PagerDuty, Vanta, Splunk, Slack, Google Chat and ServiceNow. Access is available through web and API. External asset discovery is included, but scanning is limited to the target quantity in a subscription. The free trial requires no credit card and includes discovery plus firewall, website and technology scanning for up to 100 targets. Halo identifies itself as a PCI DSS Approved Scanning Vendor. It offers support-team onboarding, and says most customers are fully onboarded within 3–7 days. Pricing starts at $399 a month; there is no free plan.
