What Halo Security is
Halo Security is an external attack surface management platform available through web access and an API. It discovers and catalogs known and unknown internet-facing domains, hostnames and IP addresses, updating the inventory daily. Agentless scanning covers internet-facing assets and can identify issues beyond known CVEs, including subdomain takeovers and misconfigured cloud services. Risk scores, severity ratings and the Known Exploited Vulnerability catalog help prioritize findings, with remediation guidance for follow-up. Optional cloud connectors support AWS, GCP, Azure and Cloudflare, while listed integrations include Jira, PagerDuty, Vanta, Splunk, Slack, Google Chat, ServiceNow, GoDaddy, Linode, F5 BIG-IP and Zapier. External asset discovery is included, but security-scanning quantities depend on the subscription. A trial requires no credit card and covers discovery plus firewall, website and technology scans for up to 100 targets. Halo identifies itself as a PCI DSS Approved Scanning Vendor.
