Halo Security Attack Surface Management
Mid-market and enterprise security teams drowning in shadow IT and unmanaged cloud assets will get the most from Halo Security Attack Surface Management because it discovers what you don't know you have, daily, without requiring agents or console access across your cloud environments. PCI compliance scanning as an Approved Scanning Vendor plus subdomain takeover detection addresses the external risks most teams simply miss until it's too late. This tool prioritizes asset discovery and continuous monitoring over vulnerability remediation, so teams expecting deep exploitation guidance or a single pane for internal infrastructure risk should look elsewhere.
Mid-market and enterprise security teams that struggle to find and validate unknown web applications before attackers do should pick Outpost24 CyberFlex; the combination of automated discovery with CREST-certified human penetration testing addresses ID.AM and ID.RA gaps that pure scanning tools leave open. The 12-month consumption model and unlimited re-testing mean you're not penalized for fixing issues quickly, which aligns with how modern dev teams actually work. Skip this if you need EASM without the PTaaS component or if your primary concern is dark web monitoring rather than active testing; Outpost24 is testing-first, not monitoring-first.
