Category buying score	81	83Higher category-fit score
Rank	#3	#1
Context	Security & Privacy / Attack Surface Management (ASM) Software	Security & Privacy / Attack Surface Management (ASM) Software
Discovery and attribution accuracy	86Discovery accuracy is reinforced by combining automated evidence with human-curated entity attribution and buyer review controls, reducing false ownership while still requiring governance for disputed or shared infrastructure.	86The product combines automated discovery with human validation and evidence verification, which supports discovery accuracy, though the facts stop short of proving a specific accuracy rate or universal coverage of every asset type.
Exposure visibility	85Buyers receive continuous views of vulnerabilities, configurations, compromises, and related mitigation evidence at possible, likely, and confirmed levels, supporting outside-in exposure tracking across the discovered asset set.	88The current solution is defined as EASM and CAASM used together across external, internal, and cloud surfaces, giving buyers a single platform view of the combined attack surface rather than external-only scanning.
Risk prioritization	85Asset importance, finding severity, rating, and real-world impact are all part of the product, which supports risk ranking that can be aligned to business context and remediation order.	87Contextual severity, CVSS and EPSS context, expert prioritization, discovery chains, and validated attack-path context help teams order work by business-relevant risk while BAS remains a separate entitlement.
Remediation operations	83Assignments, remediation statuses, risk acceptance, rescans, forecasts, and progress reporting support operational follow-through, but the facts do not show built-in patching or endpoint remediation execution.	84Assignments, SLAs, retest requests, lifecycle tracking, dashboards, and reporting support operational handoff and repeat verification, provided the quoted expert coverage and workflow configuration match the buyer’s process.
Scale and data freshness	76Continuous scanning supports ongoing external visibility across complex corporate footprints, though specific refresh rates and search latency boundaries are not publicly stated.	78Weekly external discovery with continuously updated dashboards and always-on monitoring suits mid-market and enterprise monitoring cadences, yet public facts do not quantify maximum asset scale or refresh guarantees beyond that weekly external scan pattern.
Integrations and reporting	84REST API access plus Jira, ServiceNow, Splunk, Sentinel, XSOAR, Cortex, Sumo Logic, and Power BI connectors, together with executive and progress reporting, support embedding findings into existing security and leadership workflows.	81API access plus asset, identity, vulnerability, cloud, CMDB, and ticketing integrations, together with dashboards and reporting, support stack connectivity and stakeholder reporting, while connector limits, directionality, and field coverage require contract confirmation.
Support and total cost	56Total cost is driven by custom enterprise quotes based on organization size and monitored scope, with no verified public price, trial, or commitment term, and subsidiaries, integrations, support, or adjacent modules can further expand commercial outlay.	61Commercial access is custom-quoted enterprise subscription or contract with demo availability and no verified exact-product software trial, so total cost, commitment, support targets, and expert staffing levels cannot be compared until a proposal defines them.
