Category buying score	81Joint highest score	81Joint highest score
Rank	#3	#4
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.	89The product is documented to continuously discover and index unknown risks and to provide a comprehensive inventory, but the facts do not quantify discovery coverage by asset class, so the score stays below maximum.
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 platform surfaces internet-facing assets, related exposure context, and attribution details, which gives buyers broad visibility into external attack surface conditions.
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.	89Incident risk scores factor CVSS, EPSS, weaponization, exploitation in the wild, and exploit recency, and support custom rules or manual assignment, enabling prioritization of external findings by exploitability and threat context.
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.	63The product can route exposures into IT tickets and workflows, but automated remediation is not part of confirmed base Expander and is instead associated with the separate Active Response module.
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.	86The SaaS platform continuously scans the internet and operates without agents or internal infrastructure, which supports broad external coverage and current data collection, but the facts do not quantify refresh intervals or scale thresholds.
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.	82REST APIs cover assets, services, alerts, incidents, exports, tagging, and user management, and outbound integrations push or pull data into third-party security or workflow tools, enabling reporting and handoff into existing operations stacks.
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.	51The product has no public numeric price, network-size thresholds, payment timing, or implementation charges, and it requires a base-platform SKU plus a network-size SKU with separate add-ons for some functions, which leaves total cost and entitlement clarity dependent on the quote.
