Key features	Continuous internet-scale discovery of internet-facing assets and exposed services Discoverable-asset inventory with search, filtering, sorting, and asset-detail views Asset attribution evidence, confidence labels, and attribution tags Incident risk scoring with CVSS, EPSS, exploit, weaponization, and recency context REST APIs for assets, services, alerts, incidents, exports, tagging, and user management	Combined EASM and CAASM visibility across external, internal, and cloud attack surfaces Automated and manual discovery of domains, IP addresses, ASNs, ports, certificates, DNS records, products, cloud resources, users, applications, and devices Company relationship mapping, ownership context, tags, history, asset relationships, and deduplication Weekly external discovery scans with continuously updated dashboards and always-on monitoring Vulnerability, exposure, cloud-configuration, and security-control coverage analysis
Cons	Public sources do not disclose numeric price, network-size bands, payment timing, commitment duration, renewal terms, or implementation charges. Active Response automation is a separate add-on rather than a confirmed base Expander entitlement. Attack Surface Testing is a separate add-on rather than a confirmed base Expander entitlement.	No public exact-product price, currency, pricing metric, minimum quantity, payment timing, commitment, renewal, cancellation, or refund term is verified The current website uses Attack Surface Visibility as the commercial page label while current official material defines the underlying ASM solution as EASM plus CAASM Dark-web monitoring, domain monitoring, and AWS or Azure cloud-configuration reviews appear in the current attack-surface story, but universal inclusion in the ASM quote is not publicly established
Category buying score	81	83Higher category-fit score
Rank	#4	#1
Context	Security & Privacy / Attack Surface Management (ASM) Software	Security & Privacy / Attack Surface Management (ASM) Software
Discovery and attribution accuracy	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.	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	88The platform surfaces internet-facing assets, related exposure context, and attribution details, which gives buyers broad visibility into external attack surface conditions.	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	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.	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	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.	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	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.	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	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.	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	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.	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.
