FullHunt vs Qualys External Attack Surface Management

FullHunt provides internet intelligence for security products and external attack surface monitoring, through web access, APIs, data feeds, and MCP. It discovers internet-facing domains, subdomains, IPs, cloud services, ports, technologies, and certificates. Continuous monitoring follows new assets, service and certificate changes, configuration drift, and exposure alerts. Its vulnerability intelligence links CVEs to observed assets with exploit context, EPSS scores, and CISA KEV status. Enterprise workflows also cover compromised credentials, infostealer activity, typosquatting, and phishing infrastructure tied to monitored organizations. Listed integrations include security platforms, ticketing systems, and collaboration tools such as Splunk, Jira, Slack, and Microsoft Teams. Developers can use REST APIs, a Python SDK, and MCP tools; API requests use credits that reset monthly. Plans range from a free option with 10 credits per month to paid plans from $149 a month. A 14-day trial is listed for qualified Enterprise organizations. Users must have lawful authority to monitor submitted assets and use the service for legitimate cybersecurity purposes.

Qualys External Attack Surface Management gives security teams an outside-in view of internet-facing infrastructure and continuously monitors connected assets. It discovers domains, subdomains, cloud workloads, web applications, APIs, certificates, and exposed services, then identifies organizational ownership and maps asset relationships. The service can flag unapproved cloud services, test environments, abandoned assets, and other unmanaged resources, as well as changes to existing services and newly exposed assets. Qualys TruRisk scores prioritize discovered assets using vulnerabilities, misconfigurations, asset criticality, and external exposure. Assets can be added to inventory and scanned with VMDR. Listed native integrations include Certificate View, Policy Compliance, and Web Application Scanning. CSAM with EASM can produce PCI-DSS and FedRAMP asset security health reports and offers bidirectional ServiceNow CMDB integration. The managed service is accessed through a browser and needs no local server or software installation. A no-cost CSAM with EASM offer is listed at free for 30 days; other pricing is on request. Shodan-based discovery on leased IPv4 netblocks requires contacting a Qualys Technical Account Manager.
