External Attack Surface Management

Identify all domains, subdomains, IP addresses, and services tied to your organization, including shadow IT, forgotten infrastructure, and assets outside your direct control. The Deepinfo Platform draws on a continuously updated database of over 400 million domain names and approximately 2 billion subdomains, using reverse associations across Whois, DNS, IP, NS/MX, SSL, and web-graph signals to build your full inventory. Your team can also define custom rules based on patterns, registrant data, IP ranges, or naming conventions to automatically capture new assets the moment they appear.

Every asset in your inventory is scanned across multiple layers: Whois, IP Whois, DNS, SSL/TLS, HTTP headers, HTML source code, and open ports. Scans run continuously so changes and exposures are caught as they happen, not weeks later. All scan data is stored historically, giving your team the ability to compare snapshots, trace changes over time, and understand how your attack surface has evolved. Nothing is overwritten. Every data point has a timeline.

Scan data is analyzed to extract technologies, frameworks, server configurations, and software versions across your assets. From there, the Deepinfo Platform identifies security issues such as expired or weak certificates, DNS and SSL misconfigurations, insecure HTTP headers, exposed ports and services, outdated technologies, and known vulnerabilities (CVEs) with exploitability context. Issues are categorized by type and severity, so your team can see the full picture or drill into specific risk areas.

Query your entire asset inventory using over 1000 filters. Find assets hosted in a specific country, surface endpoints returning a particular HTTP status code, list assets running outdated technologies, or isolate those missing SSL certificates. Combine filters to build precise, custom views of your attack surface for investigation, reporting, or remediation planning. The search is designed for security teams that need answers fast, not generic dashboards.

Every asset receives a daily risk score ranging from 300 to 900, calculated based on vulnerability severity, exploitability, exposure level, and configuration posture. Each asset can also be assigned an importance weight reflecting its business criticality, which feeds into your organization-level score. Track score trends over time to measure whether your security posture is improving. Scores are also broken down by issue category and type, so you can identify which risk areas need the most attention.

Every detected issue comes with full context: what the problem is, why it matters, what could happen if it remains unaddressed, and exactly how to remediate it. Each finding includes verifiable evidence so your team can validate the issue independently. Issues are listed by type and category with filtering options to surface the ones affecting the most assets, the most recently appeared, or the highest severity. This is not a list of alerts. It is structured, actionable intelligence.
