spiderfoot

SpiderFoot is an open-source OSINT automation tool that gathers intelligence from 200+ data sources to map attack surfaces and support threat intelligence workflows. It runs on Python 3.7+ with a web UI or CLI interface and supports multiple entity types (IPs, domains, emails, usernames, etc.) with configurable modules and correlation rules.

What spiderfoot is

Python 3-based OSINT framework with 200+ modular integrations, YAML-configurable correlation engine, SQLite backend, RESTful API capabilities, and support for external tools (Nmap, DNSTwist, Whatweb). Exports to CSV/JSON/GEXF; includes TOR integration and can call third-party security tools.

Quickstart

Get the spiderfoot source

Clone the repository and explore it locally.

terminalbash
git clone https://github.com/smicallef/spiderfoot.gitcd spiderfoot# follow the project's README for install & configuration

Best use cases

Offensive Security & Penetration Testing

Red team reconnaissance, target fingerprinting, and attack surface mapping via automated enumeration of domains, subdomains, IPs, emails, and exposed services.

Defensive Intelligence & Exposure Monitoring

Organizations can monitor their own digital footprint to identify unintended information leakage, exposed buckets/services, and potential weaknesses before attackers exploit them.

Threat Intelligence & Investigation

Correlate data from 200+ sources (abuse.ch, AlienVault OTX, AbuseIPDB, HaveIBeenPwned, etc.) to rapidly build threat profiles and validate indicators of compromise.

Implementation considerations

  • Requires Python 3.7+ and pip dependencies (see requirements.txt). Plan ~30–60 min for initial setup and API key configuration for high-value modules.
  • Many modules are free but some (AbstractAPI, AbuseIPDB, BinaryEdge, etc.) require free-tier or paid API keys; audit which integrations your use case needs before deploy.
  • SQLite backend is single-machine; for distributed/scalable deployments, consider containerization (Dockerfile provided) or SpiderFoot HX cloud offering.
  • Correlation engine uses YAML rules (37 pre-defined); custom rules are readable but require understanding of the rule syntax and SpiderFoot module outputs.
  • TOR integration for dark web search increases privacy but complicates network policy; verify compliance with your organization's acceptable use policy.

When to avoid it — and what to weigh

  • Real-time, High-Volume Monitoring Required — Open-source version lacks cloud orchestration, multi-target scans, and change notifications. SpiderFoot HX (commercial) is designed for continuous monitoring; OSS is scan-based.
  • Multi-Tenancy or Collaboration at Scale — No built-in user management, role-based access control, or multi-user workspaces in the open-source edition. Self-hosted deployments require external auth layer.
  • Strict SLA & Commercial Support Requirements — Community-driven support via Discord; no guaranteed response times or SLAs. Latest stable release is v4.0 (Apr 2022); active commits continue but no formal support contract.
  • Compliance-Heavy Environments — No attestation of data residency, encryption at rest/transit guarantees, or audit logging built into OSS. Self-hosted deployments require manual hardening for compliance.

Security considerations

SpiderFoot performs reconnaissance and integrates with external APIs; ensure API keys are stored securely (env vars, secrets manager, not in code/config). TOR integration requires careful network policy review. Self-hosted deployments must apply TLS, authentication, and access controls. No security audit trail in OSS; audit logging not built-in. Data aggregation may include PII; compliance with GDPR/privacy laws is your responsibility. No security.txt or vulnerability disclosure policy listed in README; review security contacts on spiderfoot.net.

Alternatives to consider

TheHarvester

Lightweight Python OSINT tool focused on email/subdomain enumeration from public sources. Simpler, lower resource overhead; less comprehensive module coverage than SpiderFoot.

Maltego

Commercial OSINT platform with visual link analysis, larger module ecosystem, and managed cloud option. Steeper learning curve and licensing cost; stronger for complex investigations.

Shodan CLI + Custom Scripts

API-driven approach for targeted reconnaissance of exposed devices/services. Lower overhead, highly customizable; requires more development effort than a unified framework.

spiderfoot FAQ

Do I need API keys to use SpiderFoot?
No. 200+ modules include free data sources (ARIN, abuse.ch, AlienVault, etc.) that don't require keys. However, modules for SHODAN, HaveIBeenPwned, AbuseIPDB, and others require free-tier or paid API keys for full functionality. Audit your use case to prioritize which integrations matter.
Can SpiderFoot run headless / in production without a web UI?
Yes. CLI mode (`python3 sf.py -c`) supports headless scanning and scripting. For production, containerize with Docker (Dockerfile included) and script scans via CLI. No built-in REST API in OSS v4.0; web UI is primary management interface.
How is SpiderFoot different from SpiderFoot HX?
OSS is self-hosted, single-user, scan-based, CLI/web UI. HX adds cloud hosting, multi-user collaboration, continuous monitoring with change notifications, pre-installed third-party tools, Splunk/ElasticSearch feeds, and commercial support. Visit spiderfoot.net/open-source-vs-hx for full comparison.
What data storage and backup does SpiderFoot use?
SQLite backend (local file-based). Scans are stored in a single database file. No built-in replication or backup; you must handle backup/recovery via file system snapshots or database exports. Not suitable for distributed multi-node deployments without custom integration.
