IntelOwl
When a suspicious IP address, file, or link crosses an analyst's desk, checking it properly means querying a dozen different services (VirusTotal, Shodan, MISP...) one by one. IntelOwl does all those lookups at once through a single dashboard, for free.

Description
A security analyst investigating a suspicious file or IP address usually needs to check it against many different sources — is it a known malware hash on VirusTotal, does it show up in MISP's threat feeds, what does Shodan know about that IP — and doing that manually, service by service, is slow and easy to get inconsistent. IntelOwl automates the fan-out: submit one file or observable, and it queries dozens of internal and external analyzers at once, then correlates the results in one dashboard — like sending a single question to a room full of specialists instead of scheduling a dozen separate meetings.
IntelOwl is an open-source (AGPLv3) threat intelligence platform maintained by Certego, an Italian threat-intelligence firm, with support from The Honeynet Project. It provides a modular plugin framework — analyzers, connectors, pivots, visualizers, ingestors, and playbooks — covering both internal analysis tools (Yara, ClamAV, FLOSS, CAPA, PE emulation, Android and PCAP analysis) and integrations with over 50 external services including VirusTotal, Shodan, AlienVault OTX, URLscan, MISP, and OpenCTI. It ships a REST API, a full web GUI with dashboards, and official Python (pyintelowl) and Go (go-intelowl) client libraries, and is OpenSSF Best Practices certified.
💬 Our review
The short version: IntelOwl is a mature, well-regarded open-source hub for threat-intel lookups — free, backed by a real security vendor (Certego) and The Honeynet Project, and the 50+ integration list means it's likely to cover whatever intel sources your team already relies on.
The design choice to combine internal analysis tools (Yara, ClamAV, malware sandboxing utilities like CAPA) with external API integrations in one plugin framework is what sets it apart from being 'just an API aggregator' — it can do real analysis work itself, not only relay queries to third parties. OpenSSF Best Practices certification and an active GSoC-participating community are reasonable maturity signals for a security tool specifically.
The honest limits: IntelOwl orchestrates and correlates — it's not itself a threat-intel data source, so its usefulness scales with how many of those 50+ external services you actually have API access to, and some of those (VirusTotal, Shodan) have their own rate limits or paid tiers that cap what you can query for free. It also sits in a crowded, overlapping category with MISP (more focused on structured intel sharing between organizations) and Cortex/TheHive (more focused on the analyst investigation/case-management workflow) — the right pick depends on whether you want lookup automation (IntelOwl), community intel sharing (MISP), or full case management (TheHive/Cortex), and larger SOCs often end up running more than one of these together rather than picking a single winner.

Cons
N'est pas lui-même une source de renseignement — dépend des accès API (parfois limités/payants) aux services externes qu'il interroge
Chevauche des outils voisins (MISP pour le partage de renseignement, Cortex/TheHive pour la gestion de dossiers d'investigation)
Les grandes équipes SOC finissent souvent par faire tourner plusieurs de ces outils ensemble plutôt qu'un seul
