OSINT Intelligence Engine
Open-source intelligence, operationalized.
The internet is the largest intelligence source on the planet — and most of it is publicly accessible. intelsieve's OSINT engine turns scattered public data into structured, actionable security intelligence. Enumerate subdomains, analyze DNS history, detect leaked credentials in code repositories, and monitor your digital footprint — continuously and automatically.
Six pillars of open-source intelligence
intelsieve's OSINT engine covers the full spectrum of public intelligence gathering — from passive DNS reconnaissance to social media monitoring — all unified in a single platform.
Subdomain Enumeration
Discover every subdomain across your organization's domain portfolio using passive DNS records, certificate transparency logs, and search engine dorking. Identify forgotten staging environments, shadow IT, and misconfigured services before attackers do.
DNS History & Analysis
Map the complete DNS history of any domain — A records, MX records, NS changes, TXT entries, and more. Detect infrastructure changes, identify hosting providers, trace domain ownership transfers, and uncover relationships between seemingly unrelated assets.
Email Harvesting Detection
Identify corporate email addresses exposed across the public internet — in paste sites, breach compilations, web archives, and social platforms. Understand which employees are most targeted and where your organization's email footprint is leaking.
Code Repository Scanning
Continuously scan public code repositories on GitHub, GitLab, Bitbucket, and Pastebin for leaked secrets — API keys, database credentials, internal URLs, cloud tokens, and configuration files accidentally committed by your developers or third-party contractors.
Social Media Monitoring
Track mentions of your brand, executives, and key assets across social media platforms, forums, and community sites. Detect impersonation attempts, phishing campaigns using your brand, and early chatter about planned attacks or vulnerability disclosures targeting your organization.
Technical Database Aggregation
Aggregate intelligence from WHOIS records, BGP routing tables, SSL certificate databases, Shodan, Censys, and other technical data sources. Build a comprehensive map of your external technical footprint without manually querying dozens of disconnected tools.
How it works
From scope definition to correlated intelligence — in three steps.
Define Your Scope
Enter the domains, IP ranges, brand names, and executive identities you want to monitor. intelsieve automatically expands your scope by discovering related assets — child domains, associated IPs, linked organizations — so you never miss a blind spot.
Automated Reconnaissance
Our OSINT engine systematically queries passive DNS databases, certificate transparency logs, code repositories, social platforms, WHOIS registries, and technical databases. Every data point is normalized, deduplicated, and enriched with context — no manual effort required.
Correlated Findings
Raw OSINT data becomes actionable intelligence. Our correlation engine links OSINT discoveries with your attack surface findings and dark web exposure data, producing prioritized, contextualized reports that tell you exactly what to fix and why it matters.
What sets intelsieve apart
OSINT tools are everywhere. Here is why security teams choose intelsieve.
Integrated, Not Siloed
Most OSINT tools operate in isolation. intelsieve integrates OSINT directly with attack surface management and dark web monitoring. A subdomain discovered through OSINT is automatically cross-referenced against your ASM scan results and checked for credential exposure on the dark web — all in the same workflow.
Correlation Engine
Our ML-powered correlation engine automatically links OSINT findings to related discoveries across all intelligence pillars. A leaked API key found in a public GitHub repository gets connected to the associated subdomain from your ASM scan and any related credential dumps from the dark web — creating a single, unified incident instead of three disconnected alerts.
Continuous Monitoring
Forget one-time scans that go stale within hours. intelsieve continuously monitors your OSINT landscape with configurable scan frequencies — from daily sweeps on the Standard plan to near-real-time polling on Enterprise. New subdomains, fresh code commits, and emerging social mentions are caught as they appear.
API-First Architecture
Every OSINT capability available in the dashboard is accessible via our REST API. Trigger scans programmatically, pull findings into your SIEM or ticketing system, build custom automation workflows, or integrate with your CI/CD pipeline to catch leaked secrets before they reach production.
Built for real-world security workflows
From red team engagements to vendor assessments, intelsieve's OSINT engine adapts to how your team actually works.
Pre-Engagement Reconnaissance
Penetration testers and red teams use intelsieve's OSINT engine to build comprehensive target profiles before engagements. Enumerate subdomains, map DNS infrastructure, identify email addresses, and discover leaked credentials — all from a single platform, saving hours of manual tool-chaining.
Merger & Acquisition Due Diligence
Before acquiring a company, assess their external security posture with OSINT-driven reconnaissance. Discover unknown assets, exposed credentials, leaked source code, and infrastructure misconfigurations that could represent hidden liabilities or compliance risks in the target organization.
Brand Protection
Monitor the public internet for unauthorized use of your brand, executive impersonation, lookalike domains, and phishing infrastructure targeting your customers. intelsieve's OSINT engine detects brand abuse across social media, code repositories, domain registrations, and web content in near real-time.
Third-Party Risk Assessment
Evaluate the external security posture of vendors, partners, and suppliers using non-intrusive OSINT techniques. Assess their subdomain hygiene, DNS configuration, email exposure, and public code repositories without requiring any access to their internal systems.
Frequently asked questions
Everything you need to know about OSINT and how intelsieve helps you operationalize it.
What is OSINT and why does it matter for cybersecurity?
OSINT (Open-Source Intelligence) is the practice of collecting and analyzing publicly available information to produce actionable intelligence. In cybersecurity, OSINT is critical because it reveals what attackers can learn about your organization from public sources — exposed subdomains, leaked credentials, misconfigured DNS records, code repositories with secrets, and social media footprints. By proactively conducting OSINT on your own organization, you can identify and remediate exposures before adversaries exploit them.
How does intelsieve's OSINT engine differ from standalone tools like Maltego or Spiderfoot?
Standalone OSINT tools require manual operation, produce isolated results, and leave correlation to the analyst. intelsieve's OSINT engine runs continuously and automatically, integrates findings with attack surface management and dark web monitoring data, and uses ML-powered correlation to connect related discoveries across all intelligence pillars. This means you get contextualized, prioritized findings — not raw data dumps that require hours of manual analysis.
What data sources does the OSINT engine query?
intelsieve's OSINT engine aggregates data from passive DNS databases, certificate transparency logs, WHOIS registries, BGP routing tables, public code repositories (GitHub, GitLab, Bitbucket), paste sites, social media platforms, search engine caches, Shodan, Censys, SSL certificate databases, web archives, and more. We continuously expand our source coverage as new data providers become available.
Is OSINT collection legal?
Yes. OSINT by definition involves collecting and analyzing publicly available information. intelsieve's OSINT engine only queries public data sources and does not perform active scanning, intrusive probing, or any unauthorized access. All data collection methods comply with applicable terms of service and data protection regulations. However, organizations should always ensure their OSINT activities align with their local legal requirements and internal policies.
How often does the OSINT engine scan for new findings?
Scan frequency depends on your plan. Standard plans include daily OSINT sweeps across all configured scopes. Enterprise plans support configurable frequencies down to near-real-time monitoring with scan intervals as short as every 15 minutes for critical assets. You can also trigger on-demand scans via the dashboard or API at any time on Enterprise plans.
Can I use the OSINT engine to assess third-party vendors?
Absolutely. One of the most common use cases for intelsieve's OSINT engine is third-party risk assessment. You can add vendor domains and brand names to your monitoring scope and receive continuous intelligence about their external security posture — subdomain hygiene, DNS misconfigurations, exposed email addresses, leaked code, and more — all without requiring any access to their internal infrastructure.
