Threat Intelligence: A Practical Guide to the Sources, Strengths, and Shortcomings

Published by Marshal on

To effectively protect people, assets, operations, and data, organizations rely on threat intelligence from a range of sources. That intelligence can point to a ransomware campaign targeting remote workers, a spike in thefts along a logistics corridor, or a protest planned near a regional HQ. It can come from internal sensors, government alerts, or shared industry intel. Here’s a breakdown:

1. Commercial Intelligence Providers

Companies subscribe to specialist firms for access to threat feeds, risk alerts, and deep-dive analysis across digital and physical domains.

Examples:

  • Detection of phishing kits, malware variants, or zero-days

  • Geopolitical risk reports, protest forecasts, crime trends

Pros:

  • High-quality, curated, often global in scope

  • Sector-specific and often tailored by location or threat profile

  • Regular updates, sometimes in real-time

Cons:

  • Cost can be significant

  • May overwhelm without internal capability to filter and act

  • Can create dependency on a single vendor’s lens

2. Government and Law Enforcement Agencies

Agencies like CISA, NCSC, FBI, and OSINT-focused branches of law enforcement provide situational alerts, bulletins, and trend analysis.

Examples:

  • Cybersecurity advisories on CVEs or TTPs used in active campaigns

  • Warnings of regional unrest, terror alerts, or transnational crime threats

Pros:

  • Vetted and grounded in real incidents

  • Usually free and accessible

  • Broad in scope with strategic context

Cons:

  • Often slow to release information during live incidents

  • Too generalized to support tactical decisions

  • Regional or national blind spots depending on jurisdiction

3. Open-Source Intelligence (OSINT)

Organizations collect intelligence from publicly available data, including social media, blogs, vulnerability databases, traffic apps, news outlets, and video feeds.

Examples:

  • Hacker forums discussing exploits or breaches

  • Live reports of strikes, blockades, or suspicious activity near facilities

Pros:

  • Free and fast

  • Great for early situational awareness

  • Can cover obscure or emerging sources

Cons:

  • Requires validation—easily polluted with disinfo or rumors

  • Time-consuming without automation or trained analysts

  • High noise-to-signal ratio

4. Industry Intelligence-Sharing Networks

Sector-specific organizations like ISACs (Information Sharing and Analysis Centers) and OSAC (for overseas physical security) enable peer-to-peer exchange of threats, tactics, and incidents.

Examples:

  • A shipping company shares IOCs from a recent cyber intrusion

  • A multinational shares a risk update about regional gang activity

Pros:

  • Highly relevant—peers face similar threats

  • Builds trust and improves response coordination

  • Sometimes enables anonymized, candid sharing

Cons:

  • Depends heavily on member participation

  • Updates may lag behind fast-moving incidents

  • Access can be restricted by industry or membership requirements

5. Internal Monitoring and Incident Data

Threat intelligence isn’t always external. Most companies generate a constant stream from internal systems and teams.

Examples:

  • Security logs from SIEM, IDS, EDR tools

  • Physical incident reports, access control anomalies, or guard shift logs

Pros:

  • Directly tied to your environment and operations

  • Enables rapid triage and response

  • Provides pattern recognition over time

Cons:

  • Offers no insight into external or emerging threats

  • Requires mature tools, people, and processes

  • Often siloed (cyber vs. physical teams) unless integrated

6. Security Vendors and Technology Partners

Cybersecurity tools, access control systems, video surveillance platforms, and building automation vendors often supply threat updates based on their customer base and telemetry.

Examples:

  • Firewall vendor pushing threat signatures

  • Video analytics detecting loitering or unusual behavior

Pros:

  • Often real-time, with auto-response capability

  • Built into systems already in use

  • Useful for day-to-day operational security

Cons:

  • Narrow scope—only sees what that vendor sees

  • May not disclose full methodology behind alerts

  • Easy to overlook strategic threats without broader sources

7. Dark Web and Underground Monitoring

Monitoring criminal forums, darknet marketplaces, and Telegram channels can reveal intent, capabilities, and targeting across both cyber and physical domains.

Examples:

  • Breach data sales, insider recruitment posts

  • Coordination of physical attacks or smuggling operations

Pros:

  • Early visibility into planned attacks or leaks

  • Valuable for brand protection, fraud prevention, and insider risk

  • Often includes direct mentions of company or region

Cons:

  • Requires specialist tooling and expertise

  • Legal and ethical risks if handled carelessly

  • Difficult to operationalize without context

 

Every source of threat intelligence has value—but also limitations. The strongest programs integrate across sources, enrich with context, and break down the wall between physical and cyber security teams. The goal isn’t just knowing what threats exist—it’s knowing what to do about them, before they disrupt your people, operations, or brand.
