Building a Threat Intelligence Program

Every security team knows they need threat intelligence. The problem? Most organizations don't know where to start, or they invest in expensive platforms that collect dust because no one knows how to actually use the intelligence.

According to Gartner, by 2025, 80% of organizations will have some form of threat intelligence capability. But having the capability isn't the same as having an effective program. The difference between success and failure isn't budget—it's having a structured approach to collecting, analyzing, and acting on threat data.

This guide walks you through building a threat intelligence program that delivers real security value, whether you're a one-person security team or an established SOC.

What Is Threat Intelligence, Really?

Let's clear up a common misconception: threat intelligence is not just threat data.

Threat data is raw information—IP addresses, file hashes, domain names, vulnerability reports. It's noise without context.

Threat intelligence is analyzed, contextualized information that helps you make security decisions. It answers questions like:

• Which threats are targeting organizations like ours?
• How are attackers gaining initial access?
• What tactics should we prioritize defending against?
• Are we currently exposed to any known threats?

The goal of a threat intelligence program is to transform data into actionable intelligence that improves your security posture.

The Intelligence Lifecycle

Effective threat intelligence follows a structured lifecycle. Understanding this cycle is critical before you start building:

Most failed threat intelligence programs skip the first step—planning—and jump straight to buying tools. Don't make that mistake.

Step 1: Define Intelligence Requirements

Before you collect anything, you need to know what intelligence you actually need. This starts with understanding your organization's threat landscape.

Ask These Questions

• What assets are we protecting? Customer data, intellectual property, financial systems, operational technology?
• Who might target us? Opportunistic criminals, nation-state actors, competitors, hacktivists?
• What are our exposure points? Public-facing applications, remote employees, third-party vendors, cloud infrastructure?
• What compliance requirements do we have? GDPR, HIPAA, PCI DSS, SOC 2?
• What keeps leadership up at night? Ransomware, data breaches, business disruption, reputational damage?

From these answers, develop Priority Intelligence Requirements (PIRs)—specific questions your intelligence program should answer.

Example PIRs:

• "Are we mentioned on ransomware leak sites or hacker forums?"
• "Have any employee credentials appeared in recent data breaches?"
• "Which ransomware groups are actively targeting our industry?"
• "Are any of our vendors experiencing security incidents?"
• "What new vulnerabilities affect our technology stack?"

Step 2: Identify Intelligence Sources

Now that you know what intelligence you need, determine where to get it. Effective threat intelligence combines multiple source types:

Internal Sources

• Security logs: Firewall, IDS/IPS, endpoint detection, authentication logs
• Incident history: Past attacks provide insights into your specific threat landscape
• Vulnerability scans: What you're exposed to right now
• Threat hunting findings: Proactive searches for hidden threats

External Sources

• Dark web monitoring: Ransomware leak sites, hacker forums, credential marketplaces, Telegram channels
• Open-source intelligence (OSINT): Security blogs, researcher Twitter feeds, vulnerability databases
• Commercial threat feeds: Vetted indicators from security vendors
• Information sharing communities: ISACs, industry groups, government feeds (US-CERT, etc.)
• Vendor advisories: Security bulletins from your technology providers

Prioritize by Value

Not all sources provide equal value. Prioritize based on:

• Relevance: How well does this source address your PIRs?
• Timeliness: How quickly does this source provide intelligence?
• Accuracy: What's the signal-to-noise ratio?
• Cost: Financial cost plus the time required to process the intelligence

For most organizations, dark web monitoring provides excellent ROI because it directly addresses the PIR: "Are we currently targeted or compromised?"

Step 3: Build Your Technology Stack

You don't need a six-figure budget to start. Here's a practical stack that scales:

Minimum Viable Stack (Small Teams)

• Dark web monitoring service (e.g., AdverseMonitor) for external threat visibility
• Have I Been Pwned API for credential breach detection
• RSS feeds from key security blogs and vulnerability databases
• Spreadsheet or simple database for tracking threats and intelligence
• Slack/Teams channel for alert aggregation and team collaboration

Growing Program (Medium Teams)

• All of the above, plus:
• Threat intelligence platform (TIP) for centralizing and correlating intelligence
• SIEM integration to match threat intelligence against your logs
• Commercial threat feeds for broader indicator coverage
• ISAC membership for industry-specific intelligence sharing

Mature Program (Large Organizations)

• All of the above, plus:
• SOAR platform for automated threat response
• Threat hunting tools for proactive investigation
• Custom intelligence sources tailored to your organization
• Dedicated analyst team for deep threat research

The key principle: start simple, prove value, then expand. A spreadsheet tracking dark web mentions of your organization is infinitely better than an expensive TIP that nobody uses.

Step 4: Establish Analysis Processes

Raw threat data is worthless without analysis. Here's how to turn data into intelligence:

Daily Operations

• Alert triage: Review incoming alerts, eliminate false positives, prioritize real threats
• Contextualization: For each threat, answer: "Why does this matter to us? What should we do?"
• Indicator enrichment: Add context to IPs, domains, file hashes—who owns them, what's their reputation?
• Dissemination: Push actionable intelligence to the right teams (SOC, IT, leadership)

Weekly Activities

• Trend analysis: What patterns are emerging? Are certain attack types increasing?
• PIR review: Are we answering our priority intelligence questions?
• Source evaluation: Which sources are providing the most value? Which are just noise?

Monthly Activities

• Threat landscape report: Summarize key threats and trends for leadership
• Program metrics: Track alerts processed, threats mitigated, time-to-detection improvements
• PIR updates: Revise intelligence requirements based on business changes

Step 5: Operationalize Intelligence

Intelligence is only valuable if it changes behavior. Here's how to make sure your intelligence gets used:

For Security Operations (SOC)

• Push indicators of compromise (IOCs) to SIEM for automated detection
• Create detection rules based on emerging tactics and techniques
• Provide context for security alerts to speed up triage
• Support incident response with attacker TTPs and mitigation guidance

For Vulnerability Management

• Prioritize patching based on actively exploited vulnerabilities
• Alert when your specific technology stack is targeted by new exploits
• Track which vulnerabilities are being discussed in underground forums

For IT and Security Engineering

• Inform architecture decisions (e.g., "This cloud service is frequently targeted")
• Guide security control implementation and tuning
• Support red team exercises with real-world attacker tactics

For Leadership

• Provide executive briefings on emerging threats to the business
• Support strategic planning with threat landscape insights
• Demonstrate program value with concrete examples of threats detected and mitigated

Measuring Program Success

How do you know if your threat intelligence program is working? Track these metrics:

Operational Metrics

• Mean time to detection (MTTD): How quickly are threats identified?
• Alert accuracy: What percentage of alerts are true positives?
• Intelligence coverage: Are all PIRs being addressed?
• Source effectiveness: Which sources provide the most actionable intelligence?

Business Impact Metrics

• Threats prevented: How many attacks were stopped based on intelligence?
• Time saved: How much faster can teams respond with good intelligence?
• Cost avoidance: What breach costs were avoided through early detection?
• Risk reduction: How has the organization's security posture improved?

According to IBM's 2024 Cost of Data Breach Report, organizations with threat intelligence programs save an average of $1.02 million per breach through faster detection. That's the business case for your program.

Common Pitfalls to Avoid

Learn from others' mistakes:

• Tool-first thinking: Buying expensive platforms before defining requirements wastes money and creates complexity
• Intelligence hoarding: Collecting data but not sharing it with teams who can act on it
• Ignoring false positives: If you don't tune sources, teams will stop trusting your intelligence
• No feedback loop: Without measuring effectiveness, you can't improve
• Analyst burnout: Manual processing of high-volume feeds is unsustainable—automate ruthlessly
• Lack of stakeholder buy-in: If leadership doesn't see value, your program will lose funding

Starting Small vs. Starting Right

You don't need to build a mature program on day one. Here's a realistic 90-day roadmap:

Days 1-30: Foundation

• Define 3-5 Priority Intelligence Requirements
• Select 3 high-value intelligence sources (we recommend dark web monitoring as one)
• Set up alert delivery to a Slack/Teams channel
• Document a simple triage process
• Process your first real threats and share findings

Days 31-60: Operationalization

• Integrate intelligence into daily SOC workflows
• Create templates for different intelligence products (alerts, briefings, reports)
• Establish weekly intelligence review meetings
• Start tracking basic metrics (alerts processed, threats actioned)

Days 61-90: Expansion

• Add 2-3 additional intelligence sources
• Create your first monthly threat landscape report for leadership
• Document lessons learned and refine processes
• Present program wins to stakeholders
• Plan next-phase improvements (automation, additional sources, etc.)

The Bottom Line

Building a threat intelligence program isn't about having the biggest budget or the most sophisticated tools. It's about having a systematic approach to collecting the right intelligence and ensuring it gets to the right people at the right time.

Start with clear intelligence requirements, choose sources that address those requirements, establish simple processes to analyze and share intelligence, and continuously measure what's working.

According to Gartner research, organizations with mature threat intelligence capabilities report 2-3x faster incident response times and significantly lower breach costs. Those results don't come from expensive tools—they come from doing the basics well and building systematically over time.
