  • Transform threat intelligence into actionable insights with contextualized data that aligns with your organization’s unique cybersecurity challenges.
  • Strengthen your cybersecurity posture by mapping your attack surface, prioritizing threats, and focusing on what matters most to your business.
  • Partner with Trustwave for advanced threat intelligence services that deliver timely, relevant, and risk-based protection tailored to your environment.

Security teams receive thousands of threat indicators daily. IP addresses, domain names, file hashes, and vulnerability advisories flood their inbox from multiple intelligence feeds. Yet when the next breach happens, you're still caught off guard. Sound familiar?

The problem isn't a lack of information; it's a lack of context. Generic threat intelligence treats all organizations the same, regardless of whether they are in Australia, the US, or the UK, but your attack surface, business model, and risk profile are unique. Without understanding what matters specifically to your organization, threat intelligence becomes expensive noise.

Know Your Attack Surface Before You Know Your Threats

Before subscribing to another threat feed, ask yourself: what are you trying to protect, and how could it be attacked?

Map Your Digital Footprint

Start with an asset discovery phase that goes beyond your network inventory. Your attack surface includes cloud infrastructure, remote workers, third-party integrations, and even your organization's public presence on social media, along with your physical facilities. Attackers don't respect organizational boundaries; they exploit whatever path offers the least resistance.

Consider a healthcare organization: its attack surface includes not just medical devices and patient databases, but also HVAC systems, parking payment kiosks, and the personal devices of doctors accessing patient records from home. Each represents a potential entry point that requires different defensive strategies.

Understand Your Business Logic

Threat intelligence becomes actionable when you understand how your business actually operates. What systems would cause the most damage if compromised? Which data flows are critical to operations? Where are your single points of failure?

For example, a logistics company might be most vulnerable to attacks targeting its route optimization systems, while a financial services firm needs to prioritize threats to its trading platforms. Generic malware signatures matter less than understanding who would want to target your specific business processes and why.

The Context Problem: Why Generic Intelligence Fails

Most threat intelligence suffers from what security professionals call "the list of badness" problem. You receive feeds containing millions of indicators with little information about their relevance to your environment.

The Attribution Gap

You get an alert about a new malware family, but you don't know if it targets your industry, your geography, or your technology stack. Without attribution and context, you can't prioritize response efforts effectively. Your team ends up chasing every threat equally, which effectively means they're chasing none of them well.

The Timing Trap

Threat intelligence often arrives too late to be preventive and too early to be clearly relevant. By the time you receive indicators about a specific campaign, the attackers may have already moved on to new infrastructure. Conversely, early warnings about emerging threats may not include enough detail to take meaningful action.

The Relevance Problem

Intelligence feeds frequently lack the granular context needed for operational decision-making. Knowing that a particular threat actor targets healthcare organizations is useful, but knowing that they specifically exploit unpatched medical device vulnerabilities through spear-phishing campaigns targeting IT administrators is actionable.

Building Intelligence That Actually Protects

Effective threat intelligence starts with clearly defined intelligence requirements based on your organization's specific risk profile.

Define Your Intelligence Requirements

Rather than consuming everything available, identify what you specifically need to know. This might include threats targeting your specific industry, attacks exploiting technologies in your environment, or campaigns originating from regions where you operate.

For a retail organization, priority intelligence might focus on point-of-sale malware, e-commerce fraud techniques, and supply chain attacks. For a defence contractor, the focus would shift to advanced persistent threats, intellectual property theft, and nation-state activities.

Implement Contextual Enrichment

Raw indicators become valuable when enriched with organizational context. This means correlating external intelligence with your asset inventory, vulnerability assessments, and business processes. An IP address blocked by your firewall becomes more significant when you discover it's associated with attacks targeting your specific industry.

Prioritize Based on Business Impact

Not all threats deserve equal attention. Develop a framework for prioritizing intelligence based on the potential business impact of successful attacks. This requires understanding your organization's crown jewels and the attack paths that could lead to their compromise.

5 Practical Steps to Improve Your Intelligence Program

  1. Start with Internal Intelligence - Before looking outward, understand what your environment is telling you. Security logs, incident reports, and vulnerability scans provide intelligence about threats that have already targeted your organization. This internal intelligence often proves more valuable than external feeds because it's automatically relevant to your environment.
  2. Collaborate Within Your Industry - Industry-specific threat-sharing organizations often provide more relevant intelligence than generic commercial feeds. These communities understand your business model and can provide context that generic vendors cannot match.
  3. Measure Intelligence Effectiveness - Track how often your threat intelligence leads to actionable defensive measures. Are you blocking attacks based on intelligence? Are you prioritizing patches based on threat actor targeting? If your intelligence isn't changing your defensive posture, it's not working.
  4. Invest in Analysis, Not Just Data - The most expensive part of threat intelligence isn't the data—it's the analysis required to make it actionable. Invest in training your team to understand attack patterns, business context, and the connection between the two. Next, leverage a trusted security partner to supplement and share what they are seeing across your industry and with your context.
  5. The Future of Contextual Intelligence - The organizations that will thrive in the current threat landscape are those that move beyond generic threat consumption to contextual intelligence programs. This means understanding not just what threats exist, but which ones matter to your specific organization and why.

Effective threat intelligence doesn't just inform you about attacks, it helps you understand your organization through an attacker's eyes. When you achieve this perspective, you can finally move from reactive security to proactive defence.

For example, in Australia and New Zealand, that often means measuring against frameworks like the ASD Essential Eight, ensuring compliance with APRA CPS 234, or understanding how IRAP-assessed environments are targeted.

Your attack surface is unique. Your threats should be too.

Ready to transform your threat intelligence program? Start by conducting a comprehensive attack surface assessment and mapping your organization's unique risk profile. The threats that matter most to your organization are the ones that understand your business as well as you do.

Trustwave's Threat Intelligence-as-a-Service can provide you with timely, contextualized, and prioritized threat intelligence based on factors relevant to your operations and your exposed attack surface, enabling you to make risk-based and threat-informed decisions that benefit your organization.
