How threat intelligence works
Intelligence comes from open sources, commercial feeds, government and sector sharing groups, and the organization's own incident data. Analysts collect, correlate and assess this data for relevance and reliability.
It is used at several levels: tactical indicators such as malicious IP addresses, operational insight into campaigns, and strategic reporting for leaders. Findings feed SIEM rules, blocklists, hunting and vulnerability prioritization. Context is what separates useful intelligence from noise, so analysts rate sources for reliability, record confidence levels and ask whether a given report is relevant to their sector, region and technology.
Why it matters for Canadian organizations
Security teams face more alerts and vulnerabilities than they can handle. Intelligence helps them focus on threats that actually target their sector and technologies rather than treating every warning equally.
The Canadian Centre for Cyber Security publishes alerts and advisories, and sector information-sharing groups exist for areas such as finance and energy. Sharing and consuming this information helps Canadian organizations spot campaigns that affect their peers. Smaller organizations may not need a dedicated feed, but they benefit when their security provider turns external reporting into detections, blocks and prioritized patching on their behalf.
How to implement it
Define what decisions you want intelligence to support, such as patching priorities or detection tuning. Choose a small number of high-quality sources and integrate them into your SIEM and ticketing tools.
Use a sharing standard such as the Traffic Light Protocol to handle sensitive reports correctly, remove stale indicators, and measure whether intelligence changes outcomes. A managed SOC can supply and apply intelligence if you lack analysts. Avoid collecting more indicators than you can act on, and retire expired ones, because stale data produces false alerts and can block legitimate services.
Frequently asked questions
What are the types of threat intelligence?
The common types are strategic, for executive decisions; operational, about attacker campaigns and intent; tactical, covering techniques and procedures; and technical, which are indicators such as IP addresses, domains and file hashes. Quality matters more than the quantity of sources used.
Is threat intelligence the same as threat hunting?
No. Threat intelligence is information about threats, while threat hunting is the proactive search for attackers inside your environment. Hunters often use intelligence to decide what behaviors or indicators to look for. Both practices complement each other well in a mature program.
Do small organizations need threat intelligence?
They benefit from it, but usually through free government advisories and the intelligence built into their security vendors or managed service provider. Building a dedicated intelligence team is rarely practical for smaller organizations. Free government sources are a practical starting point for many teams.
