Cyber Threat Intelligence (CTI) is the collection, analysis, and processing of data to understand potential threats, attack behaviours, and the motivations of cybercriminals. By gaining insights into cyber threats, security teams can shift from reactive to proactive approaches, enabling better preparedness against potential breaches.

Gartner defines CTI as evidence-based knowledge about existing or emerging threats, including actionable advice on preventing or addressing those threats. This information helps organizations understand not just the type of cyber threats they face but also the motives, tactics, and behaviours of attackers.
Why is Cyber Threat Intelligence Important?
In the constantly evolving landscape of cybersecurity, advanced persistent threats (APTs) continually adapt their methods, making it essential for defenders to stay one step ahead. Understanding an attacker’s next move allows organizations to strengthen defences.
Many organizations recognize the importance of threat intelligence but may not fully utilize it. Advanced threat intelligence goes beyond simply identifying threats; it provides context about attackers’ tactics and motivations, allowing businesses to tailor their defences more effectively.
CTI offers several key advantages:
It sheds light on previously unknown threats, enabling better security decisions.
It reveals an attacker’s motives, tactics, techniques, and procedures (TTPs).
It empowers security professionals to understand the decision-making processes of cybercriminals.
It helps executives and security leaders allocate resources more effectively, reduce risks, and make faster decisions.
Who Benefits from Cyber Threat Intelligence?
CTI is beneficial for organizations of all sizes, from small businesses to large enterprises. Smaller companies may not have the resources for extensive in-house security teams, but threat intelligence helps them achieve a level of protection that would otherwise be out of reach.
Each member of a security team benefits from CTI in different ways:
Security Analysts can optimize detection capabilities and improve overall defence strategies.
Security Operations Centres (SOC) can prioritize incidents based on the risk and impact to the organization.
Incident Response Teams (CSIRT) can accelerate investigations and resolve incidents more effectively.
Intel Analysts can track threat actors and uncover ongoing threats to the organization.
Executive Management can better understand the risks the organization faces and make strategic decisions.
The Cyber Threat Intelligence Lifecycle
CTI follows a structured process known as the intelligence lifecycle, which helps convert raw data into actionable intelligence. This cycle consists of six key steps:
Requirements: Security teams define objectives, such as understanding attacker motives or identifying vulnerabilities.
Collection: The team gathers relevant data from sources like logs, social media, and public databases.
Processing: Raw data is cleaned, organized, and prepared for analysis.
Analysis: Analysts interpret the processed data to extract actionable insights, identifying threats, vulnerabilities, and recommended actions.
Dissemination: The results are presented in a concise format, such as a report or presentation, tailored to the needs of stakeholders.
Feedback: Stakeholders provide feedback on the intelligence gathered, which helps refine future intelligence operations.
By following this lifecycle, organizations can continuously improve their ability to identify and respond to emerging cyber threats, ensuring stronger security postures in the face of evolving dangers.
