CTI (Cyber Threat Intelligence)

What is Cyber Threat Intelligence (CTI)?

Cyber Threat Intelligence (CTI) is the discipline focused on collecting, analysing, and interpreting information about existing and emerging cyber threats. Its goal is to provide organisations with actionable intelligence that helps anticipate attacks, understand adversaries, and strengthen defensive strategies.

CTI goes beyond simple indicator gathering: it seeks to uncover the motivations, tactics, techniques, and procedures (TTPs) of threat actors, enabling security teams to prioritise risks and make informed decisions.

What types of CTI exist?

Cyber Threat Intelligence is typically organised into three levels:

• Strategic CTI: high-level intelligence for executives, focused on trends, geopolitical context, and business impact.
• Operational CTI: information about active campaigns, adversary behaviour, and attack patterns.
• Tactical CTI: technical indicators (IOCs), malware signatures, domains, hashes, and infrastructure used by attackers.

What benefits does CTI offer businesses?

CTI helps companies identify threats before they materialise, reduce exposure to attacks, and strengthen their security posture. It allows companies to:

• Prioritise vulnerabilities and critical assets.
• Detect malicious activity earlier.
• Improve SOC efficiency by providing enriched, context-aware alerts.
• Support incident response and accelerate containment.
• Enhance resilience by anticipating attacker behaviour.

How is CTI used in Telefónica Tech?

At Telefónica Tech, CTI is integrated into the Digital Operations Center (DOC) and enhances all managed cybersecurity services. It feeds SIEM, SOAR, XDR, SASE, and SOC operations with enriched context, helping analysts detect threats earlier, automate triage, and make faster and more accurate decisions.

CTI allows us to identify malicious infrastructures, analyse emerging malware, monitor dark web activity, and provide customers with proactive intelligence reports tailored to their industry and risk profile.
