Sentar is seeking a Cyber Threat Intelligence (CTI) Analyst!

Role Description:

The Cyber Threat Intelligence Analyst evaluates adversaries, campaigns, vulnerabilities, and emerging threats relevant to the customer mission and operating environment. The analyst integrates external intelligence with internal security telemetry to explain what is happening, assess potential impact, identify intelligence gaps, and recommend practical defensive actions.

The analyst delivers tactical, operational, and strategic intelligence to Security Monitoring, Security Operations Center, threat hunting, incident response, detection engineering, purple team, and leadership stakeholders. Products must distinguish verified observations from analytical judgments and document sources, confidence, assumptions, and limitations.

Responsibilities:

• Develop and maintain priority intelligence requirements and collection plans with stakeholders; prioritize collection and reporting against mission needs.
• Evaluate government, commercial, open-source, partner, and internal reporting; assess source reliability, corroboration, relevance, and timeliness.
• Track relevant threat actors, campaigns, infrastructure, tools, and tactics, techniques, and procedures; map supported behaviors to MITRE ATT&CK.
• Correlate external reporting with endpoint, network, identity, email, and cloud telemetry to evaluate exposure and support investigations.
• Produce finished intelligence assessments, alerts, actor profiles, and briefings with key judgments, evidence, confidence, gaps, and actionable recommendations.
• Translate intelligence into testable hunt hypotheses and detection requirements; identify expected artifacts, required telemetry, and validation criteria with operational teams.
• Support incident response through adversary context, indicator enrichment, campaign correlation, and assessments of likely follow-on activity.
• Maintain intelligence records and indicators with provenance, timestamps, confidence, relationships, handling restrictions, and review or expiration criteria.
• Coordinate authorized intelligence sharing with customer, government, and industry partners; comply with applicable handling and reporting requirements.
• Maintain SOPs; contribute to capability reviews, exercises, and program evaluations; assess whether intelligence improves operational decisions and defensive coverage.
• Support incident response actions (surge operations).

Qualifications:

Clearance Level: Top Secret (TS) minimum; ability to obtain TS/SCI.

Education: Bachelor's in a technical/managerial discipline + 5 years; HS/GED + 7 years (contract equivalencies apply).

Experience:

All minimum qualifications are required; preferred/highly desired items are not eligibility gates.

• At least 5 years relevant cybersecurity/cyber intelligence experience with a bachelor's degree, or 7 years with HS/GED; contract education equivalencies apply. Includes at least 2 years CTI analysis or substantive cyber threat research supporting security operations, hunting, or incident response; periods may overlap.
• Working knowledge of intelligence lifecycle, requirements, collection planning, source evaluation, analytical confidence, and dissemination.
• Assess sources and independent corroboration; separate facts/assumptions; evaluate alternatives and document uncertainty.
• Research adversary behavior; map evidence-supported MITRE ATT&CK techniques/sub-techniques; distinguish IOCs from behavioral TTPs.
• Understand TCP/IP, DNS, HTTP/S, email, authentication, Windows/Linux, phishing, credential abuse, persistence, C2, and exfiltration.
• Query/interpret SIEM, EDR, or comparable data; correlate times, accounts, hosts, IPs, and authentication outcomes; explain telemetry limitations.
• Use intelligence/research tools for indicator enrichment/validation, infrastructure research, and source attribution; equivalent tools accepted.
• Write concise assessments and brief technical/nontechnical audiences with judgments, mission relevance, confidence, and actions.
• Collaborate with SOC, hunting, detection, or IR staff to produce investigative leads, defensive recommendations, or testable hunt hypotheses.
• Protect sensitive data; follow classification/dissemination rules; maintain reproducible notes and incorporate peer review.

Preferred:

• Three or more years of direct CTI experience, including independently producing finished intelligence and supporting operational consumers.
• Experience developing priority intelligence requirements, collection plans, actor or campaign profiles, and stakeholder feedback processes.
• Experience with Recorded Future, ThreatConnect, MISP, OpenCTI, Analyst1, or comparable platforms, including indicator quality, enrichment, provenance, and lifecycle management.
• Experience with Splunk SPL, Elastic query languages, Microsoft KQL, or comparable query languages to correlate external intelligence with internal telemetry.
• Experience applying structured analytic techniques and frameworks such as the Diamond Model, Cyber Kill Chain, or Pyramid of Pain to specific analytical problems.
• Experience supporting hypothesis-driven threat hunts using PEAK or a comparable structured methodology; ability to identify required data and document findings and limitations.
• Experience translating adversary behaviors into detection requirements or contributing to Sigma, YARA, Snort, Suricata, or platform-specific detection content, with an understanding of validation and false positives.
• Ability to use Python, PowerShell, Bash, APIs, JSON, or regular expressions for enrichment, data normalization, research, or reporting automation.
• Knowledge of STIX/TAXII and intelligence sharing practices, including appropriate Traffic Light Protocol handling and source restrictions.
• Experience analyzing threats involving Microsoft 365, Entra ID, AWS, Azure, or comparable cloud and identity environments.
• Knowledge of malware triage, sandbox reports, network forensics, and attacker infrastructure analysis sufficient to support CTI assessments.
• Experience prioritizing vulnerabilities using exploitation evidence, affected assets, exposure, mission relevance, and available controls.
• Relevant credentials such as GCTI, GCIH, GCIA, CySA+, CISSP, CTIA, or comparable formal intelligence training. These are examples of relevant development and do not independently establish contract compliance.
