  • Episode 67 — Exam-day tactics to maximize your score
    Feb 8 2026

    The transition from months of intense study to the actual day of the GCTI assessment requires a shift from learning mode to performance mode, where technical expertise must be demonstrated under the constraints of a high-stakes, timed evaluation. This episode provides practical advice for navigating the assessment, such as reading every question twice to identify specific qualifiers like "not" or "most likely" that define the correct answer. We discuss the "marathon" mindset, where you pace yourself through the four-hour window and use the "mark for review" feature for exceptionally difficult questions to avoid a late-exam time crunch. Understanding the digital testing interface is essential, particularly for the CyberLive hands-on lab sections which require you to perform live analysis on a virtual machine. Best practices include using the process of elimination to narrow down technical choices and trusting your first professional instinct when evidence is balanced. By mastering these exam-day tactics, you ensure that your analytical rigor translates into a successful certification outcome.

  • Episode 66 — Deliver high-impact briefings under time pressure
    Feb 8 2026

    The ultimate test of a senior intelligence professional is the ability to distill weeks of technical forensic work into a few moments of high-stakes communication. In the professional world of cybersecurity, you will often find yourself in situations where a critical decision must be made, and you have only a brief window to influence the outcome. Typically, a seasoned cybersecurity educator will explain that "brevity is the soul of intelligence," meaning if you cannot explain the threat and the required response in the time it takes to ride an elevator, you risk losing the attention of the leaders who need your guidance most. By mastering the art of the high-impact briefing, you ensure you can command the room and drive the security mission forward even under extreme time pressure. This involves preparing a one-minute "elevator pitch" that covers the technical threat, the specific risk to the business, and a clear recommendation for action. For the GCTI exam, you must demonstrate the ability to prioritize the most critical information and pivot your delivery based on the audience's needs.

  • Episode 65 — Close stakeholder feedback loops for iteration
    Feb 8 2026

    The final stage of a mature intelligence lifecycle is the closing of the feedback loop, where stakeholder input is used to drive the continuous improvement and iteration of your analytical products. This episode focuses on the "service-oriented" nature of intelligence, emphasizing that your reports must evolve as the needs of your audience and the tactics of the adversary shift. We discuss how to use formal meetings and surveys to capture "user experience" data, identifying which parts of your reports are helping leaders decide and which parts are considered "technical noise." For the GCTI exam, you should understand how feedback is used to refine original intelligence requirements and to retire collection efforts that are no longer adding value to the mission. Practical application involves maintaining a "change log" to show your stakeholders that their input is directly shaping the technical direction of the intelligence team. By closing the feedback loop for iteration, you ensure that your program remains a sharp, indispensable, and highly relevant instrument for the defense of the enterprise.

  • Episode 64 — Handle sensitivities and caveats without friction
    Feb 8 2026

    Managing the sensitivity of intelligence data is a non-negotiable professional requirement, necessitating the use of the Traffic Light Protocol (TLP) to ensure that caveats and sharing restrictions are clearly understood by all parties. This episode breaks down the four TLP color codes—RED, AMBER, GREEN, and CLEAR—and provides specific scenarios for when to apply each label to your internal and external reports. We discuss the "trust cost" of ignoring these caveats, explaining how a single unauthorized disclosure can permanently burn bridges with valuable intelligence sources and partners. In a certification context, you must be able to assign the correct TLP level to a report based on the risk of the information being exposed to an adversary or a competitor. Troubleshooting involves training your entire team on the specific meaning of these labels to prevent accidental "data spills" through human error or misinterpretation. By handling sensitivities with technical and administrative discipline, you maintain the "circles of trust" that are essential for the ongoing exchange of high-fidelity, high-stakes information.

  • Episode 63 — Exchange intelligence using standards that travel
    Feb 8 2026

    To achieve the speed and scale required for modern defense, intelligence must be exchanged using universal technical standards that allow disparate security tools to communicate without manual translation. This episode focuses on the implementation of the STIX (Structured Threat Information Expression) and TAXII (Trusted Automated Exchange of Intelligence Information) protocols, which serve as the "lingua franca" of the threat intelligence community. We explain how STIX provides a machine-readable way to describe the relationships between actors, campaigns, and indicators, while TAXII serves as the transport mechanism to move that data across the network. For the GCTI exam, you must understand the "object-oriented" nature of these standards and how they enable automated ingestion and blocking at the network perimeter. Practical application involves verifying that your threat intelligence platform and defensive sensors support the latest versions of these standards to ensure maximum interoperability with external partners. By using standards that travel, you remove the technical friction from the sharing process and enable a truly machine-speed response to emerging threats.

  • Episode 62 — Share intelligence through trusted, auditable processes
    Feb 8 2026

    Collaborative defense depends on the secure and auditable exchange of threat data with trusted partners, requiring a strict adherence to protocols that protect both the information and the organization’s reputation. This episode examines the establishment of "circles of trust" within Information Sharing and Analysis Centers (ISACs) and the importance of having a clear understanding of how shared data will be used by the recipient. We discuss the use of centralized platforms to maintain an audit trail of every indicator that leaves the enterprise, allowing for the retraction or update of information if the technical ground truth later changes. For the GCTI exam, you should be familiar with the legal and ethical considerations of sharing, including the impact of non-disclosure agreements and the "Traffic Light Protocol" for sensitivity management. Real-world best practices involve joining local sharing communities to benchmark your own processes against industry peers and to gain access to early-warning signals that are not yet in public feeds. By sharing through trusted processes, you contribute to a collective immune system while ensuring your organization's sensitive data remains secure.

  • Episode 61 — Measure intelligence impact with meaningful feedback
    Feb 8 2026

    Measuring the true value of a threat intelligence program requires moving beyond vanity metrics, like the volume of reports produced, and focusing on the tangible impact your work has on organizational risk. This episode explores the transition from quantitative counting to qualitative assessment, where success is measured by the number of "intel-led" detections or the strategic decisions influenced by your findings. We discuss how to track specific security alerts that were prevented or contained because of your technical foresight, providing a clear ledger of prevention for your stakeholders. In a GCTI context, you must demonstrate the ability to map your success metrics directly back to the original intelligence requirements to prove that you are solving the right problems. Troubleshooting involves creating a formal feedback loop, such as a "post-briefing survey," to identify any analytical blind spots or communication gaps that need to be addressed in future iterations. By measuring impact with discipline, you justify the ongoing investment in your team and ensure your analytical products continue to mature alongside the adversary.
