June 2025 TRU Intelligence Briefing On-Demand

As cyber threats grow in volume and sophistication, organizations need more than periodic scans and reactive patching. Continuous Threat Exposure Management (CTEM) offers a proactive, structured approach to reducing risk across your entire attack surface – people, processes, and technology.

In this fireside chat webinar, Tia Hopkins and Bernard Montel discussed the importance of CTEM in enhancing cyber resilience and why the five stages of CTEM (i.e., scoping, discovery, prioritization, validation, and mobilization) are crucial for aligning security with business goals. They also highlight the role of Managed Detection and Response (MDR) in providing real-time visibility and prioritization based on actual threats.

Key topics discussed:
- The five essential stages of the CTEM framework – scoping, discovery, prioritization, validation, and mobilization – and why you can’t buy resilience in a box.
- How the expanding and complex attack surface demands a continuous, risk-based approach.
- How CTEM aligns with the NIST framework to help anticipate, withstand, recover, and adapt to cyber incidents.
- Use cases where real-world threat data enhances CTEM prioritization and how CTEM improves MDR operations.
- How exposure platforms map asset relationships to uncover and close critical vulnerabilities before they’re exploited.

Watch this webinar on-demand to learn how your organization can implement Continuous Threat Exposure Management (CTEM) to enhance your security outcomes, build cyber resilience, and prevent business disruption.

May 2025 TRU Intelligence Briefing - May 13th

As the cyber threat landscape evolves, organizations must move beyond traditional vulnerability and risk management programs to a more dynamic, continuous approach to risk reduction. Continuous Threat Exposure Management (CTEM) is a structured methodology that enables security teams to identify, prioritize, and mitigate exposures before they can be exploited.

In this webinar, Tia Hopkins, Chief Cyber Resilience Officer and Field CTO at eSentire, breaks down the five stages of the CTEM framework and demonstrates why CTEM is a critical component of a modern cybersecurity strategy.

Key discussion topics include:
- Learning how the CTEM framework’s five stages help organizations continuously assess and mitigate risk
- Discovering how to transition from vulnerability management to exposure management and CTEM
- Understanding what CTEM is and why it’s a game-changer for modern cybersecurity strategies
- Exploring how CTEM enhances MDR to create a more comprehensive security posture
- Gaining actionable insights on how to build a resilient security program that anticipates, withstands, and recovers from threats effectively

Watch this on-demand webinar to learn how your organization can build cyber resilience by integrating CTEM into your cybersecurity strategy.
