🌎 In this week's "Improving Security Across Nations with FIRST" video series, we spotlight Tom Millar, Cybersecurity Senior Advisor at CISA and Co-chair of the FIRST TLP SIG.

He shares how a connected community turns individual insight into collective defense:

🚦 Trusted conversations at scale - Helped shape and standardize the Traffic Light Protocol through CISA and the FIRST TLP SIG, a simple set of labels that lets defenders share sensitive information safely, because the more frictionless trust becomes, the faster we can act

📋 Community-powered programs - The KEV Catalog and the CVE Program only work when the community participates; CISA recently launched an online form to make nominating vulnerabilities easier, and is transforming the CVE Program it has led for two decades

🤝 Networks that hold under pressure - When a chain of SharePoint vulnerabilities dropped on a Friday evening in summer 2025, relationships built over years let CISA notify hundreds of entities under active attack

📺 Watch to discover how Tom's journey from Air Force Korean linguist to defending critical infrastructure shows that the network you build is how the mission gets done.

🎉 Excited to announce Season 2 of "Improving Security Across Nations with FIRST." 🌍

We're kicking things off with Esmeralda Kazia, FIRST Member and Director of Monitoring and Incident Response at the Security Operations Center and C-SIRT within Albania's National Cyber Security Authority (AKSK).

She shares how membership has helped transform a young national CSIRT into a trusted regional partner:

🛡️ Structured maturity - Since AKSK joined FIRST's Suguru Yamaguchi Fellowship Program in 2020, membership has shaped almost every aspect of how the team operates, connecting analysts with mentors who helped mature their services in a structured way

🤝 Trust across borders - "The single greatest value of FIRST membership, for me, is trust" — knowing sensitive information is handled responsibly, and that when Albania asks for help, someone answers

🤖 AI-powered defense - Access to FIRST working groups, training and shared intelligence is helping AKSK integrate artificial intelligence into detection and response, strengthening its role as a regional cybersecurity partner in the Western Balkans

📬 FIRST's Q2FY26 Newsletter is here! Here's a look at what's inside:

🎉 #FIRSTCON26 Recap

A look back on the 38th Annual Conference in Denver — five days, 100+ presentations, and lively networking that reflected the event's collaborative spirit. Outgoing PC Chair Merike Kaeo delivered an outstanding program, and Martijn van der Heide now takes the reins to prepare #FIRSTCON27 in Bangkok.

🗳️ AGM & Board Elections

The Annual General Meeting confirmed a refreshed Board: Serge Droz, Carlos Leonardo, and Olivier Caleff re-elected, Mona Elisabeth Østvang returns after a year away, and Logan Wilkins joins for the first time.

👩‍💻 Women of FIRST Mentorship Program

A new 6–9 month mentorship pilot launches in Q3 2026 — interest survey closes July 20.

🏅 Member Spotlight: Art Manion & Jay Jacobs

Two of the driving forces behind FIRST's vulnerability management work: Jay Jacobs (co-Chair, EPSS SIG) and Art Manion (Chair, VRDX-SIG and Vulnerability Coordination SIG). Their contributions to CVSS and EPSS have given the community core frameworks for vulnerability assessment and prioritization, and both have been key organizers of VulnCon — most recently leading a session in Scottsdale titled "A Paradigm Shift in Vulnerability Identity: Why Vulnerability Databases Struggle."

🕰️ New SIG Alert: Time Security

With the Unix epoch overflow arriving January 19, 2038 — plus an NTP rollover as soon as 2036 and a GPS week rollover later in 2038 — the new Time Security SIG is coordinating the community's response. Now 60+ participants strong, its work is already feeding into ITU-T and IEEE standards efforts.

🛡️Additional SIG Updates

✅ Metrics SIG released v1.1, completing metrics coverage across all five CSIRT Services Framework areas
✅ DNS Abuse SIG published v1.3 of the DNS Abuse Techniques Matrix — the first update since 2023
✅ Insider Threat SIG held its inaugural in-person meetup in Denver
✅ EPSS v5 went live June 15 with improved calibration and new exploit-detection signals
✅ Policy SIG published a brief on AI's impact across the cybersecurity ecosystem

🌍 Capacity Building

FIRST launched a new initiative under the G7-ECOWAS Platform for Advancing Cybersecurity, working with ECOWAS and GIZ to support regional cyber confidence-building measures across West Africa.
