When a cyber breach goes unaddressed, the consequences can escalate quickly, from data exposure and operational downtime to increased strain on already limited IT resources. Rapid response and shared intelligence are essential to limiting impact. During the PowerSchool breach, our team provided critical incident response support to help a K–12 member understand the threat, assess potential impact, and take informed next steps. This case study highlights how community‑driven defense and coordinated response strengthen cyber resilience across education. https://bit.ly/4wi0epp #CyberDefense #K12Tech #CollectiveCyberDefense

Stronger cyber resilience starts with real‑world insight. Join us at the ISAC Annual Summit as we welcome keynote speakers who bring firsthand experience from across the cyber ecosystem including government, law enforcement, and industry. Day 1 Theresa Payton, former White House Chief Information Officer, will share perspectives on how collaboration across technology, security, and AI helps organizations respond more effectively to evolving cyber risks. Day 2 Chris Tarbell, former FBI Special Agent, and Hector Monsegur, cybersecurity expert, will lead a candid CyberChat on how attacks unfold and what leaders can do to strengthen defenses and reduce risk. Meet us in Orlando, FL on June 21. Reserve your spot now: https://bit.ly/42NArIo

Our community of SLTT organizations face growing cyber threats that no single entity can tackle alone. Through the collaborative approach of Collective Cyber Defense we can strengthen resilience, share actionable intelligence, and respond faster to emerging risks. In this featured story from the Spring 2026 issue of Cybersecurity Quarterly, SVP of MS-ISAC Strategy and Plans Carlos Kizzee explores how collaboration, trust, and shared responsibility help advance Collective Cyber Defense across the SLTT landscape and why it’s essential to protecting critical services and communities.

Public safety agencies operate in environments where cyber incidents can disrupt emergency response, life safety, and public trust. In this webinar, CIS experts discuss how analyst led security operations, shared intelligence, and always on monitoring help agencies reduce risk and maintain continuity of operations across mission critical systems.

Cyber defense is stronger when it’s shared. A former state CISO shares how transitioning from the private sector to state government made one thing clear: success depends on leaning on each other. With a small team and limited resources, having a central organization monitoring the threat environment on behalf of all states makes a critical difference. That’s the power of Collective Cyber Defense: shared intelligence, shared vigilance, and shared strength. Learn more about Collective Cyber Defense, including the four pillars that make it possible. https://bit.ly/4ss0Ndh #CollectiveCyberDefense #PublicSectorCyber #MSISAC

New Threat Alert for U.S. SLTT macOS Users! A MacSync stealer campaign is actively targeting macOS users across SLTT environments, putting credentials and systems at risk.

Cyber resilience is built long before an incident occurs. It grows through trust, shared experience, and a commitment to supporting one another when challenges arise. With more than 5,000 MS-ISAC members, our community continues to demonstrate how collaboration and shared knowledge strengthen cyber readiness nationwide. Learn how this growing community stands strong together against an evolving threat landscape. https://bit.ly/3QVmvtb #CollectiveCyberDefense #MSISAC #PublicSectorCyber

If you’re an IT or security leader in a city that hosts concerts, festivals, or major sporting events, you know the pressure well: tight timelines, fragmented tools, limited authority over airspace, and the expectation to stop threats you can’t always see. Drones add a new layer of risk that legacy security programs weren’t designed to manage like bypassing physical perimeters, straining detection capabilities, and requiring coordination across agencies that don’t always share systems or data. For many SLTTs, it’s not a lack of awareness, it’s a lack of integrated guidance and operational clarity. A report from the Center for Internet Security breaks down how Unmanned Aircraft Systems risks are evolving and provides actionable guidance for SLTT governments to improve detection, information sharing, and readiness for large public gatherings. https://lnkd.in/e4NGs4KT #CollectiveCyberDefense #PublicSafety #RiskManagement

Small and mid‑sized communities face the same threats that larger cities do, just with fewer resources. That’s why the City of Pleasanton turned to MS‑ISAC to strengthen its cyber defenses. Watch the video to see how the MS‑ISAC community helped boost their cyber resilience. https://bit.ly/42StEwY #CyberResilience #CollectiveCyberDefense #PublicSectorCyber
