Collective Cyber Defense for SLTTs
The Multi-State Information Sharing and Analysis Center (MS-ISAC) acts as the operational backbone of Collective Cyber Defense for state, local, tribal, and territorial (SLTT) government organizations. Through trusted collaboration, shared intelligence, and coordinated response, the MS‑ISAC connects SLTT governments to real‑time threat intelligence, 24x7x365 U.S.-based SOC monitoring, and affordable, SLTT‑tailored cybersecurity services, turning shared experience into real‑world protection.
Collective Cyber Defense means no SLTT organization has to defend alone. What one jurisdiction learns helps protect many and strengthens the resilience of communities across the nation. Without Collective Cyber Defense, SLTT organizations face cyber threats in isolation. With it, they defend together — reducing risk, limiting impact, and protecting essential public services.
Stronger Together: A Nationwide SLTT Cybersecurity Community
Trust, Support, and Capacity‑Building
Unlike fragmented or siloed cybersecurity efforts, the MS-ISAC unites SLTT organizations through a trusted, collaborative community. Members don’t just receive information, they contribute to and benefit from Collective Cyber Defense, transforming shared insight into coordinated action. This network fosters real-time collaboration, shared learning, and coordinated defense. Members gain access to peer forums, working groups, and leadership briefings that turn shared insights into coordinated action.
- Whole‑of‑state and cross‑jurisdiction forums that align strategies and raise the security floor statewide
- Peer networks that enable real‑time collaboration, mentorship, and shared problem‑solving
- Coordinated response capabilities that reduce duplication and strengthen resilience at scale
Collaborative Defense and Shared Knowledge
The Connective Tissue of SLTT Cybersecurity
The MS-ISAC is more than a membership, it is the connective tissue of SLTT cybersecurity. We convene the conversations, relationships, and coordination that makes Collective Cyber Defense possible, before, during, and after cyber incidents.. This collaboration turns into action: shared services, mutual aid, and joint response that strengthen resilience and build trust across every layer of government.
- ISAC Annual Summit: Builds trust and peer relationships that enable fast coordination during real incidents
- Member‑only webinars: Deliver SLTT‑specific threat intelligence and practical guidance
- Working groups and communities of practice: Turn shared challenges into shared solutions

Cybersecurity Value for Every SLTT Leader and Sector
Law Enforcement
Collective Cyber Defense ensures law enforcement agencies benefit from what the SLTT community has already seen, learned, and defended against.
Law enforcement agencies operate in a high-stakes environment where cyber threats can have immediate and severe operational consequences. Disruptions to Public Safety Answering Points (PSAPs), Records Management Systems, Computer-Aided Dispatch (CAD), Mobile Data Computers (MDCs), and Jail Management Systems can compromise emergency response, investigations, and public safety. The MS-ISAC delivers solutions designed to protect these mission-critical systems from penetration, disruption, and data exfiltration.
