The Multi-State Information Sharing and Analysis Center (MS-ISAC) — the primary cyber threat-sharing hub for US state, local, tribal, and territorial governments — has entered what Cybersecurity Dive describes as an uncertain new era after losing its federal funding and thousands of member organizations, according to a June 14, 2026 report.
The organization, operated by the nonprofit Center for Internet Security (CIS), spent roughly two decades as a free, federally supported service before its cooperative-agreement funding through the Cybersecurity and Infrastructure Security Agency (CISA) was cut in 2025, forcing a pivot to a fee-based membership model that many members have evidently declined to join.
Executive Summary
For most of its existence, MS-ISAC functioned as something close to a public utility for government cybersecurity: any state agency, county, city, school district, or tribal government could join at no cost and receive threat intelligence, incident-response support, and network monitoring, with the bill largely picked up by the federal government. That arrangement ended when federal support was withdrawn in 2025, and CIS moved the service to paid membership.
The reported result — thousands of member organizations gone — matters because an information-sharing organization’s value is a function of its network. Every member that drops out is both a blind spot in the collective picture and, potentially, a softer target. State and local governments run elections, water systems, 911 dispatch, courts, and schools; they are also among the most frequent victims of ransomware, precisely because so many of them lack the budget and staff for standalone security programs.
The open question as of mid-June 2026 is whether a smaller, self-funded MS-ISAC can sustain the same defensive footprint — and what happens to the organizations that used to depend on it and now, apparently, go without.
From Public Good to Paid Service — and Why That Math Is Hard
Shared threat intelligence has the economics of a public good: it is expensive to produce, nearly free to distribute, and most valuable when everyone participates. Federal funding solved the free-rider problem by simply paying for universal access. A fee-based model reintroduces it, and with a cruel twist known as adverse selection: the organizations most likely to drop out are the small, resource-poor ones — rural counties, small school districts, modest municipal utilities — which are exactly the entities least able to replace the service on their own and among the most attractive targets for ransomware crews.
None of this means CIS made the wrong call; a nonprofit cannot indefinitely underwrite a national service out of its own reserves once its primary funder exits. But the reported loss of thousands of members suggests the transition is playing out the way the economics would predict. The membership that remains will skew toward larger, better-funded governments, which changes what the shared data represents.
The Collective-Defense Network Effect Runs in Reverse
An ISAC — an Information Sharing and Analysis Center — works because one member’s incident becomes every member’s early warning. A phishing campaign spotted against one county clerk’s office can be blocked at ten thousand others within hours. That flywheel spins both ways: as membership shrinks, the sensor network shrinks, detection gets slower, and the value proposition for remaining members weakens, which can encourage further departures. Managed defensively, a smaller ISAC can still deliver real value to a committed core; managed poorly, shrinkage becomes self-reinforcing.
There is also a national-visibility cost that lands on the federal government itself. MS-ISAC historically served as the aggregation point through which federal agencies understood what was happening across tens of thousands of state and local networks. Fewer members means a dimmer picture — for everyone, including the agencies that cut the funding.
Who Fills the Gap
Three candidates stand out. First, states themselves: the “whole-of-state” model, in which a state CISO extends security services, monitoring, and grant money downward to counties, cities, and schools, has been gaining momentum for years and now has a stronger forcing function. Second, commercial vendors: managed detection and response (MDR) providers, threat-intelligence platforms, and security-focused hosting and connectivity providers will compete for budget that once didn’t need to exist, though public-sector procurement cycles and thin budgets make this a slow, uneven substitution. Third, CISA’s own free services — vulnerability scanning, advisories, regional advisors — which remain available but were never designed to replicate an ISAC’s peer-to-peer sharing fabric.
For infrastructure and security providers, this is a genuine market signal: the public-sector demand for outsourced security operations just grew, involuntarily. The risk is that the gap gets filled unevenly — well-funded jurisdictions buy their way to coverage while the long tail of small governments simply absorbs more risk.
Background
MS-ISAC was established in the early 2000s and grew, under the nonprofit Center for Internet Security, into the designated cyber threat-sharing and defense hub for US state, local, tribal, and territorial (SLTT) governments — a sector spanning tens of thousands of organizations, most of them too small to staff full security teams. Membership was free, underwritten by federal cooperative-agreement funding channeled through the Department of Homeland Security and later CISA, and the center became a fixture of national cyber defense, particularly as ransomware attacks on cities, counties, and school districts escalated through the 2020s.
That model unraveled in 2025 when federal funding was withdrawn amid broader cuts to CISA programs, pushing CIS to a fee-based membership structure. The June 2026 reporting marks a milestone in that transition: the organization survives, but with thousands fewer members and an open question about who now watches over the jurisdictions that left.
