How Space-ISAC Is Building Collective Defense for the Global Space Sector with Cyware

The space industry faces a convergence of cyber and physical risks with the potential to take down missions and compromise national security. Space-ISAC recognized this reality and turned to Cyware to build something the sector had never had before: a truly connected, intelligence-driven defense community.

A Threat Landscape Unlike Any Other

The global space sector operates across three distinct and deeply interdependent domains. There is traditional IT security, covering SIEMs, EDR/NDR tools, and identity management. Beneath it sits ground and OT infrastructure: mission-critical systems like Telemetry, Tracking, and Command (TT&C) and mission control. And then there is the domain unique to space itself: in-orbit telemetry, RF interference signals, and Space Situational Awareness (SSA) data.

For most organizations operating in this sector, these three layers exist in isolation. Analysts and mission operators work in parallel, each with their own data streams and their own tools, with no shared view of what the other is seeing. The result is a threat landscape full of blind spots, and adversaries who know exactly how to exploit them.

Space-ISAC was built to address exactly this problem. Grounded in the SPARTA framework, a structured approach to space cyber threat modeling and assessment, its mission is to protect the global space ecosystem through trusted, timely cyber threat sharing and coordinated response. The challenge was doing it at the speed and scale the sector actually demands.

When Manual Processes Cannot Keep Up

Before implementing a unified platform, Space-ISAC and its members faced what many ISACs face: a collaboration model that was decentralized, manual, and far too slow for the threat environment they were operating in.

When a Watch Center alert came in, the process of normalizing it, enriching it with context, and getting it into the hands of members could take anywhere from four to eight hours. By that point, the window for effective response had often already closed.

Inside member organizations, the situation was similarly difficult. Without a way to correlate cyber indicators of compromise with operational anomalies, analysts were left connecting dots by hand. An unusual uplink attempt and an identity management alert might both be present in the data, but no system was drawing the line between them. Alert volumes were high, deduplication was inconsistent, and analyst fatigue was a genuine operational risk.

The sector needed a fundamentally different operating model.

Building the Intelligence-Sharing Hub

Space-ISAC chose to operationalize its mission with Cyware’s Intel Exchange, Orchestrate, and Collaborate solutions, deploying them across two complementary pillars.

The first was a collective defense hub for the ISAC itself. This became the secure, role-based foundation through which Space-ISAC ingests and disseminates indicators, TTPs, advisories, and STIX/TAXII collections across its membership. A dedicated Watch Center normalizes, scores, and tags incoming intelligence with context that matters in the space sector: mission type, asset, supplier, and geography. Members subscribe to relevant feeds that flow directly into their existing security tools, with no manual handoffs and no bottlenecks.

The second pillar was an automated SecOps model designed for member organizations to adopt internally. The platform ingests data across IT, OT, and mission telemetry into a unified view, then uses a correlation engine to fuse cyber IoCs with operational anomalies. When a suspicious uplink attempt pairs with an identity anomaly, the platform triggers SOAR playbooks that can block or quarantine threats, revoke credentials, restrict uplink ACLs, open incident response tickets, and notify both mission operators and the ISAC channel simultaneously.

Underpinning both pillars is a cross-ecosystem collaboration layer that enables secure, inter-member workflows for joint investigations and "flight-control style" incident coordination. Insights and responses flow in both directions, in near real-time, fostering a more connected and responsive community than the sector had previously been able to achieve. This extends beyond Space-ISAC's own membership through Cyware's exclusive ISAC sharing network, the industry's only automated ISAC-to-ISAC operational collaboration platform. With over 85% of global ISACs and ISAOs running on Cyware, Space-ISAC can share and receive malware advisories, vulnerability alerts, IoCs, and threat mitigation strategies with peer communities across sectors, including healthcare, energy, maritime, and aviation, in real-time and under full TLP 2.0 controls. When a threat crosses sector boundaries, Space-ISAC is already connected to the communities that need to know.

The Numbers That Tell the Story

The results since implementation have been significant and measurable.

Time-to-share indicators dropped from four to eight hours down to just five to thirty minutes. Mean Time to Detect fell from sixty to ninety minutes to twenty to thirty minutes, made possible by correlating signals across IT, OT, and mission telemetry that had previously lived in separate silos. Mean Time to Respond followed a similar trajectory, shrinking from four to eight hours to thirty to sixty minutes through automated SOAR playbooks.

Between sixty and eighty percent of critical alerts are now automatically disseminated to subscribed members in near real-time. The platform has also reclaimed an estimated eighty to one hundred analyst hours per month, time previously consumed by duplicate alerts, manual enrichment, and fragmented workflows.

“With Cyware, we’ve moved from siloed data to fused intelligence. Our members can now anticipate and neutralize threats before they impact missions. It’s a paradigm shift from reactive defense to proactive mission assurance.” — Space-ISAC

A Repeatable Blueprint for the Sector

The 90-day rollout plan that guided Space-ISAC’s implementation offers a clear path for any organization in the sector looking to adopt a similar model.

The first two weeks focus on discovery: inventorying feeds across all domains and identifying the highest-value use cases for correlation. Weeks three through six cover connection and normalization, standing up the platform, connecting to data sources, and normalizing everything to standards like STIX 2.x. The following month shifts to correlation and automation, authoring cross-domain rules and implementing SOAR playbooks. The final stretch is about going live, measuring outcomes, and socializing those wins to sustain leadership buy-in.

Several lessons stand out from Space-ISAC’s experience. Starting with a manageable number of high-value use cases, rather than attempting to solve everything at once, makes early wins achievable. Treating deduplication and scoring as primary objectives reduces alert fatigue and has a measurable impact on analyst performance. Establishing redaction rules and sharing protocols before an incident happens ensures that real-time sharing is possible when it matters most. Regularly measuring and communicating improvements in MTTD, MTTR, and analyst efficiency is what keeps both leadership and the broader community engaged over the long term.

From Reactive to Proactive

The space sector has long understood the complexity of its threat landscape. What Space-ISAC has demonstrated is that a defense posture built around collective intelligence and automation can match that complexity.

By replacing fragmented, manual collaboration with a unified platform, Space-ISAC has given its members the ability to act on intelligence together, before missions are impacted. The Cyware-powered model, aligned to the SPARTA framework, now serves as a blueprint that other space organizations can follow to advance their own collective defense posture.
