The Intelligence Your SIEM Is Sitting On - See What Cyware and Microsoft Are Doing About It at RSAC 2026

TL;DR

Most SIEMs absorb threat intelligence but never give it back. The result is a one-way system where hard-won detections stay siloed, invisible to every other defender facing the same threat. Cyware and Microsoft Sentinel have changed that with a native bi-directional integration that puts shared intelligence to work across the ecosystem. 

Key highlights: 

• Threat intelligence now flows both into and out of Microsoft Sentinel via STIX/TAXII, the same open protocol used for ingestion 

• IOCs and sightings detected in Sentinel are automatically shared into Cyware Intel Exchange for enrichment and redistribution 

• Any STIX-compatible tool in the ecosystem can participate, reinforcing an open standard

Introduction

One of the primary problems facing defenders today is asymmetrical threat intelligence: data goes into the SIEM, but it doesn’t come back out. That means no bi-directional threat intelligence sharing, no cross-border collaboration, and no collective defense. 

Cyware and Microsoft Sentinel teamed up to break this one-way intelligence barrier. The result is true bi-directional threat intelligence sharing between the two top-tier entities, which you can see in real-time at RSA.  

Detection Without Distribution is an Incomplete Defense 

Threat intelligence for one is often threat intelligence for all. 

When analysts gain insight by identifying a novel threat in their SIEM, that information could inform other attacks within the vertical, potentially occurring at the exact same time. 

Historically, this information has often been closely guarded, but the time for infighting is over. As CISA states, “When an organization identifies threat activity and keeps it to itself, our adversaries win.” 

However, in most environments, that hard-won threat intel goes nowhere but the platform that produced it. After investing so much in detections, defenders would do better to invest more in what happens to those detections after they occur: they should be leveraged for all they’re worth. 

That’s why the gap isn’t about detection; it’s about distribution.  

The Asymmetry that Defenders Have Quietly Accepted 

This asymmetrical standard has evolved in the industry over the years. We take it for granted that the investigations, context, insight, and tribal knowledge of our teams will be used for our benefit and our benefit only.  

But despite competitive differences, we are all fighting common cybercriminal adversaries, and what hurts one could hurt all. The danger of being an isolationist is that your organization falls prey to a breach that could have been prevented through participation in the threat intelligence sharing system. 

The technical disparity that creates this paradigm is that threat intelligence flows into SIEMs, improving detection, but no intelligence flows back out. This creates a wasted signal: a phishing campaign detected by one analyst in one company could have been avoided by others across the board.  

The root cause is structural: Threat Intelligence platforms aggregate intelligence from commercial feeds, open-source repositories, and sharing communities, then push it into SIEM platforms like Sentinel via STIX-formatted objects over TAXII.  

But until recently, no equivalent channel existed going the other direction.  

The insights SIEM generates correlating telemetry, identifying anomalies, producing environment-specific IOCs, had no standardized, automated path back out to the broader ecosystem. What couldn't be exported programmatically got shared manually, if at all. 

This paradigm needs to shift, and so do technical capabilities.  

When teams have the tools and ability to get that information back out of the SIEM and into the community, that shared threat intelligence has the power to protect hundreds of others within the same sector and strengthen the web of collective defense. 

What Changes When Intelligence Flows in Both Directions 

The Cyware and Microsoft Sentinel integration turns a unified threat intelligence management platform into a vehicle for threat intelligence sharing and collaboration.  

And it changes one thing: it establishes a standardized, automated path for threat intel to flow back out of internal tools and into the broader defender ecosystem—where it can do the most good. 

The mechanism is based on STIX/TAXII protocols – the same one used to push intelligence into SIEMS in the first place – and formatted for fast, secure, and automated machine-to-machine communication. This takes place via the Cyware Intel Exchange solution. 

This is how it works: 

• Bi-directional exchange via STIX/TAXII: Microsoft Sentinel now has a native capability to export threat intelligence to a TAXII-based destination, establishing architectural symmetry with how intelligence flows in. IOCs and sightings generated in Sentinel are automatically shared into Cyware Intel Exchange, creating a circular intelligence workflow rather than a one-way feed. 

• Automatic ingestion from Sentinel into Cyware Intel Exchange: Intelligence generated in Sentinel flows directly into Cyware Intel Exchange, where it can be enriched, validated, and redistributed, reducing time-to-action from hours to minutes. 

• Defender feed ingestion and enrichment: The integration also pulls in Microsoft Defender Threat Intelligence (MDTI) feeds, which are ingested into Cyware Intel Exchange, automatically enriched, and used to accelerate threat triage. 

Without this mechanism in place, threat intelligence could be shared manually back out to the community via ISACs/ISAOs, threat advisories, and feeds. But what once took hours or days is now reduced to a process of minutes, with no human intervention needed to shepherd it along.  

Attackers move fast. When analysts have access to shared real-world threat data just as fast, defenders stand a chance.  

Standards Matter More than Integrations 

A key benefit is that the Cyware/Microsoft Sentinel integration is built on open standards. It isn’t a proprietary connector that creates yet another new dependency. Instead, any tool compatible with STIX can participate and experience the same collaborative benefits.  

Any intelligence created in Microsoft Sentinel flows into a shared ecosystem, not a private pipeline between two vendors. It is the foundation of open standards that turn point-to-point integrations into community watering holes that benefit sectors, verticals, and industries, instead of creating new siloes.
