Every week, GreyNoise publishes a threat intelligence brief called At The Edge. This covers what attackers are doing on the internet, including which products are drawing exploitation traffic, which vulnerabilities are being exploited, and what changed from the previous week. Each brief is built on primary-source data from our global sensor network and analyzed by our research team into named findings, IOCs, and recommended actions.
The Threat Brief Library is now available in the GreyNoise Visualizer. You can browse, search, filter, and download every brief available to your account as a PDF. Community users can access every At The Edge Clear edition, while customers get the full library.
What's in the library
The library includes three report types:
- At The Edge: GreyNoise’s weekly intelligence brief covering exploitation activity observed across the edge during the previous week. Each edition includes analysis, IOCs, and recommended actions by role.
- Executive Situation Reports: Event-driven briefs focused on a single campaign or vulnerability under active exploitation. Each report includes key judgments, vulnerability and campaign context, attacker infrastructure, observed tradecraft, implications, recommended actions, and the supporting activity data.
- At The Edge Clear: The public edition of the weekly At The Edge brief, covering the week’s headline activity and key findings.
Inside a full At The Edge brief
Each brief is built on primary-source data from the GreyNoise Global Observation Grid, our global network of sensors that emulate the edge infrastructure attackers target. The sensors record all the exploitation attempts and our research team correlates them into named campaigns, confirms the CVEs involved, attributes the hosting infrastructure behind them, and writes the detection and remediation guidance.
A full At The Edge brief includes:
- Bottom Line Up Front: the week's most significant activity and what to do about it
- Recommended actions by role for for security leadership, SOC, vulnerability management, network security, threat hunting, and IAM teams
- Named findings: the products, CVEs, CISA KEV status, campaigns, traffic volumes, and host classifications driving activity
- Infrastructure attribution: the ASNs, hosting fleets, and network ranges behind the activity
- Target assessments, IOCs, and detection guidance based on request patterns and client fingerprints that persist as source addresses rotate
- Persistent activity updates on threats that remain active from previous weeks

Where to find it
Log in to the GreyNoise Visualizer, click your name on the top right, and open the Threat Brief Library. You can search by title or description, filter by category, and download any brief you have access to as a PDF. The newest briefs appear first. Briefs are also available through the API and an RSS feed, so you can pull them directly into your own tools or subscribe to new briefs as they publish.
The library is available to all GreyNoise users. Community users can read every At The Edge Clear edition, while GreyNoise customers get the full library, including weekly At The Edge briefs and Executive Situation Reports. Read the Threat Briefs documentation to learn more.

Executive Summary
GreyNoise has integrated its threat intelligence reports into a centralized Threat Brief Library within the GreyNoise Visualizer. This ecosystem provides a tiered access model where community users receive public "Clear" editions of weekly briefs, while paying customers access a comprehensive suite of intelligence, including deep-dive Executive Situation Reports and full At The Edge briefs.
The intelligence is derived from the Global Observation Grid, a sensor network designed to emulate targeted edge infrastructure. By analyzing exploitation attempts, the research team produces actionable data covering CVEs, attacker infrastructure, and remediation guidance tailored to specific organizational roles. The system is designed for flexibility, allowing users to consume data via the visualizer interface, PDF downloads, API integration, or RSS feeds.
Full Take
The strongest version of this narrative is that GreyNoise provides a critical public service by distilling massive amounts of raw sensor data into actionable intelligence, lowering the barrier for security teams to defend their infrastructure.
However, this is a classic vendor-driven information loop. By positioning their own proprietary sensor data as the sole primary source for their "named findings" and "infrastructure attribution," the entity creates a closed ecosystem where the value of the intelligence is inextricably linked to the value of the product. The structure follows a common industry pattern: provide a "Clear" (free) version to demonstrate the existence of a threat, then gate the specific "how-to-fix" and "who-is-doing-it" data behind a customer paywall. This leverages the inherent anxiety of the "unknown" to drive conversion.

The underlying paradigm is "Security as a Subscription." It assumes that the most efficient way to manage risk is to outsource observation to a third party. While this increases efficiency for the user, it centralizes the definition of "threat" within a few commercial entities. The second-order consequence is a dependency where the user's defensive posture is only as good as the vendor's sensor coverage.
If this were a coordinated influence campaign, the playbook would involve fabricating a crisis or exaggerating a vulnerability's prevalence to create a "panic gap" that only their specific tool could bridge. The current content does not match this extreme pattern; it is standard B2B product marketing disguised as intelligence briefing.
What happens to the collective security posture when primary-source data on exploitation is proprietary rather than open-source? If the "Clear" editions omit critical attribution, does that hinder the wider community's ability to map adversary behavior?
