Mass Internet Scanning & Exploitation
is a Major Problem for Cybersecurity Teams
70% of SOC alerts are false-positive or low priority.
Edge exploitation is on the rise
According to Verizon DBIR 2025, exploitation of edge vulnerabilities in breaches has surged eightfold.
Exploitation is fast but patching is slow
50% of new vulnerabilities have a known exploit within one day while patching happens over weeks.
Threat Intel is often stale & incomplete
CVSS and EPSS scores can take weeks or months to accurately reflect current activity in the wild
A Real-World Example of Mass Exploitation in Action
Mass exploitation enables rapid escalation of vulnerabilities, both new and old. In this case, a newly disclosed vulnerability saw an instant rise in attacker interest — growing 10X in a matter of days.

Use Cases
GreyNoise auto-filters SIEM noise for a 70% alert reduction, providing one-step IP lookups with rich context, enabling confident threat escalations and a 40% faster MTTR.
Early Warning System for CVEs of Interest Being Actively Exploited
GreyNoise delivers real-time reconnaissance intelligence for CVEs, empowering your team to preemptively patch vulnerabilities and act before widespread exploitation.
Dynamically Block 0-Days and Novel Exploits
GreyNoise delivers real-time exploitation intelligence to confirm active 0-day and novel exploits, enabling dynamic blocking and rapid risk mitigation before a patch is available.
Detect Compromised Assets in Your Own IP Space
GreyNoise helps you identify compromised assets in real-time by detecting when your IPs engage in malicious external scanning, providing rich threat intelligence to enable rapid containment and mitigation.
Reduce SIEM Logging & Lower SIEM Costs
GreyNoise optimizes your SIEM by pre-filtering benign traffic, reducing log volume and storage costs, and ultimately improving detection fidelity so your team can focus on real threats.
Prioritize Actively Exploited Vulnerabilities
GreyNoise provides real-time exploitation intelligence, that often beats KEV, to prioritize critical vulnerabilities based on current threat activity, enabling rapid patching and mitigation.
Context Enrichment in IR Workflows Reducing Time to Response
GreyNoise provides instant IP context to reduce incident investigation time, enrich threat intelligence, and streamline containment by cutting through the noise.
Conduct Threat Hunting and Identify Attacker Infrastructure & TTPs
GreyNoise provides real-time attacker infrastructure intelligence, identifying and classifying malicious IPs, mapping their TTPs, and linking reused infrastructure for enhanced threat hunting and soft attribution.
Not all alerts are created equal
GreyNoise makes it easy to distinguish between benign and malicious traffic so you can focus on the real threats.
- Filter out noisy alerts from benign scanners
- Elevate alerts from malicious scanners probing for CVEs of interest
- Block malicious IPs doing mass scanning and exploitation

Is it really cRiTiCaL?
GreyNoise monitors internet scan activity in real-time to provide you with the best signal on the likelihood of exploitation of the vulnerabilities you care about.
- Prioritize critical patches by understanding active exploitation trends
- Dynamically block malicious IPs mass scanning for a specific vulnerability
- Monitor CVEs and get alerted when it's being actively exploited
- Search for IPs that may have already breached your perimeter
Needle in the haystack. Found.
Use GreyNoise to accelerate your threat hunting. We tag everything we see, you can query against any tag. This means looking for any anomaly or correlation is just a few queries away.
- Kickstart threat hunting workflows with insight into scanning trends and anomalies
- Uncover attacker infrastructure and understand historical scanning activity
- Filter out noise and focus on events of interest in your SIEM or SOAR
