KNOW MORE NOISE

GreyNoise is THE source for understanding internet noise.


SOLVING INTERNET NOISE

We collect, analyze, and label data on IPs that scan the internet and saturate
security tools with noise. This unique perspective helps analysts waste less
time on irrelevant or harmless activity, and spend more time focused on targeted
and emerging threats.

INCREASE ANALYST EFFICIENCY

GreyNoise helps analysts recognize events not worth their attention. Indicators
in GreyNoise are likely associated with opportunistic internet scanning or
common business services, not targeted threats. This context helps analysts
focus on what matters most.

FIND COMPROMISED DEVICES

If we see your device scanning the internet, it's likely compromised. GreyNoise
notifies analysts when an IP they care about shows up in our collection, helping
security teams respond quickly to compromises.


SEE EMERGING THREATS

Security teams can uncover tradecraft seen across the internet through our
GreyNoise Query Language (GNQL). Our tags reveal IPs looking for and exploiting
vulnerabilities. Security teams can assess their exposure as they monitor
progressive threat activity.


HOW IT WORKS

Our insight is delivered through our API, integrations, and visualizer from two
distinct datasets:
Internet Background Noise
RIOT (Common Business Services)


INTERNET BACKGROUND NOISE

GreyNoise’s internet-wide sensor network passively collects packets from
hundreds of thousands of IPs seen scanning the internet every day.

Companies like Shodan and Censys, as well as researchers and universities, scan
in good faith to help uncover vulnerabilities for network defense. Others scan
with potentially malicious intent. GreyNoise analyzes and enriches this data to
identify behavior, methods, and intent, giving analysts the context they need to
take action.


RIOT (COMMON BUSINESS SERVICES)

RIOT provides context to communications between your users and common business
applications (e.g., Microsoft O365, Google Workspace, and Slack) or services
like CDNs and public DNS servers. These applications communicate through
unpublished or dynamic IPs, making it difficult for security teams to track.
Without context, this harmless behavior distracts security teams from
investigating true threats.

CUSTOMERS

“Using GreyNoise Intelligence helps the Hurricane Labs team eliminate background
noise and focus on the most actionable and relevant alerts for our customers.

Rather than presenting our analysts with even more data to investigate,
GreyNoise decreases the volume of alerts that are triggered–which makes for a
happier and more effective SOC team.”
— STEVE MCMASTER, Director Of Managed Services

noisy activity related to scanners, botnets or harmless business services—saving
the analyst from chasing irrelevant deadends and leaving more time to
investigate true threats."
