GreyNoise for Enterprise

Faster Detection & Response for the Modern SOC

Edge devices are the most exploited technology category in 2026. GreyNoise gives enterprise SOCs real-time edge intelligence inside the tools they already run, so they can defend against novel exploitation, detect compromised devices, and investigate critical alerts.

The Challenge

The edge is your blind spot

You have mature detection and response across endpoint, identity, cloud, and data. The edge is different. It's where you have limited telemetry, and it's where attackers move first.

Time-to-exploit is near zero

AI has collapsed time-to-exploit. New vulnerabilities are weaponized the moment they appear, faster than teams can detect, prioritize, and respond.

Time-to-exploitday zero
Disclosure Weaponization Widespread
0exploitation attempts

No agents at the edge

VPNs, firewalls, routers, and load balancers can't run EDR. Your most exposed attack surface has the least telemetry.

Alert overload

Mass internet scanning floods the queue. Analysts burn hours separating noise from threats that matter.

Capabilities

Everything you need to defend the edge

Defend

Defend against novel exploitation

GreyNoise spots active exploitation the moment it starts and turns it into dynamic, vulnerability-specific blocklists. Push them to the edge in real time, before attackers gain momentum.

Detect

Detect compromised assets on your edge

Edge devices can't run EDR, so compromise usually surfaces too late. GreyNoise catches it with high-fidelity signals: an asset scanning our global sensor grid or beaconing to known C2. Act on it immediately, no agent required.

Investigate

Triage and investigate alerts

Most edge alerts are mass-scanner noise. GreyNoise rules out the benign background noise and enriches what remains with intent, CVE, and tooling context. Analysts cut volume and zero in on the alerts that demand action.

SIEM & SOAR

Surface urgent threats. Automate the response.

GreyNoise streams live scanning and exploitation activity into your SIEM to sharpen detections, and into your SOAR to drive confident, automated action.

Reduce alert volume, surface targeted threats

Perimeter alerts are overwhelmingly noise. The events worth investigating get buried under opportunistic mass scanning.

1
FW / WAF logs
2
Filter to inbound internet traffic
3
GN
Match source IPs against GreyNoise
4
Exclude known scanning
5
Prioritize remaining events by source-IP volume
●  Signal

Fewer alerts, better signal-to-noise ratio. Every remaining alert is from an IP GreyNoise has never observed — a stronger signal of potential targeted reconnaissance or attack activity.

Detect allowed inbound from known-malicious hosts

Nothing checks whether traffic the firewall let through should have been, even when the source IP has a documented history of malicious activity.

5
Prioritize by source-IP volume
●  Signal

Known-malicious IPs the firewall let through. Sessions to investigate, rules to fix.

Flag authentication from compromised hosts

Auth attempts never stop, and opportunistic access looks like targeting. Scanners, botnets, and proxy hosts authenticate to VPNs and identity providers unflagged.

1
VPN / IdP auth logs
2
Filter to authentication events
3
GN
Match source IPs against GreyNoise
4
Include not-spoofable matches
5
Prioritize by source-IP volume
●  Signal

A successful login from a flagged IP. An immediate, high-priority alert.

Detect outbound connections to threat infrastructure

Outbound volume is too high to check by hand, and most threat feeds lack the real-time behavioral data to know which connections warrant a look.

1
Outbound / EDR logs
2
Filter to public connections not blocked by egress
3
GN
Match destination IPs against GreyNoise
4
Surface malicious matches
5
Prioritize by internal source-IP volume
●  Signal

Outbound to known-malicious infrastructure. Possible C2, exfil, or botnet.

IP enrichment for faster triage & response

Analysts look up IPs by hand, burning time on routine enrichment and making inconsistent calls.

1
Alert fires
2
GN
/v3/ip lookup (single or bulk to 10K)
3
Classify: classification, tags, threat level
4
Route by decision path
5
Enrichment written to case
●  benefit

Faster response, consistent triage across shifts, and 40 to 60% less alert volume.

Early warning on vendor CVE exploitation spikes

Global exploitation surges against your vendors' CVEs are often the first sign of novel or zero-day activity. A single org can't see them until it's too late.

●  benefit

Spot rising exploitation early and harden before mass attacks, with real threats auto-separated from benign scanning.

Detect compromised edge devices

Compromised edge devices scan the internet or call home to attacker C2 undetected. EDR can't run on them, so you usually find out only when you're blacklisted or reported by an outsider. GreyNoise watches both directions.

Power agentic workflows

Agentic workflows need high-quality threat intelligence. Without it, agents act on incomplete context or low-confidence data.
