Who it fits
From its own pages, GreyNoise sells to enterprise SOCs and to government and national defense operators, with the full platform aimed at organizations of more than 2,500 employees and MSSPs. GreyNoise Block is labelled as being for small and mid-sized teams, and GreyNoise calls it ideal for organizations with fewer than 2,500 employees. GreyNoise says its intelligence plugs into SIEM, SOAR, TIP, and firewall tools that security teams already run. GreyNoise also describes threat hunting teams and vulnerability management teams as users.From its own pages, Intel 471 sells mainly to security teams that want to find and prioritize exposures, track the actors behind attacks, and hunt adversaries in their own environment. Cyber Threat Hunting is tied to the actors coming after a customer's sector, which points to sector-specific hunting programs. Attack Surface Exposure covers assets hosted on-premises, externally and across multiple clouds.

How they differ

CISO Tribune files both GreyNoise and Intel 471 under Threat intelligence as the primary category, and Intel 471 is also filed under Exposure prioritisation and CTEM. GreyNoise sells real-time network threat intelligence built on traffic it observes at the network edge. Its products are GreyNoise Block, which provides blocklists for firewalls, and the GreyNoise Platform, which is used to investigate any IP or CVE. Intel 471 sells Verity471, a platform that connects adversary intelligence across exposure, intelligence and hunting portfolios. Those portfolios are Cyber Threat Exposure, Cyber Threat Intelligence, and Cyber Threat Hunting.

Intel 471 says it goes into the criminal underground and extracts adversary tradecraft at the source. Both companies describe feeding their intelligence into other tools. Intel 471 also offers a library of 700+ ready-built hunt packages tied to actors targeting a sector. GreyNoise offers a 14-day free trial for GreyNoise Block.

GreyNoise is headquartered in Washington, United States. GreyNoise names enterprise SOCs and government and national defense operators as audiences, with the full platform aimed at organizations of more than 2,500 employees and MSSPs. Intel 471 sells mainly to security teams that want to find and prioritize exposures, track the actors behind attacks, and hunt adversaries in their own environment. On July 28, 2026, Intel 471 announced two AI capabilities, MCP471 and Agent471, in its Verity471 platform. On May 6, 2026, it announced Retroactive Threat Detections within Verity471.

What it sells: GreyNoise

What GreyNoise Block does[5][11]
GreyNoise Block turns primary-source edge intelligence from the Global Observation Grid into blocklists for firewalls. Blocklists deploy as standard External Dynamic Lists over HTTPS. GreyNoise says lists refresh every hour. It also offers dozens of out-of-box blocklist templates.
What GreyNoise Platform does[4]
GreyNoise says its platform lets users investigate, enrich, and search GreyNoise's view of the whole internet, for one IP or thousands. Dynamic blocklists turn any GNQL query into a live, API-authenticated URL any firewall or WAF can ingest. Feeds and alerts stream events to a SIEM, SOAR, email, or webhook in real time.

What it sells: Intel 471

What Verity471 does[3][4][9][10][11][15]
Verity471 enables security teams to find the exposures attackers are targeting right now, know the actors and campaigns behind them, and hunt those adversaries in their environment. It synthesizes and centralizes intelligence and puts AI to work helping analysts access and operationalize it faster. It pushes intelligence directly into existing automated systems and AI workflows.
What Cyber Threat Exposure does[1][3][4][8][15]
Cyber Threat Exposure finds the exposures attackers are already circling across a customer's attack surface, vendors, and brand. It identifies exposures such as internet-exposed assets, misconfigurations and critical CVEs and maps them to CTI driven insights. Security teams can prioritize exposures based on real-world threat activity.
What Cyber Threat Intelligence does[1][3][7]
Cyber Threat Intelligence gives visibility into the conversations where attacks are planned. It tells customers who is targeting them, what they are using, and what is already compromised.
What Cyber Threat Hunting does[1][3]
Cyber Threat Hunting provides a library of 700+ ready-built hunt packages tied to the actors actively coming after a customer's sector. Teams hunt threats in their environment with these packages.

About GreyNoise

GreyNoise sells real-time network threat intelligence built on traffic it observes at the network edge. GreyNoise says it watches and analyzes malicious edge traffic in real-time, so customers can block novel exploitation, catch compromised devices, and investigate critical alerts as they happen.[3]

GreyNoise describes its platform as a single place to investigate any IP or CVE, catch threats hitting the edge, and turn intelligence into automated action. On the platform, users can investigate, enrich, and search GreyNoise's view of the whole internet, for one IP or thousands. GreyNoise says its platform returns a first-hand verdict of malicious, benign, or suspicious for any IP looked up.[4]

GreyNoise says a global grid of thousands of sensors observes attackers first-hand. Customers can also deploy GreyNoise sensors that impersonate vulnerable software to draw out attackers, then capture and analyze every packet. GreyNoise says Session Explorer delivers packet-level forensics and full PCAP export across sensor traffic.[3][4]

For action, GreyNoise says dynamic blocklists turn any GNQL query into a live, API-authenticated URL that any firewall or WAF can ingest. Feeds and alerts stream chosen events to a SIEM, SOAR, email, or webhook in real time. GreyNoise says 80+ integrations push its intelligence into SIEM, SOAR, TIP, firewalls, and agentic SOC tools.[3][4][11]

GreyNoise describes several use cases. For alert reduction, GreyNoise says it reduces alert fatigue by classifying IPs as benign, malicious, or suspicious. For threat hunting, GreyNoise says it filters out opportunistic probes, benign scanners, and botnet noise to reveal statistically significant anomalies that represent targeted attacks. For vulnerability prioritization, GreyNoise says that, unlike static severity and probability scores, it supplies real-time, primary-sourced intelligence on attacks it sees in-the-wild.[7][8][9]

GreyNoise also addresses early warning and compromised devices. GreyNoise says its research shows that spikes in traffic targeting older CVEs often precede new CVE disclosures for that same vendor within weeks. For compromised assets, GreyNoise says it uses two signals: an IP that shows up as a scanner in GreyNoise, and outbound traffic that matches a confirmed callback IP. For investigations, GreyNoise says it adds context on IPs and CVEs seen in mass scanning and exploitation campaigns, which speeds triage and reduces manual work.[6][10][12]

GreyNoise Block is labelled as being for small and mid-sized teams. GreyNoise Block turns primary-source edge intelligence from the Global Observation Grid into precision blocklists for firewalls. GreyNoise says blocklists deploy as standard External Dynamic Lists over HTTPS and refresh every hour. GreyNoise says GreyNoise Block is ideal for organizations with less than 2,500 employees, while organizations with more than 2,500 employees or MSSPs are pointed to the full GreyNoise platform. A 14-day free trial is offered for GreyNoise Block.[5][11]

GreyNoise also offers versions of its message for government and enterprise audiences. GreyNoise says it gives enterprise SOCs real-time edge intelligence inside the tools they already run. GreyNoise says it turns edge reconnaissance and exploitation into early warning signals for national defense operators.[1][2][3][5][6][7][9][10][11]
