Based on G2 reviewer demographics, GreyNoise's pricing is best suited for mid-market security operations teams in industries like financial services, logistics, education, and telecommunications. These teams handle high volumes of inbound connection attempts and benefit most from noise classification, SIEM integration, and CVE-linked alerting. G2 reviews of GreyNoise show strong adoption among SOC analysts and threat intelligence practitioners who need to reduce false positive escalations at scale. Enterprise buyers at complex organizations also appear in G2 data praising GreyNoise's detection accuracy. Small businesses and nonprofits with lean security budgets find GreyNoise valuable but frequently cite pricing as a barrier relative to their team size.
GreyNoise offers a free community tier alongside paid plans requiring custom quotes. According to G2 users, the free tier provides basic IP lookup and noise classification but carries meaningful limitations: shallow historical data retention, scan quotas that create bottlenecks, and restricted access to advanced tagging, enrichment depth, and API throughput. G2 reviewers note that the free tier suits individual analysts doing spot checks, while GreyNoise's paid plans unlock SIEM and SOAR integrations, RIOT classification, bulk IP analysis, CVE monitoring feeds, and extended IP history. A free trial is available for teams evaluating GreyNoise's full capabilities before committing to an enterprise custom quote.
G2 reviewers rate GreyNoise at 4.5 out of 5 overall, signaling strong satisfaction despite recurring cost concerns. Mid-market security and operations teams consistently report significant ROI through reduced analyst hours, fewer false positive escalations, and faster triage. G2 reviews of GreyNoise indicate the value proposition is clearest for teams drowning in alert noise, with multiple reviewers citing dramatic reductions in manual investigation time. However, small businesses and nonprofits on G2 flag GreyNoise's pricing as steep relative to their budgets. One reviewer explicitly noted the modular pricing structure feels designed to charge separately for each capability, which compounds cost concerns for resource-constrained teams.
I’ve found it to be extremely reliable in detecting adware, ransomware and viruses. It is always up to date on new malware circulating online. Review collected by and hosted on G2.com.
It is not major, but sometimes it can weigh down the operating system during scanning. Review collected by and hosted on G2.com.
I am writing this as the air conditioning in our server room hums extremely loudly and is distracting. To be honest the sandbox did not crash on me when I was doing malware analysis which is good news since most of the tools I have worked with do and I have to restart everything. Also the summary output from the AI assistant is very readable and I no longer have to read through 100 logs which consumes a lot of time. Review collected by and hosted on G2.com.
The dark theme (dark mode) is always set back to bright white upon logging in and it is very frustrating so they should fix this bug as quickly as possible.The price point of this application is simply too high in comparison to what you receive and it appears that the developers broke the product into a number of different modules so they could charge you for each one individually. In addition it becomes extremely slow and cumbersome if you are trying to perform a series of complex or multi-query searches at once. Review collected by and hosted on G2.com.
