Key findings

Full analysis
Overview
The website is the official-looking homepage and documentation portal for ZeroMQ, an open-source universal messaging library. It presents technical documentation, community resources, usage guidance, and project information for software developers, including socket-based messaging across in-process, inter-process, TCP, UDP, multicast, and WebSocket transports, with patterns such as publish-subscribe, request-reply, and task distribution.
Scam/Impersonation Risk
No phishing, impersonation, malicious-site, or identity-contradiction signals were observed. The content is technically coherent with an established open-source software project, contains no login or sensitive-data form, and presents no financial, investment, or deceptive commercial mechanism. One external reputational signal concerns abuse reports associated with a shared data-centre address rather than the website's content; the attribution is to shared infrastructure, so it does not establish malicious activity by this site.
- The homepage identifies ZeroMQ as an open-source messaging library and provides substantive documentation topics, with no detected fraud indicators.
- The homepage contains no login form, sensitive form, hidden form, wallet interaction, or suspicious script behaviour.
- The site's domain was registered through Gandi SAS on 2007-05-10 and is recorded as 19.28 years old.
- A shared hosting IP associated with the site has 644 abuse reports; the reports are attributed to shared infrastructure operated for data-centre/web-hosting use, not specifically to the site.
Regulatory Verification Notes
The available material supports an established, apparently legitimate informational software project rather than a regulated financial-service provider. The site presents project-level identity through the ZeroMQ name, documentation, community references, and links to external project channels, but the real-world operator identity is not independently verified. No financial-services licensing claim or registration number is presented in the reviewed material; for this business model, that is a transparency and applicability point rather than evidence of fraud. The domain's long registration history, reputable registrar, established traffic footprint, clean external threat checks, and valid transport encryption are consistent with a mature public-facing project.
- The homepage describes community-backed open-source software and identifies “The ZeroMQ authors” as the copyright attribution.
- Domain registration: 2007-05-10T15:21:14Z; expiration: 2031-05-10T15:21:14Z; registrar: Gandi SAS.
- The site is served through AS16509, Amazon.com, Inc. (AMAZON-02 - Amazon.com, Inc., US).
- TLS uses issuer YE2 with DV validation and is valid until 2026-10-03T11:55:28+00:00.
What to Verify Next
Before credential or payment interactions, ordinary independent checks should confirm that the project identity and any associated account or transaction destination are referenced through established project channels rather than an unsolicited source. Any sponsorship, donation, or commercial arrangement should also be checked for a clearly identified counterparty, applicable terms, refund conditions, and payment-provider protections. If the site is used to obtain software, package provenance and release authenticity should be confirmed through the project’s independently linked development repository.
- The homepage links to GitHub and Twitter as external project channels.
- The homepage provides a guide, wiki, community resources, and code-of-conduct material that can be used for independent project confirmation.
- The reviewed page contains no sensitive transaction form, so any later payment or account workflow should be assessed separately at the point of interaction.
Summary Verdict
The overall posture is high trust and low risk, with the available evidence consistent with an established, apparently legitimate open-source project. No contradictory scam or impersonation indicators were identified, although the operator’s real-world identity remains not independently verified.
Infrastructure Integrity
The website is protected by AWS CDN/WAF infrastructure, with observed edge addresses in AS16509 and no origin candidate identified in the infrastructure assessment. This is a mitigating control that reduces direct exposure of the underlying service, but it is not, by itself, proof of legitimacy.
Closing Assessment
Normal informational use is proportionate to the assessed posture; credential or payment activity should follow ordinary independent counterparty, terms, and payment-protection checks.

About this assessment
A trust score summarises the evidence TrustSniffer could collect about zeromq.org at assessment time. It is a starting point for your own judgement, not a guarantee: a high score means the signals were consistent with a legitimately operated site, a low or critical score means several risk patterns were present.
TrustSniffer assesses a website from the evidence it can collect at a point in time: domain registration and age, hosting and certificate, the content the site served, and third-party reputation feeds. A score is a summary of that evidence, not a guarantee and not a legal finding. There is no human rating and no user review in it. A site can change after it is assessed.
