cwi.nl Overview

Description of cwi.nl

cwi.nl appears to be the official website of Centrum Wiskunde & Informatica (CWI), the national research institute for mathematics and computer science in the Netherlands. The homepage screenshot, domain branding, and page text indicate that the site presents institutional information about research, education, events, collaborations, and organizational news.

Based on the visible content and classification data, the website serves as an academic and technology-focused information portal rather than a commercial service. It appears to be operated by CWI itself, with content related to scientific research, doctoral events, educational activities, and public-facing institutional resources. The long-established .nl domain and strong Dutch academic context are consistent with a legitimate research organization website.

Safety Assessment for cwi.nl

The available scan results are strongly favorable at the time of this scan. The domain was not flagged by any of 91 security engines, the malware scan reported no flagged files, and the checked threat-database and blacklist sources did not report known phishing or malware-related listings. The site also carries consistent categorization as education, technology, and research-related content across multiple web-classification providers.

Additional context also supports a lower-risk assessment: the domain is very old, has a strong traffic presence, and the visible page content matches an established academic institution rather than a deceptive login page, giveaway, or storefront. No suspicious external links or iframes were reported in the provided scan summary.

Based on available data, no threats were detected at the time of this scan.

Technical Description

The site uses a valid SSL/TLS certificate that is current through 2026-12-07, which indicates that encrypted connections appear to be supported. DNSSEC is signed, which adds integrity protection at the DNS level. The domain is hosted on infrastructure identified as CWI in Amsterdam, The Netherlands, and the web server is reported as nginx.

From a domain-health perspective, cwi.nl appears highly established, with a creation date in 1986 and nameservers associated with Dutch academic and research infrastructure. No immediate technical security concerns were indicated in the provided scan data.
