nsf.gov Overview

Description of nsf.gov

nsf.gov appears to be the official website of the U.S. National Science Foundation, an independent federal agency that supports science and engineering research, education, and funding programs across the United States. The page title, metadata, and homepage layout indicate that the site provides information about grants, proposal submissions, awards, agency policies, focus areas, and public news related to federally supported research.

Based on the domain, government branding, and page content, the site appears to serve researchers, universities, educators, students, policymakers, and the general public seeking information about NSF programs and funding opportunities. Multiple web-classification sources categorize it as a government and education resource, which is consistent with the visible content and the long-established .gov domain.

Safety Assessment for nsf.gov

The available scan results are broadly reassuring. At the time of this scan, 0 out of 91 security engines detected malicious activity, and the checked threat databases did not report the domain on phishing or malware-related blacklists. The domain is also long-established, has a strong traffic presence, and the visible content matches what would be expected from an official U.S. government science agency.

One automated malware scan did label a single page fragment as suspicious, but no malware family was identified, no external links or referenced domains were flagged, and this appears to be an isolated heuristic finding rather than a corroborated threat signal. With no multi-engine detections and clean blacklist results, that single generic alert carries limited weight.

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

Technical Description

The site uses a valid SSL/TLS certificate issued by DigiCert with an expiry in January 2027, which supports encrypted connections for visitors. DNSSEC is enabled and signed, which may help protect against certain forms of DNS tampering. The domain has been registered since 1997 through get.gov, uses NSF-controlled nameservers, and is hosted on infrastructure identified as National Science Foundation in Alexandria, United States.

The web server appears to be Apache, and the scan data does not indicate notable infrastructure-level security issues. The only minor concern in the provided results is a single generic heuristic flag from one malware scan on an award search URL fragment, but there is no broader evidence of compromise based on the available scan data.
