Updated at The higher the score, the more externally observable protections the system has recorded. This page does not certify that the website is reputable, legitimate, or completely free of vulnerabilities.
As of September 12, 2026 at 03:18, www.smp.udn.vn has a security score of 93/100 (grade U – “Unrated”), but this result is provisional because some required evidence is incomplete. CyStack’s automated assessment recorded 4 issues to review after completing 49.3% of applicable checks. The website owner should address “Email spoofing protection (DMARC)” first, then review the remaining items in order of impact.
At assessment time, CyStack did not find www.smp.udn.vn or related infrastructure on any scam, phishing, or malware warning list after checking 5 online reputation sources. This result reflects external observations; it does not guarantee absolute safety or verify the organization’s legal status or reputation.

Frequently asked questions
A valid SSL certificate still does not prove that www.smp.udn.vn is safe, legitimate, or free of scam signals. For a more complete assessment, this report also checks phishing and malware, exposed email records, IPs and open ports, subdomains, technologies, and CVEs that may apply to observed versions.
HTTPS on www.smp.udn.vn could not be reached during this assessment, so its SSL certificate and transport encryption could not be evaluated.
Review HTTPS and certificateData sources
CyStack compiles scan results from its internal cybersecurity monitoring systems, including CyStack VulnScan and CyStack Threat Intelligence, together with publicly available Internet data. The assessment only observes and analyzes information already available; it does not attempt unauthorized access, test passwords, send exploit code, or change or disrupt the assessed system.
CyStack VulnScan continuously discovers assets, validates vulnerabilities, and helps security teams prioritize remediation across the enterprise.
These 3 failed checks or warnings have the greatest impact on the result for www.smp.udn.vn.
Why it matters
DMARC lets the domain owner tell receiving services what to do when the visible From address is not verified by SPF or DKIM. Without DMARC, attackers have more opportunity to impersonate the domain in phishing email.
What to do
Publish a DMARC record at _dmarc, begin by collecting reports, and confirm that legitimate senders pass before applying a blocking policy.

Why it matters
Names containing admin, development, staging, VPN, database, or monitoring terms may point attackers toward valuable systems. A name alone does not prove exposure, but it identifies a surface that should be reviewed.
What to do
Remove obsolete DNS names and protect non-public systems with strong authentication, MFA, network allowlists, or a VPN.
Why it matters
Certificate Authority Authorization (CAA) records state which certificate providers may issue certificates for the domain. This reduces the chance of an unintended provider issuing one.
What to do
Publish CAA records that allow only the certificate providers your organization actually uses.
Evidence and check scope
Each public IP is grouped with its open services, identified products and any CVEs that may apply to the observed version.
64.46.118.18vss-502-ams01.hawkhost.comNo open service was observed on this address in the ports checked.
No record associated with an @udn.vn email address was found in the currently available data. This does not rule out incidents that have not been observed.
No technology could be identified with enough confidence on www.smp.udn.vn to run version-based CVE matching.
Review technologies and CVEsThe assessment observed 1 public IPs and 0 open ports for www.smp.udn.vn. An open port is not the same as a vulnerability, but the website owner should keep every public service updated and appropriately restrict access.
Review IPs and open portsThe assessment observed 523+ public subdomains of udn.vn. This list can reveal additional entry points such as APIs, administration systems, or test environments, but it does not mean that every subdomain is risky.
Review discovered subdomainsDiagnostic information
Subdomain discovery did not complete, so the current list may be incomplete.
