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 11:14, www.kontum.udn.vn has a security score of 72.6/100 (grade C – “Fair”). CyStack’s automated assessment recorded 13 issues to review after completing 94.5% of applicable checks. The website owner should address “Database or cache exposed to the Internet” first, then review the remaining items in order of impact.
At assessment time, CyStack did not find www.kontum.udn.vn or related infrastructure on any scam, phishing, or malware warning list after checking 4 online reputation sources. This result reflects external observations; it does not guarantee absolute safety or verify the organization’s legal status or reputation.
No exposure record was found for an email address ending in @udn.vn in the available data. This does not guarantee that an exposure has never occurred.
Frequently asked questions
A valid SSL certificate still does not prove that www.kontum.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.
www.kontum.udn.vn used a valid SSL certificate at assessment time, valid until January 21, 2027. This status may change when the certificate expires or the server configuration changes.
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.kontum.udn.vn.
Why it matters
Databases and caches often contain sensitive information and are normally used only by internal applications. Direct Internet access makes password attacks and configuration mistakes much more likely to become a data breach.
What to do
Listen only on private interfaces, allow connections only from required application systems, and require strong authentication and encryption.
Evidence and check scope
Why it matters
Content Security Policy (CSP) limits where scripts, styles, frames, and other browser content may come from. A strong policy reduces the impact if an attacker manages to inject content into a page.
What to do
Define only the sources the application needs, test the policy before activating it, and avoid broad wildcard (*) rules, unsafe-inline, and unsafe-eval where possible.
Why it matters
TLS 1.0 and TLS 1.1 use outdated security designs and are no longer accepted by modern standards. Leaving them enabled allows older, weaker connection methods.
What to do
Disable TLS 1.0 and TLS 1.1, support TLS 1.2 securely, and enable TLS 1.3 where possible.

This is a quick, point-in-time check from outside the organization. It can surface visible risks, but it does not replace penetration testing or an authenticated assessment.
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.
Review exposed email recordsThe assessment identified 3 technologies on www.kontum.udn.vn. Only 3 had a version reliable enough for accurate CVE matching.
Review technologies and CVEsThe assessment observed 1 public IPs and 3 open ports for www.kontum.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 541+ 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 subdomainsScope of this check
This check only evaluates the homepage response and content that the scanner could reach. Other pages and sign-in flows may use different settings.
