Is the website “nq57.langson.gov.vn” safe?
As of October 24, 2026 at 23:42, nq57.langson.gov.vn has a security score of 79.3/100 (grade U: “Unrated”), but this result is provisional because some required evidence is incomplete. CyStack’s automated assessment recorded 7 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.
Does nq57.langson.gov.vn show known scam, phishing, or malware signals?
At assessment time, CyStack did not find nq57.langson.gov.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
What affects the security of nq57.langson.gov.vn?
A valid SSL certificate still does not prove that nq57.langson.gov.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.
Does nq57.langson.gov.vn use HTTPS, and is its SSL certificate valid?
HTTPS on nq57.langson.gov.vn could not be reached during this assessment, so its SSL certificate and transport encryption could not be evaluated.
Data compiled from CyStack cybersecurity monitoring systems
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.
These 3 failed checks or warnings have the greatest impact on the result for nq57.langson.gov.vn.
Email spoofing protection (DMARC)No DMARC record was found for the registrable email domain.High
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.
Authorized email senders (SPF)No SPF record was found for the registrable email domain.Medium
Why it matters
Sender Policy Framework (SPF) lists the systems allowed to send email for the domain. Without it, receiving services have less evidence to distinguish legitimate mail from spoofed mail.
What to do
Publish one SPF TXT record that includes every legitimate email service and no unauthorized sender.
Potentially sensitive subdomainsCyStack confirmed 156 active DNS subdomains of langson.gov.vn. 1 names may expose sensitive services and should be reviewed.Medium
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.

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.
Have @langson.gov.vn email addresses appeared in exposed data or information-stealer (infostealer) logs?
There are currently 17 exposed email records matching the langson.gov.vn domain. These records may be old or already resolved. The website owner should verify them before resetting passwords or locking related accounts.
Which public IPs, services, and ports does nq57.langson.gov.vn expose?
The assessment observed 1 public IPs and 3 open ports for nq57.langson.gov.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.
How many subdomains of langson.gov.vn have been discovered?
The assessment observed 156 public subdomains of langson.gov.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.
