71/ 100Needs work

On November 3, 2026 the Site Spider crawled 3534 pages and 464 assets of ntcore.io.vn, starting from https://ntcore.io.vn/. It scored 71 out of 100, a result that needs work. 11 of 33 checks found something to fix, led by sitemap coverage (1,979), heavy assets (14), title tags (439); 8 checks passed. Most of the points went to heavy assets (−6), sitemap coverage (−6), title tags (−4.9). 14 checks found something the score does not count, listed as noted. 4 checks were not run because the crawl fetched nothing for them. The list below shows each check's result, the fix plan, when present, explains what to do first, and the security review at the end of the page covers headers, transport, libraries and exposed files.

Security review

Written by gpt-4o-mini from 16 checks over the crawl

The site ntcore.io.vn lacks essential security headers, which could expose visitor information and increase the risk of script exploitation. Immediate actions are recommended to enhance security.

  • 0 high
  • 1 medium
  • 1 low
  • 2 info
  1. 1

    Cookies Missing Protective FlagsMedium

    Why it matters: Cookies without Secure, HttpOnly, and SameSite flags can be vulnerable to attacks.

    Fix: Set the flags for all cookies: `Secure`, `HttpOnly`, and `SameSite=Lax` or `SameSite=Strict` as appropriate.

    Evidence: Cookie flags

  2. 2

    Missing Referrer PolicyLow

    Why it matters: Without a Referrer-Policy, sensitive page information may be sent to third-party sites.

    Fix: Add the header `Referrer-Policy: no-referrer` to all pages.

    Evidence: Referrer policy

  3. 3

    Lack of Permissions PolicyInfo

    Why it matters: The absence of a Permissions-Policy could allow unwanted access to browser features by potentially harmful scripts.

    Fix: Include the header `Permissions-Policy: geo=(), microphone=(), camera=()` to restrict unused features.

    Evidence: Permissions policy

  4. 4

    Sensitive Paths in robots.txtInfo

    Why it matters: The robots.txt exposes private paths, which could attract probing or unauthorized access attempts.

    Fix: Limit access to sensitive paths using proper access control mechanisms, not just robots.txt.

    Evidence: Sensitive paths in robots.txt

What the checks found

  • FoundReferrer policyLow

    104 of 891 HTML pages send referrer-policy. Without a Referrer-Policy the full page address, including any query string, is sent to every site a visitor clicks through to.

  • NoteThird-party scripts

    Scripts run from 3 other domains without Subresource Integrity, so a compromise of any of them changes what runs on this site. (Tag managers and analytics rarely support SRI; a Content-Security-Policy that names these hosts is the usual control.)

    • www.googletagmanager.com (40 script tags)
    • www.google.com (40 script tags)
    • pagead2.googlesyndication.com (40 script tags)
  • NoteSensitive paths in robots.txt

    robots.txt lists 2 paths that look private. robots.txt is public and does not restrict access, so it doubles as a map for anyone probing the site; those paths need real access control.
