Risk signals

Risk signals None found

Nothing stood out. That is not a guarantee of safety — only public information was examined.

Domain age 29 years (1996-12-29 registered)

The domain has been maintained for a long time.

Certificate issued 331 days ago

Certificates are renewed regularly, so a recent date on its own is normal.

Signs of real operation mail configured · SPF present

Mail is properly configured too — not something hastily built sites usually bother with.

Who serves this site

DNS provider Kakao

DNS records are managed here — this is where you log in to add or change them.

ns1.kakao.com · ns2.kakao.com
CDN / edge Could not determine

Requests pass through this layer before reaching the real server. It also hides the origin from visitors.

Origin host (estimated) 121.53.93.60

Estimated from the IP registration. A CDN in front makes the true origin invisible from outside, which is the safer arrangement.

IP 121.53.93.60 · 211.242.11.41
Mail provider Kakao

This service handles mail for the domain. Follow its documentation when setting SPF and DMARC.

Certificate & encryption

Certificate expiry 62 days left (2026-09-30)

Plenty of validity left.

Issued by DigiCert Inc
Certificate coverage *.kakao.com, kakao.com

This domain is covered by the certificate.

Legacy TLS TLS 1.0/1.1 disabled

Obsolete protocol versions are switched off.

Email security (anti-spoofing)

SPF Configured · DNS lookups 2/10 max

A sender policy is published and closed off correctly.

v=spf1 ip4:103.246.58.76 ip4:103.246.58.77 ip4:103.246.58.78 ip4:103.246.58.79 ip4:103.24…
DMARC p=none

The policy only monitors — spoofed mail is still delivered.

v=DMARC1; p=none; rua=mailto:[email protected]
How to fix
Watch the reports for a few days, then raise the policy to p=quarantine.
DKIM Found: google

Outgoing mail is signed, so recipients can verify it was not forged.

Mail servers (MX) 10 mx1.kakao.com. · 10 mx4.kakao.com. · 10 mx3.kakao.com.

These servers receive mail for the domain.

MTA-STS Not enabled

Most mail is still encrypted without it, but nothing enforces it. Optional.

TLS-RPT Not enabled

There is no channel to report failed mail encryption. Optional.

Mail transport encryption (STARTTLS) Supported (mx1.kakao.com)

Mail to this domain travels over an encrypted channel. Verified by connecting to the actual server.

DNS configuration

CAA Not set

Any certificate authority in the world may issue a certificate for this name.

How to fix
Add a CAA record, for example: 0 issue "letsencrypt.org"
DNSSEC Not enabled

DNS answers cannot be verified against tampering. Not mandatory, but worth enabling.

How to fix
Most registrars enable DNSSEC with a single switch.
DNS propagation Consistent worldwide

All four resolvers queried return the same address.

HTTP security headers

HSTS Configured

Browsers are told to use HTTPS only.

CSP Not set

No policy limits which scripts may run, which is the main defence against XSS.

How to fix
add_header Content-Security-Policy "default-src 'self'" always;
MIME sniffing protection Not set

Browsers may guess file types and execute something unintended.

How to fix
add_header X-Content-Type-Options "nosniff" always;
Clickjacking protection Not set

Another site can frame your pages and trick users into clicking.

How to fix
add_header X-Frame-Options "SAMEORIGIN" always;
Referrer policy Not set

Full URLs may leak to other sites when visitors click away.

How to fix
add_header Referrer-Policy "strict-origin-when-cross-origin" always;
Server version disclosure Hidden

Response time 27ms

The first byte arrives quickly.

Public files & access

robots.txt information leak Disallow 2건 · no sensitive paths

No sensitive-looking paths are listed.

Search engines have to discover pages by following links.

How to fix
Publish sitemap.xml and reference it from robots.txt with a Sitemap: line.

The site still answers over unencrypted HTTP.

How to fix
Return a 301 redirect from port 80 to the https address.
