A visitor who types the address without https, or follows an old link, gets the unencrypted site. On public Wi-Fi that page can be read and rewritten in transit.
What to do
Redirect every http:// request to https:// with a 301, then add HSTS.
asset: https://www.mycosmicmontessori.com/
Nothing tells receiving mail servers which hosts may send as @mycosmicmontessori.com, so anyone can. Phishing that impersonates this domain will land in inboxes.
What to do
Publish an SPF TXT record listing your senders and ending in -all.
asset: mycosmicmontessori.com
SPF and DKIM alone do not protect the From: address a person sees. Without DMARC, a spoofed message can pass SPF for some other domain and still display yours.
What to do
Publish `_dmarc.mycosmicmontessori.com TXT "v=DMARC1; p=none; rua=mailto:dmarc@mycosmicmontessori.com"`, review the reports, then move to p=quarantine and p=reject.
asset: mycosmicmontessori.com
Without HSTS the browser will still try http:// first on a fresh visit, which is the window an on-path attacker uses.
What to do
Send `Strict-Transport-Security: max-age=31536000; includeSubDomains` once you are sure everything works over HTTPS.
asset: https://www.mycosmicmontessori.com/
CSP is the main defence that limits what an injected script can do. Without it, any XSS bug is fully exploitable.
What to do
Start with a report-only policy, tighten it against the reports, then enforce.
asset: https://www.mycosmicmontessori.com/
No X-Frame-Options or CSP frame-ancestors directive, so another site can load this page invisibly inside its own and trick users into clicking.
What to do
Send `X-Frame-Options: DENY` or `Content-Security-Policy: frame-ancestors ’none’`.
asset: https://www.mycosmicmontessori.com/
Check it is not an open relay.
What to do
Restrict 25/tcp to a VPN, bastion, or allow-listed source range.
asset: 15.235.147.148:25
Lets browsers guess content types, which turns some upload and text endpoints into script injection points.
What to do
Send `X-Content-Type-Options: nosniff` on every response.
asset: https://www.mycosmicmontessori.com/
Full URLs — including any tokens or IDs in them — are sent to every third party the page links to.
What to do
Send `Referrer-Policy: strict-origin-when-cross-origin`.
asset: https://www.mycosmicmontessori.com/
Answers for this domain are not signed, so a resolver cannot tell a forged response from a real one.
What to do
Enable DNSSEC at your DNS host and publish the DS record at the registrar.
asset: mycosmicmontessori.com
Not urgent, but worth confirming auto-renew is on and the card on file is current.
What to do
Check auto-renew.
asset: mycosmicmontessori.com
Mail to this domain can be downgraded to plaintext by an on-path attacker, because senders have no way to know TLS is required.
What to do
Publish an MTA-STS policy (a TXT record plus a small HTTPS-hosted file).
asset: mycosmicmontessori.com
Any public certificate authority may issue certificates for this domain. CAA lets you name the ones allowed to.
What to do
Add a CAA record naming your CA, e.g. `0 issue "letsencrypt.org"`.
