What grade are your security headers?
This is only the headers on your homepage. It does not log in, submit forms, or try to break anything. A marketing site with missing headers is usually a hosting fix. A logged-in app with missing headers is a different job.
I read the headers a browser already receives. No exploits, nothing stored unless you send the form.
Also free: full website security scan
Headers plus cookies, mixed content and old JavaScript, still passive.
Questions
Does an A mean my app is secure?
No. Headers are one layer. They do not check logins, passwords, who can read whose records, or payment flows. That is the web application security review.
Will this attack my site?
No. It requests the homepage and reads headers. It does not guess admin URLs, post forms, or send exploit payloads.
How much is a real review?
$2,400 for one web app, $1,200 to start. You get a written report in 48 hours after I have access. Marketing-site header fixes sit on the hosting plan instead, from $99 a month.
