A passive check of what anyone on the internet can already see: HTTPS, security headers, cookie flags and email spoofing protection. No scanning, no load on your server.

FAQ

About the check.

Is this a penetration test?+

No. It's a passive check of what any browser or mail server can already see: your HTTPS setup, security headers, cookie flags and email DNS records. A penetration test actively looks for exploitable weaknesses with your permission — see our VAPT service.

Will it affect my website?+

No. It makes a couple of normal page requests and DNS lookups — the same as a single visitor. Nothing is stored on our side.

My grade is low. Is my website hacked?+

Not necessarily. Missing headers and email records are very common and are about hardening, not proof of a breach. They make attacks like phishing with your domain, clickjacking or script injection easier, so they're worth fixing.

Can you fix these for me?+

Yes. Most of these fixes take hours, not weeks, and we're engineers as well as security consultants. Send us your result on WhatsApp for a free review.

Talk to a security partner.

One message is enough. You'll speak directly with the engineer who builds your system — and get a fixed quote, not a sales pitch.
