Rehber

Why this hub matters

Security, SEO and performance can no longer be managed as separate concerns. Weak TLS lowers trust, missing DMARC exposes brand reputation, bad canonicals reduce visibility and slow pages hurt conversion. These tools make the first control layer fast and understandable.

Do I need an account to use the free tools?

No. You can use the tools without creating an account. A professional assessment, report delivery and tracking panel require an account.

Do these tools replace a penetration test?

No. They are designed for first checks and visible signals. Authorized, evidence-led assessment requires a scoped security package.

Which tool should I use first?

Start with the website security scanner, then use SSL/TLS checker for certificates and DNS/email security for SPF, DKIM and DMARC.

Does VefaSec store my results?

Free tool screens show quick results for review. Report delivery is created only when you start a professional panel workflow.
