Free Website Security Check - Graded in 60 Seconds
Run a free, read-only security check on your domain. Letter grade across transport, headers, integrity and exposure - with a fix for every finding.
Short answer
A useful free check is passive: it grades what any browser already receives - headers, redirects, TLS signals, public files - without installing an agent. Use it for posture, not as a pentest substitute.
What free should cover
Transport, headers, exposure, obvious integrity issues. No exploit payloads required for that value.
If a free tool needs deep install agents for a first grade, it is selling a different product.
Readers skimming free website security check often stop at definitions. The part that prevents incidents is the verification step after the change - and the habit of re-checking after the next deploy that touches the same layer.
How our grade works
Weighted passive checks map to an A-F band. High-impact misses cost more. Each finding includes a fix path.
Use the letter as prioritization, not a trophy for the homepage.
Common failure mode for free website security check: staging looks fine, production still serves the old config because a CDN, load balancer, or second vhost was never updated. Always verify the hostname customers hit.
What free cannot replace
Authenticated testing, business logic review, and human pentests.
Start free; escalate when the grade plateaus and the business risk still rises.
If this section on free website security check becomes a recurring ticket, automate the check. Manual one-offs rot; a post-deploy assertion or weekly grade keeps the control honest.
What to do this week
- Run the free check on production.
- Fix findings that drop the grade the most first.
- Re-run until the letter moves.
- Save both reports for the evidence folder.
Free grades close configuration debt. Humans find the rest.
