What this page helps you understand
Attack surface is the security inventory attackers see first. Fixnx turns that inventory into a report that shows coverage depth and risk priority.
What this scan checks

Technology hints
A smaller attack surface is easier to defend
Teams cannot protect routes they do not know about. An attack surface scan gives a practical map of the public website and the API signals that appear during rendering.
Fixnx keeps the scan bounded so it is useful during normal work. It reports how many pages, endpoints, parameters, and active probes were covered, which makes the result easier to trust.
Use this scan before a launch, before onboarding a customer, or when you inherit an existing website.
Example Fixnx finding
Issue: Missing browser security header
Risk: Medium
Evidence: A recommended browser protection header was not present on tested responses.
Recommended fix: Add the missing header, test it on staging, deploy, and rescan to confirm the evidence changed.
Browser hardening cannot fix vulnerable code, but it can reduce common attack impact and improve security posture.
What to fix first
- Critical exposed files, admin panels, secrets, or takeover paths.
- Broken HTTPS, missing redirects, weak SSL/TLS behavior, or unsafe cookie handling.
- Confirmed injection, XSS, access-control, authentication, or sensitive API evidence.
- High-impact security headers and browser protections that reduce attack impact.
- Medium and low hardening recommendations after the risky public evidence is fixed.

FAQ
What is attack surface scanning?
It is the process of mapping reachable pages, endpoints, inputs, files, and configuration signals that could be attacked.
Does attack surface scanning prove every vulnerability?
No. It maps exposure and highlights risks. Some findings need active proof or authenticated testing.
What does Attack Surface Scanner check first?
It starts with crawled pages, then reviews discovered endpoints, forms and inputs, and other public signals that can be checked safely from outside the site.
Can I use Attack Surface Scanner on any website?
Only scan websites you own or have explicit permission to test. Fixnx is built for defensive security checks and website protection. Unauthorized scanning may be illegal.
Does Attack Surface Scanner prove a site is completely secure?
No. A scan reports the public evidence it collected during a bounded test. It helps you find visible risk, but it cannot guarantee that every private workflow or server-side issue is safe.
Can Fixnx help me understand how to fix the findings?
Yes. Fixnx reports include evidence, severity, confidence, and remediation guidance so owners, developers, and security teams can decide what to fix first.
