Security, SEO, and performance checks in one public website report

A useful website scan should not stop at a single score. Fixnx connects public security evidence, crawlability signals, and page experience issues so teams can understand what is visible, what is risky, and what should be fixed first.

Public security posture

Review the visible website surface that attackers and customers can reach first: HTTPS behavior, security headers, cookies, exposed files, forms, login routes, API clues, and unsafe browser behavior.

HTTPS and redirectsHeaders and cookiesExposed filesForms and APIs

SEO crawl foundations

Check the basics Google needs to understand a public page: indexable content, titles, descriptions, canonical signals, robots hints, headings, internal links, image alt text, and structured data signals.

Titles and metadataCanonical and robotsHeadingsInternal links

Performance and page experience

Find practical speed and page quality signals before a launch: heavy assets, render-blocking resources, image handling, page weight, and browser work that can affect user experience.

How Fixnx Works

Public website checks, readable evidence, and a clear fix order

Fixnx is built for site owners, agencies, developers, SaaS teams, and security teams that need a practical security report without setting up a complex testing lab.

Step 1

Enter a public website URL and choose the scan depth that matches the job.

Step 2

Fixnx performs bounded, defensive checks across public pages, headers, cookies, files, forms, APIs, SEO, and performance signals.

Step 3

Findings are grouped by severity, confidence, category, and evidence so the most important work is visible first.

Step 4

The report explains why each issue matters, how to fix it, and what should be retested after deployment.

Launch Checklist

When should you run a website security scan?

Run a scan when public website behavior changes: a new landing page, CMS update, plugin change, login flow, checkout route, API release, CDN migration, domain change, or customer-facing campaign.

Read website security checklist
  1. Priority 1

    Run a public scan before launch, after DNS/CDN changes, and after adding forms, login pages, checkout, or account areas.

  2. Priority 2

    Fix confirmed security issues first, especially data exposure, authentication, authorization, exposed files, and dangerous redirect or injection evidence.

  3. Priority 3

    Use SEO findings to make pages crawlable and understandable with descriptive titles, headings, links, canonical tags, and structured content.

  4. Priority 4

    Use performance findings to reduce friction for real users, especially page weight, heavy images, render blockers, and layout stability issues.

Example Report Finding

What a Fixnx report makes clear

The report separates evidence from advice. Each finding shows what was observed, why it matters, and what to fix first.

Issue: Missing Content-Security-Policy

Risk: Medium

Evidence: Header not found on tested pages

Recommended fix: Start with report-only CSP, review violations, then enforce a tested policy.

PRODUCT

01

Website Vulnerability Scanner

Find the website risks that are easiest to miss when a site moves fast: unsafe headers, exposed files, injection signals, auth weaknesses, and public attack surface.

A useful vulnerability scanner should do more than list warnings. Fixnx turns public website checks into a readable security report with evidence, priority, and next steps your team can act on.

Run a fast website vulnerability scanner for public security risks, exposed files, risky headers, authentication issues, and clear remediation guidance.

Why website vulnerability scanning should be part of every release

Most website incidents start with small public mistakes: a forgotten backup file, a weak login route, a missing browser protection, or an API endpoint that reveals more than expected. A scan gives teams a practical way to see those problems before users or attackers do.

Fixnx is designed for fast feedback. It separates confirmed issues from likely signals, explains evidence clearly, and keeps low-impact hardening items from drowning out the risks that should be fixed first.

Use this page as a launch point before a release, after a major frontend change, or whenever a new domain becomes public.

Article FAQ

Is a website vulnerability scanner the same as a penetration test?

No. A scanner gives fast, repeatable coverage for common public risks. A manual penetration test adds deeper business logic testing and human validation.

Can I scan a live production website?

Yes. Fixnx uses bounded checks designed for live websites. Deep or authenticated scans should still be scoped carefully.

02

Web Security Scanner

Scan the browser-facing parts of your website and understand which weaknesses matter before they become support tickets or security incidents.

Modern web apps combine static assets, APIs, sessions, redirects, and third-party scripts. Fixnx reviews the visible web surface and turns technical signals into practical recommendations.

Use Fixnx as a web security scanner for headers, browser protections, authentication surface, exposed resources, and actionable website security reports.

What a web security scanner should explain

A good web security scanner should tell a story: what was tested, what was proven, what is only suspicious, and what should happen next. Without that structure, teams waste time arguing about noisy results.

Fixnx keeps the report focused on concrete risk. Confirmed vulnerabilities are separated from likely findings and informational coverage notes, so teams can fix the highest-impact issues first.

Run a scan when new pages, APIs, authentication changes, or third-party scripts are deployed.

Article FAQ

What does a web security scanner check first?

It starts with public pages, browser behavior, headers, forms, exposed files, and discovered API routes.

Why do some findings stay likely instead of confirmed?

Fixnx only marks exploitability as confirmed when the scan collected proof. Strong signals without proof stay likely.

PRODUCT

03

API Security Scanner

Find API routes that expose sensitive data, accept risky input, or behave differently across anonymous and authenticated contexts.

APIs are often shipped faster than documentation. Fixnx discovers routes from browser traffic, links, JavaScript, and common paths, then classifies what each endpoint appears to handle.

Go to article

Best for

  • REST APIs
  • SaaS APIs
  • Internal dashboards
  • SPA backends

Outcomes

  • See discovered API surface
  • Identify sensitive endpoints
  • Separate public from protected routes
  • Improve API hardening
Endpoint discoverySensitive route classificationAuth surfaceID parametersCORS behaviorResponse evidence

Discover API endpoints, classify sensitive routes, test common API risks, and produce clear evidence for public and authenticated API security issues.

API security starts with knowing what is reachable

Many API risks are not hidden in complex exploits. They come from endpoints that were meant to be internal, debug routes left exposed, or user-owned resources that do not enforce authorization consistently.

Fixnx helps by showing the discovered API surface, classifying endpoint purpose, and attaching evidence to high-risk findings. That makes it easier to talk about API security with developers and product owners.

Use API scanning after frontend releases, backend route changes, and authentication refactors.

Article FAQ

Does Fixnx discover API endpoints automatically?

Yes. It samples browser traffic, page links, forms, JavaScript hints, and common API paths within scope.

Can API authorization be fully proven without login contexts?

No. Full cross-user proof needs separate user contexts, such as userA and userB sessions.

PRODUCT

04

Attack Surface Scanner

Understand what your website exposes to an outside visitor: pages, APIs, parameters, headers, sensitive files, and high-value routes.

Attack surface is the security inventory attackers see first. Fixnx turns that inventory into a report that shows coverage depth and risk priority.

Crawled pagesDiscovered endpointsForms and inputsSensitive filesAdmin-like pathsTechnology hints

Map public pages, APIs, forms, sensitive endpoints, headers, JavaScript assets, and likely security risks with a fast attack surface scanner.

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.

Article 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.

PRODUCT

05

Security Headers Scanner

Check whether your website sends the browser security headers that reduce clickjacking, MIME sniffing, downgrade, and data leakage risk.

Security headers are not a substitute for secure code, but they are a strong baseline. Fixnx reports missing and weak headers without letting header-only issues outrank confirmed exploitable vulnerabilities.

HSTSContent Security PolicyX-Frame-OptionsX-Content-Type-OptionsReferrer-PolicyPermissions-Policy

Check HSTS, CSP, X-Frame-Options, Referrer-Policy, Permissions-Policy, content type protection, and other browser security headers.

Security headers are a baseline, not the whole story

Headers help browsers enforce safer behavior, but a missing header should not be treated the same as confirmed SQL injection or authentication bypass. Priority matters.

Fixnx checks the common browser protections and explains what they do in plain language. The report keeps hardening recommendations useful while still prioritizing higher-impact vulnerabilities.

Use this page when you want a quick header review before sending a site to customers or auditors.

Article FAQ

Which security header matters most?

It depends on the app. HSTS and CSP are often important, but the right priority depends on exposure and confirmed risks.

Can headers fix vulnerable application code?

No. Headers reduce browser-side risk, but server-side vulnerabilities still need code and configuration fixes.

Fixnx keeps the first report readable. It shows what passed, what failed, and what needs more proof before being treated as confirmed.

Run a free check whenever you launch a new site, change hosting, or connect a new domain.

Article FAQ

What does the free website security check include?

It includes public website checks across security, SEO, and performance with bounded scan depth.

Do I need to install anything?

No. Enter a website URL and Fixnx runs the check from outside the site.

InjectionXSSAccess controlAuthenticationSecurity misconfigurationSensitive exposure

Scan a website for OWASP Top 10 risk areas including injection, XSS, access control, authentication, misconfiguration, and sensitive exposure.

Using OWASP Top 10 as a practical checklist

OWASP is useful because it gives teams a shared language. But checklists become noisy when every item looks equally urgent.

Fixnx keeps the OWASP-style view practical by showing severity, confidence, evidence, and recommended first fixes. That helps teams move from awareness to action.

Use this scanner to create a security baseline before deeper manual testing.

Article FAQ

Does this replace an OWASP manual review?

No. It gives fast coverage for common risk areas and helps decide where manual review should focus.

Are all OWASP categories actively exploited by the scanner?

No. Some checks are active, while others are coverage notes or likely signals depending on available proof.

SQL Injection Scanner

Check whether search, filter, login, and ID parameters behave like backend queries can be manipulated.

SQL injection remains one of the clearest signs that application input is reaching a database unsafely. Fixnx looks for measurable response changes and reports evidence carefully.

Go to article

Best for

  • Search endpoints
  • Login routes
  • Filter parameters
  • Legacy apps

Outcomes

  • Find injection candidates
  • See payload evidence
  • Prioritize confirmed findings
  • Add regression tests
Baseline responsePayload responseRecord count differencesSQL error signalsBoolean behaviorSafe limits

Test public parameters for SQL injection signals with baseline comparisons, payload evidence, response differences, and clear confidence labels.

SQL injection proof should be measurable

A scanner should not call SQL injection confirmed because a page looks suspicious. It should show what changed: status, response shape, record count, timing, or error behavior.

Fixnx reports SQL injection with evidence summaries and keeps weaker signals marked as likely. That helps developers reproduce the issue without overstating proof.

Use this check especially on search, login, and API filter routes.

Article FAQ

What makes SQL injection confirmed?

Confirmed SQL injection requires measurable proof such as stable response differences, query errors, record expansion, or verified blind behavior.

Are the payloads destructive?

No. Fixnx uses bounded, controlled payloads intended for safe validation.

Questions about Fixnx website scans

Fixnx reviews the public parts of a website across security, SEO, and performance. It checks headers, exposed files, cookies, forms, login surfaces, APIs, metadata, page structure, browser behavior, and practical signals that help teams understand what to fix first.

Fixnx includes one website scan for free. You can start the scan quickly, then sign in with Google to keep the scan connected to your account and view the full report with the fix guidance.

After signing in, Fixnx unlocks the full report experience: remediation guidance, exact locations, evidence details, saved scan history, and clearer next steps for developers, site owners, agencies, and security teams.

After the free scan, you can buy more scans for a small payment. The current starter pack adds 20 scans for $9.99, which keeps Fixnx accessible while still giving you a report that can often save many hours of manual review and help avoid issues that may cost thousands later.

A strong Fixnx score means the visible website baseline looks healthy for the scan mode, with no serious confirmed public evidence found during the scan. It gives you a clear confidence signal and helps you focus attention where improvement would have the most value.

Fixnx prioritizes findings by evidence, exploitability, login impact, sensitive data exposure, access control risk, CMS exposure, browser hardening, SEO, and performance. The goal is to show the most useful fixes first instead of overwhelming you with generic warnings.

Yes. Fixnx is especially useful for sites that rely on CMS platforms, public login pages, plugins, themes, forms, uploads, and common web hosting stacks. It highlights practical hardening gaps and turns them into clear actions.

A launch often exposes new pages, scripts, forms, redirects, tracking tags, and performance changes. Fixnx helps catch visible risks before customers, search engines, or attackers find them first.

Yes. Fixnx keeps Security as the main signal, but it also reviews SEO and performance basics such as metadata, crawl signals, page weight, speed hints, and content structure so the report supports both protection and growth.

Start with confirmed exploitable security findings, then high-impact login, data exposure, access control, CMS, and browser hardening issues. After that, use the SEO and performance findings to improve crawl quality, speed, and user experience.

Yes. Fixnx reports are written to be practical: each issue includes context, priority, evidence, and fix guidance so technical and non-technical stakeholders can understand what changed and why it matters.
