Grade and fix your configuration layer in seconds, for free
Invicti, which was previously called Netsparker, is a paid enterprise dynamic application security testing platform. It crawls your application, probes for injection and runtime flaws, and uses proof based scanning to confirm many findings before they reach your team. It runs on-prem or in the cloud and is aimed at security teams testing large portfolios of apps and APIs. That depth is its focus, and it carries an enterprise license and setup cost to match.
A full DAST run takes time to set up and sits behind a paid enterprise license. Meanwhile, a large share of real exposure lives one layer up from the application logic, in the configuration that attackers probe first. A site can have clean application code and still ship without a Content Security Policy, miss HSTS, serve cookies without Secure or HttpOnly flags, lack DNS email authentication records, or expose server details it should not. SiteSecurityScore is the essential layer you should not skip. It grades that configuration posture instantly and for free and hands you copy and paste fixes in seconds, so you lock down the configuration layer today and add a full DAST like Invicti on top when you need deep application coverage.

Everything you need for the configuration layer in one free scan
Security headers analysis
CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, COOP, COEP, and CORP. These headers blunt XSS, clickjacking, and data leakage, and SiteSecurityScore grades every one for free.
TLS and certificate review
Protocol versions, certificate validity and chain, and configuration issues. Catch weak setups and expiring certificates instantly, with the fix spelled out for you.
DNS security records
SPF, DKIM, DMARC, and CAA record analysis. Close gaps in email authentication before attackers abuse them for phishing.
Cookie security audit
HttpOnly, Secure, SameSite, Path, Domain, and prefix checks for every cookie. Catch session hijacking and CSRF risks at a glance.
Deep CSP analysis
Directive-by-directive breakdown of your Content Security Policy. Flags unsafe-inline, broad wildcards, and missing directives, with a generator to fix them.
Disclosure and content checks
CORS configuration, security.txt validation, information disclosure, and mixed content. SiteSecurityScore surfaces the quiet misconfigurations clearly, front and center, instead of buried in DAST noise.
Continuous website security monitoring with email alerts
A configuration change can slip in between full DAST runs. Enterprise scans are scheduled and resource heavy, so a header that gets removed or a CSP that loosens on a Tuesday deploy might go unnoticed until the next scan window.
SiteSecurityScore includes free continuous daily monitoring that scans your HTTP security headers, Content Security Policy, TLS/SSL configuration, DNS records, and cookie security in a single automated pass. The moment anything changes, you get an email alert. It also supports CSP violation and NEL reporting so you can watch what real browsers are blocking. No scan windows, no seats to buy, and no manual re-testing required.
Automated daily scans
Every monitored site is scanned once per day covering headers, CSP, TLS, DNS, and cookies.
Email alerts on changes
Get notified when your posture changes, a certificate nears expiration, or a header is removed.
Free security header generator tools
Knowing which headers are missing is only half the job. You also need correct values. SiteSecurityScore includes a full suite of free generator tools that produce production ready, copy and paste configurations for your web server in seconds.
Check authenticated pages without an authenticated scan profile
Chrome Extension
Setting up authenticated scans in a full DAST platform takes configuration and time. The SiteSecurityScore Chrome extension captures real response headers straight from your logged-in sessions, so you can grade admin panels, internal dashboards, and staging environments for header and cookie issues with one click. No scan profiles, no waiting.
Run a free website security scan
Enter any URL and get a complete configuration audit covering HTTP headers, deep CSP, HSTS, TLS certificates, DNS records, and cookie security, with a letter grade and copy and paste fixes in seconds. No license, no sales call, no account required.
Start scanningFrequently asked questions
Is SiteSecurityScore a replacement for Invicti (formerly Netsparker)?
SiteSecurityScore and Invicti work on different layers. Invicti is a paid enterprise DAST platform, formerly Netsparker, that crawls your application, tests for injection and runtime flaws, and uses proof based scanning to confirm findings. SiteSecurityScore is the fastest way to grade and fix the configuration layer that attackers probe first, covering HTTP security headers, deep Content Security Policy analysis, TLS, DNS records, cookies, CORS, and security.txt. It is free, instant, and purpose built for the posture you should never ship without. Run SiteSecurityScore to lock down your configuration layer in seconds, then add a full DAST when you want deep application testing on top.
What does SiteSecurityScore check that a quick scan covers without an Invicti license?
SiteSecurityScore gives you everything you need for the configuration layer in one scan. It checks HTTP security headers (Content Security Policy, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, COOP, COEP, CORP), deep CSP policy analysis, TLS/SSL configuration and certificates, DNS records (SPF, DKIM, DMARC, CAA), cookie security attributes, CORS configuration, security.txt, information disclosure, and mixed content. You get a letter grade with copy and paste fixes instantly and for free, with no enterprise license, no installation, and no account for basic scans.
Is Invicti (Netsparker) free, and how is SiteSecurityScore different on cost?
Invicti is a commercial enterprise platform without a free tier. Pricing is quote based and scales with the number of scan targets and the deployment model, which is aimed at large security teams running DAST across many applications. SiteSecurityScore is free for basic scans with no account required, so you can grade and fix your header, TLS, DNS, cookie, and CSP posture in seconds. No license, no sales call. It is the essential configuration layer you should secure first, whatever you spend on a full platform later.
Can I monitor my security headers and TLS configuration automatically?
Yes. SiteSecurityScore includes free continuous daily monitoring that scans your HTTP security headers, Content Security Policy, TLS/SSL configuration, DNS records, and cookies in one automated pass. You receive email alerts the moment anything changes, such as a removed header, a CSP policy change, or a certificate nearing expiration. It also supports CSP violation and NEL reporting so you can watch real browser activity, all without configuring scan windows or paying for a seat.
Does Invicti cover the same header and CSP configuration details as SiteSecurityScore?
Invicti focuses on dynamic application testing, finding injection flaws, authentication issues, and runtime vulnerabilities, then confirming them with proof based scanning. SiteSecurityScore owns the configuration layer with a directive by directive CSP breakdown, letter grade scoring, and copy and paste fixes for headers, HSTS, Permissions-Policy, and CORS. This is exactly the depth a DAST run does not give you, and SiteSecurityScore delivers it instantly and for free.
Can SiteSecurityScore scan pages behind a login?
Yes. SiteSecurityScore offers a Chrome browser extension that captures real HTTP response headers from your authenticated sessions. This lets you check admin panels, internal dashboards, and staging environments for header and cookie issues with one click, no authenticated scan profiles to configure. It also exposes a REST API and an MCP connector for Claude Code and ChatGPT Codex, so you can grade and fix your posture straight from your own workflows and CI pipelines.
