Burp Suite and SiteSecurityScore do two different jobs
Burp Suite from PortSwigger is a toolkit for manual web application penetration testing. Pentesters route their browser through its intercepting proxy, replay and tamper with requests in Repeater, craft custom fuzzing attacks with Intruder, and extend it with add-ons. The free Community edition is limited to the proxy and Repeater, the paid Professional license adds the scanner and full Intruder, and Enterprise is a separate automated DAST product. It is a manual driven tool aimed at testing injection, authentication, and business logic flaws, and it carries a learning curve.
The trade off is that Burp Suite is a desktop, manual heavy tool. You install it, configure a proxy and browser certificate, learn the interface, and drive the testing yourself. That is the right fit for a full time pentester running a focused engagement. It is overkill when you simply want to know whether your site is missing Content Security Policy, sending cookies without the Secure flag, or running an HSTS header that is too weak. SiteSecurityScore owns that job. It is the essential automated layer anyone can run, an instant, zero setup audit that grades the header, TLS, DNS, cookie, CSP, CORS, and security.txt layer and hands you copy and paste fixes in seconds. Run it in your browser with no install and no account, then let free continuous daily monitoring keep watching your site and email you the moment anything changes.
Burp Suite vs SiteSecurityScore: side by side feature comparison
These tools overlap less than you might expect. Burp focuses on manual testing. SiteSecurityScore delivers everything you need for the configuration layer in one scan and adds free continuous monitoring on top. The table below uses a manual tag where Burp can surface something only through hands-on work rather than an automatic report.

What Burp Suite is built for, and where SiteSecurityScore fits
The cleanest way to think about it is two columns. Burp lives in the manual testing column. SiteSecurityScore owns the configuration layer column, the layer attackers probe first, and grades it automatically the instant you enter a URL. Most teams need both at different moments.
What Burp Suite covers
- Intercepting proxy to inspect and tamper with every request and response.
- Repeater to craft and replay individual requests when probing a flaw.
- Intruder for custom fuzzing and brute force style automated attacks.
- Deep extension ecosystem and a scanner in the Professional license.
Where SiteSecurityScore shines
- Instant passive audit with no install, proxy, or browser certificate setup.
- Automatic grading of CSP, HSTS, and the full set of security headers.
- TLS, DNS records, cookies, CORS, and security.txt covered in one scan.
- Continuous daily monitoring with email alerts on any configuration change.
Security headers analysis
CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, COOP, COEP, and CORP, graded automatically with no manual proxy work.
DNS security records
SPF, DKIM, DMARC, and CAA analysis. Find gaps in your email authentication, the kind of layer a manual web pentest rarely touches.
Cookie security audit
HttpOnly, Secure, SameSite, Path, Domain, and prefix checks for every cookie, reported instantly rather than inspected request by request.
Deep CSP analysis
Directive by directive breakdown of your Content Security Policy. Identifies unsafe-inline, overly broad wildcards, and missing directives.
TLS and certificate review
Protocol versions, certificate validity, and chain checks, plus mixed content detection, all without leaving the browser.
security.txt validation
Verifies the presence and correctness of your security.txt file so researchers can reach you through the proper disclosure channel.
Continuous website security monitoring with email alerts
A Burp Suite session is a point in time engagement. You run your manual tests, write up the findings, and close the project. If a header is dropped in a deploy next week or your certificate drifts toward expiry, nothing tells you until someone sits down and tests again.
SiteSecurityScore gives you free continuous monitoring that runs daily automated scans of your HTTP security headers, Content Security Policy, TLS certificates, DNS records (SPF, DKIM, DMARC), and cookie security in a single pass. When anything changes, you receive an email alert immediately. No manual re-testing and no desktop toolkit 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 security 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 hands you free generator tools that produce ready to ship, copy and paste configurations for your web server, something a manual testing toolkit leaves to you.
Scan authenticated pages without proxy setup
Chrome Extension
Reaching pages behind a login in Burp means routing your browser through its proxy and trusting its certificate. The SiteSecurityScore Chrome extension captures real response headers from your authenticated sessions with one click. Grade admin panels, internal dashboards, and staging environments in seconds with no proxy and no certificate setup at all.
Run a free website security scan
Enter any URL and get a complete configuration audit covering HTTP headers, CSP, HSTS, TLS certificates, DNS records, and cookie security, graded with copy and paste fixes in seconds. No install and no account required.
Start scanningFrequently asked questions
Is SiteSecurityScore a replacement for Burp Suite?
SiteSecurityScore and Burp Suite serve different needs and work well together. Burp Suite is a desktop toolkit for hands-on manual penetration testing with an intercepting proxy, repeater, intruder, and scanner. SiteSecurityScore is the fastest way to grade and fix the configuration layer of your site, the layer attackers probe first, covering HTTP security headers (CSP, HSTS, X-Frame-Options), deep CSP analysis, TLS, DNS records (SPF, DKIM, DMARC), cookies, CORS, and security.txt, with free continuous daily monitoring. If you want an instant, zero setup grade of your header and TLS posture with copy and paste fixes in seconds, SiteSecurityScore is the Burp Suite alternative online to reach for. For deep manual testing, the two are complementary.
What does SiteSecurityScore do that Burp Suite does not?
SiteSecurityScore runs an instant passive audit with no install or proxy configuration, gives you a letter grade and copy-paste fixes, and offers continuous daily monitoring with email alerts when a header is removed or a certificate is about to expire. It checks DNS email authentication (SPF, DKIM, DMARC, CAA), security.txt, and cookie attributes out of the box and ships free generator tools for CSP, HSTS, Permissions-Policy, and CORS. Burp Suite is a manual testing platform and does not provide hosted continuous header monitoring.
Is Burp Suite free, and how is it different from an online scanner?
Burp Suite Community Edition is free but limited. It includes the intercepting proxy and repeater but holds back the automated vulnerability scanner and the full Intruder. Professional is a paid annual per user license, and Enterprise is a separate automated DAST product. All editions are desktop, manual heavy tools with a learning curve. SiteSecurityScore needs no install and no account, runs in seconds from the browser, and grades the header, deep CSP, TLS, DNS, cookie, CORS, and security.txt configuration layer with copy and paste fixes, plus free continuous daily monitoring, a REST API, and a Chrome extension for authenticated pages.
Can I monitor my security headers and TLS automatically without Burp Suite?
Yes. SiteSecurityScore runs automated daily scans of your HTTP security headers, Content Security Policy, TLS certificate, DNS records, and cookies in one pass. You get an email alert when anything changes, such as a removed header, a weakened CSP, or a certificate nearing expiration. Burp Suite Professional is a manual desktop toolkit and does not provide managed continuous monitoring of this kind.
Is there a free Burp Suite alternative online for checking my website?
Yes. SiteSecurityScore runs free online scans covering HTTP security headers, deep CSP analysis, TLS certificates, DNS records, cookies, CORS, and security.txt with no account required. It is the Burp Suite alternative online for developers and site owners who want an instant, accurate configuration grade with copy and paste fixes in seconds. Free continuous daily monitoring with email alerts, a REST API, a Chrome extension for authenticated pages, free header generator tools, and an MCP connector for Claude Code and ChatGPT Codex are all built in, and paid plans add PDF reports and higher scan limits.
Should pentesters use SiteSecurityScore or Burp Suite?
Full time pentesters will still want Burp Suite for deep manual testing of injection, authentication, and business logic flaws. SiteSecurityScore is the essential automated layer that anyone can run, developers, DevOps teams, and site owners who want an instant, accurate grade of their header, deep CSP, TLS, DNS, cookie, CORS, and security.txt configuration with copy and paste fixes in seconds. Many teams lean on SiteSecurityScore for free continuous configuration monitoring and reach for Burp during a focused manual engagement.
Can SiteSecurityScore scan pages behind a login?
Yes. SiteSecurityScore ships a Chrome extension that captures real HTTP response headers from your authenticated sessions in one click, so you can grade admin panels, internal dashboards, and staging environments in seconds. You get a full header and cookie grade on protected pages with no proxy and no browser certificate setup of the kind Burp Suite requires.
