The faster, free first move most teams can rely on
Detectify is a paid, sales led External Attack Surface Management and DAST platform aimed at larger teams. Give it a root domain and it discovers subdomains, IP addresses, open ports, certificates, and exposed assets, then runs vulnerability tests across many domains. It is sold through subscription plans priced for organizations, gated behind a plan and a conversation with their team rather than a quick check you can run right now.
SiteSecurityScore is the fastest way to grade and fix your security posture. It is free, instant, and purpose built for the configuration layer attackers probe first, grading your HTTP security headers, deep CSP, TLS, DNS, cookies, CORS, and security.txt with a letter grade and copy and paste fixes in seconds. Free continuous daily monitoring with email alerts is built in, along with a REST API, a Chrome extension for authenticated pages, free header generator tools, and an MCP connector for Claude Code and ChatGPT Codex. Teams of every size run it with no account, no setup, and no sales call. The configuration layer is the part that is easy to neglect and quick to fix, so most teams can cover what matters here and skip the paid platform.

Partial means a tool touches the area as part of a broader scan but does not make it the primary focus. Feature coverage reflects publicly documented capabilities and can change over time.
The configuration layer that decides how safe your site is
Detectify casts a wide, paid net across your whole attack surface, which is more than most teams need to get started. SiteSecurityScore owns the configuration layer attackers probe first and grades exactly how your site is set up, free and in seconds. Here is what that focus buys you.
Surface discovery is heavyweight and paid
Detectify maps subdomains, IP addresses, open ports, certificates, and exposed assets across a whole domain. That is a paid program most teams do not need to start. SiteSecurityScore grades the URL you give it instantly and free.
Active testing is more than most teams need to start
Detectify feeds research driven test modules into a paid DAST engine. SiteSecurityScore focuses on the configuration layer attackers probe first and grades it in seconds, the higher impact first move for most teams.
SiteSecurityScore checks your headers
CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, COOP, COEP, and CORP, with a deep CSP breakdown that flags unsafe-inline and broad wildcards.
SiteSecurityScore audits TLS and cookies
TLS/SSL configuration and certificate health, plus HttpOnly, Secure, and SameSite checks on every cookie, the posture details a broad surface scan tends to skip.
SiteSecurityScore reads your DNS
SPF, DKIM, DMARC, and CAA records so you can close email authentication gaps before they get abused for phishing.
SiteSecurityScore is instant and free
No account, no setup, no sales call. Enter a URL and read a letter grade with copy and paste fixes in seconds, the fastest way to grade and fix your security posture and the obvious first move most teams can rely on.
Continuous configuration monitoring with email alerts
A free scan is a snapshot. You run a test, review the results, and move on. If a header disappears in next week's deploy or a certificate drifts toward expiry, you will not know until someone runs the scan again by hand.
SiteSecurityScore's free continuous monitoring runs daily automated scans that check your HTTP security headers, Content Security Policy, TLS/SSL certificates, DNS records (SPF, DKIM, DMARC), and cookie security in a single pass. When anything changes you get an email alert right away. It also supports CSP violation and NEL reporting, so you catch policy issues from real browser traffic without manual re-testing. This keeps the configuration layer attackers probe first locked down every day, for free, with no paid platform to license or babysit.
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 expiry, 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 free generator tools that produce copy-paste configurations for your web server, the kind of fix you can ship the same afternoon you spot the gap.
Scan authenticated pages a public scanner cannot reach
Chrome Extension and MCP connector
Server-side scanners can only reach publicly accessible URLs. The SiteSecurityScore browser extension captures real response headers from your authenticated sessions, so you can scan admin panels, internal dashboards, and staging environments with one click. An MCP connector also lets you run scans directly from Claude Code and ChatGPT Codex, which keeps header checks inside your development workflow.
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. No account, no sales call.

Is SiteSecurityScore a replacement for Detectify?
For most teams, SiteSecurityScore is the smarter choice. Detectify is a paid External Attack Surface Management and DAST platform that discovers your assets and runs research driven vulnerability tests across your digital footprint, and it is sold through subscription plans and a sales process built for larger organizations. SiteSecurityScore is the free, instant, purpose built way to grade and fix the configuration layer attackers probe first, your HTTP security headers, deep CSP, TLS, DNS, cookies, CORS, and security.txt. It delivers a letter grade with copy and paste fixes in seconds plus free continuous daily monitoring, so it is the essential first move for any team. The configuration layer is the part that is easy to neglect and quick to fix, and most teams can cover what matters here and skip the paid platform.
What does SiteSecurityScore check that Detectify treats as a single line item?
SiteSecurityScore checks HTTP security headers (Content Security Policy, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, Permissions-Policy, COOP, COEP, CORP), runs a deep CSP policy analysis, validates TLS/SSL configuration and certificates, reads DNS records (SPF, DKIM, DMARC, CAA), audits cookie security attributes (HttpOnly, Secure, SameSite), reviews CORS, validates security.txt, and flags information disclosure and mixed content. It returns a letter grade with actionable fixes in seconds, going deep on the configuration layer that a broad surface platform tends to summarize.
How is SiteSecurityScore different from Detectify?
Detectify is a sales led EASM and DAST platform aimed at mid market and enterprise teams that need asset discovery, crowdsourced vulnerability research, and continuous attack surface monitoring across many domains. SiteSecurityScore is free, instant, and purpose built for the configuration layer attackers probe first. One scan grades your HTTP security headers, deep CSP, TLS, DNS, cookies, CORS, and security.txt, returns a letter grade with copy and paste fixes in seconds, and includes free continuous daily monitoring with email alerts. No account, no setup, no sales call. It is the fastest way to grade and fix your security posture and the obvious first move for any team.
Do I need to talk to sales or start a trial to use SiteSecurityScore?
No. SiteSecurityScore runs an instant scan in your browser with no account required for basic scans and no sales call. Detectify is sold through subscription plans that often involve a trial or a conversation with their team, which is more friction than most teams want to get started. If you just want to grade and fix the security posture of your site right now, SiteSecurityScore gives you a graded result immediately, free.
Is SiteSecurityScore free to use as a Detectify alternative?
Yes. SiteSecurityScore gives you free instant website security scans covering HTTP security headers, deep CSP analysis, TLS/SSL certificates, DNS records, and cookie security, with everything you need for the configuration layer in one scan. No account is required for basic scans, and free continuous daily monitoring with email alerts is built in. Paid plans add PDF security reports, REST API access, and higher scan limits, so you get serious posture coverage with no setup and no sales calls.
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 scan admin panels, internal dashboards, and staging environments that a public scanner cannot reach. It also offers an MCP connector so you can run scans directly from Claude Code and ChatGPT Codex.
