Sensagraph covers the surface an attacker probes first, across five focused capabilities:

Sensagraph's answer:
Sensagraph shows you your live web applications the way an attacker sees them, from the public internet, with nothing to install.
What sets us apart:
Sensagraph's answer:
Most external scanners are built for large security teams: heavy to set up, priced for the enterprise, and noisy enough that you need an analyst to read the output. Sensagraph is built for the teams those tools overlook.
Sensagraph's answer:
Sensagraph started with a simple, uncomfortable realization: you can write clean code, pass every test, and still be exposed the moment your application goes live.
As developers, we spent our time validating requests, keeping dependencies current, and shipping with confidence. But a passing test suite says nothing about the server the code lands on: the TLS configuration a load balancer negotiates, the admin panel that quietly became reachable, the forgotten open port, or the header advertising a version with a known vulnerability. That outside-in layer is exactly the one attackers probe first, and it stays invisible from inside your own codebase.
The tools that could show us that view were built for large security teams. They were heavy to deploy, expensive, and noisy. Agencies, SaaS startups, and solo developers were left with no practical way to see what the public internet already knew about their infrastructure.
So we built Sensagraph: an agentless platform that scans your live web presence the way an attacker would, ranks what it finds by severity, and turns it into a clear report anyone can act on. No agents, no code changes, and no security team required. Just point it at a domain, verify it once, and see exactly what is exposed, before someone else does.
Sensagraph's answer:
Sensagraph is built for teams that run internet-facing web applications but do not have a dedicated security team watching over them.
Our primary audiences are:
Typical users are developers, DevOps and infrastructure engineers, technical founders, CTOs, and IT or security managers, most often in software, IT services, digital agencies, e-commerce, and other businesses that depend on their web presence.

Check: Go to securityheaders.com and enter your URL. A grade below B means you're missing important ones. - Source: dev.to / 2 months ago
The curl above is the fastest check; all four lines should come back. In a browser, DevTools, Network tab, click the document request, read Response Headers. For a letter grade, securityheaders.com scores you against a known rubric. One quirk: these four alone land a B, and you reach A only once you add Content-Security-Policy. - Source: dev.to / 3 months ago
Remediation: Configure your web server to suppress or mask the Server header. Add security headers like Content-Security-Policy, Strict-Transport-Security, X-Frame-Options, and X-Content-Type-Options. You can use tools like securityheaders.com to check your current header posture. - Source: dev.to / 4 months ago
Step 4: Check your security headers (2 minutes) Visit securityheaders.com and enter your deployed URL. If you get anything below a B, you're missing critical protections. - Source: dev.to / 5 months ago
How to check: Run curl -I https://yourdomain.com and scan the response headers. Or paste your URL into securityheaders.com for a free graded report. - Source: dev.to / 5 months ago
