Security headers are invisible until they're checked
A missing HSTS or X-Frame-Options header doesn't show up on a normal site visit — nothing looks wrong until a security scan or a client's IT team flags it.
Security Header Monitoring Software
Security Header Monitoring Software
MonitorMojo helps you verify security headers are present and configured correctly. Each health check reviews CSP, HSTS, X-Frame-Options, and other key headers alongside other health signals.

The Problem
Small misses turn into public failures fast.
Headers get lost in platform or CDN changes
A hosting migration, CDN swap, or theme change can silently drop headers that were previously configured correctly.
One-time audits don't catch regressions
A security review done once at launch doesn't catch a header that gets removed six months later during an unrelated change.
How It Works
1
Add your domain
Enter the website, subdomain, or client property you need to protect.
2
MonitorMojo checks it
Run a real reachability, HTTPS/SSL, response time, and configured health check.
3
Review what needs attention
Use the returned signals to decide what to fix before a browser error or complaint.
Features
Website health checks built for the signals teams forget until they hurt.
security
Named header checks
See which specific headers are present or missing — HSTS, X-Content-Type-Options, X-Frame-Options, and others — not just a pass/fail score.
verified_user
Checked every time, not just at launch
Re-run the same header check after a platform change, CDN swap, or redesign to confirm nothing regressed.
event
Multi-site support
Check header configuration across every site you manage from one place, since header setup often varies host to host.
api
API access
Add a header check as a step in a deploy pipeline or your own automation.
description
Plain-language results
Get a result that explains which header is missing and why it matters, not just a raw response dump.
search_check
Proactive detection
Catch a dropped header after a change before a client's security scanner or IT team finds it first.
Who This Is For
Built for teams closest to the website.
Agencies doing security or technical audits
Add a header check to a recurring audit instead of a one-time review.
Developers verifying a deploy
Confirm header configuration didn't change after a hosting or CDN update.
Website maintenance providers
Include header checks in a care plan alongside uptime and SSL.
Why MonitorMojo
Simple checks for real website risk.
Headers checked alongside everything else
Security headers are one signal in the same check as reachability, SSL, and response time — not a separate tool to remember to run.
Credit-based pricing
Re-check headers after every relevant change without committing to a fixed monitoring subscription.
Specific, not generic
Results name the actual header in question, so you know exactly what to fix rather than a vague security score.
Workflow Guide
What this workflow means
Security header monitoring software that verifies CSP, HSTS, X-Frame-Options, and other HTTP security headers are present and configured correctly across your websites.
In practice, that means reviewing security header presence, browser-level protections, developer review, and remediation notes from one repeatable process instead of waiting for site owners and small teams to hear about a problem secondhand. A check can show whether a URL is reachable, whether SSL appears valid, how quickly the server responds, and whether selected headers are present — it does not replace a security audit or an incident-response team, but it makes the underlying signals visible before they turn into a bigger issue.
Who should use this
This is built for site owners and small teams — specifically for the moment of running a routine check before a visitor finds the problem first. A missing HSTS or X-Frame-Options header doesn't show up on a normal site visit — nothing looks wrong until a security scan or a client's IT team flags it. The same workflow is reusable by anyone with a public URL tied to revenue, leads, or reputation.
Detailed step-by-step workflow
Start by listing the URLs that actually matter for running a routine check before a visitor finds the problem first — not every page on the site, just the ones tied to revenue, signups, or trust. Define the check types for each: reachability, HTTP status, HTTPS/SSL status and expiry window, response time, redirects, and security header presence.
Set a cadence that matches the risk: a monthly review for low-traffic pages, a check right after every deploy for anything tied to revenue. When something fails, triage before assuming cause — hosting, DNS, SSL, code, cache, or a third-party script could all be responsible. Record an owner and a next review date, then re-check after the fix ships.
Checklist and template
Use this template for every review: [URL], [Check Type], [Status], [Issue], [Priority], [Owner], [Detected Date], [Next Review Date]. Describe what the check observed before assigning a root cause — 'response time increased' is a fact, 'hosting is the problem' is a guess until confirmed.
For a recurring report, group findings by reachability, SSL, response time, and security headers, and say plainly when a signal showed no issue rather than implying full coverage.
Common mistakes
The most common miss for site owners and small teams is checking only the homepage while a checkout, signup, or booking flow silently breaks. A close second is assuming SSL auto-renewal always works — it can fail quietly, and an external check is the only way to catch it before a browser warning does. The biggest framing mistake is treating one clean check as proof the whole site is covered.
Practical example
Picture running a routine check before a visitor finds the problem first. A scheduled check flags that a key page is slower than its usual baseline and a security header is missing. See which specific headers are present or missing — HSTS, X-Content-Type-Options, X-Frame-Options, and others — not just a pass/fail score. Instead of guessing, the team logs the observation, assigns an owner, and re-checks after the fix — turning "something feels off" into a closed-loop task with a timestamp attached.
How MonitorMojo helps
MonitorMojo runs the checks behind security header monitoring software — reachability, SSL, response time, and security headers — from one dashboard, with an API and CLI for teams that want it scripted into an existing workflow. Credit-based checks make it practical to run a review exactly when it matters: before a client call, after a deploy, or the moment someone asks whether the site is healthy.
FAQ
Questions teams ask before they check website health.
Which security headers does MonitorMojo check for?
Checks cover common HTTP security headers including Strict-Transport-Security (HSTS), X-Content-Type-Options, and X-Frame-Options, reporting on presence and basic configuration for each.
Why would a header disappear after launch?
A hosting migration, CDN change, or theme/platform update can silently drop a previously configured header, since nothing about the page's visible content changes when a header is removed.
Is this a replacement for a full security audit?
No. It's a recurring check for header presence and basic configuration, not a substitute for a professional penetration test or full security review.
Can I check headers as part of a deploy process?
Yes. A public API is available for triggering header checks programmatically as part of your own pipeline. Documentation is available at /api-docs.
How much does it cost to check headers regularly?
MonitorMojo uses credit-based pricing — you pay for checks you run. View current rates at /pricing.
