# Security Headers Checker (`artifact-machine/artifact-machine-security-headers-checker`) Actor Check security headers (CSP, HSTS, XFO, etc.) on any website. HTTP-only, no browser needed. - **URL**: https://apify.com/artifact-machine/artifact-machine-security-headers-checker.md - **Developed by:** [The Artifact Machine](https://apify.com/artifact-machine) (community) - **Categories:** Developer tools - **Stats:** 2 total users, 1 monthly users, 100.0% runs succeeded, 0 bookmarks - **User rating**: No ratings yet ## Pricing $1.00 / security headers report This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.

They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js/docs.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## The Artifact Machine Security Headers Checker A small artifact for evaluating HTTP security headers on a website — CSP, HSTS, XFO, and more — with per-header grades, a composite security score, and actionable fix guidance. Use this Actor before a security review, compliance audit, launch, or as a regular crawlability-budget security check. It gives teams a quick answer on which security headers are present, which are misconfigured, and how to fix each gap. Pulled from The Artifact Machine: generated, tested, and cleaned up by a human. ### What It Checks - **Content-Security-Policy** — prevents XSS and injection attacks - **Strict-Transport-Security** — enforces HTTPS connections - **X-Content-Type-Options** — prevents MIME type sniffing - **X-Frame-Options** — prevents clickjacking via framing - **Referrer-Policy** — controls referrer information leakage - **Permissions-Policy** — controls browser feature access (camera, mic, geolocation) - **X-XSS-Protection** — legacy XSS filter (deprecated but checked for completeness) - composite security score (0-100) - per-header letter grades (A+ to F) with detailed notes - fix guidance for every missing or weak header ### Best For - security audits and penetration test preparation - compliance checks (PCI DSS, SOC 2, ISO 27001) - website launch and migration security reviews - agency client security diagnostics - monthly security posture monitoring ### Input ```json { "url": "https://example.com" } ```` #### Input Fields - `url`: the page URL to check security headers for. ### Output The Actor writes one dataset item and an `OUTPUT` key-value record with: - composite security score (0-100) and letter grade - per-header results with name, value, grade, note, weight - count of headers by grade (A, B, C, D, F) - actionable issues with impact and how-to-fix guidance Example output fields: - `score`: 0-100 composite security score - `grade`: A-F score band - `headerCounts`: header totals by grade band - `headers`: per-header detail array (name, value, grade, note, weight, description) - `issues`: prioritized fix list with impact and how-to-fix for each missing or weak header ### Limits - This Actor evaluates HTTP security headers only — it does not check SSL certificates, Safe Browsing status, or application-layer vulnerabilities. - It sends a HEAD request first and falls back to GET if HEAD is blocked. - Some sites block automated requests differently from regular browsers; results should be reviewed before client delivery. - The check is point-in-time and does not guarantee ongoing security posture. ### Pricing Use pay-per-event pricing based on completed reports rather than per issue. Suggested starting price: `$1.00` to `$2.00` per completed security headers report after private runtime cost is measured. # Actor input Schema ## `url` (type: `string`): The URL of the page to check security headers for. ## Actor input object example ```json { "url": "https://example.com" } ``` # Actor output Schema ## `results` (type: `string`): Default dataset items. Each item contains the target URL, per-header grades, composite score, and fix guidance for missing or weak headers. ## `summary` (type: `string`): The same single-run summary stored as the OUTPUT key-value record. # API You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup. ## JavaScript example ```javascript import { ApifyClient } from 'apify-client'; // Initialize the ApifyClient with your Apify API token // Replace the '' with your token const client = new ApifyClient({ token: '', }); // Prepare Actor input const input = { "url": "https://example.com" }; // Run the Actor and wait for it to finish const run = await client.actor("artifact-machine/artifact-machine-security-headers-checker").call(input); // Fetch and print Actor results from the run's dataset (if any) console.log('Results from dataset'); console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`); const { items } = await client.dataset(run.defaultDatasetId).listItems(); items.forEach((item) => { console.dir(item); }); // 📚 Want to learn more 📖?
