# Monitor SSL certificate expiry and security headers

**Use case:** 

Checks each website you list for its SSL certificate expiry date and its main security headers, and flags certificates that expire soon. Choose how many days of warning you want, schedule the task weekly and connect email or Slack in Apify to hear about a certificate before it lapses. Not a security certification or a penetration test. You pay per site checked, plus a tiny start fee per run.

## Input

```json
{
  "startUrls": [
    "https://example.com"
  ],
  "expiryWarningDays": 21,
  "maxSites": 10,
  "concurrency": 2,
  "report": "off"
}
```

## Output

```json
{
  "url": {
    "label": "Site",
    "format": "link"
  },
  "score": {
    "label": "Score",
    "format": "number"
  },
  "grade": {
    "label": "Grade",
    "format": "text"
  },
  "daysUntilExpiry": {
    "label": "Days to expiry",
    "format": "number"
  },
  "httpsRedirect": {
    "label": "HTTPS redirect",
    "format": "boolean"
  },
  "hsts": {
    "label": "HSTS",
    "format": "boolean"
  },
  "securityTxtPresent": {
    "label": "security.txt",
    "format": "boolean"
  },
  "reachable": {
    "label": "Reachable",
    "format": "boolean"
  }
}
```

### 2. Start the "Monitor SSL certificate expiry and security headers" task

The Website Security Monitor Actor will start running based on the input automatically. You can also change all the input fields, like website urls, certificate expiry warning (days), and more, to match your specific use case.

### 3. Receive the "Monitor SSL certificate expiry and security headers" output

Monitor the progress in real time. You will be notified as soon as your dataset is complete and ready for review. Each result includes data such as site, score, grade, and more.

## About this Actor

This example demonstrates how to use [Website Security Monitor](https://apify.com/vizellie/website-security-monitor.md) with a specific input configuration. Visit the [Actor detail page](https://apify.com/vizellie/website-security-monitor.md) to learn more, explore other use cases, and run it yourself.


## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/vizellie/website-security-monitor.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
