## What's an Apify Actor?

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases.
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.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.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/platform/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.

# README

## 🛡️ CVE Monitor · NVD · CISA KEV · EPSS

Monitor new and updated CVEs for the vendors and products you care about — enriched with CISA Known-Exploited flags and EPSS exploit-probability. Built for security & vulnerability-management teams.

### ⚡ What you get
| Field | Description |
|---|---|
| `cveId` | CVE identifier |
| `cvssScore` / `cvssSeverity` | CVSS base score & severity |
| `knownExploited` | In CISA KEV (actively exploited) |
| `epssScore` | EPSS exploit-probability (0-1) |
| `published` / `lastModified` | Timeline |
| `description` / `references` | Summary + source links |

### 🎯 Use cases
1. Vulnerability-management teams tracking their tech stack
2. Security vendors / MSSPs feeding alerting pipelines
3. Threat-intel analysts prioritising by KEV + EPSS
4. Compliance teams evidencing CVE monitoring

### 🚀 Sample inputs
```json
{ "keywords": ["openssl","fortinet"], "sinceDays": 7, "maxPerKeyword": 20 }
````

```json
{ "keywords": ["apache log4j"], "severityMin": "HIGH" }
```

### 📦 Sample output

```json
{ "cveId": "CVE-2026-1234", "cvssScore": 9.8, "cvssSeverity": "CRITICAL", "knownExploited": true, "epssScore": 0.94, "published": "2026-06-01T00:00Z", "keyword": "openssl", "description": "..." }
```

### 📊 Sample Output

![Sample output](https://api.apify.com/v2/key-value-stores/8gLgXMBveEI1tTz1z/records/cve-vulnerability-monitor-output.png)

### 🛠 How it works

1. **Source** — official NVD CVE API 2.0 (`services.nvd.nist.gov`), no login.
2. **Enrich** — joins CISA KEV (known-exploited) + FIRST.org EPSS scores.
3. **Filter** — by keyword, look-back window, and minimum severity.
4. **Schema** — one row per CVE with prioritisation fields.
5. **Fallback** — rate-limit-aware; failed keywords are logged and skipped.

| Cves | Cost |
|---|---|
| 100 | ~$3.00 |
| 500 | ~$15.01 |
| 2,000 | ~$60.01 |
Apify's **$5 free credit** covers ~166 CVEs. [Start free →](https://apify.com/?fpr=2ayu9b)

### ⚖️ Legal & data sources

Data from public, official feeds: NVD (NIST), CISA KEV, and FIRST.org EPSS. Government/public-domain and openly-licensed sources; identified User-Agent; rate-limit-respecting.

### ❓ FAQ

**How fresh?** Live from NVD at run time; use `sinceDays` for the window.
**What is KEV?** CISA's Known Exploited Vulnerabilities catalog — actively-exploited CVEs.
**What is EPSS?** FIRST.org's probability a CVE will be exploited in the next 30 days.
**Do I need an API key?** No.
**Can I filter severity?** Yes — `severityMin` = LOW/MEDIUM/HIGH/CRITICAL.
**By product?** Use `keywords` (vendor/product terms).

### 🆘 Troubleshooting

- **Few results** — widen `sinceDays` or broaden keywords.
- **Rate-limited** — the actor paces NVD calls; large keyword lists take longer.
- **No EPSS for a CVE** — EPSS may not score very new CVEs yet; field is null.
- **Too noisy** — set `severityMin: "HIGH"`.
