Cloud Firewall

Protect your API and web application with multiple firewall layers: bot blocking, threat intelligence feeds, geo-blocking, custom IP blocklists, and user agent filtering.

Cloud Projects Only

This page applies to Cloud / Web / API project types. For Desktop, Mobile, and IoT projects, see On-Premise Firewall.

Firewall Overview

The Cloud Firewall is organized into five protection layers. The first three are managed lists provided by ByteHide. The last two are custom blocklists you define.

Block Bots

Block known bot user agents across 21 categories. Each category can be toggled individually to Block or Ignore.

Categories include:

  • AI Data Scrapers: AI training crawlers and data collection bots
  • Vulnerability Scanners: Automated security scanning tools
  • Data Harvesters: Content scraping and data extraction bots
  • Search Engines: Google, Bing, Yahoo, and other search engine crawlers
  • SEO Crawlers: SEO analysis and monitoring tools
  • Social Media Bots: Social platform crawlers and preview generators
  • Headless Browsers: Automated browser instances (Puppeteer, Playwright)
  • And 14 more categories

Selective Blocking

You probably want to block AI scrapers and vulnerability scanners but allow search engine crawlers. Toggle each category independently based on your needs.

Block Threat Actors

Block IPs from seven threat intelligence feeds maintained by ByteHide. Lists are updated daily at midnight.

FeedTotal IPsDescription
Bruteforce Attackers137,694IPs observed performing brute force attacks
Public Internet Scanners600,071IPs running mass internet scans
HTTP DoS Attackers614M+IPs involved in HTTP denial of service attacks
HTTP Exploit Attackers614M+IPs attempting HTTP-based exploits
Proxy & VPN357M+Known proxy and VPN exit nodes
WordPress Attackers614M+IPs targeting WordPress vulnerabilities
Botnet Actors614M+IPs participating in botnet activity

Each feed can be toggled individually to Block or Ignore. Blocking is instant with no performance impact on your application.

Block Countries

Block all traffic from specific countries using geo-blocking. Search and select countries from the list. Each blocked country is shown with its flag.

Use cases:

  • Comply with regulations that restrict service to certain regions
  • Block traffic from countries where you have no users
  • Respond to attack campaigns originating from specific regions

Custom IP Blocklist

Block specific IP addresses or CIDR ranges. IPs can be added manually or automatically through Workflow Rules using the Block IP action.

Supported formats:

  • Single IP: 192.168.1.100
  • CIDR range: 192.168.1.0/24

When a Workflow rule includes the Block IP action, the attacker's IP is automatically added to this list.

Custom User Agent Blocklist

Block traffic matching custom user agent patterns. Patterns support regex for flexible matching.

Examples:

CODE
bot.*                  # Block anything containing "bot"
curl/.*                # Block curl requests
python-requests/.*     # Block Python requests library
scrapy/.*              # Block Scrapy crawler
