What Makes BotBlocker Unique

Checks run before WordPress loads, so threats never reach PHP or the database.

Protection before the CMS loads

Starts before WordPress core, plugins, and theme, so malicious traffic never reaches PHP. Supports early-init and MU plugin modes, with protection running before the CMS boots.

Cloud threat analysis

Real-time signatures, global blacklists, and cloud reputation checks close new threats without manual updates. Fresh bot signatures arrive from BotBlocker Cloud.

Bot and traffic control

Blocks scrapers, brute force, fake search engine bots, headless browsers, automation tools, and spam bots. Finds proxies, VPNs, TOR, data centers, and suspicious ASNs.

Intelligent filtering

IP and ASN reputation, User-Agent signature, Accept-Language and GeoIP, reverse DNS (PTR), DNSBL, cookies, JavaScript support, and behavioral anomalies are checked together.

Advanced CAPTCHAs

reCAPTCHA v2 and v3, plus BotBlocker color, digits, images, and shapes captchas for suspicious visitors. Any captcha can be combined with invisible reCAPTCHA v3.

The server stays light

Blocks harmful requests before PHP and MySQL, so load drops and the site holds up under attack. Early blocking means fewer queries and less CPU per bad request.

Transparent privacy

No extra personal data is collected: decisions use technical signals and cloud reputation. GDPR compliant.

How BotBlocker Works

  1. Early start

    All incoming traffic is checked before WordPress, plugins, and theme load.

  2. Instant analysis

    IP, headers, User-Agent, ASN, and behavior are scanned in milliseconds.

  3. Cloud match

    Requests are compared with global threat databases, proxies, VPNs, and bot signatures.

  4. Block or verify

    Malicious visitors are blocked at once; suspicious ones see a CAPTCHA or a check page.

  5. Clean traffic

    Genuine visitors get a fast, secure, stable site.
