Cybersecurity · Tallinn, Estonia · Founded 2019

A bot dedicated to delivering services to protect website from malicious bots, crawlers, scrapers, and hacker attacks MoreLess

BotGuard is a cybersecurity startup that offers a comprehensive web security solution for businesses operating online. Its primary clients include webmasters, eCommerce businesses, and Internet Service Providers (ISPs). Operating in the global cybersecurity market, BotGuard provides a platform-agnostic cloud solution, ensuring 99.9% of companies can benefit from its services, regardless of their existing technology platforms.

The company's primary offering is the BotGuard GateKeeper, an advanced reverse proxy technology. This technology filters web traffic at its landing point, effectively hiding a company's web infrastructure and providing robust protection against Layer 7 (L7) threats and Distributed Denial of Service (DDoS) attacks. In simpler terms, BotGuard GateKeeper acts as a shield, preventing harmful traffic from reaching a company's website or online services.

BotGuard's business model is based on providing these cybersecurity services at a cost calculated to be optimal for each client. This suggests a flexible pricing model that takes into account the specific needs and scale of each client's online operations. The company's revenue is therefore generated from the fees paid by clients for the use of its cybersecurity services.

In addition to bot mitigation, BotGuard also offers a Web Application Firewall (WAF) and Content Scraping Prevention services. These services provide additional layers of protection against common cyber threats, ensuring a comprehensive cybersecurity solution at a competitive price.
