BunkerWeb vs Gcore WAAP

BunkerWeb is an open-source web application firewall and NGINX-based server that protects web services as a reverse proxy. Its core protections include HTTPS with automated Let's Encrypt, HTTP security headers, TLS hardening, ModSecurity with the OWASP Core Rule Set and automatic bans for suspicious behavior. It can block known malicious IPs through external blacklists and DNS-based blackhole lists. Bot challenges can use cookies, JavaScript, CAPTCHA, hCaptcha, reCAPTCHA or Turnstile. Supported deployment integrations include Docker, Docker autoconf, Swarm, Kubernetes and Linux. An optional web UI manages instances and configurations, though it is currently supported with Docker and Linux integrations. The open-source plan costs nothing under the AGPLv3 license. A PRO version has pricing based on the number of protected services; Standard has no technical support, while Enterprise includes dedicated technical support. Kubernetes Gateway API mode is in beta. For API access, the documentation recommends an IP whitelist and optionally an API token. Free community support is available through Discord, GitHub Discussions, Reddit, Server Fault and Super User; professional support and consulting are also offered.

Gcore WAAP protects websites, web applications, and APIs against threats including SQL injection, cross-site scripting, and API abuse. It is a SaaS reverse proxy that can sit before a CDN or origin and forward clean traffic onward. Its edge firewall blocks OWASP Top 10 risks, zero-day patterns, and suspicious behavior. Bot Management can admit trusted bots and AI agents, challenge suspicious traffic, and stop abusive automation. API protection includes discovery, schema validation, anomaly detection, and sensitive-data detection. The service also automatically mitigates application-layer DDoS attacks at the edge; Gcore states detection is sub-second. WAAP works with any CDN and supports multi-cloud and hybrid environments, including AWS, Azure, Google Cloud, and customer data centers. Gcore lists 210+ edge PoPs, 200 Tbps of DDoS filtering capacity, and a 99% platform uptime SLA. The Free plan covers one domain and 0.5M requests; Start costs €25 a month for five domains and 1M requests. Prices exclude VAT, and plans have quotas and overage charges.
