SafeLine review
An affordable open-source WAF for small teams that need core HTTP protection.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
SafeLine is a self-hosted web application firewall and reverse proxy from CyberServal. It is designed for individuals, small teams, and larger organizations that need to protect websites and web services from malicious HTTP traffic. Core capabilities include web attack detection and blocking, IP-based rate limiting, anti-bot and authentication challenges, web access control lists, HTTP flood DDoS protection, and dynamic HTML and JavaScript protection. Its open-source model and permanent free Personal edition make it especially relevant to teams seeking an inexpensive way to add WAF coverage.
Pricing is structured around Personal, Lite, Pro, and Ultimate editions. Personal costs $0 forever and includes semantic analysis detection, rule-based cyber threat protection, website identity authentication, rate limiting, HTTP flood DDoS protection, malicious IP detection, and Web ACL support. Lite costs $10 per month or $100 per year, adding geo-blocking, Pro threat IP, Discord and Telegram notifications, and attack log export. Pro costs $100 per month or $1,000 per year and adds more powerful cyber attack detection, advanced per-service and global configurations, advanced statistical analysis, a custom interception page, and upstream load balancing. Ultimate is designed for complex enterprise environments and adds dedicated support and customized feature development.
SafeLine’s ecosystem connections include SafeLine MCP Server, Ingress-NGINX, and Kong Gateway. That gives teams specific integration paths while keeping deployment centered on a self-hosted reverse-proxy model. The product is a strong fit for buyers who value open-source software, low entry cost, and practical controls for attacks, bots, rate limits, and access policies. Teams needing broader platform coverage, clearly defined enterprise depth, or a more extensively documented ecosystem should compare alternatives before choosing it. Small teams with straightforward web protection needs are the clearest audience for SafeLine.
