Quelle ansehenSafeLine filtert Traffic, bevor der Origin exponiert wird.
Requests erreichen zuerst SafeLine. Verdächtige Payloads werden erkannt, Bots herausgefordert, Angriffe blockiert und sauberer Traffic weitergeleitet.
01
Prüfen
Analysiert HTTP/S-Requests, Header, Pfade, Payloads und Verhalten.
02
Entscheiden
Nutzt semantische Erkennung, Regeln, Limits und Bot-Challenges.
03
Durchsetzen
Blockiert feindlichen Traffic, protokolliert Ereignisse und proxyt saubere Requests.
SafeLine versteht echtes Traffic-Chaos.
Teams wollen weniger Vorfälle, weniger Alarmrauschen und weniger Origin-Exposure.
Your app logs are full of scanner noise
Suspicious query strings, exploit payloads, and odd paths keep hitting public endpoints before your team can triage them.
Bots are burning origin capacity
Scrapers, brute-force scripts, and HTTP floods make small teams spend time on abuse instead of product work.
You need control, not another black box
Hosted edge security is convenient, but self-hosted products often need local enforcement, transparent routing, and ownership.
Traditional WAF rules are hard to tune
Regex-heavy rule stacks can be noisy, brittle, and painful when developers ship fast or APIs change often.
A self-hosted shield built around HTTP reality.
SafeLine combines reverse-proxy deployment, semantic detection, bot controls, dynamic protection, and access policies into a practical open-source WAF layer.
Semantic web attack detection
Detect SQL injection, XSS, RCE, XXE, SSRF, path traversal, and command injection by understanding request context.
Reverse-proxy enforcement
Put SafeLine in front of web apps, APIs, admin panels, and WordPress sites so the origin receives cleaner traffic.
Bot challenges and rate limits
Add anti-bot challenge, authentication challenge, IP rate limiting, and abuse controls for hostile clients.
Dynamic protection
Use HTML and JavaScript dynamic protection to make scraping, replay, and tampering harder for attackers.
Web ACL and allow/block policies
Apply access control policies around sensitive paths, admin panels, APIs, and high-risk endpoints.
Self-hosted deployment
Deploy with Docker on Linux servers, cloud VMs, or lab environments without introducing a database requirement here.
SafeLine vs. Cloudflare WAF.
They solve overlapping problems, but the operating model is different. SafeLine is for teams that want self-hosted enforcement; Cloudflare is a managed global edge platform.
Lead with free. Upgrade only when the surface grows.
The free edition is the main path for this site: install it, protect an app, then evaluate paid licensing if you need larger limits or Pro-only capabilities.
Recommended

Common deployment questions.
Adapted from the official deployment flow and common WAF adoption concerns.
Can I install SafeLine on Windows?
SafeLine is designed for Docker-based deployment. On Windows, the practical path is usually a Linux VM or WSL2 with Docker, while production should run on a Linux server.
Do I need Kubernetes?
No. The official deployment path is Docker-based and works well on a single Linux host. Kubernetes is optional only if your own infrastructure requires it.
Where should SafeLine sit in my architecture?
Put it in front of your web app as a reverse proxy. Visitors hit SafeLine first, SafeLine filters traffic, and clean requests are forwarded to your upstream application.
Can it protect WordPress, SaaS apps, and APIs?
Yes. The product positioning and docs focus on web applications broadly, including websites, admin panels, APIs, and common self-hosted stacks.
Is Cloudflare still useful if I use SafeLine?
Yes. Cloudflare can still provide DNS, CDN, and edge services. SafeLine is more useful when you want a self-hosted WAF layer near origin.
