仕組み

SafeLine はオリジン公開前にトラフィックをフィルタします。

リクエストはまず SafeLine に入り、通常ユーザーと疑わしいペイロードを分離し、ボットにチャレンジを出し、攻撃をブロックして正常な通信だけを転送します。

01

検査

HTTP/S リクエスト、ヘッダー、パス、ペイロード、挙動を解析。

02

判断

セマンティック検知、ポリシー、レート制限、ボットチャレンジを使用。

03

実行

悪意ある通信をブロックし、イベントを記録し、正常通信を転送。

課題

SafeLine は現実のトラフィックの混乱を理解します。

チームが求めるのは インシデント削減, ノイズの少ないアラート、そしてオリジン露出の低減です。

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.

Solution and features

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.

Cloudflare comparison

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.

Area
SafeLine
Cloudflare
Deployment model
Self-hosted reverse proxy you operate close to origin.
5/5
Cloud edge proxy managed by Cloudflare.
4/5
Best fit
Developers, homelabs, SaaS teams, and self-hosted apps needing local WAF control.
5/5
Teams wanting global CDN, DNS, edge network, and managed platform services.
5/5
Control
Direct routing, logs, policies, and enforcement on your infrastructure.
5/5
Convenient managed controls, but traffic and policy live in an external edge platform.
3/5
Free path
Open-source free edition with practical WAF, bot challenge, ACL, and rate limiting.
4/5
Strong free CDN/DNS baseline; advanced WAF/bot features often depend on plan and add-ons.
4/5
Pricing

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

FAQ

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.
