SafeLine WAF Server

SafeLine is a self‑hosted Web Application Firewall (WAF) that sits in front of your web services and protects them from a broad spectrum of attacks. By acting as a reverse‑proxy, it intercepts every HTTP/S request before it reaches your application server. This isolation allows SafeLine to examine, filter, and optionally modify traffic without modifying the backend code or infrastructure. The result is a lightweight security layer that can be deployed quickly, scaled horizontally, and managed centrally.

The core value proposition for developers is the “zero‑touch” protection model. Once SafeLine is in place, it automatically blocks common web exploits such as SQL injection, XSS, command injection, and SSRF. It also enforces rate limits to mitigate DoS or brute‑force attempts, and presents anti‑bot challenges that distinguish legitimate users from automated crawlers. For teams building high‑traffic or highly regulated applications, this eliminates the need to write custom security middleware for each new feature or deployment.

Key capabilities include:

• Attack Prevention – A curated rule set that detects and blocks 20+ categories of web attacks, from path traversal to XML External Entity (XXE) exploitation.
• Rate Limiting – Configurable per‑IP or per‑user thresholds that throttle traffic and protect against floods.
• Anti‑Bot & Authentication Challenges – CAPTCHA‑style challenges for suspicious traffic and optional password gates that can be toggled per endpoint.
• Dynamic Code Encryption – On‑the‑fly encryption of HTML and JavaScript assets, making it harder for attackers to scrape or tamper with client‑side code.
• Access Control Lists – Fine‑grained IP whitelists/blacklists and rule‑based policies that can be updated through the API.

In real‑world scenarios, SafeLine shines for SaaS platforms that expose APIs to untrusted clients, e‑commerce sites that must guard against credential stuffing, and internal web services that need to satisfy compliance requirements without reinventing security controls. By exposing a simple HTTP interface for rule management, SafeLine can be integrated into CI/CD pipelines, monitoring dashboards, or AI‑driven threat analysis tools. Developers can query the WAF for audit logs, adjust thresholds on demand, or trigger automated rollback if a new deployment introduces vulnerabilities—all through the same MCP interface that powers AI assistants.

What sets SafeLine apart is its dynamic protection layer. Unlike static WAFs that rely solely on signature matching, SafeLine encrypts served code with a rotating key on each request. This means that even if an attacker captures the payload, it becomes unusable without the decryption context. Combined with proactive bot mitigation and rate limiting, SafeLine offers a comprehensive shield that is both hard to bypass and easy to manage for modern AI‑enhanced development workflows.
