How to Plan a SafeLine WAF Installation on Debian

Searching for how to install SafeLine WAF on Debian? Start by checking what the official installation guide actually establishes. It lists Linux as the operating system requirement, but the supplied documentation does not name Debian releases or provide Debian-specific package instructions. Treat this guide as a deployment readiness checklist, then follow the official installation procedure once you have confirmed your environment meets its requirements. Official installation guide

Check the host before choosing an installation path

The documented minimum configuration is one CPU core, 1 GB of memory, and 5 GB of disk space. The guide lists x86_64 and arm64 architectures, Docker 20.10.14 or later, Docker Compose 2.0.0 or later, and an ssse3 CPU requirement. These are the published prerequisites; they do not establish compatibility with every Debian release or hardware configuration. Installation requirements

Use the checks provided in that guide to inspect your proposed host:

uname -m
docker version
docker compose version
cat /proc/cpuinfo| grep "processor"
free -h
df -h
lscpu | grep ssse3
Enter fullscreen mode Exit fullscreen mode

Record the results before proceeding. If Docker or Compose is missing, resolve that prerequisite before treating the machine as ready. The supplied sources do not include a Debian-specific package repository setup, so this article does not prescribe one.

Architecture also affects your deployment decision. The installation guide states that ARM installations require a Pro license and that the Personal Edition does not support ARM. Confirm that constraint before allocating an ARM host. Architecture and edition requirements

Choose the documented deployment method

The official guide recommends automatic deployment and states that its installer requires root privileges. It also provides a manual Docker Compose procedure. Choose the route that fits how you administer the server, and use the commands directly from the official guide. Deployment methods

For manual deployment, prepare the configuration decisions first. The documented procedure uses /data/safeline for configuration and data, downloads a Compose file, and creates an .env file. That file includes the management port, database initialization password, internal network prefix, image settings, and architecture suffix. The example management port is 9443; ARM deployments require ARCH_SUFFIX=-arm. After configuration, the documented launch command is:

docker compose up -d
Enter fullscreen mode Exit fullscreen mode

These details come from the manual installation procedure. Review the environment values for your deployment instead of copying placeholders unchanged.

Separate console access from application protection

After installation, the guide directs you to https://<safeline-ip>:9443/. It provides this command to obtain administrator credentials:

docker exec safeline-mgt resetadmin
Enter fullscreen mode Exit fullscreen mode

Use the returned credentials to sign in. Reaching the console confirms that you can administer the installation; application onboarding is a separate documented step. Console access instructions

SafeLine operates as an HTTP/HTTPS reverse proxy: it receives application traffic and forwards permitted traffic to the original application. In the console, open Applications, select Add Application, and enter the application domain, the port SafeLine should listen on, and the upstream application address. For HTTPS applications, the guide instructs you to select the SSL option. It then directs you to resolve the application domain to the SafeLine server's IP address. Application configuration guide

Before changing that domain's destination, record its existing configuration and decide how you will verify normal application behavior. This is an operational planning recommendation, not a documented SafeLine automation feature.

Installation FAQ

Does the documentation explicitly support my Debian version?

The supplied installation page specifies Linux without identifying Debian versions. It supports checking the published prerequisites, but it does not justify a release-specific compatibility promise. Installation requirements

Can I use an ARM server?

The guide lists arm64, requires the ARM configuration suffix for manual deployment, and states that ARM requires a Pro license. Evaluate those conditions together. ARM deployment notes

Does installing SafeLine automatically protect my website?

The documented workflow includes adding the application and directing its domain to the SafeLine server after installation. Complete those routing steps to place SafeLine in the application's traffic path. Protecting an application

How should I validate the deployment?

First check ordinary application behavior. For a site you own or are authorized to test, the application guide also provides attack examples and explains how to inspect blocked requests in the console's attack list. A successful individual test is evidence for that request, not a guarantee about every possible attack. Documented validation examples
