Searching for how to install SafeLine WAF on Debian should start with a compatibility check. The supplied official installation guide lists Linux as the operating system requirement, but it does not provide Debian release requirements or a Debian-specific installation procedure. This article therefore offers a readiness and deployment checklist without claiming that a particular Debian version has been verified. Source: official installation guide
The practical goal is to answer three questions before changing traffic: does your server meet the documented requirements, can you complete the documented deployment process, and have you prepared the application routing?
Check the host before choosing an installation path
Compare your Debian server with the requirements published in the installation guide:
- Linux operating system.
- x86_64 or arm64 architecture.
- Docker version 20.10.14 or later.
- Docker Compose version 2.0.0 or later.
- At least one CPU core, 1 GB of memory, and 5 GB of disk space.
- The listed CPU instruction requirement,
ssse3.
These are the guide’s published prerequisites, rather than a sizing recommendation for your particular workload. Source: deployment dependencies
The guide provides inspection commands including uname -m, docker version, docker compose version, free -h, and df -h. Run the relevant checks and record their results before proceeding. If a dependency is missing, resolve its installation for your Debian environment separately; the supplied sources do not document Debian package repositories or package-manager commands. Source: configuration checks
Architecture also affects the decision. The installation guide says ARM deployments require ARCH_SUFFIX=-arm and a Pro license, and that the Personal Edition does not support ARM. Confirm this requirement before selecting an ARM host. Source: ARM deployment instructions
Choose a documented deployment route
SafeLine’s guide recommends automatic deployment and states that it requires root privileges. It also documents a manual Docker Compose route. Treat these as documented Linux deployment options, while keeping the absence of Debian-specific instructions in view. Source: deployment methods
For a manual deployment, the guide creates /data/safeline, downloads the Compose configuration, writes an .env file, and starts the services with docker compose up -d. SafeLine stores its configuration and data in the chosen directory. Before following that procedure, identify who will maintain that directory and ensure the required disk space is available there.

Review the environment settings instead of copying them without inspection. The documented configuration includes the management port, database initialization password, internal network prefix, and architecture suffix. The example management port is 9443. Source: environment variables
Separate console access from application protection
After installation, the documented console address is https://<safeline-ip>:9443/. The guide uses docker exec safeline-mgt resetadmin to obtain administrator credentials for login. Successfully reaching this console is a useful deployment checkpoint. Source: web UI and administrator account
Application configuration is a separate step. SafeLine operates as an HTTP/HTTPS reverse proxy: it receives application traffic and forwards traffic to the original application after inspection. Source: application protection guide
Prepare the application domain, listening port, and upstream address before adding an application in the console. The guide instructs users to enable the SSL option for HTTPS applications and then resolve the application domain to the SafeLine server’s IP address. Keep the management address and application routing details distinct in your deployment notes. Source: application configuration
Frequently asked questions
Does the documentation explicitly confirm support for my Debian release?
No specific Debian release appears in the supplied installation requirements. The documented operating system requirement is Linux. Use the checklist to assess readiness without treating that broad requirement as release-specific confirmation. Source: dependencies
Is Docker alone sufficient?
The guide lists both Docker and Docker Compose, with separate minimum versions. Check both components before attempting deployment. Source: software dependencies
Does logging into the console mean my website traffic passes through SafeLine?
Console access confirms that you can reach the management interface. The application guide separately requires adding the application details and pointing its domain to the SafeLine server. Verify those routing steps before considering the application setup complete. Sources: console access, application setup
How should I validate the application setup?
As an operational check, exercise normal application journeys after routing is configured. For security validation, the official application guide supplies example attack requests and explains how to inspect blocked requests in the console’s attack list. Use those examples only against an application you control or are authorized to test. Source: application verification
