Tsunami

Tsunami is a general purpose network security scanner with an extensible plugin system for detecting high severity vulnerabilities with high confidence.

To learn more about Tsunami, visit our documentation.

Tsunami relies heavily on its plugin system to provide basic scanning capabilities. All publicly available Tsunami plugins are hosted in a separate google/tsunami-security-scanner-plugins repository.

Quick start

Please see the documentation on how to build and run Tsunami

Stitch Cloud UI Deployment

Deploy the Tsunami Security Scanner with the "Stitch" Web UI to Google Cloud Platform using Terraform and Cloud Run.

Prerequisites

1. Google Cloud Project: You need a project ID (e.g., my-security-project).
2. Tools Installed: terraform, gcloud, and docker.
3. Authentication: Run gcloud auth login and gcloud auth application-default login.

Step 1: Configuration & Infrastructure

We provide a setup script to configure your environment, including the Google Threat Intelligence (GTI) integration.

Prerequisite: Obtain a GTI (VirusTotal) API request key from VirusTotal API Settings.

# Run the interactive setup script
./setup.sh

This script will prompt for your Project ID, Region, and GTI API Key, then deploy the necessary infrastructure via Terraform.

Alternatively, if you prefer manual Terraform execution:

cd terraform
terraform init
terraform apply -var="project_id=YOUR_ID" -var="vt_api_key=YOUR_KEY"

Step 2: Build & Push Docker Images

Replace YOUR_PROJECT_ID with your actual project ID.

1. Tsunami Scanner Engine

# Return to root directory
cd ..
docker build -t us-central1-docker.pkg.dev/YOUR_PROJECT_ID/tsunami-repo/tsunami-scanner:latest -f cloud.Dockerfile .
docker push us-central1-docker.pkg.dev/YOUR_PROJECT_ID/tsunami-repo/tsunami-scanner:latest

2. Web UI

cd web_ui
docker build -t us-central1-docker.pkg.dev/YOUR_PROJECT_ID/tsunami-repo/tsunami-web-ui:latest .
docker push us-central1-docker.pkg.dev/YOUR_PROJECT_ID/tsunami-repo/tsunami-web-ui:latest

Step 3: Access the UI

1. Go to the Google Cloud Console - Cloud Run.
2. Find the tsunami-web-ui service.
3. Click the URL to open the dashboard.
4. Enter a target (e.g., scanme.nmap.org) to start a scan.
