Enter your domain names. SEAMUS discovers the rest — subdomains, open ports, vulnerabilities, expiring certificates — and monitors them continuously with AI-powered analysis.
$1,000/yr — not $300/month forever. 2-week free trial, no credit card.
The Problem
What You Get
We evaluate, select, install, and integrate the best open-source security tools into a tested, turnkey platform — then add AI analysis, a management Console, compliance tooling, and enterprise-grade reporting on top. The underlying tools are free. What you pay for is the curation, orchestration, and everything that makes them work together.
A web-based command center with an integrated investigation workflow. Filter findings by severity, expand any vulnerability to see every affected URL and attack payload, then click one button to get an AI analysis or mark it as a false positive. Configuration, documentation, compliance, and exclusion management — all in one place.
Click any finding and ask the AI: "Is this real?" SEAMUS sends the full vulnerability context — including attack payloads, affected endpoints, and remediation guidance — to Claude, who explains the risk, assesses true vs. false positive, and recommends what to do next. Built into the Console, not a separate tool.
Add your root domains — SEAMUS finds the rest. Subdomains, open ports, running services, and web apps are discovered automatically. New assets are detected daily, so forgotten infrastructure doesn't stay forgotten.
HTML for review, Markdown for git, PDF for executives, CSV for SIEM import. Four report formats generated automatically after every scan.
Google Chat, Slack, Microsoft Teams, Discord, email, webhooks, and custom scripts. Topic-tagged alerts for weekly summaries, discoveries, criticals, and cert expiry.
SHA-256 hash-chained audit log, SOC 2 and ISO 27001 control mapping, tool validation reports. Designed to satisfy audit evidence requirements.
Runs on your infrastructure via Docker or Podman. No data leaves your network. No vendor lock-in. Scans keep running even without a license. See requirements
How It Works
SEAMUS runs on Docker or Podman. Works on Linux and Windows (WSL2).
Run ./seamus setup. Add your root domain names — that's it. SEAMUS autodiscovers subdomains and infrastructure from there.
Run ./seamus up. Three containers start: the scanner, the Console, and Uptime Kuma for availability monitoring.
Scans run automatically on your schedule. Daily discovery, weekly deep scans, DAST, and SSL cert monitoring — all out of the box.
Open the SEAMUS Console. Filter by severity, expand any finding to see details and attack payloads, then click to get an AI explanation — or mark it as a false positive with one click.
AI tells you whether each finding is real or a false positive, explains the risk in plain language, and gives you exact steps to fix it. Fix what's real, exclude what isn't. Your next scan reflects the changes.
AI Analysis
To our knowledge, no competing self-hosted EASM tool currently offers integrated AI analysis (as of April 2026). SEAMUS turns raw scan data into actionable insight automatically.

Get NotifiedBuying an EASM Tool?
Whether you choose SEAMUS or something else, these are the questions that separate good EASM tools from expensive disappointments.
Many EASM vendors require a sales call to get pricing. Others quote monthly rates that add up to thousands annually. Look for published pricing with no surprises.
SEAMUS: $1,000 first year, $500/yr renewal — published right here, no sales call.
Some vendors charge by the number of assets, domains, or IPs you monitor. That means your cost grows as your attack surface grows — exactly when you can least afford surprises.
SEAMUS: No per-asset fees. Scan everything you own.
Most EASM tools are SaaS-only. Your scan results, vulnerability details, and infrastructure topology live on the vendor's cloud. If your security policy, compliance requirements, or data sovereignty rules require keeping that data in-house, ask whether a self-hosted option exists.
SEAMUS: Self-hosted by design. Docker or Podman, your network, your data.
Ask whether you keep access to historical scan data after your subscription ends — or whether it disappears.
SEAMUS: All data stays on your machine. Scans keep running. Your data was never anywhere else.
Some vendors reserve AI-powered features for premium tiers or charge separately. Ask what's included at the base price.
SEAMUS: AI-assisted scan analysis is included in every license. You provide your own API key; typical usage costs ~$1–2/month.
Ask how long the trial lasts, whether it requires a credit card, and whether you get full functionality or a limited demo.
SEAMUS: 14 days, full functionality, no credit card, no restrictions.
If you need to demonstrate continuous monitoring to auditors, ask what evidence the tool generates. Ask for specifics: audit log format, tamper resistance, framework mappings.
SEAMUS: SHA-256 hash-chained audit log, SOC 2 and ISO 27001 control mapping, tool validation reports — designed for audit evidence requirements.
Thousands of lines of JSON don't help if nobody reads them. Ask whether the tool summarizes findings, flags what changed, and tells you what to fix first — or whether it just dumps data.
SEAMUS: AI analyzes every scan, delivers plain-English summaries, flags anomalies, and explains CVEs with remediation steps.
