Findings without context
Severity scores alone cannot tell you which of 1,200 findings an attacker would actually use first.
Sirius · Open source
The operator-first vulnerability scanner.
Sirius is the open-source scanner at the heart of our visibility layer: network discovery, CVE detection, agent telemetry, and operator-driven triage in one interface. Free to run anywhere, and hardened by the operators who use it every day.
In the hands of an operator, the right tool changes everything.
v1.0.0, production-ready scanning and operator workflows
The Open Security Experience
See the surface. Then prove what matters.
Sirius is where the Open Security Experience begins: continuous visibility across the attack surface so operators can find what changed, feed validation, and keep the picture current.

- 02ValidateProve what is exploitable.
- 03See & actPrioritize and remediate.
- 04ImproveRetest and strengthen.
The problem
Vulnerability tools were built for auditors, not operators.
The incumbents got big and stopped listening to the people using their tools every day. The result: thousands of findings, no exploitability context, and security teams that spend more time exporting CSVs than reducing risk. Organizations do not need more findings. They need better decisions.
Workflows that fight the operator
Triage, investigation, and remediation live in different tools, so the people doing the work lose hours to swivel-chairing.
Reports leadership cannot use
A raw export is not a risk story. Boards need to see exposure trending down, not a longer list.
How Sirius works
One framework. Continuous visibility.
Sirius strengthens Discover in the Open Security Experience, and keeps feeding Validate, See & act, and Improve as the environment changes.
01 · Discover
See everything you own. All the time.
You cannot defend assets you cannot see, and point-in-time scans leave weeks of blindness between snapshots. Sirius unifies network scanning, host-based agent telemetry, and continuous discovery in one live environment view.
Nothing on your attack surface goes unseen, and new exposure surfaces the day it appears.
02 · Validate
Know why a finding matters before you fund the fix.
A CVE number and a score do not tell you whether a finding is exploitable in your environment. Every Sirius vulnerability carries attack-surface context (vector, complexity, privileges, CIA impact, and remediation guidance), ready for operator validation.
Decisions get made on evidence, not severity colors.
03 · See & act
Fix the eight that matter, not the eight hundred that don’t.
The Vulnerability Navigator gives operators severity distribution, CVSS-based filtering, grouped views, and fast triage, so the remediation queue shrinks to the work that actually reduces risk.
Your team stops burning hours on theoretical noise.
04 · Improve
Walk into the board meeting with proof.
The Security Command Center turns live exposure into vulnerability trends, severity breakdowns, and risk scoring that track posture over time, snapshot to snapshot, quarter to quarter.
Measurable exposure reduction you can take to the board.
Continuous visibility, in view
See your attack surface as it changes.
- Live inventory
- New host
- Open ports
- Risk rank
- Agent telemetry
- Changed asset
When you need it
Built for operators who are drowning in findings.
Sirius is the lowest-friction way to start seeing your attack surface the way operators do, without buying the entire platform first.
Scanner noise burying real risk?
Thousands of findings, no exploitability context, and a team that spends more time exporting CSVs than reducing risk.
You do not need more findings. You need better decisions.
Weeks of blindness between scans?
Point-in-time snapshots go stale the day after they run. New hosts, ports, and packages appear in the gap.
See exposure the day it appears, not at the next quarterly scan.
Leadership asking if risk is going down?
A raw export is not a risk story. Boards need exposure trending, not a longer list.
Walk in with proof, not another spreadsheet.
Tired of fighting the scanner?
Triage, investigation, and remediation live in different tools, so the people doing the work lose hours to swivel-chairing.
One operator-first interface. Built by people who use it.
The difference
An operator-first scanner, not an auditor’s export tool.
Mainstream scanners were built for auditors. Sirius was built for the people running them every day.
In the hands of an operator, the right tool changes everything.
Prioritize by context and workflow, not another severity color.
Traditional scanner
- Dumps thousands of findings
- Ranks by CVSS alone
- Exports another CSV
- Leaves triage to your team
Sirius
- Continuous live inventory
- Operator-driven triage
- Full finding context
- Trends leadership can use
Human in the loop
The scanner creates leverage. Operators create confidence.
Sirius automates discovery, inventory, and ranking so operators spend time on judgment: which findings matter, which to fund, and which to defer. The tool does not replace the operator. It was built by them.
Technology creates leverage. Operators create confidence.

- Whether risk is trending down
Operator-built
Built by operators who were tired of fighting their tools.
Sirius was not designed by a product committee. It was built by the practitioners running Open Security engagements every day: people with military cyber backgrounds who teach at Black Hat and live in these workflows. When the mainstream tools would not keep up, they built the one that does, and it now powers every engagement we run.
sirius@operator-console
Designed around the daily workflow
Built for the engineer doing the work, not a product committee’s idea of a scanner.
A real operator console
Live agent operations and command execution, not a read-only portal.
Open-source core
Free to run anywhere, hardened and extended by working operators.
Hardened in engagements
The same interface that powers Open Security assessments every day.
Military cyber DNA
Built by practitioners who teach at Black Hat and live in these workflows.
Ready for Sirius Pro
The community scanner is the foundation the managed tier extends.
Close the loop
Discovery is the start of a continuous experience, not a one-off scan.
Sirius keeps the attack surface current so validation, remediation, and readiness have something true to work from. What you find here becomes more powerful when Aludra proves it and Portal tracks the fix.
