Tools and Resources
Nessus is the gold standard for network vulnerability scanning. Security professionals have used it for over two decades and it is genuinely excellent at what it does. It is also $3,990 per year, requires a dedicated server to run, and produces reports that assume you have an IT background to interpret them.
None of that is designed for the person who just wants to know whether their home network is secure.
Nessus is a vulnerability scanner. It probes network devices for known CVEs (Common Vulnerabilities and Exposures), checks service versions against a database of known exploits, and generates a detailed report of every finding with CVSS scores and remediation notes.
It is very good at finding unpatched software vulnerabilities across a large network of servers and workstations. It was built for enterprise IT environments with dedicated security teams who can act on the findings.
Most of what Nessus does is overkill for a home network, and some of it is irrelevant. A home user doesn't need CVSS scores or CVE identifiers. They need to know whether their router is using default credentials, whether their WiFi encryption is up to date, and whether their Windows machine has BitLocker enabled.
The security risks that affect home networks are different from the ones that affect corporate networks. The threats that home users actually face are:
Nessus checks for some of these but it's not optimized for them. And it doesn't check things like BitLocker status, Windows Defender configuration, screen lock policy, or ransomware resilience at all, because those aren't enterprise infrastructure concerns. They are home user concerns.

To be clear: SentinelHome101 is not trying to replace Nessus for enterprise use cases. If you are a security professional managing a corporate network, use Nessus. But if you are a home user who wants to know whether your home network is secure, SentinelHome101 is the more appropriate tool for the job and it's free.
There has been a genuine gap in the market for home network security tools for a long time. The professional tools like Nessus and Qualys are priced for enterprise budgets and designed for IT teams. The free tools like Nmap and Advanced IP Scanner give you raw technical data but no interpretation. And consumer products like router apps are limited to a single device and rarely check anything beyond connectivity.
SentinelHome101 was built to fill that gap. It covers the checks that actually matter for home network security, at a depth that Nmap can't match for non-technical users, and without the cost or complexity of enterprise tools.
The 101 security checks cover six categories:
Every finding includes a plain-English explanation of why it matters and specific steps to fix it. No security background required to understand the results.
If you want to understand what a full audit covers before running one, our guide on how to audit your home network security walks through each category in detail.
