Fing Security

Fing Security checks routers and connected networks for vulnerabilities, exposed ports, and threats. Scheduled router checks look for known security issues, outdated firmware, DNS hijacking risks, and exposed management interfaces. When an unfamiliar device joins, Fing can report its brand, model, and type. It can also scan connected Wi-Fi networks for cameras and spy devices, drawing on a database of over 12 million camera models. The free plan allows up to 3 scans per day; scheduled vulnerability scans and continuous threat detection require a subscription. Fing Agent can run on Raspberry Pi, Docker, or NAS for automated checks around the clock. Integrations include Home Assistant, IFTTT, and the Fing Local API for presence information, network events, and automation. Fing lists IT consultants, MSPs, and small businesses among its users for client audits and monitoring. It is available on Android, iOS, Linux, macOS, Windows, web, and self-hosted deployments, and offers an API. Pricing includes Free at no cost, Premium at $7.99 a month, and Professional at $16.99 a month.

Fing combines router checks, device alerts, and connected-network camera scans, with an option for always-on monitoring through Fing Agent. The free plan is limited to 3 scans per day; ongoing security checks require a subscription.

Fing suits people who want to check home or business network security, including IT consultants, MSPs, and small businesses auditing client networks. Its platform options and monitoring integrations may also suit users managing varied network environments.

Fing Security is a network discovery and security tool for people who want visibility into their router and connected devices. It suits home users and small IT teams looking for automated checks and device alerts, but the free tier is for occasional scans rather than ongoing protection.

Overview

Fing combines network inventory with router vulnerability checks and threat detection. Scheduled checks look for known vulnerabilities, outdated firmware, DNS hijacking risks, and exposed management interfaces. When an unknown device joins, Fing can identify its brand, model, and type, giving users more context than a new entry in a device list alone.

Its discovery approach is hybrid, with asset inventory, scheduled discovery, and SNMP discovery. That range supports both household visibility and more structured network audits. The important qualification is that scheduled vulnerability scans and continuous threat detection require a subscription; three daily scans on the free plan do not amount to always-on security.

Key features

Router and device checks

The router checks focus on concrete exposure and maintenance issues, while unknown-device alerts can help users spot an unexpected connection. These are useful for routine oversight and client audits, but the subscription boundary makes the free plan less suitable for anyone who expects security checks to run automatically over time.

Camera scans and automation

Fing scans connected Wi-Fi networks for cameras and spy devices using a database of more than 12 million known camera models. That broad database makes this a distinctive check for people concerned about hidden cameras on a network, though it is specifically a network scan rather than a general-purpose physical security system.

For continuous automated checks, Fing Agent can run on a Raspberry Pi, Docker, or NAS. Home Assistant, IFTTT, and the Fing Local API support presence data, network events, and custom automation, making Fing more flexible for users who already build workflows around network activity. Fing says it is SOC 2 Type II certified. Its payment data is encrypted and sent directly to PCI DSS-compliant processor Stripe; Fing says it does not collect or store bank or card details.

Pricing

The Free plan costs nothing and includes up to 3 scans per day, internet speed tests, network and ISP reporting, and troubleshooting tools. It is a sensible starting point for occasional checks, but users give up continuous scans and scheduled security monitoring.

Premium costs $7.99 a month, billed monthly, and covers 2 monitored networks, continuous scans, and advanced security and network control. It is the more appropriate fit for an individual or household that wants ongoing checks across a small number of networks.

Professional costs $16.99 a month, billed monthly, and includes 3 + monitored networks, shared workspaces, multi-user collaboration, and advanced reporting. Consultants and small businesses monitoring client networks are the clearest audience for its added network capacity and collaboration tools. Users who need only one or two networks may find Premium the more proportionate option.

Platforms

Fing lists support for Android, iOS, Linux, macOS, Windows, web, API, and self-hosted use. Fing Desktop is available for Windows and macOS, not Linux. Users seeking always-on monitoring can run Fing Agent on Raspberry Pi, Docker, or NAS, while Home Assistant, IFTTT, and the Local API enable integrations with automation setups.

Who it's for

Fing is a good fit for households that want to identify unfamiliar devices and check router risks, especially if they are willing to pay for continuous monitoring. IT consultants, MSPs, and small businesses can use it to audit and monitor client networks, with Professional's shared workspaces and multi-user collaboration better aligned to team use.

It is a weaker choice for someone who needs ongoing protection at no cost: the free plan caps scans at three a day and excludes scheduled vulnerability scans and continuous threat detection. Linux desktop users should also note that Fing Desktop is not available for Linux, even though Linux appears among its supported platforms.

Pros and cons

• Pros: Router checks cover vulnerabilities, firmware, DNS hijacking risks, and exposed management interfaces, providing more security context than device inventory alone.
• Pros: Unknown-device alerts include brand, model, and type, making new connections easier to recognize.
• Pros: Camera scans use a database of more than 12 million known models, and Fing Agent supports always-on checks on Raspberry Pi, Docker, or NAS.
• Cons: The free plan stops at 3 scans per day and does not include scheduled vulnerability scans or continuous threat detection.
• Cons: Premium covers only 2 monitored networks; multi-user collaboration and 3 + monitored networks require the higher-priced Professional plan.
• Cons: Fing Desktop is unavailable for Linux, limiting the desktop option for Linux users.

Alternatives

Network Discovery Software and Network Monitoring are useful category pages for comparing tools by broader network-discovery or monitoring needs.

Choose Domotz if per-device pricing is a better fit: its listed per-device option is $1.50 a month, billed per managed device monthly in bundles of 10. LOGINventory may suit users prioritizing asset inventory, with a free plan covering 20 devices and an Inventory360 plan at €6.50 a year. OCS Inventory is an alternative for users who specifically want open-source inventory software.

NetworkTonic, Gluware, runZero, Infoblox Cloud Network Automation, and LANState are also options to compare.

Verdict

Choose Fing Security if you want router checks, useful context on unfamiliar devices, and a route to automated monitoring through Fing Agent. Its combination of network visibility and security checks makes it a strong fit for home users willing to subscribe and for small IT teams auditing multiple networks. Look elsewhere if ongoing protection must be free, or if Linux desktop software is essential.
