3. Site24x7

Site24x7 Database Monitoring

This is a unique tool for website performance and server, application, and cloud monitoring. DevOps and IT professionals mostly use it to ensure an excellent user experience when accessing a website on different devices.

The Site24x7 system is usually cloud-based except for an agent, which must be installed on the server connected to your enrolled network. This agent uploads vital statistics to the server for processing and functions as the SNMP (Simple Network Management Protocol) manager. This protocol is widely implemented as most network devices have an SNMP agent already installed on them. The agent often scans the device and generates a report known as a Management Information Base (MIB), which gets sent out upon request by the SNMP manager.

The request from the data collector is usually sent as a broadcast and then received by any device on the network. Therefore, the data collector doesn’t need a device’s address to gather important information as it learns the MAC and IP addresses of different devices from the MIBs that return.

The Site24x7 Network Monitor interprets information from the MIBs into an inventory, and the status details are displayed on the dashboard. The monitor also creates a network topology map depending on your network inventory.

Agents are usually allowed to send MIBs without a request called a Trap, and it signals a severe issue with the monitored device. The monitor interprets this as an alert and then displays it on the dashboard. The alert is also sent to technicians through instant messaging, voice calls, email, or SMS.

Key features

  • Auto-discovery
  • Customizable dashboards
  • Performance alerts
  • Network map
  • Traffic monitoring

The software is highly recommended as it’s feature-rich and free. However, the free version doesn’t offer much. So, you could try the premium version for more benefits.

4. Datadog

Datadog Security Monitoring Main-dashboard

This cloud-based software has an agent that gathers metrics and events from hosts to allow you to analyze and monitor our performance data quickly. In addition, Datadog has an updated feed of known suspicious activity to check for potential threats that you need to address. This includes common routes that attackers may use to access your systems, such as domains, hashes, and IP addresses. This also saves you all the hard work of going through loads of data to figure out what attacks you need to look out for.

Datadog categorizes and labels data to help you quickly determine whether the IP address was associated with an anonymizing service, scanner, or attack. Despite your data source, this software analyzes all your logs against all the IP addresses in the feeds. For example, suppose it finds a compromising log such as an anonymized IP connected to a proxy, VPN, or Tor exit node. In that case, it ensures you get enough information from the incident to help you with the investigation.

Key features

  • Monitors network performance both externally and internally.
  • Offers flexible pricing options.
  • Provides auto-discovery.

Datadog allows you to combine it with other monitoring services to ensure more reliability and efficacy. You can download its free trial to get started.

5. ManageEngine

ManageEngine NCM

ManageEngine is a package of security services built around a vulnerability scanner. Its server installs on Windows Server and Windows. However, there are agents for devices on the network that should be established which are available for Linux, macOS, and Windows. This software coordinates different elements to help create a central summary of any detected malicious activity.

The software also provides a live threat intelligence feed where an alarm is raised for any detected exploit. This triggers an automatic system sweep to locate the problem and quickly resolve it. When no alarm is raised, the service performs automatic scans every 90 minutes to check on firewalls and all endpoints.

ManageEngine also has a patch manager that automatically detects whenever specific resources have important available updates. You can instruct the patch manager to automatically install any available updates to ensure all resources work seamlessly.

Key features

  • 90-minute scan cycle
  • Patch manager
  • Web application protection

ManageEngine stands out for its ability to function seamlessly on different operating systems. Its paid version ranges from $245 to $11,545, but you can first install the free version to test its capabilities.

6. Advanced IP Scanner

Advanced IP Scanner

Advanced IP Scanner is software from Famatech Corp designed for Windows operating systems. The tool sounds complex, but it’s very user-friendly. To conduct a scan using this tool, you need to provide the range of IP addresses to be scanned. You can do it manually or using a text file. Once the scan completes, Advanced IP Scanner delivers a report containing responses from every device. It might also display other information such as the MAC address, hostname, and network interface vendor. You can then export the report to CSV if need be.

This software lets you remotely control your devices, including turning them on and off through remote desktop control (RDP) and Radmin.

Another thing that makes Advanced IP Scanner unique is how it finds every device in a targeted scan in a few seconds and provides quick access to their shared resources through FTP, HTTPS, HTTP, or shared folders.

Common features

  • Easy access to network shares.
  • Remote function
  • Finds the MAC addresses.
  • Exports scan results to a CSV file

8. Free IP 

Free IP

Free IP is a popular lightweight standalone IP scanner that can check a hundred computers per second. Unfortunately, the tool is only supported by Windows operating systems and powered by multi-thread scan technology.

It pings a range of IPs to find out who is alive, translates IP to the hostname or vice versa, finds open and closed ports, and grants access to NetBIOS information. By accessing the NetBIOS information, you can see details like active logged users, hostname, workgroup, and the specific MAC address of your device. If need be, you can easily export all this info into a TXT file.

Extra features

  • Fast scanning using multi-threaded technology.
  • Scans different targets per second without using many resources.

Most people love this tool for its simplicity, portability, and user-friendliness. Although the software scans and finds ports quickly, the whole layer 4 TCP/UDP information cannot be customized for further analysis. You can download it for free.

9. Angry IP Scanner

Angry IP Scanner

Angry IP Scanner (also called ipscan) is an open-source network scanner. It’s known chiefly for scanning internet-facing and local IP addresses. The software only works on Linux, Mac OSX, and Windows operating systems. Like Free IP, this tool also offers excellent simplicity, user-friendliness, and portability.

The software pings the target device/network to see whether it’s alive and can also scan ports, find MAC addresses, and resolve hostnames. Additionally, Angry IP scanner allows you to get more information about each target by using special plugins.

Besides scanning IPs, you can also scan ports and save the scan results in different formats such as CSV, TXT, XML, and IP-port list files.

Key features
