As enterprises digitally transform and continue to evolve into hybrid models of work, their networks and device ecosystems grow ever larger. This makes an enterprise’s network more difficult to manage and keep secure.
Network scanning tools are part of an enterprise’s security arsenal against malware, ransomware, and other malicious attacks launched against a company’s data and assets.
What are Network Scanning Tools?
Network scanning tools are tools that scan the traffic between devices, firewalls, routers, servers, and more for emerging threats to an enterprise’s network. They look for vulnerabilities in applications, code, operating systems, and more. Upon detecting a vulnerability, the network scanning tool alerts network administrators to suspicious behavior that needs to be resolved, such as an unauthorized log-in, a mismatch between user credentials and the device, or a questionable file being transferred within the network. Network scanning tools are often part of a comprehensive network management platform.
Features of Network Scanning Tools
- Automation: Network scanning tools automatically scan for, detect, and remediate security incidents to prevent alarm fatigue in NetOps staff. They can also be configured to generate automatic reports on a regular basis.
- Classification: Today’s network scanning tools often group similar vulnerabilities and prioritize them based on urgency. That way, NetOps knows what to remediate first.
- Context: Network scanning tools not only identify threats and vulnerabilities but also provide information about the source and, more importantly, a recommended remediation plan.
- Reporting and analytics: Though automation features prominently in network management, that doesn’t mean it should be done on autopilot. For issues that can’t be resolved through automation, a network scanning tool should generate a report or allow self-service analytics to network administrators.
- Database: The network scanner gathers information on the enterprise’s various potential attack surfaces, such as unpatched software. It continuously compares data input to previously saved, known vulnerabilities in the database to identify new threats to programs, ports, scripts, or packet construction.

Benefits of Network Scanning Tools
Automation is the source of many network scanning tool benefits.
Automation helps with some, but not all threats. For vulnerabilities and threats that have been detected before or are low priority, automation is one of many lines of defense that your enterprise has to protect its network.
Your NetOps team benefits from automated tasks in today’s network scanning tools. Without the need to perform repetitive, manual tasks, NetOps team members can focus their energy on more critical security issues affecting the enterprise.
Providing round-the-clock monitoring assistance, automated network scanning tools reduce downtime when an exploit occurs or even prevents system failure entirely. Many vendors today offer configurable network scanning to meet your enterprise’s needs.
Many network scanning tools keep track of past vulnerabilities that help inform and improve your approach to remediating future ones.
Who Needs Network Scanning Tools?
Any company operating online and across multiple devices needs a networking scanning tool. However, enterprises with complex security needs especially require a network scanning tool that covers all potential attack surfaces in its network.
This compilation of top network scanning tool vendors guides enterprises on how to pick the best one for their needs.
Tools that automate routine tasks will be especially valuable for enterprises that operate with small NetOps teams. Depending on the composition and experience levels of your NetOps and SecOps teams, user friendliness may be an important factor to consider as well, as it’s an issue that frequently arises in vendor reviews.
Also consider the solution price, which is usually set up according to time frame, number of users, or number of targets. Locking into a longer subscription period saves your enterprise money.
