Everything you ever wanted to know about security policy management, and much more.
Network vulnerability scanning provides in-depth insight into your organization’s security posture and highlights the specific types of vulnerabilities attackers may exploit when targeting it.
These tools work by systematically scanning your network environment — including all desktops, laptops, mobile endpoints, servers, and other assets for known weaknesses and misconfigurations. Your analyzer then produces a detailed report that tells you exactly how hackers might breach your systems.
Find out how these important tools contribute to successfully managing your security policies and protecting sensitive assets from cybercriminals and malware.
Network vulnerability scanners are cybersecurity solutions typically delivered under a software-as-a-service (SaaS) model. These solutions match your network asset configurations with a comprehensive list of known misconfigurations and security threats, including unpatched software, open ports, and other security issues.
By comparing system details against a comprehensive database of known vulnerabilities, network scanning helps pinpoint areas of weakness that could potentially be exploited by threat actors. This proactive approach is essential for maintaining robust network security and protecting sensitive data from unauthorized access and cyberattacks.
This provides your organization with several valuable benefits:
The best network security vulnerability scanners have several important features in common:
Initial network mapping is the first step in the vulnerability scanning process. At this point, your scanner maps your entire network and identifies every device and asset connected to it. This includes all web servers, workstations, firewalls, and network devices.
The automatic discovery process should produce a comprehensive map showing how your network is connected, and show detailed information about each network device. It should include comprehensive port scanning to identify open ports that attackers could use to gain entry to the network.
The next step in the process involves leveraging advanced detection techniques to identify known vulnerabilities in the network. Most network vulnerability scanners rely on two specific techniques to achieve this:
This step involves checking network assets for known vulnerabilities according to their unique risk profile. This includes scanning for outdated software and operating system versions, and looking for misconfigurations in network devices and settings.
Most network scanners achieve this by pinging network-accessible systems, sending them TCP/UDP packets, and remotely logging into compatible systems to gather detailed information about them. Highly advanced network vulnerability scanning tools have more comprehensive sets of features for identifying these vulnerabilities, because they recognize a wider, more up-to-date range of network devices.
This step describes the process of matching network data to known vulnerabilities and prioritizing them based on their severity. Advanced network scanning devices may use automation and sophisticated scripting to produce a list of vulnerabilities and exposed network components.
First, each vulnerability is assessed for its potential impact and risk level, often based on industry-wide compliance standards like NIST. Then the tool prioritizes each vulnerability based on its severity, ease of exploitation, and potential impact on the network. Afterwards, the tool generates a detailed report outlining every vulnerability assessed and ranking it according to its severity. These reports guide the security teams in addressing the identified issues.
Scanning for vulnerabilities once is helpful, but it won’t help you achieve the long-term goal of keeping your network protected against new and emerging threats. To do that, you need to continuously monitor your network for new weaknesses and establish workflows for resolving security issues proactively.
Many advanced scanners provide real-time monitoring, constantly scanning the network for new vulnerabilities as they emerge. Regular updates to the scanner’s vulnerability database ensure it can recognize the latest known vulnerabilities and threats. If your vulnerability scanner doesn’t support these two important features, you may need to invest additional time and effort into time-consuming manual operations that achieve the same results.
Security leaders must pay close attention to what happens after a vulnerability scan detects an outdated software patch or misconfiguration. Alerting security teams to the danger represented by these weaknesses is only the first step towards actually resolving them, and many scanning tools offer comprehensive integrations for launching remediation actions.
Remediation integrations are valuable because they allow security teams to quickly address vulnerabilities immediately upon discovering them. The alternative is creating a list of weaknesses and having the team manually go through them, which takes time and distracts from higher-impact security tasks.
Another useful integration involves large-scale security posture analytics. If your vulnerability assessment includes analysis and management tools for addressing observable patterns in your network vulnerability scans, it will be much easier to dedicate resources to the appropriate security-enhancing initiatives.
There are two major categories of features that network vulnerability scanning tools must offer in order to provide best-in-class coverage against sophisticated threats. Keep these aspects in mind when reviewing your options for deploying vulnerability scans in your security workflow.
AlgoSec is a network security platform that helps organizations identify vulnerabilities and orchestrate network security policies in response. It includes comprehensive features for managing firewalls routers, and other security device configurations, and enables teams to proactively scan for new vulnerabilities on their network.

Choosing the right vulnerability management tool requires in-depth knowledge of your organization’s security and IT infrastructure context. You need to select the tool that matches your unique use cases and security requirements while providing the support you need to achieve long-term business goals.
Those goals may change over time, which makes ongoing evaluation of your security tools an even more important strategic asset to keep in your arsenal. Gathering clear and detailed information about your organization’s security posture allows you to flexibility adapt to changes in your IT environment without exposing sensitive assets to additional risk.
AlgoSec provides a wide range of flexible options for vulnerability scanning, policy change management, and proactive configuration simulation.
