The Defendify Network Vulnerability Scanner is a cybersecurity tool that automatically searches your networks and systems for security vulnerabilities then provides detailed reports to help you understand what risks to consider and where security gaps are. It runs autonomously, leveraging artificial intelligence, machine learning, contextual prioritization, and advanced logic to maximize reach through the network and report regularly on any issues requiring remediation.
External Vulnerability Scanning: Scan against external resources such as firewalls, servers, routers, and cloud applications.
Internal Vulnerability Scanning: Scan internal network assets, like access points, Internet of Things (IoT) devices, workstations, servers, and switches.
What is network vulnerability scanning?
A network vulnerability scan is an automated tool that identifies Common Vulnerabilities and Exposures (CVEs), or publicly known vulnerabilities, in a company’s network, server, and operating systems. To break things down even further, network vulnerability scans fall into two general categories:
External vulnerability scans run from outside of the network, looking for holes (e.g. open ports, configuration issues, etc.) in any public-facing asset (i.e. firewalls, servers, or web applications) that could be exploited by an inbound threat such as a malicious hacker or virus.
Internal vulnerability scans start inside the company network to check individual devices for vulnerabilities that someone – or something – could take advantage of if they gain access to the internal network (e.g. unpatched software with security gaps, malware on an employee’s device, or a malicious insider).
Who is network vulnerability scanning for?
Small and midsized businesses are often the target of cybersecurity attacks because they typically have far less data protection than large enterprises. And with that, it can be much easier for cybercriminals to exploit them as entry points into connections they have with large enterprises, government organizations, partner networks, or consumers.
That’s why it’s critically important that businesses of all sizes regularly run vulnerability scans, as vulnerabilities are numerous, constantly emerging, and hard to keep track of, making them fertile grounds for bad actors looking for new ways to exploit.
Why is network vulnerability scanning important?
Network vulnerability scanning locates potential security holes in your assets. Once activated, it runs autonomously, freeing your IT team up to focus on other needs, including remediation efforts around findings.
Critical vulnerabilities will be marked as such so you’ll know where to locate and prioritize data security issues that might be taken advantage of in the wrong hands.
Your network and firewall are your first line of defense
Your network and firewall are often the first line of defense against cyberattacks, and one of the first things cybercriminals do is look for Common Vulnerabilities and Exposures (CVE) like unpatched software, misconfigurations, SSL certificate issues, and weak security systems. Small businesses are often the target of cybersecurity attacks because they typically have far less protection than large enterprises and can be exploited as an entry point into the large enterprises, government organizations, or consumers who work with them.
Scan monthly and when new assets are added to your network
While multiple compliance frameworks have varying recommendations around the frequency of scanning, there is no single standard for how often you should scan your network for vulnerabilities. Defendify recommends running scans at least monthly. In addition, it’s important to start a new scan any time new assets such as a workstation, server, or firewall, are added to your network.
