Network Security Scan

Identify Network Vulnerabilities Before Attackers Exploit Them

Your network plays a key role in your business’s cybersecurity. Servers, workstations, firewalls, routers, remote access systems, cloud-connected devices, and other network assets may have vulnerabilities that attackers could use to gain access or disrupt your operations.

A network vulnerability security scan systematically checks your network to find known vulnerabilities, outdated software, insecure settings, exposed services, and other weaknesses that could raise your cybersecurity risk.

At Tanner Security, our Network Security Scan Services help businesses find and prioritize vulnerabilities before attackers do. We use trusted scanning tools and expert analysis to turn technical results into clear, practical steps your IT team can follow.

We do more than just give you a list of vulnerabilities. We help you see which issues are most important, why they matter, and what your business should do next.

A network security scan is a compliance requirement (PCI DSS, HIPAA, ISO 27001, NISA, and GDPR), and vulnerability management is required for an effective Cybersecurity program.

Like a Network Penetration Test, a network vulnerability assessment is much more cost-effective and can provide a list of actionable items for your IT team to mitigate. Our team specializes in conducting network vulnerability scans and has performed them for over a decade for some of the largest companies in the region.

What Is a Network Security Scan?

A network security scan is a systematic examination of network-connected systems and devices to identify known security vulnerabilities, exposed services, outdated software, configuration weaknesses, and other potential security issues.

Network vulnerability scanning is an important part of an ongoing vulnerability management program. NIST guidance identifies vulnerability scanning as a technique for discovering hosts, open ports, and known vulnerabilities and emphasizes the importance of interpreting scan results and addressing identified deficiencies.

A scan gives you a quick, wide view of your network, much faster than checking everything by hand. But automated scanning is just one part of a strong security program. Experts still need to review the results to spot real risks, filter out false alarms, and decide which issues to fix first.

That is where Tanner Security adds value.

Why Businesses Need Regular Network Security Scanning

New vulnerabilities are found all the time. Software gets updated, new devices are added, settings change, employees come and go, and systems move between on-site and cloud environments.

A network that was secure six months ago might have serious vulnerabilities now.

Regular vulnerability scans give businesses a reliable way to spot changes in their security and find problems before they turn into incidents.

NIST recommends vulnerability monitoring and scanning at defined intervals and when significant new vulnerabilities affecting systems are identified.

For many businesses, regular network security scans are more useful than a one-time check because they help you keep finding and fixing vulnerabilities over time.

Our Network Security Scan Methodology

We start by deciding which parts of your network to check and listing the systems and IP addresses to include. Then we scan the approved environment using proven security testing methods.

The scan evaluates systems for known vulnerabilities, outdated software, exposed services, insecure configurations, and other conditions that could increase the likelihood of compromise.

Our security experts review the results. This step matters because automated scanners can sometimes flag issues that are not real problems, repeat findings, or miss how serious a vulnerability is in your specific environment.

After we analyze the results, we rank the findings based on severity, how easily they could be exploited, which systems are affected, and their potential impact on your business.

You get a clear report that helps your IT team see what should be fixed first.

Internal Network Security Scans

An internal network security scan evaluates systems accessible from within your corporate network.

The assessment can find vulnerabilities in servers, workstations, network devices, internal apps, and other systems. These could be used by a compromised employee computer, a malicious insider, or an attacker who already has some access.

Internal vulnerability scans are especially helpful for identifying outdated systems, missing patches, insecure services, weak settings, and other issues that could allow an attacker to move further into your network.

External Network Security Scans

An external network security scan evaluates systems and services that are accessible externally from the Internet.

This can include public-facing servers, firewalls, VPN infrastructure, remote access services, mail systems, and other internet-facing assets.

External scanning helps businesses see what an attacker could find from outside the network and spot vulnerabilities that might let someone get in.

Regular external scans are especially important as businesses add new cloud services, remote access tools, and apps that face the Internet.

What Does a Network Security Scan Look For?

What a scan finds depends on your setup, but common issues include outdated operating systems, missing patches, exposed services, weak settings, insecure protocols, old software versions, default passwords, and known Common Vulnerabilities and Exposures (CVEs).

The assessment can also find systems or services that should not be exposed and highlight ongoing security weaknesses in your network. Instead of treating every vulnerability equally, we help your team understand which findings represent the greatest risk and where remediation efforts should begin.

Network Security Scanning and Vulnerability Management

A network security scan should not be a one-time task.

Effective vulnerability management is an ongoing process (monthly) that includes discovering assets, identifying vulnerabilities, prioritizing risk, remediating weaknesses, and validating that issues have been addressed.

Regular scans give you the visibility you need to keep this process going.

For example, if your company sets up a new server with a serious vulnerability, regular scans can catch the problem before it goes unnoticed for too long.

This approach also helps leaders show that cybersecurity risks are being watched and managed, not just handled after something goes wrong.

Network Security Scanning for Compliance

Vulnerability scanning can support a variety of cybersecurity and compliance programs, including PCI DSS, HIPAA, ISO 27001, NIST-based security programs, NCUA, CMMC, and customer security requirements.

However, a vulnerability scan is just one part of a complete cybersecurity program, not a full compliance solution on its own.

Depending on the applicable framework and business requirements, additional activities may include risk assessments, penetration testing, security policies, access reviews, vulnerability remediation, incident response planning, and ongoing security monitoring.

Tanner Security can help you see how network vulnerability scanning fits into your overall cybersecurity and compliance efforts.

How Often Should You Perform a Network Security Scan?

How often you should scan depends on your network’s size and complexity, the sensitivity of your data, any regulatory rules, and how often your environment changes.

Many businesses scan for vulnerabilities every month or quarter, while others use more frequent or even continuous monitoring for critical systems.

You should also scan when there are major changes or when new vulnerabilities are found that could affect your systems.

The key is to be consistent. Regular vulnerability management is much more valuable than just doing a scan once a year.

Why Choose Tanner Security?

Network Security Scan vs. Penetration Tests

While both Network Vulnerability Assessments and Penetration Tests are essential for maintaining a secure network, they serve different purposes and involve distinct processes.

  • Network Vulnerability Assessments: These assessments involve automated scanning tools to identify known vulnerabilities within your network. The primary goal is to catalog and prioritize vulnerabilities based on risk. Regular assessments help maintain a continuously updated view of your network’s security posture.
  • Penetration Tests: Unlike vulnerability assessments, penetration tests are manual and goal-oriented. They involve ethical hackers attempting to exploit vulnerabilities to understand how far an attacker could penetrate your network. Penetration tests provide a deeper analysis by demonstrating the real-world impact of identified vulnerabilities.

Network Security Scan FAQ's

A network security scan is an automated and analyst-reviewed assessment that identifies known vulnerabilities, exposed services, outdated software, and configuration weaknesses across network-connected systems as outlined in the CIS controls checklist.

A network vulnerability assessment is a process for identifying, analyzing, prioritizing, and reporting vulnerabilities across a company’s network infrastructure. Vulnerability scanning is one of the 5 ways to secure a network and is an important technical component of the assessment.

A vulnerability scan primarily identifies known weaknesses using automated tools. A penetration test actively attempts to exploit vulnerabilities and security controls to determine what an attacker could actually accomplish. The differences are outlined in the following blog post titled External Penetration Test vs. Vulnerability Assessment: What’s the Difference.

All active Ips should be included. Scanning can include servers, workstations, firewalls, routers, switches, network appliances, virtual systems, and other network-connected infrastructure. Network vulnerability assessments are one of the first investments companies should make first, as outlined in this blog post.

Yes. Internal scans evaluate systems accessible from within the corporate network, while external scans evaluate internet-facing infrastructure.

The appropriate frequency depends on your environment and risk profile. Many businesses perform external scans monthly and internal scans quarterly, with additional scans after major changes or when significant new vulnerabilities are discovered.

Most vulnerability scanning can be performed with limited operational impact, but scanning does generate network traffic and some systems may respond unpredictably. Testing should therefore be carefully scoped and scheduled.

Automated vulnerability scanners generally focus on known vulnerabilities and observable security weaknesses. They cannot reliably identify every previously unknown vulnerability. This is one reason vulnerability scanning should be supplemented with penetration testing and other security assessments.

Common Vulnerabilities and Exposures (CVEs) are publicly documented cybersecurity vulnerabilities assigned unique identifiers. Vulnerability scanners use CVE information, among other data sources, to identify potentially vulnerable software and systems.

Yes. Depending on the scanning technology and scope, assessments can identify certain insecure configurations, exposed services, weak protocols, unnecessary services, and other configuration-related security issues.

The timeline depends on the number of systems, IP addresses, network complexity, scan type, and assessment scope. Many scans can be completed within an hour, followed by additional time for analysis and reporting.

We provide a detailed report that identifies vulnerabilities, explains their severity and potential risk, identifies affected systems, and provides prioritized remediation recommendations.

Yes. Tanner Security can provide remediation guidance and additional cybersecurity consulting to help your business address identified weaknesses.

Pricing depends on the size of the environment, the number of systems and IP addresses, the internal or external scope, the compliance requirements, and the level of analysis required.

Any business that relies on network-connected systems to operate, stores sensitive information, or has regulatory or contractual security requirements can benefit from recurring vulnerability scanning.
