The report gets filed away, perhaps the most critical findings are fixed &#8212; and then nothing happens for months. But a single scan is like a snapshot: it shows the state of a moment, not the reality of a constantly changing network.<\/p>\n<p>Vulnerability management is not a one-off project but a continuous process. Those who understand and implement this process reduce their risk sustainably. Those who stop after the first scan are lulling themselves into a false sense of security.<\/p>\n<h2>The Vulnerability Management Lifecycle<\/h2>\n<p>Professional vulnerability management follows a clearly defined cycle with five phases. Each phase builds on the previous one, and after the last phase, the cycle starts anew.<\/p>\n<h3>Phase 1: Discovery<\/h3>\n<p>Before you can find vulnerabilities, you need to know what exists in your network. Many SMEs lack a complete overview of their IT infrastructure. Forgotten test servers, old network printers with web interfaces, IoT devices, or shadow IT &#8212; all of these assets represent potential attack vectors.<\/p>\n<p>The discovery phase includes:<\/p>\n<ul>\n<li>Network scanning to identify all active devices and services<\/li>\n<li>DNS enumeration to detect all publicly accessible subdomains<\/li>\n<li>Port scanning to identify running services and their versions<\/li>\n<li>SSL\/TLS certificate verification of all external endpoints<\/li>\n<\/ul>\n<p>A common mistake: only the known systems get scanned. What is not in the asset inventory gets overlooked &#8212; and is often the most vulnerable.<\/p>\n<h3>Phase 2: Assessment<\/h3>\n<p>Once all assets have been identified, the actual vulnerability analysis follows. Here, systems are systematically checked for known security flaws. Modern scanners use extensive databases with over 64&#8217;000 CVEs and thousands of check templates for this purpose.<\/p>\n<p>The assessment phase goes beyond simple port scanning:<\/p>\n<ul>\n<li>Version detection of installed software and operating systems<\/li>\n<li>Checking for known vulnerabilities (CVE matching)<\/li>\n<li>Configuration analysis (default passwords, insecure settings)<\/li>\n<li>Detection of end-of-life software without security updates<\/li>\n<li>DNS and email configuration checks (SPF, DKIM, DMARC)<\/li>\n<\/ul>\n<p>It is important to distinguish between authenticated and unauthenticated scans. Authenticated scans, for example using an agent on the systems, detect significantly more vulnerabilities because they can also check installed software versions and local configurations.<\/p>\n<h3>Phase 3: Prioritisation<\/h3>\n<p>A typical vulnerability scan of a mid-sized SME network easily yields 200 to 500 findings. Not all of them are equally critical, and no IT team can fix everything at once. That is why prioritisation is crucial.<\/p>\n<p>Relying solely on the CVSS score is not enough. A CVSS 9.8 finding on an isolated test system has less priority than a CVSS 7.0 finding on the publicly accessible mail server. Modern prioritisation considers multiple factors:<\/p>\n<ul>\n<li><strong>CVSS score:<\/strong> Technical severity of the vulnerability<\/li>\n<li><strong>EPSS (Exploit Prediction Scoring System):<\/strong> Likelihood of active exploitation<\/li>\n<li><strong>CISA KEV:<\/strong> Confirmed, actively exploited vulnerabilities<\/li>\n<li><strong>Asset criticality:<\/strong> How important is the affected system to business operations?<\/li>\n<li><strong>Reachability:<\/strong> Is the system accessible from the internet or only internally?<\/li>\n<\/ul>\n<p>Those who combine these factors can deploy their limited resources precisely where the risk reduction is greatest.<\/p>\n<h3>Phase 4: Remediation<\/h3>\n<p>Remediation is the step where many SMEs fail. Finding vulnerabilities is relatively easy &#8212; fixing them requires planning, resources, and often coordination between different teams or external service providers.<\/p>\n<p>Successful remediation strategies include:<\/p>\n<ul>\n<li><strong>Patching:<\/strong> Installing available security updates<\/li>\n<li><strong>Configuration changes:<\/strong> Hardening services and systems<\/li>\n<li><strong>Compensating controls:<\/strong> Firewall rules or segmentation when immediate patching is not possible<\/li>\n<li><strong>Decommissioning:<\/strong> Shutting down systems that are no longer needed or maintainable<\/li>\n<li><strong>Acceptance:<\/strong> Documented risk acceptance for vulnerabilities that cannot be remediated<\/li>\n<\/ul>\n<p>Documentation is key. Every decision &#8212; whether remediation, compensation, or acceptance &#8212; should be recorded in a traceable manner. This is important not only for internal quality assurance but also for compliance requirements such as the Swiss Data Protection Act (nDSG).<\/p>\n<h3>Phase 5: Verification<\/h3>\n<p>After remediation comes the step that most people skip: verification. Was the patch actually installed? Did the configuration change close the vulnerability? Were any new issues introduced?<\/p>\n<p>Verification means rescanning the affected systems and then comparing the results. Scan comparisons show at a glance which vulnerabilities have been fixed, which still persist, and whether new ones have appeared.<\/p>\n<p>Without verification, the question remains open as to whether the work invested has actually achieved the desired effect.<\/p>\n<h2>Why SMEs Stop After the First Scan<\/h2>\n<p>The reasons are understandable but dangerous:<\/p>\n<ol>\n<li><strong>Overwhelmed by the results:<\/strong> Hundreds of findings can be intimidating. Without clear prioritisation, nobody knows where to start.<\/li>\n<li><strong>Lack of resources:<\/strong> SMEs often have no dedicated security team. The IT department is already fully occupied with day-to-day operations.<\/li>\n<li><strong>False sense of security:<\/strong> &#8220;We scanned and fixed the critical stuff&#8221; &#8212; until new vulnerabilities are published or the infrastructure changes.<\/li>\n<li><strong>Cost:<\/strong> Regular scans by external service providers are expensive. A single penetration test can easily cost CHF 10&#8217;000 to 30&#8217;000.<\/li>\n<li><strong>Lack of accountability:<\/strong> Without a defined process and clear responsibilities, the topic fizzles out after the initial motivation.<\/li>\n<\/ol>\n<h2>Building a Sustainable Process<\/h2>\n<p>The key to sustainable vulnerability management lies in regularity and automation. The following recommendations help establish a functioning process:<\/p>\n<p><strong>Define a scan schedule:<\/strong> External scans should be conducted at least monthly, internal scans weekly. For critical systems or after major changes, even more frequently.<\/p>\n<p><strong>Set SLAs for remediation:<\/strong> Critical vulnerabilities (CVSS 9.0+) within 48 hours, high (CVSS 7.0-8.9) within 7 days, medium within 30 days. These deadlines must be realistic and binding.<\/p>\n<p><strong>Automate where possible:<\/strong> Scheduled scans, automatic notifications for new critical findings, and trend reports significantly reduce manual effort.<\/p>\n<p><strong>Report regularly:<\/strong> A monthly report to management &#8212; with trends, remediated vulnerabilities, and open risks &#8212; creates accountability and resource awareness.<\/p>\n<p><strong>Use scan comparisons:<\/strong> Comparing consecutive scans shows progress and makes the value of the work invested visible.<\/p>\n<h2>The Role of Vulnerability Management Platforms<\/h2>\n<p>Manual processes with Excel spreadsheets and PDF reports work for ten findings. For 500 findings across dozens of systems, you need a platform that supports the entire lifecycle: from automated discovery through intelligent prioritisation to verification after remediation.<\/p>\n<p>Such platforms typically offer:<\/p>\n<ul>\n<li>Scheduled, automated scans<\/li>\n<li>Combined scoring from multiple systems (CVSS, EPSS, KEV)<\/li>\n<li>Trend analyses and historical comparisons<\/li>\n<li>Remediation status tracking<\/li>\n<li>Reports for different audiences (technical and management)<\/li>\n<\/ul>\n<h2>Conclusion<\/h2>\n<p>Vulnerability management is not a one-time action but a process that only works when it is lived continuously. The first scan is the beginning &#8212; not the end. SMEs that establish a structured, regular process systematically and sustainably reduce their attack surface.<\/p>\n<p>ExposIQ supports SMEs in precisely this process: with over 35 scan engines, intelligent prioritisation through EPSS, CVSS, and CISA KEV, automated scan schedules, and comparison reports, the platform covers the entire vulnerability management lifecycle.
