Faced with a snowballing variety of cyber vulnerabilities, today’s IT departments often struggle to identify which are the most critical in the current threat landscape and act promptly to counter them. As the damage potential of these vulnerabilities constantly fluctuates, serious weaknesses can be overlooked while relatively trivial ones receive urgent attention.
To protect your business, high-quality vulnerability remediation has to be a priority – and with attackers growing ever more sophisticated, manual methods are no longer enough. Instead, cloud-based Vulnerability Management (VM) technology allows you to test and monitor your network environment simply and accurately, along with all connected devices.
This cheat sheet is intended to help IT Directors understand what to look for when selecting a vulnerability management solution. You can tick off the checklist to ensure you choose the right provider to get (and stay) on top of your vulnerabilities.
SELECTING A VULNERABILITY MANAGEMENT SOLUTION – YOUR CRITICAL CHECKLIST
What are the top features to look for?
Your Vulnerability Management (VM) solution is only as good as the data it receives. Look for one that can:
Monitor your perimeter, cloud and internal systems
Discover devices that are lost or hiding in your network
Organise devices automatically using customisable rules
Scale seamlessly from a few devices to millions
Scan internal and external networks efficiently
Identify vulnerabilities based on Common Vulnerabilities and Exposures (CVE) guidelines
Track and record the fixing of vulnerabilities
Deliver Six Sigma accuracy as a minimum
Protect scan data against eavesdropping and tampering

Cloud-based VM solutions deliver increased benefits as they don’t require new hardware, or ongoing updates and backups. Securely accessible through your browser, they can reach perimeter systems immediately, scale easily to handle new devices, users and locations, and store results in an objective, tamper-resistant way for audits.
An up-to-date solution will track the state of your systems to provide an evolving picture of your security. They can also make predictions about emerging “Zero Day” vulnerabilities or “Patch Tuesday” issues without requiring new scans.
Look for solutions that can check all systems with a single tool, giving you a consolidated view of your security across the Internet, your private networks, and in the cloud.
Modern, cloud-delivered VM solutions check multiple systems simultaneously. This is done using secure, remotely managed scanners (physical boxes or virtual machines) in different parts of your network, to make internal scanning efficient and minimise the impact on your infrastructure.
You should never have to compromise your security by opening special ports in your corporate firewall.
Consider solutions with robust APIs that enable easy integration with your existing security information and event management (SIEM), risk management (ERM), or governance (GRC) solutions.
With modern networks in a constant state of flux, your VM solution should be able to scan all systems as they move in and out of your network. Make sure it can handle cloud, perimeter and internal devices together in a consistent way.
Look for solutions that search through your perimeter and internal networks, as well as cloud environments like Microsoft Azure and Amazon Web Services, to discover and catalogue the devices running there.
Best-in-class solutions use modern techniques like “tagging”, which programmatically apply labels to each device you encounter (as opposed to older labour-intensive groups).
Modern VM solutions scan different parts of your network in parallel, automatically consolidating results into a single report. This accelerates scanning without overloading your network.
Scans should be able to run according to your chosen schedule (for instance, to coincide with maintenance windows) or repeat continuously.
The best solutions combine vulnerability data from industry-standard sources like computer emergency response team (CERT), software vendors such as Microsoft, as well as information from customers worldwide. Look for solutions that rigorously test each vulnerability definition for accuracy.
New vulnerabilities are discovered every day. A quality VM solution should be able to respond as soon as these are published by your provider.
Only use VM solutions that allow you to specify credentials for securely logging into devices, databases or applications.
Public cloud environments operate strict rules for the scanning of virtual machines. Look for VM solutions that are pre-approved for scanning in Microsoft Azure, Amazon Web Services and Google Cloud Platform and often native integrations.
Accuracy is vital in a VM solution. A missed vulnerability can leave your network open to attack, while “false positives” will waste your time. Look for solutions that use industry-standard processes like Six Sigma and test them for accuracy in your own environment.
Make sure your chosen VM solution stores vulnerability data away from users (e.g. in the cloud) to prevent tampering.
Look for solutions that provide different levels of information, from executive scorecards to detailed, drill-down reports that meet your own needs and criteria.
Advanced VM solutions track your devices to identify those that might be vulnerable to new “Zero-Day” attacks or “Patch Tuesday” issues. This should happen without the need for new scans.
For efficient scanning, choose a VM solution that identifies whether any vulnerability it finds is new, being worked on, already fixed, or accepted as not worth fixing. The best solutions also provide differential reporting that highlights changes from one scan to the next.
Vulnerabilities should be ranked by severity, based on industry standards such as the Common Vulnerability Scoring System (CVSS). This can help you prioritise how and when to address each issue, and is particularly important if you need to give proof that severe vulnerabilities are being promptly identified and fixed.
While all VM products will list individual risks, more advanced solutions will also organise those risks according to the patches that address them. This makes it quicker and easier for IT teams to eliminate vulnerabilities.
Look for VM solutions that provide native support for key mandates like Payment Card Industry (PCI), while allowing you to customise reports to your individual needs.
A best-in-class VM solution will offer a detailed description of each vulnerability, as well as links to the vendor updates or patches needed to fix it.
A top VM system offers automated notification of tickets as well as comprehensive reporting on ticket status. Look for solutions that generate executive summaries across device groups, as well as detailed drilldowns for individual devices, vulnerabilities and users.
VM systems with remediation tracking can usually be configured to prioritise the most severe vulnerabilities. But it’s also important to be able to control the relative priorities of issues across different systems. This allows your IT team to focus on fixing those with the biggest potential impact on your business.
If you already have a trouble-ticketing system in place, look for a VM solution that can work with it to generate, track and close tickets automatically.
Vulnerability scanning is a sophisticated technology that requires deep expertise and commitment. Look for providers who view their VM solution as a core part of their business, not a bullet point on another product’s checklist.
