Eliminate Blind Spots and Secure Everything in the Cloud
- Your security team needs continuous visibility into your IT attack surface, including cloud environments.
- Legacy vulnerability management tools don’t always work in the cloud, leaving you with blind spots and vulnerable to risks.
- Managing your risks in public cloud infrastructure is challenging, but understanding the role cloud assets play in your Cyber Exposure will help you better protect your organization.
Growing From Vulnerability Management to Cyber Exposure
Managing Cyber Risk in a Dynamic, Cloud-native Infrastructure Requires More Than Legacy Vulnerability Management Tools
Netskope is a cloud access security broker (CASB) vendor whose patented Cloud XD technology gives clients 360-degree visibility into the cloud with data protection.
To manage the company’s cloud-native infrastructure, the Netskope team wanted to evolve its cybersecurity risk management from legacy vulnerability management to a more strategic approach for Cyber Exposure.
Netskope wanted more inclusive and holistic cyber risk management strategies, which revealed there was a gap between what the company wanted to accomplish and existing vulnerability management tools.
The team’s goal was to move from vulnerability overload—data with no context and no insight to quickly prioritize risk and response—to a more effective way to manage cyber risk decisions.
For this transition, Netskope deployed Tenable for continuous visibility into its Cyber Exposure. With Tenable’s advanced reporting, the company can now align its security goals to business objectives.

This integration means you can now better manage your Cyber Exposure across your entire attack surface, including the cloud, to reduce your organization’s cyber risk.

Aligning Cloud Security With Your Cyber Exposure Lifecycle
Cloud solutions are all about speed, scale and usability.
While cloud infrastructure brings many benefits and flexibility to your organization, it can also increase your cyber risk. From asset discovery to benchmarking success, your cloud security processes should correlate with the five phases of the Cyber Exposure lifecycle:
-
Descobrir
If your organization has moved processes and applications to the cloud, then you likely know it’s built for speed and you can easily scale with it. And while that’s great for business efficiencies, it can create new challenges for your security team by inadvertently increasing your cyber risks.
Tenable’s Cloud Connectors for Amazon Web Service (AWS), Google Cloud Platform (GCP) and Microsoft Azure enable detection of new short-lived compute asset deployments across cloud environments. That means you can keep up with cloud-native assets like auto-scaling, on-demand instances and container deployments.
-
Avaliar
If you’re using legacy vulnerability management scanning tools for your cloud environments, you may have blind spots within your attack surface.
Instead of those legacy tools, harden your cloud infrastructure based on Center for Internet Security (CIS) best practices.
From host to workloads and data, Tenable can help you find vulnerabilities, misconfigurations, and other security issues across all your cloud assets so you can plan and prioritize for remediation.
-
Priorizar
Once you’ve assessed all of the assets across your cloud environments, you need to prioritize which vulnerabilities pose the greatest threat to your organization.
Tenable enables you to automatically analyze those risks by evaluating threat intelligence, exploit availability and other vulnerability data so you can prioritize remediation for those most likely to impact your organization in the near future.
Then you can use custom dashboards within Tenable.io to share that information with your DevOps team, and you can automatically send information to your Security Information and Event Management (SIEM) with event context.
-
Corrigir
Once you’ve discovered all of the assets within your IT attack surface—including your cloud infrastructure and discovered your vulnerabilities, misconfigurations and other security issues–you’ll need to prioritize them for risk so you can quickly and efficiently remediate issues.
Tenable enables you to shift left with your cloud security so you can find vulnerabilities before they reach production. You can create secure machine and container images before deployment to prevent additional vulnerabilities and you can integrate your vulnerability management processes into your CI/CD systems.
Additionally, bug-tracking and remediation tools that use APIs enable you to track bugs and seamlessly integrate remediation into your DevOps.
-
Calcular
Finally, all of these steps align to determine your organization’s complete Cyber Exposure.
You can use Tenable’s advanced analytics and scoring to get a clearer picture of your actual organizational risk. From there, you can communicate your cloud security program success and weaknesses to your key stakeholders and team members so you can plan for program growth and improvements.
Internal benchmarking will help you analyze how your program measures up across departments and industry peer benchmarking helps you evaluate your processes against similar organizations.
From here, you can align your security program goals with your organizational goals to facilitate stronger decision-making and planning for your organization.
Protect Your Cloud Environments With a Risk-Based Approach to Vulnerability Management
Legacy Vulnerability Management Tools Can’t Meet All Your Cloud Needs
Cloud environments enable your business to quickly build and scale new infrastructure and rapidly react to customer demands. But without the right capabilities in place to detect and manage vulnerabilities and misconfigurations in an ever-changing environment, this speed and scalability can be a double-edged sword.
Legacy vulnerability management can’t keep pace with this new paradigm, and point solutions lead to information silos without a unified view of all vulnerabilities.
Your security teams need to adopt a risk-based vulnerability management approach to find all vulnerabilities across your attack surface so you can focus on the critical security issues that matter most—vulnerabilities that are the most likely to be exploited.
Here’s a quick summary of how you can adopt a risk-based approach for cloud vulnerability management:
-
Descobrir
Identify cloud assets in a dynamic environment
-
Avaliar
Use scan templates and deployment models built for cloud providers and cloud-native infrastructure
-
Priorizar
Plan and execute vulnerability remediation based on business risk, using machine learning to correlate vulnerability severity, probability of exploitation and asset criticality
-
Corrigir
From development to operations, prioritize which exposures to fix first, and leverage powerful integrations to optimize your entire vulnerability management lifecycle
-

Securing Cloud Infrastructure with Cyber Exposure
Today, all of your cloud assets, data, and workloads must be included in your overall cybersecurity strategy.
To keep your cloud environments as safe as your on-prem assets, you need complete visibility into your cloud infrastructure, supporting compliance, policies and vulnerability remediation plans.
This webinar takes a closer look at the role cloud security plays in your overall cyber exposure and will help you answer three important questions about the security of your cloud environment: Onde estou exposto?What should I focus on first? How do I reduce our exposures over time?

How to Secure Public Cloud and DevOps? Get Unified Visibility
Most security solutions focus on physical, on-prem assets and not the ever-changing world of cloud environments.
This creates challenges for your security team because you need to have flexibility and scalability to keep track of what’s happening within your cloud infrastructure as quickly and dynamically as it changes and evolves.
This blog also explores how you can use cloud connectors, container runtime scanning, and web app scanning to help keep your cloud environments secure.

Cloud-Delivered Security: Why It’s Your Best Bet
Moving business processes to the cloud is a priority for many organizations. It’s a move that often saves money, speeds up processes, and increases flexibility and scalability for organizations of all sizes.
Unfortunately, most security teams still approach vulnerability and risk management from an on-premises focus. Because most on-premises security tools won’t work or are limited in cloud environments, your security team must be ready to adapt and adopt tools focused on also protecting your cloud assets.
So where do you begin?
First, you must understand the current state of all of your assets, including those in the cloud, so you can assess your full organization risk, and you’ll need continuous visibility into all your assets.
In this webinar, you’ll learn more about how you can get this visibility and the benefits of using cloud-delivered security solutions compared to traditional on-premises approaches.
