Notas do Editor
- Official Gartner definition: CASBs are on-premises, or cloud-based, security policy enforcement points placed between cloud service consumers and cloud service providers to combine and interject enterprise security policies as the cloud-based resources are accessed. CASBs consolidate multiple types of security policy enforcement. Example security policies include authentication, SSO, authorization, credential mapping, device profiling, encryption, tokenization, logging, alerting, malware detection/prevention and so on.
- There are more than 900 cloud apps per enterprise, on average. If we look at how these applications make their way into the enterprise, about 10% are sanctioned by IT and include apps such as Office 365, Salesforce, Box, and a variety of business applications. IT often doesn’t know about the other 90%. Those fall under the Shadow IT category. Shadow IT is created by apps being brought in by users and lines-of-business, who today feel more empowered than ever because apps are easy to get and use. Whether sanctioned or Shadow IT, many of these apps has an important, and sometimes critical, role to play in the success of your organization.
- The real question, though, is how much of your data is in these apps? What do you think? [build] Last year we did a study with Ponemon to examine the impact the cloud has on the probability and economic impact of a data breach. One of the question we asked IT and security professionals was how much business data they believe is in the cloud. Their (self-reported) estimate is about 30 percent. [build] Whether it’s 30 percent or more than that, it’s only going up from here.
- Discover Cloud Apps and Assess Risk Show App Analytics page and go over top-level stuff we report on (number of app, users, etc.) Pivot to the CCI and talk about how to assess your risk associated with the cloud apps discovered Filter by cloud apps discovered, cloud storage category, and CCI score of poor Zoom into the app Droplr and talk about the 45+ criteria across 7 categories Key point to stress: Discovery is often the starting point for many of our customers. Netskope’s advanced Discovery can help you assess your risk, do due diligence on new cloud apps that you may be considering bringing into your organization, or perhaps getting your arms around what your cloud spend is.

- Advanced Enterprise DLP Show data exfiltration and infiltration use case slide Show a DLP rule where we look for a previous employer and the word confidential Show a document that is sensitive and try to upload it to sanctioned Box Policy is triggered and block message appears (use short video) Key point to stress: Netskope provides the most powerful cloud DLP solution. Not only does it support for than 3,000 data identifiers, 500+ file types and advanced features like proximity and Exact Match, but you can also uniquely apply our DLP and leverage deep context to scan content tied to a real-time activity for both sanctioned and unsanctioned apps as well as content that is resident in sanctioned apps.

- Step 1: As we discussed previously, you need to get a handle on what cloud apps are running in your environment and measure each one’s enterprise-readiness using 40+ factors.
- Step 2: The next step is to understand how those cloud apps are being used. You need visibility into the details of what the activities are taking in account contextual details such as the app, user, specific activity, and device that was used.
- Active Threat Protection Show malware attack fan-out animation Show Box folder being shared with 70+ people and how many of them have sync clients Drag a malware test file to Box and show how it propagates to the local sync clients belonging to the users that have accepted the share Introduce Active Threat Protection - how you enable it in tenant and how it scans app instances and quarantines malware (mock-up dashboard) Summarize and also talk about how the malware that has been spread to sync clients is replaced by a safe tombstone file Key point to stress: This demo is the first phase of our Active Threat Protection, which is about finding and quarantining malware in sanctioned cloud apps. We recently announced Active Threat protection, supporting the ability to find and remediate malware and threats in real-time as they are uploaded, downloaded, or shared across unsanctioned or sanctioned cloud apps.
