DLP

Hi Team, Wanted to know if we can restrict the USB file transfer to USB devices via EDLP? Use case- If a user attempts to transfer a file larger than 100MB, the action should be blocked. Thanks

What's the best way to create a DLP Rule that looks for Email Addresses (using the Built In Netskope Email pattern) but not generate hits on our company domain ie @company.com.I was trying to make a custom Entity and then use a not clause in the DLP Rule but not sure if that will give us the behavior I was looking for.

I have been tasked with allowing our user population to have access to the Generative AI category while also protecting the company and our patients by preventing uploads of any files with PHI in them to anything other than our internal instance of Copilot.I have created Realtime policies that I believe achieve this goal, but I have encountered an issue where certain AI sites do not upload the file in a format which Netskope can see into.  Specifically, Grok uploads files as a blob while Quillbot and Heidi Health AI upload the file in blob, json or webm formats.Is there a way for Netskope to be able to view these file uploads and apply our PHI profiles to the upload?  I have not seen any documentation which addresses this, and I am curious if anyone else in the community is running into a similar problem.

ObjectiveHighlight the outcome that improvements to international predefined entities are part of Netskope’s long-term roadmapNetskope existing detection mostly relies on a third-party entity. PrerequisiteThis issue generally applies to all Netskope Standard and Professional DLP modules, including, but not limited to, NGSWG DLP, Email DLP, Endpoint DLP, and more. ContextCustomers can test pre-defined identifiers in their own languages, particularly in non-English regions, to verify whether they function correctly. They may only trigger the sample data demonstrated in the UI, so using a variety of real-life samples is highly recommended for more accurate verification. Do You Know?Non-numerical identifiers such as addresses, names, or terms are likely to bypass Netskope’s DLP detection mechanism without triggering alerts or appearing in DLP incidents. This means the administrator will be unable to track or investigate the data leakage incident. NotesWe’ve discovered that others have alre

How can I change the Status for more then 100 incidents at a time, which is the dashboard limit? I have thousands of incidents created from a retro-active scan and would like to add my own custom status to them all at once.

ObjectiveThe combination of English characters and other special characters is treated as a single word. Netskope Regex does not support detection when English characters are combined with uncommon symbols, even underscore, and the specification of Netskope Regex rules remains unclear. PrerequisiteThis issue generally applies to all Netskope Standard and Professional DLP modules, including, but not limited to, NGSWG DLP, Email DLP, Endpoint DLP, and more. ContextCustomers can validate this issue by adding an underscore (“_”) or random characters after the English keyword they want to detect, as demonstrated below. Do You Know?Users can easily bypass Netskope’s DLP detection mechanism without even decomposing the keywords. This means administrators will be unable to track or investigate potential data leakage incidents.We have requested clearer instructions on how Netskope defines Regex rules, but so far nothing has been provided. NotesWe’ve discovered that others have already raised si

From this article, it mentions the feature flag Netskope Entity Modifier. Could you clarify the difference in behavior before and after it is enabled?Note:Can we suggest allowing a longer period for comments on articles? Otherwise, we have to create a new article just to ask follow-up questions.

I used the locally installed Postman application to send API POST requests with test data to evaluate whether Netskope could detect them. While SkopeIT is logging the events, the policy doesn't seem to be triggering, and I’m unable to view the actual data being transmitted in the API request. Has anyone encountered this issue or have insights on what might be going wrong?

ObjectiveHighlight the outcome that Netskope does not re-examine files with the same MD5 hash permanently. PrerequisiteThis issue generally applies to all Netskope Standard and Professional DLP modules, including, but not limited to, NGSWG DLP, Email DLP, Endpoint DLP, and more. ContextCustomers can initially upload a file that contains no detectable data identifiers. Later, they may modify only the file name to include sensitive keywords. As a result, they can bypass Netskope’s DLP detection mechanism, potentially leaking sensitive information through the file name alone. Do You Know?If the administrator has not changed the DLP policies that should have been triggered, such data leakage will not generate any forensic records or DLP violation alerts. This means the administrator will be unable to track or investigate the data leakage incident. NotesWe’ve discovered that others have already raised similar concerns. I encourage you to vote for this feature as well, as this design issue d

At least two years ago, users were already raising similar concerns to the ones we are now requesting.However, in the App Catalog (CCI), Google Docs still only shows “discovery only” support. Google Slides and Google Sheets are not even listed in the catalog at this moment.  I sincerely believe that Google Workspace is one of the most popular enterprise ready SaaS suites.I’m genuinely curious about your thoughts on this and how your companies currently monitors or regulates user activity within Google Workspace.If you agree, let’s vote together for this feature request. 

Here's an article for Netskope on blocking Base64 encoded sensitive data using custom regex, along with the step-by-step DLP policy creation process. Blocking Base64 Encoded Sensitive Data with Netskope DLP: A Step-by-Step Guide In today's cloud-centric world, organizations face the persistent challenge of preventing sensitive data from leaving their control. While traditional DLP solutions are effective against clear-text data, a common evasion technique involves encoding sensitive information, particularly using Base64, to bypass detection. This article will demonstrate how Netskope's powerful DLP capabilities, combined with custom regular expressions, can effectively block the sharing of sensitive data transformed into Base64 encoded strings.The Challenge: Evading DLP with Base64 EncodingBase64 encoding is a method of representing binary data in an ASCII string format. While legitimate for many purposes, it can be misused to obscure sensitive information like credit card numbers, so

Since deploying the latest golden release of the NS client (v126.0.0.2387) the Last Event field for all systems shows 55 years ago. Is this going to be fixed? 

We have created a policy for USB content control with size limit 50 mb.Issue faced here is if i share file of 40 MB and another of 15 mb it get shared.Use case is we want to restrict complete data transfer over 50 mb not file size The file size limitation is enforced per file, not per session. What we are observing is the expected behavior by design. If your expectation is for Netskope to track the cumulative file size uploaded within a session , for example, a user uploads a 40 MB file at 10:00 AM and then another 15 MB file 15 seconds later, totaling over 50 MB , this functionality is currently not supported.

As a customer facing company, we regularly receive booking-related emails from customers and partners that contain Personally Identifiable Information (PII) such as passport numbers, ID documents, and travel itineraries. To prevent external data leakage, we’ve implemented Netskope DLP to monitor outgoing emails for PII. However, we’re facing a challenge: When our employees reply to incoming emails (even without including any PII in their response), Netskope DLP still quarantines those replies. This is because it detects the original PII from the customer’s message in the reply thread. We want to understand if there’s a way to configure DLP policies so that it only quarantines emails that are originated internally and contain PII, and not block replies to incoming messages that happen to include previously received PII. Is there a solution or best practice to achieve this behavior?

I understand that Netskope’s DLP supports multiple languages and offers high detection accuracy. Could you please share whether the keyword matching inspection is performed using external libraries, or if Netskope uses an in-house developed engine?If external libraries are being used, would it be possible for you to disclose information about them?I am particularly interested in how Netskope has addressed challenges such as multilingual support and detecting word boundaries accurately.

When creating a policy to detect email addresses, I used the following regular expression:[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}However, the string "csv test" triggered a detection, even though it does not contain an "@" symbol and therefore should not match the expression above.Is there any limitation or specific behavior in how regular expressions are interpreted on the Netskope side that might explain this?

Hi, Some customers asked about DLP support for Claude.AI and Perplexity.AI.They are on the roadmap? If so, there’s any estimate on when will it be available? Regards,Rodrigo Borges

What is the definition of "Formpost," which is one of the activity types?

Anyone concerns about Email draft can not be detected by Netskope?On App Catalog it says “Create, Edit, Post, Send” support DLP.On the Application Events, ObjectID can successfully be fetched and we also can clearly saw the activities and content through DevTools.However, DLP policy is not triggered but the action is recorded.We also created a support case on this but L3 support responded and claimed it should be related to SMTP DLP module. We are curious if anyone else has encountered this and have similar concern as we do. 

Are there any planned integrations with Cyera for data classification label usage in DLP policies?Does anyone have experience with this product and use case?Thanks
