Netskope’s default steering configuration covers standard HTTP (port 80) and HTTPS (port 443) traffic. When a web application is served on a non-standard port such as 6443, the Netskope Client will not steer it by default. To ensure that traffic on port 6443 is both steered and decrypted, the administrator must enable the “Steer non-standard ports” option in the Steering Configuration and then add the specific domain and port as a non-standard port entry. This configuration instructs the Netskope Client to intercept and forward traffic on that port to the Netskope proxy for inspection. No additional Real-time Protection policy is required solely for enabling steering on this port, as existing applicable policies will be enforced once traffic is properly steered to the platform.

When Netskope performs SSL inspection on traffic that uses certificates issued by an internal Certificate Authority (CA) not trusted by Netskope, the platform generates an SSL error and blocks the connection. To resolve this for internal sites using private CA certificates, three approaches are valid: bypassing SSL inspection for the affected sites using a Do Not Decrypt rule removes the certificate validation issue by passing traffic through without inspection; changing the SSL Error Settings in the Netskope UI from Block to Bypass for the self-signed or untrusted certificate error type allows the traffic to flow even when Netskope cannot validate the certificate chain; and importing the internal root CA certificate into Netskope’s trusted certificate store enables full chain validation for all sites using that CA. Creating a Real-time Protection policy to allow access or instructing users to click through errors are not effective or scalable enterprise solutions.

Netskope supports integration with third-party Data Loss Prevention engines that communicate using the Internet Content Adaptation Protocol (ICAP). The Netskope Adapter is the platform component that enables this integration by acting as an ICAP server, receiving content from Netskope’s inline proxy and forwarding it to the external DLP engine for inspection. The Adapter then receives the DLP response and relays the enforcement decision back to the Netskope platform. This is distinct from Cloud Exchange, which handles log and threat intelligence sharing workflows, and the Secure Forwarder, which is used to steer traffic from on-premises environments without a client. The On-Premises Log Parser (OPLP) is used for ingesting log data from on-premises firewalls or proxies into Netskope telemetry.

The Netskope Client uses the nsdebuglog file to record detailed information about traffic steering decisions, including which traffic is being tunneled to Netskope and through which method. When Google Drive traffic is being steered through the Netskope Client in Chrome, the log entry would indicate that the domain is being tunneled to Netskope via the client’s interception mechanism. Option B represents the correct log format that would appear when traffic to Google Drive is successfully being captured and forwarded by the Netskope Client. This log entry format is specific to how the Netskope Client records tunneled HTTPS traffic for Chrome-based browser activity and would confirm that the steering configuration is working as intended for the Google Drive application.

Certificate pinning is a security mechanism used by some native applications to validate that the server’s certificate matches a hard-coded expected value, which causes failures when an SSL inspection proxy substitutes its own certificate during inspection. To allow certificate-pinned applications to function while still being steered to Netskope, two approaches are valid. First, configuring an SSL Do Not Decrypt policy for the specific domains used by the application instructs Netskope to forward the TLS connection without substituting its certificate, preserving the pinned certificate chain end-to-end. Second, configuring Netskope to tunnel the traffic without proxy inspection achieves the same result: traffic is steered to Netskope but bypasses the inspection layer. Creating domain exceptions in the steering configuration would prevent the traffic from reaching Netskope at all, eliminating any visibility or telemetry.

When Netskope is used to inspect outbound SMTP email traffic for DLP violations passing through the corporate mail relay, the Real-time Protection policy must use the “Add SMTP Header” action rather than Block. The reason is that SMTP traffic inspection through Netskope operates inline with the email relay, and the platform adds a custom SMTP header to flag policy-violating emails. The receiving mail relay or email security gateway then reads this header and applies its own enforcement action, such as quarantining or rejecting the message. Blocking the SMTP connection at the Netskope layer can cause email delivery failures and is not the standard inline email DLP enforcement approach. The “Add SMTP Header” action enables cooperative enforcement between Netskope and the downstream email security infrastructure.

When the Netskope Client is configured with dynamic steering and a bypass rule exists for an IP-restricted application, the traffic to that application is not forwarded to the Netskope data plane. Instead, it follows the default network path. For on-premises users, this means the traffic exits the corporate network through the enterprise’s egress point, using the enterprise’s public IP address. This is significant in the context of IP-restricted applications because such applications typically whitelist specific IP addresses. When traffic bypasses Netskope and egresses via the enterprise egress IP, it aligns with the IP restriction requirements. The DHCP-assigned RFC1918 address would not be used as the source IP in internet-bound communications; the public-facing enterprise egress IP is what is seen by the destination application.

When multiple DLP profiles are combined into a single Real-time Protection policy, Netskope evaluates the file against all included profiles simultaneously. If the file matches more than one DLP profile, the policy engine applies the most restrictive action defined within the policy and generates a single DLP incident that references all matched profiles. This behavior allows security teams to see comprehensive match information without creating policy sprawl across multiple individual policies. Creating separate policies for each DLP profile would result in multiple independent incidents but would also complicate policy management and potentially cause inconsistent enforcement due to policy ordering. Consolidating profiles into a single policy is the recommended approach when unified action and centralized incident tracking are required.

Netskope’s tenant restriction capability allows organizations to enforce policies that differentiate between corporate-managed and personal instances of cloud applications such as Microsoft OneDrive. To block uploads to non-AcmeCorp instances of OneDrive, two specific policies work together: Policy 1, which defines the AcmeCorp instance of OneDrive as a managed (sanctioned) instance, and Policy 4, which blocks upload activities to any OneDrive instance that is not the managed corporate instance. Together, these policies use instance awareness to restrict data movement to unauthorized cloud storage instances while permitting use of the corporate-designated tenant. Policies 2 and 3 may address related but different use cases and would not collectively satisfy the requirement of blocking uploads to non-corporate OneDrive instances specifically.

When an SSL Decryption policy is configured in Netskope with the intent to bypass inspection for specific web categories, two common misconfigurations can result in the policy not functioning as expected. The first is selecting an incorrect category; for example, selecting “Financial Services” as a category does not automatically cover all banking websites, as some may fall under different category classifications within the Netskope Cloud Confidence Index (CCI). The second issue is specifying an incorrect action; the SSL bypass policy requires the action to be set to “Do Not Decrypt,” and if the action is mistakenly set to “Decrypt,” traffic will continue to be inspected. A disabled or pending-changes state would affect all policies broadly, not specifically the banking-related traffic.
