Featured Reviews

Vibhor Goel - PeerSpot reviewer
A single tool for complete visibility and addressing security gaps
Currently, issues are structured in Microsoft Defender for Cloud at severity levels of high, critical, or warning, but these severity levels are not always right. For example, Microsoft might consider a port being open as critical, but that might not be the case for our company. Similarly, it might suggest closing some management ports, but you might need them to be able to log in, so the severity levels for certain things can be improved. Even though Microsoft Defender for Cloud provides a way to temporarily disable certain alerts or notifications without affecting our security score, it would be better to have more granularized control over these recommendations. Currently, we cannot even disable certain alerts or notifications. There should be an automated mechanism to design Azure policies based on the recommendations, possibly with AI integration. Instead of an engineer having to write a policy to fix security gaps, which is very time-consuming, there should be an inbuilt capability to auto-remediate everything and have proper control in place. Additionally, enabling Defender for Cloud at the resource group level, rather than only at the subscription level, would be beneficial.
Lakshmi Padaga - PeerSpot reviewer
Collaborates performance metrics with log data to pinpoint the exact cause of issues and offers error detection
Splunk APM is a robust tool with many capabilities. There are always areas for potential improvement to enhance its functionality and user experience. For Splunk APM, there could be simplified navigation, like streamlining the user interface to make navigation more intuitive for our users, especially those new to APM, which can enhance usability. We can provide more customization options for dashboards and visualizations to help users tailor the platform to their specific needs. There could be more integration capabilities with a wider range of third-party tools and platforms would also be beneficial. By focusing on these areas, Splunk APM can enhance its value proposition, improve user satisfaction, and better meet the evolving needs of organizations monitoring their application performance.
