Room For Improvement

Microsoft Defender for Cloud Apps needs improvements in pricing, interface, integrations, alert precision, documentation, and multi-cloud support.

For data loss prevention, it would be useful to be able to drill down into the kind of data being transferred over CloudApp.
Head of Security Operations at a computer software company with 51-200 employees
Defender typically connects to Entra ID, but we have local users on the cloud for database access, SSH, or RDS, and there is nothing produced by Defender regarding those local IAM users.

Microsoft Defender for Cloud Apps would benefit if Microsoft allows users to fine-tune false positives, enabling us to dismiss alerts or make adjustments so that such things don't trigger multiple times in the future.

IT Architect at a logistics company with 10,001+ employees
The pricing is much more affordable than traditional penetration tests.
Manager, Information Technology at a performing arts with 11-50 employees

Featured Reviews

reviewer2777910 - PeerSpot reviewer
Partner & Chief Executive Officer at a consultancy with 51-200 employees
Enforces dynamic policies and blocks risky behaviors to safeguard sensitive data
The fidelity of the signal in Microsoft Defender for Cloud Apps has been a challenge in some areas. There have been instances where the alerts generated have been false positives. A lot of work has to go into scoping and tuning the policies so that actual value can be achieved, especially when not doing outright blocks. When monitoring is the approach, it can be overwhelming for security teams to review all of the alerts and determine which ones require action. When a legitimate alert is found that requires action, the tools are available to take that direction, but it can take considerable time to determine if an alert is real or not, and that represents a problem. There is uncertainty about how well Microsoft is keeping up with the changing landscape of threats, as new artificial intelligence services and software as a service applications appear every day.
Brent Hamlin - PeerSpot reviewer
Infrastructure Manager at a construction company with 501-1,000 employees
Continuous threat scanning has improved remediation time and strengthened executive reporting
The best features that The NodeZero Platform by Horizon3.ai offers include the automated scans, which are great to use; you set it, scope it, and let it go, which works really well. The executive reporting feature is impactful for me as a manager, providing a strong foundation to give quarterly and yearly reports to our executives and board to see the state of our infrastructure from a security standpoint. The level of detail and clarity in the executive reports from The NodeZero Platform by Horizon3.ai absolutely helps me communicate effectively with leadership. They are detailed enough for me to extract the necessary information tailored for the executives and to provide a broader perspective on our mitigation efforts or accepted risk stance and where additional controls exist. The NodeZero Platform by Horizon3.ai has positively impacted my organization by giving us a better continuous picture of our security posture, what's exploitable, and what can be used against the organization. It allows us to run scans whenever needed, unlike a single third-party system that only provides a snapshot in time; our processes must be ongoing as the security landscape is dynamic. NodeZero's endpoint security effectiveness feature impacts my understanding of potential security threats by providing a clear picture of both the external and internal landscapes within my organization, enabling me to prioritize and adjust as needed for vulnerabilities such as WordPress plugin issues or user enumerations and software code version assessments. I have built The NodeZero Platform by Horizon3.ai into our weekly and monthly workflows for security CI/CD, and we scan our externally accessible assets every week to address anything quickly if it comes up. That includes our firewalls, websites, and anything that is an external web server, which we scan weekly, while the monthly scans are for internal systems that feed our security CI/CD pipeline, enabling us to action across and prioritize any vulnerabilities caught by The NodeZero Platform by Horizon3.ai.
