Featured Reviews

Advanced email filtering has blocked massive spam volumes and prevents unauthorized data leaks

Manager - EUC at Finthrive

Improvements for Mimecast Advanced Email Security include enhancing the user interface and accessibility, particularly regarding admin capabilities to add or modify user accounts. Streamlining this could improve overall usability and security management for users. Reporting is another area needing improvement in Mimecast Advanced Email Security, as the reports provided are not very easy to decipher. With artificial intelligence being integrated into various tools including Mimecast Advanced Email Security, I believe there is potential to enhance functionality, enabling users to ask specific questions and retrieve concise answers instead of overwhelming data. I choose a nine for Mimecast Advanced Email Security because improvements such as better user interface and artificial intelligence integration features would greatly enhance its usability. While no tool is perfect, these adjustments could greatly elevate Mimecast Advanced Email Security's capabilities.

Data governance has strengthened and automation now reduces risk and manual compliance work

Global Leadership Council at a tech company with 10,001+ employees

Varonis Platform offers key features including data discovery, data classification, data analysis, governance, user and entity behavior analysis, also known as UEBA, which helps in ransomware detection, insider threat detection, and compliance reporting. It does a lot of automation from a remediation standpoint, as well as investigation and forensics. The number one feature that makes the biggest difference for my clients is visibility into unstructured data; that is the most difficult for organizations to achieve. They do not have a good understanding of where sensitive data resides, who has access to this data, whether this access is appropriate, and how data is being used. Varonis Platform provides visibility, governance, threat detection, and automated remediation around data. Varonis Platform is a great data discovery platform that provides visibility into sensitive data estimates and how it is being used. Clients have been able to reduce excessive permissions, strengthen their compliance posture, detect insider threats, and ransomware activity, which would otherwise be difficult and manual. Varonis Platform is deployed in my clients' organizations in a combination of all types. Many clients use Varonis Platform in a largely SaaS-based model since it is a data security platform consumed in this way, and many organizations still operate hybrid environments. As far as Varonis Platform is in a position to get the data source and identify systems, it can discover and classify more secure data. Deployment in most of our clients is cloud-based, connecting to Microsoft 365, AWS, or other SaaS applications such as Salesforce. In other environments, it is a hybrid deployment with SaaS and on-premises, including file servers, NAS devices, and AD servers.
