Provides robust email security features but requires improved modernization and complexity management
Modernization is an area that could be improved for Cisco Secure Email Threat Defense, as some features have lagged behind newer competitors, potentially offering more advanced analysis capabilities. The initial setup is not straightforward and requires expertise and time to master configurations such as spoofing and DLP. More control over backend functionalities and simplifying rule management could enhance user experience. The product's complexity at times results in redundant rule sets that are difficult to untangle, highlighting the need for streamlined management systems and a more user-centric approach to system configuration. Furthermore, the pricing might deter new users who could opt for alternative, more cost-effective solutions.

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

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Currently, the ease of deployment is the low-hanging fruit for Cisco email security."
"The product offers protection, email security, anti-spam, and antivirus."
"It has an efficient email filtering feature."
"This solution is easy to use."
"Cisco has a threat mechanism called cloud-based Talos, where all the threats are inbuilt."
"The ability to see east-west traffic is its most valuable feature. Traditionally, email defense focuses on north-south, inbound-outbound, egress-ingress traffic. With Cisco Secure Email Cloud Mailbox, it's able to quickly identify, track, tag, and categorize emails that are internal. That can typically give us visibility into if there's an internal compromised account (for example). Someone can then use that internal compromised account to email additional accounts with either malicious software or links, but internal within that Office tenant. Effectively, that email message never leaves the tenant. Any of the mail gateways really do not have any method or way of seeing this traffic since it's not leaving the environment."
"On ease of use, it rates very high."
"The solution is stable."
More Cisco Secure Email Threat Defense pros
"I also appreciate the reporting feature, which allows for the extraction of various reports based on specific needs. These reports can be used for audit purposes, such as tracking changes in file locations or deletions."
"This solution informs us about who's moving data, whether accidentally or on purpose."
"The analytics would have to be our most valuable feature."
"Varonis offers robust data access governance, allowing us to understand which sensitive data exists and who has access to it."
"The solution's classification engine is highly configurable and efficient."
"The 24/7 support is the most valuable feature, and they have been able to answer support questions pretty quickly."
"Varonis Platform support has been amazing throughout every step that we have taken with them."
"The most important feature is remediation. In remediation support, there is no group permission. We'll go ahead and remediate the access from the Dell folder to the parent folder."
More Varonis Platform pros
 

Cons

"The solution is a bit expensive. It could be cheaper."
"From a technical point of view, Cisco is far behind in terms of cybersecurity, and it has to improve very much."
"We encounter issues while searching for missing emails."
"The pricing could always be better."
"Cisco's multiple product lines and verticals made this just one of their many verticals, and we could see a shift in focus."
"The behavioral analysis capability of Cisco Secure Email Threat Defense is not particularly helpful for identifying new, evolving threats within my company, as it keeps flagging legitimate emails as malicious."
"The tool gives false positives and it needs to be more accurate. I would like to see AI as a new feature."
"There is still room for improvement in terms of integrations with other Cisco tools and non-Cisco tools. There is also some room for improvement needed in terms of the reporting."
More Cisco Secure Email Threat Defense cons
"Varonis Platform could be improved because when I used it, we had a significant issue related to the large volume of data on that file share."
"Varonis requires more access permissions for its core functions compared to competitors, which can be a concern for companies about data safety."
"I'd like to see automatic updates for this solution. Currently, it's a manual process to update all the keywords."
"For unstructured data monitoring, it's one of the top ones, if not the top one, due to its usability."
"While Varonis Platform is powerful, the initial data scanning and indexing can take significant time in large environments."
"The GUI should be more functional. There should be a process for connecting through Chrome, Internet Explorer, etc."
"The troubleshooting capabilities could be improved. It has so many interconnected components."
"It would be beneficial if the reporting in Varonis Platform could use PDFs instead of Excel for better graphs, as the dashboards are really good, and it would be nice to have simplified dashboards in PDF for business reporting purposes."
More Varonis Platform cons
 

Pricing and Cost Advice

"The solution’s pricing is manageable."
"Cisco Secure Email Cloud Mailbox does not have any competition with Sophos, Trend Micro, or other vendors of the world. However, there is a pricing premium for the solution. One has to look at it from that angle that while they are buying Cisco, there will be a premium, and Cisco justifies that premium value. That's why they're charging a high price."
"The feedback from vendors and customer is that it is expensive."
"It is expensive compared to other vendors."
"You could do a subscription, where you pay yearly, or you could purchase it outright. The licensing cost is based on the number of users on the system that you are monitoring."
"It's expensive, kind of, really expensive."
"I would rate the pricing an eight out of ten, with ten being the most expensive."
"The platform is expensive. I rate the pricing a nine out of ten."
"The pricing is good. It neither expensive nor cheap. It is average."
"Licensing is on an annual basis. Maintenance and renewal fees are separate. Varonis Datalert is quite expensive."
"Varonis Platform wasn't certainly the cheapest solution."
