Featured Reviews

Israel Cavazos Landini - PeerSpot reviewer
Weekly insights and risk analysis facilitate informed security decisions
I appreciate the weekly insights Zafran provides, which include critical topics for networks and IT security, allowing us to evaluate which insights apply to our environment. The organization score feature is valuable to keep the leadership team updated on how our infrastructure fares security-wise. The applicable risk level versus base risk level feature is beneficial because prior to Zafran, we only used the base risk level, but now understand that risk depends on the asset itself. Zafran is an excellent tool.
NitinKushwaha - PeerSpot reviewer
Stable product with an ability to build complex roles
We use Tanium as an EDR solution for managing end-user devices and servers The product is granular and can build complex roles compared to other EDR vendors. Tanium's dashboard UI could be similar to CrowdStrike. We have been using Tanium for two and a half years. The product is stable. I rate…
HarshBhardiya - PeerSpot reviewer
Provided increased visibility across the organization's servers
The user interface of Tenable Nessus feels outdated and could be more user-friendly. Additionally, the documentation is not well-organized, which can be confusing when searching for solutions or specific information related to Tenable Nessus Professional. The reporting feature could be improved by allowing users to create their own templates instead of relying on predefined ones.

Quotes from Members

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

Pros

"Zafran is an excellent tool."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"We saw benefits from Zafran Security almost immediately after deploying it."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"I like the tool's incident response and security patching."
"I'm not so familiar with the tool but I like the interaction of the console to the picture. Patching is the primary model I have been focusing on for the last couple of weeks. So I have created a proof of concept environment and have been checking the available features."
"For incident response tasks, all these tasks can get done in minutes with minimal disruption to the end-user."
"I find the inventory and compliance features of Tanium to be the most impressive."
"The product is granular and can build complex roles compared to other EDR vendors."
"Tanium's most valuable features are patch management, inventory, and distribution software."
"Tanium's most valuable feature is its instant discovery aspect."
"The solution is scalable and helps to understand how infrastructure works. It helps to improve the health of the organization."
"The plug-in text information is quite useful."
"The results are not that bad, but the key selling point is that it is an affordable tool set."
"Easy to set up vulnerability scanner with good stability and a responsive technical support team."
"Ease of reviewing scores, identifying vulnerabilities, and getting information on them."
"The most valuable feature is the breadth of vulnerabilities that it finds. It's able to find across a lot of different platforms and operating systems. It's also able to combine local testing with network-based testing."
"The stability is very good."
"The most valuable feature is how it scanned and detected through its database to let us know exactly what fixes we needed to put in place for the vulnerabilities. It detects and it also gives you the way to fix it."
"The scanning capabilities are most valuable when compared to Nessus."
 

Cons

"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"I think the ability to have some enhanced reporting capabilities is something they can improve on, as they have good reports but we have asked for some specific reporting enhancements."
"Initially, we were somewhat concerned about the scalability of Zafran due to our large asset count and the substantial amount of information we needed to process."
"It is not really additional functions, or the features that are needed, rather the complexity would be reduced based on the number of modules required to put together a comprehensive operational security and risk compliance model."
"The solution can give a lot of false positives."
"They could improve the UI."
"Most of the time, agent-relative issues have to be more equipped with self-healing features. At times, the agent is there, but for some reason, it doesn't report a status. It gives certain problems that are obviously agent-based."
"Tanium required local admin or root rights on Mac devices, which did not comply with our security policies. This made the solution less suitable for our restrictive environment."
"I would like to have more integrations and custom plugins to input. Integration is always a big deal in a lot of different environments."
"Tanium’s scalability could be improved."
"Any movement into a SaaS solution has challenges since the processes and data flows are not well defined. Hence, you need to build it at the same time."
"Tenable Nessus could improve the reporting by adding some dashboards. The reports are a hassle at this time. Tenable.io has more detailed reports. Having a better dashboard that can show where the vulnerabilities are and be categorized would be helpful. We then could present them to upper management for a deep overview of our network posture which they do not see."
"It would be better if they had application-level support for mobile devices. They don't have anything to scan mobile devices. Tenable Nessus doesn't have a mobile application vulnerability assessment. I also have issues with the false positive rates. The product has limited features."
"I think the reporting templates could be improved with Tenable Nessus."
"I would like to see an improvement in the ranking of high, medium and low vulnerability."
"Vulnerability recommendations are outdated and not in line with industry standards."
"There is room for improvement in finishing the transition to the cloud. We'd like to see them keep on improving the Tenable.io product, so that we can migrate to it entirely, instead of having to keep the Tenable.sc on-prem product."
"Tenable Nessus could improve the reporting."
"Lacks some penetration testing-related services."

"I rate the product's price seven or eight on a scale of one to ten, where one is low price and ten is high price."
"Its pricing is great and can't be improved. It is very cheap. It is less than 2,000 pounds a license, and you can't really ask for more. It has unlimited IPs and unlimited scans. There are no particular pricing constraints. The only additional cost is the inherent cost of the people to actually review the actual scans."

"Tenable Nessus is affordable."
"The product pricing is dynamic and varies based on the specific needs of each project and customer."
"The price is okay. I would give it a seven out of ten, where one is cheap and ten is expensive."
