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.
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.
OndrejKOVAC - PeerSpot reviewer
Empower clients with risk-based vulnerability management through continuous workflow and valuable insights
Tenable Security Center could improve by implementing more dynamic data displays and translating reports into European languages. This is especially relevant in Central Eastern Europe, where clients often require reports in local languages. Additionally, the licensing model could be more flexible for managed security providers, similar to a pay-as-you-go model.

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."
"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"We saw benefits from Zafran Security almost immediately after deploying it."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"The solution's coordinated detection and response across devices and identities is impressive because it is complete."
"My favorite part of Microsoft Defender for Cloud is the compliance features. Defender covers a wide range of workloads, on par with competing products on the market."
"Some of the most valuable features of Microsoft Defender for Cloud include its effectiveness in threat detection through unsupervised machine learning, CTI, and advanced sandboxing."
"I would rate Microsoft Defender for Cloud a ten out of ten."
"The product has given us more insight into potential avenues for attack paths."
"The most valuable feature is the comprehensive overview across different workloads. It allows us to see protection not just across one workload, such as virtual machines, containers, infrastructure, or data, but across all our workloads. This overall visibility is really helpful."
"I would rate Microsoft Defender for Cloud a nine out of 10."
"Threat protection is comprehensive and simple."
"We use Tenable to scan all of our environments and plugins for vulnerabilities. Tenable helps us discover network vulnerabilities to threats and piracy."
"The tool gives us fewer false positives. Compared to its competitors, the solution’s reports are more accurate."
"The scanning part, the agent part – that's the valuable aspect."
"The most valuable feature is the automatic and periodic management of security scans, along with the ability to consolidate all information into a single dashboard."
"The solution is very intuitive and the dashboards are simple to use."
"The most valuable features in Tenable SC are scanning and analysis."
"The usability is really good. It's very easy to use and a good platform. It is scalable and very stable. The technical support is fine and the setup is super easy."
"It's a very useful tool."
 

Cons

"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."
"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"If they had an easier way to display all the vulnerabilities of the machines affected and remediation steps on one screen rather than having to dive deep into each of them, that would be a lot easier."
"My experience with Microsoft Defender for Cloud has been largely negative due to a poor user experience."
"The most significant areas for improvement are in the security of our identity and endpoints and the posture of the cloud environment. Better protection for our cloud users and cloud apps is always welcome."
"Microsoft Defender for Cloud is pricey, especially for Kubernetes clusters. It could be cheaper."
"The documentation and implementation guides could be improved."
"While we are satisfied with Defender for Cloud's features, an AI enhancement could potentially provide better advice and adapt more effectively to our environment."
"The product was a bit complex to set up earlier, however, it is a bit streamlined now."
"Agent features need to be improved. They support agents through Azure Arc or Workbench. Sometimes, we are not able to get correct signals from the machines on which we have installed these agents. We are not able to see how many are currently reporting to Azure Security Center, and how many are currently not reporting. For example, we have 1,000 machines, and we have enrolled 1,000 OMS agents on these machines to collect the log. When I look at the status, even though at some places, it shows that it is connected, but when I actually go and check, I'm not getting any alerts from those. There are some discrepancies on the agent, and the agent features are not up to the mark."
"The tool's initial configuration is not so easy."
"It could be more user-friendly for creating custom reports."
"Current web page needs improvement, slows down processes."
"In terms of configuration, there is some level of flexibility that we are not able to achieve."
"The vulnerability scan does not work correctly until the access privileges are set by the system administrator."
"There's a lot of information being streamed out of the reports. What would be nice, and maybe we just haven't found it, would be more of an executive-type view. We still expect it to collect all this information, but we would like a feature that would allow us to show it to an executive or a director or someone like that and give them some type of high-level overview but not get into the nitty-gritty."
"For downloading reports, we have to go to the scan and then we have to go to the reports and download the Excel or CSV or PDF. I think these menus and clicks can be minimized."
"If I want to have a very low-managed scan policy, it's a lot of work to create something which is very basic. If I use a tool like Nmap, all I have to do is download it, install it, type in the command, and it's good to go. In Security Center, I have to go through a lot of work to create a policy that's very basic."
 

Pricing and Cost Advice

Information not available
"The price of the solution is good for the features we receive and there is an additional cost for Microsoft premier support. However, some of my potential customers have found it to be expensive and have gone on to choose another solution."
"There are two different plans. We're using the secure basic plan, but we have used the end security plan as well. There are additional costs, but it gives us more functionalities compared to the basic plan."
"The pricing and licensing of Microsoft Defender for Cloud have been good for us. We appreciate the licensing approach based on employee count rather than a big enterprise license."
"The pricing model for most plans is generally good, but the cost of the new Defender for Storage plan is high and should be revisited, as it could lead to disabling desirable security features due to cost."
"The cost of the license is based on the subscriptions that you have."
"Pricing is a consideration, but we strive to keep costs low by enabling only necessary services."
"Its pricing is a little bit high in terms of Azure Security Center, but the good thing is that we don't need to maintain and deploy it. So, while the pricing is high, it is native to Azure which is why we prefer using this tool."
"Currently, Microsoft offers only one plan at the enterprise level which is $15 per machine."
"We're a Fortune 500 company... our licensing costs [are] in the seven figures."
"This solution's price is quite high."
"I rate the solution's price as seven on a scale of one to ten, where one is cheap and ten is expensive. The tool is quite expensive."
"The pricing depends upon the number of IPs."
"The price of Tenable SC is expensive, we pay approximately €70,000 for the license annually. We have to pay for each IP test. The cost of other solutions is far less, such as Nessus Professional, which is €3,000 annually."
"The price can start at €10,000 ($13,000 USD) for between 500 and 1,000 assets, and the price can climb into the millions as more assets are added."
"It is slightly more expensive than other solutions in the same sphere."
"Tenable is open-source."
