Has become an indispensable tool in our cybersecurity arsenal
While Zafran Security is already a powerful tool, there are areas where it could be further improved to provide even greater value. One key area for enhancement is the searching capabilities within its vulnerabilities module. By incorporating the ability to create Boolean searches, users would gain the ability to apply more complex filters and customize their search criteria. This would greatly enhance the precision and efficiency with which security teams can identify and prioritize vulnerabilities. Having such tailored search capabilities would save time and resources by narrowing down vast lists of vulnerabilities to those that meet specific parameters relevant to our unique risk environment. Additionally, integrating more robust reporting and visualization tools would be advantageous. Enhanced dashboards that offer customizable visual representations of risk configurations and threat landscapes would facilitate better communication with stakeholders, making it easier to explain vulnerabilities and the rationale behind certain security measures. This would also aid in demonstrating the improvements and value derived from existing security investments to leadership and non-technical team members.

Cloud security has improved visibility and automated deep risk investigations across clients
Identifying areas in Orca Security that have room for improvement is challenging, as there are multiple considerations including price, customization, AI, UI, and factors that could make it better or easier to use. I must consult with someone in the field because I cannot provide this information at this time since I am not operating the solution directly. What would make it a ten for me as an integrator is difficult to determine. I believe they need more time developing this solution, which means they need to be more comprehensive and extended in their approach. I think this represents the opinion of the majority.

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

"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 is an excellent tool."
"With Zafran Security, it integrates with your security controls, allowing you to take that risk score and reduce it based on the controls in place or increase the risk based on different factors, such as if the issue is internet reachable or if there's an exploit in the wild."
"We saw benefits from Zafran Security almost immediately after deploying it."
"Zafran has become an indispensable tool in our cybersecurity arsenal."
"We are able to see the real risk of a vulnerability on our environment with our security tools."
"It's for protection. It's an agentless tool. We don't need to install anything at a customer's premises. We can just scan the entire assets in the cloud."
"Orca's dashboard is excellent. My team needs to be able to focus on specific areas for improvement in our cloud environment. And most recently, we've started to get good use out of sonar, the search capabilities, and the alert creation."
"The product itself is really good. It helped us streamline the way we access our servers."
"In our opinion, Orca Sensor is the best solution available at the moment, and it significantly affects the visibility and protection of environments."
"The best features of Orca Security include its ability to perform a lot of security controls without requiring any installation of agents, making it very easy to set up."
"Orca's platform provides an agentless data collection facility that collects information directly from the cloud using APIs, with zero impact on performance."
"Orca Security has updated its interface, making it more user-friendly. I find it particularly useful as it allows me to easily navigate the dashboard and prioritize actions based on severity and criticality."
"Orca Security has helped reduce the time it takes to address cloud security alerts."
"Tenable Security Center is a relatively very good solution, and I don't think it needs improvement; it's a perfect solution."
"The scans are the most valuable aspect of this solution."
"Very customizable with a lot of templates."
"Feature-wise, Tenable Security Center is a very fast tool with many dashboards and reports, and it covers all our systems."
"The tool gives us fewer false positives. Compared to its competitors, the solution’s reports are more accurate."
"The feature we've liked most recently was being able to take the YARA rules from FireEye and put them into Tenable's scan for the most recent SolarWinds exploit. That was really useful."
"Tenable Security Center's centralized platform helped with risk assessment and management across our IT environments, covering the patching process and providing detailed reports that significantly supported our reporting and audits and helped us close audit issues safely and successfully."
"The product is our second solution, and we are happy that it meets our requirements."
 

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."
"The dashboarding and reporting functionality of Zafran Security is an area that definitely could use some improvements."
"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's not all clouds that they are currently onboarded with. For instance, they are not yet with public cloud and many other private clouds."
"The presentation of the data in the dashboard is a little bit chaotic."
"The documentation for Orca Security could be improved."
"I would like to see better customization options for security frameworks and better integration with reporting tools like Power BI or Grafana dashboards."
"I would be happy if they offered more automatic remediation options. They're working on that, but the more the better. For example, if they want you to harden a server, they would offer a hardening script that would be more aware of what's going on."
"Orca Security could improve its ticket creation process. Currently, it allows for creating tickets in only one bucket, which requires monitoring to redirect tickets to the appropriate team."
"The solution could improve by making the dashboards more elaborative and more descriptive."
"They can expand a little bit in anti-malware detection. While we have pretty good confidence that it's going to detect some of the static malware, some of the detections are heuristics. There could be a growth in the library from where they're pulling their information, but we don't get a lot of those alerts based on the design of our products. In general, that might be an area that needs to be filled since they offer it as a service within it."
"Certain aspects require manual effort, such as exporting and analyzing data for our dashboards. The built-in components of the Tenable solution are somewhat clumsy that require external tools. So, this is an area of improvement."
"There is not much room for improvement. However, there should be a guide that describes the step-by-step procedures for doing tasks. Otherwise, training is required from a senior guy to a junior guy."
"Current web page needs improvement, slows down processes."
"The reporting side can be improved. The dashboards are nice, but exporting things out for reports for management was a little tough."
"The solution is expensive."
"Tenable SC can improve by making it easier to create complicated reports and have more effectiveness in the remediation area for comparison between the scans."
"At times we have had the typical bugs."
"Deploying Tenable.sc is highly complex because it's an on-prem solution, whereas Tenable.io is cloud-based, so you can go live as soon as you log in. Tenable.sc involves significant integration with other on-prem solutions, and the deployment takes about two to three weeks with the help of a system integrator"
 

Pricing and Cost Advice

Information not available
"Overall, the pricing is reasonable and the discounts have been acceptable."
"The price is a bit expensive for smaller organizations."
"We have a total of 25 licenses for this solution. The solution is on a pay-and-you-use model."
"Orca Security charges are based on cloud workloads. So, it's based on workloads. If we look at one feature, it might be expensive."
"While it's competitive with Palo Alto Prisma, I think Orca's list price is very high. I would advise Orca to lower it because, at that price, I might consider alternatives like Wiz, which also offers agentless services."
"Orca is very competitive when compared to the alternatives and is not the most expensive in the market, that's for sure."
"The pricing depends on how many assets you have running in your cloud and how many environments you have. If you have a dev environment, test environment, and a production environment then it's really important that you have coverage for all of them."
"Orca Security is cheaper compared to other solutions in the same space."
"It is a bit expensive. Everything is included in the license."
"The licensing costs for this solution are approximately $100,000 US, and I think that covers everything."
"Tenable is open-source."
"Tenable.sc is more expensive than its competitors."
"This solution's price is quite high."
"We're able to save because we don't have to employ more staff members to help wit ht he scheduling of the scans, running the reports or sending them out to the systems owners. That alone is a big ROI for us."
"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."
"We pay around 60,000 on a yearly basis."
