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."

"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."

"Zafran has become an indispensable tool in our cybersecurity arsenal."

"Zafran is an excellent tool."

"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."

"Another valuable feature with Orca, something that's not talked about enough, is its ability to rank your gaps and your tasks... You can get visibility with agents and there are a lot of ways to do that. But the ranking and the context across the entire environment, that is what is unique about Orca."

"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 patented technologies. It's an agentless solution, so you don't need to install an agent. Instead, it contacts your account provider and fetches metadata, eliminating the need for snapshots or reserved space to copy client infrastructure."

"Orca's SideScanning is the biggest feature. It's the 'wow' factor... With Orca's SideScanning, they just need permissions for your account and that makes it so simple."

"Orca Security has helped reduce the time it takes to address cloud security alerts."

"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."

"There are so many valuable features that I could list, but one that I appreciate is the PCI DSS compliance report."

"The product itself is really good. It helped us streamline the way we access our servers."

More Orca Security pros

"Tenable's most valuable features are the credential scan, vulnerability reports, and vulnerability ratings (VPR)."

"One of the most valuable features is their distributed scan model for allotting engines to work together as a pool and handle multiple scans at once, across multiple environments. Automatic scanning distribution is a distinguishing feature of their toolset."

"It's a very useful tool."

"Feature-wise, Tenable Security Center is a very fast tool with many dashboards and reports, and it covers all our systems."

"Compliance and vulnerability scans are most valuable. Compliance scan helps in validating how our teams are complying, and vulnerability scan helps in future-proofing. Its vulnerability detection is accurate."

"We really love the Security Center dashboard. It basically performs vulnerability scanning and then outputs a vulnerability data."

"Their overall cost of service is pretty good."

"The Auto-Remediate feature is good."

More Tenable Security Center pros

Cons

"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."

"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."

"We are PCI DSS compliant, so we need to scan our environment externally with tools vetted by the PCI DSS organization. Orca doesn't scan the environment externally. It only scans what's currently in the cloud."

"I believe they need more time developing this solution, which means they need to be more comprehensive and extended in their approach."

"In the future, I'd like to see Orca work better with third-party vendors. Specifically, being able to provide sanitized results from third parties."

"Orca needs improvement in snoozing or dismissing specific alarms."

"The automatic scan only runs every 24 hours, and if an alert is remediated within an hour, it still remains until the next scheduled scan."

"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."

"The interface can be a bit cranky and sometimes takes a lot of time to load."

"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."

More Orca Security cons

"The product should provide risk-based vulnerability management."

"Tenable SC could improve by making the creation of the initial reports easier that correspond to our network."

"We experienced some difficulties with the solution’s support."

"Tenable SC could be improved with additional connectivity to external company postures and the capability of managing and sustaining agents in the systems directly without additional platforms in the middle."

"The solution is expensive."

"The pricing is reasonable, but this could be brought down more aggressively, such as we see with Rapid7, Tenable SC's main competitor."

"It's good at creating information, it's good creating dashboards, it's good at creating reports, but if you want to take that reporting metadata and put it into another tool, that is a little bit lacking."

"The product could be user-friendly, and they could enhance the web application's security features."

Pricing and Cost Advice

Information not available

"The price is a bit expensive for smaller organizations."

"The most expensive solution is Palo Alto. They claim to be very robust. The next most expensive is Wiz, followed by Orca and all the rest."

"We have a total of 25 licenses for this solution. The solution is on a pay-and-you-use model."

"It is the cost of the visibility that you get. When you really sit down and think about what do you need to do to secure an environment with a low impact on the business, and you take a look out into the world, I think this tool is well justified around cost."

"Overall, the pricing is reasonable and the discounts have been acceptable."

"Orca is very competitive when compared to the alternatives and is not the most expensive in the market, that's for sure."

"I think their pricing model is aligned with market demand. Of course, Orca could probably better align their pricing model with the needs of smaller businesses as well as some larger-scale enterprises with millions of assets. But in all fairness, I think the Orca sales team has been accommodating and ensured that we're happy with the pricing."

"Its license is a bit expensive."

More Orca Security pricing and cost advice

"Tenable SC is priced per asset, with the basic solution starting around US$12,000 for 500 assets."

"It is slightly more expensive than other solutions in the same sphere."

"We're happy with the licensing cost and find it affordable."

"It is a bit expensive. Everything is included in the license."

"I use a local license to perform penetration testing and I'm pretty happy with everything when it comes to pricing and licensing."

"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."

"This solution's price is quite high."

"I would rate the pricing a nine out of ten, where ten is expensive. It is the most expensive tool my company is using."
