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.

Consolidating security tools with comprehensive cloud visibility

The documentation for Orca Security could be improved. The compliance framework also needs enhancements, especially concerning integrations with other tools like ServiceNow's vulnerability modules, which are not as mature as expected. It should also increase its capability to ingest data from other security tools like CloudSight for endpoint detection and provide real-time monitoring.

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

"We saw benefits from Zafran Security almost immediately after deploying it."

"Zafran is an excellent tool."

"We are able to see the real risk of a vulnerability on our environment with our security tools."

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

"Overall, we have seen about eighty-seven percent reduction of the number of vulnerabilities that require urgency to remediate, specifically the number of criticals."

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

"The reporting and automated remediation capabilities are valuable to me. They're real game-changers."

"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."

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

"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."

"The initial setup is very easy."

"Orca provides X-ray vision into everything within the cloud properties, whereas normally, this would require multiple 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."

More Orca Security pros

"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."

"What is useful to me is being able to fulfill very customized scanning policies. In the clinical environment, because of vendor control, we can't perform credential-vulnerability scanning. And network scans, which I've done before, can cause a lot of impact. Being able to create very customized policies to be able to routinely scan and audit our clinical networks, while simultaneously not causing impact, is important to us."

"The most important features are the dashboard and reporting. The dashboard provides statistics with graphs and bar charts for our management."

"The customer service and support team at Tenable were extremely helpful."

"The tool gives us fewer false positives. Compared to its competitors, the solution’s reports are more accurate."

"It's a very useful tool."

"Initial setup was pretty straightforward."

"I think that this is a good solution for evaluating vulnerability in the network."

More Tenable Security Center pros

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."

"There were a couple of times when Orca was down when I was trying to access it. I work strange hours because all of my team is in the UK right now. It was 2 a.m. on a Saturday and I was trying to log in but it wasn't working. But relative to my other security tools, Orca is definitely the most stable that I've seen."

"A notable limitation with Orca Security is its scanning feature. 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."

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

"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."

"Another improvement would be that, in addition to focusing on endpoint compliance, they would focus on general compliance."

"The solution could improve by making the dashboards more elaborative and more descriptive."

"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 would like to see better customization options for security frameworks and better integration with reporting tools like Power BI or Grafana dashboards."

More Orca Security cons

"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."

"Tenable.sc's user interface could be improved."

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

"Its reporting can be improved. It is not easy to generate a scan report the way we want. The data is okay, but we can't easily change the template to make it look the way we want."

"Tenable's reporting engine needs improvement. It needs to be more efficient and add more features."

"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."

"The reporting side can be improved. The dashboards are nice, but exporting things out for reports for management was a little tough."

"The solution needs to improve the vulnerability assessment because we have experienced some challenges with accuracy."

More Tenable Security Center cons

Pricing and Cost Advice

Information not available

"Orca Security charges are based on cloud workloads. So, it's based on workloads. If we look at one feature, it might be expensive."

"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."

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

"Orca Security is cheaper compared to other solutions in the same space."

"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."

"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."

More Orca Security pricing and cost advice

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

"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."

"Compared to other companies or other products it could maybe be a little bit less, but the price is okay. I would say it's not very expensive."

"The licensing costs for this solution are approximately $100,000 US, and I think that covers everything."

"The tool costs around 15,000 Saudi riyals monthly."

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

"Though reasonable, the main competitor of Tenable SC, Rapid7, offers a more aggressive and better priced product."
