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

"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."

"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."

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

"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."

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

"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."

"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."

"The GUI features are very good. Threat intelligence is also very good."

"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."

"The initial setup is very easy."

More Orca Security pros

"The predictive prioritization features are pretty good. They do a lot of research and we trust the research that they do internally. They have knowledge of what's going on with many companies, where we only get a view into what's going on here. So the ability to get best practices out of them as part of this solution, is valuable to us."

"Tenable also helps us to focus resources on the vulnerabilities that are most likely to be exploited. And since it is continuously updated, it allows us to reevaluate quickly if there are new vulnerabilities found..."

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

"The most valuable features in Tenable SC are scanning and analysis."

"The scans are the most valuable aspect of this solution."

"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."

"The tool's dashboard and reporting capabilities match our company's needs since we are able to modify the basic view to create a new dashboard, and it works out very well for our needs."

"Support is knowledgeable."

More Tenable Security Center pros

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."

"As with all software, the user interface can always be made simpler to use. It would be helpful for people with very little knowledge, like somebody sitting behind the SOC, to allow them to be able to drill down into things a little bit easier than it is currently."

"The main drawback in an agentless approach is that if the solution detects a virus or malware in the environment, we need to manually remove it. But from my experience with other production environments, it's not straightforward to install agents in the hope they will automatically remediate viruses, even from production environments... Ultimately, the ability to auto-remediate is something that I would like to see."

"The documentation for Orca Security could be improved."

"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."

"The timeout settings could be made more customizable, as sometimes if I leave the office early, it's still running unless manually turned off."

"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."

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

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

More Orca Security cons

"The solution needs to improve its support. I would like to see a bird's eye view of my network architecture. I would also like to see the continuous view feature in the tool."

"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"

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

"The solution is expensive."

"We would like to see the inclusion of external IPs and simplified reporting that's easier to deal with"

"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."

"The solution's user interface has some issues."

"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."

More Tenable Security Center cons

Pricing and Cost Advice

Information not available

"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."

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

"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."

"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."

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

"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."

"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."

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

More Orca Security pricing and cost advice

"Tenable is open-source."

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

"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."

"Tenable.sc is more expensive than its competitors."

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

"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."

"The pricing is more than Nexpose."

"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."

Orca makes cloud security possible for enterprises moving to and scaling in the cloud with its patented SideScanning™ technology and Unified Data Model. The Orca Cloud Security Platform delivers the world's most comprehensive coverage and visibility of risks across AWS, Azure, Google Cloud and Kubernetes.

At Orca Security, we’re on a mission to make it fast, easy, and cost effective for organizations to address critical cloud security issues so they can operate in the cloud with confidence.

Key Platform Features:

Agentless: Complete, centralized coverage of the entire cloud estate, without the need for installing and configuring agents or layering together multiple siloed tools. Full visibility of cloud misconfigurations, vulnerabilities, workload protection, malware scanning, image scanning, file integrity monitoring and more.
Asset Inventory: Get a complete inventory of all your public cloud assets, including detailed information on installed OSes, software, and applications, as well as data and network assets such as storage buckets, Virtual Private Clouds (VPCs), and Security Groups.

Risk Prioritization: Prioritize the 1% of risks that matter the most, based on impact scores. Secure the vulnerabilities and misconfigured targets (critical assets) and eliminate the potential risks residing on the attack paths to those targets.
Cloud Threat Detection: Monitor for malicious activity within your entire cloud estate. Be aware of detected threats, user behavior anomalies and more.

Breach Forensics: Log every change and all activity into a central repository for investigation procedures to confirm or deny entry and compromises within the cloud estate.
Cloud To Dev (Shift Left): Orca’s built-in shift left capabilities enables DevOps to focus more security attention earlier in the CI/CD pipelines. Security teams are able to trace a production risk (misconfiguration or vulnerability) directly to the original source code repository from which it came, even down to the exact line of code that is at the root of the identified risk.
Compliance: Choose from over 60 preconfigured compliance frameworks, cloud security best practices, CIS Benchmarks, or design and build your own compliance framework for fast and continuous reporting.
Security Score: The Orca Security Score is found on Orca’s Risk Dashboard and is updated daily. The overall score is calculated based on performance in the following five categories - Suspicious Activity, IAM, Data at Risk, Vulnerable Assets, and Responsiveness. Since the scores are percentage based and not raw numbers, you can objectively make comparisons to other organizations within your industry or business units of different sizes. In addition to reporting to senior management, the Orca Security Score can help with internal self-monitoring, as a way of measuring risk mitigation efforts, to know where to focus efforts, and track progress.
