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 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 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."

"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."

"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 most valuable feature of Orca Security is the automated scanning tool, user-friendliness, and ease of use."

"I would rate the quality of support as nine stars out of ten due to their quick and helpful responses."

"The visibility Orca provides into my environment is at the highest level... When I dropped them into the environment, from the very get-go I had more insight into the risks in my environment than I had had during the entire two and a half years I had been here."

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

"One of the valuable features of Orca Security is its design and options that allow flexible filtering and user-friendly visualization."

"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."

More Orca Security pros

"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."

"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 most valuable features of Tenable SC are the reports and the dashboards."

"Tenable SC is good for reporting and alerting. The filtering feature is also very valuable. Its integration with multiple vendors is quite good. It can be integrated with SIEM solutions and PAM solutions such as Thycotic, which is very helpful."

"Compared to other products, the most valuable features of the solution are its ease of use and ability to provide visibility over scan results while providing many templates to users, making it a helpful tool."

"Tenable SC's most valuable features are the low number of false positives and the strong capability of providing prioritization for the vulnerabilities detected."

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

"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."

"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."

"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."

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

"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."

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

"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."

"I think Orca could give me more alerts. It could give me a dashboard with all the specific types of alerts I want to see for the day. It should just be one click."

More Orca Security cons

"Current web page needs improvement, slows down processes."

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

"Support could be faster."

"Tenable SC can improve by adding more integrations with HCI-type tools and more accurate vulnerability detection."

"The solution should provide better web application features and support."

"The web application scanning area can be improved."

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

"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."

More Tenable Security Center cons

Pricing and Cost Advice

Information not available

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

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

"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."

"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."

"Its license is a bit expensive."

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

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

More Orca Security pricing and cost advice

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

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

"The tool provides competitive pricing."

"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 happy with the licensing cost and find it affordable."

"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."

"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 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."

Zafran Security

Orca Security is the pioneer of agentless cloud security that is trusted by hundreds of enterprises globally. 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.

Attack Path Analysis: Visualize attack vectors to critical assets or crown jewels. See which assets are susceptible to lateral movement, assume roles, privilege escalation, and more.

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.

Reduce MTTR and remove operational friction:

“We can’t ask developers things like ‘Did you think about security? When you start a new VM on AWS, can you please let me know so I’m able to scan it? Can you please deploy an agent on that machine for me?’ We need a better way to work. Orca provides that better way by eliminating organizational friction.” - Erwin Geirnaert, Cloud Security Architect | NG Data
