Antonio Scola - PeerSpot reviewer
Offers reliable security support and encourages a safe migration to cloud environments while there is room for better reseller collaboration
I really don't know to tell the truth because we sell many solutions and don't sell exclusively Tenable, so I'm not in a condition to give a precise definition of what could be improved. My perception is this: when customer A needs Tenable Cloud Security, we introduce and demonstrate it. They POC, they appreciate it. The solution serves in such use cases ABC. I am very pragmatic and straightforward - as long as they use or want the solution, I am interested. If they don't, my question is what are the main objections? They may discuss pricing, or they may say they thought the solution had certain technical capabilities that they could not find.

A scalable tool that needs to make its setup phase easier while improving the stability it provides
The initial setup of Tenable.io Container Security is a little bit complex. If you have a bigger cluster or container environment, then the solution's deployment phase may take more than three months since you won't directly go for the solution's block mode. To start things in the solution, you will have to deploy it in SIEM mode, while the detection mode will provide you with visibility in accordance with which you need to take actions for production, which needs time. Regarding the time taken for deployment, for detection, it may not take more than a week, but in production, it may take at least three months to be completed. For the deployment process, there are some scripts available along with some YAML files that you need to run on the cluster, specifically considering the cluster you want to focus more on before creating Tenable Cloud Security Console. After creating Tenable Cloud Security Console, you can proceed with the onboarding process.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Scanning and reporting are the most valuable features of Tenable Cloud Security"
"If you have multi-cloud tenancy using AWS and Azure, you can have a single dashboard where you can onboard all the cloud infrastructure and have visibility into it."
"The analytical and reporting capabilities are pretty straightforward and show every transaction and major attempt to attack the application in the cloud."
"Tenable Cloud Security excels in vulnerability detection, one of its strongest features. Another valuable feature is software composition analysis, which highlights and automates the detection of security flaws. Additionally, their knowledge base is excellent; if anything goes wrong, they provide clear guidance on what needs to be done to address specific vulnerabilities."
"The solution’s vulnerability management feature has helped us identify and mitigate risks well."
"The product's visibility and remediation work fine for me."
"The key benefit lies in having the largest and most up-to-date database. When it comes to using any Tenable product, it excels in finding vulnerabilities and providing analytics."
"The product's deployment phase is easy."
"The strong security provided by the product in the container environment is its most valuable feature."
"Tenable.io detects misconfiguration when you deploy a Docker or Kubernetes container. It's much better to remedy these issues during deployment instead of waiting until the container is already in the production environment."
"It is a scalable solution. Scalability-wise, it is a good solution."
"Nessus scanner is very effective for internal penetration testing."
"The solution shows you the exploitable vulnerabilities and helps you prioritize."
"The tool's most valuable feature is scanning, reporting, and troubleshooting."
"It helps us secure our applications from the build phase and identify the weaknesses from scratch."
"Currently, I haven't implemented the solution due to its deprecation by the site. However, I can highlight some benefits of Tenable Cloud Security, a cybersecurity solution with various features for scanning vulnerabilities in both cloud environments and on-premises container security."
 

Cons

"In my experience, Tenable Cloud Security is not very stable."
"Ermetic needs to improve its security scanning. I would like to see more dynamic graphical forms."
"I do think there might be room for more integrations. This could allow for further customization and flexibility, essentially offering different functionality options to accommodate various budgets."
"Due to its robust nature, the platform's adoption can be overwhelming initially. However, once organizations start using it, they tend to get used to it. I haven't had much direct interaction with the support team, but some partners have reported a desire for better support for the product."
"If Tenable Cloud Security offers a complete Cnapp solution with CWP, CIEM, and Waap security, it will be able to compete with other competitors."
"Tenable needs to offer a patch-based solution since it is an area where the tool lacks a bit."
"There is a need for the support team to improve their response time since it is one of the areas where the product's technical team has certain shortcomings."
"The product must provide more features."
"They need to work on auto-remediation so it's easier for the security team to act quickly when certain assets or resources are deployed. The latest version has a CIS benchmark that you need to meet for containers in the cloud, but more automation is needed."
"Tenable.io Container Security should improve integration modules. It should also improve stability."
"The stability and setup phase of the product are areas with shortcomings where improvements are needed."
"I feel that in certain areas this product has false positives which the company should work on. They should also try to include business logic vulnerabilities in the scanner testing. Finally, the vulnerability assessment feature should be increased to other hardware devices, apart from firewalls."
"The support is tricky to reach, so we would like better-oriented technical support enabled."
"The solution’s pricing could be improved."
"I believe integration plays a crucial role for Tenable, particularly in terms of connecting with other products and various container solutions like Docker or Kubernetes. It seems that in future updates, enhanced integration is something I would appreciate. Currently, there is integration with Docker, but when it comes to Kubernetes or other container solutions, it appears to be a challenge, especially with on-prem scanners."
"The initial setup is highly complex."
 

Pricing and Cost Advice

"The tool's price is good compared to other brands. The tool's subscription is for a year."
"The tool's pricing is fair."
"There is a need to opt for a subscription-based pricing model to use Tenable Cloud Security. I rate the product price an eight on a scale of one to ten, where one is low price and ten is high price."
"It's best to be an institutional buyer and directly contact the sales team as they can provide over-the-top discounts for bulk orders."
"I rate the tool's pricing a three out of ten."
"The solution's pricing is neither cheap nor very expensive."
"The product does not operate on a pay-per-license model."
"I rate the product’s pricing a six out of ten."
