Featured Reviews

Corrado Vigano - PeerSpot reviewer
Solution integrates well with existing systems while being easy to use
The fact that it is quite integrated into the entire Microsoft environment makes it quite easy to use. Furthermore, Microsoft's reliability in providing a clear roadmap for the solution is very important, especially at a time when cybersecurity is a risk in every company. The solution is easy to reuse and not difficult to find expertise for in the market because it is widespread. It is gaining attention even from partners and from the market on the offering side. This serves as a good starting point for customers who can develop internal competence on the solution. Additionally, the presence of reliable partners who know the solution and can provide internal knowledge is the best aspect for them.
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.

Pros

"The most valuable feature for me is the firewall capabilities."
"The best features of Microsoft Entra External ID include its unification of B2C functionality and B2E features."
"It's quite easy to manage and monitor."
"The fact that it is quite integrated into the entire Microsoft environment makes it quite easy to use."
"The most beneficial feature for us is the ease of setup. With about five clicks, we can generate unique IDs and keys and set up in less than 30 minutes. We can also generate these for multiple years simultaneously, which is convenient."
"I have not encountered any stability issues with Microsoft Entra External ID."
"The single sign-on access is the most useful feature we use."
"The positive impact of Microsoft Entra External ID on my organization is that it enhances ease of use for the administrative side."
"The product's visibility and remediation work fine for me."
"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 analytical and reporting capabilities are pretty straightforward and show every transaction and major attempt to attack the application in the cloud."
"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 product's deployment phase is easy."
"The tool alerts us on depreciating performance or deficiencies of our web application. It helps us react on time."
"Ermetic can provide super visibility for our cloud environment (we are using AWS)."
"Scanning and reporting are the most valuable features of Tenable Cloud Security"
 

Cons

"Technical support needs improvement."
"Single sign-on for external applications such as Oracle could be improved to be a little bit cheaper."
"The problem with Microsoft products is that they often cater to enterprise-level needs, which can be too costly for medium-sized businesses."
"The training generally is complicated to understand, leading us to often go through a managed service provider."
"The quality of Microsoft customer support varies. With an enterprise contract, good resources are usually provided, especially in regions like Saudi Arabia or UAE. However, we have faced challenges with support quality, especially in some subcontinent areas where the resources might not be as experienced."
"The support engineers are not as skilled as our engineers. When they say something would not work, or there is no solution, we usually hear that Microsoft would not support this."
"There is room for improvement in AI technology for Microsoft Entra External ID, particularly in providing detailed alerts."
"I would like to see faster synchronization."
"Ermetic needs to improve its security scanning. I would like to see more dynamic graphical forms."
"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."
"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."
"The product must provide more features."
"I have faced several bug incidents with the solution"
"I didn't find anything that wasn't useful or needed to be added."
"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."
"If Tenable Cloud Security offers a complete Cnapp solution with CWP, CIEM, and Waap security, it will be able to compete with other competitors."
 

Pricing and Cost Advice

"We don't pay separately for Microsoft Entra External ID as it's part of our Microsoft Exchange subscription."
"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."
"The tool's pricing is fair."
"The tool's price is good compared to other brands. The tool's subscription is for a year."
