Excellent support, beneficial integration, and low maintenance
I have found IBM Cloud Identity Service to be highly scalable. It can handle thousands of users. IBM solutions are truly enterprise-grade. You don't find a lot of use cases for small businesses, or even sometimes medium businesses, the price point does not fit smaller businesses. The implementation effort, it's hard to find that cost-benefit.
DragosCernat - PeerSpot reviewer
Has significantly improved proactive monitoring through automated asset discovery and seamless integration with cloud environments
Making the system smarter would be beneficial. Adding modules for integration with AWS and Azure would be helpful. Adding capabilities for the scanner to automatically pick up changes and add assets automatically would be valuable. When discussing a big company, it is mandatory to have tools that will assist us rather than waiting for manual input to add hosts. Adding assets manually is prone to mistakes. Humans might forget to add an asset or make errors when adding multiple assets. Taking the human element out of the context and making it more streamlined is the future for security. The human should be involved where expertise is needed, such as analysis and decision-making. Currently, with resource constraints, we need tools to collect and aggregate data, eliminate false positives as much as possible, and present relevant information to employees for action.

Quotes from Members

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

Pros

"It is stable. We can automate many of our daily operations with it, and we don't have to manage many things manually."
"It is multiple identity and access management, so all of the applications are valuable. It's also part of the automated process."
"One of the most valuable features of IBM Cloud Identity Service is that it delivers integrations with the commercial SaaS software that's available."
"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."
"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."
"Scanning and reporting are the most valuable features of Tenable Cloud Security"
"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)."
"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."
"Element is precisely what we needed for close to real-time external surface monitoring, and the automatic integration capabilities, particularly with DNS, Azure, and AWS, are extremely valuable."
 

Cons

"IBM Cloud Identity Service is going in the right direction with the product. They need to keep building out the integrations and having the library is very critical."
"The initial setup is complex, it's not straightforward. It takes months because it's not straightforward."
"Everything can be more stable and secure. There could also be more account features. I would like to be able to do more things through it to manage users' accounts."
"I didn't find anything that wasn't useful or needed to be added."
"Ermetic needs to improve its security scanning. I would like to see more dynamic graphical forms."
"I have faced several bug incidents with the solution"
"Tenable needs to offer a patch-based solution since it is an area where the tool lacks a bit."
"We still maintain Tenable Cloud Security but have reduced the number of licenses. We now use it occasionally to validate specific items rather than monitoring the entire surface, for which we use Element."
"If Tenable Cloud Security offers a complete Cnapp solution with CWP, CIEM, and Waap security, it will be able to compete with other competitors."
"In my experience, Tenable Cloud Security is not very stable."
"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."
 

Pricing and Cost Advice

"The price of the solution is expensive for non-enterprise companies. IBM's always going to be a little more expensive, you're going to be paying a premium. However, depending on the organization's needs, there's probably a benefit there to do even with the price being the way it is."
"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."
