All of its features are valuable but the support needs improvement
It is multiple identity and access management, so all of the applications are valuable. It's also part of the automated process The support needs improvement.  I have been using IBM Cloud Identity Service for the last five years.  It is stable.  It is scalable.  We have 5,000 users using this…
Ondrej Kováč - PeerSpot reviewer
Has vulnerability detection, software composition analysis and asset management features
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. Another area needing improvement is the implementation complexity, especially in multi-cloud environments. Tenable Cloud Security's features mean there's a steep learning curve, which can consume significant time and resources to utilize the platform's potential and fully see immediate benefits. It's similar to AI in that you must spend time fine-tuning and training before it truly helps.

Quotes from Members

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

Pros

"One of the most valuable features of IBM Cloud Identity Service is that it delivers integrations with the commercial SaaS software that's available."
"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."
"The product's visibility and remediation work fine for me."
"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."
"The product's deployment phase is easy."
"The solution’s vulnerability management feature has helped us identify and mitigate risks well."
"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 tool alerts us on depreciating performance or deficiencies of our web application. It helps us react on time."
"Scanning and reporting are the most valuable features of Tenable Cloud Security"
 

Cons

"The initial setup is complex, it's not straightforward. It takes months because it's not straightforward."
"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."
"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."
"If Tenable Cloud Security offers a complete Cnapp solution with CWP, CIEM, and Waap security, it will be able to compete with other competitors."
"The product must provide more features."
"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."
"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."
"Tenable needs to offer a patch-based solution since it is an area where the tool lacks a bit."
"I have faced several bug incidents with the solution"
"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."
 

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."
