Automated access reviews have improved least privilege and simplified identity governance
The best features Opal offers are automated access reviews, centralized visibility, and just-in-time access. I especially appreciate the ability to enforce time-bound access and automatically revoke privileges, which makes least privilege management much more practical. The automated access reviews have made the process much more efficient by giving us a structured way to review and revoke unnecessary permissions. Instead of manually checking every entitlement, we can focus on exceptions and higher risk access, which makes the review process more manageable and consistent. I would also add that the context Opal provides during access reviews is valuable. You can see the access relationship and risk rather than simply approving or denying it blindly. This makes the decisions more informed and gives the team a much better audit trail.

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

"The clearest outcome I have seen is less manual effort during access reviews and better control over unnecessary or standing access, which improves the overall security posture."
"Previously, my phone usage was around nine hours and fifteen minutes or more, but it has significantly reduced to around six hours and thirty minutes to seven hours, meaning two and a half to three hours has been reduced after using Opal as my primary screen time blocker."
"Opal has positively impacted my organization by reducing stress and increasing effectiveness for all our employees; it works better so all our employees have more time to sleep and they can investigate more."
"The analytical and reporting capabilities are pretty straightforward and show every transaction and major attempt to attack the application in the cloud."
"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."
"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."
"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."
"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."
"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."
 

Cons

"Opal can be improved in some ways."
"The core platform is already strong, but I would appreciate more flexibility in customizing workflows and access review policies."
"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."
"Tenable needs to offer a patch-based solution since it is an area where the tool lacks a bit."
"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."
"I have faced several bug incidents with the solution"
"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."
"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."
"Ermetic needs to improve its security scanning. I would like to see more dynamic graphical forms."
