Reliable, simple to manage, and offers great technical support

The support of VXLAN fits with our network management. Thanks to this we can propose mixed solutions using virtual resources on OpenNebula and bare metal servers hosted in our facilities linked to each other on the sale network. This use case is very useful when some applications need bare metal power (Kubernetes workers, huge databases, AI models computations, et cetera). The cluster management is very useful for splitting our different clusters (mutual vs dedicated). We can manage deployments and capacity planning without pain. The API is also really simple and it helped us to develop the Terraform provider to manage OpenNebula like any other cloud infrastructure.

Arun Babu

SOC analyst at a media company with 1,001-5,000 employees

Daily endpoint monitoring has improved investigations and saved time but detection rules still need tuning

It is important to note that Rapid7 InsightCloudSec's features are not 100% precise, but I find about 70% of the time it is satisfactory. I would like to suggest that you improve it to be more precise, ideally making it 100% if possible. Some cases in Rapid7 InsightCloudSec indicate that the log is not enough, as they mostly just generate alerts, and the synchronization between data connectors is often problematic, particularly in terms of not being in sync always, especially between the AD and Rapid7 alerts, which generates numerous false positives. Additionally, the traditional rules should be updated, as this is a main point worth mentioning since we spend a lot of time fine-tuning these traditional rules. I suggest improving the legacy detection rules. If there are any authentication cases, such as impossible travel activity where a user has their SharePoint hosted in a different location, Rapid7 can often trigger alerts, creating confusion as we cannot fine-tune it properly. Another issue is with honeypot access. We sometimes lack necessary logs because Defender's advanced threat protection scanning gets detected as honeypot activity by Rapid7, leading to annoying and noisy alerts that we need to constantly close. If you can improve the traditional detection rules to reflect current detection rules, it would make it significantly easier for us to manage, as we constantly need to check legacy rules to update or possibly turn them off. Updating the legacy rules should be a priority.

Quotes from Members

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

Pros

"I also like the ability to build custom functions. I can define a function where I have two types of views and configure the dependencies. The virtual data centers concept allows me to define users. If a user wants to join certain kinds of machines, the host and the other user won't see them. It gives me the flexibility to define multiple views and data centers in one place."

"The service feature appeals most to us, thus it is the most valuable."

"The most valuable feature of OpenNebula is that it scales very well."

"It is quite easy to deploy."

"With a single click, we could set things up and initiate them."

"OpenNebula is lightweight, stable, and easy to customize."

"What's best about OpenNebula that people like is that it's easy to deploy. It's also easy to manage. It's interesting because people choose OpenNebula over other solutions because of the ease of management."

"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."

More OpenNebula pros

"Rapid7 InsightCloudSec has helped us save thirty percent time in our log retrievals, and it completely changed log searching, making it really fast when we search for logs, with no prior knowledge required."

"Rapid7 InsightCloudSec impacts the organization positively by acting as a shield against hackers and ransomware, providing effective protection to data and infrastructure."

"The fastest scanning is the best feature Rapid7 InsightCloudSec offers, helping me respond to threats quickly in my daily operations."

"ICSE is cheaper compared to other tools and has a pleasant user experience with good support."

"It runs every hour and has been reliable since I started."

"The tool provides centralized visibility through dashboards and alerts, allowing customers to receive reports on cloud vulnerabilities and security posture. Rapid7 InsightCloudSec provides customers with a robust understanding of cloud security."

"The best features Rapid7 InsightCloudSec offers include more automation remediation, compliance reporting for auditing, improvement on multi-cloud governance, and cost visibility, which really stand out to me."

"Since implementing Rapid7 InsightCloudSec, manual cloud security checks have been reduced by around forty to fifty percent, and mean time to resolve misconfigurations has dropped from several hours to under thirty minutes on average, significantly improving efficiency and client confidence."

More Rapid7 InsightCloudSec pros

Cons

"They have been saying for the past two and a half years that they would develop a feature to hot-add RAM and CPU, but it does not work."

"The front-facing API can be improved to support lots of requests when the platform is huge with lots of virtual resources."

"It should have a simple REST API like most other tools. It's the industry standard format. An XML-RPC API gives you an XML document that you have to convert and then do something with that. REST API endpoint provides outputs in a JSON document. I would also like to see support for user data or heat templates, which OpenStack offers, but OpenNebula doesn't have this yet."

"The UI, monitoring, and alerting could benefit from further improvements."

"Most of the competitors are offering some sort of billing software to transform their installation to work as a small-sized public cloud, but those offerings from OpenNebula are still missing."

"The storage feature that they have is a bit confusing."

"They should add more features like object storage."

"Backup features are only available in the enterprise edition. The community version lacks a good solution for making backups."

More OpenNebula cons

"Technical support could be better. It could also be easier, more user-friendly, and intuitive. The API keys aren't easy to understand, and the cloud layouts aren't intuitive and user-friendly. We should be able to integrate IM governance and APIs into non-compliant workloads like legacy solutions."

"The tool needs to improve its documentation."

"The platform could be improved with more customizable dashboards and reporting."

"Improvements could include providing better human-readable report formats with thorough explanations of CVEs and threats, detailing what can be done to eliminate malicious activities."

"Rapid7 InsightCloudSec could be better at showing dashboards for virtual firewalls and appliances. Compared to other solutions like Palo Alto, this area is not as good. So, they should work on improving this for virtual devices."

"They didn't have any documentation on how to patch it."

"There are a lot of other solutions in the market, not only providing the features of a CSPM, but also CNAPP."

"Rapid7 InsightCloudSec can be improved by seeing reductions and improvements in prioritization, tuning findings, suppressing low-value alerts, and better prioritizing the most critical risks."

More Rapid7 InsightCloudSec cons

Pricing and Cost Advice

"The licensing for OpenNebula used to be free, but now it's no longer free. A customer contacted me asking to move to another provider because of the changes in the licensing terms for OpenNebula. I have no information on how much the OpenNebula license is because the customer pays for it, and I only do the integration."

"The solution is open source so is free."

"We use the Community Edition, rather than the Enterprise Edition."

"OpenNebuoa has recently come up with a new subscription model that is economical and a lot of new customers are choosing this as it is an easy subscription model."

"VRA is very expensive but OpenNebula is free."

"OpenNebula gives good value for money."

"Companies generally buy this tool because the pricing is not that high."

"We're doing an annual subscription. There are additional expenses, but not within the confines of this platform."
