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.

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

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

"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."

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

"OpenNebula has very good integration with SAP Storage, is easy to use, has a good UI, and is very scalable."

"It makes maintenance very easy and stress-free for our teams."

"It has enabled us to decrease the optics by around 55 to 60%."

"It is quite easy to deploy."

More OpenNebula pros

"Agentless scanning is a possible use with Rapid7 InsightCloudSec."

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

"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."

"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."

"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."

"I can confirm money and time savings with Rapid7 InsightCloudSec, as we can scan the entire IP range simultaneously instead of manually checking each asset for vulnerabilities, reducing the need for technicians to move around the organization and thus saving significant time."

More Rapid7 InsightCloudSec pros

Cons

"They should add more features like object storage."

"There are no payment gateways in OpenNebula."

"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."

"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."

"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."

"The web interface could be better. It's not very difficult to use, but there's room for enhancement."

"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."

"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."

More OpenNebula cons

"A couple of modules are missing when compared to other providers, specifically related to some IAM, and the login piece needs improvement."

"I would say that because Rapid7 InsightCloudSec does not have automatic patching capabilities, it provides recommendations, but it does not execute anything from within Rapid7 InsightCloudSec."

"The login piece needs improvement."

"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."

"The tool needs to improve its documentation."

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

"I'm not impressed with their support right now. Their support model is not really good."

More Rapid7 InsightCloudSec cons

Pricing and Cost Advice

"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."

"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."

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

"OpenNebula gives good value for money."

"The solution is open source so is free."

"VRA is very expensive but OpenNebula is free."

"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."
