Is user-friendly, quick to install, and provides great visibility into our assets
IONIX helps us with KPIs by identifying our assets and locating publicly accessible vulnerabilities within those assets. Additionally, it provides a severity rating for each vulnerability. The tracking is important because it ensures we are not replicating efforts. IONIX prioritizes bug fixes based on severity using a scale of one to ten. This ensures that critical and high-priority issues are addressed immediately. IONIX helps us identify our most critical assets, the ones that have the biggest impact on our risk exposure. It can also pinpoint any of these assets that are externally facing, meaning accessible to anyone on the internet. This is extremely valuable because having critical assets exposed to the public internet significantly increases the risk of attack. By identifying these exposed assets and highlighting their vulnerabilities, IONIX provides a crucial service. IONIX excels at identifying risks in third-party digital supply chains. This makes it easy to leverage those KPIs and demonstrate a potential correlation between security and search engine optimization to our marketing team, thereby getting them involved. Fortunately, I haven't had to discuss any false positives. The majority of our alerts, particularly the medium-severity ones, seem to be triggered by hyperlinks to third-party websites. We have a significant number of these alerts, and I'm scheduled to meet with the marketing department to address them. The IONIX user interface is truly user-friendly. Setting up a link, and credentials, and navigating the platform was incredibly fast and required no prior configuration. Within five minutes, I was up and running, able to explore a report and initiate action from our infrastructure team. It's a remarkably fast and smooth experience. Non-technical people can see the evidence and take action based on their one-sentence actionable items. IONIX integrates with our SOC tools to automate tasks. We plan to further leverage IONIX by integrating our AWS public-facing assets and Jira ticketing system. This will allow for automated project creation for our infrastructure team. I realized the value of IONIX within the first five minutes. It identified two critical vulnerabilities that we were then able to address. The Active Protection feature automatically detects exploitable vulnerabilities in our system and takes control of them, without requiring manual intervention from us. IONIX can potentially take control of an asset before an attacker does. This would prevent the attacker from gaining access. IONIX would notify us of the issue and help us mitigate it before returning control of the asset. Ultimately, it's far better to have a trusted security provider like IONIX manage our assets than a malicious actor. The Active Protection feature is important to us for those reasons. IONIX helps us reduce our mean time to remediation by providing clear and concise information. This allows our marketing team to address certain situations without requiring IT intervention. I've accessed the IONIX threat exposure radar three times since its implementation, and thankfully, there haven't been any threats detected on any of those occasions.

Provided increased visibility across the organization's servers
The user interface of Tenable Nessus feels outdated and could be more user-friendly. Additionally, the documentation is not well-organized, which can be confusing when searching for solutions or specific information related to Tenable Nessus Professional. The reporting feature could be improved by allowing users to create their own templates instead of relying on predefined ones.

Quotes from Members

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

Pros

"We're constantly surprised by how good IONIX is at detecting timely vulnerabilities."
"My favorite is the dark web association that it does. It basically takes things that are unknown to you and then also runs those URLs through the dark web to see if there are potentially leaked credentials unknown to you. It links both of those together and gives you that on a report. You can identify potentially compromised credentials that were previously unknown to you, and you can do something about them. It is a cool feature."
"IONIX enables us to manage all our assets from one platform. We can see all the assets, login pages, web services, etc., from one place. It automatically scans everything so we can find new information about our organization. We don't need to add each asset or interface manually."
"The integration was easy."
"The portal is an excellent resource, offering valuable insights in a clear and actionable format. It provides a wealth of information, presented in a way that's easy to understand and use. This aligns perfectly with our key focus when working with IONIX: ensuring the data they deliver is highly actionable."
"The most valuable feature of IONIX is the effortless setup."
"The ease of use is the primary valuable feature. This specific version is very straightforward. I like the ability to modify it and configure it based on the different policies."
"I have found the vulnerability assessment and the reports to be useful."
"My favorite part about Nessus is that you can customize the tool to scan exactly what you want. Microsoft releases new patches monthly on Patch Tuesday, and a lot of companies track that date. I set up Nessus for the day after Patch Tuesday to see which devices have already pushed those updates from Microsoft, so we can stay updated."
"The most valuable feature of Tenable Nessus is the GUI and user-friendliness. Additionally, the environment is easy to work with."
"It gives a holistic view of your entire environment."
"The most valuable features of Tenable Nessus are the scanning option. Advanced scanning is highly useful. The offline config audits and application assessments are useful."
"The solution is great for scanning servers."
"It also has an executive report where you don't have to provide the client all the detail for them to sift though. But if they wish to dig through the detail they can."
 

Cons

"Integrating on-premise Jira with IONIX to track changes and discussions would be highly beneficial for us in the future."
"IONIX can offer additional services to detect any potential bridging of very sensitive internal resources to the external side."
"Our team is always looking for ways to improve the product. Although we understand we are not the only client, the company has been very receptive to our suggestions."
"It would be extremely beneficial if IONIX could integrate with popular SaaS services like Salesforce, Box, Zoom, or NetSuite."
"The integration and mechanisms for scanning things after we fix them could be simpler. IONIX isn't an easy product to use, but it's one of the best solutions once you learn how to work with it."
"There are a couple of opportunities for them under integrations. They only have two SIEMs. They do not have our current SIEM in there. It would be nice to have our current SIEM in there, which is Hunter's AI."
"Tenable Nessus could include a broader range of IT assets."
"We'd like to see more integration potential within the solution."
"Tenable Nessus could improve the reporting by adding some dashboards. The reports are a hassle at this time. Tenable.io has more detailed reports. Having a better dashboard that can show where the vulnerabilities are and be categorized would be helpful. We then could present them to upper management for a deep overview of our network posture which they do not see."
"EQA's and dashboards should be addressed in the next release."
"I think the reporting templates could be improved with Tenable Nessus."
"I would like to see an improvement in the ranking of high, medium and low vulnerability."
"Tenable Nessus could improve by having more steady updates which will reduce the vulnerabilities."
"It wasn't very clear how the scripts are running the scans. There's information about the script but it's not straightforward. The script information for each of the plugins should be available, but it doesn't give us straightforward direct information about how it was executed. That needs to be more clear."
 

Pricing and Cost Advice

"The solution's pricing is reasonable and at par with the rest of the industry."
"Since we were an early adopter of IONIX, I believe we have a very favorable pricing model."
"Its pricing is fair."
"The pricing is good."
"We paid about six thousand dollars per license."
"One problem with Tenable is its pricing policy. Optimal results can be achieved with Greenbone Solutions which has much more friendly pricing policies."
"The price is high for the solution. There are free tools with similar functionality available. The solution cost approximately $3,500."
"The price is okay. I would give it a seven out of ten, where one is cheap and ten is expensive."
"I think the price is fairly affordable. It provides a license that is fair."
"Nessus Manager is not an expensive product. It has its limitations, but the pricing reflects that. We have a yearly subscription."
"The solution is expensive."
"This solution is affordable."
