Used to identify and monitor any vulnerabilities or issues within the attack surface
I don't have anything that I don't like, but there is a feature that IONIX can also consider. We're a heavy user of IONIX services and have a very, very good partnership. However, IONIX only looks at certain domains, particularly the external-facing perimeter. There are services in modern-day organizations that could potentially expose internal resources to the perimeter side as well, like whether your authentication to internal identities is exposed through the internet. All organizations are very concerned about that. Even big organizations like Microsoft are falling for that kind of attack. IONIX can offer additional services to detect any potential bridging of very sensitive internal resources to the external side.

Enhanced visibility and exposes vulnerabilities but needs more integration
I am currently in the pilot stage of implementing Microsoft External Attack Surface Management (EASM). My organization is transitioning to a comprehensive track of Microsoft solutions, and we will move to full-scale production in another year, maybe Microsoft External Attack Surface Management…

Quotes from Members

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

Pros

"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."
"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."
"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."
"We're constantly surprised by how good IONIX is at detecting timely vulnerabilities."
"The integration was easy."
"The most valuable feature of IONIX is the effortless setup."
"It seems to be better at protecting from cyberattacks."
"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
"Microsoft External Attack Surface Management helps improve the visibility of my exposed vulnerabilities and provides an overview of my security posture across the globe."
 

Cons

"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."
"Integrating on-premise Jira with IONIX to track changes and discussions would be highly beneficial for us in the future."
"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."
"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."
"Further integration across different Microsoft products would be an improvement."
"With Microsoft, support is always crazy, it's not easy to get support."
"The integration is not as seamless compared to competitors like Palo Alto."
 

Pricing and Cost Advice

"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."
"The solution's pricing is reasonable and at par with the rest of the industry."
