Likelihood to Recommend	Informer No answers on this topic	Discontinued Products It's really challenging at times to contend with multiple vulnerabilities on a daily basis, and having a way to make sense of what actually needs to be prioritized and what can be shifted further down the task list is extremely helpful. Because the solution suggests what your next step should be in mitigating a specific vulnerability, it helps us save time and research by enabling us to immediately take action after being informed about an issue.

Pros	Informer No answers on this topic	Discontinued Products Identifies vulnerabilities and they are easily understood. Easy to identify remedies in an instant. Campaign feature is a true time saver Our CSM, Nino, is the best I have ever worked with! Incentivized Verified User Read full review
Cons	Informer No answers on this topic	Discontinued Products Deduping of assets could be better. The weighting of vulnerabilities is hard to describe to non technical executives. The Business Groups and Tagging needs improvement. Or at least allow tags to be removed if not needed. Now they are static from the API feed. Incentivized Verified User Read full review
Alternatives Considered	Informer No answers on this topic	Discontinued Products I wasn't here at the time when the company compared different vulnerability management platforms so I'm not sure on the reasoning and difference between the 2. It could be that the team went through different choices and found Vulcan to be the best fit. It's hard for me to say why Vulcan was specifically chosen Incentivized Verified User Read full review
Return on Investment	Informer No answers on this topic	Discontinued Products Allows much better prioritizing of which assets are most vulnerable Allow a better understanding of what assets are actually under real threat vs. what is assumed to be vulnerable, but the real world fact is the system would be hard to reach internally, so it's not as vulnerable.
