    Tenable Attack Surface Management simplifies not just your vulnerability management needs but also the mapping and discovery of known and unknown internet assets. All this within a very intuitive online dashboard, making it relatively easy to setup and configure. Without having to spend hours of training time in order to use basic functions.

    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.

    • 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.

    Very fast and helpful support staff. From the Vendor as well as the local Distributor. Support like that makes adding such a product to our MSSP offering the obvious choice.

    We didn't test any other solutions. Because to be frank no other solution can compare feature-wise as well as ease of use. Which makes reselling and supporting any Tenable product such an obvious choice for us.

    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

    • This solution is most definitely a great Return on Investment because it can quickly and accurately discover and report on our clients' entire Internet facing real estate. And keep this data updated with any changes.

    • 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.
