    All-in-One Triage with a Strong Researcher Pool That Catches What Scans Miss

    Reviewed on Sep 04, 2026
    Review provided by G2
    What do you like best about the product?
    The biggest benefit is having the entire triage process in one place; from intake and researcher back-and-forth to severity scoring. So things do not get lost. The researcher pool is strong too. They regularly find issues that our automated scans miss.
    What do you dislike about the product?
    The biggest issue is report quality. Too much triage time goes to filtering low-effort or duplicate submissions before we can focus on valid findings. The platform can also feel slow and clunky when moving between reports, programs, and analytics.
    What problems is the product solving and how is that benefiting you?
    HackerOne gives us broader vulnerability coverage than relying on internal testing and automated scanning alone. The researcher community helps uncover issues our existing tools can miss, and it’s helpful that reporting and triage stay together in a single workflow.

    Great Triage and Metrics, but Pricing Tiers and Renewals Create Friction

    Reviewed on Sep 02, 2026
    Review provided by G2
    What do you like best about the product?
    I really like the way critical and high findings are prioritized. The H1 triage analysts are extremely helpful and genuinely pleasant to work with.

    I also appreciate that the platform offers many different ways to pull metrics, which makes it easier to share clear updates with leadership on how the program is progressing.

    The researcher community is very large and includes highly talented security researchers from around the world, so it’s easy to find people who can support our program’s specific needs.

    Additionally the UI in the platform is very appealing and easy to use (especially in dark mode).
    What do you dislike about the product?
    The pricing structure (consumption tiers every 50-100K in bounty spend) is the worst part about H1. It makes running a program significantly more difficult and forces us to be very careful when paying researchers and hinders out ability to mature our program. The value that comes from a 50K different in bounty spend is not work the additional cost from the consumption tier. Switching to a unlimited tier structure would be amazing.

    The triage time historically has also been quite slow, although recently we have seen large improvements via prioritization of high impact findings.

    The support in terms of getting quotes and working with HackerOne folks also has room for improvement. It is a difficult process to work back and forth trying to get renewals/upgrade quote processed.

    HAI also hallucinates metrics all the time and will struggle to provide details on where it got the data.

    The findings tab should also have the ability to export results across all pages, not just one page at a time. This would make it much easier to generate out own metrics using data we trust.
    What problems is the product solving and how is that benefiting you?
    They provide everything we need to run our bug bounty program and helps us identify vulns that our other security tooling misses.
