Easy-to-Run Pen Tests and High-Value Bug Bounties with H1
Reviewed on Sep 29, 2026
Review provided by G2
What do you like best about the product?
Over the last year, we’ve run a few different programs with H1. One of those was a penetration test to validate new security controls for our login interface. The pen test program was easy to set up, straightforward to pay for, and it was simple to communicate with the researchers assigned to the engagement.
We also get a lot of value from our bug bounty program, which helps us surface some of our most critical, previously overlooked vulnerabilities.
We also get a lot of value from our bug bounty program, which helps us surface some of our most critical, previously overlooked vulnerabilities.
What do you dislike about the product?
The interface can be confusing at times, depending on which program you’re viewing. Until recently, my biggest frustration with the H1 platform was the billing structure around system tiers and committed spend for paying out vulnerabilities. Even if we went just one dollar over, we would have been forced to upgrade to the next tier. On top of that, we couldn’t integrate our SIEM with hackerone because we didn’t have the enterprise tier. This has since been addressed with the new billing plan.
What problems is the product solving and how is that benefiting you?
H1 is an extension of the subject-matter expertise within our organization. We can only protect ourselves from what we already know, and HackerOne helps us identify and better understand the unknowns. The initial triage that HackerOne performs before we validate an issue has been extremely helpful for determining whether a report is legitimate.

Intuitive Day-to-Day Use with Strong Triage Tools and a Well-Documented API
Reviewed on Sep 29, 2026
Review provided by G2
What do you like best about the product?
My day-to-day experience using it is good and intuitive. They offer a lot of tools that help with triage, and the API is very good and very well documented.
What do you dislike about the product?
In some cases, the way the organization and the program are presented can be quite confusing, but overall it’s all good.
What problems is the product solving and how is that benefiting you?
Well, obviously it detects things that our internal team didn’t see, and it helps our H1 triage team review issues as an extra pair of eyes.

Smooth, Streamlined UI for Receiving, Reviewing, and Awarding Reports
Reviewed on Sep 28, 2026
Review provided by G2
What do you like best about the product?
The UI workflow for receiving, reviewing, triaging, and awarding reports is great and runs smoothly.
What do you dislike about the product?
The multi-program management workflow feels weak. It lacks bulk actions and program-scoped automation, which makes managing multiple programs more difficult than it should be.
What problems is the product solving and how is that benefiting you?
A vulnerability inbox for external researchers who want to securely report sensitive information.

A Solid Platform for Bug Bounty Programs
Reviewed on Sep 25, 2026
Review provided by G2
What do you like best about the product?
The best part for me is how much operational effort the platform takes off our plate. Having access to a large and skilled pool of researchers, combined with reliable triage, means we receive findings that are relevant and actionable. The relationship with the HackerOne team also stands out, especially Andrea Griffin, who consistently goes above and beyond to support us and make sure the program keeps evolving.
What do you dislike about the product?
If I had to point out one thing, it would be the occasional delays in triage. Still, it's fair to say this reflects a broader trend across bug bounty platforms, with the surge of AI-assisted submissions putting pressure on every triage team. I'm confident HackerOne is aware of it, and any improvements in how these reports are filtered and prioritized would make a real difference for us.
What problems is the product solving and how is that benefiting you?
The platform addresses a key challenge for us: keeping our applications under constant, real-world security testing without having to scale the internal team at the same pace. By connecting us with skilled researchers and handling triage and program management, HackerOne lets us find and fix vulnerabilities faster and with less friction. This has strengthened our overall security posture, improved collaboration with our development teams around remediation, and given leadership greater visibility into the risks we are actually facing.

API-Driven Findings and Easy Bounty Budget Tracking
Reviewed on Sep 23, 2026
Review provided by G2
What do you like best about the product?
As an engineer, I really appreciate the API availability. It lets me pull findings via the API and feed them into triage agents, which helps me develop fixes for those findings more efficiently. I also like that H1 helps me track my bounty budget and related expenses.
What do you dislike about the product?
There needs to be a more structured approach, with clear terms, for researchers who request higher payouts. Also, when researchers submit findings, HackerOne should flag possible duplicates. It doesn’t have to show the full details of those duplicates, but it should at least indicate that a similar report has already been submitted.
What problems is the product solving and how is that benefiting you?
H1 is helping us maintain a more continuous approach to testing and reviewing our systems, since vulnerabilities can be detected at any time. This is a big improvement over relying only on scheduled pentests, which can leave you blind until the next cycle.

It’s easy to use, and it offers numerous qualified researchers, along with new integrations and tools.
What do you dislike about the product?
The report staging system felt a bit complex to understand at first, and it took me some time to get familiar with how it works.
What problems is the product solving and how is that benefiting you?
Getting valuable security reports from well-qualified researchers, along with a third-person perspective on security.

Hai Makes Complex Reports Easy
Reviewed on Sep 10, 2026
Review provided by G2
What do you like best about the product?
I've grown to love Hai! It's very helpful when receiving complex reports.
What do you dislike about the product?
The platform can be buggy at times, especially when I’m navigating between our public program and our private program. I also find it difficult to locate certain areas in the UI because there are so many different sections, which can make things feel a bit hard to track down.
What problems is the product solving and how is that benefiting you?
It’s been helping us close gaps in our attack surface. Being able to share findings with teams—along with proof that an issue is actually exploitable—makes it much easier to prioritize and get the finding addressed ASAP.
