Acunetix should have better integration with newer tools such as GitHub and Azure DevOps.

It has a very simple user interface, and it gives you a quick response—if you submit a bug, someone reaches out to you within minutes, telling you they will verify the bug, and it can be verified in just a few days, sometimes even less than a day, which stands out for me.
Senior ICT Security Consultant at Applied Principles Limited
HackerOne is a very good platform with the trust of different companies including Shopify, PayPal, and Uber.
Senior Software Developer at hireHQ
I find bug bounty programs most valuable for our organization because they invite researchers from around the globe to find bugs in our environment, allowing us to fix various severity vulnerabilities or bugs that, if left unaddressed, could lead to losing customers.

Unified risk scoring has improved our cloud visibility and simplifies remediation priorities
Qualys TotalCloud provides unified vulnerability and threat assessment across both IAS and SaaS. This solution provides a single prioritized view of risk, which helps reduce the work I would have to do. We are no longer based on CVSS; we are based on Qualys risk scoring, which is based on CVSS plus internal findings made by Qualys, and then assigns its own score. The TruRisk insight feature has found a small number of assets with high vulnerability scores, though I am cautious since some information is classified. Qualys TotalCloud has positively impacted our bank's performance, and we have definitely seen benefits after implementing this solution.

Identifies vulnerabilities across bulk web applications but needs better support and cleaner reports
The best feature Acunetix offers is the centralized dashboard and the quality of reports it generates, which includes various options for selecting reports and developer options for directly sharing the reports with developers. The centralized dashboard of Acunetix gives visibility into the security aspects of mass applications; for instance, with more than 200 applications, it provides a valuable overview of findings and necessary fixes, along with a high-level summary that helps us achieve compliance through monthly and sometimes weekly scanning. In terms of reporting, Acunetix is excellent because it can generate different types of reports, such as an executive summary report, detailed reports, and developer reports that can be shared directly with developers. Acunetix positively impacts my organization by helping identify outdated libraries and applications, including legacy applications vulnerable to old attacks based on OWASP Top 10, thus aiding in compliance checks for PCI DSS and OWASP. Acunetix provides a centralized report with compliance-related aspects and a vulnerability timeline, effectively helping reduce vulnerabilities and save time.

Crowdsourced security has strengthened our bug discovery and improved vulnerability response
HackerOne is already doing well, although I believe implementing stricter SLAs for the time to first response and time to bounty would help prevent researchers' burnout, especially regarding duplicate submissions. I suggest systematic bug rewards because currently, if a researcher finds one bug in multiple places, they often only get paid for one. Improving the handling of systemic vulnerabilities would encourage deeper research. Additionally, improving multi-currency and crypto payout options would help make the platform more accessible globally.
