Israel Cavazos Landini - PeerSpot reviewer
Weekly insights and risk analysis facilitate informed security decisions
I appreciate the weekly insights Zafran provides, which include critical topics for networks and IT security, allowing us to evaluate which insights apply to our environment. The organization score feature is valuable to keep the leadership team updated on how our infrastructure fares security-wise. The applicable risk level versus base risk level feature is beneficial because prior to Zafran, we only used the base risk level, but now understand that risk depends on the asset itself. Zafran is an excellent tool.

Faizan Nehal - PeerSpot reviewer
Platform supports skill development with effective vulnerability reporting
Everything has become slower on HackerOne. I have noticed that older researchers receive all the private invites while newer ones receive fewer. The same goes for real-life events, where the same people are invited repeatedly. There are no clear guidelines for being invited to programs and conferences, and the process for receiving invitations appears arbitrary.
