Featured Reviews

OndrejKOVAC - PeerSpot reviewer
Empower clients with risk-based vulnerability management through continuous workflow and valuable insights
Tenable Security Center could improve by implementing more dynamic data displays and translating reports into European languages. This is especially relevant in Central Eastern Europe, where clients often require reports in local languages. Additionally, the licensing model could be more flexible for managed security providers, similar to a pay-as-you-go model.
Sumit Bhanwala - PeerSpot reviewer
Cloud-based platform simplifies device and data center management
I find it to be good. The solution is cloud-based with the latest inspection engines, which I find to be amazing. We are less dependent on data centers and device management, which reduces our efforts significantly. It improves our device management, data center management, and updating devices. We need fewer engineers for this management, and it reduces time and efforts for data center management, device upgrades, and IT support.
