D3 Security vs Prophet Security (2026)
Both investigate at real depth and one publishes what that produces, at 10 and 8.5 of 14.
D3 comes from orchestration heritage and runs full second tier depth attack path discovery on every alert, generating bespoke playbooks at runtime and a structured case file in under two minutes, publishing that up to 95 percent of alerts are triaged and investigated in that window. Prophet runs continuously learning agents with explicit auditable reasoning per alert and single tenant VPC deployment, from triage through threat hunting. D3 publishes results; Prophet publishes its reasoning, and both are more evidence than most of this lane offers.
Choose D3 Security if
- Documented coverage is broader and a published triage percentage is the evidence you want.
- Attack path discovery at second tier depth is analysis you cannot do at volume today.
- Runtime generated playbooks beat maintaining a library of them.
Choose Prophet Security if
- Single tenant VPC deployment is a hard requirement.
- Auditable reasoning per alert is what your analysts will actually read and trust.
- Continuously learning agents adapting to your environment is the model you want.
