  • Buying exploit reports without a remediation plan that maps to engineering work items

    Quantstamp maps findings to specific contract paths and remediation steps that engineers can action, while generic report outputs often leave execution gaps.

  • Expecting continuous transaction monitoring automation from governance-first consultancies

    KPMG emphasizes governance evidence and investigation support, and it places less emphasis on API-first automation for continuous transaction monitoring, so buyers should plan automation integration separately if needed.

  • Underestimating internal ownership requirements for evidence packages and governance approvals

    PwC and EY tie investigations and control evidence to operational artifacts and governance integration, which still depends on named internal owners for evidence production and approvals.

  • Choosing an architecture roadmap advisory without implementation ownership alignment

    Galaxy Digital provides advisory-to-execution roadmapping for architecture selection sequencing, so the organization must already define implementation ownership to land the plan cleanly.
