Common Mistakes to Avoid
Misalignment between assessment scope, internal ownership, and engineering follow-through creates predictable delays across many enterprise engagements.
Choosing a provider that cannot translate findings into prioritized remediation actions
Rapid7 Advisory Services and Deloitte focus on remediation-first reporting and prioritized network remediation actions that help teams act on network exposure and lateral movement routes. Providers with less implementation-oriented output increase the risk of artifacts that require extra internal mapping before tickets can be created.
Running an assessment without securing the stakeholder and access coordination required for validation
Mandiant Consulting and Trustwave can require heavy stakeholder time from networking and security teams because detection coverage validation and evidence-based reporting depend on access to network and logging baselines. PwC, Deloitte, and KPMG similarly depend on timely network diagrams and configuration evidence to keep validation credible.
Assuming network-only assessment work will replace application and endpoint coverage
Trustwave explicitly scopes network assessment coverage and notes that network-only testing may not fully replace application or endpoint testing. Kroll and KPMG both align network-focused assessment deliverables to risk and controls, but full enterprise risk programs typically need separate workstreams for application and data-layer security testing.
Underestimating how documentation volume and formatting can slow engineering adoption
Rapid7 Advisory Services and PwC can produce documentation-heavy outputs that take effort for teams wanting immediate fixes. Booz Allen Hamilton and Trustwave deliver structured findings, but internal mapping into ticketing workflows still determines how quickly remediation execution starts.
