Comparison Table
Deloitte
enterprise_vendorDeloitte delivers generative AI security assessments, red teaming, governance, and control testing.
Consultant-led red team plans that convert threat models into evaluation rubrics and re-runnable attack case suites for mitigation verification.
Deloitte’s differentiator in AI red teaming is the combination of structured test design and hands-on execution by consultants who can map failures to specific attack paths and then verify mitigations with controlled re-runs. Deloitte’s typical workflow fits organizations that already run security assessments across SDLC stages and want AI safety testing integrated into those same decision gates. The service is most credible when test scope includes real prompts, system prompts, tool interfaces, and observed model or agent behaviors rather than only synthetic prompt lists.
A key tradeoff is that outcomes depend on access to deployment context such as API calls, tool schemas, and logging needed to reproduce attacks and measure attack success rate. Deloitte fits best when there is an identified owner for remediation and when engineering can support iterative test cycles across prompt changes, guardrail updates, and tool permission tuning.
- +Engagement teams produce attack narratives mapped to concrete mitigations
- +Test scoping covers agent workflows and tool-use execution paths
- +Iteration supports re-running the same attack case after changes
- +Governance documentation links findings to evaluation rubrics
- –Reproducibility depends on deep customer access to prompts and logs
- –Requires scheduling and coordination across security, risk, and engineering stakeholders

How to Choose the Right ai red teaming
AI red teaming in this guide covers how teams run adversarial testing against generative AI systems, then package the results into mitigation validation artifacts that engineering and governance stakeholders can reuse. Deloitte leads this set with consultant-led plans that convert threat models into evaluation rubrics and re-runnable attack case suites. Accenture, Coalfire, and Dragonfly Security are also covered with delivery models that tie adversarial findings to remediation follow-through or evidence capture.
The narrative sections after the individual provider cards focus on integration depth, automation and API surface, and governance controls where those capabilities show up in delivery. Deloitte emphasizes re-runnable case suites and mitigation verification workflows that depend on prompt and log access. Accenture and Coalfire prioritize engineering remediation mapping or scenario-driven evidence packaging, while IBM Consulting and Google Cloud Mandiant connect test attempts to identity, orchestration, or detection evidence.
AI red teaming services that produce mitigation-validated attack case suites
AI red teaming is adversarial testing against LLM and agent workflows using repeatable attack cases that target real application flows, including instruction hierarchy breaks and tool-use execution paths. Deloitte’s delivery turns threat models into evaluation rubrics and re-runnable attack case suites so mitigation changes can be re-validated against the same failure modes.
Services in this guide also differ in how they connect attack evidence to governance and remediation owners. IBM Consulting links system-context testing to governance-linked mitigation owners through structured evidence workflows. Google Cloud Mandiant ties adversarial behavior attempts to Google Cloud detection and response evidence so findings map to the controls teams already monitor.
AI red teaming capabilities to map attacks to mitigation validation
AI red teaming services should produce re-runnable attack case suites so mitigation changes can be measured against the same failure modes. Deloitte is built around consultant-led plans that convert threat models into evaluation rubrics and re-runnable attack case suites for mitigation verification.
Beyond attack execution, the value comes from how evidence gets structured for owners who will change systems. Coalfire and PwC package evidence with remediation and governance artifacts that support mitigation validation workflows in client environments.
Re-runnable attack case suites and evidence packaging
Deloitte converts threat models into evaluation rubrics and re-runnable attack case suites so mitigation changes can be re-validated against the same failure modes. NetSPI delivers threat-scenario to red-team test case mapping through its established assessment workflow to support retesting with consistent evidence handling.
Agent workflow and tool-use execution coverage
Holistic AI targets test case packages that incorporate tool-use and instruction hierarchy failure paths into repeatable executions. Deloitte also scopes agent workflows and tool-use execution paths, but it ties that execution work to mitigation verification rubrics.
Governance-linked ownership of mitigations
IBM Consulting connects red-team observations to governance-linked mitigation owners through structured evidence workflows across identity and downstream systems. PwC runs governance-first engagement artifacts that connect AI red-team findings to control remediation workflows.
Cloud-native detection and response evidence mapping
Google Cloud Mandiant builds Mandiant-led assessment artifacts that connect adversarial attempts to Google Cloud detection and response evidence. This differs from Deloitte and Coalfire where the primary packaging goal is mitigation validation tied to client workflow constraints rather than detection evidence alignment.
Retesting loops that check mitigation effect and refusal safety
Humane Intelligence emphasizes retesting cycles that measure whether mitigation changes reduce observed adversarial success without degrading intended refusals. EY adds threat-model-to-attack-tree planning so red-team evidence maps into mitigation validation artifacts across end-to-end workflow misuse.
Choose an AI red teaming delivery model aligned to integration depth and repeatability
The first decision is whether the work is expected to stay repeatable through run-to-run comparisons or to stay one-off discovery focused. Deloitte and NetSPI are positioned around re-runnable test case mapping and evidence suited for retesting, while Accenture and Coalfire lean toward managed delivery that still outputs engineering-ready remediation artifacts but may slow rapid iteration.
The second decision is which stakeholders must consume outputs. IBM Consulting and PwC connect evidence to governance and remediation workflows through structured engagement artifacts, while Google Cloud Mandiant centers detection and response alignment with Google Cloud controls.
Pick a repeatability philosophy based on retesting requirements
If retesting against the same failure modes must happen after mitigation changes, Deloitte and NetSPI provide test case mapping intended for mitigation validation and retesting cycles. If mitigation validation can tolerate less self-serve repeatability and depends on engagement execution, Accenture and Coalfire fit managed red-team engagements that translate findings into engineering remediation or mitigation validation steps.
Match evidence packaging to who owns fixes
If governance teams and production owners must receive structured evidence tied to mitigation ownership, IBM Consulting and PwC connect observations or findings to governance-linked remediation workflows. If security engineering needs evidence that ties adversarial behavior to detection and response controls, Google Cloud Mandiant aligns test attempts with Google Cloud logs and security controls.
Verify agent and tool-use coverage for the system shape in production
If the target system includes tool use or agent execution paths, Holistic AI packages attack execution that incorporates tool-use and instruction hierarchy failure paths into repeatable test case packages. If the target system still needs re-runnable rubrics tied to mitigation verification, Deloitte pairs agent workflow scoping with evaluation rubric conversion.
Check turnaround constraints against governance-heavy delivery
If fast iteration is required, avoid assuming self-serve automation from governance-heavy delivery and coordinate timelines explicitly for services like Coalfire and PwC. If the organization can schedule cross-stakeholder testing and provide prompt and log access needed for reproducibility, Deloitte’s consultant-led plan supports re-runnable case suites.
Use retesting to prevent mitigation regressions in refusal behavior
If refusals and policy behavior must remain intact while adversarial success drops, Humane Intelligence runs retesting cycles that measure reduction in adversarial success without degrading intended refusals. If the priority is mapping end-to-end workflow misuse into structured evidence narratives, EY builds threat-model-to-attack-tree plans linking attack evidence to mitigation validation artifacts.
Who should buy AI red teaming services
AI red teaming services fit teams that have deployed or planned LLM and agent workflows and need adversarial testing tied to mitigation validation. This guide’s strongest alignment is for organizations that must prove fixes reduced attack success while preserving intended refusals and policy behavior.
Different providers match different operational realities. Deloitte and NetSPI emphasize re-runnable case suites and evidence for retesting, while IBM Consulting and PwC focus on governance-linked mitigation workflows and Google Cloud Mandiant focuses on detection and response evidence alignment.
Enterprise security and risk teams running governed AI programs

Organizations needing attack-to-mitigation evidence suitable for repeat validation cycles
Deloitte and NetSPI structure threat-scenario and rubric-driven attack cases so mitigation changes can be re-validated with retesting evidence packages.
Common mistakes in AI red teaming buying and delivery
A frequent failure mode is accepting attack screenshots without a re-runnable test case structure that enables mitigation validation. Deloitte and NetSPI are designed around re-runnable test case suites or test case mapping for retesting, while other models can still deliver findings that are harder to rerun.
Another frequent mistake is underestimating the access and coordination needed to reproduce failures and to route evidence to the right owners. Deloitte flags that reproducibility depends on deep customer access to prompts and logs, and IBM Consulting requires governance and stakeholder availability to keep test execution moving.
Buying red teaming for one-off vulnerability discovery but not for mitigation validation
Deloitte packages consultant-led attack plans into evaluation rubrics and re-runnable attack case suites for mitigation verification. NetSPI maps threat scenarios to red-team test cases built for retesting so mitigation effect can be measured.
Assuming self-serve automation when delivery depends on stakeholder coordination and client access
Coalfire and PwC describe governance-heavy delivery that increases coordination overhead for faster cycles. Deloitte’s reproducibility depends on deep customer access to prompts and logs, so scheduling and access provisioning must be planned.
Treating agent and tool-use risks as if they were only prompt risks
Holistic AI packages attack execution that includes tool-use and instruction hierarchy failure paths for repeatable test cases. Deloitte also scopes agent workflows and tool-use execution paths and maps those failures to mitigation verification rubrics.
Routing findings to security only when governance-linked mitigation ownership is required
IBM Consulting connects observations to governance-linked mitigation owners through structured evidence workflows. PwC connects AI red-team findings to control remediation workflows aligned with regulated enterprise programs.
Checking mitigation success without measuring refusal or policy regressions
Humane Intelligence runs retesting cycles that measure adversarial success reduction without degrading intended refusals. EY pairs threat-model-to-attack-tree planning with end-to-end workflow misuse evidence so mitigation validation covers more than single prompt behavior.
