If you're worried that your training set has been deliberately “poisoned,” I'd look for a specialist in AI data integrity auditing and adversarial machine-learning security, rather than a conventional data-quality auditor.
A proper assessment should investigate whether malicious or manipulated samples, hidden backdoors, corrupted labels, or compromised data sources could influence your model's behavior. NIST's adversarial machine-learning guidance identifies data poisoning as a threat across pretraining, fine-tuning, and other stages of the model lifecycle.
These providers publicly describe services relevant to dataset integrity, data poisoning, or adversarial AI testing. They're a shortlist to investigate, not an independent certification of their capabilities.
1. Anomaly Labs
(Dataset-focused)
Describes a “data quality red team” service that adversarially examines corpora, investigates provenance, flags suspicious sources, and returns corrected data with a report and comparison against the original. A strong candidate if you want an audit of the dataset itself.
Visit Anomaly Labs anomalylabs.co
2. Mjolnir Security
Best match for a technical security assessment. Its stated scope includes training-data provenance, statistical anomaly detection, backdoor detection, label-flipping attacks, and clean-label poisoning simulations. It also describes technical findings and remediation recommendations.

3. Breach Arc
Focuses on security across AI models, training pipelines, data storage, and dependencies. Its published AI/ML security scope explicitly includes data poisoning and supply-chain attacks, making it worth considering when the concern extends beyond individual records to how your dataset is assembled.

4. Integrum.one
Offers a platform-oriented approach to data integrity: provenance and lineage, detection of poisoned or mislabeled records, quarantine, model safety testing, and audit reports. Its website currently indicates limited early access, so confirm availability before planning a project.

5. iBovi
Offers human-led AI red teaming covering data poisoning, backdoor triggers, label manipulation, and compromised data supply chains. Particularly relevant if you want specialists to simulate an attacker rather than simply run a data-quality scan.

Not every AI security firm actually inspects a training corpus. Before hiring anyone, ask for a written scope covering these five areas:
| Audit area | What they should demonstrate |
|---|---|
| Data provenance | Where records originated, who supplied them, and whether sources were altered or compromised |
| Poison detection | Identification of suspicious examples, coordinated injections, and anomalous clusters |
| Backdoor testing | Simulations of trigger-based behaviors, including clean-label poisoning where relevant |
| Model-level validation | Controlled experiments to determine whether suspect samples change model behavior |
| Remediation and evidence | Reproducible findings, affected-record identifiers, quarantine or cleanup recommendations, and a retest |
One important distinction: a clean-looking dataset is not proof that it is unpoisoned. Some attacks use correctly labeled, superficially normal examples, so an audit should combine data analysis with adversarial experiments and, where possible, comparisons of models trained on clean and suspect subsets.
Start with Anomaly Labs if your primary objective is to inspect and clean a large existing corpus, and Mjolnir Security if you want a more traditional adversarial security assessment with attack simulations and technical evidence. Verify their relevant experience, independent references, and ability to work with your dataset scale before selecting either.
One question would help narrow this down: What kind of training data are you worried about?
1. Dataset type
Web-scale text / LLM pretraining
Fine-tuning, instruction or preference data
Images, audio or video
Structured or labeled ML data
RAG corpus or knowledge base
2. What do you need?
Audit an existing dataset
Test whether a trained model was poisoned
Continuously screen incoming data
Independent third-party assurance
3. Approximate scale
Small (under 1M records)
Medium (1M–100M records)
Very large (100M+ records or billions of tokens)

Worrying about data poisoning is entirely valid—once a compromised dataset is baked into a model's weights, cleanup becomes extraordinarily difficult.[](https://www.crowdstrike.com/en-us/cybersecurity-101/cyberattacks/data-poisoning/)
Dataset auditing and AI supply chain security are handled by specialized AI security firms, ML observability platforms, and enterprise AI red-teaming providers. Rather than traditional auditors, these companies use automated sanitization, data provenance tracking, and adversarial stress-testing.[](https://neuraltrust.ai/blog/best-ai-red-teaming-platforms)[[2](https://neuraltrust.ai/blog/best-ai-red-teaming-platforms)](https://snyk.io/articles/what-is-a-data-poisoning-attack/)[[3](https://snyk.io/articles/what-is-a-data-poisoning-attack)]()

Yes, auditing training datasets for adversarial vulnerabilities , backdoors, and label corruption is an emerging and critical discipline within AI Security and Trust, Risk, and Security Management (TRiSM).[](https://www.crowdstrike.com/en-us/cybersecurity-101/cyberattacks/data-poisoning/)[[2](https://www.llm-sec.dev/labs/data-poisoning)](https://www.llm-sec.dev/labs/data-poisoning)[[3](https://www.ampcuscyber.com/knowledge-hub/what-is-ai-data-poisoning)](https://www.ampcuscyber.com/knowledge-hub/what-is-ai-data-poisoning/)
While automated scanning for training data poisoning is less "out-of-the-box" than traditional software vulnerability scanning (due to the scale and complexity of machine learning data), several specialized platforms, security services, and methodologies exist to address this risk.
Several AI-native security posture management (AI-SPM) and red-teaming platforms evaluate the security of the AI supply chain, including data pipelines, vector databases (RAG poisoning), and model artifacts:

Are there platforms that offer dataset auditing to ensure our training data hasn't been compromised by adversarial attacks?
To help me point you toward the most relevant tools or services, could you share:
If you need an external, deep-dive audit of a proprietary dataset rather than a software tool, you typically turn to specialized boutique AI security firms or major consultancies with dedicated adversarial AI practices:
If your team prefers an in-house audit using established academic and industry-standard algorithms, look into these methodologies:
To help narrow down the best path forward, tell me:
I can recommend whether you need an automated scanning tool , an external security auditor , or an open-source algorithmic approach.
Yes. There is now a small but credible ecosystem of AI/ML security firms and tools that can audit training-data integrity and poisoning risk. The important distinction is that some primarily assess the pipeline and controls, while others actually test datasets/models for evidence of adversarial manipulation.
| Provider | What they can assess | Fit for training-data poisoning |
|---|---|---|
| HiddenLayer | AI risk assessments, data/model supply-chain security, adversarial testing, model lineage | Strong — explicitly covers data-pipeline and supply-chain risks and poisoning as an adversarial-ML threat. |
| Mjolnir Security | Dataset provenance, statistical anomalies, backdoor detection, label-flipping and clean-label attack simulation | Very direct match — its assessment explicitly advertises data-poisoning analysis and trained-model backdoor detection. |
| OPSWAT | Data-pipeline inspection/sanitization, malicious content, poisoned data, AI/cloud-storage threats | Good for pipeline-level protection and ongoing ingestion rather than a one-time forensic audit. |
| Breach Arc | ML pipeline, training-data storage, adversarial testing, poisoning, supply-chain attacks | Good for an offensive-security assessment of the whole ML stack. |
There are also research/open-source approaches, but they're more useful as components of an audit than substitutes for an independent assessment. For example, the academic literature covers dataset poisoning and backdoor attacks extensively, including detection/defense techniques.
If your concern is “Could our existing training corpus already have been poisoned?”, I would not commission a generic “AI security assessment.” I'd request a training-data integrity/poisoning assessment with these workstreams:
Provenance reconstruction
Tamper/integrity analysis
Statistical/anomaly analysis
Targeted poisoning/backdoor investigation
This matters because a clean-looking dataset isn't necessarily a clean dataset: web-scale datasets can be vulnerable to things such as split-view poisoning, where the content behind a previously collected URL changes later. The FBI's AI-data-security guidance specifically recommends cryptographic hashes, download-time verification, periodic rechecking and provenance/certification controls for this problem.
The OWASP AI Security Verification Standard (AISVS) has a dedicated Training Data Integrity & Traceability section covering data origin, inventory, storage/transfer integrity and monitoring for unauthorized modification or poisoning. That gives you a useful checklist for evaluating whether a vendor's proposed audit is actually comprehensive.
OWASP AISVS — Training Data Integrity & Traceability
One caution: many vendors market “AI security” broadly, but that doesn't mean they can establish whether your historical corpus was actually poisoned. I'd require a statement of work that distinguishes preventive controls, current-dataset anomaly detection, and forensic evidence of past poisoning.
If you tell me roughly what kind of training data you have (e.g. web-scale text, code, images, instruction-tuning data, proprietary documents), I can narrow this to the most appropriate audit firms and specific tests to request, including approximate engagement scope.
