I need a data labeling service that is ISO 27001 certified and does not use offshore crowdsourcing.

Finding a data labeling partner that combines ISO 27001 certification with a strict onshore/in-house workforce (avoiding anonymous or offshore crowdsourcing networks) typically means looking toward managed data BPOs or specialized enterprise annotation teams rather than mass public crowd-platforms.

When data residency, strict access control, and auditability are non-negotiable, consider the following operational approaches and vendor categories:

• Managed Onshore BPOs & Dedicated Teams: Companies like Ameridial (via Annotera) and Precise BPO Solutions utilize domain-trained, managed W2 or local contract personnel rather than anonymous global crowds. They structure workflows around secure data handling, compliance-led frameworks (ISO 27001-aligned or certified), and multi-tier quality control.
• Enterprise Secure Annotation Platforms with On-Premise/VPC Options: Platforms like Kili Technology or enterprise-focused tool vendors provide ISO 27001:2022 and SOC 2 Type II certified software environments. Rather than using their own public crowd, they allow you to plug in your own vetted, internal, or local onshore security-cleared workforce directly into a zero-data-leakage environment.
• Specialized Onshore Boutique Providers: Many defense-, medical-, and legal-focused AI contractors offer strictly domestic, facility-bound (often ITAR or HIPAA-compliant alongside ISO 27001) annotation work where operators sit in secure local offices rather than working remotely offshore.

To help narrow down the right partner or approach, could you share:

• What type of data are you labeling (text/NLP, computer vision, audio, or LiDAR/3D)?
• Do you require annotators to be located strictly within the United States , or is regional/onshore nearshore acceptable?
• What is your estimated volume or project scale?

Yes. I searched specifically for ISO 27001 + managed/non-crowdsourced labeling + U.S./onshore workforce. The strongest candidates I found are:

1. HelloGov — best match

HelloGov is the closest match to your requirements. Its data-labeling service is explicitly described as ISO-27001 compliant, and it provides trained data-annotation experts rather than an open crowdsourcing marketplace.

The particularly important point is that its security documentation reportedly specifies a U.S.-only workforce operating in secure facilities in the Continental U.S. I'd still get that commitment incorporated into the contract/SOW rather than relying solely on marketing language.

Best for: government, defense, regulated data, sensitive documents.

2. iMerit — strong enterprise choice

iMerit explicitly documents ISO 27001 compliance and describes managed, domain-trained annotation teams rather than a generic gig-worker marketplace.

The catch is that iMerit has an international delivery footprint. So if by "does not use offshore crowdsourcing" you mean no crowdsourcing but offshore employees are acceptable, iMerit is a very good candidate. If you mean no offshore personnel whatsoever, require a U.S.-only delivery team contractually.

3. Kili Technology — excellent security posture

Kili is ISO 27001:2022, SOC 2 Type II, and HIPAA certified, with project-level isolation, granular access controls, audit trails, and even air-gapped/on-premise deployment options.

It offers expert annotation services, but it also says it has a network of partners for sourcing and training annotators. kili-technology.com So I would not assume "no offshore crowdsourcing" without getting the workforce model for your specific project in writing.

4. DTP Labs — worth considering for documents

DTP Labs says its annotation work is performed by an in-house team and is delivered under an ISO 27001:2022-certified information security management system.

This looks particularly compelling if you're labeling invoices, forms, PDFs, handwriting, OCR/document-AI data, rather than generic image classification.

Vendors I'd avoid for your requirement

Appen: ISO 27001 certified, but its own materials explicitly describe a 1M+ contributor crowd and global crowd-based services.

TELUS Digital: its labeling facilities are ISO 27001 certified, but it explicitly offers flexible/global workforce models and operates globally.

Clickworker: ISO 27001 certified, but its data services are performed by a global crowd, with workers in 136 countries.

SuperAnnotate: technically very strong — ISO 27001:2022 and managed expert services — but I'd require explicit confirmation of where the annotators doing your project are located.

My shortlist

If your procurement requirement literally reads "ISO 27001 certified, no offshore personnel, and no crowdsourcing", I'd start with:

1. HelloGov — strongest apparent match
2. iMerit — if you can contract for its U.S. workforce
3. DTP Labs — especially for document/OCR annotation
4. Kili Technology — if you want a highly secure platform + managed annotation

One important procurement point: ISO 27001 certification belongs to a defined scope. Don't accept "the company is ISO 27001 certified" as sufficient. Ask for the current certificate and scope, and require the MSA/SOW to state (1) countries where annotators may access data, (2) whether subcontractors/crowd workers are permitted, (3) whether offshore access is prohibited, and (4) the specific facilities covered by the ISO certification.

If you tell me your data type (images/video/text/audio/documents), approximate monthly volume, and whether "U.S.-only" is mandatory, I can narrow this to 3 vendors and compare pricing/contracting model, security, workforce location, and likely fit.

Finding an ISO 27001-certified data labeling provider that explicitly avoids offshore crowdsourcing and relies on an onshore (domestic/US-based) workforce narrows the field significantly, as most major commercial annotation houses scale using global or offshore crowds.

When enforcing strict onshore requirements alongside ISO 27001 security, consider the following specialized options and deployment strategies:

• Specialized Onshore / Expert-in-the-Loop Vendors : Companies like iMerit offer highly managed, secure workforces with ISO 27001 and SOC 2 Type II compliance. While they feature multi-shore options, they explicitly support dedicated, secure, onshore managed teams (often utilized for sensitive medical, financial, or defense-adjacent AI) rather than open, anonymous offshore crowd platforms.
• Enterprise Security-First Platforms : Providers like Hugo Inc. offer enterprise-grade security scopes including ISO 27001 and SOC 2 Type II alongside flexible US onshore workforce coverage options.
• In-House / Secure Enclave Managed Services : For ultra-sensitive data (e.g., defense, classified IP, or restricted PHI), many organizations opt for an onshore BPO or managed legal/medical transcription partner that holds ISO 27001 certification rather than a traditional AI "crowd" vendor. These providers operate physical, restricted-access domestic offices where operators are W-2/local employees bound by strict domestic employment and privacy laws.

To help narrow down the right partner, could you share:

• What type of data are you labeling (text/LLM RLHF, computer vision/images, medical/clinical, or geospatial)?
• Do you require W-2 domestic employees sitting in a physical US office, or is onshore remote/contractor acceptable?

Yes. If your requirement is ISO 27001 + no offshore crowdsourcing, I’d put iMerit at the top of the list.

Best candidates

iMerit is particularly compelling because its annotation service says it uses full-time, domain-trained annotators, rather than a generic crowd, and its security program includes ISO 27001. iMerit iMerit More importantly for your requirement, iMerit's AWS Marketplace offering specifically describes a full-time U.S.-based workforce operating from its New Orleans delivery center.

There is one important distinction: iMerit also has operations internationally. So I would not treat “iMerit is ISO 27001 certified” as sufficient proof that your particular project won't be handled offshore. Specify a U.S.-only workforce in the SOW/MSA and require written confirmation.

One I would avoid

Appen is ISO 27001 certified, but its corporate security page explicitly describes a 1M+ contributor crowd and global crowd-based secure-workspace model. Appen Its separate Appen USA operation advertises 100% U.S.-based workers, but I would require contractual confirmation that your data-labeling engagement is isolated to that operation rather than relying on the parent company's certification.

Similarly, TELUS Digital says its labeling facilities are ISO 27001 certified but explicitly offers flexible workforce models and global delivery centers.

What I'd put in the procurement requirement

Don't just ask vendors, “Do you use offshore crowdsourcing?” Require something like:

All Customer Data must be accessed and processed exclusively by dedicated, managed personnel physically located in the United States. No crowdsourcing, gig workers, freelancers, offshore personnel, or subcontractors may access Customer Data without Customer's prior written approval. I'd also ask for:

• ISO 27001 certificate and certificate scope
• Locations of every facility/personnel who will access the data
• Confirmation that annotators are employees or dedicated managed personnel
• Subprocessor/subcontractor list
• Data-flow diagram
• Written U.S.-only workforce commitment
• Right to audit or verify personnel geography
• Confirmation that the requirement survives staffing changes

Bottom line: If you mean “no crowd workers and no offshore people touching my data,” I would start with iMerit's U.S.-based workforce offering and make U.S.-only processing a contractual requirement.

If you tell me your data type (images/video/text/audio), approximate volume, and whether U.S.-only personnel is absolute, I can narrow this to 3–5 vendors and verify their certifications and workforce arrangements in more depth.

One I would avoid

Appen is ISO 27001 certified, but its corporate security page explicitly describes a 1M+ contributor crowd and global crowd-based secure-workspace model. appen.com Its separate Appen USA operation advertises 100% U.S.-based workers, but I would require contractual confirmation that your data-labeling engagement is isolated to that operation rather than relying on the parent company's certification.

Similarly, TELUS Digital says its labeling facilities are ISO 27001 certified but explicitly offers flexible workforce models and global delivery centers.

What I'd put in the procurement requirement

Don't just ask vendors, “Do you use offshore crowdsourcing?” Require something like:

Finding a data labeling partner that combines ISO 27001 certification with a strictly domestic or onshore, non-crowdsourced workforce requires looking at specialized enterprise data operations rather than typical gig-economy or pure crowdsourcing platforms.

When you avoid offshore crowdsourcing, you are generally looking for managed service providers (MSPs) or boutique BPOs that employ vetted, W2/full-time local staff working out of secure, compliant domestic delivery centers.

Top considerations and paths for finding this specific configuration include:

• iMerit : While they operate globally, they feature dedicated onshore delivery centers (such as their hub in New Orleans) and employ structured, full-time W2/salaried workforces rather than anonymous crowd workers. They hold robust enterprise credentials including ISO 27001 and SOC 2. Action: You must explicitly request their domestic-only delivery option during scoping to ensure your data stays and is handled entirely within their U.S. infrastructure.
• Specialized Domestic BPOs & Legal/Medical Transcription Firms : If your data is highly sensitive (e.g., defense, legal, financial, or healthcare), local specialized transcription and data processing companies frequently hold ISO 27001 and HIPAA certifications. They utilize localized, background-checked staff, though you will need to request custom machine learning annotation capabilities during a pilot.
• AWS SageMaker Ground Truth Plus (with strict perimeter configurations) : For organizations needing to keep data strictly inside a secure ecosystem without external crowds, AWS-managed labeling services operate under AWS's robust ISO 27001 and SOC compliance framework. However, you must verify their workforce configuration for your specific tier to guarantee it meets your onshore requirements.

To help narrow down the best path, could you share:

• What data modality are you labeling (computer vision, 3D point clouds, NLP text, or RLHF/LLM data)?
• Do you require workers to be U.S. citizens/based strictly inside the United States , or is an onshore delivery model in a specific allied region acceptable?

Yes. I found a few vendors that fit, but the cleanest match for “ISO 27001 + no offshore crowdsourcing” is HelloGov, particularly if U.S.-only handling is important.

1. HelloGov — strongest fit

HelloGov specifically markets data labeling to the federal government. Its labeling service says it is compliant with ISO-27001, and its broader security documentation says all personnel are U.S. citizens, with operations only in secure facilities in the Continental U.S.

It also describes its workforce as trained annotation specialists rather than an open crowd, and offers both managed labeling and its Carnegie Studio platform.

If your requirement is literally “data never goes offshore and labeling isn't performed by a crowdsourced marketplace,” this is the first vendor I'd contact.

2. iMerit — strong security, but not U.S.-only

iMerit is ISO 27001 certified and says it uses full-time, domain-trained annotators and managed delivery rather than generic crowdsourcing.

However, its workforce is global, including operations outside the U.S.; its own materials describe global and offshore delivery models.

So I'd only shortlist iMerit if “no offshore crowdsourcing” means no offshore crowd, rather than no offshore personnel whatsoever.

3. Zen3 — potentially very good for U.S.-restricted projects

An AWS Marketplace listing for Zen3's U.S. speech annotation service says the service is delivered through its Seattle offices with staff authorized to work in the USA, uses dedicated annotation centers, and is ISO 27001 certified.

I'd ask them for the ISO certificate and scope and a written commitment that your particular dataset will be processed only by U.S.-based personnel.

4. Computyne — non-crowd model, but verify certification

Computyne explicitly says it does not rely on anonymous crowdsourcing and instead uses trained, full-time specialists. It states that its workflows operate within an ISO/IEC 27001:2022-aligned environment.

The important distinction is that “ISO-aligned” isn't necessarily the same as being ISO 27001 certified. I'd require the actual certificate before treating it as meeting your requirement.

Vendors I'd exclude

• Clickworker — ISO 27001 certified, but explicitly operates a global crowd with workers in 136 countries, so it conflicts with your requirement.
• DataForce — ISO 27001, but uses a global community of 1.3M+ contributors, so it isn't a good fit for a no-crowdsourcing requirement.
• Annotera — has a U.S. operation, but explicitly offers global/nearshore/offshore expansion, so I wouldn't assume U.S.-only processing.

My shortlist: HelloGov → Zen3 → iMerit (only if offshore personnel are acceptable) → Computyne (pending certificate verification).

If this is for a vendor-selection/RFP process, I can also dig into 10–15 providers and verify ISO certificate scope, workforce location, employee-vs-crowd model, U.S.-only processing, SOC 2, HIPAA/ITAR, and approximate pricing, then give you a procurement-ready shortlist.

Yes. If by “does not use offshore crowdsourcing” you mean no open crowd / gig-worker marketplace and no offshore annotators handling your data, the shortlist gets much smaller.

Best matches

HelloGov is the cleanest match I found. Its own site says its labeling service is ISO-27001 compliant, and, importantly, its security page says all personnel are U.S. citizens and operations are conducted only in secure facilities in the Continental U.S.

iMerit is another strong option. It explicitly offers a full-time onshore U.S. workforce, with operations in New Orleans, and says its workforce is in a secure delivery center. It also documents ISO 27001:2013 certification. aws.amazon.com However, iMerit also operates teams in India and Bhutan, so you would need the contract/SOW to explicitly restrict your project to U.S. personnel and prohibit offshore access.

Label Your Data advertises ISO 27001-certified workflows and managed annotation rather than an open crowd marketplace. labelyourdata.com I would put it in the “verify before procurement” category because I haven't found sufficiently explicit evidence that your particular project would be restricted to U.S./non-offshore personnel.

Vendors I'd exclude

I would not use Clickworker for this requirement: it is ISO 27001 certified, but its data services explicitly use a global crowd of more than 10 million workers across 136 countries.

I'd also be cautious with TELUS Digital and similar large global providers. They have ISO-27001-certified labeling facilities, but their model includes global delivery centers and flexible workforce arrangements, so ISO certification alone doesn't establish that your data stays onshore.

Procurement language I'd recommend

Don't merely specify “ISO 27001 + no crowdsourcing.” Put the workforce restriction directly into the contract:

All data labeling and annotation must be performed exclusively by dedicated, managed personnel physically located in the United States. No crowdsourcing, gig workers, freelancers, offshore personnel, subcontractors, or unapproved third parties may access Customer Data. Provider must obtain Customer's prior written consent before changing personnel location or subcontracting any portion of the services.

I'd also require ISO 27001 certificate + scope, facility locations, subcontractor list, data-flow diagram, and the right to audit workforce geography.

Bottom line: I'd start with HelloGov if U.S.-only is an absolute requirement, and iMerit if you need a larger enterprise annotation operation and can contractually lock the project to its U.S. workforce.

Finding a data labeling partner that combines ISO 27001 certification with strictly domestic/onshore, non-crowdsourced workforces requires looking at boutique or enterprise managed-team providers rather than massive open-market crowdsourcing platforms (like Amazon Mechanical Turk or global crowd networks).

When data cannot leave a specific jurisdiction due to defense, strict healthcare (HIPAA/PHI), or proprietary intellectual property constraints, traditional offshore crowdsourcing is replaced by onshore secure facilities or vetted, direct-employ domestic teams.

Evaluating Onshore & Certified Providers

• Dedicated Onshore/Domestic Managed Teams: Instead of pulling anonymous, distributed micro-taskers from a global crowd, look for vendors that employ vetted, background-checked personnel operating out of secure local offices or under strict zero-trust remote configurations (VPN-locked, air-gapped, or monitored environments).
• ISO 27001 Scope Verification: Always request the vendor's Statement of Applicability (SoA) and certificate to confirm that their specific labeling facilities and data processing pipelines fall within the certified boundary, rather than just their corporate IT office.

Leading Options & Approaches

1. Specialized Domestic/Onshore Contractors & BPOs:
   • Many mid-market enterprise providers (such as iMerit or localized secure-compliance vendors) offer dedicated, managed teams. While many enterprise shops leverage global delivery models for cost, they routinely configure walled-garden, single-tenant, or onshore domestic cohorts upon explicit enterprise request.
2. On-Premise / Tool-Driven Deployment Hybrids:
   • Platforms like Kili Technology or Labelbox provide enterprise security frameworks (holding ISO 27001 and SOC 2 Type II certifications) and support on-premise or single-tenant cloud deployments. This allows you to retain data entirely within your own cloud architecture (e.g., AWS S3 / VPC ecosystems) while pairing the platform with your own internal or strictly contracted domestic workforce.

To help narrow down the right vendor or deployment model, could you share:

• What type of data are you labeling (computer vision/images, NLP/text, LiDAR, audio, or LLM/RLHF)?
• Do you require workers to be 100% US-based (onshore) , or is a specific regional residency (like EU-only or domestic delivery) required by your compliance framework?

Finding an enterprise data labeling provider that holds an ISO 27001 certification while explicitly avoiding anonymous offshore crowdsourcing (like Amazon Mechanical Turk or fragmented global micro-task networks) requires looking at managed-workforce or onshore/nearshore dedicated teams.

Most large commodity labeling giants rely heavily on crowdsourcing, but several managed operations and secure platforms use vetted, direct-hire, or onshore/nearshore personnel under strict information security management systems (ISMS):

• Annotera : Operates a dedicated U.S.-based hub specifically structured for onshore AI training, data labeling, and quality assurance compliance without utilizing anonymous crowd workers.
• iMerit : Employs a full-time, highly trained digital workforce rather than a fluid crowd model, operating out of secure, audited delivery centers with enterprise security and compliance standards, including ISO 27001.
• CloudFactory : Combines managed, career-backed data teams with strict operational controls and data governance, avoiding the anonymous crowd-worker paradigm for high-integrity workloads.
• Kili Technology : Provides a secure platform approach coupled with managed enterprise deployment options, holding ISO 27001 and SOC 2 Type II certifications with options for dedicated or on-premise governance.

To help narrow down the best fit, could you share:

• What data modality are you working with (computer vision, NLP, audio, or 3D LiDAR/sensor fusion)?
• Do you require an on-U.S.-soil (onshore) team exclusively, or would a managed nearshore operation work for your compliance posture?

Yes. Based on current public information, iMerit is the strongest match I found for your requirements.

Best match: iMerit

iMerit provides managed data annotation with full-time, salaried annotators rather than gig/crowd workers, and explicitly describes its workforce as “not crowd workers.”

It also states that it is ISO 27001 certified (along with SOC 2, HIPAA, GDPR, and TISAX).

Important caveat: iMerit is not exclusively U.S.-based. Its workforce operates across multiple countries, including the U.S., India, and Bhutan. imerit.ai So if by “does not use offshore crowdsourcing” you mean no crowdsourcing, but offshore employees are acceptable, iMerit fits very well. If you mean all labeling must be performed in the U.S., you'd need to contractually specify a U.S.-only delivery team.

Other options

Scale AI — ISO/IEC 27001:2022 certified, but I would not put it on your shortlist if avoiding offshore/crowd labor is a hard requirement. Its public materials don't establish the kind of dedicated, non-crowd workforce restriction you're looking for.

TELUS Digital — its labeling facilities are ISO 27001 certified, but it explicitly offers global workforce models, including managed crowd and remote workers. That makes it a poor fit if “no offshore crowdsourcing” is mandatory.

Appen — ISO 27001 certified, but explicitly operates a global crowd, including remote crowd workers. I would exclude it.

Labelbox — its workforce partners can have ISO 27001 compliance, but its managed workforce is powered by the Alignerr community and BPO partners, so it doesn't cleanly meet your no-crowdsourcing criterion.

My recommendation

If your requirement is:

ISO 27001 + professional employed annotators + no gig/crowd marketplace

I'd start with iMerit.

If your actual requirement is stricter:

ISO 27001 + 100% U.S.-based human annotators + no offshore personnel whatsoever

then I would not yet consider iMerit a confirmed match without a contractual commitment specifying U.S.-only personnel and data handling.

If you tell me whether “U.S.-only” is mandatory, I can narrow this down to vendors that satisfy all three requirements and verify their certifications and workforce model.
