I am looking for a secure file transfer solution that complies with ITAR regulations.

Yes. For ITAR-controlled technical data, I would avoid treating “secure file transfer” and “ITAR compliant” as interchangeable. There is no formal ITAR certification; compliance depends on how the solution is configured and operated, including who can access the data, where it resides, and how transfers are controlled. AWS explicitly notes this distinction.

Strong options to evaluate

• Virtru — Particularly attractive if you need controlled sharing with outside suppliers or partners. Virtru says its platform supports ITAR workflows with U.S. hosting, granular access controls, end-to-end encryption, and customer-controlled key management; its platform is also FedRAMP Moderate authorized.
• FileCloud — A good choice if you want a broader file-sharing/content-management platform rather than just transfer. FileCloud offers a FedRAMP High environment, detailed auditing, DLP, DRM, and policy-driven governance, and specifically positions it for CUI and ITAR data.
• Sharetru — Worth considering if your primary requirement is secure file transfer/file exchange between a defense contractor, primes, subcontractors, and suppliers. Sharetru Federal says it operates within a FedRAMP Moderate authorization boundary and uses U.S.-based data centers and U.S. personnel.
• Amazon Web Services AWS GovCloud (US) — Best if you want to build your own controlled transfer service rather than buy a finished file-transfer application. GovCloud restricts AWS access to U.S. persons and is designed to let customers architect ITAR-capable systems, but your organization remains responsible for configuring and operating the solution correctly.

What I would require

For an ITAR file-transfer platform, your procurement/security checklist should include:

• U.S.-only data storage and processing
• U.S.-person access to ITAR data and administrative functions, where required by your export-control determination
• Strong encryption in transit and at rest, preferably validated cryptographic modules
• MFA, RBAC/least privilege, and preferably conditional access
• Detailed, tamper-resistant audit logs for upload, download, sharing, and administrative access
• Ability to restrict sharing to specifically authorized users/organizations
• Data-loss-prevention and download controls
• Customer-controlled encryption keys or an equivalent strong key-management model
• Secure external sharing without requiring recipients to use consumer cloud storage
• Contractual language covering subcontractors, support personnel, data location, and incident handling
• Evidence that the specific deployment/configuration, not merely the vendor's infrastructure, satisfies your ITAR obligations
• Alignment with NIST SP 800-171/CMMC/DFARS if the same environment also handles CUI

One especially important point: FedRAMP authorization alone does not make a system ITAR compliant. The AWS documentation makes this explicit, and the vendor's claims need to be evaluated against your particular ITAR data, users, contracts, and workflow.

My shortlist

If I were narrowing this to three for a typical aerospace/defense contractor:

1. Sharetru — best fit when the core requirement is straightforward regulated file transfer.
2. Virtru — best when you need persistent protection and controlled sharing of files across organizational boundaries.
3. FileCloud FedRAMP High — best when you want a full enterprise file-sharing/content-management environment with extensive governance.

If you tell me your company size, approximate file sizes/volume, whether recipients are subcontractors/customers/government agencies, cloud vs. on-prem preference, and whether you also need CMMC Level 2, I can narrow this down to the best 2–3 solutions and compare ITAR/U.S.-person controls, encryption, auditability, deployment, and expected cost.

When looking for an ITAR (International Traffic in Arms Regulations) compliant file transfer solution, the core requirement is preventing unauthorized access or export of defense-related technical data to non-U.S. persons . This means the platform must feature strict data residency (U.S. hosted/AWS GovCloud), robust access controls, FIPS-validated encryption, and ideally, end-to-end encryption with U.S. person key control.

Top ITAR-compliant file sharing and transfer solutions include:

• FileCloud: Offers options to self-host or deploy on AWS GovCloud . It includes a dedicated ITAR compliance center with FIPS 140-2 encryption, comprehensive audit rules, and granular access policies to ensure data stays under U.S. control.
• Virtru: Best if your ITAR-regulated transfers happen heavily through email and direct attachments. Virtru provides data-centric protection with FIPS-validated cryptography, granular access controls (revoke/expire), and a Private Keystore option that gives your organization absolute control over encryption keys.
• Managed File Transfer (MFT) & SFTP Platforms: Traditional enterprise MFT solutions (such as GoAnywhere MFT or SFTP servers hosted in sovereign government clouds) handle secure transport-layer encryption (TLS/SSH) and detailed audit logs. Note: Standard MFT tools only encrypt data in transit; you must ensure they are paired with proper endpoint controls or file-level encryption if the data requires post-transfer restriction.

Key features required for ITAR file transfer compliance:

• U.S. Data Sovereignty: Hosted exclusively within the United States, typically on FedRAMP Moderate/High or AWS GovCloud infrastructure.
• Access Restrictions: Verification and restriction capabilities to ensure only authorized U.S. persons can access the technical data.
• FIPS Cryptography: Utilization of FIPS 140-2 or FIPS 140-3 validated encryption algorithms for data at rest and in transit.
• Comprehensive Audit Trails: Detailed logging of who accessed, downloaded, or shared any sensitive technical files.

To help narrow down the ideal platform for your organization, let me know:

• Do you need an email-attachment encryption layer or a dedicated portal/cloud storage workspace?
• Do you prefer a SaaS/GovCloud deployment or an on-premises/self-hosted infrastructure?

Complying with the International Traffic in Arms Regulations (ITAR) means that any technical data under the U.S. Munitions List (USML) must be safeguarded from access by foreign nationals—both physically and digitally . A secure file transfer solution for ITAR must enforce strict data residency (U.S.-based servers only), FIPS 140-2/3 validated encryption (at rest and in transit), granular access controls, and comprehensive, immutable audit logs.

Top-tier secure file transfer and collaboration platforms tailored for ITAR and defense industrial base (DIB) compliance include:

4. Fortra's GoAnywhere MFT
   • Overview: An enterprise-grade Managed File Transfer (MFT) solution that automates and secures file movements across systems, employees, and external partners.
   • Key Features: Centralized administration, detailed audit trails, automated encryption, and robust access controls suited for defense contractors managing strict supply chain logistics. Check out options on GoAnywhere Data Security Solutions.

To help narrow down which solution fits best, could you share:

• Are you looking for a cloud-hosted (FedRAMP/GovCloud) or an on-premises/self-hosted infrastructure?
• Do you primarily transfer files via automated server-to-server (MFT) or user-to-user collaboration/email?

Yes. For ITAR-controlled technical data, I would focus on U.S.-hosted infrastructure, U.S.-person access controls, strong encryption, detailed audit logs, and administrative controls that prevent accidental foreign-person access. One important caveat: there is no official “ITAR-certified” software or cloud service; ITAR compliance is ultimately an organizational/legal obligation, and the provider's controls are only part of the solution. AWS explicitly makes this distinction for GovCloud.

Strong options to evaluate

• box.com — A mature enterprise option. Box states that its platform supports ITAR, NIST 800-171, FedRAMP High, and DoD IL4 requirements. Its security capabilities include encryption in transit/at rest, access controls, and customer-controlled encryption keys through Box KeySafe. Box Box Best for: organizations wanting broad collaboration/document-management capabilities in addition to secure transfer.
• virtru.com — Particularly interesting if you need controlled sharing of ITAR technical data rather than just a conventional file-transfer server. Virtru advertises U.S. hosting, FIPS 140-2 validated encryption, granular access controls, customer-hosted keys, and FedRAMP authorization. Virtru Virtru Best for: persistent encryption and tightly controlled sharing with suppliers/partners.
• sharetru.com — More directly focused on secure file transfer/file sharing for CUI and ITAR. Sharetru Federal describes a FedRAMP Moderate-authorized environment designed specifically for regulated data, with access controls and audit trails. ShareTru Best for: a dedicated secure file-transfer experience rather than a general-purpose collaboration platform.
• regdox.com — Positions its ITAR solution around U.S.-only hosting and U.S.-person administration/support, with auditing and monitoring. Regdox Best for: organizations where U.S.-person operational access is a particularly important requirement.

What I would require in an RFP

Don't accept a vendor's statement that it is simply “ITAR compliant.” Ask for written confirmation of:

1. U.S.-only data storage and processing, including backups and disaster recovery.
2. U.S.-person-only administrative/support access, if your export-control determination requires it.
3. FIPS-validated cryptography appropriate to your security requirements.
4. Encryption at rest and in transit, preferably with customer-controlled keys.
5. MFA, RBAC, least privilege, and granular sharing controls.
6. Complete audit logs covering uploads, downloads, sharing, access attempts, administrative activity, and permission changes.
7. Controls preventing users from sharing ITAR files with unauthorized foreign persons.
8. Data-retention, deletion, backup, and incident-response procedures.
9. Alignment with NIST SP 800-171/CMMC/DFARS if the ITAR data is also CUI.
10. A contractual commitment covering subprocessors and support personnel, not merely the primary hosting location.

My shortlist

If this is for a defense contractor, I'd start with Sharetru, Virtru, and Box and evaluate them against your particular ITAR/CUI workflow. If you need something highly customized, building an MFT/file-transfer service in AWS GovCloud (US) is another route; AWS says GovCloud is designed to help customers architect ITAR-compliant systems, while emphasizing that the customer remains responsible for compliance.

If you tell me (a) approximate file sizes/volume, (b) number of users, (c) whether external suppliers need access, (d) whether the data is also CUI/CMMC-controlled, and (e) whether you need SFTP/API automation, I can narrow this to the 2–3 best-fit solutions and compare pricing, architecture, ITAR controls, and deployment options.

Yes. For ITAR-controlled technical data, I’d focus on end-to-end encryption, U.S. data residency, strict access controls, audit logging, and—depending on the architecture—U.S.-person restrictions.

One important nuance: there is no standalone “ITAR-certified” file-transfer product. ITAR compliance depends on your overall compliance program, data classification, authorization for each transfer, recipients, and how the service is configured. Microsoft explicitly makes this distinction, and AWS similarly places compliance responsibilities on the customer.

Strong options to evaluate

What I'd require in an RFP

For an ITAR file-transfer system, require the vendor to document:

• Encryption: end-to-end encryption and appropriate FIPS-validated cryptography.
• Key ownership: ideally customer-controlled keys, or a clear explanation of who can access them.
• Data residency: U.S.-only storage, backups, replicas, logs, and disaster-recovery copies where required by your compliance architecture.
• Personnel access: whether vendor administrators/support personnel are U.S. persons and how access is controlled.
• Recipient controls: ability to restrict sharing to specifically authorized people/organizations.
• MFA and RBAC: preferably with granular, per-file or per-project permissions.
• Audit trail: immutable/downloadable records of uploads, downloads, sharing, permission changes and administrative access.
• Retention/deletion: documented handling of backups and deleted files.
• Export-control workflow: ability to associate transfers with authorization, recipient, classification, and approval records.

Also, don't assume that simply using encryption makes every transfer permissible. The regulatory treatment can depend on the precise circumstances and applicable rules. For example, U.S. export-control regulations contain specific provisions concerning encrypted unclassified technology/software, including requirements concerning end-to-end encryption and cryptographic controls.

My shortlist: If you want a turnkey secure-transfer product, I'd start with Virtru and PreVeil. If you need a controlled document repository/data room, RegDOX is worth evaluating. If you're building a larger controlled environment, AWS GovCloud or Azure Government with a purpose-built transfer application gives you considerably more architectural control.

If you tell me (1) approximate file sizes, (2) number of users, (3) whether recipients are U.S. persons, (4) whether you need FedRAMP/CMMC as well, and (5) your approximate budget, I can narrow this to the best 2–3 choices and compare pricing, security architecture, and deployment effort.

Complying with ITAR (International Traffic in Arms Regulations) means ensuring that unclassified technical data related to defense articles and services is never exposed to foreign persons—either in transit, at rest, or via cloud vendor infrastructure.

Under ITAR's encryption carve-out rule (22 CFR § 120.54), transferring or storing technical data digitally is compliant and not considered an export if robust, end-to-end encryption is used and decryption keys are kept completely out of the hands of foreign nationals or unauthorized cloud providers.

Top secure file transfer and sharing solutions tailored for ITAR compliance include:

• Kiteworks Secure MFT : Built specifically for defense contractors and government agencies, Kiteworks utilizes a hardened virtual appliance with a zero-trust architecture, FIPS 140-2/3 validation, and comprehensive audit logging. It unifies managed file transfer, secure email, and file sharing while strictly controlling U.S. person-only access.
• FileCloud : Offers dedicated ITAR compliance tracking via its built-in Compliance Center. FileCloud can be self-hosted on-premises or deployed securely inside AWS GovCloud , giving your organization total sovereignty over data residency, AES-256 encryption at rest, and granular access rules.
• PreVeil : Widely used by the Defense Industrial Base (DIB), PreVeil leverages end-to-end encryption using FIPS-validated cryptography where only the authorized sender and receiver possess the keys. It aligns directly with ITAR § 120.54 encryption carve-outs and layers cleanly over existing IT infrastructure without requiring an expensive cloud overhaul.
• Virtru Secure Share : Provides data-centric, end-to-end protection with FIPS-validated encryption and private key management options. It allows you to add an ITAR-compliant security layer on top of existing productivity tools (like Microsoft 365 or Google Workspace) with instant file revocation and access controls.

To help narrow down the ideal platform for your workflow, could you share:

• Do you prefer an on-premises/self-hosted deployment or a cloud-based (SaaS / GovCloud) service?
• Are you primarily doing system-to-system automated transfers (MFT) or user-to-user file sharing and collaboration?

Yes. For ITAR-controlled technical data, I’d focus on solutions that can demonstrate—not merely claim—U.S. data residency, U.S.-person administrative access, strong encryption, access controls, and comprehensive audit logging.

Strong options to evaluate

My first choice for a straightforward managed file-transfer requirement would be Kiteworks Secure Gov Cloud. It is particularly relevant if you need SFTP, browser-based sharing, APIs, external collaboration, audit trails, and centralized policy enforcement rather than simply cloud storage.

Important ITAR caveat

There isn't really an "ITAR-certified file-transfer product" that automatically makes your organization ITAR compliant. ITAR compliance is an organizational/export-control obligation, and the technology is one part of your compliance program. For example, AWS specifically notes that organizations must control unintended exports by restricting access to protected data to U.S. persons and keeping the protected data physically in the United States.

I'd therefore require a vendor to document at least:

• 100% U.S. data residency for ITAR data, including backups and disaster recovery.
• U.S.-person-only access to the relevant systems and support functions.
• Encryption in transit and at rest, preferably using validated cryptographic modules where applicable.
• MFA, RBAC/least privilege, and strong identity integration.
• Detailed, tamper-resistant audit logs covering downloads, uploads, sharing, administrative access, etc.
• Ability to prevent sharing with unauthorized foreign persons.
• Clear subprocessors and supply-chain disclosures.
• Incident-response and breach-notification procedures.
• Contractual terms addressing ITAR-controlled data.
• Evidence showing exactly which product/service components are inside the compliance boundary.

Also, don't assume that FedRAMP certification by itself equals ITAR compliance. FedRAMP addresses federal cloud security authorization; whether a particular implementation satisfies your ITAR obligations depends on the actual architecture, personnel access, data flows, and your organization's export-control program. FedRAMP itself notes that the specific agency/use case determines whether and how FedRAMP applies.

If you tell me (1) number of users, (2) typical file sizes, (3) whether you need SFTP/API or just web sharing, (4) whether customers/vendors outside your company need access, and (5) whether you also need CMMC/NIST 800-171, I can narrow this to 2–3 solutions and compare security, ITAR suitability, deployment model, and likely cost.

When looking for a secure file transfer solution that complies with International Traffic in Arms Regulations (ITAR), you must meet strict criteria under 22 CFR § 120.54 (the ITAR encryption carve-out). To prevent an encrypted file transfer or storage from legally constituting a foreign "export," the solution generally requires end-to-end encryption (FIPS 140-2/3 validated), U.S. data residency , and exclusive control over decryption keys so that cloud providers or foreign nationals cannot access the plaintext.

Top ITAR-compliant file sharing and transfer solutions include:

• PreVeil Drive - Best for simplified and cost-effective compliance. It uses end-to-end encryption with FIPS-validated cryptography where decryption keys are never shared with the vendor, satisfying ITAR encryption carve-outs while layering cleanly over existing IT infrastructure.
• Virtru Secure Share - Best for data-centric and email-attached file transfers. Virtru provides persistent, client-side encryption and integrates with private keystores (via the Private Keystore option) to ensure your organization retains sole custody of the keys.
• FileCloud - Best for enterprise content management and self-hosted or GovCloud deployments. FileCloud features an dedicated ITAR compliance center dashboard, supports FIPS 140-2 encryption, and can be self-hosted on AWS GovCloud or deployed on-premises for complete data sovereignty.
• Kiteworks MFT - Best for heavy-duty Managed File Transfer (MFT) pipelines. It provides rigorous access controls, tracking, auditing, and secure routing specifically tailored for defense contractors adhering to DFARS and ITAR.

To help narrow down the best choice for your organization, let me know:

• Are you looking for a cloud/SaaS overlay (like Virtru/PreVeil) or a self-hosted/on-premise managed file transfer system (like FileCloud/Kiteworks)?
• Do you need to integrate this with an existing productivity suite like Microsoft 365 or Google Workspace?

Yes. For ITAR-controlled technical data, I’d focus on U.S.-based hosting, U.S.-person administrative/support access, strong encryption, granular access controls, and auditable transfer logs—not simply a vendor saying “secure” or “FedRAMP compliant.” ITAR compliance is ultimately about how your organization handles controlled technical data and export controls, so the product alone does not make an organization compliant.

Strong candidates

My shortlist

For simple secure transfers: I'd start with Virtru.

For a full document repository/collaboration platform: I'd evaluate FileCloud and Box.

For particularly strict U.S.-person/data-sovereignty requirements: I'd put RegDOX and a self-hosted FileCloud deployment high on the list.

One important distinction: FedRAMP authorization ≠ automatic ITAR compliance. You need to verify the exact service/environment, where data and backups reside, who can administer it, where support personnel are located, encryption/key-management architecture, and whether subcontractors have access. Virtru, for example, explicitly describes its ITAR offering in terms of preventing non-U.S. access and customer-controlled key management.

If you tell me (1) approximate number of users, (2) typical file sizes, (3) whether you need SFTP/API automation or just a web portal, (4) whether all administrators must be U.S. persons, and (5) your budget, I can narrow this to the 3 best options and compare pricing, ITAR/CMMC/FedRAMP posture, encryption, U.S.-person access, audit logs, and deployment model.

When looking for a secure file transfer solution that complies with International Traffic in Arms Regulations (ITAR), the primary requirement is preventing unauthorized access—specifically by non-U.S. persons—to unclassified defense-related technical data.

Under the ITAR encryption carve-out (22 CFR§§§ 120.54(a)(5)), transmitting unclassified technical data is not deemed an export if it utilizes end-to-end, FIPS-validated encryption and the decryption keys are never accessible by foreign persons or cloud providers.

Top ITAR-compliant file transfer and storage solutions feature specific architectures to meet these rigorous demands:

• Kiteworks MFT : Highly regarded for defense and government contracting, it provides unified governance, comprehensive audit logging, FIPS 140-3 validated encryption, and U.S.-only data residency options designed to align with strict compliance frameworks like CMMC and FedRAMP.
• PreVeil : Offers client-side, zero-trust end-to-end encryption for file sharing (PreVeil Drive) and email. Because data is encrypted and decrypted strictly on user endpoints using customer-controlled keys, the provider cannot see the data, satisfying ITAR data-sharing boundaries.
• FileCloud : Can be self-hosted or deployed on AWS GovCloud. It includes a dedicated ITAR compliance center, granular access management, and FIPS-validated encryption, allowing defense contractors to maintain total physical and technical control over data sovereignty.
• Sharetru : Offers FedRAMP-authorized and compliant cloud-based managed file transfer (MFT) environments supporting SFTP, FTPS, and secure web portals that restrict access paths and manage data boundaries specifically for defense supply chains.
• Virtru : An overlay option that integrates with existing environments (like Microsoft 365 or Google Workspace) to apply client-side FIPS-validated encryption and fine-grained access control (such as disable forwarding or immediate revocation) directly to files and emails.

To help narrow down the ideal platform for your organization, let me know:

• Do you prefer an on-premises, hybrid, or cloud-hosted (GovCloud) deployment?
• Are you primarily looking for system-to-system automated Managed File Transfer (MFT) or user-to-user/partner file sharing?
