Procurement checklist for neural MT vendors focused on FedRAMP, security, quality metrics, and integration readiness for government contracts.

Hook: Procurement teams face a hard truth — translation failures risk contracts

If you buy neural machine translation (MT) for government clients and your vendor can't prove security, compliance, or integration readiness, you won't just lose efficiency — you could lose a contract. Procurement teams in 2026 must evaluate neural MT vendors with the same rigor they use for cloud or analytics platforms. This article gives a practical, government-focused vendor evaluation checklist that prioritizes FedRAMP, security, quality metrics, and integration readiness so you can procure confidently.

The context: why 2026 is different

Late 2025 and early 2026 brought two clear market shifts that change how procurement teams must evaluate neural MT:

More AI vendors are pursuing and acquiring FedRAMP-approved platforms. High-profile moves — including BigBear.ai's acquisition of a FedRAMP-approved AI platform in late 2025 — signal a market pivot toward compliance-ready offerings.
Regulators and agencies are demanding stronger evidence of secure model behavior: NIST's AI Risk Management frameworks and government-specific controls around CUI, data residency, and supply chain security are now baseline expectations.

That means your checklist must combine traditional procurement items (SLAs, pricing) with technical verification (SSP, KMS, model training policy) and programmatic proof (acceptance tests, pilot outcomes, ROI/TCO). Below is a pragmatic, step-by-step guide you can apply to any RFx or vendor shortlist.

Top-line checklist (one-page view)

Security & Compliance: FedRAMP authorization level, SSP, SOC 2, ISO 27001, CMMC readiness
Quality Metrics & Acceptance: COMET/chrF/BLEU baselines, human post-edit tests, HTER targets
Integration Readiness: APIs, XLIFF/TF support, CMS connectors, CI/CD workflows
Pricing & TCO: per-word vs subscription, inference compute, training costs, compliance audit costs
Legal & Data Handling: data ownership, model training opt-out, breach notification
Operational Support & Roadmap: sandbox, support SLAs, roadmap for model updates and FedRAMP continuity

1) Security & Compliance — the non-negotiables

For government contracts, security is the gating factor. Do not move forward without documentary proof.

Ask for these documents and capabilities

FedRAMP authorization: specify the authorization level required (Moderate / High). Request the authorization letter and FedRAMP Marketplace listing.
System Security Plan (SSP): review the SSP for the service implementation, boundary, and controls mapped to NIST SP 800-53 Rev. 5.
Plan of Actions & Milestones (POA&M): check for outstanding vulnerabilities or compensating controls.
SOC 2 Type II / ISO 27001: complementary attestations that cover operational controls and process maturity.
Encryption & Key Management: confirm FIPS 140-2/3 compliant cryptography, BYOK (Bring Your Own Key), HSM support, and keys under customer control where required.
Data handling for CUI/PHI: procedures for identifying, segregating, and deleting Controlled Unclassified Information (CUI); retention and deletion policies.
Supply chain & SBOM: software bill of materials and third-party dependencies; vulnerability disclosure policy.
Incident response & logging: SIEM integration, audit trails, evidence retention, and breach notification SLA.
Export controls & contractual clauses: ITAR or other export restrictions if your content is regulated.

Practical evaluation steps

Require FedRAMP marketplace proof in the RFP and pre-qualify vendors by authorization level.
Run a security review of the SSP and validate POA&M status with the vendor's FedRAMP representative.
Arrange an on-site (or virtual) security walk-through with your ISSO/CISO to validate isolation, network segmentation, and logging.

2) Quality & performance — metrics that matter for government content

Raw BLEU scores are insufficient — government content demands fidelity, correct handling of legal terms, dates, numbers, and procedure steps. Your evaluation must combine automatic metrics with realistic human assessments.

Essential quality metrics and tests

Automatic metrics: COMET (learned metric), chrF, BLEU for baselining. Ask vendors to provide scores on your in-domain test set rather than public corpora.
Human evaluation: Direct Assessment (DA) and Post-Editing Time (PET). Use multiple raters and bias controls.
Task success metrics: Information retrieval accuracy, decision correctness in forms, and comprehension scores for instruction manuals.
Error taxonomy: measure named entity accuracy, numeric/date precision, legal term correctness, and hallucination rate.
Post-editing effort (PE/HTER): measure percentage of characters/words changed and time per segment by a qualified linguist.

Design a real acceptance test

Assemble a 1,000–2,000 segment test set representative of the contract scope (policy docs, SOPs, legal clauses, public-facing content).
Run blind A/B comparisons against your baseline (current MT or human translation) with human raters scoring adequacy and fluency.
Set acceptance criteria: for example, target a post-editing effort reduction of 40–60% compared to baseline, or HTER < 20% depending on domain risk.
Require vendor to demonstrate glossary enforcement, terminology recall, and TM leverage on the test set.

3) Integration readiness — make sure it fits your stack

Even the best MT is unusable if it doesn't integrate with CMS, developer workflows, or translation management systems used by your agencies.

API & deployment checklist

API protocols: REST and gRPC with OpenAPI specs, rate limits, and sample clients.
File formats: XLIFF 2.0, TMX import/export, support for HTML, JSON, and Office file types without losing markup.
CMS & TMS connectors: WordPress, Drupal, Adobe Experience Manager, Smartling, memoQ, Lingotek, etc.
CI/CD & DevOps: CI hooks, webhooks, Git/GitHub/GitLab connectors, and SRE runbooks for auto-deploys and rollback.
Hybrid & on-prem options: container images, Kubernetes Helm charts, or private VPC deployments for air-gapped environments.
SDKs & developer docs: Python, Node, Java SDKs, usage examples, and production-grade latency benchmarks.

Integration acceptance tests

Require a short pilot: a sandbox deployment that demonstrates end-to-end publishing from source CMS to translated site in your staging environment.
Measure latency and throughput with representative traffic (SLA: median latency, p95/p99, and max throughput targets).
Test failover: confirm retries, queueing behavior, and data durability if the translation endpoint is unavailable.

4) Pricing, ROI, and TCO — what procurement really needs to know

Neural MT pricing varies widely. A complete TCO includes more than per-word rates.

Pricing components to compare

Per-word or per-character inference pricing vs subscription or seat-based pricing.
Compute surcharges for peak throughput, custom model fine-tuning, or on-prem resources.
Data migration & TM import fees, glossary setup, and initial customization.
Security & compliance costs (FedRAMP artifacts, audit support, SSP updates) — often incremental.
Support & SLA tiers: 24x7 support, dedicated engineering hours, or managed services pricing.
Post-editing costs: ongoing linguistic QA and human editors; measure expected editing hours per 1,000 words post-deployment.
Exit costs: data export fees, TM export, and decommissioning assistance.

Sample TCO checklist (build your spreadsheet)

One-time: integration engineering, data prep, TM migration, fine-tuning — estimate in person-days and dollars.
Recurring: per-word inference + post-editing + support subscription.
Compliance overhead: annual FedRAMP monitoring, audit support hours, vulnerability remediation.
Opportunity costs: time-to-publish improvements, international engagement gains (use concrete traffic & conversion uplift estimates).

5) Legal, policy, and data use — protect intellectual property and citizen data

Contract language governs risk. Negotiation points you must include:

Data ownership: vendor must not claim ownership or indefinite access to customer content.
Model training opt-out: ability to prevent vendor from using your content to further train or fine-tune shared models.
Data deletion guarantees: timebound deletion policies and certification of deletion for backups.
Indemnification & liability caps: align these with agency risk posture.
Audit rights: contractual rights to audit compliance artifacts, SSPs, and logs during the contract term.

6) Operational readiness & vendor maturity

Procure for the long term. Assess vendor resilience and roadmap.

Support SLAs, escalation paths, and named points of contact.
Release cadence for models and transparency about changes that affect translation output.
Evidence of continuous monitoring for hallucination, bias, and drift — require red-team reports or synthetic test suites.
Customer references in government or regulated sectors; ask for two references with similar technical stacks.

Practical procurement playbook — step-by-step

Issue a pre-qualification questionnaire (PQQ) that filters vendors by FedRAMP authorization level and basic security attestations.
Run a two-week technical sandbox pilot using a representative content bundle. Require logs, metrics, and a small human evaluation panel.
Request the SSP and perform a security review. If FedRAMP is pending, require a clear POA&M and timeline.
Negotiate contract clauses for data ownership, training opt-out, and exit assistance before awarding.
Measure pilot results against acceptance thresholds: quality metrics, SLA performance, integration stability, and TCO projection.
Award a phased contract with go/no-go gates tied to measurable outcomes and independent QA reviews.

Red flags that should stop a purchase

Vendor refuses to provide an SSP or FedRAMP artifacts.
No option to opt out of having your content used for model training.
Opaque pricing or unlimited surge fees that make TCO unpredictable.
Poor API documentation, no sandbox, or inability to demonstrate integration with your CMS/TMS.
High hallucination rates on topic-specific tests or failure to meet human post-edit acceptance targets.

What BigBear.ai's move signals to buyers

BigBear.ai's late-2025 strategic move to acquire a FedRAMP-approved AI platform is emblematic: vendors are consolidating compliance capabilities to win government work. As procurement teams, treat FedRAMP not as a checkbox but as a program governance requirement — verify the vendor's ability to maintain authorization through software updates, supply chain changes, and cloud provider shifts.

Tip: FedRAMP authorization is tied to a specific system design and vendor implementation. If a vendor says "we're FedRAMP" but cannot produce the SSP and authorization artifacts for the exact product you will use, treat that as unproven.

Future-proofing and 2026 trends to watch

Model watermarking and provenance: expect regulation and procurement clauses requiring provable content provenance to detect synthetic manipulations.
Hybrid and edge deployments: increased demand for private VPC or on-prem inference to satisfy data residency in high-security agencies.
Stronger regulatory alignment: NIST AI RMF adoption and enhanced agency-specific guidance will shape contract terms and audit expectations.
Performance-based procurement: more RFx processes will require proof of operational outcomes (e.g., time-to-market, reduction in post-editing hours) rather than feature lists alone.

Actionable takeaways (one-minute checklist)

Only shortlist vendors that provide FedRAMP artifacts for the exact product you will use.
Run a 2–4 week pilot with your in-domain content and human raters to measure post-editing effort and task success.
Insist on contractual model training opt-out and BYOK-enabled key management.
Compare TCO across per-word, compute, and compliance costs — include exit costs.
Include go/no-go gates in the contract tied to measurable quality and integration outcomes.

Final example: Minimum acceptance criteria template

FedRAMP authorization: Moderate (or High if CUI risk dictates).
Quality: vendor COMET on our test set within X% of human baseline and HTER < 20% (adjust per domain).
Integration: successful automated transfer of 5,000 sample segments via XLIFF with glossary enforcement.
Latency/SLA: median latency < 300 ms; 99.9% uptime for production endpoint.
Legal: model training opt-out and data deletion certification within 30 days of request.
