AI CONTRACT REVIEW · INTEL TDX vs IRONCLAD AI ASSISTANT

VoltageGPU vs Ironclad

VoltageGPU is not a CLM. Ironclad is the Contract Lifecycle Management platform; VoltageGPU is the confidential AI review agent that runs inside or alongside it. The fair comparison is VoltageGPU Contract Analyst vs Ironclad AI Assistant, not vs the whole Ironclad platform.

Ironclad runs the contract lifecycle, repository, approvals, e-signature, Salesforce hooks. Its AI Assistant runs on OpenAI and Anthropic, which means every clause your reviewers paste into the assistant leaves the CLM and lands on a US-hosted LLM data plane. VoltageGPU replaces that AI layer with a Contract Analyst agent running inside Intel TDX, on a $349/mo subscription, live in two minutes.


Headline pricing

Monthly plan price by tier. VoltageGPU plans run on Intel TDX with cryptographic attestation; the agent and its memory are sealed in hardware. ", " means the competitor does not publish a comparable per-month tier (annual contract / RFP only). Plans stay in sync with /pricing.

Ironclad solves CLM. We solve the AI-review work inside it.

Ironclad is a Contract Lifecycle Management platform. It owns the workflow that takes a contract from draft, through approvals and redlining, into signature, and into a permanent repository. That platform is good at what it does, the integrations into Salesforce, Workday, and NetSuite are real, and the enterprise procurement track record is genuine. The CLM is not the thing we are comparing against.

The thing we are comparing against is the AI feature set bolted on top: Ironclad AI Assistant, clause extraction, redlining suggestions, repository question-answering. That layer does not run inside Ironclad. It runs on OpenAI and Anthropic, called from the Ironclad backend on AWS US-East. Every clause your reviewers paste into the assistant, every contract the system summarises, every question your team asks the repository, that payload traverses a US-hosted large-language-model data plane operated by a third party. Ironclad provides no hardware attestation that the LLM cannot retain that payload, and neither OpenAI nor Anthropic publishes a TDX-rooted attestation primitive for their enterprise endpoints today.

VoltageGPU is the replacement for that AI layer. The Contract Analyst agent runs on Qwen3-32B-TEE, Qwen3-235B-TEE, or DeepSeek-V3.2-TEE inside an Intel TDX guest with AES-256 memory encryption and an Intel DCAP attestation quote produced for every session. There is no third-party LLM provider on the data path. The contract text never leaves the trust boundary. The operator, VOLTAGE EI in France, is mathematically constrained from reading workload memory, and the cryptographic evidence to that effect is verifiable offline by any auditor against the Intel root certificate.

The honest framing is: if you already run Ironclad and you do not want your contract review work travelling through US-hosted LLMs, you do not need to rip out the CLM. You disable the Ironclad AI features, point your workflow at the VoltageGPU Contract Analyst via webhooks or our OpenAI-compatible API, and feed the TDX-attested review back into the Ironclad repository. The CLM stays. The AI moves into the enclave.


What hardware seal changes for contract review.

A lawyer drafting a contract is producing privileged work product. An M&A team running due diligence is handling material non-public information. A procurement team reviewing a vendor master services agreement is touching commercial terms that competitors would pay for. None of these workloads are abstract privacy questions; they are concrete legal-exposure questions with defined statutory and bar-association rules attached.

Sending that work product to a US-hosted LLM provider is not a checkbox failure. It is a privilege-exposure question that the courts have not finished answering. The 2024 Mata v Avianca opinion and the subsequent state-bar guidance from California, New York, and the District of Columbia have made one thing clear: lawyers are responsible for understanding where the data they paste into an AI tool actually lands, who can read it, and under what jurisdiction it sits. "Our CLM has SOC 2" is no longer a sufficient answer when the AI feature inside that CLM is calling a third-party LLM under a separate data-processing posture.

Intel TDX changes the answer mathematically rather than contractually. The CPU encrypts the VM memory with AES-256 against a key the host cannot extract. The attestation quote, produced by Intel-rooted silicon for every confidential session, binds the workload memory contents to a configuration any verifier can re-check offline. The operator cannot bypass it, the cloud provider cannot bypass it, and a subpoena to the operator cannot produce decrypted memory because the operator does not possess it. For a privileged contract review, that is the technical measure the bar-association guidance is asking for. SOC 2 says "Ironclad has access controls." Intel TDX says "no operator, including Ironclad, can read the memory by design." Those are different categories of claim.

The same logic applies to GDPR Article 28 Data Processing Agreements signed under French law, to HDS-scoped patient-record review for clinics, and to PCI DSS scope reduction for fintech vendor onboarding. The European Data Protection Board has been explicit since 2024 that "the processor has SOC 2" does not constitute appropriate technical measures for high-risk personal data under Article 32. Hardware-rooted attestation is increasingly being named in the technical measures clause itself.


Where Ironclad wins, and where it does not.

Ironclad wins on the parts of the problem that are not AI. It wins on having a real contract repository with audit trail and versioning, on having a workflow engine that legal operations teams have already configured for their company, on having native integrations into Salesforce for sales-led contracts and into Workday for HR contracts, on having an e-signature flow that procurement teams already trust, and on having an enterprise sales motion that survives an RFP. If the buyer needs all of that and does not yet have a CLM, the conversation is between Ironclad, DocuSign CLM, Icertis, and Juro, and VoltageGPU is not in that conversation. We do not pretend to be.

Ironclad loses on three specific axes. First, on time-to-value: a typical Ironclad rollout is three to six months of implementation and change management, on top of a procurement cycle that usually adds another quarter. VoltageGPU Contract Analyst goes live in two minutes against an OpenAI-compatible API. Second, on AI architecture: Ironclad AI calls OpenAI and Anthropic on standard AWS US-East hosting. There is no enclave, no Intel TDX, no DCAP attestation, no hardware seal between the LLM and the cloud operator. Third, on price posture: Ironclad starts at $30K/year for entry-tier with a $5K-$25K implementation engagement bolted on, scales to $96K/year for mid-tier with $25K-$50K implementation, and runs $150K-$200K+/year at enterprise with $50K-$100K implementation. VoltageGPU is $349 / $1,199 / $3,499 per month with no implementation fee, no annual commit, no RFP, and a public price list.

The honest customer conversation is rarely "Ironclad or VoltageGPU." It is more often "Ironclad plus VoltageGPU" the CLM stays as the system of record, and the AI review work moves into the enclave. For customers who do not yet have a CLM and only need contract review (M&A diligence, vendor onboarding, compliance audits, RFP response), VoltageGPU on its own at $349/mo replaces the Ironclad AI Assistant feature directly without buying the surrounding platform.


FAQ

Can VoltageGPU replace Ironclad?

Honestly, no, not entirely. Ironclad is a Contract Lifecycle Management platform: repository, workflow, approvals, e-signature, integrations into Salesforce and Workday. VoltageGPU is an AI agent layer. If you need a contract repository plus workflow plus e-signature, you should keep Ironclad (or evaluate DocuSign CLM, Juro, or Icertis) and run our Contract Analyst alongside as the AI review layer. If you only need contract review work, M&A due diligence, vendor onboarding screening, compliance audits, RFP response analysis, and you do not need the surrounding CLM, then VoltageGPU at $349/mo replaces the Ironclad AI Assistant feature directly without buying the rest of the platform.

Does Ironclad AI run in a confidential enclave?

Not as of May 2026. The Ironclad AI feature set, clause extraction, redlining suggestions, repository question-answering, calls OpenAI and Anthropic from the Ironclad backend on AWS US-East. Neither OpenAI nor Anthropic publishes a hardware-rooted Intel TDX attestation primitive on their enterprise endpoints today. There is no DCAP quote a customer or auditor can verify offline against the Intel root. SOC 2 Type II and ISO 27001 certifications attest to policy and audit controls; they do not constitute the same category of guarantee as silicon-rooted memory encryption with cryptographic attestation per session.

What about Ironclad SOC 2 and ISO 27001?

Those are real certifications and they matter for procurement. They are not, however, in the same category of claim as hardware seal. SOC 2 Type II says "Ironclad has implemented documented access controls and the controls operated as described over the audit window." ISO 27001 says "Ironclad runs an information-security management system consistent with the standard." Both are valuable, both are policy-and-audit attestations, and both depend on humans following procedures. Intel TDX says "the silicon prevents the operator, including Ironclad, from reading workload memory, and any verifier can re-check the cryptographic evidence offline against the Intel root certificate without trusting our procedures at all." For privileged contract review under bar-association rules or GDPR Article 32 technical-measures scope, the second category is what regulators have begun to specifically require.

Pricing, Ironclad starts at $30K/year. What is the true total cost on our side?

Starter is $349/mo, which is $4,188/year, with one Contract Analyst agent, 3 seats, and 500 contract reviews per month. Professional is $1,199/mo, which is $14,388/year, with all 9 vertical agents, 10 seats, and 5,000 reviews per month. Enterprise is from $3,499/mo, which is from $41,988/year, with unlimited reviews, dedicated TDX nodes, and DeepSeek-V3.2-TEE reasoning. There is no implementation fee, no annual commit, no RFP, no procurement cycle. Cancel month-to-month. The full price list is public, no quote required to see the number.

Can I use VoltageGPU Contract Analyst with my existing Ironclad workflow?

Yes. The Contract Analyst agent exposes an OpenAI-compatible HTTP API at api.voltagegpu.com/v1 with the standard chat-completions and tool-calling shapes. You can call it from an Ironclad webhook on any workflow event (contract uploaded, version saved, approval routed), from Zapier as a no-code bridge, or from a custom script in your contract-management pipeline. The TDX-attested review comes back as a structured response that you write into the Ironclad repository as a clause comment, an approval-stage attachment, or a metadata field. Your existing Ironclad workflow keeps running; the AI review work just stops travelling through OpenAI and starts travelling through Intel TDX inside our enclave.
