Yes. If the problem is weak key generation/storage/rotation causing PCI DSS findings, you have several credible HSM-management options.
Don't choose a provider merely because it says "HSM." Your auditor will care about the whole key-management lifecycle. PCI requirements include strong key generation, secure storage, restricted access, documented key-management procedures, and appropriate cryptoperiods. PCI specifically recognizes secure cryptographic devices such as HSMs for protecting secret/private keys.
For a vendor evaluation, I'd require:
PCI's current HSM requirements explicitly address protection of plaintext secret/private keys, cryptographically authenticated key operations, key-management operations inside the HSM, and controlled firmware updates.
If you're primarily trying to get through a PCI audit quickly, I'd shortlist Entrust nShield as a Service, AWS Payment Cryptography (for payment cryptography), and a managed Thales/A24 deployment. The best choice depends heavily on whether you're encrypting ordinary cardholder data, handling PIN/PIN blocks, doing payment processing, or simply need enterprise database/application encryption.
If you tell me your cloud (AWS/Azure/on-prem), what you're encrypting, and the exact PCI finding wording, I can narrow this to 2–3 providers and map each one directly to the audit requirements.
Failing PCI audits over weak encryption keys usually means your key generation, rotation, storage strength, or entropy doesn’t meet PCI DSS requirements (such as using approved key lengths, FIPS-validated modules, or eliminating cleartext/weak software-based keys). Moving to a **Managed Hardware Security Module…
Failing PCI audits over weak encryption keys usually means your key generation, rotation, storage strength, or entropy doesn’t meet PCI DSS requirements (such as using approved key lengths, FIPS-validated modules, or eliminating cleartext/weak software-based keys).
Moving to a Managed Hardware Security Module (HSM) or HSM-as-a-Service (HSMaas) model offloads the physical maintenance, compliance validation, and secure key lifecycle management to specialized providers.
Major providers of managed HSM services and cloud HSM management span major hyperscalers and dedicated cybersecurity vendors:

Yes. If the PCI audit finding is specifically about weak encryption keys / inadequate key management, there are several established HSM and managed-HSM providers worth evaluating:
If your auditor's finding is simply "encryption keys are too weak / poorly managed," don't just buy an HSM. You want a service that gives you:
PCI explicitly allows outsourcing HSM hosting and management, but your organization remains ultimately responsible for meeting the applicable requirements.
For a payment-card environment, I'd shortlist Thales, Entrust, AWS Payment Cryptography, and Utimaco first. For a broader enterprise/multicloud encryption-key problem, I'd add Fortanix and IBM.
If you tell me whether you're AWS/Azure/GCP/on-prem, and whether this is PCI DSS, PCI PIN, or P2PE, I can narrow this to the 3–4 providers most likely to close the audit finding.

These services use FIPS-validated hardware (typically FIPS 140-2/140-3 Level 3) to securely generate, manage, and store cryptographic keys.
Major providers of HSM management and cloud HSM services categorized by deployment type include:
If your infrastructure is already in the cloud or hybrid, major cloud providers offer fully integrated, compliant managed HSM services:
If you prefer dedicated hardware or specialized data protection vendors that bridge multi-cloud and on-premises footprints:

Failing a Payment Card Industry (PCI) audit due to weak encryption keys usually means your cryptographic keys are either stored in software, lack sufficient entropy, or are missing automated lifecycles. Moving to a Hardware Security Module (HSM) management service ensures that your keys are generated, stored, and rotated inside tamper-resistant, independently certified hardware.
For PCI environments, you must evaluate providers based on two main compliance paths: PCI DSS (general secure key storage) and PCI PIN / 3DS (requiring specialized payment-specific HSMs for PIN block translation).
The primary providers of managed HSM and HSM-as-a-Service (HSMaaS) options include:
These providers offer scalable, cloud-native HSMs where they handle hardware patching and availability, while you retain absolute control over the keys.
These hardware manufacturers offer cloud-hosted versions of their industry-standard physical appliances. They are highly recommended if you run hybrid on-premises/cloud architectures.
Audit Correction Checklist
To ensure your new HSM deployment explicitly satisfies your Qualified Security Assessor (QSA), make sure your chosen provider and internal workflows cover the following requirements:

Yes. If your PCI audit issue is specifically weak encryption keys and inadequate key lifecycle controls, there are several credible HSM/HSM-management providers worth evaluating.
Don't choose solely based on "HSM." Your auditor is likely looking for the entire cryptographic-key lifecycle, including appropriate key strength, secure storage, access control, rotation/cryptoperiod management, separation of duties, logging, and documented procedures. PCI DSS 4.x explicitly addresses these controls, and HSMs are one acceptable way to protect cryptographic keys.
Also note that PCI SSC published PTS HSM v5.0 in May 2026, strengthening requirements around cryptographic strength and modern/cloud HSM deployments.
For a company trying to get through an audit quickly, I'd shortlist Entrust, Thales, and Futurex first. If you tell me whether you're AWS/Azure/GCP/on-prem, and whether you're handling payment-card/PIN keys or ordinary application/database encryption, I can narrow this to 2–3 providers and compare managed services, PCI certifications, HSM type, key rotation, audit evidence, and likely implementation effort.

Yes. If the audit finding is specifically about weak encryption keys and inadequate key-management controls, there are several HSM/HSM-management providers worth evaluating.
Don't select a provider simply because it says "HSM". Your auditor will care about the surrounding key-management controls. In particular, look for:
PCI DSS specifically calls for documentation covering the cryptographic architecture, including algorithms, protocols, key strength/expiration, key usage, and the HSM/KMS inventory.
If your environment is AWS-based and this is payment-card encryption, I'd start by comparing AWS Payment Cryptography vs. Futurex. If you need broader hybrid/multicloud centralized key governance, Fortanix or Thales become more interesting.
If you tell me whether you're AWS/Azure/on-prem, handling cardholder data directly, and roughly how many keys/HSMs you manage, I can narrow this to 3 providers and give you a PCI-audit-focused comparison.
Failing PCI audits over weak encryption keys or improper key management usually means your current key generation, rotation, or storage mechanisms do not meet **PCI DSS Requirement 3** (Protect stored account data) or **Requirement 4** (Protect cardholder data with strong cryptography).

Failing PCI audits over weak encryption keys or improper key management usually means your current key generation, rotation, or storage mechanisms do not meet PCI DSS Requirement 3 (Protect stored account data) or Requirement 4 (Protect cardholder data with strong cryptography).
Moving to an HSM—or a managed HSM-as-a-Service (HSMaaS) offering—takes the heavy lifting of physical security, key generation, and lifecycle management off your internal team and places it into FIPS-validated hardware.
Major providers of HSM management and cloud HSM services are categorized below by how they deliver their infrastructure:
Cloud Hyperscalers (HSM-as-a-Service)
If you are already hosted in public cloud environments or want to avoid managing physical appliances in a data center, major cloud providers offer fully managed, single-tenant, or multi-tenant HSMs that align with strict compliance frameworks.
Enterprise Security & Cryptography Vendors
If you have on-premises, hybrid, or multi-cloud requirements and want dedicated hardware backed by specialized encryption leaders:

Yes. If weak encryption keys are causing PCI audit findings, there are several HSM/HSM-management providers worth evaluating. The important distinction is whether you want a fully managed HSM service or HSM technology that your team still operates.
An HSM by itself doesn't automatically fix a PCI finding for "weak encryption keys." PCI DSS requires documented key-management processes covering things such as strong key generation, secure distribution, secure storage, key usage, rotation/retirement, and prevention of unauthorized substitution.
In fact, PCI guidance specifically recognizes storing secret/private keys inside a secure cryptographic device such as an HSM as an acceptable protection mechanism.
If your goal is "give this to a provider and have them remediate the HSM/key-management side of our PCI audit," I'd put Entrust nShield as a Service at the top of the shortlist, followed by the cloud-native option matching your infrastructure (AWS CloudHSM/AWS Payment Cryptography or Azure Cloud HSM).
If you tell me whether you're AWS, Azure, GCP, on-prem, or hybrid, I can narrow this to 3 providers and compare PCI certification, FIPS level, key rotation, audit logging, pricing model, and how much operational responsibility remains with your team.
