Infisical: cost, fit and limits
Infisical is an open-source secrets management platform made by Infisical, Inc. that stores API keys and credentials, syncs them to cloud and CI systems, rotates them and issues dynamic secrets. The same company also sells certificate management, privileged access and an agent vault product, each priced separately.
What to know first
Infisical sells four product lines separately: secrets management, privileged access, certificate management and Agent Vault. This page covers the secrets line, billed per identity, which means human users and machine identities both count. A free plan exists for small projects, and paid plans come with a 30-day trial without a card. The step from Pro to Advanced matters most, because dynamic secrets, gateways and full rotation start there.

Who Infisical is best for
Small platform teams
The free plan allows 5 identities, 3 environments and 10 secret syncs, enough for a side project or a small service before anyone has to approve spend.
Teams that want to self-host
The open-source core is MIT-licensed and free to self-host, and the vendor says licensed, supported self-hosting, including air-gapped setups, is arranged through sales.
Companies with strict key custody rules
Project data keys can sit in AWS KMS, AWS CloudHSM or GCP KMS, and the root key can come from an external HSM such as Thales Luna.
Security teams adding agent access
The vendor sells Agent Vault with the first 5,000 brokered requests per month free, then $2 per 1,000, for AI agents that call external services.

What Infisical does
- Secret syncs
- Secrets can be synced out to other systems. The free plan allows 10 syncs, which is a real constraint for a team with many cloud services, so count destinations before choosing a plan.
- Dynamic secrets and rotation
- Short-lived database and cloud credentials, gateways and full rotation start on Advanced. Pro lacks them, which matters for teams that bought Pro expecting rotation. Test it on a staging database first.
- Layered encryption
- Data is encrypted with AES-256-GCM using a random nonce. An operator root key protects an internal KMS key, which protects data keys for each organization and project.
- Certificate management
- A separate product offers internal CAs, ACME enrollment and, on Enterprise, unlimited CAs, wildcard SANs and Microsoft AD CS. Its free tier allows 2 internal CAs and 10 active SANs.
- Privileged access
- A per-user product adds access requests, approval workflows, credential rotation and session recording. Pro is $20 per user per month with up to 50 resources and a 14-day trial.
How Infisical handles your data
Infisical Cloud has a US region and an EU region, and runs on AWS with Multi-AZ databases and Cloudflare in front. Cross-region replication covers disaster recovery, with additional replication to GCP. Sensitive data is encrypted with AES-256-GCM, and Enterprise can use external KMS or HSM keys and a FIPS-compliant configuration. The security documentation mentions penetration tests twice a year, a Cure53 test and attestation letters on request, but no SOC 2 or ISO 27001 statement. The privacy policy does not mention AI, and retention periods are not covered.
Where Infisical falls short in practice
- Identity counting drives cost. Pro and Advanced bill per identity, and machine identities count. A company with many pipelines and service accounts can pay more for automation than for its engineers.
- Certifications are not stated. The pages read give pen test and FIPS details but no SOC 2 or ISO 27001 claim. Buyers with a compliance checklist should ask for the Trust Center report.
- Rotation is not on Pro. The cheaper paid tier excludes dynamic secrets, gateways and full rotation. Teams whose reason for buying is rotation must budget at the Advanced rate of $40 per identity.

Alternatives to Infisical
Infisical: common questions
Can Infisical run entirely on our own servers?
Yes. The pricing page says every product has an MIT-licensed open-source core that is free to self-host. Licensed, supported self-hosting, including air-gapped deployments, requires contacting sales. The security documentation notes that self-hosted servers do not enforce rate limits, so you need an external limiter.
Which Infisical plan do I need for dynamic secrets?
Dynamic secrets, gateways and full rotation are listed on the Advanced plan at $40 per identity per month billed annually, or $46 monthly. Pro at $20 does not list them. Enterprise adds SCIM, LDAP, approval workflows and external KMS or HSM support on top.
Does Infisical offer EU hosting?
Infisical Cloud has a US region at app.infisical.com and an EU region at eu.infisical.com, according to its vulnerability disclosure page. The pages read do not describe how data is kept apart between regions, so ask for the sub-processor list and the region assignment in the contract.
How long does Infisical keep audit logs?
Pro lists 30-day audit retention and Advanced lists 90 days. Enterprise adds audit log streaming, so logs can be forwarded to your own system for longer retention. The security documentation does not state retention for secrets, backups or deleted data.
Is there a trial for Infisical's paid plans?
The pricing page says paid plans include a 30-day free trial with no credit card required. The privileged access product has a 14-day trial for its Pro tier. The free plan has no expiry but is limited to 5 identities, 3 environments and 10 secret syncs.
