Infisical

Infisical is an identity security platform for managing application secrets, certificates and privileged access across cloud, on-premises and AI infrastructure. Secrets Management brings credentials together for syncing, rotation and auditing across environments and workloads, with role-based permissions scoped by environment, path and identity. Secrets can rotate on a schedule or be issued as short-lived dynamic credentials. Certificate Management supports private certificate authorities and automates issuance, renewal and revocation. Privileged Access provides short-lived, identity-based sessions with auditing across infrastructure, databases and sensitive systems. Agent Proxy keeps real secrets at the proxy while agents receive placeholders, and logs requests. Listed integrations include AWS, Azure Key Vault, GitHub, GitLab, CircleCI, Datadog, OpenAI and PostgreSQL. Infisical can be used as a cloud service or self-hosted on an organization's infrastructure. The company says sensitive data is encrypted with AES-256-GCM and supports external KMS and HSM integrations. A free plan is available; paid plans start at $20/mo (annual), and paid plans include a trial without a credit card. The free certificate plan is limited to 10 active certificates with up to five SANs each and no wildcard SANs.

Infisical combines secrets, certificate and privileged-access management with both cloud and self-hosted deployment options. Paid plans start at $20/mo (annual); free certificate use has stated certificate and SAN limits.

Infisical suits organizations that need to manage application credentials, certificates or privileged access across infrastructure. It supports cloud use and self-hosting, with API, Linux, web and Windows listed platforms.

Infisical is an identity-security platform that brings application secrets, certificates, and privileged access into one control layer. It suits engineering and security teams managing many environments, workloads, or infrastructure boundaries, especially those requiring either hosted or self-managed deployment. The trade-off is a broad product whose quotas and identity-based pricing need careful matching to your operation.

Overview

Infisical centralizes credentials for synchronization, scheduled rotation, and audit across applications and workloads. Role-based permissions can be narrowed by environment, path, and identity, which is more useful for organizations with distinct teams or production boundaries than for a small project with one shared vault.

It also covers certificate authorities and privileged sessions rather than stopping at secret storage. Dynamic secrets issue short-lived credentials on demand, while Agent Proxy keeps real values at the proxy and presents an AI agent with placeholders; requests are logged. Connections include AWS, Azure Key Vault, GitHub, GitLab, CircleCI, Datadog, OpenAI, PostgreSQL, Vercel, and many others. Infisical says data is encrypted with AES-256-GCM and can use external KMS and HSM integrations.

Key features

Secrets and access controls

Secret syncing, rotation, dynamic credentials, and auditing address the operational problem of long-lived values spread across environments. Fine-grained scoping is a meaningful strength when different identities need different paths or stages. CI/CD injection and Kubernetes integration make the service relevant to automated delivery and cluster workloads, not only application configuration.

Certificates and privileged access

Certificate Management supports private certificate authorities plus automated issuance, renewal, and revocation. Privileged Access creates short-lived, identity-based sessions with auditing for infrastructure, databases, and other sensitive systems. The combination can reduce the number of separate security products a larger team operates, but adds complexity if certificates or privileged sessions are outside your needs.

Agent security and assurance

Agent Proxy is a focused control for AI workflows: the agent handles placeholders while the proxy attaches secrets and records requests. Infisical says it receives penetration tests and vulnerability assessments twice yearly, including a recent full-coverage assessment by Cure53. Those statements support a security-conscious shortlist, though they do not replace your own compliance review.

Pricing

The freemium structure gives small teams a way to start, while paid plans expand environments, syncs, resources, and retention. Paid plans include a free trial without a credit card.

Free and entry plans

• Secrets Management Free: $$0 forever, with five identities, unlimited projects, and more than 100 integrations. It is a practical evaluation or small-team tier, but five identities can become restrictive as access needs grow.
• Certificate Management Free: free, one certificate authority, up to 10 active certificates, and up to five SANs per certificate. Wildcard SANs are not included, so teams with larger or wildcard-heavy certificate estates need a paid tier.
• Privileged Access Pro: $2 a month for up to 50 resources, audit logs, and session recording retained for 30 days. It is inexpensive for a contained resource set, but the resource ceiling and retention period matter for broader operations.

Paid secrets and enterprise tiers

Secrets Management Pro costs $20 a month billed annually; the page also shows $20 and $23 per identity/month. It includes unlimited identities, six environments per project, and 25 secret syncs. Advanced is $40 a month billed annually, with displayed $40 and $46 per identity/month, 12 environments per project, and 50 syncs. These tiers fit growing organizations, with Advanced justified when environment or sync capacity is the constraint.

Secrets Management Enterprise uses custom annual pricing and adds custom audit-log retention and rate limits, a 99.99% SLA, and self-hosting or dedicated infrastructure. Certificate Management Enterprise has custom annual pricing with unlimited CAs, certificates, and SANs, plus FIPS and dedicated infrastructure. Privileged Access Enterprise is custom-priced with unlimited resources, custom log and session retention, and Windows and RDP resources.

Platforms

Infisical is offered through its web interface and API, with Linux and Windows support. Deployment can be Infisical Cloud or self-hosted on organizational infrastructure, giving regulated or infrastructure-sensitive teams more control over placement.

Who it's for

Choose Infisical when one program must govern secrets, certificates, and privileged access across cloud, on-premises, or AI infrastructure. It is particularly well suited to teams needing scoped roles, automated rotation, CI/CD or Kubernetes integration, and a self-hosting option. A small team needing only a basic secret store may find its broader surface and tier limits unnecessary.

Pros and cons

• Pro: Secrets, certificate lifecycle, and privileged sessions share one platform, reducing tool sprawl for larger security programs.
• Pro: Self-hosting, external KMS/HSM support, and a 99.99% Enterprise SLA address demanding deployment and availability requirements.
• Pro: Dynamic secrets and Agent Proxy reduce exposure from persistent credentials and direct AI-agent access.
• Con: The free certificate tier allows only 10 active certificates, five SANs each, and no wildcard SANs.
• Con: Secrets Pro and Advanced impose environment and sync quotas, while displayed per-identity prices make scaling costs worth modeling.
• Con: Enterprise capabilities and pricing require a sales-led commitment rather than a published self-serve cost.

Alternatives

For a broader directory of secret-storage choices, see Secrets Management Tools. Consider R4 if you want a freemium service spanning mobile, desktop, web, API, and browser-extension platforms with usage-based pricing. BeyondTrust Remote Support is a better fit when remote support is the priority and a paid, sales-quoted deployment is acceptable.

Delinea Identity Threat Protection suits buyers seeking a paid identity-threat product priced by quote. Choose Keyway for a freemium secrets tool with published Pro and Team tiers, including unlimited environments on Pro. VMware Secrets Manager is the simpler choice for free, open-source, Kubernetes-oriented deployment.

AWS Secrets Manager fits teams already centered on AWS and eligible for its time-limited Free Tier credits. dotenvx is preferable when a free, open-source CLI and SDK workflow is the main requirement. Envshed is a lightweight freemium option with a free developer tier capped at two members and three projects.

Verdict

Infisical is a strong choice for organizations that want centralized secrets, certificate automation, and audited privileged access with cloud or self-hosted deployment. Choose it for breadth, dynamic credentials, and infrastructure flexibility; look elsewhere if you need only simple secret storage or if the certificate, environment, sync, or identity limits do not fit your scale.
