Infisical

Infisical is an identity security platform for managing application secrets, certificates, and privileged access across cloud, on-premises, and AI infrastructure. It best suits teams that need centralized controls across environments and want a choice between hosted and self-managed deployment. Its breadth is a strength, but certificate quotas and per-identity pricing make plan fit worth checking carefully.

Overview

Infisical brings secrets, certificate lifecycle management, and privileged access into one platform. Secrets can be synced, rotated, and audited across workloads; access can be scoped by environment, path, and identity. Teams can use Infisical Cloud or host it on their own infrastructure, a meaningful choice for organizations with deployment constraints.

The platform also addresses newer operational needs: dynamic secrets provide short-lived credentials, while Agent Proxy supplies real secrets at the proxy and gives an AI agent placeholders, with requests logged. Its listed integrations span cloud services, CI/CD tools, monitoring, databases, and OpenAI. Infisical says it encrypts sensitive data with AES-256-GCM and supports external KMS and HSM integrations.

Key features

Secrets and access

Centralized syncing, scheduled rotation, on-demand dynamic credentials, and auditing make Infisical suitable for teams managing secrets across multiple environments. Fine-grained role-based access can be scoped to environment, path, and identity, which gives administrators more control than a single broad project-level permission. The free secrets tier’s five-identity cap, however, is a real boundary for growing teams.

Certificates and privileged access

Certificate Management automates issuance, renewal, and revocation and supports private certificate authorities. The free certificate tier is tightly bounded: one CA, 10 active certificates, up to five SANs per certificate, and no wildcard SANs. That can be a useful starting point, but organizations with wildcard needs or larger certificate estates will need another plan.

Privileged Access uses short-lived, identity-based sessions and provides auditing across infrastructure, databases, and sensitive systems. Its Pro plan adds audit logs and session recording with 30-day retention, but caps usage at 50 resources.

Pricing

Infisical has a free tier and paid plans, with paid plans offering a free trial that does not require a credit card. The products are priced in separate plan families, so the right cost depends on whether a team needs secrets management, certificates, privileged access, or a combination.

• Secrets Management Free: free, billed forever. It includes five identities, unlimited projects, and 100+ integrations. The identity cap makes it best for small teams or evaluation rather than broad rollout.
• Certificate Management Free: free, with one CA, up to 10 active certificates, and up to five SANs per certificate; wildcard SANs are excluded. It is a narrow but usable entry point for modest certificate needs.
• Privileged Access Pro: $2 a month, up to 50 resources, with audit logs and session recording retained for 30 days. The low stated price is paired with a clear resource ceiling.
• Secrets Management Pro: $20 a month, billed annually; the plan page shows $20 and $23 per identity/month. It includes unlimited identities, six environments per project, and 25 secret syncs. The environment and sync caps matter for teams with many deployment stages or destinations.
• Secrets Management Advanced: $40 a month, billed annually; the plan page shows $40 and $46 per identity/month. It raises the limits to 12 environments per project and 50 secret syncs, while retaining unlimited identities. This is the more suitable paid tier when Pro’s operational caps are too restrictive.
• Secrets Management Enterprise: custom pricing, billed annually, with custom audit-log retention and rate limits, a 99.99% SLA, and self-hosting or dedicated infrastructure.
• Certificate Management Enterprise: custom pricing, billed annually, with unlimited CAs, certificates, and SANs, plus FIPS and dedicated infrastructure.
• Privileged Access Enterprise: custom pricing, with unlimited resources, custom log and session retention, and Windows and RDP resources.

Check the identity-based figures shown for Secrets Management Pro and Advanced against the stated plan prices when estimating a bill; the page presents both $20/$23 and $40/$46 per identity/month figures. Enterprise tiers are the route for custom limits and infrastructure, but require a pricing conversation.

Platforms

Infisical supports API, Linux, self-hosted, web, and Windows. The Privileged Access Enterprise plan specifically includes Windows and RDP resources. Self-hosting is an option alongside Infisical Cloud, and integrations include AWS, Azure Key Vault, GitHub, GitLab, CircleCI, Datadog, OpenAI, PostgreSQL, and Vercel.

Who it's for

Infisical is a strong fit for engineering and security teams that want secrets, certificates, and privileged sessions managed under one platform, especially where short-lived credentials, detailed access scoping, or self-hosting matter. Smaller teams can start with the free tiers, but the identity, certificate, and resource caps make those plans less suitable for unrestricted production growth. Organizations needing bespoke retention, higher limits, or dedicated infrastructure should consider custom-priced Enterprise plans.

Pros and cons

• Pro: Secrets, certificates, and privileged access share one platform, reducing the need to manage these controls as entirely separate workflows.
• Pro: Self-hosting and cloud deployment accommodate different infrastructure preferences.
• Pro: Scheduled rotation, dynamic credentials, and scoped role-based access support tighter secret handling across environments.
• Con: Free certificate management excludes wildcard SANs and stops at 10 active certificates, limiting its reach for larger or wildcard-heavy setups.
• Con: Secrets Management Pro and Advanced cap environments and syncs, so teams should check their deployment topology before choosing a tier.
• Con: Enterprise features carry custom pricing, making costs harder to assess in advance.

Alternatives

For a broader comparison, see Secrets Management Tools. Consider these alternatives when their stated plans or focus better match your needs:

• Keyway may suit teams seeking a freemium option with Pro at €9 a month and 10 private repos, unlimited environments, and unlimited collaborators.
• Kubermatic Kubernetes Platform offers a free, open-source Community Edition under Apache License 2.0; consider it when that licensing and free entry point are the priority.
• Phase has a free tier for up to five users or service accounts, three apps, and three environments, with OAuth SSO and AI agent integration. It may fit a small team whose needs stay within those limits.
• SikkerKey offers a free Developer plan with 10 machines, one month of audit retention, and 20 webhook deliveries per day; it may fit a small machine-based setup.
• KeyEnv has a free tier for up to three projects and 100 secrets per environment, with CLI access and end-to-end encryption. It may suit a project-limited setup that values those inclusions.
• Stashbase is another freemium option for readers comparing secret-management products.
• Teller is a free, open-source universal secret manager for developers, for readers who prefer that approach.
• AWS Secrets Manager may fit readers already considering AWS; its Free Tier offers up to $200 in credits, available for six months after account creation, with credits expiring within 12 months.

Verdict

Choose Infisical if your team wants one platform for secrets, certificate lifecycle, and privileged sessions, with the option to self-host and controls such as dynamic credentials and scoped access. Its main advantage is that breadth; its main drawback is that free and paid tiers impose meaningful certificate, resource, environment, or sync limits, while Enterprise pricing is custom. Teams with modest needs can start free, but larger deployments should map their quotas and per-identity costs before committing.
